+# @serialport/BindingAbstract
+
+This Abstract binding class is the base for all serialport bindings. You wouldn't use this class directly but instead extend it to make a new binding for a different platform or underling technology.
+
+This is currently used for the win32, linux, darwin and mock bindings.
+
+This is how you use it.
+```js
+class MockBinding extends AbstractBinding {
+ constructor(opt) {
+ super(opt)
+ }
+}
+```

+# @serialport/Bindings
+
+The `Binding` is how Node-SerialPort talks to the underlying system. By default, we auto detect Windows, Linux and OS X, and load the appropriate module for your system. You can assign `SerialPort.Binding` to any binding you like. Find more by searching ["serialport-binding" at npm](https://www.npmjs.com/search?q=serialport-binding).
+
+Learn more at our [bindings documentation](https://serialport.io/docs/api-bindings) page.

+# @serialport/Stream
+
+The serialport stream interface. This package requires bindings to work.
+
+You'd use this if you want to keep your package size down by requiring only the parts of serialport that you want to use. It is used internally in the `serialport` package.
+
+This is how you use it.
+```js
+
+const SerialPort = require('@serialport/stream')
+const Binding = require('@serialport/bindings')
+SerialPort.Binding = Binding
+const port = new Serialport('/dev/ttyay')
+```
+
+Learn more at our [stream documentation](https://serialport.io/docs/api-stream) page.

+ * @param {errorCallback=} openCallback - Called after a connection is opened. If this is not provided and an error occurs, it will be emitted on the port's `error` event. The callback will NOT be called if `autoOpen` is set to `false` in the `openOptions` as the open will not be performed.

+/**
+ * Writes data to the given serial port. Buffers written data if the port is not open.
+
+The write operation is non-blocking. When it returns, data might still not have been written to the serial port. See `drain()`.
+
+Some devices, like the Arduino, reset when you open a connection to them. In such cases, immediately writing to the device will cause lost data as they wont be ready to receive the data. This is often worked around by having the Arduino send a "ready" byte that your Node program waits for before writing. You can also often get away with waiting around 400ms.
+
+If a port is disconnected during a write, the write will error in addition to the `close` event.
+
+From the [stream docs](https://nodejs.org/api/stream.html#stream_writable_write_chunk_encoding_callback) write errors don't always provide the error in the callback, sometimes they use the error event.
+> If an error occurs, the callback may or may not be called with the error as its first argument. To reliably detect write errors, add a listener for the 'error' event.
+
+In addition to the usual `stream.write` arguments (`String` and `Buffer`), `write()` can accept arrays of bytes (positive numbers under 256) which is passed to `Buffer.from([])` for conversion. This extra functionality is pretty sweet.
+ * @method SerialPort.prototype.write
+ * @param {(string|array|buffer)} data Accepts a [`Buffer`](http://nodejs.org/api/buffer.html) object, or a type that is accepted by the `Buffer` constructor (e.g. an array of bytes or a string).
+ * @param {string=} encoding The encoding, if chunk is a string. Defaults to `'utf8'`. Also accepts `'ascii'`, `'base64'`, `'binary'`, and `'hex'` See [Buffers and Character Encodings](https://nodejs.org/api/buffer.html#buffer_buffers_and_character_encodings) for all available options.
+ * @param {function=} callback Called once the write operation finishes. Data may not yet be flushed to the underlying port. No arguments.
+ * @returns {boolean} `false` if the stream wishes for the calling code to wait for the `'drain'` event to be emitted before continuing to write additional data; otherwise `true`.

+## FAQ
+
+### Why do you test for codes not in the ECMA 48 standard?
+
+Some of the codes we run as a test are codes that we acquired finding various lists of non-standard or manufacturer specific codes. If I recall correctly, we test for both standard and non-standard codes, as most of them follow the same or similar format and can be safely matched in strings without the risk of removing actual string content. There are a few non-standard control codes that do not follow the traditional format (i.e. they end in numbers) thus forcing us to exclude them from the test because we cannot reliably match them.
+
+On the historical side, those ECMA standards were established in the early 90's whereas the VT100, for example, was designed in the mid/late 70's. At that point in time, control codes were still pretty ungoverned and engineers used them for a multitude of things, namely to activate hardware ports that may have been proprietary. Somewhere else you see a similar 'anarchy' of codes is in the x86 architecture for processors; there are a ton of "interrupts" that can mean different things on certain brands of processors, most of which have been phased out.

+aproba
+======
+
+A ridiculously light-weight function argument validator
+
+```
+var validate = require("aproba")
+
+function myfunc(a, b, c) {
+ // `a` must be a string, `b` a number, `c` a function
+ validate('SNF', arguments) // [a,b,c] is also valid
+}
+
+myfunc('test', 23, function () {}) // ok
+myfunc(123, 23, function () {}) // type error
+myfunc('test', 23) // missing arg error
+myfunc('test', 23, function () {}, true) // too many args error
+
+```
+
+Valid types are:
+
+| type | description
+| :--: | :----------
+| * | matches any type
+| A | `Array.isArray` OR an `arguments` object
+| S | typeof == string
+| N | typeof == number
+| F | typeof == function
+| O | typeof == object and not type A and not type E
+| B | typeof == boolean
+| E | `instanceof Error` OR `null` **(special: see below)**
+| Z | == `null`
+
+Validation failures throw one of three exception types, distinguished by a
+`code` property of `EMISSINGARG`, `EINVALIDTYPE` or `ETOOMANYARGS`.
+
+If you pass in an invalid type then it will throw with a code of
+`EUNKNOWNTYPE`.
+
+If an **error** argument is found and is not null then the remaining
+arguments are optional. That is, if you say `ESO` then that's like using a
+non-magical `E` in: `E|ESO|ZSO`.
+
+### But I have optional arguments?!
+
+You can provide more than one signature by separating them with pipes `|`.
+If any signature matches the arguments then they'll be considered valid.
+
+So for example, say you wanted to write a signature for
+`fs.createWriteStream`. The docs for it describe it thusly:
+
+```
+fs.createWriteStream(path[, options])
+```
+
+This would be a signature of `SO|S`. That is, a string and and object, or
+just a string.
+
+Now, if you read the full `fs` docs, you'll see that actually path can ALSO
+be a buffer. And options can be a string, that is:
+```
+path <String> | <Buffer>
+options <String> | <Object>
+```
+
+To reproduce this you have to fully enumerate all of the possible
+combinations and that implies a signature of `SO|SS|OO|OS|S|O`. The
+awkwardness is a feature: It reminds you of the complexity you're adding to
+your API when you do this sort of thing.
+
+
+### Browser support
+
+This has no dependencies and should work in browsers, though you'll have
+noisier stack traces.
+
+### Why this exists
+
+I wanted a very simple argument validator. It needed to do two things:
+
+1. Be more concise and easier to use than assertions
+
+2. Not encourage an infinite bikeshed of DSLs
+
+This is why types are specified by a single character and there's no such
+thing as an optional argument.
+
+This is not intended to validate user data. This is specifically about
+asserting the interface of your functions.
+
+If you need greater validation, I encourage you to write them by hand or
+look elsewhere.

+Hi, figured we could actually use a changelog now:
+
+## 1.1.5 2018-05-24
+
+* [#92](https://github.com/iarna/are-we-there-yet/pull/92) Fix bug where
+ `finish` would throw errors when including `TrackerStream` objects in
+ `TrackerGroup` collections. (@brianloveswords)
+
+## 1.1.4 2017-04-21
+
+* Fix typo in package.json
+
+## 1.1.3 2017-04-21
+
+* Improve documentation and limit files included in the distribution.
+
+## 1.1.2 2016-03-15
+
+* Add tracker group cycle detection and tests for it
+
+## 1.1.1 2016-01-29
+
+* Fix a typo in stream completion tracker
+
+## 1.1.0 2016-01-29
+
+* Rewrote completion percent computation to be low impact– no more walking a
+ tree of completion groups every time we need this info. Previously, with
+ medium sized tree of completion groups, even a relatively modest number of
+ calls to the top level `completed()` method would result in absurd numbers
+ of calls overall as it walked down the tree. We now, instead, keep track as
+ we bubble up changes, so the computation is limited to when data changes and
+ to the depth of that one branch, instead of _every_ node. (Plus, we were already
+ incurring _this_ cost, since we already bubbled out changes.)
+* Moved different tracker types out to their own files.
+* Made tests test for TOO MANY events too.
+* Standarized the source code formatting

+are-we-there-yet
+----------------
+
+Track complex hiearchies of asynchronous task completion statuses. This is
+intended to give you a way of recording and reporting the progress of the big
+recursive fan-out and gather type workflows that are so common in async.
+
+What you do with this completion data is up to you, but the most common use case is to
+feed it to one of the many progress bar modules.
+
+Most progress bar modules include a rudamentary version of this, but my
+needs were more complex.
+
+Usage
+=====
+
+```javascript
+var TrackerGroup = require("are-we-there-yet").TrackerGroup
+
+var top = new TrackerGroup("program")
+
+var single = top.newItem("one thing", 100)
+single.completeWork(20)
+
+console.log(top.completed()) // 0.2
+
+fs.stat("file", function(er, stat) {
+ if (er) throw er
+ var stream = top.newStream("file", stat.size)
+ console.log(top.completed()) // now 0.1 as single is 50% of the job and is 20% complete
+ // and 50% * 20% == 10%
+ fs.createReadStream("file").pipe(stream).on("data", function (chunk) {
+ // do stuff with chunk
+ })
+ top.on("change", function (name) {
+ // called each time a chunk is read from "file"
+ // top.completed() will start at 0.1 and fill up to 0.6 as the file is read
+ })
+})
+```
+
+Shared Methods
+==============
+
+* var completed = tracker.completed()
+
+Implemented in: `Tracker`, `TrackerGroup`, `TrackerStream`
+
+Returns the ratio of completed work to work to be done. Range of 0 to 1.
+
+* tracker.finish()
+
+Implemented in: `Tracker`, `TrackerGroup`
+
+Marks the tracker as completed. With a TrackerGroup this marks all of its
+components as completed.
+
+Marks all of the components of this tracker as finished, which in turn means
+that `tracker.completed()` for this will now be 1.
+
+This will result in one or more `change` events being emitted.
+
+Events
+======
+
+All tracker objects emit `change` events with the following arguments:
+
+```
+function (name, completed, tracker)
+```
+
+`name` is the name of the tracker that originally emitted the event,
+or if it didn't have one, the first containing tracker group that had one.
+
+`completed` is the percent complete (as returned by `tracker.completed()` method).
+
+`tracker` is the tracker object that you are listening for events on.
+
+TrackerGroup
+============
+
+* var tracker = new TrackerGroup(**name**)
+
+ * **name** *(optional)* - The name of this tracker group, used in change
+ notifications if the component updating didn't have a name. Defaults to undefined.
+
+Creates a new empty tracker aggregation group. These are trackers whose
+completion status is determined by the completion status of other trackers.
+
+* tracker.addUnit(**otherTracker**, **weight**)
+
+ * **otherTracker** - Any of the other are-we-there-yet tracker objects
+ * **weight** *(optional)* - The weight to give the tracker, defaults to 1.
+
+Adds the **otherTracker** to this aggregation group. The weight determines
+how long you expect this tracker to take to complete in proportion to other
+units. So for instance, if you add one tracker with a weight of 1 and
+another with a weight of 2, you're saying the second will take twice as long
+to complete as the first. As such, the first will account for 33% of the
+completion of this tracker and the second will account for the other 67%.
+
+Returns **otherTracker**.
+
+* var subGroup = tracker.newGroup(**name**, **weight**)
+
+The above is exactly equivalent to:
+
+```javascript
+ var subGroup = tracker.addUnit(new TrackerGroup(name), weight)
+```
+
+* var subItem = tracker.newItem(**name**, **todo**, **weight**)
+
+The above is exactly equivalent to:
+
+```javascript
+ var subItem = tracker.addUnit(new Tracker(name, todo), weight)
+```
+
+* var subStream = tracker.newStream(**name**, **todo**, **weight**)
+
+The above is exactly equivalent to:
+
+```javascript
+ var subStream = tracker.addUnit(new TrackerStream(name, todo), weight)
+```
+
+* console.log( tracker.debug() )
+
+Returns a tree showing the completion of this tracker group and all of its
+children, including recursively entering all of the children.
+
+Tracker
+=======
+
+* var tracker = new Tracker(**name**, **todo**)
+
+ * **name** *(optional)* The name of this counter to report in change
+ events. Defaults to undefined.
+ * **todo** *(optional)* The amount of work todo (a number). Defaults to 0.
+
+Ordinarily these are constructed as a part of a tracker group (via
+`newItem`).
+
+* var completed = tracker.completed()
+
+Returns the ratio of completed work to work to be done. Range of 0 to 1. If
+total work to be done is 0 then it will return 0.
+
+* tracker.addWork(**todo**)
+
+ * **todo** A number to add to the amount of work to be done.
+
+Increases the amount of work to be done, thus decreasing the completion
+percentage. Triggers a `change` event.
+
+* tracker.completeWork(**completed**)
+
+ * **completed** A number to add to the work complete
+
+Increase the amount of work complete, thus increasing the completion percentage.
+Will never increase the work completed past the amount of work todo. That is,
+percentages > 100% are not allowed. Triggers a `change` event.
+
+* tracker.finish()
+
+Marks this tracker as finished, tracker.completed() will now be 1. Triggers
+a `change` event.
+
+TrackerStream
+=============
+
+* var tracker = new TrackerStream(**name**, **size**, **options**)
+
+ * **name** *(optional)* The name of this counter to report in change
+ events. Defaults to undefined.
+ * **size** *(optional)* The number of bytes being sent through this stream.
+ * **options** *(optional)* A hash of stream options
+
+The tracker stream object is a pass through stream that updates an internal
+tracker object each time a block passes through. It's intended to track
+downloads, file extraction and other related activities. You use it by piping
+your data source into it and then using it as your data source.
+
+If your data has a length attribute then that's used as the amount of work
+completed when the chunk is passed through. If it does not (eg, object
+streams) then each chunk counts as completing 1 unit of work, so your size
+should be the total number of objects being streamed.
+
+* tracker.addWork(**todo**)
+
+ * **todo** Increase the expected overall size by **todo** bytes.
+
+Increases the amount of work to be done, thus decreasing the completion
+percentage. Triggers a `change` event.

+base64-js
+=========
+
+`base64-js` does basic base64 encoding/decoding in pure JS.
+
+[](http://travis-ci.org/beatgammit/base64-js)
+
+Many browsers already have base64 encoding/decoding functionality, but it is for text data, not all-purpose binary data.
+
+Sometimes encoding/decoding binary data in the browser is useful, and that is what this module does.
+
+## install
+
+With [npm](https://npmjs.org) do:
+
+`npm install base64-js` and `var base64js = require('base64-js')`
+
+For use in web browsers do:
+
+`<script src="base64js.min.js"></script>`
+
+[Get supported base64-js with the Tidelift Subscription](https://tidelift.com/subscription/pkg/npm-base64-js?utm_source=npm-base64-js&utm_medium=referral&utm_campaign=readme)
+
+## methods
+
+`base64js` has three exposed functions, `byteLength`, `toByteArray` and `fromByteArray`, which both take a single argument.
+
+* `byteLength` - Takes a base64 string and returns length of byte array
+* `toByteArray` - Takes a base64 string and returns a byte array
+* `fromByteArray` - Takes a byte array and returns a base64 string
+

+node-bindings
+=============
+### Helper module for loading your native module's `.node` file
+
+This is a helper module for authors of Node.js native addon modules.
+It is basically the "swiss army knife" of `require()`ing your native module's
+`.node` file.
+
+Throughout the course of Node's native addon history, addons have ended up being
+compiled in a variety of different places, depending on which build tool and which
+version of node was used. To make matters worse, now the `gyp` build tool can
+produce either a __Release__ or __Debug__ build, each being built into different
+locations.
+
+This module checks _all_ the possible locations that a native addon would be built
+at, and returns the first one that loads successfully.
+
+
+Installation
+------------
+
+Install with `npm`:
+
+``` bash
+$ npm install --save bindings
+```
+
+Or add it to the `"dependencies"` section of your `package.json` file.
+
+
+Example
+-------
+
+`require()`ing the proper bindings file for the current node version, platform
+and architecture is as simple as:
+
+``` js
+var bindings = require('bindings')('binding.node')
+
+// Use your bindings defined in your C files
+bindings.your_c_function()
+```
+
+
+Nice Error Output
+-----------------
+
+When the `.node` file could not be loaded, `node-bindings` throws an Error with
+a nice error message telling you exactly what was tried. You can also check the
+`err.tries` Array property.
+
+```
+Error: Could not load the bindings file. Tried:
+ → /Users/nrajlich/ref/build/binding.node
+ → /Users/nrajlich/ref/build/Debug/binding.node
+ → /Users/nrajlich/ref/build/Release/binding.node
+ → /Users/nrajlich/ref/out/Debug/binding.node
+ → /Users/nrajlich/ref/Debug/binding.node
+ → /Users/nrajlich/ref/out/Release/binding.node
+ → /Users/nrajlich/ref/Release/binding.node
+ → /Users/nrajlich/ref/build/default/binding.node
+ → /Users/nrajlich/ref/compiled/0.8.2/darwin/x64/binding.node
+ at bindings (/Users/nrajlich/ref/node_modules/bindings/bindings.js:84:13)
+ at Object.<anonymous> (/Users/nrajlich/ref/lib/ref.js:5:47)
+ at Module._compile (module.js:449:26)
+ at Object.Module._extensions..js (module.js:467:10)
+ at Module.load (module.js:356:32)
+ at Function.Module._load (module.js:312:12)
+ ...
+```
+
+The searching for the `.node` file will originate from the first directory in which has a `package.json` file is found.

+# bl *(BufferList)*
+
+[](https://travis-ci.com/rvagg/bl/)
+
+**A Node.js Buffer list collector, reader and streamer thingy.**
+
+[](https://nodei.co/npm/bl/)
+
+**bl** is a storage object for collections of Node Buffers, exposing them with the main Buffer readable API. Also works as a duplex stream so you can collect buffers from a stream that emits them and emit buffers to a stream that consumes them!
+
+The original buffers are kept intact and copies are only done as necessary. Any reads that require the use of a single original buffer will return a slice of that buffer only (which references the same memory as the original buffer). Reads that span buffers perform concatenation as required and return the results transparently.
+
+```js
+const { BufferList } = require('bl')
+
+const bl = new BufferList()
+bl.append(Buffer.from('abcd'))
+bl.append(Buffer.from('efg'))
+bl.append('hi') // bl will also accept & convert Strings
+bl.append(Buffer.from('j'))
+bl.append(Buffer.from([ 0x3, 0x4 ]))
+
+console.log(bl.length) // 12
+
+console.log(bl.slice(0, 10).toString('ascii')) // 'abcdefghij'
+console.log(bl.slice(3, 10).toString('ascii')) // 'defghij'
+console.log(bl.slice(3, 6).toString('ascii')) // 'def'
+console.log(bl.slice(3, 8).toString('ascii')) // 'defgh'
+console.log(bl.slice(5, 10).toString('ascii')) // 'fghij'
+
+console.log(bl.indexOf('def')) // 3
+console.log(bl.indexOf('asdf')) // -1
+
+// or just use toString!
+console.log(bl.toString()) // 'abcdefghij\u0003\u0004'
+console.log(bl.toString('ascii', 3, 8)) // 'defgh'
+console.log(bl.toString('ascii', 5, 10)) // 'fghij'
+
+// other standard Buffer readables
+console.log(bl.readUInt16BE(10)) // 0x0304
+console.log(bl.readUInt16LE(10)) // 0x0403
+```
+
+Give it a callback in the constructor and use it just like **[concat-stream](https://github.com/maxogden/node-concat-stream)**:
+
+```js
+const { BufferListStream } = require('bl')
+const fs = require('fs')
+
+fs.createReadStream('README.md')
+ .pipe(BufferListStream((err, data) => { // note 'new' isn't strictly required
+ // `data` is a complete Buffer object containing the full data
+ console.log(data.toString())
+ }))
+```
+
+Note that when you use the *callback* method like this, the resulting `data` parameter is a concatenation of all `Buffer` objects in the list. If you want to avoid the overhead of this concatenation (in cases of extreme performance consciousness), then avoid the *callback* method and just listen to `'end'` instead, like a standard Stream.
+
+Or to fetch a URL using [hyperquest](https://github.com/substack/hyperquest) (should work with [request](http://github.com/mikeal/request) and even plain Node http too!):
+
+```js
+const hyperquest = require('hyperquest')
+const { BufferListStream } = require('bl')
+
+const url = 'https://raw.github.com/rvagg/bl/master/README.md'
+
+hyperquest(url).pipe(BufferListStream((err, data) => {
+ console.log(data.toString())
+}))
+```
+
+Or, use it as a readable stream to recompose a list of Buffers to an output source:
+
+```js
+const { BufferListStream } = require('bl')
+const fs = require('fs')
+
+var bl = new BufferListStream()
+bl.append(Buffer.from('abcd'))
+bl.append(Buffer.from('efg'))
+bl.append(Buffer.from('hi'))
+bl.append(Buffer.from('j'))
+
+bl.pipe(fs.createWriteStream('gibberish.txt'))
+```

+<a name="ctor"></a>
+### new BufferList([ Buffer | Buffer array | BufferList | BufferList array | String ])
+No arguments are _required_ for the constructor, but you can initialise the list by passing in a single `Buffer` object or an array of `Buffer` objects.
+
+`new` is not strictly required, if you don't instantiate a new object, it will be done automatically for you so you can create a new instance simply with:
+
+```js
+const { BufferList } = require('bl')
+const bl = BufferList()
+
+// equivalent to:
+
+const { BufferList } = require('bl')
+const bl = new BufferList()
+```
+
+--------------------------------------------------------
+<a name="isBufferList"></a>
+### BufferList.isBufferList(obj)
+Determines if the passed object is a `BufferList`. It will return `true` if the passed object is an instance of `BufferList` **or** `BufferListStream` and `false` otherwise.
+
+N.B. this won't return `true` for `BufferList` or `BufferListStream` instances created by versions of this library before this static method was added.
+
+--------------------------------------------------------
+<a name="length"></a>
+### bl.length
+Get the length of the list in bytes. This is the sum of the lengths of all of the buffers contained in the list, minus any initial offset for a semi-consumed buffer at the beginning. Should accurately represent the total number of bytes that can be read from the list.
+
+--------------------------------------------------------
+<a name="append"></a>
+### bl.append(Buffer | Buffer array | BufferList | BufferList array | String)
+`append(buffer)` adds an additional buffer or BufferList to the internal list. `this` is returned so it can be chained.
+
+--------------------------------------------------------
+<a name="get"></a>
+### bl.get(index)
+`get()` will return the byte at the specified index.
+
+--------------------------------------------------------
+<a name="indexOf"></a>
+### bl.indexOf(value[, byteOffset][, encoding])
+`get()` will return the byte at the specified index.
+`indexOf()` method returns the first index at which a given element can be found in the BufferList, or -1 if it is not present.
+
+--------------------------------------------------------
+<a name="slice"></a>
+### bl.slice([ start, [ end ] ])
+`slice()` returns a new `Buffer` object containing the bytes within the range specified. Both `start` and `end` are optional and will default to the beginning and end of the list respectively.
+
+If the requested range spans a single internal buffer then a slice of that buffer will be returned which shares the original memory range of that Buffer. If the range spans multiple buffers then copy operations will likely occur to give you a uniform Buffer.
+
+--------------------------------------------------------
+<a name="shallowSlice"></a>
+### bl.shallowSlice([ start, [ end ] ])
+`shallowSlice()` returns a new `BufferList` object containing the bytes within the range specified. Both `start` and `end` are optional and will default to the beginning and end of the list respectively.
+
+No copies will be performed. All buffers in the result share memory with the original list.
+
+--------------------------------------------------------
+<a name="copy"></a>
+### bl.copy(dest, [ destStart, [ srcStart [, srcEnd ] ] ])
+`copy()` copies the content of the list in the `dest` buffer, starting from `destStart` and containing the bytes within the range specified with `srcStart` to `srcEnd`. `destStart`, `start` and `end` are optional and will default to the beginning of the `dest` buffer, and the beginning and end of the list respectively.
+
+--------------------------------------------------------
+<a name="duplicate"></a>
+### bl.duplicate()
+`duplicate()` performs a **shallow-copy** of the list. The internal Buffers remains the same, so if you change the underlying Buffers, the change will be reflected in both the original and the duplicate. This method is needed if you want to call `consume()` or `pipe()` and still keep the original list.Example:
+
+```js
+var bl = new BufferListStream()
+
+bl.append('hello')
+bl.append(' world')
+bl.append('\n')
+
+bl.duplicate().pipe(process.stdout, { end: false })
+
+console.log(bl.toString())
+```
+
+--------------------------------------------------------
+<a name="consume"></a>
+### bl.consume(bytes)
+`consume()` will shift bytes *off the start of the list*. The number of bytes consumed don't need to line up with the sizes of the internal Buffers—initial offsets will be calculated accordingly in order to give you a consistent view of the data.
+
+--------------------------------------------------------
+<a name="toString"></a>
+### bl.toString([encoding, [ start, [ end ]]])
+`toString()` will return a string representation of the buffer. The optional `start` and `end` arguments are passed on to `slice()`, while the `encoding` is passed on to `toString()` of the resulting Buffer. See the [Buffer#toString()](http://nodejs.org/docs/latest/api/buffer.html#buffer_buf_tostring_encoding_start_end) documentation for more information.
+
+--------------------------------------------------------
+<a name="readXX"></a>
+### bl.readDoubleBE(), bl.readDoubleLE(), bl.readFloatBE(), bl.readFloatLE(), bl.readInt32BE(), bl.readInt32LE(), bl.readUInt32BE(), bl.readUInt32LE(), bl.readInt16BE(), bl.readInt16LE(), bl.readUInt16BE(), bl.readUInt16LE(), bl.readInt8(), bl.readUInt8()
+
+All of the standard byte-reading methods of the `Buffer` interface are implemented and will operate across internal Buffer boundaries transparently.
+
+See the <b><code>[Buffer](http://nodejs.org/docs/latest/api/buffer.html)</code></b> documentation for how these work.
+
+--------------------------------------------------------
+<a name="ctorStream"></a>
+### new BufferListStream([ callback | Buffer | Buffer array | BufferList | BufferList array | String ])
+**BufferListStream** is a Node **[Duplex Stream](http://nodejs.org/docs/latest/api/stream.html#stream_class_stream_duplex)**, so it can be read from and written to like a standard Node stream. You can also `pipe()` to and from a **BufferListStream** instance.
+
+The constructor takes an optional callback, if supplied, the callback will be called with an error argument followed by a reference to the **bl** instance, when `bl.end()` is called (i.e. from a piped stream). This is a convenient method of collecting the entire contents of a stream, particularly when the stream is *chunky*, such as a network stream.
+
+Normally, no arguments are required for the constructor, but you can initialise the list by passing in a single `Buffer` object or an array of `Buffer` object.
+
+`new` is not strictly required, if you don't instantiate a new object, it will be done automatically for you so you can create a new instance simply with:
+
+```js
+const { BufferListStream } = require('bl')
+const bl = BufferListStream()
+
+// equivalent to:
+
+const { BufferListStream } = require('bl')
+const bl = new BufferListStream()
+```
+
+N.B. For backwards compatibility reasons, `BufferListStream` is the **default** export when you `require('bl')`:
+
+```js
+const { BufferListStream } = require('bl')
+// equivalent to:
+const BufferListStream = require('bl')
+```

+### Streams Working Group
+
+The Node.js Streams is jointly governed by a Working Group
+(WG)
+that is responsible for high-level guidance of the project.
+
+The WG has final authority over this project including:
+
+* Technical direction
+* Project governance and process (including this policy)
+* Contribution policy
+* GitHub repository hosting
+* Conduct guidelines
+* Maintaining the list of additional Collaborators
+
+For the current list of WG members, see the project
+[README.md](./README.md#current-project-team-members).
+
+### Collaborators
+
+The readable-stream GitHub repository is
+maintained by the WG and additional Collaborators who are added by the
+WG on an ongoing basis.
+
+Individuals making significant and valuable contributions are made
+Collaborators and given commit-access to the project. These
+individuals are identified by the WG and their addition as
+Collaborators is discussed during the WG meeting.
+
+_Note:_ If you make a significant contribution and are not considered
+for commit-access log an issue or contact a WG member directly and it
+will be brought up in the next WG meeting.
+
+Modifications of the contents of the readable-stream repository are
+made on
+a collaborative basis. Anybody with a GitHub account may propose a
+modification via pull request and it will be considered by the project
+Collaborators. All pull requests must be reviewed and accepted by a
+Collaborator with sufficient expertise who is able to take full
+responsibility for the change. In the case of pull requests proposed
+by an existing Collaborator, an additional Collaborator is required
+for sign-off. Consensus should be sought if additional Collaborators
+participate and there is disagreement around a particular
+modification. See _Consensus Seeking Process_ below for further detail
+on the consensus model used for governance.
+
+Collaborators may opt to elevate significant or controversial
+modifications, or modifications that have not found consensus to the
+WG for discussion by assigning the ***WG-agenda*** tag to a pull
+request or issue. The WG should serve as the final arbiter where
+required.
+
+For the current list of Collaborators, see the project
+[README.md](./README.md#members).
+
+### WG Membership
+
+WG seats are not time-limited. There is no fixed size of the WG.
+However, the expected target is between 6 and 12, to ensure adequate
+coverage of important areas of expertise, balanced with the ability to
+make decisions efficiently.
+
+There is no specific set of requirements or qualifications for WG
+membership beyond these rules.
+
+The WG may add additional members to the WG by unanimous consensus.
+
+A WG member may be removed from the WG by voluntary resignation, or by
+unanimous consensus of all other WG members.
+
+Changes to WG membership should be posted in the agenda, and may be
+suggested as any other agenda item (see "WG Meetings" below).
+
+If an addition or removal is proposed during a meeting, and the full
+WG is not in attendance to participate, then the addition or removal
+is added to the agenda for the subsequent meeting. This is to ensure
+that all members are given the opportunity to participate in all
+membership decisions. If a WG member is unable to attend a meeting
+where a planned membership decision is being made, then their consent
+is assumed.
+
+No more than 1/3 of the WG members may be affiliated with the same
+employer. If removal or resignation of a WG member, or a change of
+employment by a WG member, creates a situation where more than 1/3 of
+the WG membership shares an employer, then the situation must be
+immediately remedied by the resignation or removal of one or more WG
+members affiliated with the over-represented employer(s).
+
+### WG Meetings
+
+The WG meets occasionally on a Google Hangout On Air. A designated moderator
+approved by the WG runs the meeting. Each meeting should be
+published to YouTube.
+
+Items are added to the WG agenda that are considered contentious or
+are modifications of governance, contribution policy, WG membership,
+or release process.
+
+The intention of the agenda is not to approve or review all patches;
+that should happen continuously on GitHub and be handled by the larger
+group of Collaborators.
+
+Any community member or contributor can ask that something be added to
+the next meeting's agenda by logging a GitHub Issue. Any Collaborator,
+WG member or the moderator can add the item to the agenda by adding
+the ***WG-agenda*** tag to the issue.
+
+Prior to each WG meeting the moderator will share the Agenda with
+members of the WG. WG members can add any items they like to the
+agenda at the beginning of each meeting. The moderator and the WG
+cannot veto or remove items.
+
+The WG may invite persons or representatives from certain projects to
+participate in a non-voting capacity.
+
+The moderator is responsible for summarizing the discussion of each
+agenda item and sends it as a pull request after the meeting.
+
+### Consensus Seeking Process
+
+The WG follows a
+[Consensus
+Seeking](http://en.wikipedia.org/wiki/Consensus-seeking_decision-making)
+decision-making model.
+
+When an agenda item has appeared to reach a consensus the moderator
+will ask "Does anyone object?" as a final call for dissent from the
+consensus.
+
+If an agenda item cannot reach a consensus a WG member can call for
+either a closing vote or a vote to table the issue to the next
+meeting. The call for a vote must be seconded by a majority of the WG
+or else the discussion will continue. Simple majority wins.
+
+Note that changes to WG membership require a majority consensus. See
+"WG Membership" above.

+***Node.js core streams for userland*** [](https://travis-ci.com/nodejs/readable-stream)
+
+
+[](https://nodei.co/npm/readable-stream/)
+[](https://nodei.co/npm/readable-stream/)
+
+
+[](https://saucelabs.com/u/readabe-stream)
+
+```bash
+npm install --save readable-stream
+```
+
+This package is a mirror of the streams implementations in Node.js.
+
+Full documentation may be found on the [Node.js website](https://nodejs.org/dist/v10.19.0/docs/api/stream.html).
+
+If you want to guarantee a stable streams base, regardless of what version of
+Node you, or the users of your libraries are using, use **readable-stream** *only* and avoid the *"stream"* module in Node-core, for background see [this blogpost](http://r.va.gg/2014/06/why-i-dont-use-nodes-core-stream-module.html).
+
+As of version 2.0.0 **readable-stream** uses semantic versioning.
+
+## Version 3.x.x
+
+v3.x.x of `readable-stream` is a cut from Node 10. This version supports Node 6, 8, and 10, as well as evergreen browsers, IE 11 and latest Safari. The breaking changes introduced by v3 are composed by the combined breaking changes in [Node v9](https://nodejs.org/en/blog/release/v9.0.0/) and [Node v10](https://nodejs.org/en/blog/release/v10.0.0/), as follows:
+
+1. Error codes: https://github.com/nodejs/node/pull/13310,
+ https://github.com/nodejs/node/pull/13291,
+ https://github.com/nodejs/node/pull/16589,
+ https://github.com/nodejs/node/pull/15042,
+ https://github.com/nodejs/node/pull/15665,
+ https://github.com/nodejs/readable-stream/pull/344
+2. 'readable' have precedence over flowing
+ https://github.com/nodejs/node/pull/18994
+3. make virtual methods errors consistent
+ https://github.com/nodejs/node/pull/18813
+4. updated streams error handling
+ https://github.com/nodejs/node/pull/18438
+5. writable.end should return this.
+ https://github.com/nodejs/node/pull/18780
+6. readable continues to read when push('')
+ https://github.com/nodejs/node/pull/18211
+7. add custom inspect to BufferList
+ https://github.com/nodejs/node/pull/17907
+8. always defer 'readable' with nextTick
+ https://github.com/nodejs/node/pull/17979
+
+## Version 2.x.x
+v2.x.x of `readable-stream` is a cut of the stream module from Node 8 (there have been no semver-major changes from Node 4 to 8). This version supports all Node.js versions from 0.8, as well as evergreen browsers and IE 10 & 11.

+
+# Usage
+
+You can swap your `require('stream')` with `require('readable-stream')`
+without any changes, if you are just using one of the main classes and
+functions.
+
+```js
+const {
+ Readable,
+ Writable,
+ Transform,
+ Duplex,
+ pipeline,
+ finished
+} = require('readable-stream')
+````
+
+Note that `require('stream')` will return `Stream`, while
+`require('readable-stream')` will return `Readable`. We discourage using
+whatever is exported directly, but rather use one of the properties as
+shown in the example above.
+
+# Streams Working Group
+
+`readable-stream` is maintained by the Streams Working Group, which
+oversees the development and maintenance of the Streams API within
+Node.js. The responsibilities of the Streams Working Group include:
+
+* Addressing stream issues on the Node.js issue tracker.
+* Authoring and editing stream documentation within the Node.js project.
+* Reviewing changes to stream subclasses within the Node.js project.
+* Redirecting changes to streams from the Node.js project to this
+ project.
+* Assisting in the implementation of stream providers within Node.js.
+* Recommending versions of `readable-stream` to be included in Node.js.
+* Messaging about the future of streams to give the community advance
+ notice of changes.

+// a transform stream is a readable/writable stream where you do
+// something with the data. Sometimes it's called a "filter",
+// but that's not a great name for it, since that implies a thing where
+// some bits pass through, and others are simply ignored. (That would
+// be a valid example of a transform, of course.)
+//
+// While the output is causally related to the input, it's not a
+// necessarily symmetric or synchronous transformation. For example,
+// a zlib stream might take multiple plain-text writes(), and then
+// emit a single compressed chunk some time in the future.
+//
+// Here's how this works:
+//
+// The Transform stream has all the aspects of the readable and writable
+// stream classes. When you write(chunk), that calls _write(chunk,cb)
+// internally, and returns false if there's a lot of pending writes
+// buffered up. When you call read(), that calls _read(n) until
+// there's enough pending readable data buffered up.
+//
+// In a transform stream, the written data is placed in a buffer. When
+// _read(n) is called, it transforms the queued up data, calling the
+// buffered _write cb's as it consumes chunks. If consuming a single
+// written chunk would result in multiple output chunks, then the first
+// outputted bit calls the readcb, and subsequent chunks just go into
+// the read buffer, and will cause it to emit 'readable' if necessary.
+//
+// This way, back-pressure is actually determined by the reading side,
+// since _read has to be called to start processing a new chunk. However,
+// a pathological inflate type of transform can cause excessive buffering
+// here. For example, imagine a stream where every byte of input is
+// interpreted as an integer from 0-255, and then results in that many
+// bytes of output. Writing the 4 bytes {ff,ff,ff,ff} would result in
+// 1kb of data being output. In this case, you could write a very small
+// amount of input, and end up with a very large amount of output. In
+// such a pathological inflating mechanism, there'd be no way to tell
+// the system to stop doing the transform. A single 4MB write could
+// cause the system to run out of memory.
+//
+// However, even in such a pathological case, only a single written chunk
+// would be consumed, and then the rest would wait (un-transformed) until
+// the results of the previous transformed chunk were consumed.

+[saucelabs-url]: https://saucelabs.com/u/buffer
+
+With [browserify](http://browserify.org), simply `require('buffer')` or use the `Buffer` global and you will get this module.
+
+The goal is to provide an API that is 100% identical to
+[node's Buffer API](https://nodejs.org/api/buffer.html). Read the
+[official docs](https://nodejs.org/api/buffer.html) for the full list of properties,
+instance methods, and class methods that are supported.
+
+## features
+
+- Manipulate binary data like a boss, in all browsers!
+- Super fast. Backed by Typed Arrays (`Uint8Array`/`ArrayBuffer`, not `Object`)
+- Extremely small bundle size (**6.75KB minified + gzipped**, 51.9KB with comments)
+- Excellent browser support (Chrome, Firefox, Edge, Safari 9+, IE 11, iOS 9+, Android, etc.)
+- Preserves Node API exactly, with one minor difference (see below)
+- Square-bracket `buf[4]` notation works!
+- Does not modify any browser prototypes or put anything on `window`
+- Comprehensive test suite (including all buffer tests from node.js core)
+
+## install
+
+To use this module directly (without browserify), install it:
+
+```bash
+npm install buffer
+```
+
+This module was previously called **native-buffer-browserify**, but please use **buffer**
+from now on.
+
+If you do not use a bundler, you can use the [standalone script](https://bundle.run/buffer).
+
+## usage
+
+The module's API is identical to node's `Buffer` API. Read the
+[official docs](https://nodejs.org/api/buffer.html) for the full list of properties,
+instance methods, and class methods that are supported.
+
+As mentioned above, `require('buffer')` or use the `Buffer` global with
+[browserify](http://browserify.org) and this module will automatically be included
+in your bundle. Almost any npm module will work in the browser, even if it assumes that
+the node `Buffer` API will be available.
+
+To depend on this module explicitly (without browserify), require it like this:
+
+```js
+var Buffer = require('buffer/').Buffer // note: the trailing slash is important!
+```
+
+To require this module explicitly, use `require('buffer/')` which tells the node.js module
+lookup algorithm (also used by browserify) to use the **npm module** named `buffer`
+instead of the **node.js core** module named `buffer`!
+
+
+## how does it work?
+
+The Buffer constructor returns instances of `Uint8Array` that have their prototype
+changed to `Buffer.prototype`. Furthermore, `Buffer` is a subclass of `Uint8Array`,
+so the returned instances will have all the node `Buffer` methods and the
+`Uint8Array` methods. Square bracket notation works as expected -- it returns a
+single octet.
+
+The `Uint8Array` prototype remains unmodified.
+
+
+## tracking the latest node api
+
+This module tracks the Buffer API in the latest (unstable) version of node.js. The Buffer
+API is considered **stable** in the
+[node stability index](https://nodejs.org/docs/latest/api/documentation.html#documentation_stability_index),
+so it is unlikely that there will ever be breaking changes.
+Nonetheless, when/if the Buffer API changes in node, this module's API will change
+accordingly.
+
+## related packages
+
+- [`buffer-reverse`](https://www.npmjs.com/package/buffer-reverse) - Reverse a buffer
+- [`buffer-xor`](https://www.npmjs.com/package/buffer-xor) - Bitwise xor a buffer
+- [`is-buffer`](https://www.npmjs.com/package/is-buffer) - Determine if an object is a Buffer without including the whole `Buffer` package
+
+## conversion packages
+
+### convert typed array to buffer
+
+Use [`typedarray-to-buffer`](https://www.npmjs.com/package/typedarray-to-buffer) to convert any kind of typed array to a `Buffer`. Does not perform a copy, so it's super fast.
+
+### convert buffer to typed array
+
+`Buffer` is a subclass of `Uint8Array` (which is a typed array). So there is no need to explicitly convert to typed array. Just use the buffer as a `Uint8Array`.
+
+### convert blob to buffer
+
+Use [`blob-to-buffer`](https://www.npmjs.com/package/blob-to-buffer) to convert a `Blob` to a `Buffer`.
+
+### convert buffer to blob
+
+To convert a `Buffer` to a `Blob`, use the `Blob` constructor:
+
+```js
+var blob = new Blob([ buffer ])
+```
+
+Optionally, specify a mimetype:
+
+```js
+var blob = new Blob([ buffer ], { type: 'text/html' })
+```
+
+### convert arraybuffer to buffer
+
+To convert an `ArrayBuffer` to a `Buffer`, use the `Buffer.from` function. Does not perform a copy, so it's super fast.
+
+```js
+var buffer = Buffer.from(arrayBuffer)
+```
+
+### convert buffer to arraybuffer
+
+To convert a `Buffer` to an `ArrayBuffer`, use the `.buffer` property (which is present on all `Uint8Array` objects):
+
+```js
+var arrayBuffer = buffer.buffer.slice(
+ buffer.byteOffset, buffer.byteOffset + buffer.byteLength
+)
+```
+
+Alternatively, use the [`to-arraybuffer`](https://www.npmjs.com/package/to-arraybuffer) module.
+
+## performance
+
+See perf tests in `/perf`.
+
+`BrowserBuffer` is the browser `buffer` module (this repo). `Uint8Array` is included as a
+sanity check (since `BrowserBuffer` uses `Uint8Array` under the hood, `Uint8Array` will
+always be at least a bit faster). Finally, `NodeBuffer` is the node.js buffer module,
+which is included to compare against.
+
+NOTE: Performance has improved since these benchmarks were taken. PR welcome to update the README.

+
+## Testing the project
+
+First, install the project:
+
+ npm install
+
+Then, to run tests in Node.js, run:
+
+ npm run test-node
+
+To test locally in a browser, you can run:
+
+ npm run test-browser-es5-local # For ES5 browsers that don't support ES6
+ npm run test-browser-es6-local # For ES6 compliant browsers
+
+This will print out a URL that you can then open in a browser to run the tests, using [airtap](https://www.npmjs.com/package/airtap).
+
+To run automated browser tests using Saucelabs, ensure that your `SAUCE_USERNAME` and `SAUCE_ACCESS_KEY` environment variables are set, then run:
+
+ npm test
+
+This is what's run in Travis, to check against various browsers. The list of browsers is kept in the `bin/airtap-es5.yml` and `bin/airtap-es6.yml` files.
+
+## JavaScript Standard Style
+
+This module uses [JavaScript Standard Style](https://github.com/feross/standard).
+
+[](https://github.com/feross/standard)
+
+To test that the code conforms to the style, `npm install` and run:
+
+ ./node_modules/.bin/standard

+# Console Control Strings
+
+A library of cross-platform tested terminal/console command strings for
+doing things like color and cursor positioning. This is a subset of both
+ansi and vt100. All control codes included work on both Windows & Unix-like
+OSes, except where noted.
+
+## Usage
+
+```js
+var consoleControl = require('console-control-strings')
+
+console.log(consoleControl.color('blue','bgRed', 'bold') + 'hi there' + consoleControl.color('reset'))
+process.stdout.write(consoleControl.goto(75, 10))
+```
+
+## Why Another?
+
+There are tons of libraries similar to this one. I wanted one that was:
+
+1. Very clear about compatibility goals.
+2. Could emit, for instance, a start color code without an end one.
+3. Returned strings w/o writing to streams.
+4. Was not weighed down with other unrelated baggage.
+
+## Functions
+
+### var code = consoleControl.up(_num = 1_)
+
+Returns the escape sequence to move _num_ lines up.
+
+### var code = consoleControl.down(_num = 1_)
+
+Returns the escape sequence to move _num_ lines down.
+
+### var code = consoleControl.forward(_num = 1_)
+
+Returns the escape sequence to move _num_ lines righ.
+
+### var code = consoleControl.back(_num = 1_)
+
+Returns the escape sequence to move _num_ lines left.
+
+### var code = consoleControl.nextLine(_num = 1_)
+
+Returns the escape sequence to move _num_ lines down and to the beginning of
+the line.
+
+### var code = consoleControl.previousLine(_num = 1_)
+
+Returns the escape sequence to move _num_ lines up and to the beginning of
+the line.
+
+### var code = consoleControl.eraseData()
+
+Returns the escape sequence to erase everything from the current cursor
+position to the bottom right of the screen. This is line based, so it
+erases the remainder of the current line and all following lines.
+
+### var code = consoleControl.eraseLine()
+
+Returns the escape sequence to erase to the end of the current line.
+
+### var code = consoleControl.goto(_x_, _y_)
+
+Returns the escape sequence to move the cursor to the designated position.
+Note that the origin is _1, 1_ not _0, 0_.
+
+### var code = consoleControl.gotoSOL()
+
+Returns the escape sequence to move the cursor to the beginning of the
+current line. (That is, it returns a carriage return, `\r`.)
+
+### var code = consoleControl.beep()
+
+Returns the escape sequence to cause the termianl to beep. (That is, it
+returns unicode character `\x0007`, a Control-G.)
+
+### var code = consoleControl.hideCursor()
+
+Returns the escape sequence to hide the cursor.
+
+### var code = consoleControl.showCursor()
+
+Returns the escape sequence to show the cursor.
+
+### var code = consoleControl.color(_colors = []_)
+
+### var code = consoleControl.color(_color1_, _color2_, _…_, _colorn_)
+
+Returns the escape sequence to set the current terminal display attributes
+(mostly colors). Arguments can either be a list of attributes or an array
+of attributes. The difference between passing in an array or list of colors
+and calling `.color` separately for each one, is that in the former case a
+single escape sequence will be produced where as in the latter each change
+will have its own distinct escape sequence. Each attribute can be one of:
+
+* Reset:
+ * **reset** – Reset all attributes to the terminal default.
+* Styles:
+ * **bold** – Display text as bold. In some terminals this means using a
+ bold font, in others this means changing the color. In some it means
+ both.
+ * **italic** – Display text as italic. This is not available in most Windows terminals.
+ * **underline** – Underline text. This is not available in most Windows Terminals.
+ * **inverse** – Invert the foreground and background colors.
+ * **stopBold** – Do not display text as bold.
+ * **stopItalic** – Do not display text as italic.
+ * **stopUnderline** – Do not underline text.
+ * **stopInverse** – Do not invert foreground and background.
+* Colors:
+ * **white**
+ * **black**
+ * **blue**
+ * **cyan**
+ * **green**
+ * **magenta**
+ * **red**
+ * **yellow**
+ * **grey** / **brightBlack**
+ * **brightRed**
+ * **brightGreen**
+ * **brightYellow**
+ * **brightBlue**
+ * **brightMagenta**
+ * **brightCyan**
+ * **brightWhite**
+* Background Colors:
+ * **bgWhite**
+ * **bgBlack**
+ * **bgBlue**
+ * **bgCyan**
+ * **bgGreen**
+ * **bgMagenta**
+ * **bgRed**
+ * **bgYellow**
+ * **bgGrey** / **bgBrightBlack**
+ * **bgBrightRed**
+ * **bgBrightGreen**
+ * **bgBrightYellow**
+ * **bgBrightBlue**
+ * **bgBrightMagenta**
+ * **bgBrightCyan**
+ * **bgBrightWhite**

+
+A tiny JavaScript debugging utility modelled after Node.js core's debugging
+technique. Works in Node.js and web browsers.
+
+## Installation
+
+```bash
+$ npm install debug
+```
+
+## Usage
+
+`debug` exposes a function; simply pass this function the name of your module, and it will return a decorated version of `console.error` for you to pass debug statements to. This will allow you to toggle the debug output for different parts of your module as well as the module as a whole.
+
+Example [_app.js_](./examples/node/app.js):
+
+```js
+var debug = require('debug')('http')
+ , http = require('http')
+ , name = 'My App';
+
+// fake app
+
+debug('booting %o', name);
+
+http.createServer(function(req, res){
+ debug(req.method + ' ' + req.url);
+ res.end('hello\n');
+}).listen(3000, function(){
+ debug('listening');
+});
+
+// fake worker of some kind
+
+require('./worker');
+```
+
+Example [_worker.js_](./examples/node/worker.js):
+
+```js
+var a = require('debug')('worker:a')
+ , b = require('debug')('worker:b');
+
+function work() {
+ a('doing lots of uninteresting work');
+ setTimeout(work, Math.random() * 1000);
+}
+
+work();
+
+function workb() {
+ b('doing some work');
+ setTimeout(workb, Math.random() * 2000);
+}
+
+workb();
+```
+
+The `DEBUG` environment variable is then used to enable these based on space or
+comma-delimited names.
+
+Here are some examples:
+
+<img width="647" alt="screen shot 2017-08-08 at 12 53 04 pm" src="https://user-images.githubusercontent.com/71256/29091703-a6302cdc-7c38-11e7-8304-7c0b3bc600cd.png">
+<img width="647" alt="screen shot 2017-08-08 at 12 53 38 pm" src="https://user-images.githubusercontent.com/71256/29091700-a62a6888-7c38-11e7-800b-db911291ca2b.png">
+<img width="647" alt="screen shot 2017-08-08 at 12 53 25 pm" src="https://user-images.githubusercontent.com/71256/29091701-a62ea114-7c38-11e7-826a-2692bedca740.png">
+
+#### Windows command prompt notes
+
+##### CMD
+
+On Windows the environment variable is set using the `set` command.
+
+```cmd
+set DEBUG=*,-not_this
+```
+
+Example:
+
+```cmd
+set DEBUG=* & node app.js
+```
+
+##### PowerShell (VS Code default)
+
+PowerShell uses different syntax to set environment variables.
+
+```cmd
+$env:DEBUG = "*,-not_this"
+```
+
+Example:
+
+```cmd
+$env:DEBUG='app';node app.js
+```
+
+Then, run the program to be debugged as usual.
+
+npm script example:
+```js
+ "windowsDebug": "@powershell -Command $env:DEBUG='*';node app.js",
+```
+
+## Namespace Colors
+
+Every debug instance has a color generated for it based on its namespace name.
+This helps when visually parsing the debug output to identify which debug instance
+a debug line belongs to.
+
+#### Node.js
+
+In Node.js, colors are enabled when stderr is a TTY. You also _should_ install
+the [`supports-color`](https://npmjs.org/supports-color) module alongside debug,
+otherwise debug will only use a small handful of basic colors.
+
+<img width="521" src="https://user-images.githubusercontent.com/71256/29092181-47f6a9e6-7c3a-11e7-9a14-1928d8a711cd.png">
+
+#### Web Browser
+
+Colors are also enabled on "Web Inspectors" that understand the `%c` formatting
+option. These are WebKit web inspectors, Firefox ([since version
+31](https://hacks.mozilla.org/2014/05/editable-box-model-multiple-selection-sublime-text-keys-much-more-firefox-developer-tools-episode-31/))
+and the Firebug plugin for Firefox (any version).
+
+<img width="524" src="https://user-images.githubusercontent.com/71256/29092033-b65f9f2e-7c39-11e7-8e32-f6f0d8e865c1.png">
+
+
+## Millisecond diff
+
+When actively developing an application it can be useful to see when the time spent between one `debug()` call and the next. Suppose for example you invoke `debug()` before requesting a resource, and after as well, the "+NNNms" will show you how much time was spent between calls.
+
+<img width="647" src="https://user-images.githubusercontent.com/71256/29091486-fa38524c-7c37-11e7-895f-e7ec8e1039b6.png">
+
+When stdout is not a TTY, `Date#toISOString()` is used, making it more useful for logging the debug information as shown below:
+
+<img width="647" src="https://user-images.githubusercontent.com/71256/29091956-6bd78372-7c39-11e7-8c55-c948396d6edd.png">
+
+
+## Conventions
+
+If you're using this in one or more of your libraries, you _should_ use the name of your library so that developers may toggle debugging as desired without guessing names. If you have more than one debuggers you _should_ prefix them with your library name and use ":" to separate features. For example "bodyParser" from Connect would then be "connect:bodyParser". If you append a "*" to the end of your name, it will always be enabled regardless of the setting of the DEBUG environment variable. You can then use it for normal output as well as debug output.
+
+## Wildcards
+
+The `*` character may be used as a wildcard. Suppose for example your library has
+debuggers named "connect:bodyParser", "connect:compress", "connect:session",
+instead of listing all three with
+`DEBUG=connect:bodyParser,connect:compress,connect:session`, you may simply do
+`DEBUG=connect:*`, or to run everything using this module simply use `DEBUG=*`.
+
+You can also exclude specific debuggers by prefixing them with a "-" character.
+For example, `DEBUG=*,-connect:*` would include all debuggers except those
+starting with "connect:".
+
+## Environment Variables
+
+When running through Node.js, you can set a few environment variables that will
+change the behavior of the debug logging:
+
+| Name | Purpose |
+|-----------|-------------------------------------------------|
+| `DEBUG` | Enables/disables specific debugging namespaces. |
+| `DEBUG_HIDE_DATE` | Hide date from debug output (non-TTY). |
+| `DEBUG_COLORS`| Whether or not to use colors in the debug output. |
+| `DEBUG_DEPTH` | Object inspection depth. |
+| `DEBUG_SHOW_HIDDEN` | Shows hidden properties on inspected objects. |
+
+
+__Note:__ The environment variables beginning with `DEBUG_` end up being
+converted into an Options object that gets used with `%o`/`%O` formatters.
+See the Node.js documentation for
+[`util.inspect()`](https://nodejs.org/api/util.html#util_util_inspect_object_options)
+for the complete list.
+
+## Formatters
+
+Debug uses [printf-style](https://wikipedia.org/wiki/Printf_format_string) formatting.
+Below are the officially supported formatters:
+
+| Formatter | Representation |
+|-----------|----------------|
+| `%O` | Pretty-print an Object on multiple lines. |
+| `%o` | Pretty-print an Object all on a single line. |
+| `%s` | String. |
+| `%d` | Number (both integer and float). |
+| `%j` | JSON. Replaced with the string '[Circular]' if the argument contains circular references. |
+| `%%` | Single percent sign ('%'). This does not consume an argument. |
+
+
+### Custom formatters
+
+You can add custom formatters by extending the `debug.formatters` object.
+For example, if you wanted to add support for rendering a Buffer as hex with
+`%h`, you could do something like:
+
+```js
+const createDebug = require('debug')
+createDebug.formatters.h = (v) => {
+ return v.toString('hex')
+}
+
+// …elsewhere
+const debug = createDebug('foo')
+debug('this is hex: %h', new Buffer('hello world'))
+// foo this is hex: 68656c6c6f20776f726c6421 +0ms
+```
+
+
+## Browser Support
+
+You can build a browser-ready script using [browserify](https://github.com/substack/node-browserify),
+or just use the [browserify-as-a-service](https://wzrd.in/) [build](https://wzrd.in/standalone/debug@latest),
+if you don't want to build it yourself.
+
+Debug's enable state is currently persisted by `localStorage`.
+Consider the situation shown below where you have `worker:a` and `worker:b`,
+and wish to debug both. You can enable this using `localStorage.debug`:
+
+```js
+localStorage.debug = 'worker:*'
+```
+
+And then refresh the page.
+
+```js
+a = debug('worker:a');
+b = debug('worker:b');
+
+setInterval(function(){
+ a('doing some work');
+}, 1000);
+
+setInterval(function(){
+ b('doing some work');
+}, 1200);
+```
+
+
+## Output streams
+
+ By default `debug` will log to stderr, however this can be configured per-namespace by overriding the `log` method:
+
+Example [_stdout.js_](./examples/node/stdout.js):
+
+```js
+var debug = require('debug');
+var error = debug('app:error');
+
+// by default stderr is used
+error('goes to stderr!');
+
+var log = debug('app:log');
+// set this namespace to log via console.log
+log.log = console.log.bind(console); // don't forget to bind to console!
+log('goes to stdout');
+error('still goes to stderr!');
+
+// set all output to go via console.info
+// overrides all per-namespace log settings
+debug.log = console.info.bind(console);
+error('now goes to stdout via console.info');
+log('still goes to stdout, but via console.info now');
+```
+
+## Extend
+You can simply extend debugger
+```js
+const log = require('debug')('auth');
+
+//creates new debug instance with extended namespace
+const logSign = log.extend('sign');
+const logLogin = log.extend('login');
+
+log('hello'); // auth hello
+logSign('hello'); //auth:sign hello
+logLogin('hello'); //auth:login hello
+```
+
+## Set dynamically
+
+You can also enable debug dynamically by calling the `enable()` method :
+
+```js
+let debug = require('debug');
+
+console.log(1, debug.enabled('test'));
+
+debug.enable('test');
+console.log(2, debug.enabled('test'));
+
+debug.disable();
+console.log(3, debug.enabled('test'));
+
+```
+
+print :
+```
+1 false
+2 true
+3 false
+```
+
+Usage :
+`enable(namespaces)`
+`namespaces` can include modes separated by a colon and wildcards.
+
+Note that calling `enable()` completely overrides previously set DEBUG variable :
+
+```
+$ DEBUG=foo node -e 'var dbg = require("debug"); dbg.enable("bar"); console.log(dbg.enabled("foo"))'
+=> false
+```
+
+`disable()`
+
+Will disable all namespaces. The functions returns the namespaces currently
+enabled (and skipped). This can be useful if you want to disable debugging
+temporarily without knowing what was enabled to begin with.
+
+For example:
+
+```js
+let debug = require('debug');
+debug.enable('foo:*,-foo:bar');
+let namespaces = debug.disable();
+debug.enable(namespaces);
+```
+
+Note: There is no guarantee that the string will be identical to the initial
+enable string, but semantically they will be identical.
+
+## Checking whether a debug target is enabled
+
+After you've created a debug instance, you can determine whether or not it is
+enabled by checking the `enabled` property:
+
+```javascript
+const debug = require('debug')('http');
+
+if (debug.enabled) {
+ // do stuff...
+}
+```
+
+You can also manually toggle this property to force the debug instance to be
+enabled or disabled.

+Changelog
+=========
+
+v0.6.0
+------
+
+- Updated "devDependencies" versions to fix vulnerability alerts
+- Dropped support of io.js and node.js v0.12.x and lower since new versions of
+ "devDependencies" couldn't work with those old node.js versions
+ (minimal supported version of node.js now is v4.0.0)
+
+v0.5.1
+------
+
+- Fix prototype pollution vulnerability (thanks to @mwakerman for the PR)
+- Avoid using deprecated Buffer API (thanks to @ChALkeR for the PR)
+
+v0.5.0
+------
+
+- Auto-testing provided by Travis CI;
+- Support older Node.JS versions (`v0.11.x` and `v0.10.x`);
+- Removed tests files from npm package.
+
+v0.4.2
+------
+
+- Fix for `null` as an argument.
+
+v0.4.1
+------
+
+- Removed test code from <b>npm</b> package
+ ([see pull request #21](https://github.com/unclechu/node-deep-extend/pull/21));
+- Increased minimal version of Node from `0.4.0` to `0.12.0`
+ (because can't run tests on lesser version anyway).
+
+v0.4.0
+------
+
+- **WARNING!** Broken backward compatibility with `v0.3.x`;
+- Fixed bug with extending arrays instead of cloning;
+- Deep cloning for arrays;
+- Check for own property;
+- Fixed some documentation issues;
+- Strict JS mode.

+# delegates
+
+ Node method and accessor delegation utilty.
+
+## Installation
+
+```
+$ npm install delegates
+```
+
+## Example
+
+```js
+var delegate = require('delegates');
+
+...
+
+delegate(proto, 'request')
+ .method('acceptsLanguages')
+ .method('acceptsEncodings')
+ .method('acceptsCharsets')
+ .method('accepts')
+ .method('is')
+ .access('querystring')
+ .access('idempotent')
+ .access('socket')
+ .access('length')
+ .access('query')
+ .access('search')
+ .access('status')
+ .access('method')
+ .access('path')
+ .access('body')
+ .access('host')
+ .access('url')
+ .getter('subdomains')
+ .getter('protocol')
+ .getter('header')
+ .getter('stale')
+ .getter('fresh')
+ .getter('secure')
+ .getter('ips')
+ .getter('ip')
+```
+
+# API
+
+## Delegate(proto, prop)
+
+Creates a delegator instance used to configure using the `prop` on the given
+`proto` object. (which is usually a prototype)
+
+## Delegate#method(name)
+
+Allows the given method `name` to be accessed on the host.
+
+## Delegate#getter(name)
+
+Creates a "getter" for the property with the given `name` on the delegated
+object.
+
+## Delegate#setter(name)
+
+Creates a "setter" for the property with the given `name` on the delegated
+object.
+
+## Delegate#access(name)
+
+Creates an "accessor" (ie: both getter *and* setter) for the property with the
+given `name` on the delegated object.
+
+## Delegate#fluent(name)
+
+A unique type of "accessor" that works for a "fluent" API. When called as a
+getter, the method returns the expected value. However, if the method is called
+with a value, it will return itself so it can be chained. For example:
+
+```js
+delegate(proto, 'request')
+ .fluent('query')
+
+// getter
+var q = request.query();
+
+// setter (chainable)
+request
+ .query({ a: 1 })
+ .query({ b: 2 });
+```

+# detect-libc
+
+Node.js module to detect the C standard library (libc) implementation
+family and version in use on a given Linux system.
+
+Provides a value suitable for use with the `LIBC` option of
+[prebuild](https://www.npmjs.com/package/prebuild),
+[prebuild-ci](https://www.npmjs.com/package/prebuild-ci) and
+[prebuild-install](https://www.npmjs.com/package/prebuild-install),
+therefore allowing build and provision of pre-compiled binaries
+for musl-based Linux e.g. Alpine as well as glibc-based.
+
+Currently supports libc detection of `glibc` and `musl`.
+
+## Install
+
+```sh
+npm install detect-libc
+```
+
+## Usage
+
+### API
+
+```js
+const { GLIBC, MUSL, family, version, isNonGlibcLinux } = require('detect-libc');
+```
+
+* `GLIBC` is a String containing the value "glibc" for comparison with `family`.
+* `MUSL` is a String containing the value "musl" for comparison with `family`.
+* `family` is a String representing the system libc family.
+* `version` is a String representing the system libc version number.
+* `isNonGlibcLinux` is a Boolean representing whether the system is a non-glibc Linux, e.g. Alpine.
+
+### detect-libc command line tool
+
+When run on a Linux system with a non-glibc libc,
+the child command will be run with the `LIBC` environment variable
+set to the relevant value.
+
+On all other platforms will run the child command as-is.
+
+The command line feature requires `spawnSync` provided by Node v0.12+.
+
+```sh
+detect-libc child-command
+```
+
+## Integrating with prebuild

+# end-of-stream
+
+A node module that calls a callback when a readable/writable/duplex stream has completed or failed.
+
+ npm install end-of-stream
+
+[](https://travis-ci.org/mafintosh/end-of-stream)
+
+## Usage
+
+Simply pass a stream and a callback to the `eos`.
+Both legacy streams, streams2 and stream3 are supported.
+
+``` js
+var eos = require('end-of-stream');
+
+eos(readableStream, function(err) {
+ // this will be set to the stream instance
+ if (err) return console.log('stream had an error or closed early');
+ console.log('stream has ended', this === readableStream);
+});
+
+eos(writableStream, function(err) {
+ if (err) return console.log('stream had an error or closed early');
+ console.log('stream has finished', this === writableStream);
+});
+
+eos(duplexStream, function(err) {
+ if (err) return console.log('stream had an error or closed early');
+ console.log('stream has ended and finished', this === duplexStream);
+});
+
+eos(duplexStream, {readable:false}, function(err) {
+ if (err) return console.log('stream had an error or closed early');
+ console.log('stream has finished but might still be readable');
+});
+
+eos(duplexStream, {writable:false}, function(err) {
+ if (err) return console.log('stream had an error or closed early');
+ console.log('stream has ended but might still be writable');
+});
+
+eos(readableStream, {error:false}, function(err) {
+ // do not treat emit('error', err) as a end-of-stream
+});
+```

+
+[](https://www.npmjs.com/package/expand-template)
+
+[](https://travis-ci.org/ralphtheninja/expand-template)
+[](https://standardjs.com)
+
+## Install
+
+```
+$ npm i expand-template -S
+```
+
+## Usage
+
+Default functionality expands templates using `{}` as separators for string placeholders.
+
+```js
+var expand = require('expand-template')()
+var template = '{foo}/{foo}/{bar}/{bar}'
+console.log(expand(template, {
+ foo: 'BAR',
+ bar: 'FOO'
+}))
+// -> BAR/BAR/FOO/FOO
+```
+
+Custom separators:
+
+```js
+var expand = require('expand-template')({ sep: '[]' })
+var template = '[foo]/[foo]/[bar]/[bar]'
+console.log(expand(template, {
+ foo: 'BAR',
+ bar: 'FOO'
+}))
+// -> BAR/BAR/FOO/FOO
+```

+file-uri-to-path
+================
+### Convert a `file:` URI to a file path
+[](https://travis-ci.org/TooTallNate/file-uri-to-path)
+
+Accepts a `file:` URI and returns a regular file path suitable for use with the
+`fs` module functions.
+
+
+Installation
+------------
+
+Install with `npm`:
+
+``` bash
+$ npm install file-uri-to-path
+```
+
+
+Example
+-------
+
+``` js
+var uri2path = require('file-uri-to-path');
+
+uri2path('file://localhost/c|/WINDOWS/clock.avi');
+// "c:\\WINDOWS\\clock.avi"
+
+uri2path('file:///c|/WINDOWS/clock.avi');
+// "c:\\WINDOWS\\clock.avi"
+
+uri2path('file://localhost/c:/WINDOWS/clock.avi');
+// "c:\\WINDOWS\\clock.avi"
+
+uri2path('file://hostname/path/to/the%20file.txt');
+// "\\\\hostname\\path\\to\\the file.txt"
+
+uri2path('file:///c:/path/to/the%20file.txt');
+// "c:\\path\\to\\the file.txt"
+```

+# fs-constants
+
+Small module that allows you to get the fs constants across
+Node and the browser.
+
+```
+npm install fs-constants
+```
+
+Previously you would use `require('constants')` for this in node but that has been
+deprecated and changed to `require('fs').constants` which does not browserify.
+
+This module uses `require('constants')` in the browser and `require('fs').constants` in node to work around this
+
+
+## Usage
+
+``` js
+var constants = require('fs-constants')
+
+console.log('constants:', constants)
+```

@@ -0,0 +1,160 @@
+### v2.7.4
+
+* Reset colors prior to ending a line, to eliminate flicker when a line
+ is trucated between start and end color sequences.
+
+### v2.7.3
+
+* Only create our onExit handler when we're enabled and remove it when we're
+ disabled. This stops us from creating multiple onExit handlers when
+ multiple gauge objects are being used.
+* Fix bug where if a theme name were given instead of a theme object, it
+ would crash.
+* Remove supports-color because it's not actually used. Uhm. Yes, I just
+ updated it. >.>
+
+### v2.7.2
+
+* Use supports-color instead of has-color (as the module has been renamed)
+
+### v2.7.1
+
+* Bug fix: Calls to show/pulse while the progress bar is disabled should still
+ update our internal representation of what would be shown should it be enabled.
+
+### v2.7.0
+
+* New feature: Add new `isEnabled` method to allow introspection of the gauge's
+ "enabledness" as controlled by `.enable()` and `.disable()`.
+
+### v2.6.0
+
+* Bug fix: Don't run the code associated with `enable`/`disable` if the gauge
+ is already enabled or disabled respectively. This prevents leaking event
+ listeners, amongst other weirdness.
+* New feature: Template items can have default values that will be used if no
+ value was otherwise passed in.
+
+### v2.5.3
+
+* Default to `enabled` only if we have a tty. Users can always override
+ this by passing in the `enabled` option explicitly or by calling calling
+ `gauge.enable()`.
+
+### v2.5.2
+
+* Externalized `./console-strings.js` into `console-control-strings`.
+
+### v2.5.1
+
+* Update to `signal-exit@3.0.0`, which fixes a compatibility bug with the
+ node profiler.
+* [#39](https://github.com/iarna/gauge/pull/39) Fix tests on 0.10 and add
+ a missing devDependency. ([@helloyou2012](https://github.com/helloyou2012))
+
+### v2.5.0
+
+* Add way to programmatically fetch a list of theme names in a themeset
+ (`Themeset.getThemeNames`).
+
+### v2.4.0
+
+* Add support for setting themesets on existing gauge objects.
+* Add post-IO callback to `gauge.hide()` as it is somtetimes necessary when
+ your terminal is interleaving output from multiple filehandles (ie, stdout
+ & stderr).
+
+### v2.3.1
+
+* Fix a refactor bug in setTheme where it wasn't accepting the various types
+ of args it should.
+
+### v2.3.0
+
+#### FEATURES
+
+* Add setTemplate & setTheme back in.
+* Add support for named themes, you can now ask for things like 'colorASCII'
+ and 'brailleSpinner'. Of course, you can still pass in theme objects.
+ Additionally you can now pass in an object with `hasUnicode`, `hasColor` and
+ `platform` keys in order to override our guesses as to those values when
+ selecting a default theme from the themeset.
+* Make the output stream optional (it defaults to `process.stderr` now).
+* Add `setWriteTo(stream[, tty])` to change the output stream and,
+ optionally, tty.
+
+#### BUG FIXES & REFACTORING
+
+* Abort the display phase early if we're supposed to be hidden and we are.
+* Stop printing a bunch of spaces at the end of lines, since we're already
+ using an erase-to-end-of-line code anyway.
+* The unicode themes were missing the subsection separator.
+
+### v2.2.1
+
+* Fix image in readme
+
+### v2.2.0
+
+* All new themes API– reference themes by name and pass in custom themes and
+ themesets (themesets get platform support autodetection done on them to
+ select the best theme). Theme mixins let you add features to all existing
+ themes.
+* Much, much improved test coverage.
+
+### v2.1.0
+
+* Got rid of â–‘ in the default platform, noUnicode, hasColor theme. Thanks
+ to @yongtw123 for pointing out this had snuck in.
+* Fiddled with the demo output to make it easier to see the spinner spin. Also
+ added prints before each platforms test output.
+* I forgot to include `signal-exit` in our deps. <.< Thank you @KenanY for
+ finding this. Then I was lazy and made a new commit instead of using his
+ PR. Again, thank you for your patience @KenenY.
+* Drastically speed up travis testing.
+* Add a small javascript demo (demo.js) for showing off the various themes
+ (and testing them on diff platforms).
+* Change: The subsection separator from â„ and / (different chars) to >.
+* Fix crasher: A show or pulse without a label would cause the template renderer
+ to complain about a missing value.
+* New feature: Add the ability to disable the clean-up-on-exit behavior.
+ Not something I expect to be widely desirable, but important if you have
+ multiple distinct gauge instances in your app.
+* Use our own color support detection.
+ The `has-color` module proved too magic for my needs, making assumptions
+ as to which stream we write to and reading command line arguments.
+
+### v2.0.0
+
+This is a major rewrite of the internals. Externally there are fewer
+changes:
+
+* On node>0.8 gauge object now prints updates at a fixed rate. This means
+ that when you call `show` it may wate up to `updateInterval` ms before it
+ actually prints an update. You override this behavior with the
+ `fixedFramerate` option.
+* The gauge object now keeps the cursor hidden as long as it's enabled and
+ shown.
+* The constructor's arguments have changed, now it takes a mandatory output
+ stream and an optional options object. The stream no longer needs to be
+ an `ansi`ified stream, although it can be if you want (but we won't make
+ use of its special features).
+* Previously the gauge was disabled by default if `process.stdout` wasn't a
+ tty. Now it always defaults to enabled. If you want the previous
+ behavior set the `enabled` option to `process.stdout.isTTY`.
+* The constructor's options have changed– see the docs for details.
+* Themes are entirely different. If you were using a custom theme, or
+ referring to one directly (eg via `Gauge.unicode` or `Gauge.ascii`) then
+ you'll need to change your code. You can get the equivalent of the latter
+ with:
+ ```
+ var themes = require('gauge/themes')
+ var unicodeTheme = themes(true, true) // returns the color unicode theme for your platform
+ ```
+ The default themes no longer use any ambiguous width characters, so even
+ if you choose to display those as wide your progress bar should still
+ display correctly.
+* Templates are entirely different and if you were using a custom one, you
+ should consult the documentation to learn how to recreate it. If you were
+ using the default, be aware that it has changed and the result looks quite
+ a bit different.

+gauge
+=====
+
+A nearly stateless terminal based horizontal gauge / progress bar.
+
+```javascript
+var Gauge = require("gauge")
+
+var gauge = new Gauge()
+
+gauge.show("test", 0.20)
+
+gauge.pulse("this")
+
+gauge.hide()
+```
+
+
+
+
+### CHANGES FROM 1.x
+
+Gauge 2.x is breaking release, please see the [changelog] for details on
+what's changed if you were previously a user of this module.
+
+[changelog]: CHANGELOG.md
+
+### THE GAUGE CLASS
+
+This is the typical interface to the module– it provides a pretty
+fire-and-forget interface to displaying your status information.
+
+```
+var Gauge = require("gauge")
+
+var gauge = new Gauge([stream], [options])
+```
+
+* **stream** – *(optional, default STDERR)* A stream that progress bar
+ updates are to be written to. Gauge honors backpressure and will pause
+ most writing if it is indicated.
+* **options** – *(optional)* An option object.
+
+Constructs a new gauge. Gauges are drawn on a single line, and are not drawn
+if **stream** isn't a tty and a tty isn't explicitly provided.
+
+If **stream** is a terminal or if you pass in **tty** to **options** then we
+will detect terminal resizes and redraw to fit. We do this by watching for
+`resize` events on the tty. (To work around a bug in verisons of Node prior
+to 2.5.0, we watch for them on stdout if the tty is stderr.) Resizes to
+larger window sizes will be clean, but shrinking the window will always
+result in some cruft.
+
+**IMPORTANT:** If you prevously were passing in a non-tty stream but you still
+want output (for example, a stream wrapped by the `ansi` module) then you
+need to pass in the **tty** option below, as `gauge` needs access to
+the underlying tty in order to do things like terminal resizes and terminal
+width detection.
+
+The **options** object can have the following properties, all of which are
+optional:
+
+* **updateInterval**: How often gauge updates should be drawn, in miliseconds.
+* **fixedFramerate**: Defaults to false on node 0.8, true on everything
+ else. When this is true a timer is created to trigger once every
+ `updateInterval` ms, when false, updates are printed as soon as they come
+ in but updates more often than `updateInterval` are ignored. The reason
+ 0.8 doesn't have this set to true is that it can't `unref` its timer and
+ so it would stop your program from exiting– if you want to use this
+ feature with 0.8 just make sure you call `gauge.disable()` before you
+ expect your program to exit.
+* **themes**: A themeset to use when selecting the theme to use. Defaults
+ to `gauge/themes`, see the [themes] documentation for details.
+* **theme**: Select a theme for use, it can be a:
+ * Theme object, in which case the **themes** is not used.
+ * The name of a theme, which will be looked up in the current *themes*
+ object.
+ * A configuration object with any of `hasUnicode`, `hasColor` or
+ `platform` keys, which if wlll be used to override our guesses when making
+ a default theme selection.
+
+ If no theme is selected then a default is picked using a combination of our
+ best guesses at your OS, color support and unicode support.
+* **template**: Describes what you want your gauge to look like. The
+ default is what npm uses. Detailed [documentation] is later in this
+ document.
+* **hideCursor**: Defaults to true. If true, then the cursor will be hidden
+ while the gauge is displayed.
+* **tty**: The tty that you're ultimately writing to. Defaults to the same
+ as **stream**. This is used for detecting the width of the terminal and
+ resizes. The width used is `tty.columns - 1`. If no tty is available then
+ a width of `79` is assumed.
+* **enabled**: Defaults to true if `tty` is a TTY, false otherwise. If true
+ the gauge starts enabled. If disabled then all update commands are
+ ignored and no gauge will be printed until you call `.enable()`.
+* **Plumbing**: The class to use to actually generate the gauge for
+ printing. This defaults to `require('gauge/plumbing')` and ordinarly you
+ shouldn't need to override this.
+* **cleanupOnExit**: Defaults to true. Ordinarily we register an exit
+ handler to make sure your cursor is turned back on and the progress bar
+ erased when your process exits, even if you Ctrl-C out or otherwise exit
+ unexpectedly. You can disable this and it won't register the exit handler.
+
+[has-unicode]: https://www.npmjs.com/package/has-unicode
+[themes]: #themes
+[documentation]: #templates
+
+#### `gauge.show(section | status, [completed])`
+
+The first argument is either the section, the name of the current thing
+contributing to progress, or an object with keys like **section**,
+**subsection** & **completed** (or any others you have types for in a custom
+template). If you don't want to update or set any of these you can pass
+`null` and it will be ignored.
+
+The second argument is the percent completed as a value between 0 and 1.
+Without it, completion is just not updated. You'll also note that completion
+can be passed in as part of a status object as the first argument. If both
+it and the completed argument are passed in, the completed argument wins.
+
+#### `gauge.hide([cb])`
+
+Removes the gauge from the terminal. Optionally, callback `cb` after IO has
+had an opportunity to happen (currently this just means after `setImmediate`
+has called back.)
+
+It turns out this is important when you're pausing the progress bar on one
+filehandle and printing to another– otherwise (with a big enough print) node
+can end up printing the "end progress bar" bits to the progress bar filehandle
+while other stuff is printing to another filehandle. These getting interleaved
+can cause corruption in some terminals.
+
+#### `gauge.pulse([subsection])`
+
+* **subsection** – *(optional)* The specific thing that triggered this pulse
+
+Spins the spinner in the gauge to show output. If **subsection** is
+included then it will be combined with the last name passed to `gauge.show`.
+
+#### `gauge.disable()`
+
+Hides the gauge and ignores further calls to `show` or `pulse`.
+
+#### `gauge.enable()`
+
+Shows the gauge and resumes updating when `show` or `pulse` is called.
+
+#### `gauge.isEnabled()`
+
+Returns true if the gauge is enabled.
+
+#### `gauge.setThemeset(themes)`
+
+Change the themeset to select a theme from. The same as the `themes` option
+used in the constructor. The theme will be reselected from this themeset.
+
+#### `gauge.setTheme(theme)`
+
+Change the active theme, will be displayed with the next show or pulse. This can be:
+
+* Theme object, in which case the **themes** is not used.
+* The name of a theme, which will be looked up in the current *themes*
+ object.
+* A configuration object with any of `hasUnicode`, `hasColor` or
+ `platform` keys, which if wlll be used to override our guesses when making
+ a default theme selection.
+
+If no theme is selected then a default is picked using a combination of our
+best guesses at your OS, color support and unicode support.
+
+#### `gauge.setTemplate(template)`
+
+Change the active template, will be displayed with the next show or pulse
+
+### Tracking Completion
+
+If you have more than one thing going on that you want to track completion
+of, you may find the related [are-we-there-yet] helpful. It's `change`
+event can be wired up to the `show` method to get a more traditional
+progress bar interface.
+
+[are-we-there-yet]: https://www.npmjs.com/package/are-we-there-yet
+
+### THEMES
+
+```
+var themes = require('gauge/themes')
+
+// fetch the default color unicode theme for this platform
+var ourTheme = themes({hasUnicode: true, hasColor: true})
+
+// fetch the default non-color unicode theme for osx
+var ourTheme = themes({hasUnicode: true, hasColor: false, platform: 'darwin'})
+
+// create a new theme based on the color ascii theme for this platform
+// that brackets the progress bar with arrows
+var ourTheme = themes.newTheme(theme(hasUnicode: false, hasColor: true}), {
+ preProgressbar: '→',
+ postProgressbar: 'â†'
+})
+```
+
+The object returned by `gauge/themes` is an instance of the `ThemeSet` class.
+
+```
+var ThemeSet = require('gauge/theme-set')
+var themes = new ThemeSet()
+// or
+var themes = require('gauge/themes')
+var mythemes = themes.newThemeset() // creates a new themeset based on the default themes
+```
+
+#### themes(opts)
+#### themes.getDefault(opts)
+
+Theme objects are a function that fetches the default theme based on
+platform, unicode and color support.
+
+Options is an object with the following properties:
+
+* **hasUnicode** - If true, fetch a unicode theme, if no unicode theme is
+ available then a non-unicode theme will be used.
+* **hasColor** - If true, fetch a color theme, if no color theme is
+ available a non-color theme will be used.
+* **platform** (optional) - Defaults to `process.platform`. If no
+ platform match is available then `fallback` is used instead.
+
+If no compatible theme can be found then an error will be thrown with a
+`code` of `EMISSINGTHEME`.
+
+#### themes.addTheme(themeName, themeObj)
+#### themes.addTheme(themeName, [parentTheme], newTheme)
+
+Adds a named theme to the themeset. You can pass in either a theme object,
+as returned by `themes.newTheme` or the arguments you'd pass to
+`themes.newTheme`.
+
+#### themes.getThemeNames()
+
+Return a list of all of the names of the themes in this themeset. Suitable
+for use in `themes.getTheme(…)`.
+
+#### themes.getTheme(name)
+
+Returns the theme object from this theme set named `name`.
+
+If `name` does not exist in this themeset an error will be thrown with
+a `code` of `EMISSINGTHEME`.
+
+#### themes.setDefault([opts], themeName)
+
+`opts` is an object with the following properties.
+
+* **platform** - Defaults to `'fallback'`. If your theme is platform
+ specific, specify that here with the platform from `process.platform`, eg,
+ `win32`, `darwin`, etc.
+* **hasUnicode** - Defaults to `false`. If your theme uses unicode you
+ should set this to true.
+* **hasColor** - Defaults to `false`. If your theme uses color you should
+ set this to true.
+
+`themeName` is the name of the theme (as given to `addTheme`) to use for
+this set of `opts`.
+
+#### themes.newTheme([parentTheme,] newTheme)
+
+Create a new theme object based on `parentTheme`. If no `parentTheme` is
+provided then a minimal parentTheme that defines functions for rendering the
+activity indicator (spinner) and progress bar will be defined. (This
+fallback parent is defined in `gauge/base-theme`.)
+
+newTheme should be a bare object– we'll start by discussing the properties
+defined by the default themes:
+
+* **preProgressbar** - displayed prior to the progress bar, if the progress
+ bar is displayed.
+* **postProgressbar** - displayed after the progress bar, if the progress bar
+ is displayed.
+* **progressBarTheme** - The subtheme passed through to the progress bar
+ renderer, it's an object with `complete` and `remaining` properties
+ that are the strings you want repeated for those sections of the progress
+ bar.
+* **activityIndicatorTheme** - The theme for the activity indicator (spinner),
+ this can either be a string, in which each character is a different step, or
+ an array of strings.
+* **preSubsection** - Displayed as a separator between the `section` and
+ `subsection` when the latter is printed.
+
+More generally, themes can have any value that would be a valid value when rendering
+templates. The properties in the theme are used when their name matches a type in
+the template. Their values can be:
+
+* **strings & numbers** - They'll be included as is
+* **function (values, theme, width)** - Should return what you want in your output.
+ *values* is an object with values provided via `gauge.show`,
+ *theme* is the theme specific to this item (see below) or this theme object,
+ and *width* is the number of characters wide your result should be.
+
+There are a couple of special prefixes:
+
+* **pre** - Is shown prior to the property, if its displayed.
+* **post** - Is shown after the property, if its displayed.
+
+And one special suffix:
+
+* **Theme** - Its value is passed to a function-type item as the theme.
+
+#### themes.addToAllThemes(theme)
+
+This *mixes-in* `theme` into all themes currently defined. It also adds it
+to the default parent theme for this themeset, so future themes added to
+this themeset will get the values from `theme` by default.
+
+#### themes.newThemeset()
+
+Copy the current themeset into a new one. This allows you to easily inherit
+one themeset from another.
+
+### TEMPLATES
+
+A template is an array of objects and strings that, after being evaluated,
+will be turned into the gauge line. The default template is:
+
+```javascript
+[
+ {type: 'progressbar', length: 20},
+ {type: 'activityIndicator', kerning: 1, length: 1},
+ {type: 'section', kerning: 1, default: ''},
+ {type: 'subsection', kerning: 1, default: ''}
+]
+```
+
+The various template elements can either be **plain strings**, in which case they will
+be be included verbatum in the output, or objects with the following properties:
+
+* *type* can be any of the following plus any keys you pass into `gauge.show` plus
+ any keys you have on a custom theme.
+ * `section` – What big thing you're working on now.
+ * `subsection` – What component of that thing is currently working.
+ * `activityIndicator` – Shows a spinner using the `activityIndicatorTheme`
+ from your active theme.
+ * `progressbar` – A progress bar representing your current `completed`
+ using the `progressbarTheme` from your active theme.
+* *kerning* – Number of spaces that must be between this item and other
+ items, if this item is displayed at all.
+* *maxLength* – The maximum length for this element. If its value is longer it
+ will be truncated.
+* *minLength* – The minimum length for this element. If its value is shorter it
+ will be padded according to the *align* value.
+* *align* – (Default: left) Possible values "left", "right" and "center". Works
+ as you'd expect from word processors.
+* *length* – Provides a single value for both *minLength* and *maxLength*. If both
+ *length* and *minLength or *maxLength* are specifed then the latter take precedence.
+* *value* – A literal value to use for this template item.
+* *default* – A default value to use for this template item if a value
+ wasn't otherwise passed in.
+
+### PLUMBING
+
+This is the super simple, assume nothing, do no magic internals used by gauge to
+implement its ordinary interface.
+
+```
+var Plumbing = require('gauge/plumbing')
+var gauge = new Plumbing(theme, template, width)
+```
+
+* **theme**: The theme to use.
+* **template**: The template to use.
+* **width**: How wide your gauge should be
+
+#### `gauge.setTheme(theme)`
+
+Change the active theme.
+
+#### `gauge.setTemplate(template)`
+
+Change the active template.
+
+#### `gauge.setWidth(width)`
+
+Change the width to render at.
+
+#### `gauge.hide()`
+
+Return the string necessary to hide the progress bar
+
+#### `gauge.hideCursor()`
+
+Return a string to hide the cursor.
+
+#### `gauge.showCursor()`
+
+Return a string to show the cursor.
+
+#### `gauge.show(status)`
+
+Using `status` for values, render the provided template with the theme and return
+a string that is suitable for printing to update the gauge.

+has-unicode
+===========
+
+Try to guess if your terminal supports unicode
+
+```javascript
+var hasUnicode = require("has-unicode")
+
+if (hasUnicode()) {
+ // the terminal probably has unicode support
+}
+```
+```javascript
+var hasUnicode = require("has-unicode").tryHarder
+hasUnicode(function(unicodeSupported) {
+ if (unicodeSupported) {
+ // the terminal probably has unicode support
+ }
+})
+```
+
+## Detecting Unicode
+
+What we actually detect is UTF-8 support, as that's what Node itself supports.
+If you have a UTF-16 locale then you won't be detected as unicode capable.
+
+### Windows
+
+Since at least Windows 7, `cmd` and `powershell` have been unicode capable,
+but unfortunately even then it's not guaranteed. In many localizations it
+still uses legacy code pages and there's no facility short of running
+programs or linking C++ that will let us detect this. As such, we
+report any Windows installation as NOT unicode capable, and recommend
+that you encourage your users to override this via config.
+
+### Unix Like Operating Systems
+
+We look at the environment variables `LC_ALL`, `LC_CTYPE`, and `LANG` in
+that order. For `LC_ALL` and `LANG`, it looks for `.UTF-8` in the value.
+For `LC_CTYPE` it looks to see if the value is `UTF-8`. This is sufficient
+for most POSIX systems. While locale data can be put in `/etc/locale.conf`
+as well, AFAIK it's always copied into the environment.

+### Read/write IEEE754 floating point numbers from/to a Buffer or array-like object.
+
+## install
+
+```
+npm install ieee754
+```
+
+## methods
+
+`var ieee754 = require('ieee754')`
+
+The `ieee754` object has the following functions:
+
+```
+ieee754.read = function (buffer, offset, isLE, mLen, nBytes)
+ieee754.write = function (buffer, value, offset, isLE, mLen, nBytes)
+```
+
+The arguments mean the following:
+
+- buffer = the buffer
+- offset = offset into the buffer
+- value = value to set (only for `write`)
+- isLe = is little endian?
+- mLen = mantissa length
+- nBytes = number of bytes
+
+## what is ieee754?
+
+The IEEE Standard for Floating-Point Arithmetic (IEEE 754) is a technical standard for floating-point computation. [Read more](http://en.wikipedia.org/wiki/IEEE_floating_point).

+Browser-friendly inheritance fully compatible with standard node.js
+[inherits](http://nodejs.org/api/util.html#util_util_inherits_constructor_superconstructor).
+
+This package exports standard `inherits` from node.js `util` module in
+node environment, but also provides alternative browser-friendly
+implementation through [browser
+field](https://gist.github.com/shtylman/4339901). Alternative
+implementation is a literal copy of standard one located in standalone
+module to avoid requiring of `util`. It also has a shim for old
+browsers with no `Object.create` support.
+
+While keeping you sure you are using standard `inherits`
+implementation in node.js environment, it allows bundlers such as
+[browserify](https://github.com/substack/node-browserify) to not
+include full `util` package to your client code if all you need is
+just `inherits` function. It worth, because browser shim for `util`
+package is large and `inherits` is often the single function you need
+from it.
+
+It's recommended to use this package instead of
+`require('util').inherits` for any code that has chances to be used
+not only in node.js but in browser too.
+
+## usage
+
+```js
+var inherits = require('inherits');
+// then use exactly as the standard one
+```
+
+## note on version ~1.0
+
+Version ~1.0 had completely different motivation and is not compatible
+neither with 2.0 nor with standard node.js `inherits`.
+
+If you are using version ~1.0 and planning to switch to ~2.0, be
+careful:
+
+* new version uses `super_` instead of `super` for referencing
+ superclass
+* new version overwrites current prototype while old one preserves any
+ existing fields on it

+An ini format parser and serializer for node.
+
+Sections are treated as nested objects. Items before the first
+heading are saved on the object directly.
+
+## Usage
+
+Consider an ini-file `config.ini` that looks like this:
+
+ ; this comment is being ignored
+ scope = global
+
+ [database]
+ user = dbuser
+ password = dbpassword
+ database = use_this_database
+
+ [paths.default]
+ datadir = /var/lib/data
+ array[] = first value
+ array[] = second value
+ array[] = third value
+
+You can read, manipulate and write the ini-file like so:
+
+ var fs = require('fs')
+ , ini = require('ini')
+
+ var config = ini.parse(fs.readFileSync('./config.ini', 'utf-8'))
+
+ config.scope = 'local'
+ config.database.database = 'use_another_database'
+ config.paths.default.tmpdir = '/tmp'
+ delete config.paths.default.datadir
+ config.paths.default.array.push('fourth value')
+
+ fs.writeFileSync('./config_modified.ini', ini.stringify(config, { section: 'section' }))
+
+This will result in a file called `config_modified.ini` being written
+to the filesystem with the following content:
+
+ [section]
+ scope=local
+ [section.database]
+ user=dbuser
+ password=dbpassword
+ database=use_another_database
+ [section.paths.default]
+ tmpdir=/tmp
+ array[]=first value
+ array[]=second value
+ array[]=third value
+ array[]=fourth value
+
+
+## API
+
+### decode(inistring)
+
+Decode the ini-style formatted `inistring` into a nested object.
+
+### parse(inistring)
+
+Alias for `decode(inistring)`
+
+### encode(object, [options])
+
+Encode the object `object` into an ini-style formatted string. If the
+optional parameter `section` is given, then all top-level properties
+of the object are put into this section and the `section`-string is
+prepended to all sub-sections, see the usage example above.
+
+The `options` object may contain the following:
+
+* `section` A string which will be the first `section` in the encoded
+ ini data. Defaults to none.
+* `whitespace` Boolean to specify whether to put whitespace around the
+ `=` character. By default, whitespace is omitted, to be friendly to
+ some persnickety old parsers that don't tolerate it well. But some
+ find that it's more human-readable and pretty with the whitespace.
+
+For backwards compatibility reasons, if a `string` options is passed
+in, then it is assumed to be the `section` value.
+
+### stringify(object, [options])
+
+Alias for `encode(object, [options])`
+
+### safe(val)
+
+Escapes the string `val` such that it is safe to be used as a key or
+value in an ini-file. Basically escapes quotes. For example
+
+ ini.safe('"unsafe string"')
+
+would result in
+
+ "\"unsafe string\""
+
+### unsafe(val)
+
+Unescapes the string `val`

+# minimist
+
+parse argument options
+
+This module is the guts of optimist's argument parser without all the
+fanciful decoration.
+
+# example
+
+``` js
+var argv = require('minimist')(process.argv.slice(2));
+console.log(argv);
+```
+
+```
+$ node example/parse.js -a beep -b boop
+{ _: [], a: 'beep', b: 'boop' }
+```
+
+```
+$ node example/parse.js -x 3 -y 4 -n5 -abc --beep=boop foo bar baz
+{ _: [ 'foo', 'bar', 'baz' ],
+ x: 3,
+ y: 4,
+ n: 5,
+ a: true,
+ b: true,
+ c: true,
+ beep: 'boop' }
+```
+
+# security
+
+Previous versions had a prototype pollution bug that could cause privilege
+escalation in some circumstances when handling untrusted user input.
+
+Please use version 1.2.3 or later: https://snyk.io/vuln/SNYK-JS-MINIMIST-559764
+
+# methods
+
+``` js
+var parseArgs = require('minimist')
+```
+
+## var argv = parseArgs(args, opts={})
+
+Return an argument object `argv` populated with the array arguments from `args`.
+
+`argv._` contains all the arguments that didn't have an option associated with
+them.
+
+Numeric-looking arguments will be returned as numbers unless `opts.string` or
+`opts.boolean` is set for that argument name.
+
+Any arguments after `'--'` will not be parsed and will end up in `argv._`.
+
+options can be:
+
+* `opts.string` - a string or array of strings argument names to always treat as
+strings
+* `opts.boolean` - a boolean, string or array of strings to always treat as
+booleans. if `true` will treat all double hyphenated arguments without equal signs
+as boolean (e.g. affects `--foo`, not `-f` or `--foo=bar`)
+* `opts.alias` - an object mapping string names to strings or arrays of string
+argument names to use as aliases
+* `opts.default` - an object mapping string argument names to default values
+* `opts.stopEarly` - when true, populate `argv._` with everything after the
+first non-option
+* `opts['--']` - when true, populate `argv._` with everything before the `--`
+and `argv['--']` with everything after the `--`. Here's an example:
+
+ ```
+ > require('./')('one two three -- four five --six'.split(' '), { '--': true })
+ { _: [ 'one', 'two', 'three' ],
+ '--': [ 'four', 'five', '--six' ] }
+ ```
+
+ Note that with `opts['--']` set, parsing for arguments still stops after the
+ `--`.
+
+* `opts.unknown` - a function which is invoked with a command line parameter not
+defined in the `opts` configuration object. If the function returns `false`, the
+unknown option is not added to `argv`.
+
+# install
+
+With [npm](https://npmjs.org) do:
+
+```
+npm install minimist
+```

+# ms
+
+[](https://travis-ci.org/zeit/ms)
+[](https://spectrum.chat/zeit)
+
+Use this package to easily convert various time formats to milliseconds.
+
+## Examples
+
+```js
+ms('2 days') // 172800000
+ms('1d') // 86400000
+ms('10h') // 36000000
+ms('2.5 hrs') // 9000000
+ms('2h') // 7200000
+ms('1m') // 60000
+ms('5s') // 5000
+ms('1y') // 31557600000
+ms('100') // 100
+ms('-3 days') // -259200000
+ms('-1h') // -3600000
+ms('-200') // -200
+```
+
+### Convert from Milliseconds
+
+```js
+ms(60000) // "1m"
+ms(2 * 60000) // "2m"
+ms(-3 * 60000) // "-3m"
+ms(ms('10 hours')) // "10h"
+```
+
+### Time Format Written-Out
+
+```js
+ms(60000, { long: true }) // "1 minute"
+ms(2 * 60000, { long: true }) // "2 minutes"
+ms(-3 * 60000, { long: true }) // "-3 minutes"
+ms(ms('10 hours'), { long: true }) // "10 hours"
+```
+
+## Features
+
+- Works both in [Node.js](https://nodejs.org) and in the browser
+- If a number is supplied to `ms`, a string with a unit is returned
+- If a string that contains the number is supplied, it returns it as a number (e.g.: it returns `100` for `'100'`)
+- If you pass a string with a number and a valid unit, the number of equivalent milliseconds is returned
+
+## Related Packages
+
+- [ms.macro](https://github.com/knpwrs/ms.macro) - Run `ms` as a macro at build-time.
+
+## Caught a Bug?
+
+1. [Fork](https://help.github.com/articles/fork-a-repo/) this repository to your own GitHub account and then [clone](https://help.github.com/articles/cloning-a-repository/) it to your local device
+2. Link the package to the global module directory: `npm link`
+3. Within the module you want to test your local development instance of ms, just link it to the dependencies: `npm link ms`. Instead of the default one from npm, Node.js will now use your clone of ms!
+
+As always, you can run the tests using: `npm test`

+Native Abstractions for Node.js
+===============================
+
+**A header file filled with macro and utility goodness for making add-on development for Node.js easier across versions 0.8, 0.10, 0.12, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13 and 14.**

+
+Thanks to the crazy changes in V8 (and some in Node core), keeping native addons compiling happily across versions, particularly 0.10 to 0.12 to 4.0, is a minor nightmare. The goal of this project is to store all logic necessary to develop native Node.js addons without having to inspect `NODE_MODULE_VERSION` and get yourself into a macro-tangle.
+
+This project also contains some helper utilities that make addon development a bit more pleasant.

+## News & Updates
+
+<a name="usage"></a>
+
+## Usage
+
+Simply add **NAN** as a dependency in the *package.json* of your Node addon:
+
+``` bash
+$ npm install --save nan
+```
+
+Pull in the path to **NAN** in your *binding.gyp* so that you can use `#include <nan.h>` in your *.cpp* files:
+
+``` python
+"include_dirs" : [
+ "<!(node -e \"require('nan')\")"
+]
+```
+
+This works like a `-I<path-to-NAN>` when compiling your addon.
+
+<a name="example"></a>
+
+## Example
+
+Just getting started with Nan? Take a look at the **[Node Add-on Examples](https://github.com/nodejs/node-addon-examples)**.
+
+Refer to a [quick-start **Nan** Boilerplate](https://github.com/fcanas/node-native-boilerplate) for a ready-to-go project that utilizes basic Nan functionality.
+
+For a simpler example, see the **[async pi estimation example](https://github.com/nodejs/nan/tree/master/examples/async_pi_estimate)** in the examples directory for full code and an explanation of what this Monte Carlo Pi estimation example does. Below are just some parts of the full example that illustrate the use of **NAN**.
+
+Yet another example is **[nan-example-eol](https://github.com/CodeCharmLtd/nan-example-eol)**. It shows newline detection implemented as a native addon.
+
+Also take a look at our comprehensive **[C++ test suite](https://github.com/nodejs/nan/tree/master/test/cpp)** which has a plethora of code snippets for your pasting pleasure.

+
+### JavaScript-accessible methods
+
+A _template_ is a blueprint for JavaScript functions and objects in a context. You can use a template to wrap C++ functions and data structures within JavaScript objects so that they can be manipulated from JavaScript. See the V8 Embedders Guide section on [Templates](https://github.com/v8/v8/wiki/Embedder%27s-Guide#templates) for further information.
+
+In order to expose functionality to JavaScript via a template, you must provide it to V8 in a form that it understands. Across the versions of V8 supported by NAN, JavaScript-accessible method signatures vary widely, NAN fully abstracts method declaration and provides you with an interface that is similar to the most recent V8 API but is backward-compatible with older versions that still use the now-deceased `v8::Argument` type.

+
+### Scopes
+
+A _local handle_ is a pointer to an object. All V8 objects are accessed using handles, they are necessary because of the way the V8 garbage collector works.
+
+A handle scope can be thought of as a container for any number of handles. When you've finished with your handles, instead of deleting each one individually you can simply delete their scope.
+
+The creation of `HandleScope` objects is different across the supported versions of V8. Therefore, NAN provides its own implementations that can be used safely across these.
+
+ - <a href="doc/scopes.md#api_nan_handle_scope"><b><code>Nan::HandleScope</code></b></a>
+ - <a href="doc/scopes.md#api_nan_escapable_handle_scope"><b><code>Nan::EscapableHandleScope</code></b></a>
+
+Also see the V8 Embedders Guide section on [Handles and Garbage Collection](https://github.com/v8/v8/wiki/Embedder%27s%20Guide#handles-and-garbage-collection).

+An object reference that is independent of any `HandleScope` is a _persistent_ reference. Where a `Local` handle only lives as long as the `HandleScope` in which it was allocated, a `Persistent` handle remains valid until it is explicitly disposed.
+
+Due to the evolution of the V8 API, it is necessary for NAN to provide a wrapper implementation of the `Persistent` classes to supply compatibility across the V8 versions supported.

+
+### New
+
+NAN provides a `Nan::New()` helper for the creation of new JavaScript objects in a way that's compatible across the supported versions of V8.

+
+
+### Converters
+
+NAN contains functions that convert `v8::Value`s to other `v8::Value` types and native types. Since type conversion is not guaranteed to succeed, they return `Nan::Maybe` types. These converters can be used in place of `value->ToX()` and `value->XValue()` (where `X` is one of the types, e.g. `Boolean`) in a way that provides a consistent interface across V8 versions. Newer versions of V8 use the new `v8::Maybe` and `v8::MaybeLocal` types for these conversions, older versions don't have this functionality so it is provided by NAN.

+
+### Maybe Types
+
+The `Nan::MaybeLocal` and `Nan::Maybe` types are monads that encapsulate `v8::Local` handles that _may be empty_.

+
+### Script
+
+NAN provides a `v8::Script` helpers as the API has changed over the supported versions of V8.
+
+ - <a href="doc/script.md#api_nan_compile_script"><b><code>Nan::CompileScript()</code></b></a>
+ - <a href="doc/script.md#api_nan_run_script"><b><code>Nan::RunScript()</code></b></a>
+
+
+### JSON
+
+The _JSON_ object provides the C++ versions of the methods offered by the `JSON` object in javascript. V8 exposes these methods via the `v8::JSON` object.
+
+ - <a href="doc/json.md#api_nan_json_parse"><b><code>Nan::JSON.Parse</code></b></a>
+ - <a href="doc/json.md#api_nan_json_stringify"><b><code>Nan::JSON.Stringify</code></b></a>
+
+Refer to the V8 JSON object in the [V8 documentation](https://v8docs.nodesource.com/node-8.16/da/d6f/classv8_1_1_j_s_o_n.html) for more information about these methods and their arguments.
+
+### Errors
+
+NAN includes helpers for creating, throwing and catching Errors as much of this functionality varies across the supported versions of V8 and must be abstracted.
+
+Note that an Error object is simply a specialized form of `v8::Value`.
+
+Also consult the V8 Embedders Guide section on [Exceptions](https://developers.google.com/v8/embed#exceptions) for more information.

+
+
+### Buffers
+
+NAN's `node::Buffer` helpers exist as the API has changed across supported Node versions. Use these methods to ensure compatibility.
+
+ - <a href="doc/buffers.md#api_nan_new_buffer"><b><code>Nan::NewBuffer()</code></b></a>

+ - <a href="doc/buffers.md#api_nan_free_callback"><b><code>Nan::FreeCallback()</code></b></a>
+
+### Nan::Callback
+
+`Nan::Callback` makes it easier to use `v8::Function` handles as callbacks. A class that wraps a `v8::Function` handle, protecting it from garbage collection and making it particularly useful for storage and use across asynchronous execution.
+
+ - <a href="doc/callback.md#api_nan_callback"><b><code>Nan::Callback</code></b></a>
+
+### Asynchronous work helpers
+
+`Nan::AsyncWorker`, `Nan::AsyncProgressWorker` and `Nan::AsyncProgressQueueWorker` are helper classes that make working with asynchronous code easier.

+ - <a href="doc/asyncworker.md#api_nan_async_queue_worker"><b><code>Nan::AsyncQueueWorker</code></b></a>
+
+### Strings & Bytes
+
+Miscellaneous string & byte encoding and decoding functionality provided for compatibility across supported versions of V8 and Node. Implemented by NAN to ensure that all encoding types are supported, even for older versions of Node where they are missing.

+
+
+### Object Wrappers

+ - <a href="doc/object_wrappers.md#api_nan_object_wrap"><b><code>Nan::ObjectWrap</code></b></a>
+
+
+### V8 internals
+
+The hooks to access V8 internals—including GC and statistics—are different across the supported versions of V8, therefore NAN provides its own hooks that call the appropriate V8 methods.

+## Known issues
+
+### Compiling against Node.js 0.12 on OSX
+
+With new enough compilers available on OSX, the versions of V8 headers corresponding to Node.js 0.12
+do not compile anymore. The error looks something like:
+
+```
+⯠CXX(target) Release/obj.target/accessors/cpp/accessors.o
+In file included from ../cpp/accessors.cpp:9:
+In file included from ../../nan.h:51:
+In file included from /Users/ofrobots/.node-gyp/0.12.18/include/node/node.h:61:
+/Users/ofrobots/.node-gyp/0.12.18/include/node/v8.h:5800:54: error: 'CreateHandle' is a protected member of 'v8::HandleScope'
+ return Handle<T>(reinterpret_cast<T*>(HandleScope::CreateHandle(
+ ~~~~~~~~~~~~~^~~~~~~~~~~~
+```
+
+This can be worked around by patching your local versions of v8.h corresponding to Node 0.12 to make
+`v8::Handle` a friend of `v8::HandleScope`. Since neither Node.js not V8 support this release line anymore
+this patch cannot be released by either project in an official release.
+
+For this reason, we do not test against Node.js 0.12 on OSX in this project's CI. If you need to support
+that configuration, you will need to either get an older compiler, or apply a source patch to the version
+of V8 headers as a workaround.

+
+## Governance & Contributing
+
+NAN is governed by the [Node.js Addon API Working Group](https://github.com/nodejs/CTC/blob/master/WORKING_GROUPS.md#addon-api)
+
+### Addon API Working Group (WG)
+
+The NAN project is jointly governed by a Working Group which is responsible for high-level guidance of the project.
+
+Members of the WG are also known as Collaborators, there is no distinction between the two, unlike other Node.js projects.
+
+The WG has final authority over this project including:
+
+* Technical direction
+* Project governance and process (including this policy)
+* Contribution policy
+* GitHub repository hosting
+* Maintaining the list of additional Collaborators
+
+For the current list of WG members, see the project [README.md](./README.md#collaborators).
+
+Individuals making significant and valuable contributions are made members of the WG and given commit-access to the project. These individuals are identified by the WG and their addition to the WG is discussed via GitHub and requires unanimous consensus amongst those WG members participating in the discussion with a quorum of 50% of WG members required for acceptance of the vote.
+
+_Note:_ If you make a significant contribution and are not considered for commit-access log an issue or contact a WG member directly.
+
+For the current list of WG members / Collaborators, see the project [README.md](./README.md#collaborators).
+
+### Consensus Seeking Process
+
+The WG follows a [Consensus Seeking](https://en.wikipedia.org/wiki/Consensus-seeking_decision-making) decision making model.
+
+Modifications of the contents of the NAN repository are made on a collaborative basis. Anybody with a GitHub account may propose a modification via pull request and it will be considered by the WG. All pull requests must be reviewed and accepted by a WG member with sufficient expertise who is able to take full responsibility for the change. In the case of pull requests proposed by an existing WG member, an additional WG member is required for sign-off. Consensus should be sought if additional WG members participate and there is disagreement around a particular modification.
+
+If a change proposal cannot reach a consensus, a WG member can call for a vote amongst the members of the WG. Simple majority wins.

+## Asynchronous work helpers
+
+`Nan::AsyncWorker`, `Nan::AsyncProgressWorker` and `Nan::AsyncProgressQueueWorker` are helper classes that make working with asynchronous code easier.

+### Nan::AsyncWorker
+
+`Nan::AsyncWorker` is an _abstract_ class that you can subclass to have much of the annoying asynchronous queuing and handling taken care of for you. It can even store arbitrary V8 objects for you and have them persist while the asynchronous work is in progress.
+
+This class internally handles the details of creating an [`AsyncResource`][AsyncResource], and running the callback in the
+correct async context. To be able to identify the async resources created by this class in async-hooks, provide a
+`resource_name` to the constructor. It is recommended that the module name be used as a prefix to the `resource_name` to avoid
+collisions in the names. For more details see [`AsyncResource`][AsyncResource] documentation. The `resource_name` needs to stay valid for the lifetime of the worker instance.
+
+Definition:
+
+```c++
+class AsyncWorker {
+ public:
+ explicit AsyncWorker(Callback *callback_, const char* resource_name = "nan:AsyncWorker");
+
+ virtual ~AsyncWorker();
+
+ virtual void WorkComplete();
+
+ void SaveToPersistent(const char *key, const v8::Local<v8::Value> &value);
+
+ void SaveToPersistent(const v8::Local<v8::String> &key,
+ const v8::Local<v8::Value> &value);
+
+ void SaveToPersistent(uint32_t index,
+ const v8::Local<v8::Value> &value);
+
+ v8::Local<v8::Value> GetFromPersistent(const char *key) const;
+
+ v8::Local<v8::Value> GetFromPersistent(const v8::Local<v8::String> &key) const;
+
+ v8::Local<v8::Value> GetFromPersistent(uint32_t index) const;
+
+ virtual void Execute() = 0;
+

+
+ virtual void Destroy();
+

+ Persistent<v8::Object> persistentHandle;
+
+ Callback *callback;
+

+
+ virtual void HandleErrorCallback();
+
+ void SetErrorMessage(const char *msg);
+
+ const char* ErrorMessage();
+};
+```

+<a name="api_nan_async_progress_worker"></a>
+### Nan::AsyncProgressWorkerBase & Nan::AsyncProgressWorker
+
+`Nan::AsyncProgressWorkerBase` is an _abstract_ class template that extends `Nan::AsyncWorker` and adds additional progress reporting callbacks that can be used during the asynchronous work execution to provide progress data back to JavaScript.
+
+Previously the definition of `Nan::AsyncProgressWorker` only allowed sending `const char` data. Now extending `Nan::AsyncProgressWorker` will yield an instance of the implicit `Nan::AsyncProgressWorkerBase` template with type `<char>` for compatibility.
+
+`Nan::AsyncProgressWorkerBase` & `Nan::AsyncProgressWorker` is intended for best-effort delivery of nonessential progress messages, e.g. a progress bar. The last event sent before the main thread is woken will be delivered.

+### Nan::AsyncProgressQueueWorker
+
+`Nan::AsyncProgressQueueWorker` is an _abstract_ class template that extends `Nan::AsyncWorker` and adds additional progress reporting callbacks that can be used during the asynchronous work execution to provide progress data back to JavaScript.
+
+`Nan::AsyncProgressQueueWorker` behaves exactly the same as `Nan::AsyncProgressWorker`, except all events are queued and delivered to the main thread.

+
+```c++
+template<class T>
+class AsyncProgressQueueWorker<T> : public AsyncWorker {

+
+ virtual void Destroy();
+};
+```
+
+<a name="api_nan_async_queue_worker"></a>
+### Nan::AsyncQueueWorker
+
+`Nan::AsyncQueueWorker` will run a `Nan::AsyncWorker` asynchronously via libuv. Both the `execute` and `after_work` steps are taken care of for you. Most of the logic for this is embedded in `Nan::AsyncWorker`.

+## Buffers
+
+NAN's `node::Buffer` helpers exist as the API has changed across supported Node versions. Use these methods to ensure compatibility.

+
+<a name="api_nan_new_buffer"></a>
+### Nan::NewBuffer()
+
+Allocate a new `node::Buffer` object with the specified size and optional data. Calls `node::Buffer::New()`.
+
+Note that when creating a `Buffer` using `Nan::NewBuffer()` and an existing `char*`, it is assumed that the ownership of the pointer is being transferred to the new `Buffer` for management.
+When a `node::Buffer` instance is garbage collected and a `FreeCallback` has not been specified, `data` will be disposed of via a call to `free()`.
+You _must not_ free the memory space manually once you have created a `Buffer` in this way.

+
+
+<a name="api_nan_copy_buffer"></a>
+### Nan::CopyBuffer()
+
+Similar to [`Nan::NewBuffer()`](#api_nan_new_buffer) except that an implicit memcpy will occur within Node. Calls `node::Buffer::Copy()`.
+
+Management of the `char*` is left to the user, you should manually free the memory space if necessary as the new `Buffer` will have its own copy.

+
+A free callback that can be provided to [`Nan::NewBuffer()`](#api_nan_new_buffer).
+The supplied callback will be invoked when the `Buffer` undergoes garbage collection.

+## Converters
+
+NAN contains functions that convert `v8::Value`s to other `v8::Value` types and native types. Since type conversion is not guaranteed to succeed, they return `Nan::Maybe` types. These converters can be used in place of `value->ToX()` and `value->XValue()` (where `X` is one of the types, e.g. `Boolean`) in a way that provides a consistent interface across V8 versions. Newer versions of V8 use the new `v8::Maybe` and `v8::MaybeLocal` types for these conversions, older versions don't have this functionality so it is provided by NAN.

+### Nan::To()
+
+Converts a `v8::Local<v8::Value>` to a different subtype of `v8::Value` or to a native data type. Returns a `Nan::MaybeLocal<>` or a `Nan::Maybe<>` accordingly.

+### Nan::MaybeLocal
+
+A `Nan::MaybeLocal<T>` is a wrapper around [`v8::Local<T>`](https://v8docs.nodesource.com/node-8.16/de/deb/classv8_1_1_local.html) that enforces a check that determines whether the `v8::Local<T>` is empty before it can be used.
+
+If an API method returns a `Nan::MaybeLocal`, the API method can potentially fail either because an exception is thrown, or because an exception is pending, e.g. because a previous API call threw an exception that hasn't been caught yet, or because a `v8::TerminateExecution` exception was thrown. In that case, an empty `Nan::MaybeLocal` is returned.
+
+Definition:
+
+```c++
+template<typename T> class Nan::MaybeLocal {
+ public:
+ MaybeLocal();
+
+ template<typename S> MaybeLocal(v8::Local<S> that);
+
+ bool IsEmpty() const;
+
+ template<typename S> bool ToLocal(v8::Local<S> *out);
+
+ // Will crash if the MaybeLocal<> is empty.
+ v8::Local<T> ToLocalChecked();
+
+ template<typename S> v8::Local<S> FromMaybe(v8::Local<S> default_value) const;
+};
+```
+
+See the documentation for [`v8::MaybeLocal`](https://v8docs.nodesource.com/node-8.16/d8/d7d/classv8_1_1_maybe_local.html) for further details.

+### Nan::Maybe
+
+A simple `Nan::Maybe` type, representing an object which may or may not have a value, see https://hackage.haskell.org/package/base/docs/Data-Maybe.html.
+
+If an API method returns a `Nan::Maybe<>`, the API method can potentially fail either because an exception is thrown, or because an exception is pending, e.g. because a previous API call threw an exception that hasn't been caught yet, or because a `v8::TerminateExecution` exception was thrown. In that case, a "Nothing" value is returned.
+
+Definition:
+
+```c++
+template<typename T> class Nan::Maybe {
+ public:
+ bool IsNothing() const;
+ bool IsJust() const;
+
+ // Will crash if the Maybe<> is nothing.

+## JavaScript-accessible methods
+
+A _template_ is a blueprint for JavaScript functions and objects in a context. You can use a template to wrap C++ functions and data structures within JavaScript objects so that they can be manipulated from JavaScript. See the V8 Embedders Guide section on [Templates](https://github.com/v8/v8/wiki/Embedder%27s-Guide#templates) for further information.
+
+In order to expose functionality to JavaScript via a template, you must provide it to V8 in a form that it understands. Across the versions of V8 supported by NAN, JavaScript-accessible method signatures vary widely, NAN fully abstracts method declaration and provides you with an interface that is similar to the most recent V8 API but is backward-compatible with older versions that still use the now-deceased `v8::Argument` type.

+### Nan::FunctionCallbackInfo
+
+`Nan::FunctionCallbackInfo` should be used in place of [`v8::FunctionCallbackInfo`](https://v8docs.nodesource.com/node-8.16/dd/d0d/classv8_1_1_function_callback_info.html), even with older versions of Node where `v8::FunctionCallbackInfo` does not exist.
+
+Definition:
+
+```c++
+template<typename T> class FunctionCallbackInfo {
+ public:
+ ReturnValue<T> GetReturnValue() const;
+ v8::Local<v8::Function> Callee(); // NOTE: Not available in NodeJS >= 10.0.0
+ v8::Local<v8::Value> Data();
+ v8::Local<v8::Object> Holder();
+ bool IsConstructCall();
+ int Length() const;
+ v8::Local<v8::Value> operator[](int i) const;
+ v8::Local<v8::Object> This() const;
+ v8::Isolate *GetIsolate() const;
+};
+```
+
+See the [`v8::FunctionCallbackInfo`](https://v8docs.nodesource.com/node-8.16/dd/d0d/classv8_1_1_function_callback_info.html) documentation for usage details on these. See [`Nan::ReturnValue`](#api_nan_return_value) for further information on how to set a return value from methods.
+
+**Note:** `FunctionCallbackInfo::Callee` is removed in Node.js after `10.0.0` because it is was deprecated in V8. Consider using `info.Data()` to pass any information you need.
+
+<a name="api_nan_property_callback_info"></a>
+### Nan::PropertyCallbackInfo
+
+`Nan::PropertyCallbackInfo` should be used in place of [`v8::PropertyCallbackInfo`](https://v8docs.nodesource.com/node-8.16/d7/dc5/classv8_1_1_property_callback_info.html), even with older versions of Node where `v8::PropertyCallbackInfo` does not exist.
+
+Definition:
+
+```c++
+template<typename T> class PropertyCallbackInfo : public PropertyCallbackInfoBase<T> {
+ public:
+ ReturnValue<T> GetReturnValue() const;
+ v8::Isolate* GetIsolate() const;
+ v8::Local<v8::Value> Data() const;
+ v8::Local<v8::Object> This() const;
+ v8::Local<v8::Object> Holder() const;
+};
+```
+
+See the [`v8::PropertyCallbackInfo`](https://v8docs.nodesource.com/node-8.16/d7/dc5/classv8_1_1_property_callback_info.html) documentation for usage details on these. See [`Nan::ReturnValue`](#api_nan_return_value) for further information on how to set a return value from property accessor methods.
+
+<a name="api_nan_return_value"></a>
+### Nan::ReturnValue
+
+`Nan::ReturnValue` is used in place of [`v8::ReturnValue`](https://v8docs.nodesource.com/node-8.16/da/da7/classv8_1_1_return_value.html) on both [`Nan::FunctionCallbackInfo`](#api_nan_function_callback_info) and [`Nan::PropertyCallbackInfo`](#api_nan_property_callback_info) as the return type of `GetReturnValue()`.
+
+Example usage:
+
+```c++
+void EmptyArray(const Nan::FunctionCallbackInfo<v8::Value>& info) {
+ info.GetReturnValue().Set(Nan::New<v8::Array>());
+}
+```
+
+Definition:
+
+```c++
+template<typename T> class ReturnValue {
+ public:
+ // Handle setters
+ template <typename S> void Set(const v8::Local<S> &handle);
+ template <typename S> void Set(const Nan::Global<S> &handle);
+
+ // Fast primitive setters
+ void Set(bool value);
+ void Set(double i);
+ void Set(int32_t i);
+ void Set(uint32_t i);
+
+ // Fast JS primitive setters
+ void SetNull();
+ void SetUndefined();
+ void SetEmptyString();
+
+ // Convenience getter for isolate
+ v8::Isolate *GetIsolate() const;
+};
+```
+
+See the documentation on [`v8::ReturnValue`](https://v8docs.nodesource.com/node-8.16/da/da7/classv8_1_1_return_value.html) for further information on this.
+
+<a name="api_nan_method"></a>
+### Method declaration
+
+JavaScript-accessible methods should be declared with the following signature to form a `Nan::FunctionCallback`:
+
+```c++
+typedef void(*FunctionCallback)(const FunctionCallbackInfo<v8::Value>&);
+```
+
+Example:
+
+```c++
+void MethodName(const Nan::FunctionCallbackInfo<v8::Value>& info) {
+ ...
+}
+```
+
+You do not need to declare a new `HandleScope` within a method as one is implicitly created for you.
+
+**Example usage**
+
+```c++
+// .h:
+class Foo : public Nan::ObjectWrap {
+ ...
+
+ static void Bar(const Nan::FunctionCallbackInfo<v8::Value>& info);
+ static void Baz(const Nan::FunctionCallbackInfo<v8::Value>& info);
+}
+
+
+// .cc:
+void Foo::Bar(const Nan::FunctionCallbackInfo<v8::Value>& info) {
+ ...
+}
+
+void Foo::Baz(const Nan::FunctionCallbackInfo<v8::Value>& info) {
+ ...
+}
+```
+
+A helper macro `NAN_METHOD(methodname)` exists, compatible with NAN v1 method declarations.
+
+**Example usage with `NAN_METHOD(methodname)`**
+
+```c++
+// .h:
+class Foo : public Nan::ObjectWrap {
+ ...
+
+ static NAN_METHOD(Bar);
+ static NAN_METHOD(Baz);
+}
+
+
+// .cc:
+NAN_METHOD(Foo::Bar) {
+ ...
+}
+
+NAN_METHOD(Foo::Baz) {
+ ...
+}
+```
+
+Use [`Nan::SetPrototypeMethod`](#api_nan_set_prototype_method) to attach a method to a JavaScript function prototype or [`Nan::SetMethod`](#api_nan_set_method) to attach a method directly on a JavaScript object.

+## New
+
+NAN provides a `Nan::New()` helper for the creation of new JavaScript objects in a way that's compatible across the supported versions of V8.

+ - <a href="#api_nan_empty_string"><b><code>Nan::EmptyString()</code></b></a>
+
+
+<a name="api_nan_new"></a>
+### Nan::New()
+
+`Nan::New()` should be used to instantiate new JavaScript objects.
+
+Refer to the specific V8 type in the [V8 documentation](https://v8docs.nodesource.com/node-8.16/d1/d83/classv8_1_1_data.html) for information on the types of arguments required for instantiation.
+
+Signatures:
+
+Return types are mostly omitted from the signatures for simplicity. In most cases the type will be contained within a `v8::Local<T>`. The following types will be contained within a `Nan::MaybeLocal<T>`: `v8::String`, `v8::Date`, `v8::RegExp`, `v8::Script`, `v8::UnboundScript`.
+
+Empty objects:
+
+```c++
+Nan::New<T>();
+```
+
+Generic single and multiple-argument:
+
+```c++
+Nan::New<T>(A0 arg0);
+Nan::New<T>(A0 arg0, A1 arg1);
+Nan::New<T>(A0 arg0, A1 arg1, A2 arg2);
+Nan::New<T>(A0 arg0, A1 arg1, A2 arg2, A3 arg3);
+```
+
+For creating `v8::FunctionTemplate` and `v8::Function` objects:
+
+_The definition of `Nan::FunctionCallback` can be found in the [Method declaration](./methods.md#api_nan_method) documentation._
+
+```c++
+Nan::New<T>(Nan::FunctionCallback callback,
+ v8::Local<v8::Value> data = v8::Local<v8::Value>());
+Nan::New<T>(Nan::FunctionCallback callback,
+ v8::Local<v8::Value> data = v8::Local<v8::Value>(),
+ A2 a2 = A2());
+```
+
+Native number types:
+
+```c++
+v8::Local<v8::Boolean> Nan::New<T>(bool value);
+v8::Local<v8::Int32> Nan::New<T>(int32_t value);
+v8::Local<v8::Uint32> Nan::New<T>(uint32_t value);
+v8::Local<v8::Number> Nan::New<T>(double value);
+```
+
+String types:
+
+```c++
+Nan::MaybeLocal<v8::String> Nan::New<T>(std::string const& value);
+Nan::MaybeLocal<v8::String> Nan::New<T>(const char * value, int length);
+Nan::MaybeLocal<v8::String> Nan::New<T>(const char * value);
+Nan::MaybeLocal<v8::String> Nan::New<T>(const uint16_t * value);
+Nan::MaybeLocal<v8::String> Nan::New<T>(const uint16_t * value, int length);
+```
+
+Specialized types:
+
+```c++
+v8::Local<v8::String> Nan::New<T>(v8::String::ExternalStringResource * value);
+v8::Local<v8::String> Nan::New<T>(Nan::ExternalOneByteStringResource * value);
+v8::Local<v8::RegExp> Nan::New<T>(v8::Local<v8::String> pattern, v8::RegExp::Flags flags);
+```
+
+Note that `Nan::ExternalOneByteStringResource` maps to [`v8::String::ExternalOneByteStringResource`](https://v8docs.nodesource.com/node-8.16/d9/db3/classv8_1_1_string_1_1_external_one_byte_string_resource.html), and `v8::String::ExternalAsciiStringResource` in older versions of V8.

+ - <a href="#api_nan_module_init"><b><code>NAN_MODULE_INIT()</code></b></a>
+ - <a href="#api_nan_export"><b><code>Nan::Export()</code></b></a>
+
+<a name="api_nan_asyncresource"></a>
+### Nan::AsyncResource
+
+This class is analogous to the `AsyncResource` JavaScript class exposed by Node's [async_hooks][] API.
+
+When calling back into JavaScript asynchronously, special care must be taken to ensure that the runtime can properly track
+async hops. `Nan::AsyncResource` is a class that provides an RAII wrapper around `node::EmitAsyncInit`, `node::EmitAsyncDestroy`,
+and `node::MakeCallback`. Using this mechanism to call back into JavaScript, as opposed to `Nan::MakeCallback` or
+`v8::Function::Call` ensures that the callback is executed in the correct async context. This ensures that async mechanisms
+such as domains and [async_hooks][] function correctly.
+
+Definition:
+
+```c++
+class AsyncResource {
+ public:
+ AsyncResource(v8::Local<v8::String> name,
+ v8::Local<v8::Object> resource = New<v8::Object>());
+ AsyncResource(const char* name,
+ v8::Local<v8::Object> resource = New<v8::Object>());
+ ~AsyncResource();
+
+ v8::MaybeLocal<v8::Value> runInAsyncScope(v8::Local<v8::Object> target,
+ v8::Local<v8::Function> func,
+ int argc,
+ v8::Local<v8::Value>* argv);
+ v8::MaybeLocal<v8::Value> runInAsyncScope(v8::Local<v8::Object> target,
+ v8::Local<v8::String> symbol,
+ int argc,
+ v8::Local<v8::Value>* argv);
+ v8::MaybeLocal<v8::Value> runInAsyncScope(v8::Local<v8::Object> target,
+ const char* method,
+ int argc,
+ v8::Local<v8::Value>* argv);
+};
+```
+
+* `name`: Identifier for the kind of resource that is being provided for diagnostics information exposed by the [async_hooks][]
+ API. This will be passed to the possible `init` hook as the `type`. To avoid name collisions with other modules we recommend
+ that the name include the name of the owning module as a prefix. For example `mysql` module could use something like
+ `mysql:batch-db-query-resource`.
+* `resource`: An optional object associated with the async work that will be passed to the possible [async_hooks][]
+ `init` hook. If this parameter is omitted, or an empty handle is provided, this object will be created automatically.
+* When calling JS on behalf of this resource, one can use `runInAsyncScope`. This will ensure that the callback runs in the
+ correct async execution context.
+* `AsyncDestroy` is automatically called when an AsyncResource object is destroyed.
+
+For more details, see the Node [async_hooks][] documentation. You might also want to take a look at the documentation for the
+[N-API counterpart][napi]. For example usage, see the `asyncresource.cpp` example in the `test/cpp` directory.
+
+<a name="api_nan_make_callback"></a>
+### Nan::MakeCallback()
+
+Deprecated wrappers around the legacy `node::MakeCallback()` APIs. Node.js 10+
+has deprecated these legacy APIs as they do not provide a mechanism to preserve
+async context.
+
+We recommend that you use the `AsyncResource` class and `AsyncResource::runInAsyncScope` instead of using `Nan::MakeCallback` or
+`v8::Function#Call()` directly. `AsyncResource` properly takes care of running the callback in the correct async execution
+context – something that is essential for functionality like domains, async_hooks and async debugging.
+
+Signatures:
+
+```c++
+NAN_DEPRECATED
+v8::Local<v8::Value> Nan::MakeCallback(v8::Local<v8::Object> target,
+ v8::Local<v8::Function> func,
+ int argc,
+ v8::Local<v8::Value>* argv);
+NAN_DEPRECATED
+v8::Local<v8::Value> Nan::MakeCallback(v8::Local<v8::Object> target,

+ const char* method,
+ int argc,
+ v8::Local<v8::Value>* argv);
+```
+
+
+<a name="api_nan_module_init"></a>
+### NAN_MODULE_INIT()
+
+Used to define the entry point function to a Node add-on. Creates a function with a given `name` that receives a `target` object representing the equivalent of the JavaScript `exports` object.
+
+See example below.
+
+<a name="api_nan_export"></a>
+### Nan::Export()
+
+A simple helper to register a `v8::FunctionTemplate` from a JavaScript-accessible method (see [Methods](./methods.md)) as a property on an object. Can be used in a way similar to assigning properties to `module.exports` in JavaScript.
+
+Signature:
+
+```c++
+void Export(v8::Local<v8::Object> target, const char *name, Nan::FunctionCallback f)
+```
+
+Also available as the shortcut `NAN_EXPORT` macro.
+
+Example:
+
+```c++
+NAN_METHOD(Foo) {
+ ...
+}
+
+NAN_MODULE_INIT(Init) {
+ NAN_EXPORT(target, Foo);
+}

+## Object Wrappers
+
+The `ObjectWrap` class can be used to make wrapped C++ objects and a factory of wrapped objects.

+### Nan::ObjectWrap()
+
+A reimplementation of `node::ObjectWrap` that adds some API not present in older versions of Node. Should be preferred over `node::ObjectWrap` in all cases for consistency.
+
+Definition:

+```c++
+class ObjectWrap {
+ public:
+ ObjectWrap();
+
+ virtual ~ObjectWrap();
+
+ template <class T>
+ static inline T* Unwrap(v8::Local<v8::Object> handle);

+ virtual void Ref();
+
+ /* Unref() marks an object as detached from the event loop. This is its

+ * (A "weak reference" means an object that only has a
+ * persistent handle.)
+ *
+ * DO NOT CALL THIS FROM DESTRUCTOR
+ */
+ virtual void Unref();
+
+ int refs_; // ro
+};
+```
+
+See the Node documentation on [Wrapping C++ Objects](https://nodejs.org/api/addons.html#addons_wrapping_c_objects) for more details.
+
+### This vs. Holder
+
+When calling `Unwrap`, it is important that the argument is indeed some JavaScript object which got wrapped by a `Wrap` call for this class or any derived class.
+The `Signature` installed by [`Nan::SetPrototypeMethod()`](methods.md#api_nan_set_prototype_method) does ensure that `info.Holder()` is just such an instance.
+In Node 0.12 and later, `info.This()` will also be of such a type, since otherwise the invocation will get rejected.
+However, in Node 0.10 and before it was possible to invoke a method on a JavaScript object which just had the extension type in its prototype chain.
+In such a situation, calling `Unwrap` on `info.This()` will likely lead to a failed assertion causing a crash, but could lead to even more serious corruption.
+
+On the other hand, calling `Unwrap` in an [accessor](methods.md#api_nan_set_accessor) should not use `Holder()` if the accessor is defined on the prototype.
+So either define your accessors on the instance template,
+or use `This()` after verifying that it is indeed a valid object.
+
+### Examples
+
+#### Basic
+
+```c++
+class MyObject : public Nan::ObjectWrap {
+ public:
+ static NAN_MODULE_INIT(Init) {
+ v8::Local<v8::FunctionTemplate> tpl = Nan::New<v8::FunctionTemplate>(New);
+ tpl->SetClassName(Nan::New("MyObject").ToLocalChecked());
+ tpl->InstanceTemplate()->SetInternalFieldCount(1);
+
+ Nan::SetPrototypeMethod(tpl, "getHandle", GetHandle);
+ Nan::SetPrototypeMethod(tpl, "getValue", GetValue);
+
+ constructor().Reset(Nan::GetFunction(tpl).ToLocalChecked());
+ Nan::Set(target, Nan::New("MyObject").ToLocalChecked(),
+ Nan::GetFunction(tpl).ToLocalChecked());
+ }
+
+ private:
+ explicit MyObject(double value = 0) : value_(value) {}
+ ~MyObject() {}
+
+ static NAN_METHOD(New) {
+ if (info.IsConstructCall()) {
+ double value = info[0]->IsUndefined() ? 0 : Nan::To<double>(info[0]).FromJust();
+ MyObject *obj = new MyObject(value);
+ obj->Wrap(info.This());
+ info.GetReturnValue().Set(info.This());
+ } else {
+ const int argc = 1;
+ v8::Local<v8::Value> argv[argc] = {info[0]};
+ v8::Local<v8::Function> cons = Nan::New(constructor());
+ info.GetReturnValue().Set(Nan::NewInstance(cons, argc, argv).ToLocalChecked());
+ }
+ }
+
+ static NAN_METHOD(GetHandle) {
+ MyObject* obj = Nan::ObjectWrap::Unwrap<MyObject>(info.Holder());
+ info.GetReturnValue().Set(obj->handle());
+ }
+
+ static NAN_METHOD(GetValue) {
+ MyObject* obj = Nan::ObjectWrap::Unwrap<MyObject>(info.Holder());
+ info.GetReturnValue().Set(obj->value_);
+ }
+
+ static inline Nan::Persistent<v8::Function> & constructor() {
+ static Nan::Persistent<v8::Function> my_constructor;
+ return my_constructor;
+ }
+
+ double value_;
+};
+
+NODE_MODULE(objectwrapper, MyObject::Init)
+```
+
+To use in Javascript:
+
+```Javascript
+var objectwrapper = require('bindings')('objectwrapper');
+
+var obj = new objectwrapper.MyObject(5);
+console.log('Should be 5: ' + obj.getValue());
+```
+
+#### Factory of wrapped objects
+
+```c++
+class MyFactoryObject : public Nan::ObjectWrap {
+ public:
+ static NAN_MODULE_INIT(Init) {
+ v8::Local<v8::FunctionTemplate> tpl = Nan::New<v8::FunctionTemplate>(New);
+ tpl->InstanceTemplate()->SetInternalFieldCount(1);
+
+ Nan::SetPrototypeMethod(tpl, "getValue", GetValue);
+
+ constructor().Reset(Nan::GetFunction(tpl).ToLocalChecked());
+ }
+
+ static NAN_METHOD(NewInstance) {
+ v8::Local<v8::Function> cons = Nan::New(constructor());
+ double value = info[0]->IsNumber() ? Nan::To<double>(info[0]).FromJust() : 0;
+ const int argc = 1;
+ v8::Local<v8::Value> argv[1] = {Nan::New(value)};
+ info.GetReturnValue().Set(Nan::NewInstance(cons, argc, argv).ToLocalChecked());
+ }
+
+ // Needed for the next example:
+ inline double value() const {
+ return value_;
+ }
+
+ private:
+ explicit MyFactoryObject(double value = 0) : value_(value) {}
+ ~MyFactoryObject() {}
+
+ static NAN_METHOD(New) {
+ if (info.IsConstructCall()) {
+ double value = info[0]->IsNumber() ? Nan::To<double>(info[0]).FromJust() : 0;
+ MyFactoryObject * obj = new MyFactoryObject(value);
+ obj->Wrap(info.This());
+ info.GetReturnValue().Set(info.This());
+ } else {
+ const int argc = 1;
+ v8::Local<v8::Value> argv[argc] = {info[0]};
+ v8::Local<v8::Function> cons = Nan::New(constructor());
+ info.GetReturnValue().Set(Nan::NewInstance(cons, argc, argv).ToLocalChecked());
+ }
+ }
+
+ static NAN_METHOD(GetValue) {
+ MyFactoryObject* obj = ObjectWrap::Unwrap<MyFactoryObject>(info.Holder());
+ info.GetReturnValue().Set(obj->value_);
+ }
+
+ static inline Nan::Persistent<v8::Function> & constructor() {
+ static Nan::Persistent<v8::Function> my_constructor;
+ return my_constructor;
+ }
+
+ double value_;
+};
+
+NAN_MODULE_INIT(Init) {
+ MyFactoryObject::Init(target);
+ Nan::Set(target,
+ Nan::New<v8::String>("newFactoryObjectInstance").ToLocalChecked(),
+ Nan::GetFunction(
+ Nan::New<v8::FunctionTemplate>(MyFactoryObject::NewInstance)).ToLocalChecked()
+ );
+}
+
+NODE_MODULE(wrappedobjectfactory, Init)
+```
+
+To use in Javascript:
+
+```Javascript
+var wrappedobjectfactory = require('bindings')('wrappedobjectfactory');
+
+var obj = wrappedobjectfactory.newFactoryObjectInstance(10);
+console.log('Should be 10: ' + obj.getValue());
+```
+
+#### Passing wrapped objects around
+
+Use the `MyFactoryObject` class above along with the following:
+
+```c++
+static NAN_METHOD(Sum) {
+ Nan::MaybeLocal<v8::Object> maybe1 = Nan::To<v8::Object>(info[0]);
+ Nan::MaybeLocal<v8::Object> maybe2 = Nan::To<v8::Object>(info[1]);
+

+## Persistent references
+
+An object reference that is independent of any `HandleScope` is a _persistent_ reference. Where a `Local` handle only lives as long as the `HandleScope` in which it was allocated, a `Persistent` handle remains valid until it is explicitly disposed.
+
+Due to the evolution of the V8 API, it is necessary for NAN to provide a wrapper implementation of the `Persistent` classes to supply compatibility across the V8 versions supported.

+### Nan::WeakCallbackInfo
+
+`Nan::WeakCallbackInfo` is used as an argument when setting a persistent reference as weak. You may need to free any external resources attached to the object. It is a mirror of `v8:WeakCallbackInfo` as found in newer versions of V8.
+
+Definition:
+
+```c++
+template<typename T> class WeakCallbackInfo {
+ public:
+ typedef void (*Callback)(const WeakCallbackInfo<T>& data);

+ T *GetParameter() const;
+
+ /**
+ * Get pointer from internal field, index can be 0 or 1.
+ */
+ void *GetInternalField(int index) const;
+};
+```
+
+Example usage:
+
+```c++
+void weakCallback(const WeakCallbackInfo<int> &data) {
+ int *parameter = data.GetParameter();
+ delete parameter;
+}
+
+Persistent<v8::Object> obj;
+int *data = new int(0);
+obj.SetWeak(data, callback, WeakCallbackType::kParameter);
+```
+
+See the V8 documentation for [`WeakCallbackInfo`](https://v8docs.nodesource.com/node-8.16/d8/d06/classv8_1_1_weak_callback_info.html) for further information.
+
+<a name="api_nan_weak_callback_type"></a>
+### Nan::WeakCallbackType
+
+Represents the type of a weak callback.
+A weak callback of type `kParameter` makes the supplied parameter to `Nan::PersistentBase::SetWeak` available through `WeakCallbackInfo::GetParameter`.
+A weak callback of type `kInternalFields` uses up to two internal fields at indices 0 and 1 on the `Nan::PersistentBase<v8::Object>` being made weak.
+Note that only `v8::Object`s and derivatives can have internal fields.
+
+Definition:
+
+```c++

+## Scopes
+
+A _local handle_ is a pointer to an object. All V8 objects are accessed using handles, they are necessary because of the way the V8 garbage collector works.
+
+A handle scope can be thought of as a container for any number of handles. When you've finished with your handles, instead of deleting each one individually you can simply delete their scope.
+
+The creation of `HandleScope` objects is different across the supported versions of V8. Therefore, NAN provides its own implementations that can be used safely across these.
+
+ - <a href="#api_nan_handle_scope"><b><code>Nan::HandleScope</code></b></a>
+ - <a href="#api_nan_escapable_handle_scope"><b><code>Nan::EscapableHandleScope</code></b></a>
+
+Also see the V8 Embedders Guide section on [Handles and Garbage Collection](https://github.com/v8/v8/wiki/Embedder%27s%20Guide#handles-and-garbage-collection).
+
+<a name="api_nan_handle_scope"></a>
+### Nan::HandleScope
+
+A simple wrapper around [`v8::HandleScope`](https://v8docs.nodesource.com/node-8.16/d3/d95/classv8_1_1_handle_scope.html).
+
+Definition:
+
+```c++
+class Nan::HandleScope {
+ public:
+ Nan::HandleScope();
+ static int NumberOfHandles();
+};
+```
+
+Allocate a new `Nan::HandleScope` whenever you are creating new V8 JavaScript objects. Note that an implicit `HandleScope` is created for you on JavaScript-accessible methods so you do not need to insert one yourself.
+
+Example:
+
+```c++
+// new object is created, it needs a new scope:
+void Pointless() {
+ Nan::HandleScope scope;
+ v8::Local<v8::Object> obj = Nan::New<v8::Object>();
+}
+
+// JavaScript-accessible method already has a HandleScope
+NAN_METHOD(Pointless2) {
+ v8::Local<v8::Object> obj = Nan::New<v8::Object>();
+}
+```
+
+<a name="api_nan_escapable_handle_scope"></a>
+### Nan::EscapableHandleScope
+
+Similar to [`Nan::HandleScope`](#api_nan_handle_scope) but should be used in cases where a function needs to return a V8 JavaScript type that has been created within it.
+
+Definition:
+
+```c++
+class Nan::EscapableHandleScope {
+ public:
+ Nan::EscapableHandleScope();
+ static int NumberOfHandles();
+ template<typename T> v8::Local<T> Escape(v8::Local<T> value);
+}
+```
+
+Use `Escape(value)` to return the object.
+
+Example:
+
+```c++
+v8::Local<v8::Object> EmptyObj() {
+ Nan::EscapableHandleScope scope;
+ v8::Local<v8::Object> obj = Nan::New<v8::Object>();
+ return scope.Escape(obj);
+}
+```

+### Nan::Utf8String
+
+Converts an object to a UTF-8-encoded character array. If conversion to a string fails (e.g. due to an exception in the toString() method of the object) then the length() method returns 0 and the * operator returns NULL. The underlying memory used for this object is managed by the object.
+
+An implementation of [`v8::String::Utf8Value`](https://v8docs.nodesource.com/node-8.16/d4/d1b/classv8_1_1_string_1_1_utf8_value.html) that is consistent across all supported versions of V8.
+
+Definition:
+
+```c++
+class Nan::Utf8String {
+ public:
+ Nan::Utf8String(v8::Local<v8::Value> from);
+
+ int length() const;
+
+ char* operator*();
+ const char* operator*() const;
+};
+```
+

+
+Signature:

+```c++
+v8::Local<v8::Context> Nan::GetCurrentContext()
+```
+
+<a name="api_nan_set_isolate_data"></a>
+### Nan::SetIsolateData()
+
+A helper to provide a consistent API to [`v8::Isolate#SetData()`](https://v8docs.nodesource.com/node-8.16/d5/dda/classv8_1_1_isolate.html#a7acadfe7965997e9c386a05f098fbe36).

+```
+
+
+<a name="api_nan_get_isolate_data"></a>
+### Nan::GetIsolateData()
+
+A helper to provide a consistent API to [`v8::Isolate#GetData()`](https://v8docs.nodesource.com/node-8.16/d5/dda/classv8_1_1_isolate.html#aabd223436bc1100a787dadaa024c6257).

+```c++
+T *Nan::GetIsolateData(v8::Isolate *isolate)
+```
+
+<a name="api_nan_typedarray_contents"></a>
+### Nan::TypedArrayContents<T>
+
+A helper class for accessing the contents of an ArrayBufferView (aka a typedarray) from C++. If the input array is not a valid typedarray, then the data pointer of TypedArrayContents will default to `NULL` and the length will be 0. If the data pointer is not compatible with the alignment requirements of type, an assertion error will fail.
+
+Note that you must store a reference to the `array` object while you are accessing its contents.
+
+Definition:
+
+```c++
+template<typename T>
+class Nan::TypedArrayContents {
+ public:
+ TypedArrayContents(v8::Local<Value> array);
+
+ size_t length() const;
+
+ T* const operator*();
+ const T* const operator*() const;
+};

+
+A set of utilities to assist developers of tools that build [N-API](https://nodejs.org/api/n-api.html#n_api_n_api) native add-ons.
+
+## Background
+
+This module is targeted to developers creating tools that build N-API native add-ons.
+
+It implements a set of functions that aid in determining the N-API version supported by the currently running Node instance and the set of N-API versions against which the N-API native add-on is designed to be built. Other functions determine whether a particular N-API version can be built and can issue console warnings for unsupported N-API versions.
+
+Unlike the modules this code is designed to facilitate building, this module is written entirely in JavaScript.
+
+## Quick start
+
+```bash
+$ npm install napi-build-utils
+```
+
+The module exports a set of functions documented [here](./index.md). For example:
+
+```javascript
+var napiBuildUtils = require('napi-build-utils');
+var napiVersion = napiBuildUtils.getNapiVersion(); // N-API version supported by Node, or undefined.
+```
+
+## Declaring supported N-API versions
+
+Native modules that are designed to work with [N-API](https://nodejs.org/api/n-api.html#n_api_n_api) must explicitly declare the N-API version(s) against which they are coded to build. This is accomplished by including a `binary.napi_versions` property in the module's `package.json` file. For example:
+
+```json
+"binary": {
+ "napi_versions": [2,3]
+}
+```
+
+In the absence of a need to compile against a specific N-API version, the value `3` is a good choice as this is the N-API version that was supported when N-API left experimental status.
+
+Modules that are built against a specific N-API version will continue to operate indefinitely, even as later versions of N-API are introduced.
+
+## Support
+
+If you run into problems or limitations, please file an issue and we'll take a look. Pull requests are also welcome.

+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as
+contributors and maintainers pledge to making participation in our project and
+our community a harassment-free experience for everyone, regardless of age, body
+size, disability, ethnicity, gender identity and expression, level of experience,
+nationality, personal appearance, race, religion, or sexual identity and
+orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment
+include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or
+ advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic
+ address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+ professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable
+behavior and are expected to take appropriate and fair corrective action in
+response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or
+reject comments, commits, code, wiki edits, issues, and other contributions
+that are not aligned to this Code of Conduct, or to ban temporarily or
+permanently any contributor for other behaviors that they deem inappropriate,
+threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces
+when an individual is representing the project or its community. Examples of
+representing a project or community include using an official project e-mail
+address, posting via an official social media account, or acting as an appointed
+representative at an online or offline event. Representation of a project may be
+further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported by contacting the project team at lukas.geiger94@gmail.com. All
+complaints will be reviewed and investigated and will result in a response that
+is deemed necessary and appropriate to the circumstances. The project team is
+obligated to maintain confidentiality with regard to the reporter of an incident.
+Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good
+faith may face temporary or permanent repercussions as determined by other
+members of the project's leadership.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,
+available at https://www.contributor-covenant.org/version/1/4/code-of-conduct/

+# Contributing to `node-abi`
+
+:+1::tada: First off, thanks for taking the time to contribute to `node-abi`! :tada::+1:
+
+## Commit Message Guidelines
+
+This module uses [`semantic-release`](https://github.com/semantic-release/semantic-release) to automatically release new versions via Travis.
+Therefor we have very precise rules over how our git commit messages can be formatted.
+
+Each commit message consists of a **header**, a **body** and a **footer**. The header has a special
+format that includes a **type**, a **scope** and a **subject** ([full explanation](https://github.com/stevemao/conventional-changelog-angular/blob/master/convention.md)):
+
+```
+<type>(<scope>): <subject>
+<BLANK LINE>
+<body>
+<BLANK LINE>
+<footer>
+```
+
+### Type
+
+Must be one of the following:
+
+- **feat**: A new feature. **Will trigger a new release**
+- **fix**: A bug fix or a addition to one of the target arrays. **Will trigger a new release**
+- **docs**: Documentation only changes
+- **style**: Changes that do not affect the meaning of the code (white-space, formatting, missing semi-colons, etc)
+- **refactor**: A code change that neither fixes a bug nor adds a feature
+- **perf**: A code change that improves performance
+- **test**: Adding missing or correcting existing tests
+- **chore**: Changes to the build process or auxiliary tools and libraries such as documentation generation
+
+
+### Patch Release
+
+```
+fix(electron): Support Electron 1.8.0
+```
+
+### ~~Minor~~ Feature Release
+
+```
+feat: add .getTarget(abi, runtime)
+```
+
+### ~~Major~~ Breaking Release
+
+```
+feat: Add amazing new feature
+
+BREAKING CHANGE: This removes support for Node 0.10 and 0.12.
+```

+### v4.0.2
+
+* Added installation instructions.
+
+### v4.0.1
+
+* Fix bugs where `log.progressEnabled` got out of sync with how `gauge` kept
+ track of these things resulting in a progressbar that couldn't be disabled.
+
+### v4.0.0
+
+* Allow creating log levels that are an empty string or 0.
+
+### v3.1.2
+
+* Update to `gauge@1.6.0` adding support for default values for template
+ items.
+
+### v3.1.1
+
+* Update to `gauge@1.5.3` to fix to `1.x` compatibility when it comes to
+ when a progress bar is enabled. In `1.x` if you didn't have a TTY the
+ progress bar was never shown. In `2.x` it merely defaults to disabled,
+ but you can enable it explicitly if you still want progress updates.
+
+### v3.1.0
+
+* Update to `gauge@2.5.2`:
+ * Updates the `signal-exit` dependency which fixes an incompatibility with
+ the node profiler.
+ * Uses externalizes its ansi code generation in `console-control-strings`
+* Make the default progress bar include the last line printed, colored as it
+ would be when printing to a tty.
+
+### v3.0.0
+
+* Switch to `gauge@2.0.0`, for better performance, better look.
+* Set stderr/stdout blocking if they're tty's, so that we can hide a
+ progress bar going to stderr and then safely print to stdout. Without
+ this the two can end up overlapping producing confusing and sometimes
+ corrupted output.
+
+### v2.0.0
+
+* Make the `error` event non-fatal so that folks can use it as a prefix.
+
+### v1.0.0
+
+* Add progress bar with `gauge@1.1.0`

+# npmlog
+
+The logger util that npm uses.
+
+This logger is very basic. It does the logging for npm. It supports
+custom levels and colored output.
+
+By default, logs are written to stderr. If you want to send log messages
+to outputs other than streams, then you can change the `log.stream`
+member, or you can just listen to the events that it emits, and do
+whatever you want with them.
+
+# Installation
+
+```console
+npm install npmlog --save
+```
+
+# Basic Usage
+
+```javascript
+var log = require('npmlog')
+
+// additional stuff ---------------------------+
+// message ----------+ |
+// prefix ----+ | |
+// level -+ | | |
+// v v v v
+ log.info('fyi', 'I have a kitty cat: %j', myKittyCat)
+```
+
+## log.level
+
+* {String}
+
+The level to display logs at. Any logs at or above this level will be
+displayed. The special level `silent` will prevent anything from being
+displayed ever.
+
+## log.record
+
+* {Array}
+
+An array of all the log messages that have been entered.
+
+## log.maxRecordSize
+
+* {Number}
+
+The maximum number of records to keep. If log.record gets bigger than
+10% over this value, then it is sliced down to 90% of this value.
+
+The reason for the 10% window is so that it doesn't have to resize a
+large array on every log entry.
+
+## log.prefixStyle
+
+* {Object}
+
+A style object that specifies how prefixes are styled. (See below)
+
+## log.headingStyle
+
+* {Object}
+
+A style object that specifies how the heading is styled. (See below)
+
+## log.heading
+
+* {String} Default: ""
+
+If set, a heading that is printed at the start of every line.
+
+## log.stream
+
+* {Stream} Default: `process.stderr`
+
+The stream where output is written.
+
+## log.enableColor()
+
+Force colors to be used on all messages, regardless of the output
+stream.
+
+## log.disableColor()
+
+Disable colors on all messages.
+
+## log.enableProgress()
+
+Enable the display of log activity spinner and progress bar
+
+## log.disableProgress()
+
+Disable the display of a progress bar
+
+## log.enableUnicode()
+
+Force the unicode theme to be used for the progress bar.
+
+## log.disableUnicode()
+
+Disable the use of unicode in the progress bar.
+
+## log.setGaugeTemplate(template)
+
+Set a template for outputting the progress bar. See the [gauge documentation] for details.
+
+[gauge documentation]: https://npmjs.com/package/gauge
+
+## log.setGaugeThemeset(themes)
+
+Select a themeset to pick themes from for the progress bar. See the [gauge documentation] for details.
+
+## log.pause()
+
+Stop emitting messages to the stream, but do not drop them.
+
+## log.resume()
+
+Emit all buffered messages that were written while paused.
+
+## log.log(level, prefix, message, ...)
+
+* `level` {String} The level to emit the message at
+* `prefix` {String} A string prefix. Set to "" to skip.
+* `message...` Arguments to `util.format`
+
+Emit a log message at the specified level.
+
+## log\[level](prefix, message, ...)
+
+For example,
+
+* log.silly(prefix, message, ...)
+* log.verbose(prefix, message, ...)
+* log.info(prefix, message, ...)
+* log.http(prefix, message, ...)
+* log.warn(prefix, message, ...)
+* log.error(prefix, message, ...)
+
+Like `log.log(level, prefix, message, ...)`. In this way, each level is
+given a shorthand, so you can do `log.info(prefix, message)`.
+
+## log.addLevel(level, n, style, disp)
+
+* `level` {String} Level indicator
+* `n` {Number} The numeric level
+* `style` {Object} Object with fg, bg, inverse, etc.
+* `disp` {String} Optional replacement for `level` in the output.
+
+Sets up a new level with a shorthand function and so forth.
+
+Note that if the number is `Infinity`, then setting the level to that
+will cause all log messages to be suppressed. If the number is
+`-Infinity`, then the only way to show it is to enable all log messages.
+
+## log.newItem(name, todo, weight)
+
+* `name` {String} Optional; progress item name.
+* `todo` {Number} Optional; total amount of work to be done. Default 0.
+* `weight` {Number} Optional; the weight of this item relative to others. Default 1.
+
+This adds a new `are-we-there-yet` item tracker to the progress tracker. The
+object returned has the `log[level]` methods but is otherwise an
+`are-we-there-yet` `Tracker` object.
+
+## log.newStream(name, todo, weight)
+
+This adds a new `are-we-there-yet` stream tracker to the progress tracker. The
+object returned has the `log[level]` methods but is otherwise an
+`are-we-there-yet` `TrackerStream` object.
+
+## log.newGroup(name, weight)
+
+This adds a new `are-we-there-yet` tracker group to the progress tracker. The
+object returned has the `log[level]` methods but is otherwise an
+`are-we-there-yet` `TrackerGroup` object.
+
+# Events
+
+Events are all emitted with the message object.
+
+* `log` Emitted for all messages
+* `log.<level>` Emitted for all messages with the `<level>` level.
+* `<prefix>` Messages with prefixes also emit their prefix as an event.
+
+# Style Objects
+
+Style objects can have the following fields:
+
+* `fg` {String} Color for the foreground text
+* `bg` {String} Color for the background
+* `bold`, `inverse`, `underline` {Boolean} Set the associated property
+* `bell` {Boolean} Make a noise (This is pretty annoying, probably.)
+
+# Message Objects
+
+Every log event is emitted with a message object, and the `log.record`
+list contains all of them that have been created. They have the
+following fields:
+
+* `id` {Number}
+* `level` {String}
+* `prefix` {String}
+* `message` {String} Result of `util.format()`
+* `messageRaw` {Array} Arguments to `util.format()`
+
+# Blocking TTYs
+
+We use [`set-blocking`](https://npmjs.com/package/set-blocking) to set
+stderr and stdout blocking if they are tty's and have the setBlocking call.
+This is a work around for an issue in early versions of Node.js 6.x, which
+made stderr and stdout non-blocking on OSX. (They are always blocking
+Windows and were never blocking on Linux.) `npmlog` needs them to be blocking
+so that it can allow output to stdout and stderr to be interlaced.

+## Use the built-in
+
+Node.js 4 and up, as well as every evergreen browser (Chrome, Edge, Firefox, Opera, Safari),
+support `Object.assign()` :tada:. If you target only those environments, then by all
+means, use `Object.assign()` instead of this package.
+
+
+## Install
+
+```
+$ npm install --save object-assign
+```
+
+
+## Usage
+
+```js
+const objectAssign = require('object-assign');
+
+objectAssign({foo: 0}, {bar: 1});
+//=> {foo: 0, bar: 1}
+
+// multiple sources
+objectAssign({foo: 0}, {bar: 1}, {baz: 2});

+
+// overwrites equal keys
+objectAssign({foo: 0}, {foo: 1}, {foo: 2});
+//=> {foo: 2}
+
+// ignores null and undefined sources
+objectAssign({foo: 0}, null, {bar: 1}, undefined);
+//=> {foo: 0, bar: 1}
+```
+
+
+## API
+
+### objectAssign(target, [source, ...])
+
+Assigns enumerable own properties of `source` objects to the `target` object and returns the `target` object. Additional `source` objects will overwrite previous ones.

+# once
+
+Only call a function once.
+
+## usage
+
+```javascript
+var once = require('once')
+
+function load (file, cb) {
+ cb = once(cb)
+ loader.load('file')
+ loader.once('load', cb)
+ loader.once('error', cb)
+}
+```
+
+Or add to the Function.prototype in a responsible way:
+
+```javascript
+// only has to be done once
+require('once').proto()
+
+function load (file, cb) {
+ cb = cb.once()
+ loader.load('file')
+ loader.once('load', cb)
+ loader.once('error', cb)
+}
+```
+
+Ironically, the prototype feature makes this module twice as
+complicated as necessary.
+
+To check whether you function has been called, use `fn.called`. Once the
+function is called for the first time the return value of the original
+function is saved in `fn.value` and subsequent calls will continue to
+return this value.
+
+```javascript
+var once = require('once')
+
+function load (cb) {
+ cb = once(cb)
+ var stream = createStream()
+ stream.once('data', cb)
+ stream.once('end', function () {
+ if (!cb.called) cb(new Error('not found'))
+ })
+}
+```
+
+## `once.strict(func)`
+
+Throw an error if the function is called twice.
+
+Some functions are expected to be called only once. Using `once` for them would
+potentially hide logical errors.
+
+In the example below, the `greet` function has to call the callback only once:
+
+```javascript
+function greet (name, cb) {
+ // return is missing from the if statement
+ // when no name is passed, the callback is called twice
+ if (!name) cb('Hello anonymous')
+ cb('Hello ' + name)
+}
+
+function log (msg) {
+ console.log(msg)
+}
+
+// this will print 'Hello anonymous' but the logical error will be missed
+greet(null, once(msg))
+
+// once.strict will print 'Hello anonymous' and throw an error when the callback will be called the second time
+greet(null, once.strict(msg))
+```

+# prebuild-install
+
+> A command line tool to easily install prebuilt binaries for multiple version of node/iojs on a specific platform.
+
+[](https://www.npmjs.com/package/prebuild-install)
+
+[](https://travis-ci.org/prebuild/prebuild-install)
+[](https://ci.appveyor.com/project/mathiask88/prebuild-install)
+[](https://david-dm.org/prebuild/prebuild-install)
+[](http://standardjs.com/)
+
+`prebuild-install` supports installing prebuilt binaries from GitHub by default.
+
+## Usage
+
+Change your package.json install script to:
+
+```json
+{
+ "scripts": {
+ "install": "prebuild-install || node-gyp rebuild"
+ }
+}
+```
+
+### Requirements
+
+You need to provide prebuilds made by [`prebuild`](https://github.com/prebuild/prebuild).
+
+### Help
+
+```
+prebuild-install [options]
+
+ --download -d [url] (download prebuilds, no url means github)
+ --target -t version (version to install for)
+ --runtime -r runtime (Node runtime [node, napi or electron] to build or install for, default is node)
+ --path -p path (make a prebuild-install here)
+ --token -T gh-token (github token for private repos)
+ --arch arch (target CPU architecture, see Node OS module docs, default is current arch)
+ --platform platform (target platform, see Node OS module docs, default is current platform)
+ --tag-prefix <prefix> (github tag prefix, default is "v")
+ --build-from-source (skip prebuild download)
+ --verbose (log verbosely)
+ --libc (use provided libc rather than system default)
+ --debug (set Debug or Release configuration)
+ --version (print prebuild-install version and exit)
+```
+
+When `prebuild-install` is run via an `npm` script, options
+`--build-from-source`, `--debug`, `--download`, `--target`, `--runtime`, `--arch` and `--platform` may be passed through via
+arguments given to the `npm` command. Alternatively you can set environment variables `npm_config_build_from_source=true`, `npm_config_platform`, `npm_config_arch`, `npm_config_target` and `npm_config_runtime`.
+
+### Private Repositories
+
+`prebuild-install` supports downloading prebuilds from private GitHub repositories using the `-T <github-token>`:
+
+```
+$ prebuild-install -T <github-token>
+```
+
+If you don't want to use the token on cli you can put it in `~/.prebuild-installrc`:
+
+```
+token=<github-token>
+```
+
+Alternatively you can specify it in the `prebuild-install_token` environment variable.
+
+Note that using a GitHub token uses the API to resolve the correct release meaning that you are subject to the ([GitHub Rate Limit](https://developer.github.com/v3/rate_limit/)).
+
+### Create GitHub Token
+
+To create a token:
+
+- Go to [this page](https://github.com/settings/tokens)
+- Click the `Generate new token` button
+- Give the token a name and click the `Generate token` button, see below
+
+
+
+The default scopes should be fine.
+
+### Custom binaries
+
+The end user can override binary download location through environment variables in their .npmrc file.
+The variable needs to meet the mask `% your package name %_binary_host` or `% your package name %_binary_host_mirror`. For example:
+
+```
+leveldown_binary_host=http://overriden-host.com/overriden-path
+```
+
+Note that the package version subpath and file name will still be appended.
+So if you are installing `leveldown@1.2.3` the resulting url will be:
+
+```
+http://overriden-host.com/overriden-path/v1.2.3/leveldown-v1.2.3-node-v57-win32-x64.tar.gz
+```
+
+### Cache
+
+All prebuilt binaries are cached to minimize traffic. So first `prebuild-install` picks binaries from the cache and if no binary could be found, it will be downloaded. Depending on the environment, the cache folder is determined in the following order:
+
+- `${npm_config_cache}/_prebuilds`
+- `${APP_DATA}/npm-cache/_prebuilds`
+- `${HOME}/.npm/_prebuilds`

+# pump
+
+pump is a small node module that pipes streams together and destroys all of them if one of them closes.
+
+```
+npm install pump
+```
+
+[](http://travis-ci.org/mafintosh/pump)
+
+## What problem does it solve?
+
+When using standard `source.pipe(dest)` source will _not_ be destroyed if dest emits close or an error.
+You are also not able to provide a callback to tell when then pipe has finished.
+
+pump does these two things for you
+
+## Usage
+
+Simply pass the streams you want to pipe together to pump and add an optional callback
+
+``` js
+var pump = require('pump')
+var fs = require('fs')
+
+var source = fs.createReadStream('/dev/random')
+var dest = fs.createWriteStream('/dev/null')
+
+pump(source, dest, function(err) {
+ console.log('pipe finished', err)
+})
+
+setTimeout(function() {
+ dest.destroy() // when dest is closed pump will destroy source
+}, 1000)
+```
+
+You can use pump to pipe more than two streams together as well
+
+``` js
+var transform = someTransformStream()
+
+pump(source, transform, anotherTransform, dest, function(err) {
+ console.log('pipe finished', err)
+})
+```
+
+If `source`, `transform`, `anotherTransform` or `dest` closes all of them will be destroyed.
+
+Similarly to `stream.pipe()`, `pump()` returns the last stream passed in, so you can do:
+
+```
+return pump(s1, s2) // returns s2
+```
+
+If you want to return a stream that combines *both* s1 and s2 to a single stream use
+[pumpify](https://github.com/mafintosh/pumpify) instead.

+`pump` is part of the [mississippi stream utility collection](https://github.com/maxogden/mississippi) which includes more useful stream modules similar to this one.

+# rc
+
+The non-configurable configuration loader for lazy people.
+
+## Usage
+
+The only option is to pass rc the name of your app, and your default configuration.
+
+```javascript
+var conf = require('rc')(appname, {
+ //defaults go here.
+ port: 2468,
+
+ //defaults which are objects will be merged, not replaced
+ views: {
+ engine: 'jade'
+ }
+});
+```
+
+`rc` will return your configuration options merged with the defaults you specify.
+If you pass in a predefined defaults object, it will be mutated:
+
+```javascript
+var conf = {};
+require('rc')(appname, conf);
+```
+
+If `rc` finds any config files for your app, the returned config object will have
+a `configs` array containing their paths:
+
+```javascript
+var appCfg = require('rc')(appname, conf);
+appCfg.configs[0] // /etc/appnamerc
+appCfg.configs[1] // /home/dominictarr/.config/appname
+appCfg.config // same as appCfg.configs[appCfg.configs.length - 1]
+```
+
+## Standards
+
+Given your application name (`appname`), rc will look in all the obvious places for configuration.
+
+ * command line arguments, parsed by minimist _(e.g. `--foo baz`, also nested: `--foo.bar=baz`)_
+ * environment variables prefixed with `${appname}_`
+ * or use "\_\_" to indicate nested properties <br/> _(e.g. `appname_foo__bar__baz` => `foo.bar.baz`)_
+ * if you passed an option `--config file` then from that file
+ * a local `.${appname}rc` or the first found looking in `./ ../ ../../ ../../../` etc.
+ * `$HOME/.${appname}rc`
+ * `$HOME/.${appname}/config`
+ * `$HOME/.config/${appname}`
+ * `$HOME/.config/${appname}/config`
+ * `/etc/${appname}rc`
+ * `/etc/${appname}/config`
+ * the defaults object you passed in.
+
+All configuration sources that were found will be flattened into one object,
+so that sources **earlier** in this list override later ones.
+
+
+## Configuration File Formats
+
+Configuration files (e.g. `.appnamerc`) may be in either [json](http://json.org/example) or [ini](http://en.wikipedia.org/wiki/INI_file) format. **No** file extension (`.json` or `.ini`) should be used. The example configurations below are equivalent:
+
+
+#### Formatted as `ini`
+
+```
+; You can include comments in `ini` format if you want.
+
+dependsOn=0.10.0
+
+
+; `rc` has built-in support for ini sections, see?
+
+[commands]
+ www = ./commands/www
+ console = ./commands/repl
+
+
+; You can even do nested sections
+
+[generators.options]
+ engine = ejs
+
+[generators.modules]
+ new = generate-new
+ engine = generate-backend
+
+```
+
+#### Formatted as `json`
+
+```javascript
+{
+ // You can even comment your JSON, if you want
+ "dependsOn": "0.10.0",
+ "commands": {
+ "www": "./commands/www",
+ "console": "./commands/repl"
+ },
+ "generators": {
+ "options": {
+ "engine": "ejs"
+ },
+ "modules": {
+ "new": "generate-new",
+ "backend": "generate-backend"
+ }
+ }
+}
+```
+
+Comments are stripped from JSON config via [strip-json-comments](https://github.com/sindresorhus/strip-json-comments).
+
+> Since ini, and env variables do not have a standard for types, your application needs be prepared for strings.
+
+To ensure that string representations of booleans and numbers are always converted into their proper types (especially useful if you intend to do strict `===` comparisons), consider using a module such as [parse-strings-in-object](https://github.com/anselanza/parse-strings-in-object) to wrap the config object returned from rc.
+
+
+## Simple example demonstrating precedence
+Assume you have an application like this (notice the hard-coded defaults passed to rc):
+```
+const conf = require('rc')('myapp', {
+ port: 12345,
+ mode: 'test'
+});
+
+console.log(JSON.stringify(conf, null, 2));
+```
+You also have a file `config.json`, with these contents:
+```
+{
+ "port": 9000,
+ "foo": "from config json",
+ "something": "else"
+}
+```
+And a file `.myapprc` in the same folder, with these contents:
+```
+{
+ "port": "3001",
+ "foo": "bar"
+}
+```
+Here is the expected output from various commands:
+
+`node .`
+```
+{
+ "port": "3001",
+ "mode": "test",
+ "foo": "bar",
+ "_": [],
+ "configs": [
+ "/Users/stephen/repos/conftest/.myapprc"
+ ],
+ "config": "/Users/stephen/repos/conftest/.myapprc"
+}
+```
+*Default `mode` from hard-coded object is retained, but port is overridden by `.myapprc` file (automatically found based on appname match), and `foo` is added.*
+
+
+`node . --foo baz`
+```
+{
+ "port": "3001",
+ "mode": "test",
+ "foo": "baz",
+ "_": [],
+ "configs": [
+ "/Users/stephen/repos/conftest/.myapprc"
+ ],
+ "config": "/Users/stephen/repos/conftest/.myapprc"
+}
+```
+*Same result as above but `foo` is overridden because command-line arguments take precedence over `.myapprc` file.*
+
+`node . --foo barbar --config config.json`
+```
+{
+ "port": 9000,
+ "mode": "test",
+ "foo": "barbar",
+ "something": "else",
+ "_": [],
+ "config": "config.json",
+ "configs": [
+ "/Users/stephen/repos/conftest/.myapprc",
+ "config.json"
+ ]
+}
+```
+*Now the `port` comes from the `config.json` file specified (overriding the value from `.myapprc`), and `foo` value is overriden by command-line despite also being specified in the `config.json` file.*
+
+
+
+## Advanced Usage
+
+#### Pass in your own `argv`
+
+You may pass in your own `argv` as the third argument to `rc`. This is in case you want to [use your own command-line opts parser](https://github.com/dominictarr/rc/pull/12).
+
+```javascript
+require('rc')(appname, defaults, customArgvParser);
+```
+
+## Pass in your own parser
+
+If you have a special need to use a non-standard parser,
+you can do so by passing in the parser as the 4th argument.
+(leave the 3rd as null to get the default args parser)
+
+```javascript
+require('rc')(appname, defaults, null, parser);
+```
+
+This may also be used to force a more strict format,
+such as strict, valid JSON only.
+
+## Note on Performance
+
+`rc` is running `fs.statSync`-- so make sure you don't use it in a hot code path (e.g. a request handler)

+### Streams Working Group
+
+The Node.js Streams is jointly governed by a Working Group
+(WG)
+that is responsible for high-level guidance of the project.
+
+The WG has final authority over this project including:
+
+* Technical direction
+* Project governance and process (including this policy)
+* Contribution policy
+* GitHub repository hosting
+* Conduct guidelines
+* Maintaining the list of additional Collaborators
+
+For the current list of WG members, see the project
+[README.md](./README.md#current-project-team-members).
+
+### Collaborators
+
+The readable-stream GitHub repository is
+maintained by the WG and additional Collaborators who are added by the
+WG on an ongoing basis.
+
+Individuals making significant and valuable contributions are made
+Collaborators and given commit-access to the project. These
+individuals are identified by the WG and their addition as
+Collaborators is discussed during the WG meeting.
+
+_Note:_ If you make a significant contribution and are not considered
+for commit-access log an issue or contact a WG member directly and it
+will be brought up in the next WG meeting.
+
+Modifications of the contents of the readable-stream repository are
+made on
+a collaborative basis. Anybody with a GitHub account may propose a
+modification via pull request and it will be considered by the project
+Collaborators. All pull requests must be reviewed and accepted by a
+Collaborator with sufficient expertise who is able to take full
+responsibility for the change. In the case of pull requests proposed
+by an existing Collaborator, an additional Collaborator is required
+for sign-off. Consensus should be sought if additional Collaborators
+participate and there is disagreement around a particular
+modification. See _Consensus Seeking Process_ below for further detail
+on the consensus model used for governance.
+
+Collaborators may opt to elevate significant or controversial
+modifications, or modifications that have not found consensus to the
+WG for discussion by assigning the ***WG-agenda*** tag to a pull
+request or issue. The WG should serve as the final arbiter where
+required.
+
+For the current list of Collaborators, see the project
+[README.md](./README.md#members).
+
+### WG Membership
+
+WG seats are not time-limited. There is no fixed size of the WG.
+However, the expected target is between 6 and 12, to ensure adequate
+coverage of important areas of expertise, balanced with the ability to
+make decisions efficiently.
+
+There is no specific set of requirements or qualifications for WG
+membership beyond these rules.
+
+The WG may add additional members to the WG by unanimous consensus.
+
+A WG member may be removed from the WG by voluntary resignation, or by
+unanimous consensus of all other WG members.
+
+Changes to WG membership should be posted in the agenda, and may be
+suggested as any other agenda item (see "WG Meetings" below).
+
+If an addition or removal is proposed during a meeting, and the full
+WG is not in attendance to participate, then the addition or removal
+is added to the agenda for the subsequent meeting. This is to ensure
+that all members are given the opportunity to participate in all
+membership decisions. If a WG member is unable to attend a meeting
+where a planned membership decision is being made, then their consent
+is assumed.
+
+No more than 1/3 of the WG members may be affiliated with the same
+employer. If removal or resignation of a WG member, or a change of
+employment by a WG member, creates a situation where more than 1/3 of
+the WG membership shares an employer, then the situation must be
+immediately remedied by the resignation or removal of one or more WG
+members affiliated with the over-represented employer(s).
+
+### WG Meetings
+
+The WG meets occasionally on a Google Hangout On Air. A designated moderator
+approved by the WG runs the meeting. Each meeting should be
+published to YouTube.
+
+Items are added to the WG agenda that are considered contentious or
+are modifications of governance, contribution policy, WG membership,
+or release process.
+
+The intention of the agenda is not to approve or review all patches;
+that should happen continuously on GitHub and be handled by the larger
+group of Collaborators.
+
+Any community member or contributor can ask that something be added to
+the next meeting's agenda by logging a GitHub Issue. Any Collaborator,
+WG member or the moderator can add the item to the agenda by adding
+the ***WG-agenda*** tag to the issue.
+
+Prior to each WG meeting the moderator will share the Agenda with
+members of the WG. WG members can add any items they like to the
+agenda at the beginning of each meeting. The moderator and the WG
+cannot veto or remove items.
+
+The WG may invite persons or representatives from certain projects to
+participate in a non-voting capacity.
+
+The moderator is responsible for summarizing the discussion of each
+agenda item and sends it as a pull request after the meeting.
+
+### Consensus Seeking Process
+
+The WG follows a
+[Consensus
+Seeking](http://en.wikipedia.org/wiki/Consensus-seeking_decision-making)
+decision-making model.
+
+When an agenda item has appeared to reach a consensus the moderator
+will ask "Does anyone object?" as a final call for dissent from the
+consensus.
+
+If an agenda item cannot reach a consensus a WG member can call for
+either a closing vote or a vote to table the issue to the next
+meeting. The call for a vote must be seconded by a majority of the WG
+or else the discussion will continue. Simple majority wins.
+
+Note that changes to WG membership require a majority consensus. See
+"WG Membership" above.

+
+***Node-core streams for userland***
+
+This package is a mirror of the Streams2 and Streams3 implementations in
+Node-core.
+
+Full documentation may be found on the [Node.js website](https://nodejs.org/dist/v8.11.1/docs/api/stream.html).
+
+If you want to guarantee a stable streams base, regardless of what version of
+Node you, or the users of your libraries are using, use **readable-stream** *only* and avoid the *"stream"* module in Node-core, for background see [this blogpost](http://r.va.gg/2014/06/why-i-dont-use-nodes-core-stream-module.html).
+
+As of version 2.0.0 **readable-stream** uses semantic versioning.
+
+# Streams Working Group
+
+`readable-stream` is maintained by the Streams Working Group, which
+oversees the development and maintenance of the Streams API within
+Node.js. The responsibilities of the Streams Working Group include:
+
+* Addressing stream issues on the Node.js issue tracker.
+* Authoring and editing stream documentation within the Node.js project.
+* Reviewing changes to stream subclasses within the Node.js project.
+* Redirecting changes to streams from the Node.js project to this
+ project.
+* Assisting in the implementation of stream providers within Node.js.
+* Recommending versions of `readable-stream` to be included in Node.js.
+* Messaging about the future of streams to give the community advance
+ notice of changes.

+## Agenda
+
+Extracted from https://github.com/iojs/readable-stream/labels/wg-agenda prior to meeting.
+
+* adopt a charter [#105](https://github.com/iojs/readable-stream/issues/105)
+* release and versioning strategy [#101](https://github.com/iojs/readable-stream/issues/101)
+* simpler stream creation [#102](https://github.com/iojs/readable-stream/issues/102)
+* proposal: deprecate implicit flowing of streams [#99](https://github.com/iojs/readable-stream/issues/99)
+
+## Minutes
+
+### adopt a charter
+
+* group: +1's all around
+
+### What versioning scheme should be adopted?
+* group: +1’s 3.0.0
+* domenic+group: pulling in patches from other sources where appropriate
+* mikeal: version independently, suggesting versions for io.js
+* mikeal+domenic: work with TC to notify in advance of changes
+simpler stream creation
+
+### streamline creation of streams
+* sam: streamline creation of streams
+* domenic: nice simple solution posted
+ but, we lose the opportunity to change the model
+ may not be backwards incompatible (double check keys)
+
+ **action item:** domenic will check
+
+### remove implicit flowing of streams on(‘data’)
+* add isFlowing / isPaused
+* mikeal: worrying that we’re documenting polyfill methods – confuses users
+* domenic: more reflective API is probably good, with warning labels for users
+* new section for mad scientists (reflective stream access)
+* calvin: name the “third stateâ€
+* mikeal: maybe borrow the name from whatwg?
+* domenic: we’re missing the “third stateâ€
+* consensus: kind of difficult to name the third state
+* mikeal: figure out differences in states / compat
+* mathias: always flow on data – eliminates third state
+ * explore what it breaks
+
+**action items:**
+* ask isaac for ability to list packages by what public io.js APIs they use (esp. Stream)
+* ask rod/build for infrastructure
+* **chris**: explore the “flow on data†approach
+* add isPaused/isFlowing
+* add new docs section
+* move isPaused to that section
+

+
+// a transform stream is a readable/writable stream where you do
+// something with the data. Sometimes it's called a "filter",
+// but that's not a great name for it, since that implies a thing where
+// some bits pass through, and others are simply ignored. (That would
+// be a valid example of a transform, of course.)
+//
+// While the output is causally related to the input, it's not a
+// necessarily symmetric or synchronous transformation. For example,
+// a zlib stream might take multiple plain-text writes(), and then
+// emit a single compressed chunk some time in the future.
+//
+// Here's how this works:
+//
+// The Transform stream has all the aspects of the readable and writable
+// stream classes. When you write(chunk), that calls _write(chunk,cb)
+// internally, and returns false if there's a lot of pending writes
+// buffered up. When you call read(), that calls _read(n) until
+// there's enough pending readable data buffered up.
+//
+// In a transform stream, the written data is placed in a buffer. When
+// _read(n) is called, it transforms the queued up data, calling the
+// buffered _write cb's as it consumes chunks. If consuming a single
+// written chunk would result in multiple output chunks, then the first
+// outputted bit calls the readcb, and subsequent chunks just go into
+// the read buffer, and will cause it to emit 'readable' if necessary.
+//
+// This way, back-pressure is actually determined by the reading side,
+// since _read has to be called to start processing a new chunk. However,
+// a pathological inflate type of transform can cause excessive buffering
+// here. For example, imagine a stream where every byte of input is
+// interpreted as an integer from 0-255, and then results in that many
+// bytes of output. Writing the 4 bytes {ff,ff,ff,ff} would result in
+// 1kb of data being output. In this case, you could write a very small
+// amount of input, and end up with a very large amount of output. In
+// such a pathological inflating mechanism, there'd be no way to tell
+// the system to stop doing the transform. A single 4MB write could
+// cause the system to run out of memory.
+//
+// However, even in such a pathological case, only a single written chunk
+// would be consumed, and then the rest would wait (un-transformed) until
+// the results of the previous transformed chunk were consumed.

+#### Safer Node.js Buffer API
+
+**Use the new Node.js Buffer APIs (`Buffer.from`, `Buffer.alloc`,
+`Buffer.allocUnsafe`, `Buffer.allocUnsafeSlow`) in all versions of Node.js.**
+
+**Uses the built-in implementation when available.**
+
+## install
+
+```
+npm install safe-buffer
+```
+
+## usage
+
+The goal of this package is to provide a safe replacement for the node.js `Buffer`.
+
+It's a drop-in replacement for `Buffer`. You can use it by adding one `require` line to
+the top of your node.js modules:
+
+```js
+var Buffer = require('safe-buffer').Buffer
+
+// Existing buffer code will continue to work without issues:
+
+new Buffer('hey', 'utf8')
+new Buffer([1, 2, 3], 'utf8')
+new Buffer(obj)
+new Buffer(16) // create an uninitialized buffer (potentially unsafe)
+
+// But you can use these new explicit APIs to make clear what you want:
+
+Buffer.from('hey', 'utf8') // convert from many types to a Buffer
+Buffer.alloc(16) // create a zero-filled buffer (safe)
+Buffer.allocUnsafe(16) // create an uninitialized buffer (potentially unsafe)
+```
+
+## api
+
+### Class Method: Buffer.from(array)
+<!-- YAML
+added: v3.0.0
+-->
+
+* `array` {Array}
+
+Allocates a new `Buffer` using an `array` of octets.
+
+```js
+const buf = Buffer.from([0x62,0x75,0x66,0x66,0x65,0x72]);
+ // creates a new Buffer containing ASCII bytes
+ // ['b','u','f','f','e','r']
+```
+
+A `TypeError` will be thrown if `array` is not an `Array`.
+
+### Class Method: Buffer.from(arrayBuffer[, byteOffset[, length]])
+<!-- YAML
+added: v5.10.0
+-->
+
+* `arrayBuffer` {ArrayBuffer} The `.buffer` property of a `TypedArray` or
+ a `new ArrayBuffer()`
+* `byteOffset` {Number} Default: `0`
+* `length` {Number} Default: `arrayBuffer.length - byteOffset`
+
+When passed a reference to the `.buffer` property of a `TypedArray` instance,
+the newly created `Buffer` will share the same allocated memory as the
+TypedArray.
+
+```js
+const arr = new Uint16Array(2);
+arr[0] = 5000;
+arr[1] = 4000;
+
+const buf = Buffer.from(arr.buffer); // shares the memory with arr;
+
+console.log(buf);
+ // Prints: <Buffer 88 13 a0 0f>
+
+// changing the TypedArray changes the Buffer also
+arr[1] = 6000;
+
+console.log(buf);
+ // Prints: <Buffer 88 13 70 17>
+```
+
+The optional `byteOffset` and `length` arguments specify a memory range within
+the `arrayBuffer` that will be shared by the `Buffer`.
+
+```js
+const ab = new ArrayBuffer(10);
+const buf = Buffer.from(ab, 0, 2);
+console.log(buf.length);
+ // Prints: 2
+```
+
+A `TypeError` will be thrown if `arrayBuffer` is not an `ArrayBuffer`.
+
+### Class Method: Buffer.from(buffer)
+<!-- YAML
+added: v3.0.0
+-->
+
+* `buffer` {Buffer}
+
+Copies the passed `buffer` data onto a new `Buffer` instance.
+
+```js
+const buf1 = Buffer.from('buffer');
+const buf2 = Buffer.from(buf1);
+
+buf1[0] = 0x61;
+console.log(buf1.toString());
+ // 'auffer'
+console.log(buf2.toString());
+ // 'buffer' (copy is not changed)
+```
+
+A `TypeError` will be thrown if `buffer` is not a `Buffer`.
+
+### Class Method: Buffer.from(str[, encoding])
+<!-- YAML
+added: v5.10.0
+-->
+
+* `str` {String} String to encode.
+* `encoding` {String} Encoding to use, Default: `'utf8'`
+
+Creates a new `Buffer` containing the given JavaScript string `str`. If
+provided, the `encoding` parameter identifies the character encoding.
+If not provided, `encoding` defaults to `'utf8'`.
+
+```js
+const buf1 = Buffer.from('this is a tést');
+console.log(buf1.toString());
+ // prints: this is a tést
+console.log(buf1.toString('ascii'));
+ // prints: this is a tC)st
+
+const buf2 = Buffer.from('7468697320697320612074c3a97374', 'hex');
+console.log(buf2.toString());
+ // prints: this is a tést
+```
+
+A `TypeError` will be thrown if `str` is not a string.
+
+### Class Method: Buffer.alloc(size[, fill[, encoding]])
+<!-- YAML
+added: v5.10.0
+-->
+
+* `size` {Number}
+* `fill` {Value} Default: `undefined`
+* `encoding` {String} Default: `utf8`
+
+Allocates a new `Buffer` of `size` bytes. If `fill` is `undefined`, the
+`Buffer` will be *zero-filled*.
+
+```js
+const buf = Buffer.alloc(5);
+console.log(buf);
+ // <Buffer 00 00 00 00 00>
+```
+
+The `size` must be less than or equal to the value of
+`require('buffer').kMaxLength` (on 64-bit architectures, `kMaxLength` is
+`(2^31)-1`). Otherwise, a [`RangeError`][] is thrown. A zero-length Buffer will
+be created if a `size` less than or equal to 0 is specified.
+
+If `fill` is specified, the allocated `Buffer` will be initialized by calling
+`buf.fill(fill)`. See [`buf.fill()`][] for more information.
+
+```js
+const buf = Buffer.alloc(5, 'a');
+console.log(buf);
+ // <Buffer 61 61 61 61 61>
+```
+
+If both `fill` and `encoding` are specified, the allocated `Buffer` will be
+initialized by calling `buf.fill(fill, encoding)`. For example:
+
+```js
+const buf = Buffer.alloc(11, 'aGVsbG8gd29ybGQ=', 'base64');
+console.log(buf);
+ // <Buffer 68 65 6c 6c 6f 20 77 6f 72 6c 64>
+```
+
+Calling `Buffer.alloc(size)` can be significantly slower than the alternative
+`Buffer.allocUnsafe(size)` but ensures that the newly created `Buffer` instance
+contents will *never contain sensitive data*.
+
+A `TypeError` will be thrown if `size` is not a number.
+
+### Class Method: Buffer.allocUnsafe(size)
+<!-- YAML
+added: v5.10.0
+-->
+
+* `size` {Number}
+
+Allocates a new *non-zero-filled* `Buffer` of `size` bytes. The `size` must
+be less than or equal to the value of `require('buffer').kMaxLength` (on 64-bit
+architectures, `kMaxLength` is `(2^31)-1`). Otherwise, a [`RangeError`][] is
+thrown. A zero-length Buffer will be created if a `size` less than or equal to
+0 is specified.
+
+The underlying memory for `Buffer` instances created in this way is *not
+initialized*. The contents of the newly created `Buffer` are unknown and
+*may contain sensitive data*. Use [`buf.fill(0)`][] to initialize such
+`Buffer` instances to zeroes.
+
+```js
+const buf = Buffer.allocUnsafe(5);
+console.log(buf);
+ // <Buffer 78 e0 82 02 01>
+ // (octets will be different, every time)
+buf.fill(0);
+console.log(buf);
+ // <Buffer 00 00 00 00 00>
+```
+
+A `TypeError` will be thrown if `size` is not a number.
+
+Note that the `Buffer` module pre-allocates an internal `Buffer` instance of
+size `Buffer.poolSize` that is used as a pool for the fast allocation of new
+`Buffer` instances created using `Buffer.allocUnsafe(size)` (and the deprecated
+`new Buffer(size)` constructor) only when `size` is less than or equal to
+`Buffer.poolSize >> 1` (floor of `Buffer.poolSize` divided by two). The default
+value of `Buffer.poolSize` is `8192` but can be modified.
+
+Use of this pre-allocated internal memory pool is a key difference between
+calling `Buffer.alloc(size, fill)` vs. `Buffer.allocUnsafe(size).fill(fill)`.
+Specifically, `Buffer.alloc(size, fill)` will *never* use the internal Buffer
+pool, while `Buffer.allocUnsafe(size).fill(fill)` *will* use the internal
+Buffer pool if `size` is less than or equal to half `Buffer.poolSize`. The
+difference is subtle but can be important when an application requires the
+additional performance that `Buffer.allocUnsafe(size)` provides.
+
+### Class Method: Buffer.allocUnsafeSlow(size)
+<!-- YAML
+added: v5.10.0
+-->
+
+* `size` {Number}
+
+Allocates a new *non-zero-filled* and non-pooled `Buffer` of `size` bytes. The
+`size` must be less than or equal to the value of
+`require('buffer').kMaxLength` (on 64-bit architectures, `kMaxLength` is
+`(2^31)-1`). Otherwise, a [`RangeError`][] is thrown. A zero-length Buffer will
+be created if a `size` less than or equal to 0 is specified.
+
+The underlying memory for `Buffer` instances created in this way is *not
+initialized*. The contents of the newly created `Buffer` are unknown and
+*may contain sensitive data*. Use [`buf.fill(0)`][] to initialize such
+`Buffer` instances to zeroes.
+
+When using `Buffer.allocUnsafe()` to allocate new `Buffer` instances,
+allocations under 4KB are, by default, sliced from a single pre-allocated
+`Buffer`. This allows applications to avoid the garbage collection overhead of
+creating many individually allocated Buffers. This approach improves both
+performance and memory usage by eliminating the need to track and cleanup as
+many `Persistent` objects.
+
+However, in the case where a developer may need to retain a small chunk of
+memory from a pool for an indeterminate amount of time, it may be appropriate
+to create an un-pooled Buffer instance using `Buffer.allocUnsafeSlow()` then
+copy out the relevant bits.
+
+```js
+// need to keep around a few small chunks of memory
+const store = [];
+
+socket.on('readable', () => {
+ const data = socket.read();
+ // allocate for retained data
+ const sb = Buffer.allocUnsafeSlow(10);
+ // copy the data into the new allocation
+ data.copy(sb, 0, 0, 10);
+ store.push(sb);
+});
+```
+
+Use of `Buffer.allocUnsafeSlow()` should be used only as a last resort *after*
+a developer has observed undue memory retention in their applications.
+
+A `TypeError` will be thrown if `size` is not a number.
+
+### All the Rest
+
+The rest of the `Buffer` API is exactly the same as in node.js.
+[See the docs](https://nodejs.org/api/buffer.html).
+
+
+## Related links
+
+- [Node.js issue: Buffer(number) is unsafe](https://github.com/nodejs/node/issues/4660)
+- [Node.js Enhancement Proposal: Buffer.from/Buffer.alloc/Buffer.zalloc/Buffer() soft-deprecate](https://github.com/nodejs/node-eps/pull/4)
+
+## Why is `Buffer` unsafe?
+
+Today, the node.js `Buffer` constructor is overloaded to handle many different argument
+types like `String`, `Array`, `Object`, `TypedArrayView` (`Uint8Array`, etc.),
+`ArrayBuffer`, and also `Number`.
+
+The API is optimized for convenience: you can throw any type at it, and it will try to do
+what you want.
+
+Because the Buffer constructor is so powerful, you often see code like this:
+
+```js
+// Convert UTF-8 strings to hex
+function toHex (str) {
+ return new Buffer(str).toString('hex')
+}
+```
+
+***But what happens if `toHex` is called with a `Number` argument?***
+
+### Remote Memory Disclosure
+
+If an attacker can make your program call the `Buffer` constructor with a `Number`
+argument, then they can make it allocate uninitialized memory from the node.js process.
+This could potentially disclose TLS private keys, user data, or database passwords.
+
+When the `Buffer` constructor is passed a `Number` argument, it returns an
+**UNINITIALIZED** block of memory of the specified `size`. When you create a `Buffer` like
+this, you **MUST** overwrite the contents before returning it to the user.
+
+From the [node.js docs](https://nodejs.org/api/buffer.html#buffer_new_buffer_size):
+
+> `new Buffer(size)`
+>
+> - `size` Number
+>
+> The underlying memory for `Buffer` instances created in this way is not initialized.
+> **The contents of a newly created `Buffer` are unknown and could contain sensitive
+> data.** Use `buf.fill(0)` to initialize a Buffer to zeroes.
+
+(Emphasis our own.)
+
+Whenever the programmer intended to create an uninitialized `Buffer` you often see code
+like this:
+
+```js
+var buf = new Buffer(16)
+
+// Immediately overwrite the uninitialized buffer with data from another buffer
+for (var i = 0; i < buf.length; i++) {
+ buf[i] = otherBuf[i]
+}
+```
+
+
+### Would this ever be a problem in real code?
+
+Yes. It's surprisingly common to forget to check the type of your variables in a
+dynamically-typed language like JavaScript.
+
+Usually the consequences of assuming the wrong type is that your program crashes with an
+uncaught exception. But the failure mode for forgetting to check the type of arguments to
+the `Buffer` constructor is more catastrophic.
+
+Here's an example of a vulnerable service that takes a JSON payload and converts it to
+hex:
+
+```js
+// Take a JSON payload {str: "some string"} and convert it to hex
+var server = http.createServer(function (req, res) {
+ var data = ''
+ req.setEncoding('utf8')
+ req.on('data', function (chunk) {
+ data += chunk
+ })
+ req.on('end', function () {
+ var body = JSON.parse(data)
+ res.end(new Buffer(body.str).toString('hex'))
+ })
+})
+
+server.listen(8080)
+```
+
+In this example, an http client just has to send:
+
+```json
+{
+ "str": 1000
+}
+```
+
+and it will get back 1,000 bytes of uninitialized memory from the server.
+
+This is a very serious bug. It's similar in severity to the
+[the Heartbleed bug](http://heartbleed.com/) that allowed disclosure of OpenSSL process
+memory by remote attackers.
+
+
+### Which real-world packages were vulnerable?
+
+#### [`bittorrent-dht`](https://www.npmjs.com/package/bittorrent-dht)
+
+[Mathias Buus](https://github.com/mafintosh) and I
+([Feross Aboukhadijeh](http://feross.org/)) found this issue in one of our own packages,
+[`bittorrent-dht`](https://www.npmjs.com/package/bittorrent-dht). The bug would allow
+anyone on the internet to send a series of messages to a user of `bittorrent-dht` and get
+them to reveal 20 bytes at a time of uninitialized memory from the node.js process.
+
+Here's
+[the commit](https://github.com/feross/bittorrent-dht/commit/6c7da04025d5633699800a99ec3fbadf70ad35b8)
+that fixed it. We released a new fixed version, created a
+[Node Security Project disclosure](https://nodesecurity.io/advisories/68), and deprecated all
+vulnerable versions on npm so users will get a warning to upgrade to a newer version.
+
+#### [`ws`](https://www.npmjs.com/package/ws)
+
+That got us wondering if there were other vulnerable packages. Sure enough, within a short
+period of time, we found the same issue in [`ws`](https://www.npmjs.com/package/ws), the
+most popular WebSocket implementation in node.js.
+
+If certain APIs were called with `Number` parameters instead of `String` or `Buffer` as
+expected, then uninitialized server memory would be disclosed to the remote peer.
+
+These were the vulnerable methods:
+
+```js
+socket.send(number)
+socket.ping(number)
+socket.pong(number)
+```
+
+Here's a vulnerable socket server with some echo functionality:
+
+```js
+server.on('connection', function (socket) {
+ socket.on('message', function (message) {
+ message = JSON.parse(message)
+ if (message.type === 'echo') {
+ socket.send(message.data) // send back the user's message
+ }
+ })
+})
+```
+
+`socket.send(number)` called on the server, will disclose server memory.
+
+Here's [the release](https://github.com/websockets/ws/releases/tag/1.0.1) where the issue
+was fixed, with a more detailed explanation. Props to
+[Arnout Kazemier](https://github.com/3rd-Eden) for the quick fix. Here's the
+[Node Security Project disclosure](https://nodesecurity.io/advisories/67).
+
+
+### What's the solution?
+
+It's important that node.js offers a fast way to get memory otherwise performance-critical
+applications would needlessly get a lot slower.
+
+But we need a better way to *signal our intent* as programmers. **When we want
+uninitialized memory, we should request it explicitly.**
+
+Sensitive functionality should not be packed into a developer-friendly API that loosely
+accepts many different types. This type of API encourages the lazy practice of passing
+variables in without checking the type very carefully.
+
+#### A new API: `Buffer.allocUnsafe(number)`
+
+The functionality of creating buffers with uninitialized memory should be part of another
+API. We propose `Buffer.allocUnsafe(number)`. This way, it's not part of an API that
+frequently gets user input of all sorts of different types passed into it.
+
+```js
+var buf = Buffer.allocUnsafe(16) // careful, uninitialized memory!
+
+// Immediately overwrite the uninitialized buffer with data from another buffer
+for (var i = 0; i < buf.length; i++) {
+ buf[i] = otherBuf[i]
+}
+```
+
+
+### How do we fix node.js core?
+
+We sent [a PR to node.js core](https://github.com/nodejs/node/pull/4514) (merged as
+`semver-major`) which defends against one case:
+
+```js
+var str = 16
+new Buffer(str, 'utf8')
+```
+
+In this situation, it's implied that the programmer intended the first argument to be a
+string, since they passed an encoding as a second argument. Today, node.js will allocate
+uninitialized memory in the case of `new Buffer(number, encoding)`, which is probably not
+what the programmer intended.
+
+But this is only a partial solution, since if the programmer does `new Buffer(variable)`
+(without an `encoding` parameter) there's no way to know what they intended. If `variable`
+is sometimes a number, then uninitialized memory will sometimes be returned.
+
+### What's the real long-term fix?
+
+We could deprecate and remove `new Buffer(number)` and use `Buffer.allocUnsafe(number)` when
+we need uninitialized memory. But that would break 1000s of packages.
+
+~~We believe the best solution is to:~~
+
+~~1. Change `new Buffer(number)` to return safe, zeroed-out memory~~
+
+~~2. Create a new API for creating uninitialized Buffers. We propose: `Buffer.allocUnsafe(number)`~~
+
+#### Update
+
+We now support adding three new APIs:
+
+- `Buffer.from(value)` - convert from any type to a buffer
+- `Buffer.alloc(size)` - create a zero-filled buffer
+- `Buffer.allocUnsafe(size)` - create an uninitialized buffer with given size
+
+This solves the core problem that affected `ws` and `bittorrent-dht` which is
+`Buffer(variable)` getting tricked into taking a number argument.
+
+This way, existing code continues working and the impact on the npm ecosystem will be
+minimal. Over time, npm maintainers can migrate performance-critical code to use
+`Buffer.allocUnsafe(number)` instead of `new Buffer(number)`.
+
+
+### Conclusion
+
+We think there's a serious design issue with the `Buffer` API as it exists today. It
+promotes insecure software by putting high-risk functionality into a convenient API
+with friendly "developer ergonomics".
+
+This wasn't merely a theoretical exercise because we found the issue in some of the
+most popular npm packages.
+
+Fortunately, there's an easy fix that can be applied today. Use `safe-buffer` in place of
+`buffer`.
+
+```js
+var Buffer = require('safe-buffer').Buffer
+```
+
+Eventually, we hope that node.js core can switch to this new, safer behavior. We believe
+the impact on the ecosystem would be minimal since it's not a breaking change.
+Well-maintained, popular packages would be updated to use `Buffer.alloc` quickly, while
+older, insecure packages would magically become safe from this attack vector.

+semver(1) -- The semantic versioner for npm
+===========================================
+
+## Install
+
+```bash
+npm install --save semver
+````
+
+## Usage
+
+As a node module:
+
+```js
+const semver = require('semver')
+
+semver.valid('1.2.3') // '1.2.3'
+semver.valid('a.b.c') // null
+semver.clean(' =v1.2.3 ') // '1.2.3'
+semver.satisfies('1.2.3', '1.x || >=2.5.0 || 5.0.0 - 7.2.3') // true
+semver.gt('1.2.3', '9.8.7') // false
+semver.lt('1.2.3', '9.8.7') // true
+semver.minVersion('>=1.0.0') // '1.0.0'
+semver.valid(semver.coerce('v2')) // '2.0.0'
+semver.valid(semver.coerce('42.6.7.9.3-alpha')) // '42.6.7'
+```
+
+As a command-line utility:
+
+```
+$ semver -h
+
+A JavaScript implementation of the https://semver.org/ specification
+Copyright Isaac Z. Schlueter
+
+Usage: semver [options] <version> [<version> [...]]
+Prints valid versions sorted by SemVer precedence
+
+Options:
+-r --range <range>
+ Print versions that match the specified range.
+
+-i --increment [<level>]
+ Increment a version by the specified level. Level can
+ be one of: major, minor, patch, premajor, preminor,
+ prepatch, or prerelease. Default level is 'patch'.
+ Only one version may be specified.
+
+--preid <identifier>
+ Identifier to be used to prefix premajor, preminor,
+ prepatch or prerelease version increments.
+
+-l --loose
+ Interpret versions and ranges loosely
+
+-p --include-prerelease
+ Always include prerelease versions in range matching
+
+-c --coerce
+ Coerce a string into SemVer if possible
+ (does not imply --loose)
+
+Program exits successfully if any valid version satisfies
+all supplied ranges, and prints all satisfying versions.
+
+If no satisfying versions are found, then exits failure.
+
+Versions are printed in ascending order, so supplying
+multiple versions to the utility will just sort them.
+```
+
+## Versions
+
+A "version" is described by the `v2.0.0` specification found at
+<https://semver.org/>.
+
+A leading `"="` or `"v"` character is stripped off and ignored.
+
+## Ranges
+
+A `version range` is a set of `comparators` which specify versions
+that satisfy the range.
+
+A `comparator` is composed of an `operator` and a `version`. The set
+of primitive `operators` is:
+
+* `<` Less than
+* `<=` Less than or equal to
+* `>` Greater than
+* `>=` Greater than or equal to
+* `=` Equal. If no operator is specified, then equality is assumed,
+ so this operator is optional, but MAY be included.
+
+For example, the comparator `>=1.2.7` would match the versions
+`1.2.7`, `1.2.8`, `2.5.3`, and `1.3.9`, but not the versions `1.2.6`
+or `1.1.0`.
+
+Comparators can be joined by whitespace to form a `comparator set`,
+which is satisfied by the **intersection** of all of the comparators
+it includes.
+
+A range is composed of one or more comparator sets, joined by `||`. A
+version matches a range if and only if every comparator in at least
+one of the `||`-separated comparator sets is satisfied by the version.
+
+For example, the range `>=1.2.7 <1.3.0` would match the versions
+`1.2.7`, `1.2.8`, and `1.2.99`, but not the versions `1.2.6`, `1.3.0`,
+or `1.1.0`.
+
+The range `1.2.7 || >=1.2.9 <2.0.0` would match the versions `1.2.7`,
+`1.2.9`, and `1.4.6`, but not the versions `1.2.8` or `2.0.0`.
+
+### Prerelease Tags
+
+If a version has a prerelease tag (for example, `1.2.3-alpha.3`) then
+it will only be allowed to satisfy comparator sets if at least one
+comparator with the same `[major, minor, patch]` tuple also has a
+prerelease tag.
+
+For example, the range `>1.2.3-alpha.3` would be allowed to match the
+version `1.2.3-alpha.7`, but it would *not* be satisfied by
+`3.4.5-alpha.9`, even though `3.4.5-alpha.9` is technically "greater
+than" `1.2.3-alpha.3` according to the SemVer sort rules. The version
+range only accepts prerelease tags on the `1.2.3` version. The
+version `3.4.5` *would* satisfy the range, because it does not have a
+prerelease flag, and `3.4.5` is greater than `1.2.3-alpha.7`.
+
+The purpose for this behavior is twofold. First, prerelease versions
+frequently are updated very quickly, and contain many breaking changes
+that are (by the author's design) not yet fit for public consumption.
+Therefore, by default, they are excluded from range matching
+semantics.
+
+Second, a user who has opted into using a prerelease version has
+clearly indicated the intent to use *that specific* set of
+alpha/beta/rc versions. By including a prerelease tag in the range,
+the user is indicating that they are aware of the risk. However, it
+is still not appropriate to assume that they have opted into taking a
+similar risk on the *next* set of prerelease versions.
+
+Note that this behavior can be suppressed (treating all prerelease
+versions as if they were normal versions, for the purpose of range
+matching) by setting the `includePrerelease` flag on the options
+object to any
+[functions](https://github.com/npm/node-semver#functions) that do
+range matching.
+
+#### Prerelease Identifiers
+
+The method `.inc` takes an additional `identifier` string argument that
+will append the value of the string as a prerelease identifier:
+
+```javascript
+semver.inc('1.2.3', 'prerelease', 'beta')
+// '1.2.4-beta.0'
+```
+
+command-line example:
+
+```bash
+$ semver 1.2.3 -i prerelease --preid beta
+1.2.4-beta.0
+```
+
+Which then can be used to increment further:
+
+```bash
+$ semver 1.2.4-beta.0 -i prerelease
+1.2.4-beta.1
+```
+
+### Advanced Range Syntax
+
+Advanced range syntax desugars to primitive comparators in
+deterministic ways.
+
+Advanced ranges may be combined in the same way as primitive
+comparators using white space or `||`.
+
+#### Hyphen Ranges `X.Y.Z - A.B.C`
+
+Specifies an inclusive set.
+
+* `1.2.3 - 2.3.4` := `>=1.2.3 <=2.3.4`
+
+If a partial version is provided as the first version in the inclusive
+range, then the missing pieces are replaced with zeroes.
+
+* `1.2 - 2.3.4` := `>=1.2.0 <=2.3.4`
+
+If a partial version is provided as the second version in the
+inclusive range, then all versions that start with the supplied parts
+of the tuple are accepted, but nothing that would be greater than the
+provided tuple parts.
+
+* `1.2.3 - 2.3` := `>=1.2.3 <2.4.0`
+* `1.2.3 - 2` := `>=1.2.3 <3.0.0`
+
+#### X-Ranges `1.2.x` `1.X` `1.2.*` `*`
+
+Any of `X`, `x`, or `*` may be used to "stand in" for one of the
+numeric values in the `[major, minor, patch]` tuple.
+
+* `*` := `>=0.0.0` (Any version satisfies)
+* `1.x` := `>=1.0.0 <2.0.0` (Matching major version)
+* `1.2.x` := `>=1.2.0 <1.3.0` (Matching major and minor versions)
+
+A partial version range is treated as an X-Range, so the special
+character is in fact optional.
+
+* `""` (empty string) := `*` := `>=0.0.0`
+* `1` := `1.x.x` := `>=1.0.0 <2.0.0`
+* `1.2` := `1.2.x` := `>=1.2.0 <1.3.0`
+
+#### Tilde Ranges `~1.2.3` `~1.2` `~1`
+
+Allows patch-level changes if a minor version is specified on the
+comparator. Allows minor-level changes if not.
+
+* `~1.2.3` := `>=1.2.3 <1.(2+1).0` := `>=1.2.3 <1.3.0`
+* `~1.2` := `>=1.2.0 <1.(2+1).0` := `>=1.2.0 <1.3.0` (Same as `1.2.x`)
+* `~1` := `>=1.0.0 <(1+1).0.0` := `>=1.0.0 <2.0.0` (Same as `1.x`)
+* `~0.2.3` := `>=0.2.3 <0.(2+1).0` := `>=0.2.3 <0.3.0`
+* `~0.2` := `>=0.2.0 <0.(2+1).0` := `>=0.2.0 <0.3.0` (Same as `0.2.x`)
+* `~0` := `>=0.0.0 <(0+1).0.0` := `>=0.0.0 <1.0.0` (Same as `0.x`)
+* `~1.2.3-beta.2` := `>=1.2.3-beta.2 <1.3.0` Note that prereleases in
+ the `1.2.3` version will be allowed, if they are greater than or
+ equal to `beta.2`. So, `1.2.3-beta.4` would be allowed, but
+ `1.2.4-beta.2` would not, because it is a prerelease of a
+ different `[major, minor, patch]` tuple.
+
+#### Caret Ranges `^1.2.3` `^0.2.5` `^0.0.4`
+
+Allows changes that do not modify the left-most non-zero digit in the
+`[major, minor, patch]` tuple. In other words, this allows patch and
+minor updates for versions `1.0.0` and above, patch updates for
+versions `0.X >=0.1.0`, and *no* updates for versions `0.0.X`.
+
+Many authors treat a `0.x` version as if the `x` were the major
+"breaking-change" indicator.
+
+Caret ranges are ideal when an author may make breaking changes
+between `0.2.4` and `0.3.0` releases, which is a common practice.
+However, it presumes that there will *not* be breaking changes between
+`0.2.4` and `0.2.5`. It allows for changes that are presumed to be
+additive (but non-breaking), according to commonly observed practices.
+
+* `^1.2.3` := `>=1.2.3 <2.0.0`
+* `^0.2.3` := `>=0.2.3 <0.3.0`
+* `^0.0.3` := `>=0.0.3 <0.0.4`
+* `^1.2.3-beta.2` := `>=1.2.3-beta.2 <2.0.0` Note that prereleases in
+ the `1.2.3` version will be allowed, if they are greater than or
+ equal to `beta.2`. So, `1.2.3-beta.4` would be allowed, but
+ `1.2.4-beta.2` would not, because it is a prerelease of a
+ different `[major, minor, patch]` tuple.
+* `^0.0.3-beta` := `>=0.0.3-beta <0.0.4` Note that prereleases in the
+ `0.0.3` version *only* will be allowed, if they are greater than or
+ equal to `beta`. So, `0.0.3-pr.2` would be allowed.
+
+When parsing caret ranges, a missing `patch` value desugars to the
+number `0`, but will allow flexibility within that value, even if the
+major and minor versions are both `0`.
+
+* `^1.2.x` := `>=1.2.0 <2.0.0`
+* `^0.0.x` := `>=0.0.0 <0.1.0`
+* `^0.0` := `>=0.0.0 <0.1.0`
+
+A missing `minor` and `patch` values will desugar to zero, but also
+allow flexibility within those values, even if the major version is
+zero.
+
+* `^1.x` := `>=1.0.0 <2.0.0`
+* `^0.x` := `>=0.0.0 <1.0.0`
+
+### Range Grammar
+
+Putting all this together, here is a Backus-Naur grammar for ranges,
+for the benefit of parser authors:
+
+```bnf
+range-set ::= range ( logical-or range ) *
+logical-or ::= ( ' ' ) * '||' ( ' ' ) *
+range ::= hyphen | simple ( ' ' simple ) * | ''
+hyphen ::= partial ' - ' partial
+simple ::= primitive | partial | tilde | caret
+primitive ::= ( '<' | '>' | '>=' | '<=' | '=' ) partial
+partial ::= xr ( '.' xr ( '.' xr qualifier ? )? )?
+xr ::= 'x' | 'X' | '*' | nr
+nr ::= '0' | ['1'-'9'] ( ['0'-'9'] ) *
+tilde ::= '~' partial
+caret ::= '^' partial
+qualifier ::= ( '-' pre )? ( '+' build )?
+pre ::= parts
+build ::= parts
+parts ::= part ( '.' part ) *
+part ::= nr | [-0-9A-Za-z]+
+```
+
+## Functions
+
+All methods and classes take a final `options` object argument. All
+options in this object are `false` by default. The options supported
+are:
+
+- `loose` Be more forgiving about not-quite-valid semver strings.
+ (Any resulting output will always be 100% strict compliant, of
+ course.) For backwards compatibility reasons, if the `options`
+ argument is a boolean value instead of an object, it is interpreted
+ to be the `loose` param.
+- `includePrerelease` Set to suppress the [default
+ behavior](https://github.com/npm/node-semver#prerelease-tags) of
+ excluding prerelease tagged versions from ranges unless they are
+ explicitly opted into.
+
+Strict-mode Comparators and Ranges will be strict about the SemVer
+strings that they parse.
+
+* `valid(v)`: Return the parsed version, or null if it's not valid.
+* `inc(v, release)`: Return the version incremented by the release
+ type (`major`, `premajor`, `minor`, `preminor`, `patch`,
+ `prepatch`, or `prerelease`), or null if it's not valid
+ * `premajor` in one call will bump the version up to the next major
+ version and down to a prerelease of that major version.
+ `preminor`, and `prepatch` work the same way.
+ * If called from a non-prerelease version, the `prerelease` will work the
+ same as `prepatch`. It increments the patch version, then makes a
+ prerelease. If the input version is already a prerelease it simply
+ increments it.
+* `prerelease(v)`: Returns an array of prerelease components, or null
+ if none exist. Example: `prerelease('1.2.3-alpha.1') -> ['alpha', 1]`
+* `major(v)`: Return the major version number.
+* `minor(v)`: Return the minor version number.
+* `patch(v)`: Return the patch version number.
+* `intersects(r1, r2, loose)`: Return true if the two supplied ranges
+ or comparators intersect.
+* `parse(v)`: Attempt to parse a string as a semantic version, returning either
+ a `SemVer` object or `null`.
+
+### Comparison
+
+* `gt(v1, v2)`: `v1 > v2`
+* `gte(v1, v2)`: `v1 >= v2`
+* `lt(v1, v2)`: `v1 < v2`
+* `lte(v1, v2)`: `v1 <= v2`
+* `eq(v1, v2)`: `v1 == v2` This is true if they're logically equivalent,
+ even if they're not the exact same string. You already know how to
+ compare strings.
+* `neq(v1, v2)`: `v1 != v2` The opposite of `eq`.
+* `cmp(v1, comparator, v2)`: Pass in a comparison string, and it'll call
+ the corresponding function above. `"==="` and `"!=="` do simple
+ string comparison, but are included for completeness. Throws if an
+ invalid comparison string is provided.
+* `compare(v1, v2)`: Return `0` if `v1 == v2`, or `1` if `v1` is greater, or `-1` if
+ `v2` is greater. Sorts in ascending order if passed to `Array.sort()`.
+* `rcompare(v1, v2)`: The reverse of compare. Sorts an array of versions
+ in descending order when passed to `Array.sort()`.
+* `diff(v1, v2)`: Returns difference between two versions by the release type
+ (`major`, `premajor`, `minor`, `preminor`, `patch`, `prepatch`, or `prerelease`),
+ or null if the versions are the same.
+
+### Comparators
+
+* `intersects(comparator)`: Return true if the comparators intersect
+
+### Ranges
+
+* `validRange(range)`: Return the valid range or null if it's not valid
+* `satisfies(version, range)`: Return true if the version satisfies the
+ range.
+* `maxSatisfying(versions, range)`: Return the highest version in the list
+ that satisfies the range, or `null` if none of them do.
+* `minSatisfying(versions, range)`: Return the lowest version in the list
+ that satisfies the range, or `null` if none of them do.
+* `minVersion(range)`: Return the lowest version that can possibly match
+ the given range.
+* `gtr(version, range)`: Return `true` if version is greater than all the
+ versions possible in the range.
+* `ltr(version, range)`: Return `true` if version is less than all the
+ versions possible in the range.
+* `outside(version, range, hilo)`: Return true if the version is outside
+ the bounds of the range in either the high or low direction. The
+ `hilo` argument must be either the string `'>'` or `'<'`. (This is
+ the function called by `gtr` and `ltr`.)
+* `intersects(range)`: Return true if any of the ranges comparators intersect
+
+Note that, since ranges may be non-contiguous, a version might not be
+greater than a range, less than a range, *or* satisfy a range! For
+example, the range `1.2 <1.2.9 || >2.0.0` would have a hole from `1.2.9`
+until `2.0.0`, so the version `1.2.10` would not be greater than the
+range (because `2.0.1` satisfies, which is higher), nor less than the
+range (since `1.2.8` satisfies, which is lower), and it also does not
+satisfy the range.
+
+If you want to know if a version satisfies or does not satisfy a
+range, use the `satisfies(version, range)` function.
+
+### Coercion
+
+* `coerce(version)`: Coerces a string to semver if possible
+
+This aims to provide a very forgiving translation of a non-semver string to
+semver. It looks for the first digit in a string, and consumes all
+remaining characters which satisfy at least a partial semver (e.g., `1`,
+`1.2`, `1.2.3`) up to the max permitted length (256 characters). Longer
+versions are simply truncated (`4.6.3.9.2-alpha2` becomes `4.6.3`). All
+surrounding text is simply ignored (`v3.4 replaces v3.3.1` becomes
+`3.4.0`). Only text which lacks digits will fail coercion (`version one`
+is not valid). The maximum length for any semver component considered for
+coercion is 16 characters; longer components will be ignored
+(`10000000000000000.4.7.4` becomes `4.7.4`). The maximum value for any
+semver component is `Number.MAX_SAFE_INTEGER || (2**53 - 1)`; higher value
+components are invalid (`9999999999999999.4.7.4` is likely invalid).

+# SerialPort
+
+Access serial ports with JavaScript. Linux, OSX and Windows. Welcome your robotic JavaScript overlords. Better yet, program them!
+
+> Go to https://serialport.io/ to learn more, find guides and api documentation.
+
+## Quick Links
+- [**Guides**](https://serialport.io/docs/guide-about)
+- [**API Docs**](https://serialport.io/docs/api-serialport)
+- [The `serialport` package api docs](https://serialport.io/docs/api-serialport)
+
+
+### Serialport
+- [`serialport`](https://serialport.io/docs/api-serialport) Chances are you're looking for the `serialport` package which provides a good set of defaults for most projects. However it is quite easy to mix and match the parts of serialport you need.
+
+### Bindings
+The Bindings provide a low level interface to work with your serialport. It is possible to use them alone but it's usually easier to use them with an interface.
+- [`@serialport/bindings`](https://serialport.io/docs/api-bindings) bindings for Linux, Mac and Windows
+- [`@serialport/binding-abstract`](https://serialport.io/docs/api-bindings-abstract) as an abstract class to use if you're making your own bindings
+- [`@serialport/binding-mock`](https://serialport.io/docs/api-binding-mock) for a mock binding package for testing
+
+### Interfaces
+Interfaces take a binding object and provide a different API on top of it. Currently we only ship a Node Stream Interface.
+
+- [`@serialport/stream`](https://serialport.io/docs/api-stream) our traditional Node.js Stream interface
+
+### Parsers
+
+Parsers are used to take raw binary data and transform them into usable messages. This may include tasks such as converting the data to text, emitting useful chunks of data when they have been fully received, or even validating protocols.
+
+Parsers are traditionally Transform streams, but Duplex streams and other non stream interfaces are acceptable.

+
+## Developing
+
+### Developing node serialport projects
+1. Clone this repo `git clone git@github.com:serialport/node-serialport.git`
+1. Run `npm install` to setup local package dependencies (run this any time you depend on a package local to this repo)
+1. Run `npm test` to ensure everything is working properly
+1. Run `npm run generate` to generate a new project
+1. Add dev dependencies to the root package.json and package dependencies to the package's one.
+
+### Developing Docs
+
+You can develop the docs by running
+
+```bash
+npm run docs:dev
+```
+
+And build them by running
+```bash
+npm run docs
+```
+
+Docs are automatically built with [netlify](https://www.netlify.com/pricing/) including previews on branches. The master branch is deployed to https://serialport.io
+
+## License
+SerialPort packages are all [MIT licensed](LICENSE) and all it's dependencies are MIT licensed.
+
+## Code of Conduct
+SerialPort follows the [Nodebots Code of Conduct](http://nodebots.io/conduct.html). While the code is MIT licensed participation in the community has some rules to make this a good place to work and learn.

+# set-blocking
+
+[](https://travis-ci.org/yargs/set-blocking)
+[](https://www.npmjs.com/package/set-blocking)
+[](https://coveralls.io/r/yargs/set-blocking?branch=master)
+[](https://github.com/conventional-changelog/standard-version)
+
+set blocking `stdio` and `stderr` ensuring that terminal output does not truncate.
+
+```js
+const setBlocking = require('set-blocking')
+setBlocking(true)
+console.log(someLargeStringToOutput)
+```
+
+## Historical Context/Word of Warning
+
+This was created as a shim to address the bug discussed in [node #6456](https://github.com/nodejs/node/issues/6456). This bug crops up on
+newer versions of Node.js (`0.12+`), truncating terminal output.
+
+You should be mindful of the side-effects caused by using `set-blocking`:
+
+* if your module sets blocking to `true`, it will effect other modules
+ consuming your library. In [yargs](https://github.com/yargs/yargs/blob/master/yargs.js#L653) we only call
+ `setBlocking(true)` once we already know we are about to call `process.exit(code)`.
+* this patch will not apply to subprocesses spawned with `isTTY = true`, this is
+ the [default `spawn()` behavior](https://nodejs.org/api/child_process.html#child_process_child_process_spawn_command_args_options).

+# signal-exit
+
+[](https://travis-ci.org/tapjs/signal-exit)

+[](https://www.npmjs.com/package/signal-exit)
+[](https://github.com/conventional-changelog/standard-version)
+
+When you want to fire an event no matter how a process exits:
+
+* reaching the end of execution.
+* explicitly having `process.exit(code)` called.
+* having `process.kill(pid, sig)` called.
+* receiving a fatal signal from outside the process
+
+Use `signal-exit`.
+
+```js
+var onExit = require('signal-exit')
+
+onExit(function (code, signal) {
+ console.log('process exited!')
+})
+```
+
+## API
+
+`var remove = onExit(function (code, signal) {}, options)`
+
+The return value of the function is a function that will remove the
+handler.
+
+Note that the function *only* fires for signals if the signal would
+cause the proces to exit. That is, there are no other listeners, and
+it is a fatal signal.
+
+## Options
+
+* `alwaysLast`: Run this handler after any other signal or exit
+ handlers. This causes `process.emit` to be monkeypatched.

+### Simplest way to make http get requests
+
+## features
+
+This module is the lightest possible wrapper on top of node.js `http`, but supporting these essential features:
+
+- follows redirects
+- automatically handles gzip/deflate responses
+- supports HTTPS
+- supports specifying a timeout
+- supports convenience `url` key so there's no need to use `url.parse` on the url when specifying options
+- composes well with npm packages for features like cookies, proxies, form data, & OAuth
+
+All this in < 100 lines of code.
+
+## install
+
+```
+npm install simple-get
+```
+
+## usage
+
+Note, all these examples also work in the browser with [browserify](http://browserify.org/).
+
+### simple GET request
+
+Doesn't get easier than this:
+
+```js
+const get = require('simple-get')
+
+get('http://example.com', function (err, res) {
+ if (err) throw err
+ console.log(res.statusCode) // 200
+ res.pipe(process.stdout) // `res` is a stream
+})
+```
+
+### even simpler GET request
+
+If you just want the data, and don't want to deal with streams:
+
+```js
+const get = require('simple-get')
+
+get.concat('http://example.com', function (err, res, data) {
+ if (err) throw err
+ console.log(res.statusCode) // 200
+ console.log(data) // Buffer('this is the server response')
+})
+```
+
+### POST, PUT, PATCH, HEAD, DELETE support
+
+For `POST`, call `get.post` or use option `{ method: 'POST' }`.
+
+```js
+const get = require('simple-get')
+
+const opts = {
+ url: 'http://example.com',
+ body: 'this is the POST body'
+}
+get.post(opts, function (err, res) {
+ if (err) throw err
+ res.pipe(process.stdout) // `res` is a stream
+})
+```
+
+#### A more complex example:
+
+```js
+const get = require('simple-get')
+
+get({
+ url: 'http://example.com',
+ method: 'POST',
+ body: 'this is the POST body',
+
+ // simple-get accepts all options that node.js `http` accepts
+ // See: http://nodejs.org/api/http.html#http_http_request_options_callback
+ headers: {
+ 'user-agent': 'my cool app'
+ }
+}, function (err, res) {
+ if (err) throw err
+
+ // All properties/methods from http.IncomingResponse are available,
+ // even if a gunzip/inflate transform stream was returned.
+ // See: http://nodejs.org/api/http.html#http_http_incomingmessage
+ res.setTimeout(10000)
+ console.log(res.headers)
+
+ res.on('data', function (chunk) {
+ // `chunk` is the decoded response, after it's been gunzipped or inflated
+ // (if applicable)
+ console.log('got a chunk of the response: ' + chunk)
+ }))
+
+})
+```
+
+### JSON
+
+You can serialize/deserialize request and response with JSON:
+
+```js
+const get = require('simple-get')
+
+const opts = {
+ method: 'POST',
+ url: 'http://example.com',
+ body: {
+ key: 'value'
+ },
+ json: true
+}
+get.concat(opts, function (err, res, data) {
+ if (err) throw err
+ console.log(data.key) // `data` is an object
+})
+```
+
+### Timeout
+
+You can set a timeout (in milliseconds) on the request with the `timeout` option.
+If the request takes longer than `timeout` to complete, then the entire request
+will fail with an `Error`.
+
+```js
+const get = require('simple-get')
+
+const opts = {
+ url: 'http://example.com',
+ timeout: 2000 // 2 second timeout
+}
+
+get(opts, function (err, res) {})
+```
+
+### One Quick Tip
+
+It's a good idea to set the `'user-agent'` header so the provider can more easily
+see how their resource is used.
+
+```js
+const get = require('simple-get')
+const pkg = require('./package.json')
+
+get('http://example.com', {
+ headers: {
+ 'user-agent': `my-module/${pkg.version} (https://github.com/username/my-module)`
+ }
+})
+```
+
+### Proxies
+
+You can use the [`tunnel`](https://github.com/koichik/node-tunnel) module with the
+`agent` option to work with proxies:
+
+```js
+const get = require('simple-get')
+const tunnel = require('tunnel')
+
+const opts = {
+ url: 'http://example.com',
+ agent: tunnel.httpOverHttp({
+ proxy: {
+ host: 'localhost'
+ }
+ })
+}
+
+get(opts, function (err, res) {})
+```
+
+### Cookies
+
+You can use the [`cookie`](https://github.com/jshttp/cookie) module to include
+cookies in a request:
+
+```js
+const get = require('simple-get')
+const cookie = require('cookie')
+
+const opts = {
+ url: 'http://example.com',
+ headers: {
+ cookie: cookie.serialize('foo', 'bar')
+ }
+}
+
+get(opts, function (err, res) {})
+```
+
+### Form data
+
+You can use the [`form-data`](https://github.com/form-data/form-data) module to
+create POST request with form data:
+
+```js
+const fs = require('fs')
+const get = require('simple-get')
+const FormData = require('form-data')
+const form = new FormData()
+
+form.append('my_file', fs.createReadStream('/foo/bar.jpg'))
+
+const opts = {
+ url: 'http://example.com',
+ body: form
+}
+
+get.post(opts, function (err, res) {})
+```
+
+#### Or, include `application/x-www-form-urlencoded` form data manually:
+
+```js
+const get = require('simple-get')
+
+const opts = {
+ url: 'http://example.com',
+ form: {
+ key: 'value'
+ }
+}
+get.post(opts, function (err, res) {})
+```
+
+### Specifically disallowing redirects
+
+```js
+const get = require('simple-get')
+
+const opts = {
+ url: 'http://example.com/will-redirect-elsewhere',
+ followRedirects: false
+}
+// res.statusCode will be 301, no error thrown
+get(opts, function (err, res) {})
+```
+
+### OAuth
+
+You can use the [`oauth-1.0a`](https://github.com/ddo/oauth-1.0a) module to create
+a signed OAuth request:
+
+```js
+const get = require('simple-get')
+const crypto = require('crypto')
+const OAuth = require('oauth-1.0a')
+
+const oauth = OAuth({
+ consumer: {
+ key: process.env.CONSUMER_KEY,
+ secret: process.env.CONSUMER_SECRET
+ },
+ signature_method: 'HMAC-SHA1',
+ hash_function: (baseString, key) => crypto.createHmac('sha1', key).update(baseString).digest('base64')
+})
+
+const token = {
+ key: process.env.ACCESS_TOKEN,
+ secret: process.env.ACCESS_TOKEN_SECRET
+}
+
+const url = 'https://api.twitter.com/1.1/statuses/home_timeline.json'
+
+const opts = {
+ url: url,
+ headers: oauth.toHeader(oauth.authorize({url, method: 'GET'}, token)),
+ json: true
+}
+
+get(opts, function (err, res) {})
+```
+
+### Throttle requests
+
+You can use [limiter](https://github.com/jhurliman/node-rate-limiter) to throttle requests. This is useful when calling an API that is rate limited.
+
+```js
+const simpleGet = require('simple-get')
+const RateLimiter = require('limiter').RateLimiter
+const limiter = new RateLimiter(1, 'second')
+
+const get = (opts, cb) => limiter.removeTokens(1, () => simpleGet(opts, cb))
+get.concat = (opts, cb) => limiter.removeTokens(1, () => simpleGet.concat(opts, cb))
+
+var opts = {
+ url: 'http://example.com'
+}
+
+get.concat(opts, processResult)
+get.concat(opts, processResult)
+
+function processResult (err, res, data) {
+ if (err) throw err
+ console.log(data.toString())
+}
+```

+# string-width [](https://travis-ci.org/sindresorhus/string-width)
+
+> Get the visual width of a string - the number of columns required to display it
+
+Some Unicode characters are [fullwidth](https://en.wikipedia.org/wiki/Halfwidth_and_fullwidth_forms) and use double the normal width. [ANSI escape codes](http://en.wikipedia.org/wiki/ANSI_escape_code) are stripped and doesn't affect the width.
+
+Useful to be able to measure the actual width of command-line output.
+
+
+## Install
+
+```
+$ npm install --save string-width
+```
+
+
+## Usage
+
+```js
+const stringWidth = require('string-width');
+
+stringWidth('å¤');
+//=> 2
+
+stringWidth('\u001b[1må¤\u001b[22m');
+//=> 2
+
+stringWidth('a');
+//=> 1
+```

+
+
+```bash
+npm install --save string_decoder

+
+***Node-core string_decoder for userland***
+
+This package is a mirror of the string_decoder implementation in Node-core.
+
+Full documentation may be found on the [Node.js website](https://nodejs.org/dist/v8.9.4/docs/api/).
+
+As of version 1.0.0 **string_decoder** uses semantic versioning.
+
+## Previous versions
+
+Previous version numbers match the versions found in Node core, e.g. 0.10.24 matches Node 0.10.24, likewise 0.11.10 matches Node 0.11.10.
+
+## Update
+
+The *build/* directory contains a build script that will scrape the source from the [nodejs/node](https://github.com/nodejs/node) repo given a specific Node version.
+
+## Streams Working Group
+
+`string_decoder` is maintained by the Streams Working Group, which
+oversees the development and maintenance of the Streams API within
+Node.js. The responsibilities of the Streams Working Group include:
+
+* Addressing stream issues on the Node.js issue tracker.
+* Authoring and editing stream documentation within the Node.js project.
+* Reviewing changes to stream subclasses within the Node.js project.
+* Redirecting changes to streams from the Node.js project to this
+ project.
+* Assisting in the implementation of stream providers within Node.js.
+* Recommending versions of `readable-stream` to be included in Node.js.
+* Messaging about the future of streams to give the community advance
+ notice of changes.
+
+See [readable-stream](https://github.com/nodejs/readable-stream) for
+more details.

+# strip-json-comments [](https://travis-ci.org/sindresorhus/strip-json-comments)
+
+> Strip comments from JSON. Lets you use comments in your JSON files!
+
+This is now possible:
+
+```js
+{
+ // rainbows
+ "unicorn": /* ⤠*/ "cake"
+}
+```
+
+It will replace single-line comments `//` and multi-line comments `/**/` with whitespace. This allows JSON error positions to remain as close as possible to the original source.
+
+Also available as a [gulp](https://github.com/sindresorhus/gulp-strip-json-comments)/[grunt](https://github.com/sindresorhus/grunt-strip-json-comments)/[broccoli](https://github.com/sindresorhus/broccoli-strip-json-comments) plugin.
+
+
+## Install
+
+```
+$ npm install --save strip-json-comments
+```
+
+
+## Usage
+
+```js
+const json = '{/*rainbows*/"unicorn":"cake"}';
+
+JSON.parse(stripJsonComments(json));
+//=> {unicorn: 'cake'}
+```
+
+
+## API
+
+### stripJsonComments(input, [options])
+
+#### input
+
+Type: `string`
+
+Accepts a string with JSON and returns a string without comments.
+
+#### options
+
+##### whitespace
+
+Type: `boolean`
+Default: `true`
+
+Replace comments with whitespace instead of stripping them entirely.

+# tar-fs
+
+filesystem bindings for [tar-stream](https://github.com/mafintosh/tar-stream).
+
+```
+npm install tar-fs
+```
+
+[](http://travis-ci.org/mafintosh/tar-fs)
+
+## Usage
+
+tar-fs allows you to pack directories into tarballs and extract tarballs into directories.
+
+It doesn't gunzip for you, so if you want to extract a `.tar.gz` with this you'll need to use something like [gunzip-maybe](https://github.com/mafintosh/gunzip-maybe) in addition to this.
+
+``` js
+var tar = require('tar-fs')
+var fs = require('fs')
+
+// packing a directory
+tar.pack('./my-directory').pipe(fs.createWriteStream('my-tarball.tar'))
+
+// extracting a directory
+fs.createReadStream('my-other-tarball.tar').pipe(tar.extract('./my-other-directory'))
+```
+
+To ignore various files when packing or extracting add a ignore function to the options. `ignore`
+is also an alias for `filter`. Additionally you get `header` if you use ignore while extracting.
+That way you could also filter by metadata.
+
+``` js
+var pack = tar.pack('./my-directory', {
+ ignore: function(name) {
+ return path.extname(name) === '.bin' // ignore .bin files when packing
+ }
+})
+
+var extract = tar.extract('./my-other-directory', {
+ ignore: function(name) {
+ return path.extname(name) === '.bin' // ignore .bin files inside the tarball when extracing
+ }
+})
+
+var extractFilesDirs = tar.extract('./my-other-other-directory', {
+ ignore: function(_, header) {
+ // pass files & directories, ignore e.g. symlinks
+ return header.type !== 'file' && header.type !== 'directory'
+ }
+})
+```
+
+You can also specify which entries to pack using the `entries` option
+
+```js
+var pack = tar.pack('./my-directory', {
+ entries: ['file1', 'subdir/file2'] // only the specific entries will be packed
+})
+```
+
+If you want to modify the headers when packing/extracting add a map function to the options
+
+``` js
+var pack = tar.pack('./my-directory', {
+ map: function(header) {
+ header.name = 'prefixed/'+header.name
+ return header
+ }
+})
+
+var extract = tar.extract('./my-directory', {
+ map: function(header) {
+ header.name = 'another-prefix/'+header.name
+ return header
+ }
+})
+```
+
+Similarly you can use `mapStream` incase you wanna modify the input/output file streams
+
+``` js
+var pack = tar.pack('./my-directory', {
+ mapStream: function(fileStream, header) {
+ // NOTE: the returned stream HAS to have the same length as the input stream.
+ // If not make sure to update the size in the header passed in here.
+ if (path.extname(header.name) === '.js') {
+ return fileStream.pipe(someTransform)
+ }
+ return fileStream;
+ }
+})
+
+var extract = tar.extract('./my-directory', {
+ mapStream: function(fileStream, header) {
+ if (path.extname(header.name) === '.js') {
+ return fileStream.pipe(someTransform)
+ }
+ return fileStream;
+ }
+})
+```
+
+Set `options.fmode` and `options.dmode` to ensure that files/directories extracted have the corresponding modes
+
+``` js
+var extract = tar.extract('./my-directory', {
+ dmode: parseInt(555, 8), // all dirs should be readable
+ fmode: parseInt(444, 8) // all files should be readable
+})
+```
+
+It can be useful to use `dmode` and `fmode` if you are packing/unpacking tarballs between *nix/windows to ensure that all files/directories unpacked are readable.
+
+Alternatively you can set `options.readable` and/or `options.writable` to set the dmode and fmode to readable/writable.
+
+``` js
+var extract = tar.extract('./my-directory', {
+ readable: true, // all dirs and files should be readable
+ writable: true, // all dirs and files should be writable
+})
+```
+
+Set `options.strict` to `false` if you want to ignore errors due to unsupported entry types (like device files)
+
+To dereference symlinks (pack the contents of the symlink instead of the link itself) set `options.dereference` to `true`.
+
+## Copy a directory
+
+Copying a directory with permissions and mtime intact is as simple as
+
+``` js
+tar.pack('source-directory').pipe(tar.extract('dest-directory'))
+```
+
+## Interaction with [`tar-stream`](https://github.com/mafintosh/tar-stream)
+
+Use `finalize: false` and the `finish` hook to
+leave the pack stream open for further entries (see
+[`tar-stream#pack`](https://github.com/mafintosh/tar-stream#packing)),
+and use `pack` to pass an existing pack stream.
+
+``` js
+var mypack = tar.pack('./my-directory', {
+ finalize: false,
+ finish: function(sameAsMypack) {
+ mypack.entry({name: 'generated-file.txt'}, "hello")
+ tar.pack('./other-directory', {
+ pack: sameAsMypack
+ })
+ }
+})
+```
+
+
+## Performance
+
+Packing and extracting a 6.1 GB with 2496 directories and 2398 files yields the following results on my Macbook Air.
+[See the benchmark here](https://gist.github.com/mafintosh/8102201)
+
+* tar-fs: 34.261 seconds
+* [node-tar](https://github.com/isaacs/node-tar): 366.123 seconds (or 10x slower)

+# tar-stream
+
+tar-stream is a streaming tar parser and generator and nothing else. It is streams2 and operates purely using streams which means you can easily extract/parse tarballs without ever hitting the file system.
+
+Note that you still need to gunzip your data if you have a `.tar.gz`. We recommend using [gunzip-maybe](https://github.com/mafintosh/gunzip-maybe) in conjunction with this.
+
+```
+npm install tar-stream
+```
+
+[](http://travis-ci.org/mafintosh/tar-stream)
+[](http://opensource.org/licenses/MIT)
+
+## Usage
+
+tar-stream exposes two streams, [pack](https://github.com/mafintosh/tar-stream#packing) which creates tarballs and [extract](https://github.com/mafintosh/tar-stream#extracting) which extracts tarballs. To [modify an existing tarball](https://github.com/mafintosh/tar-stream#modifying-existing-tarballs) use both.
+
+
+It implementes USTAR with additional support for pax extended headers. It should be compatible with all popular tar distributions out there (gnutar, bsdtar etc)
+
+## Related
+
+If you want to pack/unpack directories on the file system check out [tar-fs](https://github.com/mafintosh/tar-fs) which provides file system bindings to this module.
+
+## Packing
+
+To create a pack stream use `tar.pack()` and call `pack.entry(header, [callback])` to add tar entries.
+
+``` js
+var tar = require('tar-stream')
+var pack = tar.pack() // pack is a streams2 stream
+
+// add a file called my-test.txt with the content "Hello World!"
+pack.entry({ name: 'my-test.txt' }, 'Hello World!')
+
+// add a file called my-stream-test.txt from a stream
+var entry = pack.entry({ name: 'my-stream-test.txt', size: 11 }, function(err) {
+ // the stream was added
+ // no more entries
+ pack.finalize()
+})
+
+entry.write('hello')
+entry.write(' ')
+entry.write('world')
+entry.end()
+
+// pipe the pack stream somewhere
+pack.pipe(process.stdout)
+```
+
+## Extracting
+
+To extract a stream use `tar.extract()` and listen for `extract.on('entry', (header, stream, next) )`
+
+``` js
+var extract = tar.extract()
+
+extract.on('entry', function(header, stream, next) {
+ // header is the tar header
+ // stream is the content body (might be an empty stream)
+ // call next when you are done with this entry
+
+ stream.on('end', function() {
+ next() // ready for next entry
+ })
+
+ stream.resume() // just auto drain the stream
+})
+
+extract.on('finish', function() {
+ // all entries read
+})
+
+pack.pipe(extract)
+```
+
+The tar archive is streamed sequentially, meaning you **must** drain each entry's stream as you get them or else the main extract stream will receive backpressure and stop reading.
+
+## Headers
+
+The header object using in `entry` should contain the following properties.
+Most of these values can be found by stat'ing a file.
+
+``` js
+{
+ name: 'path/to/this/entry.txt',
+ size: 1314, // entry size. defaults to 0
+ mode: 0o644, // entry mode. defaults to to 0o755 for dirs and 0o644 otherwise
+ mtime: new Date(), // last modified date for entry. defaults to now.
+ type: 'file', // type of entry. defaults to file. can be:
+ // file | link | symlink | directory | block-device
+ // character-device | fifo | contiguous-file
+ linkname: 'path', // linked file name
+ uid: 0, // uid of entry owner. defaults to 0
+ gid: 0, // gid of entry owner. defaults to 0
+ uname: 'maf', // uname of entry owner. defaults to null
+ gname: 'staff', // gname of entry owner. defaults to null
+ devmajor: 0, // device major version. defaults to 0
+ devminor: 0 // device minor version. defaults to 0
+}
+```
+
+## Modifying existing tarballs
+
+Using tar-stream it is easy to rewrite paths / change modes etc in an existing tarball.
+
+``` js
+var extract = tar.extract()
+var pack = tar.pack()
+var path = require('path')
+
+extract.on('entry', function(header, stream, callback) {
+ // let's prefix all names with 'tmp'
+ header.name = path.join('tmp', header.name)
+ // write the new entry to the pack stream
+ stream.pipe(pack.entry(header, callback))
+})
+
+extract.on('finish', function() {
+ // all entries done - lets finalize it
+ pack.finalize()
+})
+
+// pipe the old tarball to the extractor
+oldTarballStream.pipe(extract)
+
+// pipe the new tarball the another stream
+pack.pipe(newTarballStream)
+```
+
+## Saving tarball to fs
+
+
+``` js
+var fs = require('fs')
+var tar = require('tar-stream')
+
+var pack = tar.pack() // pack is a streams2 stream
+var path = 'YourTarBall.tar'
+var yourTarball = fs.createWriteStream(path)
+
+// add a file called YourFile.txt with the content "Hello World!"
+pack.entry({name: 'YourFile.txt'}, 'Hello World!', function (err) {
+ if (err) throw err
+ pack.finalize()
+})
+
+// pipe the pack stream to your file
+pack.pipe(yourTarball)
+
+yourTarball.on('close', function () {
+ console.log(path + ' has been written')
+ fs.stat(path, function(err, stats) {
+ if (err) throw err
+ console.log(stats)
+ console.log('Got file info successfully!')
+ })
+})
+```

+### Streams Working Group
+
+The Node.js Streams is jointly governed by a Working Group
+(WG)
+that is responsible for high-level guidance of the project.
+
+The WG has final authority over this project including:
+
+* Technical direction
+* Project governance and process (including this policy)
+* Contribution policy
+* GitHub repository hosting
+* Conduct guidelines
+* Maintaining the list of additional Collaborators
+
+For the current list of WG members, see the project
+[README.md](./README.md#current-project-team-members).
+
+### Collaborators
+
+The readable-stream GitHub repository is
+maintained by the WG and additional Collaborators who are added by the
+WG on an ongoing basis.
+
+Individuals making significant and valuable contributions are made
+Collaborators and given commit-access to the project. These
+individuals are identified by the WG and their addition as
+Collaborators is discussed during the WG meeting.
+
+_Note:_ If you make a significant contribution and are not considered
+for commit-access log an issue or contact a WG member directly and it
+will be brought up in the next WG meeting.
+
+Modifications of the contents of the readable-stream repository are
+made on
+a collaborative basis. Anybody with a GitHub account may propose a
+modification via pull request and it will be considered by the project
+Collaborators. All pull requests must be reviewed and accepted by a
+Collaborator with sufficient expertise who is able to take full
+responsibility for the change. In the case of pull requests proposed
+by an existing Collaborator, an additional Collaborator is required
+for sign-off. Consensus should be sought if additional Collaborators
+participate and there is disagreement around a particular
+modification. See _Consensus Seeking Process_ below for further detail
+on the consensus model used for governance.
+
+Collaborators may opt to elevate significant or controversial
+modifications, or modifications that have not found consensus to the
+WG for discussion by assigning the ***WG-agenda*** tag to a pull
+request or issue. The WG should serve as the final arbiter where
+required.
+
+For the current list of Collaborators, see the project
+[README.md](./README.md#members).
+
+### WG Membership
+
+WG seats are not time-limited. There is no fixed size of the WG.
+However, the expected target is between 6 and 12, to ensure adequate
+coverage of important areas of expertise, balanced with the ability to
+make decisions efficiently.
+
+There is no specific set of requirements or qualifications for WG
+membership beyond these rules.
+
+The WG may add additional members to the WG by unanimous consensus.
+
+A WG member may be removed from the WG by voluntary resignation, or by
+unanimous consensus of all other WG members.
+
+Changes to WG membership should be posted in the agenda, and may be
+suggested as any other agenda item (see "WG Meetings" below).
+
+If an addition or removal is proposed during a meeting, and the full
+WG is not in attendance to participate, then the addition or removal
+is added to the agenda for the subsequent meeting. This is to ensure
+that all members are given the opportunity to participate in all
+membership decisions. If a WG member is unable to attend a meeting
+where a planned membership decision is being made, then their consent
+is assumed.
+
+No more than 1/3 of the WG members may be affiliated with the same
+employer. If removal or resignation of a WG member, or a change of
+employment by a WG member, creates a situation where more than 1/3 of
+the WG membership shares an employer, then the situation must be
+immediately remedied by the resignation or removal of one or more WG
+members affiliated with the over-represented employer(s).
+
+### WG Meetings
+
+The WG meets occasionally on a Google Hangout On Air. A designated moderator
+approved by the WG runs the meeting. Each meeting should be
+published to YouTube.
+
+Items are added to the WG agenda that are considered contentious or
+are modifications of governance, contribution policy, WG membership,
+or release process.
+
+The intention of the agenda is not to approve or review all patches;
+that should happen continuously on GitHub and be handled by the larger
+group of Collaborators.
+
+Any community member or contributor can ask that something be added to
+the next meeting's agenda by logging a GitHub Issue. Any Collaborator,
+WG member or the moderator can add the item to the agenda by adding
+the ***WG-agenda*** tag to the issue.
+
+Prior to each WG meeting the moderator will share the Agenda with
+members of the WG. WG members can add any items they like to the
+agenda at the beginning of each meeting. The moderator and the WG
+cannot veto or remove items.
+
+The WG may invite persons or representatives from certain projects to
+participate in a non-voting capacity.
+
+The moderator is responsible for summarizing the discussion of each
+agenda item and sends it as a pull request after the meeting.
+
+### Consensus Seeking Process
+
+The WG follows a
+[Consensus
+Seeking](http://en.wikipedia.org/wiki/Consensus-seeking_decision-making)
+decision-making model.
+
+When an agenda item has appeared to reach a consensus the moderator
+will ask "Does anyone object?" as a final call for dissent from the
+consensus.
+
+If an agenda item cannot reach a consensus a WG member can call for
+either a closing vote or a vote to table the issue to the next
+meeting. The call for a vote must be seconded by a majority of the WG
+or else the discussion will continue. Simple majority wins.
+
+Note that changes to WG membership require a majority consensus. See
+"WG Membership" above.

+
+***Node.js core streams for userland*** [](https://travis-ci.com/nodejs/readable-stream)
+
+
+[](https://nodei.co/npm/readable-stream/)
+[](https://nodei.co/npm/readable-stream/)
+
+
+[](https://saucelabs.com/u/readabe-stream)
+
+```bash
+npm install --save readable-stream
+```
+
+This package is a mirror of the streams implementations in Node.js.
+
+Full documentation may be found on the [Node.js website](https://nodejs.org/dist/v10.19.0/docs/api/stream.html).
+
+If you want to guarantee a stable streams base, regardless of what version of
+Node you, or the users of your libraries are using, use **readable-stream** *only* and avoid the *"stream"* module in Node-core, for background see [this blogpost](http://r.va.gg/2014/06/why-i-dont-use-nodes-core-stream-module.html).
+
+As of version 2.0.0 **readable-stream** uses semantic versioning.
+
+## Version 3.x.x
+
+v3.x.x of `readable-stream` is a cut from Node 10. This version supports Node 6, 8, and 10, as well as evergreen browsers, IE 11 and latest Safari. The breaking changes introduced by v3 are composed by the combined breaking changes in [Node v9](https://nodejs.org/en/blog/release/v9.0.0/) and [Node v10](https://nodejs.org/en/blog/release/v10.0.0/), as follows:
+
+1. Error codes: https://github.com/nodejs/node/pull/13310,
+ https://github.com/nodejs/node/pull/13291,
+ https://github.com/nodejs/node/pull/16589,
+ https://github.com/nodejs/node/pull/15042,
+ https://github.com/nodejs/node/pull/15665,
+ https://github.com/nodejs/readable-stream/pull/344
+2. 'readable' have precedence over flowing
+ https://github.com/nodejs/node/pull/18994
+3. make virtual methods errors consistent
+ https://github.com/nodejs/node/pull/18813
+4. updated streams error handling
+ https://github.com/nodejs/node/pull/18438
+5. writable.end should return this.
+ https://github.com/nodejs/node/pull/18780
+6. readable continues to read when push('')
+ https://github.com/nodejs/node/pull/18211
+7. add custom inspect to BufferList
+ https://github.com/nodejs/node/pull/17907
+8. always defer 'readable' with nextTick
+ https://github.com/nodejs/node/pull/17979
+
+## Version 2.x.x
+v2.x.x of `readable-stream` is a cut of the stream module from Node 8 (there have been no semver-major changes from Node 4 to 8). This version supports all Node.js versions from 0.8, as well as evergreen browsers and IE 10 & 11.

+
+# Usage
+
+You can swap your `require('stream')` with `require('readable-stream')`
+without any changes, if you are just using one of the main classes and
+functions.
+
+```js
+const {
+ Readable,
+ Writable,
+ Transform,
+ Duplex,
+ pipeline,
+ finished
+} = require('readable-stream')
+````
+
+Note that `require('stream')` will return `Stream`, while
+`require('readable-stream')` will return `Readable`. We discourage using
+whatever is exported directly, but rather use one of the properties as
+shown in the example above.
+
+# Streams Working Group
+
+`readable-stream` is maintained by the Streams Working Group, which
+oversees the development and maintenance of the Streams API within
+Node.js. The responsibilities of the Streams Working Group include:
+
+* Addressing stream issues on the Node.js issue tracker.
+* Authoring and editing stream documentation within the Node.js project.
+* Reviewing changes to stream subclasses within the Node.js project.
+* Redirecting changes to streams from the Node.js project to this
+ project.
+* Assisting in the implementation of stream providers within Node.js.
+* Recommending versions of `readable-stream` to be included in Node.js.
+* Messaging about the future of streams to give the community advance
+ notice of changes.

+// a transform stream is a readable/writable stream where you do
+// something with the data. Sometimes it's called a "filter",
+// but that's not a great name for it, since that implies a thing where
+// some bits pass through, and others are simply ignored. (That would
+// be a valid example of a transform, of course.)
+//
+// While the output is causally related to the input, it's not a
+// necessarily symmetric or synchronous transformation. For example,
+// a zlib stream might take multiple plain-text writes(), and then
+// emit a single compressed chunk some time in the future.
+//
+// Here's how this works:
+//
+// The Transform stream has all the aspects of the readable and writable
+// stream classes. When you write(chunk), that calls _write(chunk,cb)
+// internally, and returns false if there's a lot of pending writes
+// buffered up. When you call read(), that calls _read(n) until
+// there's enough pending readable data buffered up.
+//
+// In a transform stream, the written data is placed in a buffer. When
+// _read(n) is called, it transforms the queued up data, calling the
+// buffered _write cb's as it consumes chunks. If consuming a single
+// written chunk would result in multiple output chunks, then the first
+// outputted bit calls the readcb, and subsequent chunks just go into
+// the read buffer, and will cause it to emit 'readable' if necessary.
+//
+// This way, back-pressure is actually determined by the reading side,
+// since _read has to be called to start processing a new chunk. However,
+// a pathological inflate type of transform can cause excessive buffering
+// here. For example, imagine a stream where every byte of input is
+// interpreted as an integer from 0-255, and then results in that many
+// bytes of output. Writing the 4 bytes {ff,ff,ff,ff} would result in
+// 1kb of data being output. In this case, you could write a very small
+// amount of input, and end up with a very large amount of output. In
+// such a pathological inflating mechanism, there'd be no way to tell
+// the system to stop doing the transform. A single 4MB write could
+// cause the system to run out of memory.
+//
+// However, even in such a pathological case, only a single written chunk
+// would be consumed, and then the rest would wait (un-transformed) until
+// the results of the previous transformed chunk were consumed.

+==============
+### The Node.js `util.deprecate()` function with browser support
+
+In Node.js, this module simply re-exports the `util.deprecate()` function.
+
+In the web browser (i.e. via browserify), a browser-specific implementation
+of the `util.deprecate()` function is used.
+
+
+## API
+
+A `deprecate()` function is the only thing exposed by this module.
+
+``` javascript
+// setup:
+exports.foo = deprecate(foo, 'foo() is deprecated, use bar() instead');
+
+
+// users see:
+foo();
+// foo() is deprecated, use bar() instead
+foo();
+foo();

+wide-align
+----------
+
+A wide-character aware text alignment function for use in terminals / on the
+console.
+
+### Usage
+
+```
+var align = require('wide-align')
+
+// Note that if you view this on a unicode console, all of the slashes are
+// aligned. This is because on a console, all narrow characters are
+// an en wide and all wide characters are an em. In browsers, this isn't
+// held to and wide characters like "å¤" can be less than two narrow
+// characters even with a fixed width font.
+
+console.log(align.center('abc', 10)) // ' abc '
+console.log(align.center('å¤å¤å¤', 10)) // ' å¤å¤å¤ '
+console.log(align.left('abc', 10)) // 'abc '
+console.log(align.left('å¤å¤å¤', 10)) // 'å¤å¤å¤ '
+console.log(align.right('abc', 10)) // ' abc'
+console.log(align.right('å¤å¤å¤', 10)) // ' å¤å¤å¤'
+```
+
+### Functions
+
+#### `align.center(str, length)` → `str`
+
+Returns *str* with spaces added to both sides such that that it is *length*
+chars long and centered in the spaces.
+
+#### `align.left(str, length)` → `str`
+
+Returns *str* with spaces to the right such that it is *length* chars long.
+
+### `align.right(str, length)` → `str`
+
+Returns *str* with spaces to the left such that it is *length* chars long.
+
+### Origins
+
+These functions were originally taken from
+[cliui](https://npmjs.com/package/cliui). Changes include switching to the
+MUCH faster pad generation function from
+[lodash](https://npmjs.com/package/lodash), making center alignment pad
+both sides and adding left alignment.
