+# `@actions/core`
+
+> Core functions for setting results, logging, registering secrets and exporting variables across actions
+
+## Usage
+
+### Import the package
+
+```js
+// javascript
+const core = require('@actions/core');
+
+// typescript
+import * as core from '@actions/core';
+```
+
+#### Inputs/Outputs
+
+Action inputs can be read with `getInput` which returns a `string` or `getBooleanInput` which parses a boolean based on the [yaml 1.2 specification](https://yaml.org/spec/1.2/spec.html#id2804923). If `required` set to be false, the input should have a default value in `action.yml`.
+
+Outputs can be set with `setOutput` which makes them available to be mapped into inputs of other actions to ensure they are decoupled.
+
+```js
+const myInput = core.getInput('inputName', { required: true });
+const myBooleanInput = core.getBooleanInput('booleanInputName', { required: true });
+const myMultilineInput = core.getMultilineInput('multilineInputName', { required: true });
+core.setOutput('outputKey', 'outputVal');
+```
+
+#### Exporting variables
+
+Since each step runs in a separate process, you can use `exportVariable` to add it to this step and future steps environment blocks.
+
+```js
+core.exportVariable('envVar', 'Val');
+```
+
+#### Setting a secret
+
+Setting a secret registers the secret with the runner to ensure it is masked in logs.
+
+```js
+core.setSecret('myPassword');
+```
+
+#### PATH Manipulation
+
+To make a tool's path available in the path for the remainder of the job (without altering the machine or containers state), use `addPath`.  The runner will prepend the path given to the jobs PATH.
+
+```js
+core.addPath('/path/to/mytool');
+```
+
+#### Exit codes
+
+You should use this library to set the failing exit code for your action.  If status is not set and the script runs to completion, that will lead to a success.
+
+```js
+const core = require('@actions/core');
+
+try {
+  // Do stuff
+}
+catch (err) {
+  // setFailed logs the message and sets a failing exit code
+  core.setFailed(`Action failed with error ${err}`);
+}
+```
+
+Note that `setNeutral` is not yet implemented in actions V2 but equivalent functionality is being planned.
+
+#### Logging
+
+Finally, this library provides some utilities for logging. Note that debug logging is hidden from the logs by default. This behavior can be toggled by enabling the [Step Debug Logs](../../docs/action-debugging.md#step-debug-logs).
+
+```js
+const core = require('@actions/core');
+
+const myInput = core.getInput('input');
+try {
+  core.debug('Inside try block');
+  
+  if (!myInput) {
+    core.warning('myInput was not set');
+  }
+  
+  if (core.isDebug()) {
+    // curl -v https://github.com
+  } else {
+    // curl https://github.com
+  }
+
+  // Do stuff
+  core.info('Output to the actions build log')
+
+  core.notice('This is a message that will also emit an annotation')
+}
+catch (err) {
+  core.error(`Error ${err}, action may still succeed though`);
+}
+```
+
+This library can also wrap chunks of output in foldable groups.
+
+```js
+const core = require('@actions/core')
+
+// Manually wrap output
+core.startGroup('Do some function')
+doSomeFunction()
+core.endGroup()
+
+// Wrap an asynchronous function call
+const result = await core.group('Do something async', async () => {
+  const response = await doSomeHTTPRequest()
+  return response
+})
+```
+
+#### Annotations
+
+This library has 3 methods that will produce [annotations](https://docs.github.com/en/rest/reference/checks#create-a-check-run). 
+```js
+core.error('This is a bad error. This will also fail the build.')
+
+core.warning('Something went wrong, but it\'s not bad enough to fail the build.')
+
+core.notice('Something happened that you might want to know about.')
+```
+
+These will surface to the UI in the Actions page and on Pull Requests. They look something like this:
+
+![Annotations Image](../../docs/assets/annotations.png)
+
+These annotations can also be attached to particular lines and columns of your source files to show exactly where a problem is occuring. 
+
+These options are: 
+```typescript
+export interface AnnotationProperties {
+  /**
+   * A title for the annotation.
+   */
+  title?: string
+
+  /**
+   * The name of the file for which the annotation should be created.
+   */
+  file?: string
+
+  /**
+   * The start line for the annotation.
+   */
+  startLine?: number
+
+  /**
+   * The end line for the annotation. Defaults to `startLine` when `startLine` is provided.
+   */
+  endLine?: number
+
+  /**
+   * The start column for the annotation. Cannot be sent when `startLine` and `endLine` are different values.
+   */
+  startColumn?: number
+
+  /**
+   * The start column for the annotation. Cannot be sent when `startLine` and `endLine` are different values.
+   * Defaults to `startColumn` when `startColumn` is provided.
+   */
+  endColumn?: number
+}
+```
+
+#### Styling output
+
+Colored output is supported in the Action logs via standard [ANSI escape codes](https://en.wikipedia.org/wiki/ANSI_escape_code). 3/4 bit, 8 bit and 24 bit colors are all supported.
+
+Foreground colors:
+
+```js
+// 3/4 bit
+core.info('\u001b[35mThis foreground will be magenta')
+
+// 8 bit
+core.info('\u001b[38;5;6mThis foreground will be cyan')
+
+// 24 bit
+core.info('\u001b[38;2;255;0;0mThis foreground will be bright red')
+```
+
+Background colors:
+
+```js
+// 3/4 bit
+core.info('\u001b[43mThis background will be yellow');
+
+// 8 bit
+core.info('\u001b[48;5;6mThis background will be cyan')
+
+// 24 bit
+core.info('\u001b[48;2;255;0;0mThis background will be bright red')
+```
+
+Special styles:
+
+```js
+core.info('\u001b[1mBold text')
+core.info('\u001b[3mItalic text')
+core.info('\u001b[4mUnderlined text')
+```
+
+ANSI escape codes can be combined with one another:
+
+```js
+core.info('\u001b[31;46mRed foreground with a cyan background and \u001b[1mbold text at the end');
+```
+
+> Note: Escape codes reset at the start of each line
+
+```js
+core.info('\u001b[35mThis foreground will be magenta')
+core.info('This foreground will reset to the default')
+```
+
+Manually typing escape codes can be a little difficult, but you can use third party modules such as [ansi-styles](https://github.com/chalk/ansi-styles).
+
+```js
+const style = require('ansi-styles');
+core.info(style.color.ansi16m.hex('#abcdef') + 'Hello world!')
+```
+
+#### Action state
+
+You can use this library to save state and get state for sharing information between a given wrapper action:
+
+**action.yml**:
+
+```yaml
+name: 'Wrapper action sample'
+inputs:
+  name:
+    default: 'GitHub'
+runs:
+  using: 'node12'
+  main: 'main.js'
+  post: 'cleanup.js'
+```
+
+In action's `main.js`:
+
+```js
+const core = require('@actions/core');
+
+core.saveState("pidToKill", 12345);
+```
+
+In action's `cleanup.js`:
+
+```js
+const core = require('@actions/core');
+
+var pid = core.getState("pidToKill");
+
+process.kill(pid);
+```
+
+#### OIDC Token
+
+You can use these methods to interact with the GitHub OIDC provider and get a JWT ID token which would help to get access token from third party cloud providers.
+
+**Method Name**: getIDToken()
+
+**Inputs**
+
+audience : optional
+
+**Outputs**
+
+A [JWT](https://jwt.io/) ID Token
+
+In action's `main.ts`:
+```js
+const core = require('@actions/core');
+async function getIDTokenAction(): Promise<void> {
+  
+   const audience = core.getInput('audience', {required: false})
+   
+   const id_token1 = await core.getIDToken()            // ID Token with default audience
+   const id_token2 = await core.getIDToken(audience)    // ID token with custom audience
+   
+   // this id_token can be used to get access token from third party cloud providers
+}
+getIDTokenAction()
+```
+
+In action's `actions.yml`:
+
+```yaml
+name: 'GetIDToken'
+description: 'Get ID token from Github OIDC provider'
+inputs:
+  audience:  
+    description: 'Audience for which the ID token is intended for'
+    required: false
+outputs:
+  id_token1: 
+    description: 'ID token obtained from OIDC provider'
+  id_token2: 
+    description: 'ID token obtained from OIDC provider'
+runs:
+  using: 'node12'
+  main: 'dist/index.js'
+```

+# Actions Http-Client
+
+[![Http Status](https://github.com/actions/http-client/workflows/http-tests/badge.svg)](https://github.com/actions/http-client/actions)
+
+A lightweight HTTP client optimized for use with actions, TypeScript with generics and async await.
+
+## Features
+
+  - HTTP client with TypeScript generics and async/await/Promises
+  - Typings included so no need to acquire separately (great for intellisense and no versioning drift)
+  - [Proxy support](https://help.github.com/en/actions/automating-your-workflow-with-github-actions/about-self-hosted-runners#using-a-proxy-server-with-self-hosted-runners) just works with actions and the runner
+  - Targets ES2019 (runner runs actions with node 12+).  Only supported on node 12+.
+  - Basic, Bearer and PAT Support out of the box.  Extensible handlers for others.
+  - Redirects supported
+
+Features and releases [here](./RELEASES.md)
+
+## Install
+
+```
+npm install @actions/http-client --save
+```
+
+## Samples
+
+See the [HTTP](./__tests__) tests for detailed examples.
+
+## Errors
+
+### HTTP
+
+The HTTP client does not throw unless truly exceptional.
+
+* A request that successfully executes resulting in a 404, 500 etc... will return a response object with a status code and a body.
+* Redirects (3xx) will be followed by default.
+
+See [HTTP tests](./__tests__) for detailed examples.
+
+## Debugging
+
+To enable detailed console logging of all HTTP requests and responses, set the NODE_DEBUG environment varible:
+
+```
+export NODE_DEBUG=http
+```
+
+## Node support
+
+The http-client is built using the latest LTS version of Node 12. It may work on previous node LTS versions but it's tested and officially supported on Node12+.
+
+## Support and Versioning
+
+We follow semver and will hold compatibility between major versions and increment the minor version with new features and capabilities (while holding compat).
+
+## Contributing
+
+We welcome PRs.  Please create an issue and if applicable, a design before proceeding with code.
+
+once:
+
+```bash
+$ npm install
+```
+
+To build:
+
+```bash
+$ npm run build
+```
+
+To run all tests:
+```bash
+$ npm test
+```

+## Releases
+
+## 1.0.10
+
+Contains a bug fix where proxy is defined without a user and password. see [PR here](https://github.com/actions/http-client/pull/42)   
+
+## 1.0.9
+Throw HttpClientError instead of a generic Error from the \<verb>Json() helper methods when the server responds with a non-successful status code. 
+
+## 1.0.8
+Fixed security issue where a redirect (e.g. 302) to another domain would pass headers.  The fix was to strip the authorization header if the hostname was different.  More [details in PR #27](https://github.com/actions/http-client/pull/27)
+
+## 1.0.7
+Update NPM dependencies and add 429 to the list of HttpCodes
+
+## 1.0.6
+Automatically sends Content-Type and Accept application/json headers for \<verb>Json() helper methods if not set in the client or parameters.
+
+## 1.0.5
+Adds \<verb>Json() helper methods for json over http scenarios.
+
+## 1.0.4
+Started to add \<verb>Json() helper methods.  Do not use this release for that.  Use >= 1.0.5 since there was an issue with types.
+
+## 1.0.1 to 1.0.3
+Adds proxy support.

-### Install
-
-```sh
-npm install -g @choojs/findup
-```
-
-### Usage
-
-Find up a file in ancestor's dir
-
-
-    .
-    ├── config.json

-### Options
-
-- `maxdepth`: (Number, default -1) How far to traverse before giving up. If maxdepth is `-1`, then there is no limit.
-
-#### Async
-
-findup(dir, fileName, options, callback)
-findup(dir, iterator, options, callback) with `iterator(dir, cb)` where cb only accept `true` or `false`
-
-```js
-var findup = require('@choojs/findup');
-
-
-findup(__dirname + '/f/e/d/c/b/a', 'config.json', function(err, dir){
-  // if(e) e === new Error('not found')

-});
-```
-
-findup return an EventEmitter. 3 events are emitted: `found`, `error`, `end`
-
-`found` event is emitted each time a file is found.
-
-You can stop the traversing by calling `stop` manually.
-
-```js
-fup.on('found', function(dir){
-  // dir === '/f/e/d/c'
-  fup.stop();
-});
-```
-
-`error` event is emitted when error happens
-
-```js
-fup.on('error', function(e){
-  // if(e) e === new Error('not found')
-});
-```
-
-`end` event is emitted at the end of the traversing or after `stop()` is
-called.
-
-```js
-fup.on('end', function(){
-  // happy end
-});
-```
-
-#### Sync
-
-findup(dir, fileName)
-findup(dir, iteratorSync) with `iteratorSync` return `true` or `false`
-```js
-var findup = require('@choojs/findup');

+base64-js
+=========
+
+`base64-js` does basic base64 encoding/decoding in pure JS.
+
+[![build status](https://secure.travis-ci.org/beatgammit/base64-js.png)](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

+# bl *(BufferList)*
+
+[![Build Status](https://api.travis-ci.com/rvagg/bl.svg?branch=master)](https://travis-ci.com/rvagg/bl/)
+
+**A Node.js Buffer list collector, reader and streamer thingy.**
+
+[![NPM](https://nodei.co/npm/bl.svg)](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'))
+```

+### 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&mdash;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')
+```

@@ -0,0 +1,136 @@
+### 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.

+
+```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

+[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-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).
+
+[![JavaScript Style Guide](https://cdn.rawgit.com/feross/standard/master/badge.svg)](https://github.com/feross/standard)
+
+To test that the code conforms to the style, `npm install` and run:
+
+    ./node_modules/.bin/standard
