+# Readability.js
+
+A standalone version of the readability library used for Firefox Reader View.
+
+## Usage on the web
+
+To parse a document, you must create a new `Readability` object from a DOM document object, and then call `parse()`. Here's an example:
+
+```javascript
+var article = new Readability(document).parse();
+```
+
+This `article` object will contain the following properties:
+
+* `title`: article title
+* `content`: HTML string of processed article content
+* `length`: length of an article, in characters
+* `excerpt`: article description, or short excerpt from the content
+* `byline`: author metadata
+* `dir`: content direction
+
+If you're using Readability on the web, you will likely be able to use a `document` reference
+from elsewhere (e.g. fetched via XMLHttpRequest, in a same-origin `<iframe>` you have access to, etc.).
+
+### Optional
+
+Readability's `parse()` works by modifying the DOM. This removes some elements in the web page.
+You could avoid this by passing the clone of the `document` object while creating a `Readability` object.
+
+```
+var documentClone = document.cloneNode(true); 
+var article = new Readability(documentClone).parse();
+```
+
+## Usage from Node.js
+
+Readability is available on npm:
+
+```bash
+npm install @mozilla/readability
+```
+
+In Node.js, you won't generally have a DOM document object. To obtain one, you can use external
+libraries like [jsdom](https://github.com/jsdom/jsdom). While this repository contains a parser of
+its own (`JSDOMParser`), that is restricted to reading XML-compatible markup and therefore we do
+not recommend it for general use.
+
+If you're using `jsdom` to create a DOM object, you should ensure that the page doesn't run (page)
+scripts (avoid fetching remote resources etc.) as well as passing it the page's URI as the `url`
+property of the `options` object you pass the `JSDOM` constructor.
+
+### Example:
+
+```js
+var { Readability } = require('@mozilla/readability');
+var JSDOM = require('jsdom').JSDOM;
+var doc = new JSDOM("<body>Here's a bunch of text</body>", {
+  url: "https://www.example.com/the-page-i-got-the-source-from"
+});
+let reader = new Readability(doc.window.document);
+let article = reader.parse();
+```
+
+## What's Readability-readerable?
+
+It's a quick-and-dirty way of figuring out if it's plausible that the contents of a given
+document are suitable for processing with Readability. It is likely to produce both false
+positives and false negatives. The reason it exists is to avoid bogging down a time-sensitive
+process (like loading and showing the user a webpage) with the complex logic in the core of
+Readability. Improvements to its logic (while not deteriorating its performance) are very
+welcome.
+
+## Security
+
+If you're going to use Readability with untrusted input (whether in HTML or DOM form), we
+**strongly** recommend you use a sanitizer library like
+[DOMPurify](https://github.com/cure53/DOMPurify) to avoid script injection when you use
+the output of Readability. We would also recommend using
+[CSP](https://developer.mozilla.org/en-US/docs/Web/HTTP/CSP) to add further defense-in-depth
+restrictions to what you allow the resulting content to do. The Firefox integration of
+reader mode uses both of these techniques itself. Sanitizing unsafe content out of the input
+is explicitly not something we aim to do as part of Readability itself - there are other
+good sanitizer libraries out there, use them!
+
+## Contributing
+
+[![Build Status](https://travis-ci.org/mozilla/readability.svg?branch=master)](https://travis-ci.org/mozilla/readability)
+
+For outstanding issues, see the issue list in this repo, as well as this [bug list](https://bugzilla.mozilla.org/buglist.cgi?component=Reader%20Mode&product=Toolkit&bug_status=__open__&limit=0).
+
+Any changes to Readability.js itself should be reviewed by an [appropriate Firefox/toolkit peer](https://wiki.mozilla.org/Modules/Firefox), such as [@gijsk](https://github.com/gijsk), since these changes will be merged to mozilla-central and shipped in Firefox.
+
+To test local changes to Readability.js, you can use the [automated tests](#tests). There's a [node script](https://github.com/mozilla/readability/blob/master/test/generate-testcase.js) to help you create new ones.
+
+## Tests
+
+Please run [eslint](http://eslint.org/) as a first check that your changes are valid JS and adhere to our style guidelines.
+
+To run the test suite:
+
+    $ mocha test/test-*.js
+
+To run a specific test page by its name:
+
+    $ mocha test/test-*.js -g 001
+
+To run the test suite in TDD mode:
+
+    $ mocha test/test-*.js -w
+
+Combo time:
+
+    $ mocha test/test-*.js -w -g 001
+
+## Benchmarks
+
+Benchmarks for all test pages:
+
+    $ npm run perf
+
+Reference benchmark:
+
+    $ npm run perf-reference

+# abab [![npm version](https://badge.fury.io/js/abab.svg)](https://www.npmjs.com/package/abab) [![Build Status](https://travis-ci.org/jsdom/abab.svg?branch=master)](https://travis-ci.org/jsdom/abab)
+
+A JavaScript module that implements `window.atob` and `window.btoa` according the forgiving-base64 algorithm in the [Infra Standard](https://infra.spec.whatwg.org/#forgiving-base64). The original code was forked from [w3c/web-platform-tests](https://github.com/w3c/web-platform-tests/blob/master/html/webappapis/atob/base64.html).
+
+Compatibility: Node.js version 3+ and all major browsers.
+
+Install with `npm`:
+
+```sh
+npm install abab
+```
+
+## API
+
+### `btoa` (base64 encode)
+
+```js
+const { btoa } = require('abab');
+btoa('Hello, world!'); // 'SGVsbG8sIHdvcmxkIQ=='
+```
+
+### `atob` (base64 decode)
+
+```js 
+const { atob } = require('abab');
+atob('SGVsbG8sIHdvcmxkIQ=='); // 'Hello, world!'
+```
+
+#### Valid characters
+
+[Per the spec](https://html.spec.whatwg.org/multipage/webappapis.html#atob:dom-windowbase64-btoa-3), `btoa` will accept strings "containing only characters in the range `U+0000` to `U+00FF`." If passed a string with characters above `U+00FF`, `btoa` will return `null`. If `atob` is passed a string that is not base64-valid, it will also return `null`. In both cases when `null` is returned, the spec calls for throwing a `DOMException` of type `InvalidCharacterError`.
+
+## Browsers
+
+If you want to include just one of the methods to save bytes in your client-side code, you can `require` the desired module directly.
+
+```js
+const atob = require('abab/lib/atob');
+const btoa = require('abab/lib/btoa');
+```
+
+## Development
+
+If you're **submitting a PR** or **deploying to npm**, please use the [checklists in CONTRIBUTING.md](CONTRIBUTING.md#checklists).
+
+## Remembering what `atob` and `btoa` stand for
+
+Base64 comes from IETF [RFC 4648](https://tools.ietf.org/html/rfc4648#section-4) (2006). 
+
+- **`btoa`**, the encoder function, stands for **binary** to **ASCII**, meaning it converts any binary input into a subset of **ASCII** (Base64).
+- **`atob`**, the decoder function, converts **ASCII** (or Base64) to its original **binary** format.

+Higher level content negotiation based on [negotiator](https://www.npmjs.com/package/negotiator).
+Extracted from [koa](https://www.npmjs.com/package/koa) for general use.
+
+In addition to negotiator, it allows:
+
+- Allows types as an array or arguments list, ie `(['text/html', 'application/json'])`
+  as well as `('text/html', 'application/json')`.
+- Allows type shorthands such as `json`.
+- Returns `false` when no types match
+- Treats non-existent headers as `*`
+
+## Installation
+
+This is a [Node.js](https://nodejs.org/en/) module available through the
+[npm registry](https://www.npmjs.com/). Installation is done using the
+[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
+
+```sh
+$ npm install accepts
+```
+
+## API
+
+<!-- eslint-disable no-unused-vars -->
+
+```js
+var accepts = require('accepts')
+```
+
+### accepts(req)
+
+Create a new `Accepts` object for the given `req`.
+
+#### .charset(charsets)
+
+Return the first accepted charset. If nothing in `charsets` is accepted,
+then `false` is returned.
+
+#### .charsets()
+
+Return the charsets that the request accepts, in the order of the client's
+preference (most preferred first).
+
+#### .encoding(encodings)
+
+Return the first accepted encoding. If nothing in `encodings` is accepted,
+then `false` is returned.
+
+#### .encodings()
+
+Return the encodings that the request accepts, in the order of the client's
+preference (most preferred first).
+
+#### .language(languages)
+
+Return the first accepted language. If nothing in `languages` is accepted,
+then `false` is returned.
+
+#### .languages()
+
+Return the languages that the request accepts, in the order of the client's
+preference (most preferred first).
+
+#### .type(types)
+
+Return the first accepted type (and it is returned as the same text as what
+appears in the `types` array). If nothing in `types` is accepted, then `false`
+is returned.
+
+The `types` array can contain full MIME types or file extensions. Any value
+that is not a full MIME types is passed to `require('mime-types').lookup`.
+
+#### .types()
+
+Return the types that the request accepts, in the order of the client's
+preference (most preferred first).
+

+### Simple type negotiation
+
+This simple example shows how to use `accepts` to return a different typed
+respond body based on what the client wants to accept. The server lists it's
+preferences in order and will get back the best match between the client and
+server.
+
+```js
+var accepts = require('accepts')
+var http = require('http')
+
+function app (req, res) {
+  var accept = accepts(req)
+
+  // the order of this list is significant; should be server preferred order
+  switch (accept.type(['json', 'html'])) {
+    case 'json':
+      res.setHeader('Content-Type', 'application/json')
+      res.write('{"hello":"world!"}')
+      break
+    case 'html':
+      res.setHeader('Content-Type', 'text/html')
+      res.write('<b>hello, world!</b>')
+      break
+    default:
+      // the fallback is text/plain, so no need to specify it above
+      res.setHeader('Content-Type', 'text/plain')
+      res.write('hello, world!')
+      break
+  }
+
+  res.end()
+}
+
+http.createServer(app).listen(3000)
+```
+
+You can test this out with the cURL program:
+```sh
+curl -I -H'Accept: text/html' http://localhost:3000/
+```

+# Acorn AST walker
+
+An abstract syntax tree walker for the
+[ESTree](https://github.com/estree/estree) format.
+
+## Community
+
+Acorn is open source software released under an
+[MIT license](https://github.com/acornjs/acorn/blob/master/acorn-walk/LICENSE).
+
+You are welcome to
+[report bugs](https://github.com/acornjs/acorn/issues) or create pull
+requests on [github](https://github.com/acornjs/acorn). For questions
+and discussion, please use the
+[Tern discussion forum](https://discuss.ternjs.net).
+
+## Installation
+
+The easiest way to install acorn is from [`npm`](https://www.npmjs.com/):
+
+```sh
+npm install acorn-walk
+```
+
+Alternately, you can download the source and build acorn yourself:
+
+```sh
+git clone https://github.com/acornjs/acorn.git
+cd acorn
+npm install
+```
+
+## Interface
+
+An algorithm for recursing through a syntax tree is stored as an
+object, with a property for each tree node type holding a function
+that will recurse through such a node. There are several ways to run
+such a walker.
+
+**simple**`(node, visitors, base, state)` does a 'simple' walk over a
+tree. `node` should be the AST node to walk, and `visitors` an object
+with properties whose names correspond to node types in the [ESTree
+spec](https://github.com/estree/estree). The properties should contain
+functions that will be called with the node object and, if applicable
+the state at that point. The last two arguments are optional. `base`
+is a walker algorithm, and `state` is a start state. The default
+walker will simply visit all statements and expressions and not
+produce a meaningful state. (An example of a use of state is to track
+scope at each point in the tree.)
+
+```js
+const acorn = require("acorn")
+const walk = require("acorn-walk")
+
+walk.simple(acorn.parse("let x = 10"), {
+  Literal(node) {
+    console.log(`Found a literal: ${node.value}`)
+  }
+})
+```
+
+**ancestor**`(node, visitors, base, state)` does a 'simple' walk over
+a tree, building up an array of ancestor nodes (including the current node)
+and passing the array to the callbacks as a third parameter.
+
+```js
+const acorn = require("acorn")
+const walk = require("acorn-walk")
+
+walk.ancestor(acorn.parse("foo('hi')"), {
+  Literal(_, ancestors) {
+    console.log("This literal's ancestors are:", ancestors.map(n => n.type))
+  }
+})
+```
+
+**recursive**`(node, state, functions, base)` does a 'recursive'
+walk, where the walker functions are responsible for continuing the
+walk on the child nodes of their target node. `state` is the start
+state, and `functions` should contain an object that maps node types
+to walker functions. Such functions are called with `(node, state, c)`
+arguments, and can cause the walk to continue on a sub-node by calling
+the `c` argument on it with `(node, state)` arguments. The optional
+`base` argument provides the fallback walker functions for node types
+that aren't handled in the `functions` object. If not given, the
+default walkers will be used.
+
+**make**`(functions, base)` builds a new walker object by using the
+walker functions in `functions` and filling in the missing ones by
+taking defaults from `base`.
+
+**full**`(node, callback, base, state)` does a 'full' walk over a
+tree, calling the callback with the arguments (node, state, type) for
+each node
+
+**fullAncestor**`(node, callback, base, state)` does a 'full' walk
+over a tree, building up an array of ancestor nodes (including the
+current node) and passing the array to the callbacks as a third
+parameter.
+
+```js
+const acorn = require("acorn")
+const walk = require("acorn-walk")
+
+walk.full(acorn.parse("1 + 1"), node => {
+  console.log(`There's a ${node.type} node at ${node.ch}`)
+})
+```
+
+**findNodeAt**`(node, start, end, test, base, state)` tries to locate
+a node in a tree at the given start and/or end offsets, which
+satisfies the predicate `test`. `start` and `end` can be either `null`
+(as wildcard) or a number. `test` may be a string (indicating a node
+type) or a function that takes `(nodeType, node)` arguments and
+returns a boolean indicating whether this node is interesting. `base`
+and `state` are optional, and can be used to specify a custom walker.
+Nodes are tested from inner to outer, so if two nodes match the
+boundaries, the inner one will be preferred.
+
+**findNodeAround**`(node, pos, test, base, state)` is a lot like
+`findNodeAt`, but will match any node that exists 'around' (spanning)
+the given position.
+
+**findNodeAfter**`(node, pos, test, base, state)` is similar to
+`findNodeAround`, but will match all nodes *after* the given position
+(testing outer nodes before inner nodes).

+## 4.0.0 (2016-08-07)
+
+### Breaking changes
+
+The default `ecmaVersion` option value is now 7.
+

+
+## 3.0.0 (2016-02-10)

+# Acorn
+
+A tiny, fast JavaScript parser written in JavaScript.
+
+## Community
+
+Acorn is open source software released under an
+[MIT license](https://github.com/acornjs/acorn/blob/master/acorn/LICENSE).
+
+You are welcome to
+[report bugs](https://github.com/acornjs/acorn/issues) or create pull
+requests on [github](https://github.com/acornjs/acorn). For questions
+and discussion, please use the
+[Tern discussion forum](https://discuss.ternjs.net).
+
+## Installation
+
+The easiest way to install acorn is from [`npm`](https://www.npmjs.com/):
+
+```sh
+npm install acorn
+```
+
+Alternately, you can download the source and build acorn yourself:
+
+```sh
+git clone https://github.com/acornjs/acorn.git
+cd acorn
+npm install
+```
+
+## Interface
+
+**parse**`(input, options)` is the main interface to the library. The
+`input` parameter is a string, `options` can be undefined or an object
+setting some of the options listed below. The return value will be an
+abstract syntax tree object as specified by the [ESTree
+spec](https://github.com/estree/estree).
+
+```javascript
+let acorn = require("acorn");
+console.log(acorn.parse("1 + 1"));
+```
+
+When encountering a syntax error, the parser will raise a
+`SyntaxError` object with a meaningful message. The error object will
+have a `pos` property that indicates the string offset at which the
+error occurred, and a `loc` object that contains a `{line, column}`
+object referring to that same position.
+
+Options can be provided by passing a second argument, which should be
+an object containing any of these fields:
+
+- **ecmaVersion**: Indicates the ECMAScript version to parse. Must be
+  either 3, 5, 6 (2015), 7 (2016), 8 (2017), 9 (2018), 10 (2019) or 11
+  (2020, partial support). This influences support for strict mode,
+  the set of reserved words, and support for new syntax features.
+  Default is 10.
+
+  **NOTE**: Only 'stage 4' (finalized) ECMAScript features are being
+  implemented by Acorn. Other proposed new features can be implemented
+  through plugins.
+
+- **sourceType**: Indicate the mode the code should be parsed in. Can be
+  either `"script"` or `"module"`. This influences global strict mode
+  and parsing of `import` and `export` declarations.
+
+  **NOTE**: If set to `"module"`, then static `import` / `export` syntax
+  will be valid, even if `ecmaVersion` is less than 6.
+
+- **onInsertedSemicolon**: If given a callback, that callback will be
+  called whenever a missing semicolon is inserted by the parser. The
+  callback will be given the character offset of the point where the
+  semicolon is inserted as argument, and if `locations` is on, also a
+  `{line, column}` object representing this position.
+
+- **onTrailingComma**: Like `onInsertedSemicolon`, but for trailing
+  commas.
+
+- **allowReserved**: If `false`, using a reserved word will generate
+  an error. Defaults to `true` for `ecmaVersion` 3, `false` for higher
+  versions. When given the value `"never"`, reserved words and
+  keywords can also not be used as property names (as in Internet
+  Explorer's old parser).
+
+- **allowReturnOutsideFunction**: By default, a return statement at
+  the top level raises an error. Set this to `true` to accept such
+  code.
+
+- **allowImportExportEverywhere**: By default, `import` and `export`
+  declarations can only appear at a program's top level. Setting this
+  option to `true` allows them anywhere where a statement is allowed.
+  
+- **allowAwaitOutsideFunction**: By default, `await` expressions can
+  only appear inside `async` functions. Setting this option to
+  `true` allows to have top-level `await` expressions. They are
+  still not allowed in non-`async` functions, though.
+
+- **allowHashBang**: When this is enabled (off by default), if the
+  code starts with the characters `#!` (as in a shellscript), the
+  first line will be treated as a comment.
+
+- **locations**: When `true`, each node has a `loc` object attached
+  with `start` and `end` subobjects, each of which contains the
+  one-based line and zero-based column numbers in `{line, column}`
+  form. Default is `false`.
+
+- **onToken**: If a function is passed for this option, each found
+  token will be passed in same format as tokens returned from
+  `tokenizer().getToken()`.
+
+  If array is passed, each found token is pushed to it.
+
+  Note that you are not allowed to call the parser from the
+  callback—that will corrupt its internal state.
+
+- **onComment**: If a function is passed for this option, whenever a
+  comment is encountered the function will be called with the
+  following parameters:
+
+  - `block`: `true` if the comment is a block comment, false if it
+    is a line comment.
+  - `text`: The content of the comment.
+  - `start`: Character offset of the start of the comment.
+  - `end`: Character offset of the end of the comment.
+
+  When the `locations` options is on, the `{line, column}` locations
+  of the comment’s start and end are passed as two additional
+  parameters.
+
+  If array is passed for this option, each found comment is pushed
+  to it as object in Esprima format:
+
+  ```javascript
+  {
+    "type": "Line" | "Block",
+    "value": "comment text",
+    "start": Number,
+    "end": Number,
+    // If `locations` option is on:
+    "loc": {
+      "start": {line: Number, column: Number}
+      "end": {line: Number, column: Number}
+    },
+    // If `ranges` option is on:
+    "range": [Number, Number]
+  }
+  ```
+
+  Note that you are not allowed to call the parser from the
+  callback—that will corrupt its internal state.
+
+- **ranges**: Nodes have their start and end characters offsets
+  recorded in `start` and `end` properties (directly on the node,
+  rather than the `loc` object, which holds line/column data. To also
+  add a
+  [semi-standardized](https://bugzilla.mozilla.org/show_bug.cgi?id=745678)
+  `range` property holding a `[start, end]` array with the same
+  numbers, set the `ranges` option to `true`.
+
+- **program**: It is possible to parse multiple files into a single
+  AST by passing the tree produced by parsing the first file as the
+  `program` option in subsequent parses. This will add the toplevel
+  forms of the parsed file to the "Program" (top) node of an existing
+  parse tree.
+
+- **sourceFile**: When the `locations` option is `true`, you can pass
+  this option to add a `source` attribute in every node’s `loc`
+  object. Note that the contents of this option are not examined or
+  processed in any way; you are free to use whatever format you
+  choose.
+
+- **directSourceFile**: Like `sourceFile`, but a `sourceFile` property
+  will be added (regardless of the `location` option) directly to the
+  nodes, rather than the `loc` object.
+
+- **preserveParens**: If this option is `true`, parenthesized expressions
+  are represented by (non-standard) `ParenthesizedExpression` nodes
+  that have a single `expression` property containing the expression
+  inside parentheses.
+
+**parseExpressionAt**`(input, offset, options)` will parse a single
+expression in a string, and return its AST. It will not complain if
+there is more of the string left after the expression.
+
+**tokenizer**`(input, options)` returns an object with a `getToken`
+method that can be called repeatedly to get the next token, a `{start,
+end, type, value}` object (with added `loc` property when the
+`locations` option is enabled and `range` property when the `ranges`
+option is enabled). When the token's type is `tokTypes.eof`, you
+should stop calling the method, since it will keep returning that same
+token forever.
+
+In ES6 environment, returned result can be used as any other
+protocol-compliant iterable:
+
+```javascript
+for (let token of acorn.tokenizer(str)) {
+  // iterate over the tokens
+}
+
+// transform code to array of tokens:
+var tokens = [...acorn.tokenizer(str)];
+```
+
+**tokTypes** holds an object mapping names to the token type objects
+that end up in the `type` properties of tokens.
+
+**getLineInfo**`(input, offset)` can be used to get a `{line,
+column}` object for a given program string and offset.
+
+### The `Parser` class
+
+Instances of the **`Parser`** class contain all the state and logic
+that drives a parse. It has static methods `parse`,
+`parseExpressionAt`, and `tokenizer` that match the top-level
+functions by the same name.
+
+When extending the parser with plugins, you need to call these methods
+on the extended version of the class. To extend a parser with plugins,
+you can use its static `extend` method.
+
+```javascript
+var acorn = require("acorn");
+var jsx = require("acorn-jsx");
+var JSXParser = acorn.Parser.extend(jsx());
+JSXParser.parse("foo(<bar/>)");
+```
+
+The `extend` method takes any number of plugin values, and returns a
+new `Parser` class that includes the extra parser logic provided by
+the plugins.
+
+## Command line interface
+
+The `bin/acorn` utility can be used to parse a file from the command
+line. It accepts as arguments its input file and the following
+options:
+
+- `--ecma3|--ecma5|--ecma6|--ecma7|--ecma8|--ecma9|--ecma10`: Sets the ECMAScript version
+  to parse. Default is version 9.
+
+- `--module`: Sets the parsing mode to `"module"`. Is set to `"script"` otherwise.
+
+- `--locations`: Attaches a "loc" object to each node with "start" and
+  "end" subobjects, each of which contains the one-based line and
+  zero-based column numbers in `{line, column}` form.
+
+- `--allow-hash-bang`: If the code starts with the characters #! (as
+  in a shellscript), the first line will be treated as a comment.
+
+- `--compact`: No whitespace is used in the AST output.
+
+- `--silent`: Do not output the AST, just return the exit status.
+
+- `--help`: Print the usage information and quit.
+
+The utility spits out the syntax tree as JSON data.
