+# 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 module that implements `window.atob` and `window.btoa` according to the [WHATWG spec](https://html.spec.whatwg.org/multipage/webappapis.html#atob). The code is originally 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 (using browserify or webpack)
+
+Install with `npm`:
+
+```sh
+npm install abab
+```
+
+## API
+
+### `btoa` (base64 encode)
+
+```js
+const btoa = require('abab').btoa;
+btoa('Hello, world!'); // 'SGVsbG8sIHdvcmxkIQ=='
+```
+
+### `atob` (base64 decode)
+
+```js 
+const atob = require('abab').atob;
+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
+var atob = require('abab/lib/atob');
+var btoa = require('abab/lib/btoa');
+```
+
+-----
+
+### Checklists
+
+If you're **submitting a PR** or **deploying to npm**, please use the [checklists in CONTRIBUTING.md](https://github.com/jsdom/abab/blob/master/CONTRIBUTING.md#checklists)
+
+### Remembering `atob` vs. `btoa`
+
+Here's a mnemonic that might be useful: if you have a plain string and want to base64 encode it, then decode it, `btoa` is what you run before (**b**efore - **b**toa), and `atob` is what you run after (**a**fter - **a**tob).

+A tiny, fast JavaScript parser, written completely in JavaScript.
+
+## Community
+
+Acorn is open source software released under an
+[MIT license](https://github.com/ternjs/acorn/blob/master/LICENSE).
+
+You are welcome to
+[report bugs](https://github.com/ternjs/acorn/issues) or create pull
+requests on [github](https://github.com/ternjs/acorn). For questions
+and discussion, please use the
+[Tern discussion forum](https://discuss.ternjs.net).
+
+## Installation
+
+The easiest way to install acorn is with [`npm`][npm].
+
+[npm]: https://www.npmjs.com/
+
+```sh
+npm install acorn
+```
+
+Alternately, download the source.
+
+```sh
+git clone https://github.com/ternjs/acorn.git
+```
+
+## Components
+
+When run in a CommonJS (node.js) or AMD environment, exported values
+appear in the interfaces exposed by the individual files, as usual.
+When loaded in the browser (Acorn works in any JS-enabled browser more
+recent than IE5) without any kind of module management, a single
+global object `acorn` will be defined, and all the exported properties
+will be added to that.
+
+### Main parser
+
+This is implemented in `dist/acorn.js`, and is what you get when you
+`require("acorn")` in node.js.
+
+**parse**`(input, options)` is used to parse a JavaScript program.
+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][estree].
+
+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 character offset at which the
+error occurred,  and a `loc`  object that contains a  `{line, column}`
+object referring to that same position.
+
+[estree]: https://github.com/estree/estree
+
+- **ecmaVersion**: Indicates the ECMAScript version to parse. Must be
+  either 3, 5, or 6. This influences support for strict mode, the set
+  of reserved words, and support for new syntax features. Default is 5.
+
+- **sourceType**: Indicate the mode the code should be parsed in. Can be
+  either `"script"` or `"module"`.
+
+- **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.
+
+- **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][range] `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 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.
+
+[range]: https://bugzilla.mozilla.org/show_bug.cgi?id=745678
+
+**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.
+
+**getLineInfo**`(input, offset)` can be used to get a `{line,
+column}` object for a given program string and character offset.
+
+**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.
+
+#### Note on using with [Escodegen][escodegen]
+
+Escodegen supports generating comments from AST, attached in
+Esprima-specific format. In order to simulate same format in
+Acorn, consider following example:
+
+```javascript
+var comments = [], tokens = [];
+
+var ast = acorn.parse('var x = 42; // answer', {
+	// collect ranges for each node
+	ranges: true,
+	// collect comments in Esprima's format
+	onComment: comments,
+	// collect token ranges
+	onToken: tokens
+});
+
+// attach comments using collected information
+escodegen.attachComments(ast, comments, tokens);
+
+// generate code
+console.log(escodegen.generate(ast, {comment: true}));
+// > 'var x = 42;    // answer'
+```
+
+[escodegen]: https://github.com/estools/escodegen
+
+### dist/acorn_loose.js ###
+
+This file implements an error-tolerant parser. It exposes a single
+function. The loose parser is accessible in node.js via `require("acorn/dist/acorn_loose")`.
+
+**parse_dammit**`(input, options)` takes the same arguments and
+returns the same syntax tree as the `parse` function in `acorn.js`,
+but never raises an error, and will do its best to parse syntactically
+invalid code in as meaningful a way as it can. It'll insert identifier
+nodes with name `"✖"` as placeholders in places where it can't make
+sense of the input. Depends on `acorn.js`, because it uses the same
+tokenizer.
+
+### dist/walk.js ###
+
+Implements an abstract syntax tree walker. Will store its interface in
+`acorn.walk` when loaded without a module system.
+
+**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][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.)
+
+**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 callbacks in the `state` parameter.
+
+**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`.
+
+**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).
+
+## 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`: Sets the ECMAScript version to parse. Default is
+  version 5.
+
+- `--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.
+
+## Build system
+
+Acorn is written in ECMAScript 6, as a set of small modules, in the
+project's `src` directory, and compiled down to bigger ECMAScript 3
+files in `dist` using [Browserify](http://browserify.org) and
+[Babel](http://babeljs.io/). If you are already using Babel, you can
+consider including the modules directly.
+
+The command-line test runner (`npm test`) uses the ES6 modules. The
+browser-based test page (`test/index.html`) uses the compiled modules.
+The `bin/build-acorn.js` script builds the latter from the former.
+
+If you are working on Acorn, you'll probably want to try the code out
+directly, without an intermediate build step. In your scripts, you can
+register the Babel require shim like this:
+
+    require("babel-core/register")
+
+That will allow you to directly `require` the ES6 modules.
+
+## Plugins
+
+Acorn is designed support allow plugins which, within reasonable
+bounds, redefine the way the parser works. Plugins can add new token
+types and new tokenizer contexts (if necessary), and extend methods in
+the parser object. This is not a clean, elegant API—using it requires
+an understanding of Acorn's internals, and plugins are likely to break
+whenever those internals are significantly changed. But still, it is
+_possible_, in this way, to create parsers for JavaScript dialects
+without forking all of Acorn. And in principle it is even possible to
+combine such plugins, so that if you have, for example, a plugin for
+parsing types and a plugin for parsing JSX-style XML literals, you
+could load them both and parse code with both JSX tags and types.
+
+A plugin should register itself by adding a property to
+`acorn.plugins`, which holds a function. Calling `acorn.parse`, a
+`plugins` option can be passed, holding an object mapping plugin names
+to configuration values (or just `true` for plugins that don't take
+options). After the parser object has been created, the initialization
+functions for the chosen plugins are called with `(parser,
+configValue)` arguments. They are expected to use the `parser.extend`
+method to extend parser methods. For example, the `readToken` method
+could be extended like this:
+
+```javascript
+parser.extend("readToken", function(nextMethod) {
+  return function(code) {
+    console.log("Reading a token!")
+    return nextMethod.call(this, code)
+  }
+})
+```
+
+The `nextMethod` argument passed to `extend`'s second argument is the
+previous value of this method, and should usually be called through to
+whenever the extended method does not handle the call itself.
+
+Similarly, the loose parser allows plugins to register themselves via
+`acorn.pluginsLoose`.  The extension mechanism is the same as for the
+normal parser:
+
+```javascript
+looseParser.extend("readToken", function(nextMethod) {
+  return function() {
+    console.log("Reading a token in the loose parser!")
+    return nextMethod.call(this)
+  }
+})
+```
+
+There is a proof-of-concept JSX plugin in the [`acorn-jsx`](https://github.com/RReverser/acorn-jsx) project.

+//
+// - Return outside functions is allowed

+// - Label consistency (no conflicts, break only to existing labels)

+// parse badly indented code incorrectly, so **don't** use it as
+// your default parser.
+//
+// Quite a lot of acorn.js is duplicated here. The alternative was to
+// add a *lot* of extra cruft to that file, making it less readable
+// and slower. Copying and editing the code allowed me to make
+// invasive changes and simplifications without creating a complicated

+# align-text [![NPM version](https://badge.fury.io/js/align-text.svg)](http://badge.fury.io/js/align-text)  [![Build Status](https://travis-ci.org/jonschlinkert/align-text.svg)](https://travis-ci.org/jonschlinkert/align-text)
+
+> Align the text in a string.
+
+**Examples**
+
+Align text values in an array:
+
+```js
+align([1, 2, 3, 100]);
+//=> ['  1', '  2', '  3', '100']
+```
+
+Or [do stuff like this](./example.js):
+
+[![screen shot 2015-06-09 at 2 08 34 am](https://cloud.githubusercontent.com/assets/383994/8051597/7b716fbc-0e4c-11e5-9aef-4493fd22db58.png)](./example.js)
+
+Visit [the example](./example.js) to see how this works.
+
+## Install
+
+Install with [npm](https://www.npmjs.com/)
+
+```sh
+$ npm i align-text --save
+```
+
+## Usage
+
+```js
+var align = require('align-text');
+align(text, callback_function_or_integer);
+```
+
+**Params**
+
+* `text` can be a **string or array**. If a string is passed, a string will be returned. If an array is passed, an array will be returned.
+* `callback|integer`: if an integer, the text will be indented by that amount. If a function, it must return an integer representing the amount of leading indentation to use as `align` loops over each line.
+
+**Example**
+
+```js
+align(text, 4);
+```
+
+Would align:
+
+```
+abc
+abc
+abc
+```
+
+To:
+
+```
+    abc
+    abc
+    abc
+```
+
+## callback
+
+### params
+
+The callback is used to determine the indentation of each line and gets the following params:
+
+* `len` the length of the "current" line
+* `longest` the length of the longest line
+* `line` the current line (string) being aligned
+* `lines` the array of all lines
+
+### return
+
+The callback may return:
+
+* an integer that represents the number of spaces to use for padding,
+* or an object with the following properties:
+  - `indent`: **{Number}** the amount of indentation to use. Default is `0` when an object is returned.
+  - `character`: **{String}** the character to use for indentation. Default is `''` (empty string) when an object is returned.
+  - `prefix`: **{String}** leading characters to use at the beginning of each line. `''` (empty string) when an object is returned.
+
+**Integer example:**
+
+```js
+// calculate half the difference between the length
+// of the current line and the longest line
+function centerAlign(len, longest, line, lines) {
+  return Math.floor((longest - len) / 2);
+}
+```
+
+**Object example:**
+
+```js
+function centerAlign(len, longest, line, lines) {
+  return {
+    character: '\t',
+    indent: Math.floor((longest - len) / 2),
+    prefix: '~ ',
+  }
+}
+```
+
+## Usage examples
+
+### Center align
+
+Using the `centerAlign` function from above:
+
+```js
+align(text, centerAlign);
+```
+
+Would align this text:
+
+```js
+Lorem ipsum dolor sit amet
+consectetur adipiscin
+elit, sed do eiusmod tempor incididun
+ut labore et dolor
+magna aliqua. Ut enim ad mini
+veniam, quis
+```
+
+Resulting in this:
+
+```
+     Lorem ipsum dolor sit amet,
+        consectetur adipiscing
+elit, sed do eiusmod tempor incididunt
+         ut labore et dolore
+    magna aliqua. Ut enim ad minim
+             veniam, quis
+```
+
+**Customize**
+
+If you wanted to add more padding on the left, just pass the number in the callback.
+
+For example, to add 4 spaces before every line:
+
+```js
+function centerAlign(len, longest, line, lines) {
+  return 4 + Math.floor((longest - len) / 2);
+}
+```
+
+Would result in:
+
+```
+         Lorem ipsum dolor sit amet,
+            consectetur adipiscing
+    elit, sed do eiusmod tempor incididunt
+             ut labore et dolore
+        magna aliqua. Ut enim ad minim
+                 veniam, quis
+```
+
+### Bullets
+
+```js
+align(text, function (len, max, line, lines) {
+  return {prefix: ' - '};
+});
+```
+
+Would return:
+
+```
+- Lorem ipsum dolor sit amet,
+- consectetur adipiscing
+- elit, sed do eiusmod tempor incididunt
+- ut labore et dolore
+- magna aliqua. Ut enim ad minim
+- veniam, quis
+```
+
+### Different indent character
+
+```js
+align(text, function (len, max, line, lines) {
+  return { 
+    indent: Math.floor((max - len) / 2), 
+    character: '~', 
+  };
+});
+```
+
+Would return
+
+```
+~~~~~Lorem ipsum dolor sit amet,
+~~~~~~~~consectetur adipiscing
+elit, sed do eiusmod tempor incididunt
+~~~~~~~~~ut labore et dolore
+~~~~magna aliqua. Ut enim ad minim
+~~~~~~~~~~~~~veniam, quis
+```

+
+> [ANSI escape codes](http://en.wikipedia.org/wiki/ANSI_escape_code#Colors_and_Styles) for styling strings in the terminal
+
+You probably want the higher-level [chalk](https://github.com/chalk/chalk) module for styling your strings.
+
+![](screenshot.png)
+
+
+## Install
+
+```
+$ npm install --save ansi-styles
+```
+
+
+## Usage
+
+```js
+var ansi = require('ansi-styles');
+
+console.log(ansi.green.open + 'Hello world!' + ansi.green.close);
+```
+
+
+## API
+
+Each style has an `open` and `close` property.
+
+
+## Styles
+
+### Modifiers
+
+- `reset`
+- `bold`
+- `dim`
+- `italic` *(not widely supported)*
+- `underline`
+- `inverse`
+- `hidden`
+- `strikethrough` *(not widely supported)*
+
+### Colors
+
+- `black`
+- `red`
+- `green`
+- `yellow`
+- `blue`
+- `magenta`
+- `cyan`
+- `white`
+- `gray`
+
+### Background colors
+
+- `bgBlack`
+- `bgRed`
+- `bgGreen`
+- `bgYellow`
+- `bgBlue`
+- `bgMagenta`
+- `bgCyan`
+- `bgWhite`
+
+
+## Advanced usage
+
+By default you get a map of styles, but the styles are also available as groups. They are non-enumerable so they don't show up unless you access them explicitly. This makes it easier to expose only a subset in a higher-level module.
+
+- `ansi.modifiers`
+- `ansi.colors`
+- `ansi.bgColors`
+
+
+###### Example
+
+```js
+console.log(ansi.colors.green.open);
+```
