+# 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');
+```

+
+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).

+// Acorn: Loose parser
+//
+// This module provides an alternative parser (`parse_dammit`) that
+// exposes that same interface as `parse`, but will try to parse
+// anything as JavaScript, repairing syntax error the best it can.
+// There are circumstances in which it will raise an error and give
+// up, but they are very rare. The resulting AST will be a mostly
+// valid JavaScript AST (as per the [Mozilla parser API][api], except
+// that:
+//
+// - Return outside functions is allowed
+//
+// - Label consistency (no conflicts, break only to existing labels)
+//   is not enforced.
+//
+// - Bogus Identifier nodes with a name of `"✖"` are inserted whenever
+//   the parser got too confused to return anything meaningful.
+//
+// [api]: https://developer.mozilla.org/en-US/docs/SpiderMonkey/Parser_API
+//
+// The expected use for this is to *first* try `acorn.parse`, and only
+// if that fails switch to `parse_dammit`. The loose parser might
+// 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
+// tangle.

+

+// token in a way that is very cheap for the parser to look up.
+
+// All token type variables start with an underscore, to make them
+// easy to recognize.
+
+// The `beforeExpr` property is used to disambiguate between regular
+// expressions and divisions. It is set on all token types that can
+// be followed by an expression (thus, a slash after them would be a
+// regular expression).
+//
+// The `startsExpr` property is used to check if the token ends a
+// `yield` expression. It is set on all token types that either can
+// directly start an expression (like a quotation mark) or can
+// continue an expression (like the body of a string).
+//
+// `isLoop` marks a keyword as starting a loop, which is important
+// to know when parsing a label, in order to allow or disallow
+// continue jumps to that label.

+
+[![Build Status](https://secure.travis-ci.org/nodeca/argparse.svg?branch=master)](http://travis-ci.org/nodeca/argparse)
+[![NPM version](https://img.shields.io/npm/v/argparse.svg)](https://www.npmjs.org/package/argparse)
+
+CLI arguments parser for node.js. Javascript port of python's
+[argparse](http://docs.python.org/dev/library/argparse.html) module
+(original version 3.2). That's a full port, except some very rare options,
+recorded in issue tracker.
+
+**NB. Difference with original.**
+
+- Method names changed to camelCase. See [generated docs](http://nodeca.github.com/argparse/).
+- Use `defaultValue` instead of `default`.
+- Use `argparse.Const.REMAINDER` instead of `argparse.REMAINDER`, and
+  similarly for constant values `OPTIONAL`, `ZERO_OR_MORE`, and `ONE_OR_MORE`
+  (aliases for `nargs` values `'?'`, `'*'`, `'+'`, respectively), and
+  `SUPPRESS`.
+
+
+Example
+=======
+
+test.js file:
+
+```javascript
+#!/usr/bin/env node
+'use strict';
+
+var ArgumentParser = require('../lib/argparse').ArgumentParser;
+var parser = new ArgumentParser({
+  version: '0.0.1',
+  addHelp:true,
+  description: 'Argparse example'
+});
+parser.addArgument(
+  [ '-f', '--foo' ],
+  {
+    help: 'foo bar'
+  }
+);
+parser.addArgument(
+  [ '-b', '--bar' ],
+  {
+    help: 'bar foo'
+  }
+);
+parser.addArgument(
+  '--baz',
+  {
+    help: 'baz bar'
+  }
+);
+var args = parser.parseArgs();
+console.dir(args);
+```
+
+Display help:
+
+```
+$ ./test.js -h
+usage: example.js [-h] [-v] [-f FOO] [-b BAR] [--baz BAZ]
+
+Argparse example
+
+Optional arguments:
+  -h, --help         Show this help message and exit.
+  -v, --version      Show program's version number and exit.
+  -f FOO, --foo FOO  foo bar
+  -b BAR, --bar BAR  bar foo
+  --baz BAZ          baz bar
+```
+
+Parse arguments:
+
+```
+$ ./test.js -f=3 --bar=4 --baz 5
+{ foo: '3', bar: '4', baz: '5' }
+```
+
+More [examples](https://github.com/nodeca/argparse/tree/master/examples).
+
+
+ArgumentParser objects
+======================
+
+```
+new ArgumentParser({parameters hash});
+```
+
+Creates a new ArgumentParser object.
+
+**Supported params:**
+
+- ```description``` - Text to display before the argument help.
+- ```epilog``` - Text to display after the argument help.
+- ```addHelp``` - Add a -h/–help option to the parser. (default: true)
+- ```argumentDefault``` - Set the global default value for arguments. (default: null)
+- ```parents``` - A list of ArgumentParser objects whose arguments should also be included.
+- ```prefixChars``` - The set of characters that prefix optional arguments. (default: ‘-‘)
+- ```formatterClass``` - A class for customizing the help output.
+- ```prog``` - The name of the program (default: `path.basename(process.argv[1])`)
+- ```usage``` - The string describing the program usage (default: generated)
+- ```conflictHandler``` - Usually unnecessary, defines strategy for resolving conflicting optionals.
+
+**Not supported yet**
+
+- ```fromfilePrefixChars``` - The set of characters that prefix files from which additional arguments should be read.
+
+
+Details in [original ArgumentParser guide](http://docs.python.org/dev/library/argparse.html#argumentparser-objects)
+
+
+addArgument() method
+====================
+
+```
+ArgumentParser.addArgument(name or flag or [name] or [flags...], {options})
+```
+
+Defines how a single command-line argument should be parsed.
+
+- ```name or flag or [name] or [flags...]``` - Either a positional name
+  (e.g., `'foo'`), a single option (e.g., `'-f'` or `'--foo'`), an array
+  of a single positional name (e.g., `['foo']`), or an array of options
+  (e.g., `['-f', '--foo']`).
+
+Options:
+
+- ```action``` - The basic type of action to be taken when this argument is encountered at the command line.
+- ```nargs```- The number of command-line arguments that should be consumed.
+- ```constant``` - A constant value required by some action and nargs selections.
+- ```defaultValue``` - The value produced if the argument is absent from the command line.
+- ```type``` - The type to which the command-line argument should be converted.
+- ```choices``` - A container of the allowable values for the argument.
+- ```required``` - Whether or not the command-line option may be omitted (optionals only).
+- ```help``` - A brief description of what the argument does.
+- ```metavar``` - A name for the argument in usage messages.
+- ```dest``` - The name of the attribute to be added to the object returned by parseArgs().
+
+Details in [original add_argument guide](http://docs.python.org/dev/library/argparse.html#the-add-argument-method)
+
+
+Action (some details)
+================
+
+ArgumentParser objects associate command-line arguments with actions.
+These actions can do just about anything with the command-line arguments associated
+with them, though most actions simply add an attribute to the object returned by
+parseArgs(). The action keyword argument specifies how the command-line arguments
+should be handled. The supported actions are:
+
+- ```store``` - Just stores the argument’s value. This is the default action.
+- ```storeConst``` - Stores value, specified by the const keyword argument.
+  (Note that the const keyword argument defaults to the rather unhelpful None.)
+  The 'storeConst' action is most commonly used with optional arguments, that
+  specify some sort of flag.
+- ```storeTrue``` and ```storeFalse``` - Stores values True and False
+  respectively. These are special cases of 'storeConst'.
+- ```append``` - Stores a list, and appends each argument value to the list.
+  This is useful to allow an option to be specified multiple times.
+- ```appendConst``` - Stores a list, and appends value, specified by the
+  const keyword argument to the list. (Note, that the const keyword argument defaults
+  is None.) The 'appendConst' action is typically used when multiple arguments need
+  to store constants to the same list.
+- ```count``` - Counts the number of times a keyword argument occurs. For example,
+  used for increasing verbosity levels.
+- ```help``` - Prints a complete help message for all the options in the current
+  parser and then exits. By default a help action is automatically added to the parser.
+  See ArgumentParser for details of how the output is created.
+- ```version``` - Prints version information and exit. Expects a `version=`
+  keyword argument in the addArgument() call.
+
+Details in [original action guide](http://docs.python.org/dev/library/argparse.html#action)
+
+
+Sub-commands
+============
+
+ArgumentParser.addSubparsers()
+
+Many programs split their functionality into a number of sub-commands, for
+example, the svn program can invoke sub-commands like `svn checkout`, `svn update`,
+and `svn commit`. Splitting up functionality this way can be a particularly good
+idea when a program performs several different functions which require different
+kinds of command-line arguments. `ArgumentParser` supports creation of such
+sub-commands with `addSubparsers()` method. The `addSubparsers()` method is
+normally called with no arguments and returns an special action object.
+This object has a single method `addParser()`, which takes a command name and
+any `ArgumentParser` constructor arguments, and returns an `ArgumentParser` object
+that can be modified as usual.
+
+Example:
+
+sub_commands.js
+```javascript
+#!/usr/bin/env node
+'use strict';
+
+var ArgumentParser = require('../lib/argparse').ArgumentParser;
+var parser = new ArgumentParser({
+  version: '0.0.1',
+  addHelp:true,
+  description: 'Argparse examples: sub-commands',
+});
+
+var subparsers = parser.addSubparsers({
+  title:'subcommands',
+  dest:"subcommand_name"
+});
+
+var bar = subparsers.addParser('c1', {addHelp:true});
+bar.addArgument(
+  [ '-f', '--foo' ],
+  {
+    action: 'store',
+    help: 'foo3 bar3'
+  }
+);
+var bar = subparsers.addParser(
+  'c2',
+  {aliases:['co'], addHelp:true}
+);
+bar.addArgument(
+  [ '-b', '--bar' ],
+  {
+    action: 'store',
+    type: 'int',
+    help: 'foo3 bar3'
+  }
+);
+
+var args = parser.parseArgs();
+console.dir(args);
+
+```

+
+## 2.0.6
+
+Version 2.0.4 adds support for React Native by clarifying in package.json that
+the browser environment does not support Node.js domains.
+Why this is necessary, we leave as an exercise for the user.
+
+## 2.0.3
+
+Version 2.0.3 fixes a bug when adjusting the capacity of the task queue.
+
+## 2.0.1-2.02
+
+Version 2.0.1 fixes a bug in the way redirects were expressed that affected the
+function of Browserify, but which Mr would tolerate.
+
+## 2.0.0
+
+Version 2 of ASAP is a full rewrite with a few salient changes.
+First, the ASAP source is CommonJS only and designed with [Browserify][] and
+[Browserify-compatible][Mr] module loaders in mind.
+
+[Browserify]: https://github.com/substack/node-browserify
+[Mr]: https://github.com/montagejs/mr
+
+The new version has been refactored in two dimensions.
+Support for Node.js and browsers have been separated, using Browserify
+redirects and ASAP has been divided into two modules.
+The "raw" layer depends on the tasks to catch thrown exceptions and unravel
+Node.js domains.
+
+The full implementation of ASAP is loadable as `require("asap")` in both Node.js
+and browsers.
+
+The raw layer that lacks exception handling overhead is loadable as
+`require("asap/raw")`.
+The interface is the same for both layers.
+
+Tasks are no longer required to be functions, but can rather be any object that
+implements `task.call()`.
+With this feature you can recycle task objects to avoid garbage collector churn
+and avoid closures in general.
+
+The implementation has been rigorously documented so that our successors can
+understand the scope of the problem that this module solves and all of its
+nuances, ensuring that the next generation of implementations know what details
+are essential.

+# ASAP
+
+[![Build Status](https://travis-ci.org/kriskowal/asap.png?branch=master)](https://travis-ci.org/kriskowal/asap)
+
+Promise and asynchronous observer libraries, as well as hand-rolled callback
+programs and libraries, often need a mechanism to postpone the execution of a
+callback until the next available event.
+(See [Designing API’s for Asynchrony][Zalgo].)
+The `asap` function executes a task **as soon as possible** but not before it
+returns, waiting only for the completion of the current event and previously
+scheduled tasks.
+
+```javascript
+asap(function () {
+    // ...
+});
+```
+
+[Zalgo]: http://blog.izs.me/post/59142742143/designing-apis-for-asynchrony
+
+This CommonJS package provides an `asap` module that exports a function that
+executes a task function *as soon as possible*.
+
+ASAP strives to schedule events to occur before yielding for IO, reflow,
+or redrawing.
+Each event receives an independent stack, with only platform code in parent
+frames and the events run in the order they are scheduled.
+
+ASAP provides a fast event queue that will execute tasks until it is
+empty before yielding to the JavaScript engine's underlying event-loop.
+When a task gets added to a previously empty event queue, ASAP schedules a flush
+event, preferring for that event to occur before the JavaScript engine has an
+opportunity to perform IO tasks or rendering, thus making the first task and
+subsequent tasks semantically indistinguishable.
+ASAP uses a variety of techniques to preserve this invariant on different
+versions of browsers and Node.js.
+
+By design, ASAP prevents input events from being handled until the task
+queue is empty.
+If the process is busy enough, this may cause incoming connection requests to be
+dropped, and may cause existing connections to inform the sender to reduce the
+transmission rate or stall.
+ASAP allows this on the theory that, if there is enough work to do, there is no
+sense in looking for trouble.
+As a consequence, ASAP can interfere with smooth animation.
+If your task should be tied to the rendering loop, consider using
+`requestAnimationFrame` instead.
+A long sequence of tasks can also effect the long running script dialog.
+If this is a problem, you may be able to use ASAP’s cousin `setImmediate` to
+break long processes into shorter intervals and periodically allow the browser
+to breathe.
+`setImmediate` will yield for IO, reflow, and repaint events.
+It also returns a handler and can be canceled.
+For a `setImmediate` shim, consider [YuzuJS setImmediate][setImmediate].
+
+[setImmediate]: https://github.com/YuzuJS/setImmediate
+
+Take care.
+ASAP can sustain infinite recursive calls without warning.
+It will not halt from a stack overflow, and it will not consume unbounded
+memory.
+This is behaviorally equivalent to an infinite loop.
+Just as with infinite loops, you can monitor a Node.js process for this behavior
+with a heart-beat signal.
+As with infinite loops, a very small amount of caution goes a long way to
+avoiding problems.
+
+```javascript
+function loop() {
+    asap(loop);
+}
+loop();
+```
+
+In browsers, if a task throws an exception, it will not interrupt the flushing
+of high-priority tasks.
+The exception will be postponed to a later, low-priority event to avoid
+slow-downs.
+In Node.js, if a task throws an exception, ASAP will resume flushing only if—and
+only after—the error is handled by `domain.on("error")` or
+`process.on("uncaughtException")`.
+
+## Raw ASAP
+
+Checking for exceptions comes at a cost.
+The package also provides an `asap/raw` module that exports the underlying
+implementation which is faster but stalls if a task throws an exception.
+This internal version of the ASAP function does not check for errors.
+If a task does throw an error, it will stall the event queue unless you manually
+call `rawAsap.requestFlush()` before throwing the error, or any time after.
+
+In Node.js, `asap/raw` also runs all tasks outside any domain.
+If you need a task to be bound to your domain, you will have to do it manually.
+
+```js
+if (process.domain) {
+    task = process.domain.bind(task);
+}
+rawAsap(task);
+```
+
+## Tasks
+
+A task may be any object that implements `call()`.
+A function will suffice, but closures tend not to be reusable and can cause
+garbage collector churn.
+Both `asap` and `rawAsap` accept task objects to give you the option of
+recycling task objects or using higher callable object abstractions.
+See the `asap` source for an illustration.
+
+
+## Compatibility
+
+ASAP is tested on Node.js v0.10 and in a broad spectrum of web browsers.
+The following charts capture the browser test results for the most recent
+release.
+The first chart shows test results for ASAP running in the main window context.
+The second chart shows test results for ASAP running in a web worker context.
+Test results are inconclusive (grey) on browsers that do not support web
+workers.
+These data are captured automatically by [Continuous
+Integration][].

+
+## Caveats
+
+When a task is added to an empty event queue, it is not always possible to
+guarantee that the task queue will begin flushing immediately after the current
+event.
+However, once the task queue begins flushing, it will not yield until the queue
+is empty, even if the queue grows while executing tasks.
+
+The following browsers allow the use of [DOM mutation observers][] to access
+the HTML [microtask queue][], and thus begin flushing ASAP's task queue
+immediately at the end of the current event loop turn, before any rendering or
+IO:
+
+[microtask queue]: http://www.whatwg.org/specs/web-apps/current-work/multipage/webappapis.html#microtask-queue
+[DOM mutation observers]: http://dom.spec.whatwg.org/#mutation-observers
+
+- Android 4–4.3
+- Chrome 26–34
+- Firefox 14–29
+- Internet Explorer 11
+- iPad Safari 6–7.1
+- iPhone Safari 7–7.1
+- Safari 6–7
+
+In the absense of mutation observers, there are a few browsers, and situations
+like web workers in some of the above browsers,  where [message channels][]
+would be a useful way to avoid falling back to timers.
+Message channels give direct access to the HTML [task queue][], so the ASAP
+task queue would flush after any already queued rendering and IO tasks, but
+without having the minimum delay imposed by timers.
+However, among these browsers, Internet Explorer 10 and Safari do not reliably
+dispatch messages, so they are not worth the trouble to implement.
+
+[message channels]: http://www.whatwg.org/specs/web-apps/current-work/multipage/web-messaging.html#message-channels
+[task queue]: http://www.whatwg.org/specs/web-apps/current-work/multipage/webappapis.html#concept-task
+
+- Internet Explorer 10
+- Safair 5.0-1
+- Opera 11-12
+
+In the absense of mutation observers, these browsers and the following browsers
+all fall back to using `setTimeout` and `setInterval` to ensure that a `flush`
+occurs.
+The implementation uses both and cancels whatever handler loses the race, since
+`setTimeout` tends to occasionally skip tasks in unisolated circumstances.
+Timers generally delay the flushing of ASAP's task queue for four milliseconds.

+- Lynx 2.8.7

+
+## Heritage
+
+ASAP has been factored out of the [Q][] asynchronous promise library.
+It originally had a naïve implementation in terms of `setTimeout`, but
+[Malte Ubl][NonBlocking] provided an insight that `postMessage` might be
+useful for creating a high-priority, no-delay event dispatch hack.
+Since then, Internet Explorer proposed and implemented `setImmediate`.
+Robert Katić began contributing to Q by measuring the performance of
+the internal implementation of `asap`, paying particular attention to
+error recovery.
+Domenic, Robert, and Kris Kowal collectively settled on the current strategy of
+unrolling the high-priority event queue internally regardless of what strategy
+we used to dispatch the potentially lower-priority flush event.
+Domenic went on to make ASAP cooperate with Node.js domains.
+
+[Q]: https://github.com/kriskowal/q
+[NonBlocking]: http://www.nonblocking.io/2011/06/windownexttick.html
+
+For further reading, Nicholas Zakas provided a thorough article on [The
+Case for setImmediate][NCZ].
+
+[NCZ]: http://www.nczonline.net/blog/2013/07/09/the-case-for-setimmediate/
+
+Ember’s RSVP promise implementation later [adopted][RSVP ASAP] the name ASAP but
+further developed the implentation.
+Particularly, The `MessagePort` implementation was abandoned due to interaction
+[problems with Mobile Internet Explorer][IE Problems] in favor of an
+implementation backed on the newer and more reliable DOM `MutationObserver`
+interface.
+These changes were back-ported into this library.
+
+[IE Problems]: https://github.com/cujojs/when/issues/197
+[RSVP ASAP]: https://github.com/tildeio/rsvp.js/blob/cddf7232546a9cf858524b75cde6f9edf72620a7/lib/rsvp/asap.js
+
+In addition, ASAP factored into `asap` and `asap/raw`, such that `asap` remained
+exception-safe, but `asap/raw` provided a tight kernel that could be used for
+tasks that guaranteed that they would not throw exceptions.
+This core is useful for promise implementations that capture thrown errors in
+rejected promises and do not need a second safety net.
+At the same time, the exception handling in `asap` was factored into separate
+implementations for Node.js and browsers, using the the [Browserify][Browser
+Config] `browser` property in `package.json` to instruct browser module loaders
+and bundlers, including [Browserify][], [Mr][], and [Mop][],  to use the
+browser-only implementation.
