> Regular expression for matching [ANSI escape codes](http://en.wikipedia.org/wiki/ANSI_escape_code)
## Install
```
$ npm install --save ansi-regex
```
## Usage
```js
const ansiRegex = require('ansi-regex');
ansiRegex().test('\u001b[4mcake\u001b[0m');
//=> true
ansiRegex().test('cake');
//=> false
'\u001b[4mcake\u001b[0m'.match(ansiRegex());
//=> ['\u001b[4m', '\u001b[0m']
```
## FAQ
### Why do you test for codes not in the ECMA 48 standard?
Some of the codes we run as a test are codes that we acquired finding various lists of non-standard or manufacturer specific codes. If I recall correctly, we test for both standard and non-standard codes, as most of them follow the same or similar format and can be safely matched in strings without the risk of removing actual string content. There are a few non-standard control codes that do not follow the traditional format (i.e. they end in numbers) thus forcing us to exclude them from the test because we cannot reliably match them.
On the historical side, those ECMA standards were established in the early 90's whereas the VT100, for example, was designed in the mid/late 70's. At that point in time, control codes were still pretty ungoverned and engineers used them for a multitude of things, namely to activate hardware ports that may have been proprietary. Somewhere else you see a similar 'anarchy' of codes is in the x86 architecture for processors; there are a ton of "interrupts" that can mean different things on certain brands of processors, most of which have been phased out.

# ansi-styles [![Build Status](https://travis-ci.org/chalk/ansi-styles.svg?branch=master)](https://travis-ci.org/chalk/ansi-styles)
> [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);
```

node-asn1 is a library for encoding and decoding ASN.1 datatypes in pure JS.
Currently BER encoding is supported; at some point I'll likely have to do DER.
## Usage
Mostly, if you're *actually* needing to read and write ASN.1, you probably don't
need this readme to explain what and why. If you have no idea what ASN.1 is,
see this: ftp://ftp.rsa.com/pub/pkcs/ascii/layman.asc
The source is pretty much self-explanatory, and has read/write methods for the
common types out there.
### Decoding
The following reads an ASN.1 sequence with a boolean.
var Ber = require('asn1').Ber;
var reader = new Ber.Reader(new Buffer([0x30, 0x03, 0x01, 0x01, 0xff]));
reader.readSequence();
console.log('Sequence len: ' + reader.length);
if (reader.peek() === Ber.Boolean)
console.log(reader.readBoolean());
### Encoding
The following generates the same payload as above.
var Ber = require('asn1').Ber;
var writer = new Ber.Writer();
writer.startSequence();
writer.writeBoolean(true);
writer.endSequence();
console.log(writer.buffer);
## Installation
npm install asn1

# assert-plus Changelog
## 0.2.0
- Fix `assert.object(null)` so it throws
- Fix optional/arrayOf exports for non-type-of asserts
- Add optiona/arrayOf exports for Stream/Date/Regex/uuid
- Add basic unit test coverage
# assert-plus
This library is a super small wrapper over node's assert module that has two
things: (1) the ability to disable assertions with the environment variable
NODE\_NDEBUG, and (2) some API wrappers for argument testing. Like
`assert.string(myArg, 'myArg')`. As a simple example, most of my code looks
like this:
```javascript
var assert = require('assert-plus');
function fooAccount(options, callback) {
assert.object(options, 'options');
assert.number(options.id, 'options.id');
assert.bool(options.isManager, 'options.isManager');
assert.string(options.name, 'options.name');
assert.arrayOfString(options.email, 'options.email');
assert.func(callback, 'callback');
// Do stuff
callback(null, {});
}
```
# API
All methods that *aren't* part of node's core assert API are simply assumed to
take an argument, and then a string 'name' that's not a message; `AssertionError`
will be thrown if the assertion fails with a message like:
AssertionError: foo (string) is required
at test (/home/mark/work/foo/foo.js:3:9)
at Object.<anonymous> (/home/mark/work/foo/foo.js:15:1)
at Module._compile (module.js:446:26)
at Object..js (module.js:464:10)
at Module.load (module.js:353:31)
at Function._load (module.js:311:12)
at Array.0 (module.js:484:10)
at EventEmitter._tickCallback (node.js:190:38)
from:
```javascript
function test(foo) {
assert.string(foo, 'foo');
}
```
There you go. You can check that arrays are of a homogeneous type with `Arrayof$Type`:
```javascript
function test(foo) {
assert.arrayOfString(foo, 'foo');
}
```
You can assert IFF an argument is not `undefined` (i.e., an optional arg):
```javascript
assert.optionalString(foo, 'foo');
```
Lastly, you can opt-out of assertion checking altogether by setting the
environment variable `NODE_NDEBUG=1`. This is pseudo-useful if you have
lots of assertions, and don't want to pay `typeof ()` taxes to v8 in
production. Be advised: The standard functions re-exported from `assert` are
also disabled in assert-plus if NDEBUG is specified. Using them directly from
the `assert` module avoids this behavior.
The complete list of APIs is:
* assert.array
* assert.bool
* assert.buffer
* assert.func
* assert.number
* assert.object
* assert.string
* assert.stream
* assert.date
* assert.regex
* assert.uuid
* assert.arrayOfArray
* assert.arrayOfBool
* assert.arrayOfBuffer
* assert.arrayOfFunc
* assert.arrayOfNumber
* assert.arrayOfObject
* assert.arrayOfString
* assert.arrayOfStream
* assert.arrayOfDate
* assert.arrayOfUuid
* assert.optionalArray
* assert.optionalBool
* assert.optionalBuffer
* assert.optionalFunc
* assert.optionalNumber
* assert.optionalObject
* assert.optionalString
* assert.optionalStream
* assert.optionalDate
* assert.optionalUuid
* assert.optionalArrayOfArray
* assert.optionalArrayOfBool
* assert.optionalArrayOfBuffer
* assert.optionalArrayOfFunc
* assert.optionalArrayOfNumber
* assert.optionalArrayOfObject
* assert.optionalArrayOfString
* assert.optionalArrayOfStream
* assert.optionalArrayOfDate
* assert.optionalArrayOfUuid
* assert.AssertionError
* assert.fail
* assert.ok
* assert.equal
* assert.notEqual
* assert.deepEqual
* assert.notDeepEqual
* assert.strictEqual
* assert.notStrictEqual
* assert.throws

Async is a utility module which provides straight-forward, powerful functions for working with [asynchronous JavaScript](http://caolan.github.io/async/global.html). Although originally designed for use with [Node.js](https://nodejs.org/) and installable via `npm install --save async`, it can also be used directly in the browser.

/**
* Determines the best order for running the {@link AsyncFunction}s in `tasks`, based on

* being completed first, and each function is run as soon as its requirements
* are satisfied.
*
* If any of the {@link AsyncFunction}s pass an error to their callback, the `auto` sequence
* will stop. Further tasks will not execute (so any other functions depending
* on it will not run), and the main `callback` is immediately called with the
* error.
*
* {@link AsyncFunction}s also receive an object containing the results of functions which
* have completed so far as the first argument, if they have dependencies. If a
* task function has no dependencies, it will only be passed a callback.
*
* @name auto
* @static
* @memberOf module:ControlFlow
* @method
* @category Control Flow
* @param {Object} tasks - An object. Each of its properties is either a
* function or an array of requirements, with the {@link AsyncFunction} itself the last item
* in the array. The object's key of a property serves as the name of the task
* defined by that property, i.e. can be used when specifying requirements for
* other tasks. The function receives one or two arguments:
* * a `results` object, containing the results of the previously executed
* functions, only passed if the task has any dependencies,
* * a `callback(err, result)` function, which must be called when finished,
* passing an `error` (which can be `null`) and the result of the function's
* execution.
* @param {number} [concurrency=Infinity] - An optional `integer` for
* determining the maximum number of tasks that can be run in parallel. By
* default, as many as possible.
* @param {Function} [callback] - An optional callback which is called when all
* the tasks have been completed. It receives the `err` argument if any `tasks`
* pass an error to their callback. Results are always returned; however, if an
* error occurs, no further `tasks` will be performed, and the results object
* will only contain partial results. Invoked with (err, results).
* @returns undefined
* @example
*
* async.auto({
* // this function will just be passed a callback
* readData: async.apply(fs.readFile, 'data.txt', 'utf-8'),

* depends on. This can provide even more readable task graphs which can be
* easier to maintain.
*
* If a final callback is specified, the task results are similarly injected,
* specified as named parameters after the initial error parameter.
*
* The autoInject function is purely syntactic sugar and its semantics are
* otherwise equivalent to [async.auto]{@link module:ControlFlow.auto}.
*
* @name autoInject
* @static
* @memberOf module:ControlFlow
* @method
* @see [async.auto]{@link module:ControlFlow.auto}
* @category Control Flow
* @param {Object} tasks - An object, each of whose properties is an {@link AsyncFunction} of
* the form 'func([dependencies...], callback). The object's key of a property
* serves as the name of the task defined by that property, i.e. can be used
* when specifying requirements for other tasks.
* * The `callback` parameter is a `callback(err, result)` which must be called
* when finished, passing an `error` (which can be `null`) and the result of
* the function's execution. The remaining parameters name other tasks on
* which the task is dependent, and the results from those tasks are the
* arguments of those parameters.
* @param {Function} [callback] - An optional callback which is called when all
* the tasks have been completed. It receives the `err` argument if any `tasks`
* pass an error to their callback, and a `results` object with any completed
* task results, similar to `auto`.
* @example
*
* // The example from `auto` can be rewritten as follows:
* async.autoInject({
* get_data: function(callback) {
* // async code to get some data
* callback(null, 'data', 'converted to array');
* },
* make_folder: function(callback) {
* // async code to create a directory to store a file in
* // this is run at the same time as getting the data
* callback(null, 'folder');
* },
* write_file: function(get_data, make_folder, callback) {
* // once there is some data and the directory exists,
* // write the data to a file in the directory
* callback(null, 'filename');
* },
* email_link: function(write_file, callback) {
* // once the file is written let's email a link to it...
* // write_file contains the filename returned by write_file.
* callback(null, {'file':write_file, 'email':'user@example.com'});
* }
* }, function(err, results) {
* console.log('err = ', err);
* console.log('email_link = ', results.email_link);
* });
*
* // If you are using a JS minifier that mangles parameter names, `autoInject`
* // will not work with plain functions, since the parameter names will be
* // collapsed to a single letter identifier. To work around this, you can
* // explicitly specify the names of the parameters your task function needs
* // in an array, similar to Angular.js dependency injection.
*
* // This still has an advantage over plain `auto`, since the results a task
* // depends on are still spread into arguments.
* async.autoInject({
* //...
* write_file: ['get_data', 'make_folder', function(get_data, make_folder, callback) {
* callback(null, 'filename');
* }],
* email_link: ['write_file', function(write_file, callback) {
* callback(null, {'file':write_file, 'email':'user@example.com'});
* }]
* //...
* }, function(err, results) {
* console.log('err = ', err);
