+# balanced-match
+
+Match balanced string pairs, like `{` and `}` or `<b>` and `</b>`. Supports regular expressions as well!

+
+[![testling badge](https://ci.testling.com/juliangruber/balanced-match.png)](https://ci.testling.com/juliangruber/balanced-match)
+
+## Example
+
+Get the first matching pair of braces:
+
+```js
+var balanced = require('balanced-match');
+
+console.log(balanced('{', '}', 'pre{in{nested}}post'));
+console.log(balanced('{', '}', 'pre{first}between{second}post'));
+console.log(balanced(/\s+\{\s+/, /\s+\}\s+/, 'pre  {   in{nest}   }  post'));
+```
+
+The matches are:
+
+```bash
+$ node example.js
+{ start: 3, end: 14, pre: 'pre', body: 'in{nested}', post: 'post' }
+{ start: 3,
+  end: 9,
+  pre: 'pre',
+  body: 'first',
+  post: 'between{second}post' }
+{ start: 3, end: 17, pre: 'pre', body: 'in{nest}', post: 'post' }
+```
+
+## API
+
+### var m = balanced(a, b, str)
+
+For the first non-nested matching pair of `a` and `b` in `str`, return an
+object with those keys:
+
+* **start** the index of the first match of `a`
+* **end** the index of the matching `b`
+* **pre** the preamble, `a` and `b` not included
+* **body** the match, `a` and `b` not included
+* **post** the postscript, `a` and `b` not included
+
+If there's no match, `undefined` will be returned.
+
+If the `str` contains more `a` than `b` / there are unmatched pairs, the first match that was closed will be used. For example, `{{a}` will match `['{', 'a', '']` and `{a}}` will match `['', 'a', '}']`.
+
+### var r = balanced.range(a, b, str)
+
+For the first non-nested matching pair of `a` and `b` in `str`, return an
+array with indexes: `[ <a index>, <b index> ]`.
+
+If there's no match, `undefined` will be returned.
+
+If the `str` contains more `a` than `b` / there are unmatched pairs, the first match that was closed will be used. For example, `{{a}` will match `[ 1, 3 ]` and `{a}}` will match `[0, 2]`.
+
+## Installation
+
+With [npm](https://npmjs.org) do:
+
+```bash
+npm install balanced-match
+```

+bmp-js
+======
+
+A pure javascript Bmp encoder and decoder for node.js
+
+Supports all bits decoding(1,4,8,16,24,32) and encoding with 24bit.
+
+##Install
+
+	$ npm install bmp-js
+
+
+How to use?
+---
+###Decode BMP
+```js
+var bmp = require("bmp-js");
+var bmpBuffer = fs.readFileSync('bit24.bmp');
+var bmpData = bmp.decode(bmpBuffer);
+
+```
+
+`bmpData` has all properties includes:
+
+1. fileSize,reserved,offset
+
+2. headerSize,width,height,planes,bitPP,compress,rawSize,hr,vr,colors,importantColors
+
+3. palette
+
+4. data-------byte array order by ABGR ABGR ABGR,4 bytes per pixel
+
+
+###Encode RGB
+```js
+var bmp = require("bmp-js");
+//bmpData={data:Buffer,width:Number,height:Height}
+var rawData = bmp.encode(bmpData);//default no compression,write rawData to .bmp file
+
+```

+[Brace expansion](https://www.gnu.org/software/bash/manual/html_node/Brace-Expansion.html), 
+as known from sh/bash, in JavaScript.

+[![testling badge](https://ci.testling.com/juliangruber/brace-expansion.png)](https://ci.testling.com/juliangruber/brace-expansion)
+
+## Example
+
+```js
+var expand = require('brace-expansion');
+
+expand('file-{a,b,c}.jpg')
+// => ['file-a.jpg', 'file-b.jpg', 'file-c.jpg']
+
+expand('-v{,,}')
+// => ['-v', '-v', '-v']
+
+expand('file{0..2}.jpg')
+// => ['file0.jpg', 'file1.jpg', 'file2.jpg']
+
+expand('file-{a..c}.jpg')
+// => ['file-a.jpg', 'file-b.jpg', 'file-c.jpg']
+
+expand('file{2..0}.jpg')
+// => ['file2.jpg', 'file1.jpg', 'file0.jpg']
+
+expand('file{0..4..2}.jpg')
+// => ['file0.jpg', 'file2.jpg', 'file4.jpg']
+
+expand('file-{a..e..2}.jpg')
+// => ['file-a.jpg', 'file-c.jpg', 'file-e.jpg']
+
+expand('file{00..10..5}.jpg')
+// => ['file00.jpg', 'file05.jpg', 'file10.jpg']
+
+expand('{{A..C},{a..c}}')
+// => ['A', 'B', 'C', 'a', 'b', 'c']
+
+expand('ppp{,config,oe{,conf}}')
+// => ['ppp', 'pppconfig', 'pppoe', 'pppoeconf']
+```
+
+## API
+
+```js
+var expand = require('brace-expansion');
+```
+
+### var expanded = expand(str)
+
+Return an array of all possible and valid expansions of `str`. If none are
+found, `[str]` is returned.
+
+Valid expansions are:
+
+```js
+/^(.*,)+(.+)?$/
+// {a,b,...}
+```
+
+A comma separated list of options, like `{a,b}` or `{a,{b,c}}` or `{,a,}`.
+
+```js
+/^-?\d+\.\.-?\d+(\.\.-?\d+)?$/
+// {x..y[..incr]}
+```
+
+A numeric sequence from `x` to `y` inclusive, with optional increment.
+If `x` or `y` start with a leading `0`, all the numbers will be padded
+to have equal length. Negative numbers and backwards iteration work too.
+
+```js
+/^-?\d+\.\.-?\d+(\.\.-?\d+)?$/
+// {x..y[..incr]}
+```
+
+An alphabetic sequence from `x` to `y` inclusive, with optional increment.
+`x` and `y` must be exactly one character, and if given, `incr` must be a
+number.
+
+For compatibility reasons, the string `${` is not eligible for brace expansion.
+
+## Installation
+

+
+## Usage
+
+By popular demand, `colors` now ships with two types of usages!
+
+The super nifty way
+
+```js
+var colors = require('colors');
+
+console.log('hello'.green); // outputs green text
+console.log('i like cake and pies'.underline.red) // outputs red underlined text
+console.log('inverse the color'.inverse); // inverses the color
+console.log('OMG Rainbows!'.rainbow); // rainbow
+console.log('Run the trap'.trap); // Drops the bass
+
+```
+
+or a slightly less nifty way which doesn't extend `String.prototype`
+
+```js
+var colors = require('colors/safe');
+
+console.log(colors.green('hello')); // outputs green text
+console.log(colors.red.underline('i like cake and pies')) // outputs red underlined text
+console.log(colors.inverse('inverse the color')); // inverses the color
+console.log(colors.rainbow('OMG Rainbows!')); // rainbow
+console.log(colors.trap('Run the trap')); // Drops the bass
+
+```
+
+I prefer the first way. Some people seem to be afraid of extending `String.prototype` and prefer the second way. 
+
+If you are writing good code you will never have an issue with the first approach. If you really don't want to touch `String.prototype`, the second usage will not touch `String` native object.
+
+## Enabling/Disabling Colors
+
+The package will auto-detect whether your terminal can use colors and enable/disable accordingly. When colors are disabled, the color functions do nothing. You can override this with a command-line flag:
+
+```bash
+node myapp.js --no-color
+node myapp.js --color=false
+
+node myapp.js --color
+node myapp.js --color=true
+node myapp.js --color=always
+
+FORCE_COLOR=1 node myapp.js
+```
+
+Or in code:
+
+```javascript
+var colors = require('colors');
+colors.enable();
+colors.disable();
+```
+
+## Console.log [string substitution](http://nodejs.org/docs/latest/api/console.html#console_console_log_data)
+
+```js
+var name = 'Marak';
+console.log(colors.green('Hello %s'), name);
+// outputs -> 'Hello Marak'
+```
+
+## Custom themes
+
+### Using standard API
+
+```js
+
+var colors = require('colors');
+
+colors.setTheme({
+  silly: 'rainbow',
+  input: 'grey',
+  verbose: 'cyan',
+  prompt: 'grey',
+  info: 'green',
+  data: 'grey',
+  help: 'cyan',
+  warn: 'yellow',
+  debug: 'blue',
+  error: 'red'
+});
+
+// outputs red text
+console.log("this is an error".error);
+

+
+example
+=======
+
+``` js
+var concatMap = require('concat-map');
+var xs = [ 1, 2, 3, 4, 5, 6 ];
+var ys = concatMap(xs, function (x) {
+    return x % 2 ? [ x - 0.1, x, x + 0.1 ] : [];

+```
+[ 0.9, 1, 1.1, 2.9, 3, 3.1, 4.9, 5, 5.1 ]
+```
+
+methods
+=======
+
+``` js
+var concatMap = require('concat-map')
+```
+
+concatMap(xs, fn)
+-----------------
+
+Return an array of concatenated elements by calling `fn(x, i)` for each element
+`x` and each index `i` in the array `xs`.
+
+When `fn(x, i)` returns an array, its result will be concatenated with the
+result array. If `fn(x, i)` returns anything else, that value will be pushed
+onto the end of the result array.
+
+install
+=======
+
+With [npm](http://npmjs.org) do:
+
+```
+npm install concat-map
