+# balanced-match
+
+Match balanced string pairs, like `{` and `}` or `<b>` and `</b>`. Supports regular expressions as well!
+
+[![build status](https://secure.travis-ci.org/juliangruber/balanced-match.svg)](http://travis-ci.org/juliangruber/balanced-match)
+[![downloads](https://img.shields.io/npm/dm/balanced-match.svg)](https://www.npmjs.org/package/balanced-match)
+
+[![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]`.
+

+# postcss-reporter
+[![Build Status](https://travis-ci.org/postcss/postcss-reporter.svg?branch=master)](https://travis-ci.org/postcss/postcss-reporter)
+[![AppVeyor Build Status](https://img.shields.io/appveyor/ci/davidtheclark/postcss-reporter/master.svg?label=windows%20build)](https://ci.appveyor.com/project/davidtheclark/postcss-reporter)
+
+A PostCSS plugin to `console.log()` the messages (warnings, etc.) registered by other PostCSS plugins.
+
+## Purpose
+
+As of PostCSS 4.1, a single PostCSS process can accumulate messages from all of the plugins it uses.
+Most of these messages are [warnings](https://github.com/postcss/postcss/blob/master/docs/guidelines/plugin.md#32-use-resultwarn-for-warnings).
+Presumably, plugin authors want you to see those messages.
+So this plugin exists to read the accumulated messages (or messages from only the plugins you've specified), format them, and print them to the console.
+
+By default, the messages are formatted for human legibility and sorted according to the line/column positions attached to the messages. But another formatting function can be passed in with an option, and sorting can be turned of with an option.
+
+*By default, only warnings are logged*. If you would like to see more messages, you can change the `filter` function.
+
+## Example Output
+
+![Example](example.png?raw=true)
+
+## Installation
+
+```
+npm install postcss-reporter
+```
+
+Version 1.0.0+ is compatible with PostCSS 5+. (Earlier versions are compatible with PostCSS 4.)
+
+## Usage
+
+Add it to your plugin list *after any plugins whose messages you want to log*, and optionally pass it an object of options.
+
+For example, using [gulp-postcss](https://github.com/postcss/gulp-postcss):
+
+```js
+gulp.task('css', function() {
+  return gulp.src('./src/*.css')
+    .pipe(postcss([
+      bemLinter(),
+      customProperties(),
+      calc(),
+      rejectAllColors(),
+      reporter(myOptions) // <------ ding
+    ]))
+    .pipe(gulp.dest('./dist'));
+});
+```
+
+## Options
+
+**clearReportedMessages** (boolean, default = `false`)
+
+If true, the plugin will clear the result's messages after it logs them. This prevents other plugins, or the whatever runner you use, from logging the same information again and causing confusion.
+
+**formatter** (function, default = the default formatter)
+
+By default, this reporter will format the messages for human legibility in the console.
+To use another formatter, pass a function that
+
+  - accepts an object containing a `messages` array and a `source` string
+  - returns the string to report
+
+For example, you could write a formatter like this:
+
+```js
+reporter({
+  formatter: function(input) {
+    return input.source + ' produced ' + input.messages.length + ' messages';
+  }
+})
+```
+
+**plugins** (array of strings, default = `[]`)
+
+If `plugins` is empty (as it is by default), the reporter will log messages from every PostCSS plugin.
+
+There are 2 ways to limit output:
+
+- **Whitelist:** Provide an array of the plugins whose messages you would like to show.
+  For example, `{ plugins: ['postcss-bem-linter'] }` will only log messages from the `postcss-bem-linter` plugin.
+- **Blacklist:** Prefix all plugins in the array with `!` to specify only those plugins whose messages you would like to hide.
+  (All other plugins will be shown.)
+  For example, `{ plugins: ['!postcss-bem-linter'] }` will never log messages from the `postcss-bem-linter` plugin; but will log messages from every other plugin.
+
+**filter** (function)
+
+Provide a filter function. It receives the message object and returns a truthy or falsy value, indicating whether that particular message should be reported or not.
+
+By default, only messages with `type: "warning"` warnings are logged. (These are the messages produced when the plugin author uses PostCSS's `warn()` function.)
+
+For example, `function(message) { return true }` will only every message, regardless of the plugin or whether it's a warning or not.
+
+**clearAllMessages** (boolean, default = `false`)
+
+If `true`, not pass any messages into other plugins, or the whatever runner you use, for logging.
+
+**throwError** (boolean, default = `false`)
+
+If `true`, after the plugin logs your messages it will throw an error if it found any warnings.
+
+**sortByPosition** (boolean, default = `true`)
+
+If `false`, messages will not be sorted by line/column position.
+
+**positionless** (`"first"|"last"|"any"`, default = `"first"`)
+
+By default, messages without line/column positions will be grouped at the beginning of the output.
+To put them at the end, instead, use `"last"`.
+To not bother sorting these, use `"any"`.
+
+**noIcon** (boolean, default = `false`)
+
+If `true`, no exclamatory triangle icons will be printed next to warnings.
+
+**noPlugin** (boolean, default = `false`)
+
+If `true`, plugin names will not be printed in brackets after messages.
+
+## How to get output without colors
+
+If you would like no colors in the console output, simply pass `--no-colors` when you invoke whatever command runs this plugin. (This works because of [chalk](https://github.com/sindresorhus/chalk).)
+
+## Standalone formatter
+
+You can also use this module's formatter as a library, with following API:
+
+```js
+var formatter = require('postcss-reporter/lib/formatter');
+var myFormatter = formatter(myOptions);
+// to use defaults, just pass no options: `formatter()`
+var warningLog = myFormatter({
+  messages: someMessages,
+  source: someSource
+});
+console.log(warningLog);
+```
+
+These are the formatter's options:
+
+- sortByPosition (boolean, default = `true`)
+- noIcon (boolean, default = `false`) - Do not print any warning exclamatory triangle icons
+- noPlugin (boolean, default = `false`) - Do not print plugin names

+# reduce-css-calc [![Build Status](https://travis-ci.org/MoOx/reduce-css-calc.png)](https://travis-ci.org/MoOx/reduce-css-calc)
+
+> Reduce CSS calc() function to the maximum.
+
+Particularly useful for packages like [rework-calc](https://github.com/reworkcss/rework-calc) or [postcss-calc](https://github.com/postcss/postcss-calc).
+
+## Installation
+
+```console
+$ npm install reduce-css-calc
+```
+
+## Usage
+
+### `var reducedString = reduceCSSCalc(string, precision)`
+
+```javascript
+var reduceCSSCalc = require('reduce-css-calc')
+
+reduceCSSCalc("calc(1 + 1)")
+// 2
+
+reduceCSSCalc("calc((6 / 2) - (4 * 2) + 1)")
+// -4
+
+reduceCSSCalc("calc(1/3)")
+// 0.33333
+
+reduceCSSCalc("calc(1/3)", 10)
+// 0.3333333333
+
+reduceCSSCalc("calc(3rem * 2 - 1rem)")
+// 5rem
+
+reduceCSSCalc("calc(2 * 50%)")
+// 100%
+
+reduceCSSCalc("calc(120% * 50%)")
+// 60%
+
+reduceCSSCalc("a calc(1 + 1) b calc(1 - 1) c")
+// a 2 b 0 c
+
+reduceCSSCalc("calc(calc(calc(1rem * 0.75) * 1.5) - 1rem)")
+// 0.125rem
+
+reduceCSSCalc("calc(calc(calc(1rem * 0.75) * 1.5) - 1px)")
+// calc(1.125rem - 1px)
+
+reduceCSSCalc("-moz-calc(100px / 2)")
+// 50px
+
+reduceCSSCalc("-moz-calc(50% - 2em)")
+// -moz-calc(50% - 2em)
+```
+
+See [unit tests](test/index.js) for others examples.
