- UglifyCSS is a port of [YUI Compressor](https://github.com/yui/yuicompressor) to [NodeJS](http://nodejs.org) for its CSS part. Its name is a reference to the awesome [UglifyJS](https://github.com/mishoo/UglifyJS) but UglifyCSS is not a CSS parser. Like YUI CSS Compressor, it applies many regexp replacements. Note that a [port to JavaScript](https://github.com/yui/ycssmin) is also available in the YUI Compressor repository.
-
- UglifyCSS passes successfully the test suite of YUI compressor CSS.
-
- Be sure to submit valid CSS to UglifyCSS or you could get weird results.
-
- ### Installation
-
- For a command line usage:
- ```sh
- $ npm install uglifycss -g
- ```
-
- For API usage:
- ```sh
- $ npm install uglifycss
- ```
-
- From Github:
- ```sh
- $ git clone git://github.com/fmarcia/UglifyCSS.git
- ```
-
- ### Command line
-
- ```sh
- $ uglifycss [options] [filename] [...] > output
- ```
-
- Options:
-
- * `--max-line-len n` adds a newline (approx.) every `n` characters; `0` means no newline and is the default value
- * `--expand-vars` expands variables; by default, `@variables` blocks are preserved and `var(x)`s are not expanded
- * `--ugly-comments` removes newlines within preserved comments; by default, newlines are preserved
- * `--cute-comments` preserves newlines within and around preserved comments
- * `--convert-urls d` converts relative urls with the `d` directory as css location
- * `--debug` prints full error stack on error
-
- If no file name is specified, input is read from stdin.
-
- ### API
-
- 2 functions are provided:
-
- * `processString( content, options )` to process a given string
- * `processFiles( [ filename1, ... ], options )` to process the concatenation of given files
-
- Options are identical to the command line:
- * `<int> maxLineLen` for `--max-line-len n`
- * `<bool> expandVars` for `--expand-vars`
- * `<bool> uglyComments` for `--ugly-comments`
- * `<bool> cuteComments` for `--cute-comments`
- * `<string> convertUrls` for `--convert-urls d`
- * `<bool> debug` for `--debug`
-
- Both functions return uglified css.
-
- #### Example
-
- ```js
- var uglifycss = require('uglifycss');
-
- var uglified = uglifycss.processFiles(
- [ 'file1', 'file2' ],
- { maxLineLen: 500, expandVars: true }
- );
-
- console.log(uglified);
- ```
