UglifyCSS is a port of YUI Compressor, for its CSS part, to NodeJS. Its name is a reference to the awesome UglifyJS but UglifyCSS is not a CSS parser. Like YUI CSS Compressor, it applies many regexp replacements.

Usage: uglifycss [options] css1 [css2] [...] > 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

A port to javascript is also available in the YUI Compressor repository.

2 functions are provided:

• processString( content, options )
• processFiles( [ filename1, ... ], options )

See test.js for example.

UglifyCSS passes successfully the test suite of YUI compressor CSS.
