Extract from CSS

Extract information from CSS code.

For now, it extracts class names and ids.

Installation

Dependencies:

  • node >= 0.10
  • npm >= 1.3.7 (package usage)
  • npm >= 2.0.0 (package development)
npm install extract-from-css

Usage

var extract = require('extract-from-css');

var code = '.list-item { background: red; } \
  /* comment */ \
  #main-header { background: black; } \
  .list-item-title:hover { font-weight: bold; } ';

extract(['ids', 'classes'], code);
// {
//   ids: [ 'main-header' ],
//   classes: [ 'list-item', 'list-item-title' ]
// }

extract.extractClasses(code);
// [ 'list-item', 'list-item-title' ]

extract.extractIds(code);
// [ 'main-header' ]

Works with nested rules (inside media queries, supports…), complex selectors and escaped characters and unicode symbols (♠, ♥, ★…) in class names and ids. See tests.
