List all colours in a CSS file command - TextMate

24 May 2007


      Thanks for the regex tip Chris, worked great.
The command now displays Hex, RGB and Named colours (thanks to the bit I
copied out of the CSS language file) and I tidied some of the layout up a
bit to fit the longer colour names etc.
So here is my final version
#!/usr/bin/env ruby
myFile = STDIN.read
fileName = ENV['TM_FILENAME']
hex =
Regexp.new(/(#[0-9a-fA-F]{3,6})|(seagreen|hotpink|lawngreen|darkgreen|violet|darkred|crimson|green|sandybrown|navy|magenta|darkslategray|steelblue|silver|darkgrey|mistyrose|gray|aliceblue|blueviolet|lightpink|saddlebrown|chocolate|limegreen|lightslategray|yellowgreen|pink|lightskyblue|indigo|lightblue|floralwhite|navajowhite|mediumvioletred|honeydew|aquamarine|blue|olivedrab|palegreen|slategray|lavenderblush|wheat|moccasin|mediumturquoise|mediumspringgreen|lightcoral|mintcream|tomato|lightgrey|black|darkmagenta|dimgray|darkturquoise|midnightblue|plum|indianred|coral|lightcyan|mediumslateblue|darkcyan|darkslateblue|darkkhaki|ivory|azure|khaki|powderblue|darkgoldenrod|orangered|burlywood|turquoise|royalblue|maroon|cornsilk|antiquewhite|yellow|teal|orange|grey|darkslategrey|slateblue|seashell|darkorchid|snow|lightslategrey|cyan|greenyellow|palevioletred|goldenrod|deepskyblue|lightyellow|lightseagreen|sienna|lemonchiffon|darkviolet|paleturquoise|slategrey|skyblue|purple|mediumpurple|cadetblue|fuchsia|chartreuse|darksalmon|lightgoldenrodyellow|white|springgreen|olive|forestgreen|peachpuff|peru|dimgrey|mediumseagreen|thistle|firebrick|darkgray|mediumaquamarine|darkolivegreen|mediumblue|palegoldenrod|blanchedalmond|ghostwhite|gold|gainsboro|darkseagreen|cornflowerblue|lime|lavender|beige|orchid|mediumorchid|whitesmoke|bisque|lightgray|tan|salmon|rosybrown|red|dodgerblue|brown|aqua|oldlace|deeppink|papayawhip|lightsalmon|lightsteelblue|darkorange|darkblue|linen|lightgreen)|(rgb([0-9]{1,3},[0-9]{1,3},[0-9]{1,3}))/)
