List all colours in a CSS file command - TextMate

23 May 2007


      I've made a command which will list all colours in a CSS file as a list of
swatches.
At the minute it only does Hex colours also I would like it if you could
click
colours and it would jump to them in your document but I lack the ruby
skills as I'm sure you will notice from the shoddy
"colourArrayToTrim.each" bit.
Anyway some people might find it useful
input:entire document
output:show as HTML
activation:Key cmd+shift+opt+ctrl+c (ALL modifiers + C, to show ALL
colours ;) )
scope: source.css
Code as follows:
#!/usr/bin/env ruby
file = STDIN.read
fileName = ENV['TM_FILENAME']
hex = Regexp.new(/(#(\d|[a-f]|[A-F]){3,6})/)
colourArrayToTrim = file.scan(hex)
colourArray = []
colourArrayToTrim.each { |colour|
    colourArray.push colour.shift
}
