I was in two minds over bothering to write this because I was shocked you
hadn't already Thomas. Looks like I chose wrong :)

However I had some spare time this afternoon and added line numbers and
made the links work on mine.


#!/usr/bin/env ruby


myFile = STDIN.read
fileName = ENV['TM_FILENAME']

hex = Regexp.new(/(#(\d|[a-f]|[A-F]){3,6})/)


def swatch(colour,lineNumber)
  puts "
  <a href='txmt://open?line=#{lineNumber}' class='colourRow'>
  <div class='swatch'>
  <div style='background-color:#{colour};'></div>
  </div>
  #{colour}<br /><span>#{lineNumber}</span>
  </a>
  "
end


puts '<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"

		}

		a:hover {

		.swatch div {

			height: 18px;
			border: 1px solid #fff;

	</style>

</head>

<body>'

puts "<h2>Colours used #{fileName}</h2>"



lines = myFile.split("\n")
counter = 1
lines.each do |line|
  colourArrayToTrim = line.scan(hex)
  colourArray = []

  colourArrayToTrim.each do |colour|
      colourArray.push colour.shift
  end

  colourArray.each do |colour|
    swatch(colour,counter)
  end
  counter+=1
end

puts "
