Ruby code colorizer

Rails

Hi,

Does anyone know of a html code colorizer for ruby source code?
Ideally a typo plugin :slight_smile:

If you have the syntax gem installed, Typo already does this:

<typo:code lang=“ruby”>
some.ruby {|code| here}

Go to your Admin page’s Filters tab to learn more.

You’ll need to modify the stylesheet as mentioned elsewhere, but I
believe the default theme has it already.

I have found that CodeRay[1] is faster and more flexibile then the

syntax gem.

gem install syntax

Then consider the following script:

#######################
#!/usr/bin/env ruby

unless [1,2].include? ARGV.size
$stderr.puts “Usage: #{$PROGRAM_NAME} [file]”
exit 1
end

require ‘rubygems’
require ‘syntax/convertors/html’

convertor = Syntax::Convertors::HTML.for_syntax ARGV.shift

highlighted = convertor.convert(ARGF.read)
highlighted.sub!(/^

/, “<pre class="code">\n”)

puts highlighted

#######################


You’ll need appropriate CSS defined for it. I use the following, derived

from Vim highlighting:


pre.code span.keyword { color: rgb(165, 42, 42); }

pre.code span.module, pre.code span.class { color: rgb(160, 32, 240); }

pre.code span.punct { color: rgb(106, 90, 205); }

pre.code span.ident { color: rgb(0, 0, 0); }

pre.code span.method { color: rgb(0, 139, 139); }

pre.code span.string { color: rgb(255, 0, 255); }

pre.code span.number { color: rgb(255, 0, 255); }

pre.code span.constant { color: rgb(0, 139, 139); }


This is what I use for my (shameless plug!) blog at

redcorundum.blogspot.com. There you go!
