Custom RedCarpet script to use in Marked.app

redcarpet

Not really a big magic here, just a slight modification of the default redcarpet executable file included in the RedCarpet gem. It just enables fenced code blocks. I'll probably revise it to have Albino powered syntax highlight as well.

    #!/usr/bin/env ruby
    # Usage: redcarpet [<file>...]
    # Convert one or more Markdown files to HTML and write to standard output. With
    # no <file> or when <file> is '-', read Markdown source text from standard input.
    if ARGV.include?('--help')
      File.read(__FILE__).split("\n").grep(/^# /).each do |line|
        puts line[2..-1]
      end
    exit 0
    end

    require 'redcarpet'
    STDOUT.write(Redcarpet::Markdown.new(Redcarpet::Render::HTML, :fenced_code_blocks => true).render(ARGF.read))
