Jekyll plugins for rendering compass stylesheets and auto-converting coffeescript files without requiring YAML front-matter.

coffeescript.rb

require "coffee-script"

module Jekyll

  # Automatically force coffeescript files to be compiled, even if they don't
  # have the YAML front-matter.
  class CoffeeConvertor < Generator
    def generate(site)
      converted = []
      site.static_files.each do |sf|
        if sf.path =~ /\.coffee\Z/
          converted << sf

          path = sf.path.sub site.source, ""
          dir = File.dirname path
          filename = File.basename path

          # force jekyll to consider this a renderable page
          site.pages << Page.new(site, site.source, dir, filename)
        end
      end

      # don't preserve the coffeescript version
      converted.each { |c| site.static_files.delete c }
    end
  end

  # from https://gist.github.com/phaer/959938
  class CoffeeScriptConverter < Converter
    safe true
    priority :normal

    def matches(ext)
      ext =~ /coffee/i
    end

    def output_ext(ext)
      ".js"
    end

    def convert(content)
      begin
        CoffeeScript.compile content
      rescue StandardError => e
        puts "CoffeeScript error:" + e.message
      end
    end
  end
end

compass.rb

require "compass"
require "compass/exec"

module Jekyll

  class NoopFile < StaticFile
    def write(dest)
      # nothing, the file's already there
    end
  end

  # Adapted from https://gist.github.com/parkr/2874934
  # Expects the destination directory as configured in _stylesheets/config.rb to
  # be "../_site/stylesheets".
  class CompassGenerator < Generator
    def generate(site)
      dir = "_stylesheets"

      compile = Compass::Commands["compile"].new(dir, {})
      puts
      compile.execute

      Dir.glob(File.join(dir, "*.scss")).each do |scss|
        filename = File.basename(scss).sub(".scss", ".css")

        # make sure the newly-generated file doesn't get cleaned:
        site.static_files << NoopFile.new(site, site.source, "stylesheets", filename)
      end
    end
  end

end
