A rakefile for 'compiling' haml and sass. Some is custom nosense so it might need to be modified if you want to use it.

Rakefile

include Rake::DSL

def rebuild(relative)
    puts "------ change detected in #{relative}"
    if relative.pathmap("%x") == ".scss"
        sh 'sass', '--no-cache', '-r', './sass/addons/bourbon/lib/bourbon.rb', relative, "../www/stylesheets/"+relative.pathmap("%n.css")
    elsif relative.pathmap("%x") == ".haml"
        sh 'haml', '-f', 'html5', relative, "../www/"+relative.pathmap("%n.html")
    end
end


desc "Watch the site and regenerate when it changes"
task :watch do
    require 'fssm'
    puts ">>> Watching for Changes <<<"
    FSSM.monitor("#{File.dirname(__FILE__)}", '*/*') do
        update {|base, relative| rebuild(relative)}
        delete {|base, relative| rebuild(relative)}
        create {|base, relative| rebuild(relative)}
    end
end

hmmm. --no-cache does not seem to prevent the cache from being created.. must investigate
