switch haml to erb

un_haml.rb

## based on the example at:
## http://gist.github.com/17371
##
## put me in lib/un_haml.rb (in the haml-based project)
## 
## call me on the command line thus:
## $ script/runner UnHaml app/views/layouts/application.html.haml
## $ script/runner UnHaml */*/*/*.haml
##
class UnHaml < Haml::Engine

  def push_script(text, preserve_script = false, in_tag = false, preserve_tag = false,
                  escape_html = false, nuke_inner_whitespace = false)
    push_text "<%= #{text.strip} %>"
  end
  
  def push_silent(text, can_suppress = false)
    push_text "<% #{text.strip} %>"
  end

  ARGV.each do |haml_file|
    template = File.read(haml_file)
    outfile = haml_file.sub(/.haml$/, '') + '.erb'
    
    if File.exists?(outfile)
      puts "  !!!! Skipping #{haml_file} because #{outfile} already exists"
    else
      puts "     IN: #{haml_file}  OUT: #{outfile}"
      unhaml = UnHaml.new(template)
      File.open(outfile, 'w') {|f| f.write(unhaml.render) }
    end
  end
