`ctags` doesn't seem to play well with namespaced ruby class names out of the box. Even trying with `--extra=q`. `ripper-tags` seems to fix it.

    map = line.gsub(/^([a-zA-Z0-9:]+)\t.+$/, '\1')
    if name == "" || map != name
      line.gsub(/^#{map}/, name)
    else
      line
    end
  else
    line
  end
end.join("\n")

File.open(tags_file, "w") {|f| f.write(fixed_tags) }
