Rio is one of my favorite gems. I find it a pleasure to use. Today I wanted to create a build script for my SyntaxHighlighter.

require 'rio'

packer        = 'Packer.exe'
build         = rio('dp.SyntaxHighlighter').rmtree.mkpath
scripts       = rio(build, 'Scripts').mkpath
styles        = rio(build, 'Styles').mkpath
uncompressed  = rio(build, 'Uncompressed').mkpath

rio('../Scripts').each do |file|
  next if file =~ /\.svn/

  puts "Copied %s" % file.filename

  file > scripts
  next if not file.ext? =~ /\.js/

  file > uncompressed

  file = rio(scripts, file.filename.to_s)
  name = file.to_s
  file.rename!("#{file}.tmp")

  `"#{packer}" -o "#{name}" -m jsmin "#{file}"`
  file.delete
end

rio('../Styles/SyntaxHighlighter.css') > styles

puts `rar.exe a dp.SyntaxHighlighter.rar #{build}`build.rmtree

The script rebuilds the following tree structure:

.
  dp.SyntaxHighlighter
    Scripts
    Styles
    Uncompressed

It then makes two copies of JavaScript files into Scripts and Uncompressed, packs one copy using a command line JavaScript packer and finally makes a RAR package out of the whole folder.

At the end, it deletes the temporary build folder and I end up with a single RAR file.
