Quick and dirty Rakefile for a Wordpress project I maintain. Automates the conversion of .po files to .mo files. In this example, it uses all the .po files in the ./lang directory. Also note that I installed gettext via homebrew so the msgfmt binary is not on my path. Rather than muck with my path and risk screwing up OS X's built-in gettext stu…

Rakefile

MSGFMT = "/usr/local/Cellar/gettext/0.18.2/bin/msgfmt"

task :export_mo do |t|
  po_files = Dir.glob(File.dirname(__FILE__) + '/lang/*.po')
  
  po_files.each do |po|
    mo = po.gsub(/.po\Z/, '.mo')
    sh "#{MSGFMT} -o '#{mo}' '#{po}'"
  end
end
