Cross-platform: recompile LaTeX documents using Ruby, Guard

gistfile1.txt

# Tested with Ruby 1.9
# Needs gem "guard" (https://github.com/guard/guard)
# Needs gem "guard-shell" (https://github.com/guard/guard-shell)
# Uses process "growlnotify" (http://growl.info/extras.php)
# Uses process "pdflatex" from standard TeXLive distribution

guard 'shell' do
  watch(%r{(.+)\.tex}) do |m| 
    `growlnotify -m #{m[0]} Recompiling` 
    `pdflatex -interaction=batchmode #{m[0]} >/dev/null`
  end
end
