Script to turn a readable javascript file with whitespace into a URL-encoded bookmarklet string. It doesn't automatically add a self-executing anonymous function, because you guys are smart and should be doing that already. Usage: $ ./bookmarkletize bookmarklet.js #=> "javascript:..."

bookmarkletize.rb

#!/usr/bin/env ruby
#
# Bookmarkletize is a lil script to turn a normal javascript file into a
# (virtually unreadable) URL-escaped string that can be used in a
# bookmarklet. 
#
# Inspiration: http://daringfireball.net/2007/03/javascript_bookmarklet_builder
#
# I could use his script, but come on. It's perl.

say "javascript:#{URI::escape(js)}"
