Patch for Fantasdic Google Source
I found fantasdic a great powerful dictionary tool with friendly UI and supports multiply sources. Unfortunately, this project seems to be no longer maintained. The latest version is 1.0-beta7.

The google translate source was created in 2007. As the google translate service page changed, this module doesn’t work any more, so I just picked up my vim then created this patch for those still want to use it.
This patch has dependency with ruby’s json module, so before you apply it, run:
sudo gem install json
or
sudo apt-get install libjson-ruby1.8
Download the patch at:

Patch it (Ubuntu installation as example):
cd /usr/lib/ruby/1.8/fantasdic/sources/
sudo patch google_translate.rb /home/sun/google_translate.rb.diff
Restart fantasdic, then your get it works! And this bug is tracked at:
