Swfdec Wiki - PreCommitHook

Here is a pre-commit hook that can be used with GIT to check the following things:

swfdec_initialize.h and swfdec_as_initialize.h are in sync with the corresponding .as-files
test/trace/Makefile.am doesn't contain any files that haven't been added
test/trace/Makefile.am contains all files from test/trace directory
In test/trace directory every *.swf file has a *.swf.trace directory and vica versa

To use, save as .git/hooks/pre-commit and make executable. Requires Ruby and Ming

{{{#!/usr/bin/ruby
