I have been a proponent of pre-commit hooks for a very long time. After doing some searching, I found this lovely gem. It consists of a bunch of checks before you commit your code into the repository. A couple of my favorites:
php– Runs a PHP syntax check on all PHP filesmerge_conflict– Makes sure you aren’t about to commit merge conflicts (you know,>>>>>>>> HEAD, stuff like that)ruby_symbol_hashrockets– Prevents you from committing old-style Ruby hashes (:hello => 'there')
And much more. Highly recommended!
