Git hooks

In my current project we want to make sure the configurations are valid before committing any changes.

By using the git hook pre-commit we can achieve that automatically. Just put a file named pre-commit in the .git/hooks directory and give it executable rights (chmod +x .git/hooks/pre-commit).

#!/bin/sh
rake validate_configs

In this example we call a rake task that does the actual validation. Now, whenever you commit something git makes sure to run this rake task before. You won't be able to commit without a valid configuration.

There are many other hooks you can use. Read more about git hooks here.
