Git: Run through a filter before commiting/pushing?

Is there a way to run the changed files throu开发者_开发知识库gh a filter before doing the commit? I wish to make sure the files follows the coding standards for the project.

I would also like to compile and run some test before the commit/push actually takes place, so I know everything in the repo actually works.

Pre-commit hooks. Read up on git hooks. The Git Book has an example of how to write a Ruby script to run RSpec tests, for instance.

You just save the executable as .git/hooks/pre-commit - using a hashbang to specify the language. It is just an ordinary shell script, although you can use any scripting language, so long as it returns 1 if there is a problem and 0 if there isn't.

For the filter part, I would recommend a smudge/clear driver, with the 'clear' script containing all the formatting or checking you need (executing on commit)

You can declare this git attribute filter driver only for certain types of files, only for certain directories within your repo.
