psdiff

http://filp.github.io/psdiff

psdiff uses git hooks and the lovely psd.rb library to automagically generate up-to-date image files from PSDs in the repository, allowing you to easily preview them and make use of github's image diff tools.

[ Check out an example diff ](https://github.com/filp/psdiff/commit/44b6b0466fe707396cfd6c771e5d744025e66196?diff-0=1-42)

That's it!

Update: Github now supports PSD viewing!

Check it: Github Blog - PSD Viewing & Diffing

This tool will remain available as it still possibly has its uses outside Github.

How do I install this?

Glad you asked! Couldn't be easier. Just run this in the root of a git repo:

bash <(curl -sSL https://raw.github.com/filp/psdiff/master/install.sh)

Here's what that script does:

1. Scolds you if you don't have Ruby installed (it's required!)
2. Checks if the psd gem is installed and allows you to install it if needed.
3. Downloads the pre-commit hook from this repo to your .git/hooks.

Congrats! Any changes you make to psd files in the repository will now trigger psdiff!

Warning

It's not really a good idea to keep large PSD files in your repositories - this project is partially a proof-of-concept, and partially a helper for existing projects.
