Snap a selfie on every commit
$ npm install --save-dev gitsnap
Commit as usual, and say cheese!
Snaps are stored in .gitsnaps directory, which is added to gitignore by default. Each snap is named by username, branch name, and unix time.
If working with multiple developers, try having everyone on the team install this project and commit the the .gitsnaps directory. Hilarity ensues.
99.9% sure this only works on MacOS. No guarantees for other platforms.
On installation, gitsnap checks if the current project is a working git project by checking for the .git directory. Will have to reinstall if project fails this way.
