CommitArt

Modifying the commit history of git repositories in order to write messages in GitHub's contribution graph.

I did this project as a way of learning how to use the Rugged library which is a ruby binding to libgit2.

Check out the picture below or see it live (note: more than a year has passed since I created this, so the contribution graph for this account now looks empty).

Using the letters from the alphabet.yml file, I was able to write GITHUB in the contribution history.

How to run it

First, set environment variable for the script to use. Both the email and the user need to be configured for the script to run. The environment variables for the email and username are COMMIT_ART_EMAIL and COMMIT_ART_USERNAME, respectively.

Then, run

$ ruby commitart.rb /absolute/path/to/existing/repo GITHUB

Assumption: the repository you are targeting already exists.
