Build Status

gitfiti noun : Carefully crafted graffiti in a github commit history calendar.

An example of gitfiti in the wild:
alt text
is a tool I wrote to decorate your github account's commit history calendar by (blatantly) abusing git's ability to accept commits in the past.

generates a bash script:
that makes commits with the GITAUTHORDATE and GITCOMMITTERDATE environment variables set for each targeted pixel.

Since this is likely to clobber repo's history, I highly recommend that you create a new github repo when using gitfiti. Also, the generated bash script assumes you are using public-key authentication with git.

Pixel Art:

Included "art" from left to right: kitty, oneup, oneup2, hackerschool, octocat, octocat2


  1. Create a new github repo to store your handiwork.
  2. Run
    and follow the prompts for username, art selection, offset, and repo name.
  3. Run the generated
    from your home directory (or any non-git tracked dir) and watch it go to work.
  4. Wait... Seriously, you'll probably need to wait a day or two for the gitfiti to show in your commit graph.

User Templates

The file format for personal templates is the following:

  1. Each template starts off with a ":" and then a name (eg. ":foo")
  2. Each line after that is part of a json-recognizable array.
  3. The array contain values 0-4, 0 being blank and 4 being dark green.
  4. To add multiple templates, just add another name tag as described in 1.

For example:


This would output a 7 x 7 light green square with a single blank center square.

Once you have a file with templates, enter its name when prompted and the templates will be added to the list of options.


Fortunately if you regret your gitfiti in the morning, removing it is fairly easy: delete the repo you created for your gitfiti (and wait).
