greenhat

greenhat is a quick hack for decorating your GitHub contribution calendar with commits for the past n days. It uses the GIT_AUTHOR_DATE and GIT_COMMITTER_DATE environmental variables to make commits appear in the past. Be warned that greenhat will clobber your repository's commit history.

How to Use

Place greenhat.py in your Git repository. Make sure your remote repository URL is set, and that you have a public SSH key set up. Then run the script with the python interpreter, with an integer specifying n number of days before today to generate commits for. E.g.,

python greenhat.py <n>

It might take a while to generate all the commits. If greenhat stops before it finishes, you can resume where you last left off by specifying a date before today when you want it to resume, like so:

python greenhat.py <n> <date>

n is the remaining days you want to generate commits for, and date is a date string in the form yyyy-mm-dd (e.g., 2013-04-05).

Arguments

greenhat.py accepts a few arguments to make things more fun or faster.

• --push will perform a git push after each git commit, makes the script much slower.
• --no-sleep will skip the 0.5s sleep between commits, making the script much faster but uses a lot more resources.
• --whatthecommit will use whatthecommit.com to generate commit messages.
• --commits=10 set the maximum number of commits that can happen per day (default is 10).
• --jump=5 randomly jump ahead in time by a random number of days, between 1 and the given value so your calendar contribution calendar isn't quite as decorated (by default days are not skipped)
• --verbose will output additional data to let you see overall process.

These arguments should go before <n> and the optional <date> arguments.

An Example

The following calendar is the result of running python greenhat.py 365:

Beautiful, isn't it?

Enjoy your decorated calendar!
