Commitstogram

Just put this file in your $PATH and commitstogram 26 your_name someone_else (since 26 weeks ago, compare you to someone else, or just commitstogram 26 your_name for you vs. everyone else.)

for lazy people: (assuming you have ~/.local/bin/ in your $PATH)

curl -fsSL https://gist.githubusercontent.com/alexng353/807594a98ae2e72ce33f1220fa0c0704/raw/279d3479076252ba27ff72ca7d0dce6cce21dc0f/commitstogram -o ~/.local/bin/commitstogram && chmod +x ~/.local/bin/commitstogram

Works on Linux (and probably MacOS) --- No idea if it works on Windows. Put it in Claude and get Claude to write a windows-friendly version.

Pics (or it didn't happen, right?)
