$ git-heatmap

# on a repository elsewhere
$ git-heatmap -r /path/to/repo

# on multiple repositories!
$ git-heatmap -r /path/to/repo -r /path/to/other

# limit by author email
$ git-heatmap -a me@myself.com

# limit by multiple authors email
$ git-heatmap -a me@myself.com -a him@himself.com

# pick a specific branch
$ git-heatmap -b main

# pick multiple branches
$ git-heatmap -b main -b develop

# start from date
$ git-heatmap -s 2023-02-01

How about some character and color change as well?

You can do this via:

# change characters
$ git-heatmap -c '⊚'

# change colors
$ git-heatmap -sh "255;255;0"

FAQ

Why?

Mostly fun, I like things cli. It's also rather annoying that github's heatmap only targets the primary branch of a repository.

Does this count any contribution other than commits?

No, this is purely commits, including merge commits (I think! :-))

What branch does it pick if I didn't specify one?

All branches!

But commits are the same in more than one branch!

Yes, that's why it only counts unique commit hashes.

The months labels aren't in line with the github heatmap

Github got it wrong, check any month's start date and notice how they push the label one column further. If you still feel they got it right, create an issue and show a screenshot, I'll fix it.

This will be slow on large repositories!

No, this internally uses git-rev-list.

Why not make this a git extension?

That was the original plan, but we are where we are...

Can I...

Yes you can. Remember this is meant as tiny fun project.
