punchcard generator for git commit frequencies

Project description

Simple git punchcard utility, inspired by git-punchcard-plot but rewritten for python3 with matplotlib.



Install or upgrade from PyPI as follows:

pip install --user --upgrade git-punchcard

Also, make sure that $HOME/.local/bin is in $PATH.

To avoid conflicts with other packages, I recommend installing into an isolated environment, e.g. using pipx:

pipx install git-punchcard


Basic usage:

git punchcard

Additional arguments can be specified as follows:

git punchcard [<input path>...] [<options>]
              [--] [<log options>] [<revision range>] [-- <path>...]

For more help on available options, type:

git punchcard -h            # [options]
git help log                # [log options]
git help gitrevisions       # [revision]


The most common builtin options are:

# use a fixed timezone for all commits:
git punchcard --timezone CET
git punchcard --timezone Europe/Berlin
git punchcard --timezone UTC+02:30

# show punchcard with specified y/x axes:
git punchcard -p year/month
git punchcard -p wday/month

# histogram with specified x axis:
git punchcard -p /wday

# set the directory of the git repository (multiple allowed):
git punchcard /path/to/repo

# analyze all repositories in ~/dev:
git punchcard ~/dev/*/.git

# read commit dates from stdin:
git punchcard -

# show a github-like punchcard plot with grid:
git punchcard --grid

By default, each commit’s local timezone is used for the plot. If setting a fixed timezone, it should be specified in terms of the timezone name (e.g. CET or Europe/Berlin), but can also given by ISO 3166 country code or country name (if the timezone is ambiguous we will pick the first entry).

git log options

Additionally, you can pass any options understood by git log to e.g. restrict the range of commits and limit to commits performed by a certain author:

# include only commits by specific author:
git punchcard --author=myself

# consider only only the 20 commits:
git punchcard master~20..master

# commits within a certain time frame:
git punchcard --since="1 year ago" --until=now

# show at which times a certain file/folder is usually edited:
git punchcard --follow -- README.rst docs

# show at which times, people like to merge:
git punchcard --merges

Advanced example

Track evolution of commit activity over the years:

for year in {2016..2019}; do
    git punchcard -o $year.png --title $year \
        --since 1.1.$year --until 31.12.$year
