A Python command-line utility to summarize the output of git log --short-stat. It aggregates the number of commits and changes made by each author, allowing for different ordering and output formats.
Count commits and changes by author for each day, from all branches and ignoring merge commits:
git log --all --no-merges --shortstat --date=short | python git_log_summary.py
The git log date format determines the date grouping. For example, here is how to group commits by month:
git log --all --no-merges --shortstat --date=format:'%Y-%m' | python git_log_summary.py
To write to a file, use the output redirection of your shell. For example, to export to a CSV file:
git log --all --no-merges --shortstat --date=short | python git_log_summary.py --output-format csv > commits_summary.csv
git_log_summary.py [-h] [--ordering {chronological,top-changes,top-commits}] [--output-format {text,csv}] [-x [author]]
options:
-h, --help
--ordering {chronological,top-changes,top-commits}
--output-format {text,csv}
-x [author], --exclude [author]
Even though this is a simple script, it was implemented with the following considerations in mind:
- It must be kept as a single file so that it can easily be copy/pasted to be used.
- It should have no dependency except the Python standard library so that it doesn't require a preliminary
pip installto be run. - It should not use any fancy new feature to stay compatible with older versions of Python (it was tested to work with Python 3.6).
- Even though it would probably not be a problem except for a very large git log, the code processing it uses generators as much as possible for memory efficiency.
