git-author-stats

This package provides a CLI and library for extracting author "stats" (insertions and deletions) for a Git repository or Github organization.

• Documentation
• Contributing
• Report a Bug

Under the hood, these metrics are obtained by:

1. Cloning truncated versions of all specified repositories (or all repositories in a specified Github organizations) into temp directories
2. Calculating a series of date ranges based on the temporal limits and frequency you've specified
3. Using git log --numstat to get a count of the insertions and deletions made by each author during each date range

Please note that this package does not provide functionality for aggregation or analysis of the metrics extracted, instead the output is provided in a format suitable for use with tools such as polars, pandas, and pyspark.

All stats obtained from this package will be unique when grouped by url + commit + author_name + file, and include the following fields:

• url (str): The URL of the repository (provided because stats for multiple repositories can be obtained with one function call or command)
• since (date|None): The start date for a pre-defined time period as determined by frequency and time range parameters provided by the user
• before (date|None): The (non-inclusive) end date for a pre-defined time period as determined by frequency and time range parameters provided by the user
• author_date (datetime.datetime|None): The date and time of the author's commit
• author_name (str): The name of the author
• commit (str): The abbreviated commit hash
• file (str): The relative path of the modified file
• insertions (int): The number of lines inserted in this commit (please note that this is always 0 for binary files)
• deletions (int): The number of lines deleted in this commit (please note that this is always 0 for binary files)

Please note that:

• The fields since and before are provided as a convenience for easy aggregation of stats, based on parameters provided by the user, but do not provide any additional information about the commit or file
• All dates and times are expressed in coordinated universal time (UTC), as timezone-unaware datetime.datetime or datetime.date objects in python, and output in ISO 8601 format when written to CSV/TSV files and/or console output

Installation

You can install git-author-stats with pip:

pip3 install git-author-stats

Please note that you will need to specify the extra "github" in your pip install command if you want to extract stats from all repositories owned by a Github organization without needing to provide each repository URL explicitly:

pip3 install 'git-author-stats[github]'
