Git Py Stats

Git Py Stats is a Python-based fork inspired by git-quick-stats. It offers a similar set of git statistics and reports, but it's built entirely using Python 3, providing improved cross-platform compatibility and ease of maintenance.

Why Git Py Stats?

While git-quick-stats is a fantastic tool, it has some limitations due to its reliance on Bash and external utilities:

• Cross-Platform Compatibility: git-quick-stats can have issues running on different platforms. For example, macOS requires GNU versions of certain utilities for proper functionality, and the Windows version either requires WSL or Cygwin to run.
• Dependency on External Tools: Although it is written in Bash, it depends heavily on external tools like tput, column, and grep, which may not be installed depending on how the user's system is configured.
• Robust File Generation: git-quick-stats has the ability to export stats in JSON and CSV format, but they are home-grown implementations that are currently in experimental mode.
• Difficult to Test and Extend: Bash scripts are inherently harder to test and extend compared to a Python-based solution that can leverage unittest.

Git Py Stats tackles these challenges by leveraging Python's standard library, guaranteeing that it incorporates code vetted by the Python team and operates smoothly on any platform with Python 3 installed. It stays true to the essence of git-quick-stats by ensuring that no dependencies beyond Python 3 and git are ever required.

Features

Git Py Stats aims to maintain feature parity with git-quick-stats with features such as:

• Contribution stats by author
• Git changelogs and stats by branch or author
• Commits analysis by date, month, year, weekday, and hour
• Branch history and contributor analysis
• Suggested code reviewers based on commit history
• CSV and JSON output for various statistics

and more in both interactive and non-interactive modes.

Changes from Original

While this project aims to be feature-complete and 1:1 with git-quick-stats, there may be instances where this version differs from the base project. The following is a list of differences that this project will maintain compared to the parent project:

• Author, dates, and branch names can be passed via cmdline without interaction by the user. This means you can now do git-py-stats -L "John Doe" instead of being prompted to enter the name after executing the non-interactive cmd.
• CSV output is now saved to a file instead of printing out to the terminal. This file will be saved to wherever the process was executed. The name will be git_daily_stats.csv
• JSON output is saved to a file wherever the process was executed instead of one that is provided by the user. The name will be git_log.json
• JSON and CSV formatting has changed slightly from the original.
• The New Contributors function shows the user's name next to the email in case no known mailmap has been implemented for that user.

Requirements

• Python 3.8+: Git Py Stats requires Python 3.8 or higher installed on your system. While it may work with older versions, there is no guarantee as it is currently untested with versions below 3.8. You can check your Python version with:

  python --version

  If your python is symlinked to Python 2, you can use pyenv to switch between Python versions.

• Git: Git should be installed and available in your system's PATH.

Installation

Using PyPI

1. Install Using pip:

   pip install git-py-stats

   That's it! You can now use git-py-stats anywhere on your system while inside of a git repo!

   If you experience conflicts with other packages, try using venv

Using setup.py

If you prefer using setup.py directly:

1. Clone the Repository:

   git clone https://github.com/tomice/git-py-stats.git
   cd git-py-stats

2. Install the Package:

   python setup.py install

   That's it! You can now use git-py-stats anywhere on your system while inside of a git repo! If you don't have admin permissions, you can use the --user flag at the end of the command to install this locally.

From Source

1. Clone the Repository:

   git clone https://github.com/tomice/git-py-stats.git
   cd git-py-stats

2. Set PYTHONPATH:

   Set the root of git-py-stats to be prefixed to your PYTHONPATH:

   export PYTHONPATH=$(pwd):$PYTHONPATH

   That's it! You can now use git-py-stats anywhere on your system while inside of a git repo, albeit with a slight modification. Commands will need to be done in the following manner:

   python -m git_py_stats.main --help

   This will tell Python to run the git_py_stats.main module directly. This method is usually best for devs who want to help contribute to the project without going through the install process a normal end user would.

Usage

You can run Git Py Stats in both interactive and non-interactive modes:

Interactive Mode

Simply run the tool without any arguments to enter the interactive menu:

git-py-stats

Non-Interactive Mode

Run the tool with specific command-line options for direct output. For example:

• Detailed Git Stats:

  git-py-stats -T

• Git Stats by Branch:

  git-py-stats -R master

• List Contributors:

  git-py-stats -C

For a full list of available options, run:

git-py-stats --help

Advanced Usage

It is possible for git-py-stats to read shell environment variables just like git-quick-stats does. As it aims to maintain 1:1 compatibility, all of the same arguments work the same as the parent project.

Git Log Since and Until

You can set the variables _GIT_SINCE and/or _GIT_UNTIL before running git-py-stats to limit the git log. These work similar to git's built-in --since and --until log options.

export _GIT_SINCE="2017-01-20"
export _GIT_UNTIL="2017-01-22"

Once set, run git-py-stats as normal. Note that this affects all stats that parse the git log history until unset.

Git Log Limit

You can set variable _GIT_LIMIT for limited output. It will affect the "changelogs" and "branch tree" options. The default limit is 10.

export _GIT_LIMIT=20

Git Log Options

You can set _GIT_LOG_OPTIONS for git log options:

export _GIT_LOG_OPTIONS="--ignore-all-space --ignore-blank-lines"

Git Pathspec

You can exclude a directory from the stats by using pathspec.

export _GIT_PATHSPEC=':!directory'

You can also exclude files from the stats. Note that it works with any alphanumeric, glob, or regex that git respects.

export _GIT_PATHSPEC=':!package-lock.json'

Git Merge View Strategy

You can set the variable _GIT_MERGE_VIEW to enable merge commits to be part of the stats by setting _GIT_MERGE_VIEW to enable. You can also choose to only show merge commits by setting _GIT_MERGE_VIEW to exclusive. Default is to not show merge commits. These work similar to git's built-in --merges and --no-merges log options.

export _GIT_MERGE_VIEW="enable"
export _GIT_MERGE_VIEW="exclusive"

Git Branch

You can set the variable _GIT_BRANCH to set the branch of the stats. Works with commands --git-stats-by-branch and --csv-output-by-branch.

export _GIT_BRANCH="master"

Color Themes

You can change to the legacy color scheme by toggling the variable _MENU_THEME between default and legacy

export _MENU_THEME="legacy"
