GIT quick statistics

git-quick-stats is a simple and efficient way to access various statistics in a git repository.

Any git repository may contain tons of information about commits, contributors, and files. Extracting this information is not always trivial, mostly because there are a gadzillion options to a gadzillion git commands - I don't think there is a single person alive who knows them all. Probably not even Linus Torvalds himself :).

Git log since and until

You can set the variables _GIT_SINCE and/or _GIT_UNTIL before running git-quick-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 quick-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"

Ignore authors

You can set the variable _GIT_IGNORE_AUTHORS to filter out specific authors. It will affect the "All contributors", ""Suggested code reviewers" and "New contributors" options.

export _GIT_IGNORE_AUTHORS="(author@examle.com|username)"

Sorting contribution stats

You can sort contribution stats by field name, commits, insertions, deletions, or lines (total lines changed) and order (asc, desc). e.g.: commits-desc

export _GIT_SORT_BY="name-asc"

Commit days

You can set _GIT_DAYS to set the number of days for the heatmap

export _GIT_DAYS=30

Color themes

You can change to the legacy color scheme by toggling the variable _MENU_THEME between default and legacy. You can completely disable the color theme by setting the _MENU_THEME variable to none.

export _MENU_THEME="legacy"
# or
export _MENU_THEME="none"

Installation

Debian and Ubuntu

If you are on at least Debian Bullseye or Ubuntu Focal you can use apt for installation:

apt install git-quick-stats

UNIX and Linux

git clone https://github.com/git-quick-stats/git-quick-stats.git && cd git-quick-stats
sudo make install

For uninstalling, open up the cloned directory and run

sudo make uninstall

For update/reinstall

sudo make reinstall

macOS (homebrew)

macOS requires GNU coreutils to be installed and for the non "g" aliased versions to be exported to your path. The following is an example of how to perform this if you are using Homebrew as your package manager.

brew install coreutils
export PATH="$HOMEBREW_PREFIX/opt/coreutils/libexec/gnubin:$PATH"

From there, you can install via Homebrew as follows:

brew install git-quick-stats

Or you can follow the UNIX and Linux instructions if you wish.

If you would like to default to using the GNU coreutils (recommended), then you can add export PATH="$HOMEBREW_PREFIX/opt/coreutils/libexec/gnubin:$PATH" to your applicable ~/.bash_profile, ~/.zprofile, or other relevant profile based on the shell of your choice.

Windows

If you are installing with Cygwin, use these scripts:

• installer
• uninstaller

If you are wishing to use this with WSL, follow the UNIX and Linux instructions.

Docker

You can use the Docker image provided:

• Build: docker build -t arzzen/git-quick-stats .
• Run interactive menu: docker run --rm -it -v $(pwd):/git arzzen/git-quick-stats
• Docker pull command: docker pull arzzen/git-quick-stats docker repository

System requirements

• An OS with a Bash shell
• Tools we use:

awk
basename
cat
column
date
echo
git

tput
tr
uniq

FAQ

Q: I get some errors after run git-quick-stats in cygwin like /usr/local/bin/git-quick-stats: line 2: $'\r': command not found

A: You can run the dos2unix app in cygwin as follows: /bin/dos2unix.exe /usr/local/bin/git-quick-stats. This will convert the script from the CR-LF convention that Microsoft uses to the LF convention that UNIX, OS X, and Linux use. You should then should be able to run it as normal.

Q: How they could be used in a project with many git projects and statistics would show a summary of all git projects?

A: If you want to include submodule logs, you can try using the following: export _GIT_LOG_OPTIONS="-p --submodule=log" (more info about git log --submodule)

Code reviews

All submissions, including submissions by project members, require review.
We use GitHub pull requests for this purpose.

Some tips for good pull requests

• Use our code
  When in doubt, try to stay true to the existing code of the project.
• Write a descriptive commit message. What problem are you solving and what are the consequences? Where and what did you test? Some good tips: here and here.
• If your PR consists of multiple commits which are successive improvements / fixes to your first commit, consider squashing them into a single commit (git rebase -i) such that your PR is a single commit on top of the current HEAD. This make reviewing the code so much easier, and our history more readable.
