git-score

git-score is a script that computes 'scores' for authors who have contributed to a git repository. It displays aggregate stats in a concise format for human consumption and provides a rough estimation of developer involvement in a project.

Installation

Copy git-score to somewhere in your PATH. A good solution is to place a git-score symlink in ~/bin that points to your git-score repository.

Usage

Inside a git repository, just run

% git-score

It takes the following arguments directly:

-e, --exclude=<pattern>
  Tallies scores per-file, and if <pattern> matches the filename.
  This is useful to exclude directories or particular file extensions.
  Warning: may run much slower. Still untested on very large repos.

-i, --include=<pattern>
  Same as exclude, but the reverse (<pattern> must match).
  Include and exclude can be used in conjunction.

-o, --order=[+-]<field>
  Sorts by chosen <field>. Prepend [+,-] for [ascending, descending]
  <field> must be one of: author, files, commits, delta, added, removed
  All fields (except author) default to descending.

-r, --repo=<path>
  Specify a path to the git repository.  Can be specified multiple times to
  aggregate stats across multiple repositories.

-h, --help
  Shows available options.

All other arguments not beginning with a hypen ('-') will be passed to git log. This way, you can specify revision ranges to narrow scoring to a particular set of commits.

% git-score 61bf126e..HEAD

Note: The hyphen ('-') is optional: git score works too on recent versions of git.
