gitalyse computes some statistics about the history of a git repository
These are simple BSD-licensed shell scripts and a wrapper command-line
tool for calculating contributions by different authors to a git
repository. It can count commits and lines added by different authors
over all history or a range of commits.
The analyses can be run most easily with
gitalyse authors
gitalyse lines
gitalyse types
All accept an optional range of a form accepted by git-rev-parse. The
types command additionally accepts four mode options: --commits,
--files, --commit-percent, and --file-percent.
The authors analysis produces output like this:
Author Commits Proportion
Linus Torvalds 69 72.63%
Junio C Hamano 12 12.63%
Petr Baudis 10 10.52%
David Woodhouse 2 2.10%
Ingo Molnar 1 1.05%
Christopher Li 1 1.05%
95 100.00%
The lines analysis produces output like this:
Author Lines Added Proportion Commits Average
Linus Torvalds 4,390 85.92% 69 63.62
Junio C Hamano 283 5.53% 12 23.58
Petr Baudis 209 4.09% 10 20.90
David Woodhouse 173 3.38% 2 86.50
Ingo Molnar 9 0.17% 1 9.00
Christopher Li 45 0.88% 1 45.00
5,109 100.00% 95 53.77
The types analysis produces various outputs according to the given mode.
In commit mode, it shows the number of commits by each author touching
each file type (determined by extension). In files mode, it lists the
raw number of files of each type modified. In commit-percent mode, it
gives the percentage of commits by each author modifying each file type.
In file-percent mode, it gives the percentage of modifications to each
file type made by each author.
gitalyse can be configured to ignore certain files or authors in a
repository using a .gitalyse file in the repository root. See the --help
output for details.
