NAME
${program} - Simple and efficient way to access various stats in a git repo
SYNOPSIS
For non-interactive mode: ${program} [OPTIONS]
For interactive mode: ${program}
DESCRIPTION
Any git repository contains tons of information about commits, contributors,
and files. Extracting this information is not always trivial, mostly because
of a gadzillion options to a gadzillion git commands.
This program allows you to see detailed information about a git repository.
OPTIONS
-r, --suggest-reviewers
show the best people to contact to review code
-T, --detailed-git-stats
give a detailed list of git stats
-R, --git-stats-by-branch
see detailed list of git stats by branch
-d, --commits-per-day
displays a list of commits per day
-m, --commits-by-month
displays a list of commits per month
-w, --commits-by-weekday
displays a list of commits per weekday
-o, --commits-by-hour
displays a list of commits per hour
-A, --commits-by-author-by-hour
displays a list of commits per hour by author
-a, --commits-per-author
displays a list of commits per author
-S, --my-daily-stats
see your current daily stats
-C, --contributors
see a list of everyone who contributed to the repo
-b, --branch-tree
show an ASCII graph of the git repo branch history
-D, --branches-by-date
show branches by date
-c, --changelogs
see changelogs
-L, --changelogs-by-author
see changelogs by author
-j, --json-output
save git log as a JSON formatted file to a specified area
-h, -?, --help
display this help text in the terminal
ADDITIONAL USAGE
You can set _GIT_SINCE and _GIT_UNTIL to limit the git time log
ex: export _GIT_SINCE=\"2017-01-20\"
You can set _GIT_LIMIT for limited output log
ex: export _GIT_LIMIT=20
You can exclude directories or files from the stats by using pathspec
ex: export _GIT_PATHSPEC=':!pattern'
You can set _MENU_THEME to display the legacy color scheme
ex: export _MENU_THEME=legacy"
