Generating statistics from Git repository [closed]

I'm looking for some good tools/scripts that allow me to generate a few statistics from a git repository. I've seen this feature on some code hosting sites, and they contained information like...

• commits per author
• commits per day/week/year/etc.
• lines of code over time
• graphs
• ... much more

Basically I just want to get an idea how much my project grows over time, which developer commits most code, and so on.

commits per author

git shortlog -s -n 

Beside GitStats (git history statistics generator) mentioned by xyld, written in Python and requiring Gnuplot for graphs, there is also

• gitstat (SourceForge) project (web-based git statistics interface), written in PHP and Perl,
• Git Statistics, aka gitstats (metrics framework designed to gather statistics on git repositories), written in Python, result of git-statistics project at Google Summer of Code 2008 This is not a web app
• gitinspector Is a rather new, CLI based Python tool for generating nice reports
• Hercules - native app without dependencies, written in Go, which specializes in advanced analysis types.

I'm doing a git repository statistics generator in ruby, it's called git_stats.

You can find examples generated for some repositories on project page.

Here is a list of what it can do:

• General statistics
  • Total files (text and binary)
  • Total lines (added and deleted)
  • Total commits
  • Authors
• Activity (total and per author)
  • Commits by date
  • Commits by hour of day
  • Commits by day of week
  • Commits by hour of week
  • Commits by month of year
  • Commits by year
  • Commits by year and month
• Authors
  • Commits by author
  • Lines added by author
  • Lines deleted by author
  • Lines changed by author
• Files and lines
  • By date
  • By extension

If you have any idea what to add or improve please let me know, I would appreciate any feedback.

I tried http://gitstats.sourceforge.net/, starts are very interesting.

Once git clone git://repo.or.cz/gitstats.git is done, go to that folder and say gitstats <git repo location> <report output folder> (create a new folder for report as this generates lots of files)

Here is a quick list of stats from this:

• activity
  • hour of the day
  • day of week
• authors
  • List of Authors
  • Author of Month
  • Author of Year
• files
  • File count by date
  • Extensions
• lines
  • Lines of Code
• tags
