'shortlog' script for git

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 




I've been wanting a shortlog script for summarizing my kernel submissions to Linus for a while. This is now written, and the results are attached. Simply use like

	git-shortlog < changes.txt
		or
	git-shortlog changes.txt

The changeset format the Perl script parses is that of
http://www.kernel.org/pub/linux/kernel/people/jgarzik/git-changes-script

I'll change it to parse the git-whatchanged output format sometime soon; Linus hates it when I use git-changes-script since he thinks its ugly :)
