gitstats filter files

leave a comment »


Currently gitstats does not allow to filter files by extensions, and the only way is as author suggests:

https://github.com/dcramer/gitstats/blob/master/doc/gitstats.pod
Q: I have files in my git repository that I would like to exclude from the statistics, how do I do that?
A: At the moment the only way is to use git-filter-branch(1) to create a temporary repository and generate the statistics from that.

below is a short script on how to prepeare your repository for such filtered gitstats statistics calcualtion:

i assume you have copied your repository to some temporary folder, actually all below changes can be reverted but to be safe do it in temporary dir.

# clear file list to be removed from statistics calculation
$ rm ~/temp_gitstats_filter.txt

# get latest changes
$ git pull

# create a list of files excluding the ones ending with java and xml, those files will not be processed by gitstats
$ for i in `git ls-files | grep -Ev ‘^.*.(java|xml)$’`; do echo “$i” >> ~/temp_gitstats_filter.txt; done

# remove all the files from previously created list in current repository
$ git filter-branch -f –tree-filter ‘cat ~/temp_gitstats_filter.txt | xargs rm -f’ HEAD

# now execute your gitstats command (should be fixed for your needs)
$ gitstats .git /var/www/html/git_stats

# reset all the changes filter-branch have done
$ git reset –hard refs/original/refs/heads/master
