Nothing bad in knowing how many lines of code or text out there in your repo. You don’t even need your VCS to convey this analytics. All you need is git, grep and wc.

# count lines in .py and .robot files in /nuage-cats dir of the repo
$ git ls-files nuage-cats/ | grep -E ".*(py|robot)" | xargs wc -l
