Approximate code churn as described by Brikman's article https://www.ybrikman.com/writing/2018/08/12/the-10-to-1-rule-of-writing-and-programming/
hofs-churn does not calculate code churn exactly as in the article. While the methods are the same, small variations may exist (for example, hofs-churn calculates jQuery's ratio as 13.82 while the article shows it is 15.)
Want to get started faster? Just run sudo bash setup.sh to install all of these requirements.

git
apt-get install git
- create a file called
git_repos.txt, with lines with the Github repos that will be analyzed. For example,Decagon/hofs-churn. - run the following script (which will download the repo from Github.com, calculate stats, then delete it.)
while read line; do
git clone https://github.com/$line.git github_repo;
bash ./hofs-churn github_repo "$line";
rm -rf github_repo;
done < git_repos.txt > results.txt
If you want to run it on a local repo, or just a single already downloaded but cloned repo, run bash ./hofs-churn path-to-git-repo github-repo-name;
The results will be in results.txt.

Run git config --global merge.renameLimit 999999 and git config --global diff.renameLimit 999999 (run at your own risk!) This will greatly increase processing time for larger repos. https://stackoverflow.com/questions/7830728/
Git asks for my username and password when cloning a bunch of repos; how do I stop it from asking me?
You can run hofs-churn with the timeout command (get it from apt-get install timeout.) For example, timeout 1m bash ./hofs-churn to make hofs-churn stop after maximum of one minute, irregardless if it's stuck or not.
It appears to be something with unicode, usually with a .xcodeproj files and other non-important files, but otherwise the rest of the clone should complete ok.
Run the script with the timeout command so that when Git gets stuck on the no space left on device error, timeout will kill git, then the rm -rf github_repo will complete, freeing up space for the next loop (ugly hack.) Try using cgroups perhaps. Try cloning one branch (the main branch) instead of all of them (haven't tried this yet.) I'm not sure how that would change the ratio, though, as I'm not sure if git log tracks branches.
