Is it possible to automatically split a commit for Github compare view?

问题

At our company code reviews are done in Github compare view by adding comments. Of course you can use difftool or someting. But I'd like to know if there is a way to automatically warn / split a commit when it exceeds the Github limits?

回答1:

You can use a pre-commit hook to prevent large commits. E.g. to check the diff's number of lines, save the following as [REPO PATH]/.git/hooks/pre-commit and make it executable (e.g. chmod +x on linux):

#!/usr/bin/env bash
[[ $(git diff --cached | wc -l) > 300 ]] && { echo "Commit too long"; exit 1; }

or check file size:

tmp=$(mktemp /tmp/git_XXXXX)
git diff --cached > "$tmp"
[[ $(ls -l "$tmp" | awk '{print $5}') > 10000 ]] && { echo "Commit too large"; exit 1; }
