Magic rebase and (re-) format

If you like clean coherent formatted code, you may already use something like clang-format and git hook to ensure format when commit

If you like clean history, you might use a log of rebase.

Sometimes during conflit, format is lost, but it’s pita to fix it afterwards without introducing some commit out of the clean history

I use run-clang-format script with rebase and exec. This will stop rebase if format is not respected

git rebase --exec "./ -r -i \
--style file --extensions inl,cpp,hpp src/" \

When it stops, you can examine the situation with

git status
git diff

Once everything looks good (in case of conflict, simply use remote, and reformat)

git add -u && \
git commit -m"fix format" && \
git rebase --continue

Then rebase -i again so you can squash/fix all “fix format” commits with their immediate ancestor.
