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 lot 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
Update 2022-05-10
I have switch to pre-commit.ci to perform pre-commit hook and formating, applying the same principle, I run
git rebase --strategy-option=theirs -x 'git reset --soft HEAD~1 && \
git commit -C HEAD@{1}' origin/master Which reset and reapply commits, hence triggering pre-commit hook. Then conflict resolution is nearly the same, I use the following oneliner to fix all possible conflicts
git add -u && git commit -C HEAD@{1} && \
git rebase --continue Older version
I use run-clang-format script with rebase and exec. This will stop rebase if format is not respected
git rebase --exec "./run-clang-format.py -r -i \
--style file --extensions inl,cpp,hpp src/" \
new-base-branch
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.
