default git commit behavior to --allow-empty

Question

I would like to get git commit to have the --allow-empty flag by default (not with an alias).

I search in the git documentation but I didn't find anything about it.

Is there any gitconfig command that can change this?

Answer 1

A quick skim of the git-commit and git-config docs does not reveal such a specific option.

However, you can specify a git alias that does this:

# the --global flag means this works now everywhere, not just in the current repo.
git config --global alias.committ "commit --allow-empty"
# Now use like this:
git committ -m "my empty commit, with a message"

I gave it a try to overwrite alias.commit itself, without the additional t. This does not seem to have any effect.
