As long as the the tool is able to do the formatting of a given file
using only that one file, the git-hooks are ready. There is a
style_checker option which is currently calling a script that does
nothing. But if we have some tools that check things such as formatting,
copyright header format, etc, it's easy to insert them and reject
the commit.

The problem is that this arrives too late in the process, IMO, because
by then, the review has already gone through. For a formatting issue,
one could argue that the change is trivial, and therefore automatically
re-approved, but this is not ideal.

What we would want is some kind of CI system which, from the moment
the developer proposes a patch, gets the change validated through
the CI. Style-checking is usually quick, so a good candidate for
a CI. But how to integrate that without starting to re-invent
one of those existing Git review or Git hosting systems that already
exist?

What this discussing is showing, IMO, is that the email-based system
of proposing and reviewing patches may be fast and comfortable, but
has some limitations compared to other more modern systems that seem
hard to overcome. We can find technical solutions that overcome those
issues, but each time I try this exercise, I find myself thinking
the problem has already been solved is there for the taking if only
we could accept email-based workflows might be degraded, possibly
to the point where it becomes more productive to use the recommended
interface (e.g. website).

Good or bad, my concern is that the younger generation views emails
as antiquated and at the same time they have grown up learning about
collaboration using systems such as GitLab or GitHub.

I apologize for widening the discussion from code formatter to
review system. It's not how I planned this message when I started
replying, but it seemed natural to add the comment about how we
manage patch submissions and how we do reviews.
