Re: Gmail OAuth2 in git send-email

Hi,

We wonder whether git send-email can support Gmail OAuth2 so that we can
seamlessly send patches without having to choose either action. But however,
we have to create a GCP project [1] first in order to enable Gmail API. This
can be overkill for some folks, but unfortunately that's the only way.

Yes, that's how I have mutt and other tools working with my Gmail
account set up.  See [1] for details.

If we want to enable support for Gmail OAuth2, should we hands-off API
configuration to git send-email users, or should we configure it on behalf
of them? Note that when we go the former approach, some Gmail users simply
can't afford GCP pricing for whatever reason

I didn't have to pay for GCP in order to set this up; I only had to
follow the instructions at
https://developers.google.com/identity/protocols/oauth2 to create a
client ID and client secret for oauth access.

Alas, I don't think Git can provide its own client secret to do this
out of the box.  I could imagine Git providing a way to supply an API
key at build time, but distros would need to go through a procedure
similar to [2] to make use of it for their own builds.  If someone
wants to set that up, I think that would make sense as its _own_
separate package --- e.g. a "sendgmail" command that "git send-email"
could use via the --sendmail-cmd option.  That way, it would be useful
for a variety of calling programs and not just Git.

Thanks and hope that helps,
Jonathan
