- Configure git.
# ~/.config/git/config
[sendemail]
confirm = auto
smtpServer = smtp.gmail.com
smtpServerPort = 587
smtpEncryption = tls
smtpUser = <gmail email address>
- Configure Authentication.
I believe the simplest setup is to create an application-specific password in Google dedicated to git.
Google Account -> Security -> Signing in to Google : App passwords
This password must be configured in git, but should be kept outside of your main gitconfig (which is likely versioned via a dotfile repo?). To do that, I use git's [include]
directive.
# ~/.config/git/config
[include]
path = config.local # (relative or absolute path to the other config file)
# ~/.config/git/config.local
[sendemail]
smtpPass = <app-specific-password>
Alternatively, check out https://github.com/google/gmail-oauth2-tools/tree/master/go/sendgmail which supports authenticating to GMail with OAuth2.
- Determine your revlist.
To send a single commit, just use the sha. To send a range of commits, you can use start_sha..end_sha
. Most likely, you'll want to send the commits made to a branch that are missing in upstream. For that, you would use: upstream/branch_name..branch_name
You can also use relative numbers to indicate the "previous X commits". e.g. git send-email -3
- Send email:
git send-email <revlist> --to <other@user.com>
- If you receive an error like this:
Can't locate Net/SMTP/SSL.pm in @INC (@INC contains: ...
You may need to upgrade/install the Net::SMTP::SSL or IO::Socket::SSL packages:
sudo -H cpan Net::SMTP::SSL
sudo -H cpan IO::Socket::SSL
- Advanced: configure multiple identites. You may configure multiple smtp servers and switch between them with identities.
[sendemail "gmail"]
smtpUser = jason@gmail.com
smtpServer = smtp.gmail.com
[sendemail "outlook"]
smtpUser = jason@outlook.com
smtpServer = smtp.office365.com
[sendemail]
identity = outlook
After a great deal of effort, I got it all working. See my full instructions on Stack Overflow now, here: https://stackoverflow.com/questions/68238912/how-to-configure-and-use-git-send-email-to-work-with-gmail-to-email-patches-to/68238913#68238913
