pyonji is a useful tool to send patches to mailing lists, to contribute to projects hosted on sr.ht for example. It is a friendly TUI alternative to using git-send-email directly, but there are still some essentials to note:

• ensure th to address is set (or pass --to)
  git config --local sendemail.to

• use origin/master or HEAD~n for the --base option, this determines what is included in the patch series

• when sending to a public-inbox style list, ensure the subject prefix is set
  git config --local format.subjectprefix

• when writing the cover letter, note that the first paragraph is parsed as the subject of the patch series, see –cover-from-description

I keep a branch with some convenience patches on top of upstream, that make working with it easier for me: https://git.sr.ht/~robertgzr/pyonji/log/devel
