Originally inspired by the sup mail user agent (MUA), notmuch is a
GPL3+ set of tools for for dealing with your mail (stored in
Maildirs or similar) via searching and tagging. On top of the C
bindings and a scriptable command line interface, the project
directly supports user interfaces based on Emacs and VIM as well as
integration with Mutt. We also support python, ruby, and go
bindings. Other projects based on notmuch include curses based
frontends written in python and Mercury, a fork of mutt using
notmuch as a the backend, several web interfaces, and a virtual
filesystem.
Depending on audience demand, I could give a brief a tour of the notmuch "ecosystem", concentrating on the Emacs interface and command line tool. Otherwise, we can discuss what are the most irritating missing features, people can give demos, we can help each other configure various notmuch related things, and just generally have not much of a fixed agenda.
