I'm trying to write fancy split that puts any message with "[foobar]" in the subject into a specific folder but nothing seems to work.

I have:

(setq nnimap-split-fancy '(|("subject" "\\[foobar\\]" "INBOX.foobar")
                          (...)) 
                          "default") 

but it still ends up in the "default" mailbox.

If I change the regexp to just "foobar" it works (but then it matches other messages I don't want included). I think it's something to do with the escaping of the brackets. I've tried a couple of different of variations of escaping but there's something I'm missing. Or maybe I'm not fancy enough.

    Did you set nnmail-split-methods to nnmail-split-fancy? Aug 6 '15 at 18:37
  • Tassilo Horn: Yep. It works if I do just "foobar" or "f.*bar". I just can't seem to escape the brackets properly.

  • That's strange. Given that this is a regular expression, they are in fact quoted correctly... Aug 8 '15 at 6:57
  • Maybe gnus is doing something to the subject with the brackets at the beginning?

  • I don't know. You could figure out which function evaluates the fancy splits and edebug it in order to see what's happening exactly. Aug 13 '15 at 19:15

Finally figured this out.

Had to use:

(setq nnimap-split-fancy '(|("subject" "\\[foobar]" "INBOX.foobar")
                      (...)) 
                      "default")
