Confusion wrt nnmail-split-fancy

[Jack Twilley]

I read the docs for fancy mail splitting.

I read the docs for replace-match.

I even see the example:

     (any "debian-\\b\\(\\w+\\)@lists.debian.org" "mail.debian.\\1")

But I don't know what it means.  If someone could say something after
the info file demonstrating the effect, that would be nice.

     In this example, messages sent to debian-foo@lists.debian.org
     will be filed in mail.debian.foo.

The reason I ask...

I play Diplomacy online.  I get email messages from a static address
with dynamic subject lines, on which I'd like to filter and file.

Here's a chunk of my summary buffer:

!  [  14: usef@devel.igo.org  ] Diplomacy notice: atom02
!  [  66: usef@devel.igo.org  ] Diplomacy results atom02 S1904M

So I'd want something like this in my nnmail-split-fancy variable:

    (from "usef@devel\\.igo\\.org"
          (| (subject "Diplomacy notice: \\(\\w+\\)")
             (subject "Diplomacy results \\(\\w+\\)")
             "mail.diplomacy.usef.\\1"))

Is that right?  Help? :-)
             
Jack.

        Don't use fancy mail splitting if you can avoid it. It's horrible and
you can do everything with the normal split method. I've gave up fancy
splitting affter being sick of the way it does matching. Unusable. Although it
can be a bit more convenient than the basic way, I'm not ready to use it again
until Lars moves back the matching stuff to the same method as for normal
splitting.

        "any" header matching the regexp will move the message to the group
"mail.debian.<what's in the 1st paren group in the regexp>"

        Your "subject" splits are invalid, they miss the group destination.
There's no point in looking into the subject field, if you want both cases to
go in the same folder, right ?

You're pretty close here, assuming I am guessing correctly as to what
you want.

(|
  (from "usef@devel\\.igo\\.org"
        ("subject" "Diplomacy \\(results\\|notice:\\) \\(\\w+\\)" 
         "mail.diplomacy.\\2))
  ...other splits...
  "default.split")

Use `B q' on articles after changing `nnmail-split-fancy' to see where
they are ending up.

You were right.  But... :-)

Excpeting the accidental typos, this did exactly what I asked.

Now if I wanted to put all email from usef@devel.igo.org that _didn't_
match that subject regexp in mail.diplomacy.usef, how would I do it?

Very useful tip!

(Sorry for being a PITA.  Should have remembered this case before.)

Thanks; I've now added this to the manual.
