Not removing annoying subject parts

Not removing annoying subject parts

[Anders Melchiorsen]

In .gnus I have:

(add-hook 'nnmail-prepare-incoming-hook 'nnmail-remove-list-identifiers)
(setq nnmail-list-identifiers  '("\\[SSLUG\\]" "nagnagnag"))

to avoid "[SSLUG]" stuff from certain subject headers.


Still, in the particular mailing list, not all headers have this
removed. Some have, though. Am I doing something wrong? A cut from the 
summary buffer:

   [   8:  Kaare Rasmussen    ] [SSLUG] Re: Riva 128
   [  11:  Thomas S. Iversen  ] Re: [SSLUG] Redhat 5.1 - CD-ROM problemer - hjælp !!
   [  28:  Samuel Arvidsson   ] Re: Fetchmail...
   [   8:  Tobias Rathje      ] [SSLUG] Linux og printerservere

I am using 5.6.43 and do not really want to go on to pGnus just yet.

I think the "\\]" portion is not needed or proper, though it may work
incidentally in some cases.  Remove the "\\".  You do still need the
"\\[", of course.

I use this:

(setq nnmail-list-identifiers
      '("\\[Y2K]" "<Y2KPrep>" "PA-RKBA!" "L&J:" "PA-POL!" "\\[leatherparent]"))

It has never failed to remove things like "[Y2K]" from headers.

I now tried this but unfortunately it seems to be just the same. It
will remove the string from some posts, not from others. Weird.

What does the complete Subject line for this article look like?

If I run `(nnmail-remove-list-identifiers)' in a buffer with that line 
in it, the "[SSLUG]" is removed.  So I'm unable to reproduce this
bug.

Hmmm... to really try out that approach I entered the group with some
new messages. Some of them had it removed, some had not. I picked one
that had not and pressed Ctrl-Tab (to switch window to the article
buffer).

Pressing M-: alt entering "(nnmail-remove-list-identifiers)" placed
the cursor in the Subject line, right after the part that should be
removed (it was not removed since the buffer is read only).

So, it is only ignoring the identifier on some headers and when it
does it is actually able to find it when invoked manually. Weird!

Is there some hook or something that I may have screwed up?

Just for clarification, to be sure there isn't a misunderstanding of
what's intended, list identifier removal is done during mail
splitting, not during group entry and *Summary* generation.  The
removal is done to the messages as they exist on disc.  Any messages
picked up before you started using a list of removable identifiers
will not change.

I do realize that. It happens even with new mail (well, it is not
split that much since I have procmail splitting into groups).

Further investigation seems to suggest that it is only removed from
the first message of a batch. What appeared random might be the result 
of me importing mail several times without reading that group in between.

If you have procmail splitting into the directories, no functions will
be run (at all) to wash the files.

Oh. I have procmail splitting into spool files (one file for each
group) and Gnus tossing them into the destination groups (one file per 
message). Is that it?

But why is the nnmail-list-identifiers removed from the first article
on each import, then?

That should be ok.

I'm unable to reproduce this bug.

I figured it out. It turned out to be my fault after all :-/. I had
cut'n'pasted wrongly from the manual.

As I wrote in my initial mail, I had

  (add-hook 'nnmail-prepare-incoming-hook
    'nnmail-remove-list-identifiers)

which should, of course, have been

  (add-hook 'nnmail-prepare-incoming-header-hook
    'nnmail-remove-list-identifiers)


However, it was not until doing C-h v on nnmail-prepare-incoming-hook
that I realised that it is only called once for all imported messages
in a group (as opposed to once for each message). I do not think the
manual makes that obvious (in the washing section). When you know it,
you can deduce it from the description of
nnmail-prepare-incoming-message-hook but I never read that far before
using nnmail-prepare-incoming-hook.

Changing the description to include something like the on-line help
"The hook is run in a buffer with all the new, incoming mail" would
help, I think.

I've now made this clearer.
