Getting rid of Subject: prefixes in news postings

Getting rid of Subject: prefixes in news postings

[Anders Melchiorsen]

Is there a way to make the Summary buffer chop off uninteresting parts
of Subject: lines (ie. automatic prefixes identifying mailing lists)?

The method (I forgot what it is called) I used for a mailing list
altered the file itself which is obviously not an option for news.

I also tried some of the fuzzy stuff but it seems to be only related
to sorting/threading the articles.

Probably not what you're looking for, but I use procmail rules like the
following when my mail is sorted; this takes "FVWM: " off of the subject.

:0
* ^TOfvwm@.*hpc.uh.edu
{
        :0 h
        SUBJECT=| formail -xSubject: | sed 's/FVWM: //'

        :0 fhw
        |formail -i "Subject:" -a "Subject:$SUBJECT"

        :0: 
        spool/fvwm.spool
}

[clip: procmail code]

There is also a heavy weight Subject line canoniliser procmail module
that wipes out all uninteresting words and prefixes

See pm-jasubject.rc at ftp://cs.uta.fi/pub/ssjaaa/pm-code.html

        ...

            Subject: re- Re^2: Re[32]: FW: Re: Re(15) Sv: Re[9]: -reply
                     (fwd) [fwd] <fwd> fw: [FWD:  [FWD:]]
                     -subj subj: subj: subj-
                     test
 
        This recipe standardizes any subject (like above) that has been
        replied to, to de facto format:
 
             Subject: Re: test
 
 
        You can use JA_SUBJECT_KILL to kill any additional words from the
        subject line. Eg. if you have good newsreader, you don't need the
        mailing list prefixes that some mailing lists add to the beginning
 
            Subject: [LIST-xxx] the subject here
 
        to remove that list prefix, you simply match it
 
            JA_SUBJECT_KILL = "(list-xxx|list-yyy)"
 
        Inportant: The regexp must be _all_ lowercase, because when match
        happens, the word has been converted to lowercase.

These are interesting suggestions, but the original problem was
expressly for news and not mail.

Gnus' own method uses nnmail-list-identifiers plus a related nnmail
hook, which does what the procmail solutions do.  But Anders needs
something for Summary-time hackery, on articles Gnus cannot alter.

How about a variation of

	(defun my-fix-subject ()
	  (save-restriction 
	    (message-narrow-to-headers)
	    (goto-char (point-min))
	    (if (re-search-forward "\\(Subject: Re: \\)\\[[^]]+\\] ")
		(replace-match "\\1"))))
	(add-hook 'message-setup-hook 'my-fix-subject)

For anyone interested, this solved the problem.

       (defun my-fix-subject ()
       	(save-restriction 
       	 (goto-char (point-min))
       	 (while (re-search-forward "\\[SSLUG[-A-Z]*\\][ \t]*" nil t)
       	   (replace-match ""))))
       (add-hook 'gnus-summary-prepare-hook 'my-fix-subject)
       
I am not certain that I find this solution entirely "clean". But when
I figure out a way to make it apply to just the groups which have the
problem, I can probably live with it.

Thanks!

The only solution to this that I can think of is to use a user defined
summary line specifier, as described in the last entry under
http://www.gnus.org/manual/gnus_3.html#SEC48 in the manual.

So, I tried that, but I failed (somewhat). It seems like I will have
to recode the entire subject: mangling inside that function just
because I want to mangle it a little bit further?

While I probably could get that to work (copy from gnus' source), I
would not like the approach.
