simplify subject in Summary buffer

simplify subject in Summary buffer

[Denis Dzyubenko]

Hello,

Is it possible to simplify subjects in Summary buffer - remove some
parts of subjects using regexps? In documentation I found
gnus-list-identifiers, but it removes text only in the beginning of
the subject and only in the Article buffer, but I want to do the same
in the Summary. How can I do this?

When I set `gnus-list-identifiers' to "foo b" a subject "foo bar bla"
is replaced with "ar bla" in both, the summary and the article buffer.
When I use "^foo b", it's only removed in the summary buffer.

Bye, Reiner.

I see. Anyway, gnus-list-identifiers removes text only from beginning
of subject, but I need to remove text from the end. Is it possible ?

I posted a gnus-highlight file a while back that lets you do
highlighting via regexps on subject lines.  You could very easily
use it to attach a regexp it to an invisible font?

ok, I'll search for it. But it is not exactly what I want because
subjects in replies should be stripped too, but this can be done with
gnus-simplify-headers function.

It gives you the ability to do per-line changing (normally used for
highlighting, but if you use a font which is either small or invisible
or .., it could be used to hide stuff too).

I'll attach it below so you don't have to find it.  See the examples
in the variable documentation for details.

Wes,

Thanks!  I find it very useful.

Care to share your gnus-summary-highlight-expressions as an example usage?

There is a very long set of documentation for that variable...  And an
example in it:

     (require 'gnus-highlight)
     (setq gnus-summary-highlight-expressions '(
       ; turns "keyword" green.
       (".*\\(keyword\\)"                          . "green")
       ; turns entire line yellow
       (".*otherword"                              . ((face . "yellow")))
       ; turns "thirdex" blue
       (".*\\(choice1\\|choice2\\).*\\(thirdex\\)" . ((face . "blue"
                                                       match . 2)))
     )

Settings I use include bbdb mark-char marks (normally a + by default
but a mark-char insert within bbdb will replace the + by something
else, which I for important people like my boss, etc.  They then get a
line highlighted in yellow:

(setq gnus-summary-highlight-expressions
      '(
	(".*\\(teststring\\)" . ((fg . "blue2")
				 (bg . "green1")))
	; full line highlight for x-ping
	("^*"                                    . "green")
        ;  bbdb marks for author
        ;  (assumes bbdb marks in one column and From: marked in []s)
	("^......[^EOR].^[^[]*\\[\\([^]]+\\)\\]"      . ((bg . "yellow")))
	("^......[^EOR]./[^[]*\\[\\([^]]+\\)\\]"      . ((fg . "brown2")))
	("^......[^EOR].\\+[^[]*\\[\\([^]]+\\)\\]"    . "#b0e0ff")
        ; specific key word marks
	(".*\\(snmp\\)" . "#c0c0ff")
	))

I'd like to use it, too.  But it seems that `find-face' is not defined
in Emacs (at least not in the stable version).  Or do I have to load
some additional package?

It's defined in CVS HEAD as an obsolete compatibility function
(in lucid.el).

The definition used there is basically just the same as (facep NAME),
but looking at the posted code suggests that it might be better to use
(and (facep NAME) NAME) in this case.

Thank you very much.  After changing the two (find-face ...) in
gnus-highlight.el it works really nice.

Changed in my master copy.  Glad you like it.

Do note that there is also a gnus-article-highlight-expressions
variable similar to the summary buffer highlighting but works in
articles too.

EG:

	(setq gnus-treat-highlight-headers 'head)
	(setq gnus-article-highlight-expressions
	      '(
                ; highlights "keyword" in any header.
		(".*\(keyword\)" . "yellow")
                ; highlights particular source addresses
		("From:.*\(somewhere\|elsewhere\)" . "red2")
		))
