Help with gnus-simplify-subject-fuzzy-regexp

[Igor Sosa Mayor]

Hi,

I'm using gnus as rss fetcher (using gwene, etc.). The news in some
groups have url addresses in their subjects. I want to get rid of them
and (as far as I understand) I should do it using
gnus-simplify-subject-functions.

I have this in my config:

(setq gnus-simplify-subject-fuzzy-regexp "http.*$")
(setq gnus-simplify-subject-functions
      '(gnus-simplify-subject-fuzzy))

But the subjects still have "http://etc.".

Is there any other variable or function which could maybe interfer with
this config?

Many thanks in advance!

gnus-simplify-subject-functions is not about modifing the subject
header, it is about obtaining keys for gathering loose threads.

What's the value of gnus-summary-line-format in that group? Also, maybe
first try a basic sanity check like:

(setq gnus-simplify-subject-functions (list (lambda (sub) (upcase sub))))

OK, I understand. Thanks.

Is there a way to modify subject headers (in the group summary)?

I'd guess you have to write a washing function.

You might try setting gnus-list-identifiers.

Thanks for the hint. I think I will try with a
gnus-user-format-function...

Well, gnus-list-identifiers is a "Regexp that matches list identifiers
to be removed from subject." which I thought matched exactly what you
wanted?

Yes, exactly. I will give it a try. Thanks!

Just for the record.

I achieved it with this simple function:

(defun gnus-user-format-function-j (header)
    (replace-regexp-in-string "http.*$" "" (mail-header-subject header)))
