regexp: matching a short regexp within a long regexp

regexp: matching a short regexp within a long regexp

[Patrick Drechsler]

Hi,

can somebody tell me what I'm doing wrong here? I'm trying to match a
few mailing-lists for archiving (working method was posted here[1]).

--8<------------------------schnipp------------------------->8---
;; works:
		 ((string-match "\\.gnus$\\.\\|.emacs\\.\\|.editoren$" group-plain) "Emacs")
		 ;; Unix/Linux
		 ((string-match "\\.os\\.unix\\." group-plain) "Unix")
;; DOESN'T work:
		 ((string-match "\\?suse\\?" group-plain) "Unix")
;;		 ((string-match "\\.suse\\." group-plain) "Unix")
--8<------------------------schnapp------------------------->8---

How can I match all mailing-lists which include the phrase "suse"?

I thought that one of the two mechanism (. or ?) would work like "no
matter what character shows up"...

Thankful for any pointers,

Patrick

Try "suse" or "\\bsuse\\b" see (info "(emacs)Regexps").  The first
will also match foosuseblub, the later will match things like
"foo.suse.bar" or "fasel-suse-list".  Your "\\.suse\\." requires a dot
before _and_ after "suse".

(info "(emacs)Regexps") probably is a good starting point.

Bye, Reiner.
