Subject: Pattern matching on match-string groups #elisp #question
Date: Wed, 24 Feb 2021 23:11:04 -0600 [thread overview]
Message-ID: <m2h7m0d95j.fsf@gmail.com> (raw)
Can someone please tell if it is possible to use pcase-let to dissect groups (parenthesized expressions) of match-string. Here's a dumb example:
(let* ((s "lorem-foo-1-ipsum-bar-21_baz-42")
(_ (string-match "\\(foo-[0-9]+\\).*\\(bar-[0-9]+\\).*\\(baz-[0-9]+\\)" s))
(group-1 (match-string 1 s))
(group-2 (match-string 2 s))
(group-3 (match-string 3 s)))
(format "%s-%s-%s" group-1 group-2 group-3)) ;; => "foo-1-bar-21-baz-42"
Is there a more elegant way of retrieving these groups?
