Subject: bug#19208: replace-match unhelpful error message
Date: Fri, 28 Nov 2014 17:00:15 +0000 [thread overview]
Message-ID: <87r3wn5kgw.fsf@newcastle.ac.uk> (raw)
Occurs in Emacs 24.3 and trunk
Running this code in *scratch* buffer
(progn
(goto-char (point-min))
(re-search-forward "This")
(replace-match "That" nil nil nil))
Now undo and run this code
(progn
(goto-char (point-min))
(re-search-forward "This")
(replace-match "That" nil nil nil 1))
This causes the following error.
progn: Args out of range: -1, -1
The error is caused because I have asked for a subexp that doesn't exist in
the regexp. A programmer error for sure, but the Args out of range error seems
rather unfriendly to me, especially as I have no idea where the -1, or
-1 has come from.
"Attempt to replace regexp subexpression that doesn't exist", for
example, would be nicer.
