LanX has asked for the wisdom of the Perl Monks concerning the following question:

Hi

I'm experiencing problems while upgrading to the new emacs 23. After compilation the perl error lines are not parsed in the compilation buffer.

I already asked at gnu.emacs.help ...

(see "In emacs 23 compile-mode doesn't recognize (c)perl error messages")

... but I need to know if others have the same problem before I try to report a bug.

Could anyone please try and tell me?

Cheers Rolf

UPDATE: doom just gave me the confirmation that it works form him...

    Hi

    I've sent a bugreport:

    4689: http://emacsbugs.donarmstrong.com/cgi-bin/bugreport.cgi?bug=4689 Emacs Bug Tracking System

    Here a workaround patch I found to make the regex match again:

    fixes the problem in emacs 23! 8)

    (Plz note: the WHOLE error line gets underlined now)

    UPDATE: The former patch only works for perl-mode. This is a patch for cperl-mode.el Version 6.2

    ("^[^\n]* at \\([^ ]+\\) line \\([0-9]+\\)," 1 2)
    ;; PERL 5   Blubber at FILE line XY.
    ("^[^\n]* at \\([^ ]+\\) line \\([0-9]+\\)." 1 2)
    )
