Instead of running

perl script.pl ...

run something like

perl -e'
    $SIG{__WARN__} = sub {
        local ( $/, $,, $! );
        print STDERR "(W) ", @_, "\n";
    };

    do shift(@ARGV) or die("(F) $@");
' script.pl ...

Thanks Ike! `$SIG{__WARN__}` was the jigsaw piece I was looking for, though your code doesn't work and I'm not sure if you really meant a void if clause. Anyway I think the best approach is to extend or subclass diagnostics in a wayto support a "Terse" option. That must be stable. Thx! 8) Cheers Rolf	[reply] [d/l]

Fixed. By the way, diagnostics uses `$SIG{__WARN__}` too	[reply] [d/l]

> Fixed. not yet. Fatals are not reported... :) > By the way, diagnostics uses $SIG{__WARN__} too I know, but it has some functionality. I'd like to add a reference to the according diagnostic, which can be displayed in emacs after clicking. Cheers Rolf	[reply]
