    ah yes \K not \G I keep confusing them.

    And I thought that $1 and $2 are read-only ... ah I see you use the /r flag.

    anyway, markup should be paired.

    my $wiki = '_one*'; my $expected = $wiki; $html = $wiki =~ s{ (?:^|\s) \K ([*_/]+) | ([*_/]*) (?=$|\s) } { $1 ? $1 =~ s|.|<$h{$&}>|gr : $2 =~ s|.|</$h{$&}>|gr }gexr; print $html eq $expected ? "passed" : "FAILED", "\n\n"; print $wiki, "\n\n", $expected, "\n\n", $html, "\n";

    FAILED _one* _one* <u>one</b>

    I've updated the tests in Re: wiki regex reprocessing replacement (UPDATED^2) with markup to ignore

    Funny enough, the monastery fails too :)

    FAILED
    
    _one*
    
    _one*
    
    one

    ) yes I know, wasn't explicitely tested

      Let it fail, it should be obvious in the preview.

      hehehe

        oh ... I've expected more from you, followed with a "that was fun" ... ;-(
