in thread Dynamically inspecting Regex OP-Codes at runtime?

I'm still hoping to find something simpler w/o needing to compile XS-modules, preferably within the core.

Pipe dream if you ask me, look at http://perl5.git.perl.org/perl.git/blob#l14597 and http://perl5.git.perl.org/perl.git/blob?f=regcomp.h#l778

I imagine you might be able to peek at a regex structure using B, but you can't get at the debug messages, they're not stored, and you can't hook DEBUG_COMPILE macros

    Thx for the links but thats Chinese for me.

    I'm not a versatile C programmer and AFAIK even C gurus get depressed when diving into perlguts.

    (BTW: the first link is defunc)

    that would be nice...

    What exactly do you mean with "debug messages"? The token tree with commands like OPEN1?

    Or just message like

    anchored "1234" at 0 (checking anchored) minlen 4 Freeing REx: "(?<C>1)(?<D>2)(3)(?<A>4)"

    The latter I don't need! =)

    Cheers Rolf
