thanks for the pointers! =) I'm still hoping to find something simpler w/o needing to compile XS-modules, preferably within the core. Maybe my hack in Re^2: Is there really no @LAST_MATCH_START equivalent for named capture groups? is of help for you! Cheers Rolf	[reply]

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	[reply]

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) > I imagine you might be able to peek at a regex structure using B, that would be nice... > but you can't get at the debug messages, they're not stored, and you can't hook DEBUG_COMPILE macros 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)"` [download] The latter I don't need! =) Cheers Rolf	[reply] [d/l] [select]
