in reply to Dynamically inspecting Regex OP-Codes at runtime?

I asked in Rx-0.53/dump_regexes.pl as a module because I wanted it to simplify YAPE::Regex::Explain -- easier to extend if perl does the tokenizing

I did come accross re::engine::Hooks and Devel::RegExp, but couldn't compile either at the time ... and its all perlreguts to me, but t/re-engine-Hooks-TestDist/TestDist.xs does look promising

        forgot the :)
        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
