Re: Dynamically inspecting Regex OP-Codes at runtime?

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

        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

[shmem]: perl -e 'warn "test$/", ^@^ '
[Eily]: well, at least it's right about warn doing the same thing as die :)
[shmem]: same with undef as last element
[msh210]: oh, good point. It's the best kind of correct
[shmem]: msh210: but I'd not call it a lie outright. That's when you do know the truth.
[msh210]: I don't have sendmail (I'm on MS Windows), so does one of you think you can report the bug?
[shmem]: msh210: 'tis about time to tell the sad truth to perl5porters - via perlbug
[msh210]: probably whoever wrote that actually knows the truth
[shmem]: msh210: you can save the perlbug text in a file and send that via your mail agent of choice
[msh210]: hm, okay, I'll try, thanks
