  • From #p5p:

    17:21 <@audreyt> I need to sleep.
    17:21 <@audreyt> and here is my entry:
    17:21 <@audreyt> http://perlcabal.org/~audreyt/tmp/re-engine-y2k-0.01.tar.gz
    17:21 <@audreyt> enjoy :)
    17:21 <@dmq> i think you win. :-)
    • Ha! Hilarious. Ok, so you win. But I guess I should have been more specific about what I meant.

      So to clarify, to qualify for a prize you have to implement a real functional NON-PERL (language or core) regexp engine as a plug in.

      Meaning, PCRE, the TCL 4 engine, PGE....

      So the show ain't over folks! Theres still beer to be won.

      • Hi, I wonder what are the other dimensions to that metre...are they

        * of capillary size?

        * aproximately of a size corresponding to the cross-section of a monster bavarian mug? ...

        * not specified? ... which will make us ...well very drunk...(and AdamK poorer) Actually in Madrid where I live more and more people use m when then mean m**2 especially when they talk about appartments)

        I remember seeing mentioned in Jeffreys F. book that the latest engine of Henry Spencer (possibly used in >tcl8.4) was an hybrid DFA/NFA and as such did not suffer much when fed pathological entries (of the kind that bring pure NFA engines to their knees). Last time I check it seemed the work had been left unfinished, so I'm not sure what do the tcl people actually use. Is there a special reason why you mention the tcl libraries, besides of looking for a proof of concept for your latest work.

        a few months ago I found a reference about SLK parsing and from there got to the "packrat" parsing entry in wikipedia...and became so interested that I actually started to dissect TheDamian's wonderful top-down parser generator to see what I could reuse ...and then real life and $work did not leave me a minute to spare

        do you know of that article?, actually I should check audreyt blog's more often as it was mentioned there...as "regex parsing in linear time, woow" or something like that. Is Patrick's PGE using that algorithm?...are they plans to port it to parrot or perl5? I'd like to know as the revival of madrid.pm is under way and maybe I could use that meter of beer trick of yours to lure people in doing some interesting work

        cheers and thanks for your work --stephan
        • Funny that you assume AdamK is paying for this metre of beer, too. That was only last time.
        • Is there a special reason why you mention the tcl libraries, besides of looking for a proof of concept for your latest work.

          Because of the hoo-rahing that it got from Friedl. And because to the best of my knoweldge there are only a few C regexp engines up to the job, and the Tcl engine represents the one I know of that is furthest from what Perl itself does.

          With regards to the rest, either I dont know, or we will see later. :-)

        • And this folks, is why you need to be VERY specific in challenges for prizes.

          No I'm not paying for this one :)

          But my standard was to purchase crates/cartons/slabs of "your favourite non-rediculously-expensive beer" (as in whatever you like, but don't screw me over) :) and pile those crates up until they were a metre in height.

          Of course, in retrospect I should have said "at least" or "no more than" :) So for stennie's CamelPack prize we approximated by going low and throwing in a six-pack.

          But trust me, it's
