Re: The new Perl 6 compiler pumpking
Sorry if this is a repeat, but I didn't get my own mail back, so I think I may have had sending problems. On Aug-09, Patrick R.

But I think he and I are in agreement that we'd like to have a grammar engine substantially completed (at least to the level of being able to bootstrap a Perl 6 compiler) within the next 3-4 months. I have one of those too, in languages/regex. The parser is crap, and the implementation of the translation has probably seen a few too many rounds of evolution, but I believe the output is the Right Way To Do It and is relatively easy to extend to support the rest of the Perl6 features. Okay, maybe it's only One Of The Right Ways To Do It. I'd be interested in knowing what your output looks like, and encourage you -- if it's close enough -- to steal my rewrite rules wholesale. (Actually, the parser used in the languages/perl6 directory is pretty nice; the one in languages/regex that I use for testing is crap.) See languages/regex/docs/regex.pod for an introductory document on this style of rule implementation. I wrote it a while back, and have added at least one more fundamental concept to what I laid out there, but it should be more or less valid nonetheless. I left off working on it long ago to concentrate on beefing up the Perl6 compiler enough to make it an interesting host language, but recently I've (locally) added match objects and a parse tree. I have rules, but I was holding off grammars until someone else braver and smarter than I beat on Parrot's object support a bit more. The various cuts are straightforward additions that I've already sketched out, and everything else is gravy. Heh. And I'm really wishing I had picked Jako or one of the other languages/* as a sample host language...

Welcome Patrick! What's your plan of attack? Hello, Leon and everyone else. I'm glad to be aboard, and hope you'll all bear with me as we get things started. The plan of attack is that we're going to design and build a Perl 6 grammar/rules engine first, and simultaneously with that we'll be solidifying the (default) Perl 6 grammar itself. Since many parts of Perl 6 are still changing, we'll likely take a snapshot of the current design as our immediate target, but keep an eye on perl6-language and other forums to make sure we don't paint ourselves into an implementation corner. Luke Palmer and I started work on the grammar engine this past week. It's a wee bit too early in the process for us to be making any promises about when people might be seeing releases and the like. But I think he and I are in agreement that we'd like to have a grammar engine substantially completed (at least to the level of being able to bootstrap a Perl 6 compiler) within the next 3-4 months. It'll take another few days for Luke and I to get our detailed plans together. We will likely want to create a separate mailing list for discussions of the compiler and grammer engines, and leave perl6-internals with a parrot focus (or possibly rename it as well). Overall I'd like to see us release a good implementation of the basic Perl 6 compiler engine within the next 12 months or so. But we'll have a much better idea of timelines as we start to work on the grammar engine, and as we see how Parrot matures in the next few months, and I'll be sending questions and status reports to the lists every couple of weeks so that people can gauge progress. I'm a strong believer in release-early, release-often and in making items available for rapid feedback. Pm
The new Perl 6 compiler pumpking
There's not been a big public announcement, so it's time to change that. I'd like everyone to give a welcome to Patrick Michaud, who's volunteered to officially take charge of getting the Perl 6 compiler module written. I've put in yet another nudge to get the parrot-compilers list started, and get the perl6-internals list renamed to parrot-internals (which is what it really is) so we can get things properly sorted out, as I expect Patrick will be digging into the fun stuff pretty darn soon. -- Dan --it's like this--- Dan Sugalski even samurai [EMAIL PROTECTED] have teddy bears and even teddy bears get drunk
