jeremyb_ is perl 6 ever going to happen? 04:19
jeremyb_ hides
allbery_b we killed larry and ate him, so no :)
jeremyb_ didn't know this channel existed
hehe
jeremyb_ waves to agentzh
Tene jeremyb_: it already does, for some definitions of "happen" 04:22
I've used it for a few personal and work projects. 04:23
jeremyb_ actually doesn't use perl much and was just kidding
jeremyb_ has heard good things about 6 but doesn't remember what 04:24
Tene: using the haskell implementation? 04:25
Tene jeremyb_: haskell and parrot
I've used both. 04:26
jeremyb_ ewwww, darcs
Tene Who uses darcs? 04:27
jeremyb_ pugscode.org
Tene Oh, I've never looked at the darcs mirror 'cos I've never been interested in darcs. 04:28
I've been tracking pugs through git-svn
jeremyb_ has had good experiences with git-svn
jeremyb_ wonders who Alex is
< sproingie> i think perl6 killed off tie... at least i hope it did 04:33
platypus Isn't there now a lisp implementation? 04:37
Tene platypus: yes, kp6 has a lisp backend now
jeremyb_ implementation or flavor/variant?
Tene It's been developed over the past couple of weeks or so (I think) and is now about up to the level of the perl5 backend. 04:38
I know that it runs at least on sbcl
I'm not lispy enough to know if it also runs on others or not.

agentzh hi, a p5 question: how to release a very p5 hash immediately? p5's GC is very slow for a hash as big as several GB. 07:15
*very big
sorry if it's a bit OT :P 07:16
jql p5 gc doesn't do anything at all after undef %hash;
there's no compacting/copying gc to trigger
it immediately frees, and that's it. :(
agentzh jql: thanks :) 07:17
jql: trying now
07:27 Aankhen`` joined 07:33 cognominal_ left
Aankhen`` Tene: Re: the Lisp backend for KP6, it's not really up to the level of the Perl 5 backend yet since it doesn't support objects, for one. 07:35
As far as implementations go, it doesn't use anything SBCL-specific, so in theory it ought to work on any conforming implementation. 07:36
07:37 drrho joined
agentzh Aankhen``: how about the list-backend's performance? 07:45
jql: it doesn't work for us. undef %hash still takes 20 min to complete, it seems. 07:46
jql wow, that's an impressive hash you have
Aankhen`` agentzh: I'm not really sure, never bothered to measure it. The only metric I have is from a while back, when avar measured a compiled test performance and found it only slightly slower than the equivalent Perl 5 code. 07:47
s/test/test's/ 07:48
agentzh Aankhen``: okay :)
Aankhen`` That was before support for a lot of things was added though, including formal sub arguments, all of which does inevitably add overhead. 07:49
agentzh *nod*
Aankhen`` Still, I'd expect it to be pretty durned fast once compiled.
agentzh heh
Aankhen`` The best part is, so far I've just been focusing on clarity.
Nothing about KP6-CL takes performance into account.
agentzh fair enough :) 07:50
Aankhen`` Oh yeah, it's also missing a lot of control structures, since I wasn't very interested in them and no one (except fax) was either. :-P 07:51
Aankhen`` decides to go for the low-hanging fruit.
s/no one/no one else/ 07:52
agentzh hehe 07:53
Aankhen`` Argh, I need to fix the ::Lookup/::Index thing first. 07:54
agentzh Aankhen``++
Aankhen`` What brought that on? 07:55
agentzh i hope i am able to hack on kp6 as well :P
Aankhen`` Ah, kewl.
agentzh $work forces me to do XUL hacking :)
Aankhen`` agentzh++ # it's the thought that counts!
agentzh hehe 07:56
moritz_ did anybody adopt Pugs::Compiler::Rule to the new regex syntax?

Aankhen`` Sweet.
Mine is the same except it has 2 GB of RAM.
moritz_ it's a fujitsu siemens, and I hope it will work under debian ;)
Aankhen`` Heh. 08:05
Mine's a Sony VAIO running Vista. :-)
moritz_ mine will be delivered with Vista, but that's not going to last ;)
Aankhen`` grins.

moritz_ if so I'll sue them
Aankhen`` Good luck.
moritz_ Germany has pretty good laws for customer protection
Aankhen`` Ah. 08:07
moritz_ and the EU is trying to break the $MS monopoly (with not much success, but at least they try)
Aankhen`` I know. 08:08
moritz_ and they fined $MS 0.5Bn € ;)
Aankhen`` They were barking up the wrong tree with regards to the search thing, though.

15:44 arrowax joined

(when (null (find-package 'kp6-lisp))

Aankhen`` Anything!
avar maybe this is causing trouble?
Aankhen`` It shouldn't be trying to call MAIN::MAIN.
Nope, that works fine for me.
avar when does it work fine for you? when you create executables with sbcl? because that's the issue with the tests 15:49
Aankhen`` Oh, wait.
The test script always tries to call MAIN::MAIN?
avar I can run it fine as -lisp | sbcl

Aankhen`` Unless I'm missing it, perlrun doesn't seem to mention status codes. 15:54

uh, wrapper for doing that

if I rewrote everything to use method calls what would break 17:29

Aankhen`` Why is ::Module commented out in Ast.pm? 17:49
avar Aankhen``: I think we can definetely piggy-back on CLOS
17:49 Kattana left
avar if it's the 'use Foo' thing then probably because it broke everything 17:49
Aankhen`` `class Module { ... }` is commented out. 17:50
And I don't think we can piggy-back on CLOS.
17:50 japhb left
avar why? 17:51
You don't have to use all of clos..
Aankhen`` Uh.
We're going to be using CLOS the same way we're using it right now, if that's what you meant.
In the end it's going to be CLOS objects.
avar I was just thinking of using generics to handle dispatch instead of something custom, mainly 17:52
Aankhen`` But, for example, we're not going to create a new CLOS class for each Perl 6 class, or use generic functions.
avar well we'll see 17:54
pmurias Aankhen``: ::Module is comented out because it was replaced by CompUnit 17:57
Aankhen`` pmurias: Ah.
So ::CompUnit should be generating a new package?
(Assuming it doesn't exist already.)
pmurias yes
well a new module, or class or role 17:58
Aankhen`` Okay. 18:00

r18320 | Aankhen++ | * ::CompUnit creates a new package as appropriate using KP6-ENSURE-PACKAGE.
r18320 | Aankhen++ | * KP6-ADD-PROGRAM should take &BODY BODY rather than a single PROGRAM form.
r18320 | Aankhen++ | * KP6-LISP-USER::MAIN now takes INTERPRETER and STANDALONE keyword arguments.
r18320 | Aankhen++ | * INTERPRETER indicates the KP6-INTERPRETER object to use, defaulting to a fresh instance of KP6-INTERPRETER.
r18320 | Aankhen++ | * STANDALONE indicates whether the function should take over responsibility for errors and the normal end of the program.
r18320 | Aankhen++ | * regenerated EmitLisp.pm

TimToady avar: I think I want to play with TRE for my lexer engine for STD 19:33
[particle] TRE?
TimToady laurikari.net/tre// 19:34
lambdabot Title: TRE home page
TimToady there are Perl and Haskell bindings
so either I need to "use v5" to get the re::engine bindings, or get someone to hook up the Haskell bindings to pugs 19:35
avar note that re::engine only works on 5.10 19:36
tre is posix compatable so any posix regex binding will do
TimToady well, I've got 5.9.mumble installed
avar yeah 5.9.5/5.10
TimToady but tre does tagged transitions efficiently, I think
so I can pull out longest tokens that include subrule matches 19:37
but when I cpanp install it, it tells me that cpans's re is out of date :( 19:38
avar can you paste the error? 19:39
19:39 barney left
TimToady [ERROR] The core Perl 5.009005 module 're' (0.08) is more recent than the latest release on CPAN (0.05). Aborting install. 19:39
though for the STD prototype, I'd probably just as soon use the Haskell version if it were hooked up, since I'm targeting pugs right now. 19:44
but every time I argue with ghc I lose... :/
avar that's cpanp -i re::engine::TRE ? 19:49
TimToady no -, but yes 19:50
19:50 chris2 left
TimToady cpanp running under 5.9.5 19:50
19:53 dduncan joined
avar use -f ? 19:57
TimToady doesn't understand -f 20:01
trying with cpan instead 20:02
bleh, TRE.xs: In function ‘TRE_comp’: 20:04
TRE.xs:26: error: ‘RXf_SPLIT’ undeclared (first use in this function)
20:05 jisom left
TimToady is 5.9.5 not sufficiently 5.10ish? 20:05
avar yes, your 5.9.5 just isn't recent enough, there were a lot of changes while it was called .5, you need to upgrade
TimToady thanks 20:06
20:06 jferrero joined
avar anyway I still don't quite see the point to be honest:) But then again I haven't studied tre so closely 20:06
but I think you mainly win on patterns not going exponential and not crapping out on some pathological patterns
TimToady the crucial part is knowing which part of the pattern matched 20:08
pasteling "TimToady" at 71.139.11.229 pasted "sample lexer for expect_term" (923 lines, 27.4K) at sial.org/pbot/27951 20:10
TimToady I need to be able to run the pattern above and know which STD rules were traversed to get there
20:10 blindfish left
TimToady I think TRE will give me that 20:11
avar I didn't see anything like that in its manual, it has an interface for that? 20:12
TimToady it does substr captures
as described in this paper by the same person: laurikari.net/ville/spire2000-tnfa.ps 20:13
avar I don't think that's in the re::engine::TRE interface though 20:14
TimToady if you can pull out $1, $2, as documented, it can
asssuming you haven't put a hard-coded limit in 20:15
avar that's to get the parts of the string that were matched, but as I understand it you want to know the parts of the regex that were matched to get there right? 20:16
TimToady see example--as long as all the parens get their own number, I can derive that
avar ah
TimToady also asssuming that the -> foo notation turns into ()
in the long run I'd like to rewrite TRE or something like it in Perl 6 20:19
because it's almost exactly what I was thinking of with the revisions of S05 to define longest token matching 20:20
if we integrate it well, nobody ever has to write their own lexer again. 20:21
that's the goal of all this autolex stuff I've been working on
