Set by TimToady on 25 November 2008.
TimToady but is essentially a positional rather than a named argument to the trait 00:00
so have to think about what using up positional args for that means long term 00:01
ruoso hmm... I see... 00:02
the trait could have a (*@tags, *%tags) signature
TimToady and then what if you want *@aliases or some such? 00:03
ruoso aliases at the "is export" side?
TimToady who knows what people will want someday?
ruoso I know... 00:04

ruoso TimToady, wasn't export(:DEFAULT) supposed to be parsed as a capture? 00:10

masak ok, here's the thing: I'd very much like fireworks in Perl 6 for this new year. 02:33
I've written half a script. it's here: gist.github.com/42176 02:34
I'm pretty sure it's reasonably correct (i.e. it should be printing fireworks)
but on my computer, it segfaults.
any idea why? is it leaky memory? do I do something out-of-bounds somewhere? 02:35

pmurias at least it's only 2 duplicated chars ;) 12:00
ruoso I'll revert my changes, and set a prototype in let
pugs_svn r24719 | pmurias++ | [mildew] fixed tiny error which broke knowhows 12:01
pmurias ruoso: you mean a let($$) ?
ruoso yeah 12:02
pmurias make test takes too long 12:03
ruoso indeed... 12:04
rewriting m0ld in p5 using SMOP xs would make it faster ;)
pmurias marginaly
pugs_svn r24720 | pmurias++ | [mildew] removed debugging statements
ruoso pmurias, gcc takes a long time also 12:05
we would gain that time
pmurias once i finish p5 integration support we could rewritte m0ld in p6 12:07
ruoso that'd be cool
I've been thinking about "is export(:DEFAULT)" 12:09
is a trait something that is callable? 12:10
pmurias traits are roles 12:12
see S12:1397
12:15 alanhaggai left
ruoso so 'is export' calls trait_auxiliary:is($export, $sub; ...) 12:18
and here we reach multis again 12:19
and more than that... we also reach semilist 12:20

azawawi on feather1
pmurias seems a ccache error 12:31
azawawi i noticed ;-) 12:32
pmurias azawawi: you use feather for development? 12:35
azawawi yeah
setting $ENV{CCACHE_DIR} has no effect on 'make' 12:37
ruoso azawawi, now *that*'s an unusual error message 12:38
azawawi deleted smop and svn up again and then make and same result... 12:41
ruoso azawawi, I doubt it to be related to smop itself 12:43
seems more like a condition in your working environment
azawawi anyone on feather1 to test it?
ruoso pmurias, I think I know I way to simplify multi 12:44
we allow the ACCEPTS code to throw a ControlExceptionPerfectSignatureMatch 12:45
azawawi not fair ;-)
ruoso I think next thing on SMOP ROADMAP is "multi" and "semilist" 12:47
this should allow us implementing "is export" correctly
azawawi i think i have an old ccache on feather1... what's your ccache --version? 12:49
2.3 here
pmurias azawawi: i don't have ccache 12:50
ruoso er... neither do I
azawawi aha we're getting somewhere
ruoso pmurias, probably we need to disable ccache in SConstruct somehw
azawawi interesting so scons is the culprit here 12:55
scons v1.0.0.r3266 on feather1 12:58
ruoso we need to disable ccache in SConstruct 12:59
azawawi take a look at this www.scons.org/wiki/ExternalTools

pmurias ruoso: what methods on an interpreter are guaranted not to recurse 13:36
ruoso pmurias, well... 13:39
continuation, goto,
loop and eval certainly recurses
azawawi, now that you have SMOP, you can just go into v6/mildew and "make test" 13:40
you probably need to 'make' in src/perl6

azawawi pmurias: so any plans to package it in cpan?
azawawi thinks Padre mildew integration 13:50
13:50 DemoFreak joined
pmurias azawawi: i could try to package mildew for cpan, i didn't do it previously as STD in not on CPAN and i didn't see much need for releasing mildew/smop ther 13:56
azawawi i already have STD.pmc in my CPAN Syntax::Highlight::Perl6
however, STD namespace collision are bound to happen... 13:57
and i stopped using the latest STD.pm for a while since it failed the parser re-use test when used inside a package. 13:59
pmurias i'm currently working on smop/p5 interop and am unlikely to do the packaging before it's finished 14:00
azawawi cool let me know when you're finished
i think STD should be released as a separate package; although STD.pmc does not qualify atm as a proper p5 package. 14:01

pasteling "japhb" at 76.191.190.8 pasted "What's the cleanest way to express this Perl 5 "pseudo-continuation" in Perl 6?" (36 lines, 1.1K) at sial.org/pbot/34162 19:08
pmurias ruoso: is there a reason for exposing SMOP::Native::int->fetch(...) instead of SMOP::Native::int::fetch(...?;
19:09 alester joined
japhb_ I hope that question makes sense ... 19:09
pmurias you could use gather/take 19:10
to create a coro
japhb_ pmurias: but I'm not "gathering" anything. That seems contrived in the same way returning a one-off sub does to emulate a continuation. 19:11
pmichaud japhb_: I think returning the closure is actually pretty clean here. 19:22
It doesn't have to be a "sub" though.
japhb_ pmichaud: In perl six, just "return {...}", right?
pmichaud yes. 19:23
and then you can invoke it directly.
I suppose there will also be a way to throw a resumable exception.
Or maybe there's a way to simply "throw" a continuation.
japhb_ pmichaud: Would you call that as $handler() or $handler.() ?
pmichaud japhb_: either would work.
or maybe there's an adverb on 'return' that means "resumable" 19:24
japhb_ pmichaud: the idea of doing a naked 'yield' is what feels most natural to me ... "throwing" a continuation sounds like the desugared version of that 19:25
pmichaud yes
japhb_ pmichaud: Is there a way to do it that allows me to say: pid_file_handler(); become_daemon; pid_file_handler(); ? 19:26
(Barring the missing parens on become_daemon(), of course) 19:27
pmichaud I know this is a silly question, but why can't become_daemon() be part of pid_file_handler? 19:31
but ultimately I'd be thinking that objects and methods would be the way to go here anyway
so that the first part and second part are just separate methods on your $handler object 19:32
japhb_ pmichaud: Oh, it certainly could ... I just wanted to separate the operations that are logically different into separate subs. The act of daemonizing, and the act of processing a PID file, are only tangentially related, and certainly daemonizing does not feel like a subordinate operation ... 19:33
Yes, I could make the pid file handling part of become_daemon(), but again, they're separate things.
19:34 smtms joined
pmichaud sure. 19:35
japhb_ pmichaud: So you're suggesting: my $pid_handler = new PidHandler(...); $pid_handler.top(); become_daemon(); $pid_handler.bottom(); END{ $pid_handler.cleanup() }
pmichaud yeah, something like that.
I do see where gather/take doesn't seem natural for 'yield' in this instance. Or maybe I'm just thinking about it wrong. 19:36
japhb_ That's certainly reasonable from the caller's point of view. I think writing PidHandler in Perl 5 would seem wordy, but perhaps not so much in Perl 6.
Yes, exactly re: gather/take v. yield 19:37
pmichaud anyway, it's a worthy question for perl6-users or perl6-language 19:38
japhb_ Fair enough. Mind if I summarize your points in my email? 19:39
pmichaud no, I don't mind. 19:41
they're just "off-the-cuff" thoughts, though.

dwhipp yes, "global" was a bad name: I was trying to use the outer-lexical 22:02
mberends is the outer scope another class? 22:03
dwhipp No. just a file-scoped thingie 22:04
