geekosaur one works for me, unless there's some corner case I'm missing (like you want the UTC of local "00:00 next tuesday") 07:59
sorear geekosaur: that's exactly what I want 08:00
turns out date --utc -d 'TZ="America/Los_Angeles" next tuesda
y' also works
apparently --utc implies TZ="UTC" unless overrided inside -d
instead of just setting the output timezone, like I expected 08:01
sorear wonders what will happen if San Diego and Los Angeles stop agreeing on what timezone to use 08:02
moritz people on twitter thinks that perl 6 is dead, because the activity on the mailing lists dropped
sorear zoneinfo doesn't even have an America/San_Diego zone :|
tell them that the mailing lists are dead, and development is done on IRC now 08:03
au "mailing list is dead, love live twitter"? j/k

/o sorear
geekosaur the one downside of that astrology outfit dropping ts lawsuit over the Olson database is we've lost that impetus to kill timezones completely 08:04
sorear apparently there are still people out there who think DST is a good idea 08:05
geekosaur it's worse than that 08:07
in the US, DST is really standard time. then there's xmas shopping time.
which is gradually being pushed closer and closer to "only during shopping silly season"

sorear hash/block disambiguation is a bit dicey in niecza; it's specced in terms of concrete syntax but niecza implements it (brokenly) at the AST level 11:04
moritz because compilers can't read minds

TimToady actually, it would probably want to recognize the ref($x) || $x idiom and refactor it to the opposite in p6 18:18
($x ~~ Stringy ?? $x.WHAT !! $x).bless or some such 18:20

phenny sorear: 15:40Z <colomon> tell sorear Looking at GLib.Process.SpawnSync for implementing run. Do you have a suggested way to get GLib into niecza's core? We could handle it the same way we do in the Gtk scripts, but I'm not sure if that's appropriate for the core....
sorear fglock: \o/!! long time no see
fglock: how's perlito?
fglock hi sorear!
I'm now working on the perl5-to-perl6 backend 19:29
perlito6 is getting very little attention these days :(
sorear phenny: tell colomon I had in mind using a reflective load, falling back to ShellQuote if glib is not available try { Type.GetType("GLib.Process,glib more-bits") } catch(...) { ... }
phenny sorear: I'll pass that on when colomon is around.
fglock sorear: I'm looking for idioms in perl6 that behave like perl5's bless(), ref(), and so on 19:32
so that I can bootstrap the perl5 compiler in a perl6 backend 19:33
that is, run perl5 "natively" in a perl6 environment 19:34
sorear that'll be a problem - there's nothing in native Perl 6 that behaves quite like bless() 19:35
fglock see my test a few lines above - it seems to work 19:36
it wraps the hash in an object
sorear I've been intending for a while to add a p5 compatibility mode to niecza's core VM, with, among other things, a p5 metaobject and bless
fglock: that's not at all how p5's bless works
p5's bless does not create objects 19:37
it changes the type of existing objects
a p5 hash is a typeless object, so you can't call methods against it
after bless(), all existing references continue to point to the same object, which now has a type
eval: package Foo; sub bar { 5 }; my $obj = { }; package main; bless $obj, 'Foo'; say $foo->bar 19:38
buubot_backup sorear: ERROR: Can't call method "say" on an undefined value at (eval 20) line 1.
sorear eval: package Foo; sub bar { 5 }; my $obj = { }; package main; bless $obj, 'Foo'; print $foo->bar
buubot_backup sorear: ERROR: Can't call method "bar" on an undefined value at (eval 20) line 1.
fglock I'm planning to use several levels of indirection to simulate that
sorear eval: package Foo; sub bar { 5 }; my $obj = { }; package main; bless $obj, 'Foo'; print $obj->bar
buubot_backup sorear: 51
19:38 snearch left
fglock it's the same problem in the javascript backend 19:39
"REF" will probably need to be a class itself
but a native p5 VM in dotnet would be very useful for perlito5 19:40
felher After i had some luck finding fossils by searching for <as>, which were then removed by TimToady++, i searched with some other regexes and found a few typos. I will fix and commit them if someone tells me if the first two really are errors and that if i fixed them correctly. 19:41

[Coke] wonders how he got a merge commit in roast. whoops. 19:46
sorear git pull?
felher: "git diff" output would have been easier to scan.
fglock eval() and double-pointers will make things slower 19:47
I hope to find a better alternative
sorear fglock: Why aren't you using ::()
?
felher sorear: okay, one moment :)
fglock ah, that works - thanks! 19:48
sorear felher: First is a typo, second is no.
not.
TimToady whoops, felher++, wrong attribution... 19:50
felher TimToady: np :) 19:51
TimToady too many f-words :)
fglock I also probably need REF-objects because ( @a.WHAT ) is the same as ( my $a = []; $a.WHAT )
so bless() will be a double-wrap 19:52
TimToady maybe we just need an SV type in P6 :/ 19:53

TimToady felher: the 'capture to an outer' in S05 is probably a fossil anyway from before we had :my 20:01
pmurias TimToady: we have a sort of SV type in niecza already which holds a p5 SV for interop purposes
phenny pmurias: 07:37Z <sorear> tell pmurias It would be nice if you could add a description of your latest p5 interop stuff to announce.v15 sometime before Tue Feb 28 08:00:00 UTC 2012
fglock not_gerd: why does it work, if the $obj argument to bless5 is not rw - I think aguments are not rw by default?
pmurias fglock: hi
fglock pmurias: hi!
TimToady pmurias: I presume that in P6 your SV is always an object, unlike in P5, and that the SV's methods will reflect many of the internal APIs of P5's SVs 20:03

au (i.e. a readonly hash value is still a mutable hash) 20:04
TimToady alas :) 20:05
felher TimToady: ah, great. Than i leave it as is for people who know what they are doing :)
pmurias TimToady: currently it tries to expose a perl6ish interface, but a raw one could be helpfull too 20:06
sorear felher: "To capture to an outer lexical variable" and "To capture an ..." mean completely different things
TimToady looks around to see if there's anyone here who knows what they're doing...
sorear felher: in the former, "an ..." is an indirect object, in the latter it is a direct object
pmurias TimToady: that's a wrong approach? 20:07
sorear the direct object of "capture" in a S05 context is always some submatch, never a variable, so the latter form is semantically wrong
TimToady pmurias: I'd guess it would be a hybrid of both
and the 6ish bits would be built on 5ish bits that might or might not be accessible 20:08
felher sorear: ah, big thanks for the explanation :)
sorear pmurias: it's a fine approach but it's not relevant here
pmurias: fglock is looking to support Perl 5 directly at the C#/NQP/Perl6 level, *NOT* by linking to libperl 20:09
pmurias sorear: i know ;) 20:10
sorear: targeting C#/libperl would make much sense 20:11
sorear fglock: the 'SimpleVariable' type in Niecza's core is conciously modelled on SV.
pmurias sorear: wouldn't
jnthn home from $trip 20:12
sorear fglock: it doesn't have all the features that are needed for P5, so a 'P5Variable' class is likely needed; both would inherit from the 'Variable' class (which already exists, and is used for TiedVariable)
Perl 6 has the nice feature that a variable can't switch between tied and not-tied after creation
