UncleFester6 I managed to install the updated LWP::Simple with panda and Rakudo Star-09 ok. Did you ever get that resolved? 01:22
azawawi UncleFester6: let me check it 01:23

UncleFester6 Yes - I get the error for www.google.jo ... 01:39
google.ca does not have the problem ... I will look into the problem and try to post a fix in a few days if that's OK ... 01:40
azawawi_ yeah jordan... correct google.jo => windows-1256 although shouldnt it be utf8 01:43
i guess they support older IE browsers by using that
for Farabi6 i need HTTPS + HTTP 01:44
right now im using wget in farabi6 until there is a viable p6 implementation 01:45
https is needed for github file access
UncleFester6: and thanks :) UncleFester6++ 01:46

e.g. say it was W, (1,2,3) W (4,5,6) would give (1,5),(1,6),(2,4),(2,6),(3,4),(3,5) 02:43

masak I must confess I don't really "get" #perl11. I'm not sure what kind of conversation was meant to take place there. 09:47
the parts that have been logged seem to be mostly about things like SvNV and people being rude/jerks. that is, Perl 5 stuff. :P 09:48
the one comment about Perl 6 I found was this: irclog.perlgeek.de/perl11/2012-10-14#i_6061608 09:49
perhaps we're seeing the effects of unintended-but-obvious-in-retrospect consequences here. create a channel where Perl 5 and Perl 6 people can collaborate freely, and you will find that (a) for every Perl 6 person, there are 20 Perl 5 people, and (b) most of them aren't so into Perl 6. 09:51
someone could say "so go in there and make it better!". but I don't understand what they are talking about most of the time. I guess that's how many newcomers feel about #perl6. 09:52
hoelzro masak: that it will never take off? or what? 09:54
09:55 dayangkun left
masak right. the whole comment, basically. 09:56
I wouldn't be surprised if many agree. heck, I may agree, too. (though why exactly 10 years? why not 5 or 20?) 09:57
09:58 leont joined
masak but it feels a weird thing to bring up on a channel for p5/p6 collaboration. maybe it would feel *less* weird if the rest of the backlog over there was actually about p5/p6 collaboration. 09:58

nwc10 question about the IRC logger - if I understand it correctly, it only links to channels on days where there is activity
is there a way to make it only show links where there is *actual* activity - ie not just joins and parts? 10:04
masak not that I know. 10:05

masak brrt: there is a story about a programming language designer who shocked his PhD students by putting linked lists in his lexpads instead of hash tables. guess what: his way was faster. 10:29
brrt masak: seriously? that is somewhat hilarious 10:30
masak s/in his/in the implementation of his/
brrt i had a toy implementation of scheme that used linked lists :-p back when i didn't know how hash tables work
masak if not the Oberon language, then some language from that family. and I don't think it was Wirth, but someone else.
moritz if a lexpad is usually very small, I can imagine that 10:31
brrt a lexpad is usually very small
moritz especially if you compile symbol lookups to the pointers
r: say CORE::.keys.elems
p6eval rakudo 0e866a: OUTPUT«425␤»
brrt 10 variables are a lot for a single routine
and, if as moritz say, you use symbols rather than strings 10:32
things get simpler still 10:33
masak moritz: well, compiling to pointers is just common sense, I think. but there's no way to remove the "two lexpads up" cost at runtime, in a language where you have not only static lexpdads but runtime lexpads, too. that is, most languages.
brrt also, you might as well put a simple array, augmenting the lexpad is rare
i.e. the cases where a compiler cannot predict the number of fields the lexpad has to take 10:34
masak but yes, the cost of the linked list happens mostly during compilation.
maybe the extra lookup cost of the linked list is much smaller than the setup cost of the hash.

pmurias: Note that the return can be from several nested blocks. 14:09
If you're compiling each QAST::Block to a JavaScript function, you need to make sure you return from the right one
pmurias I'm aware of that
jnthn OK
pmurias but I don't have a good solution for that, I'm afraid I'll have to use exceptions for that 14:10

[Coke] jnthn: is there a way to augment nqp classes like String? 14:37
jnthn [Coke]: There is no NQP class String
[Coke] Figured I'd try that out rather than try to get the HLL mapping working.
jnthn [Coke]: You're confusing Parrot's type system and NQPs.
[Coke] oh, is that String the parrot String? 14:38
jnthn They don't intersect.
Right.
NQP still uses bits of both.
[Coke] nqp: say(String.WHAT);

14:38 cosimo joined, hash_table joined, havenn joined
jnthn Rakudo doesn't use hll mapping or expose Parrot types, fwiw. 14:38
Well, it does for its custom lexpad I guess. 14:39
But not for anything "user facing"
[Coke] wonders if he can augment parrot types from nqp, then. Or get parrot subclasses instead of nqp subclasses, since they don't seem to be equivalent.
(though, to be fair, I haven't tried to distill my core issue of not being able to do an HLL mapping down to a simple test file.) 14:40
jnthn [Coke]: It really depends what your goals are. If your goal is "a compiler that targets Parrot" you could go that way and it should mostly work out. If your goal is "a compiler that will, without too many changes, work on anything else that NQP lets you target in the future", then avoiding depending on Parrot's HLL mapping is probably for the best. 14:43
[Coke] My goal was "get partcl working again with the minimum amount of effort". :) 14:46

japhb jnthn, I haven't done my backlogging yet, but just looking at where you highlighted me ... Niecza has internal support for a "dualvar", and then exposes that through role Niecza::Dualvar, so class IntStr is Int does Niecza::Dualvar. Given that Kernel.cs says "// Truly vile hack to make dualvars work.", I was hoping to avoid that kind of invasive work in Rakudo. So first I tried 'class IntStr is Int is Str { has $!string handles < Str gis 14:48
phenny japhb: 06:52Z <jnthn> tell japhb If you don't backlog, see irclog.perlgeek.de/perl6/2012-10-25#i_6097300 :)
japhb t >; has $!value handles *; }' but that resulted in reliable segfaults. So then I tried it again with *just* delegation, got the dispatch failures, and golfed my way to what I posted last night. So I'm stuck at the moment.
14:49 havenn left
jnthn japhb: But if you inherit from Int and Str you already have something capable of storing both an int and a str. 14:49
Well, apart from it's not an int, it's a bigint thingy
japhb: 6model is capable of such things, but currently only from the C API to it.
14:49 xinming left
japhb Done entirely at the Perl 6 level, how would I see the attributes of Int and Str where I would store the respective values? Or are you saying that I have to do 6model hackery to get at them? 14:51
s/Perl 6/NQP and Perl 6/
14:51 Exodist left 14:53 Exodist joined
jnthn japhb: I'm saying that currently, we only expose ops like nqp::p6box_n(...), for example 14:53
It internally does an allocate, initialize and set_num
japhb following you so far 14:54
jnthn We don't have ops that use a single object to box two primitive types.
14:54 mucker left
jnthn It's not that we need to do any low-level 6model hackery. It supports it well enough already, it's just that bit of functionality isn't exposed in any way to NQP or Rakudo space. 14:54
japhb OK, it sounds like you're suggesting writing said double-primitive boxing ops, and basically having the equivalent of Niecza's low-level dualvar, yes? 14:55
But perhaps less painful because 6model is designed to handle that level of crazy. 14:56
jnthn yes, write the ops to construct these kinds of thing.
japhb OK, guess it's time to learn 6model a little more thoroughly. :-) 14:57
japhb had held out some home that Perl 6 was powerful enough to do that all in "user space", so to speak, but perhaps I was pushing it a bit too far.
*hope 14:58
pmurias what is a dualvar?
[Coke] jnthn: but you're right. if I stop trying to target parrot through nqp and just target nqp, I'll no doubt have an easier time of it.
brrt a scalar that holds both a string and a number at the same time 14:59
in p5, you have a 'use dualvar'; which allows you to manipulate this
(a p5 scalar always holds both, but they are supposed to be in sync) 15:00
pmurias do we have them in Perl6?
japhb pmurias: yes ... the result of the val() sub, which I'm trying to implement in Rakudo 15:01
pmurias found it in the spec 15:04
japhb Well, I guess val() is a very specific subset of the general dualvar concept, but still, the basic functionality is required.

however, this does not explain why it is "fare thee", and not "fare thyself"
maybe it's one of those things like "Just look at you!" 17:37
masak maybe.
TimToady where it's objectifying the 2nd person to make it seems like someone else
or "F*ck you!" and such 17:38
or maybe it's using "you" as a referent to a 3rd-person notion in the speaker's mind, pragmatically "I'm not really speaking to you, but about you." 17:39

TimToady so even though the form of the verb seems to indicate a command to the hearer, it's really more like a Whatever for the subject of the sentence 17:41

masak it would seem to me :ex is passed down to subrules.
or something.
jnthn I thought it was meant to produce all the possible ways it can match.
masak aye.
flussence am I imagining things, or did we have an :all at one point that would've worked that way? 20:26

LordVorp I'm on a forum that often has attached files with names that look like: "Sample (10).tos". When I click Download, I get a file named "Sample %2810%29.tos". Is there a switch or setting that will make these come down w/o escapes? 20:33

20:57 hash_table left
jnthn japhb: To explain what's needed... 20:57
masak japhb: I know how that feels. I've been wanting macros for years.
jnthn Boxing a primitive involves two steps:
japhb is listening
masak, I bet!
jnthn 1) allocate
2) store the primitive type inside of the object 20:58
Int is a little bit different because it's really a big integer, but it's basically the same approach. 20:59
For example, the op taht boxes an int is:
PMC *type = Rakudo_types_int_get();
$1 = REPR(type)->allocate(interp, STABLE(type));
REPR($1)->box_funcs->set_int(interp, STABLE($1), OBJECT_BODY($1), $2);
If you're coming from a native integer 21:00
It occurs to me the easiest way to get what you want is really just to produce the FooStr in the same way you'd produce a Foo 21:01
And then write just one op that is something that sets the thing's string likeness
21:01 spanner joined
jnthn So it takes an existing object and a string and just calls the set_str on the boxing API. 21:02
Plus do a write-barrier in the op.
japhb Is there already a slot to store the string into?
jnthn If you inherit from Str also then yes. 21:03
21:04 skids left
jnthn To illustrate what's going on: 21:06
japhb jnthn, Am I correct in assuming that by '6model.h', you actually meant 'sixmodelobject.h'?
jnthn r: class SpecialStr { has str $!value is box_target; multi method gist(SpecialStr:D:) { self.Str() }; method Str() { self } }; my $x = nqp::box_s('blah', SpecialStr); say $x.WHAT; say $x;
p6eval rakudo 0e866a: OUTPUT«SpecialStr()␤blah␤»
japhb still listening
jnthn japhb: uh, yes, sorry :)
Str is declared something like this. It's native str is marked with the "box_target" trait. 21:07
This means that if you use the type to box a native string, or you want to get a native string out of it, it will look at that slot.
21:08 benabik left
japhb no problem. BTW, I note that the only differences between the copies in Rakudo's src/binder/ and NQP's src/6model/ is the write barriers and the 3 typedefs right under 'Dynamic representation registration.' in the NQP version. Is that just unintentional skew, or intended difference? 21:08
jnthn Unintentional skew
japhb Ah, OK
jnthn Surprising though because normally things explode very quickly if they are out of sync 21:09
Well, actually, the dynamic representation registration stuff is used nowhere in Rakudo
But it doesn't harm to have it. Feel free to sync them. (NQP one is latest.)
japhb Okie dokie
So I guess my next question is, can there be multiple box_targets, as long as they have different native types? 21:10
jnthn Yes 21:11
japhb \o/
jnthn And it's not just about the 3 core native types
japhb Oh yeah, my job just got way easier
jnthn Any inlineable REPR can kinda have one too
Which is why the libtommath big int data structure can be inlined straight into the body of a Perl 6 Int.
japhb jnthn++ # Internal APIs that don't suck
excellent
jnthn Rather than needing another level of indirection.
In the end this kinda thing is how we'll get things like packed arrays of compact structs. 21:12
jnthn waves hands a bit :)
