Heather good morning 04:26
I have some questions )
what is the progress of niecza and what exactly is nqp >_< 04:27
sorear nqp is a bootstrap layer under rakudo. fast, small, portable. 04:28
niecza was a project of mine, now abandoned. 04:29
Heather sorear but I see it's still being somehow active 04:33
diakopter Solomon Foster and Larry are maintaining it as needed
Heather sorear so rakudo is written on nqp ? 04:34
diakopter no; the kernel is written in C#; much of the library and engine are in Perl 6

04:35 preflex left
diakopter [Coke]++ 04:35
Heather diakopter I was asking about rakudo )
diakopter oh oops :D
sorear Heather: yes, rakudo is written mostly in nqp
Heather diakopter so niecza is perl6 for mono / .net?
sorear mostly? 04:36
sorear there's some rakudo-specific C too
Heather sorear I see.
sorear but that's being rewritten in or moved to nqp
04:36 preflex joined
sorear niecza uses mono / .net 04:36
diakopter diakopter-- reading fail
sorear rakudo has advanced a lot though, it will not be long before the best way to perl6 on mono is with a nqp port 04:37
Heather sorear so I can use niecza libs in my C# projects, right?
04:37 abdullah left
sorear yeah but you may need to make some small changes to the runtime, and it'll be rather dicey in any case 04:37
Heather sorear port nqp to .net? 04:38
sorear because of gather/take all Perl 6 code has to be converted to continuation passing style
which makes calling perl 6 from c# nontrivial
it's not _impossible_ but it's not supported 04:39
you'll have to do a lot of setup yourself
Heather bad
diakopter Heather: I agree with sorear; I imagine NQP will run on mono/.Net within 12 months 04:40
(and then rakudo shortly thereafter)
Heather again about nqp... 04:41
it can run on various vms ?
not parrot only?
sorear nqp runs on jvm today too, right? 04:42
diakopter its port for the JVM is mostly done
enough to bootstrap, yes
Heather where I can find implementation
diakopter not quite enough to support rakudo yet
nqp-jvm: where are you

diakopter yep
04:44 DarthGandalf left
Heather hm... 04:44
diakopter do you use the JVM? 04:45
Heather I use mono
diakopter wonders if nqp-jvm would run on IKVM on mono
04:45 preflex left
sorear niecza absolutely supports the other way though - load and use C# libraries 04:46
04:46 DarthGandalf joined, preflex joined
Heather I don't need C# libs in niecza I need niecza in C# libs 04:46
maybe I need nqp-.net 04:47
the thing: convert java code to .net is easy
diakopter Heather: several of us will be quite glad to offer any amount of help to you to write it
well... the compiler doesn't generate java code ;) it uses a bytecode emission library 04:48
Heather what about Nemerle implementation? :D
sorear Heather: how much precompilation do you need?
Heather diakopter github.com/jnthn/nqp-jvm-prep/blob...ecode.java this ? 04:49
sorear huh?
diakopter Heather: that's a small part of it
Heather: larger part: github.com/jnthn/nqp-jvm-prep/blob...mpiler.nqp 04:50
Heather il generation...
diakopter there are a few good libraries for that 04:51
Heather: sorear is asking whether you want to take Perl 6 code and convert it to .dlls 04:52
Heather diakopter yes 04:53
sorear ^
diakopter Heather: Nemerle is a quite interesting idea; because it comes with lots of tools useful to a dynamic compiler, it would provide a bunch of the hard work done for you to implement NQP 04:54
Heather diakopter so it's still being quite hard to get into 04:57
diakopter what is?
Heather diakopter compiler writing? 04:58
diakopter heh :)

sorear how is any of that surprising 08:03
diakopter niecza? or rakudo? or pugs? 08:04
sorear pugs
everything pugs has done is consistent with the ieee754 rules 08:05
p: say abs(NaN)
p6eval pugs: OUTPUT«NaN␤»
diakopter which was right here: rnp: say abs(Inf ** (0-Inf) * -1)
sorear that's eithe 0 or -0
sliiiiiight preference for 0 08:06
but they're the same in every case except division, so it doesn't matter
diakopter so should it return one(0,1(0-Inf)) ?
sorear 1 / 0 = die, 1 / (-0) = die
diakopter so should it return one(0,1/(0-Inf)) ?
er
sorear now you're just being silly
diakopter no, I typo'd 08:07
sorear it should not return a junction
is that junction thing supposed to be a good-faith proposal? :/
diakopter +/- something?
seems junctiony
sorear no, junctions are smartmatch patterns, not results of arithmetic operators 08:08
diakopter I don't see the distinction
08:09 census_ joined
moritz returning junctions from arithmetic operations violates the principle of least surprise 08:09
diakopter how would you represent a set of possible results?
sorear you return one of them arbitrarily 08:10
08:10 census left
sorear please read en.wikipedia.org/wiki/Signed_zero before complaining about -0 behavior. it's weird, it has to be weird, and it's behaving exactly as documented 08:11
sorry, I have to sleep& now
moritz diakopter: arithmetic operations on numbers don't return sets

Heather but syntax is a bit ugly with this last () :)
FROGGS_ Heather: but that's how you call/execute stuff 09:11
moritz Heather: if you want to immediately execute a block, you don't have to use a lambda for that
Heather FROGGS_ I see, though I need custom operator for it
moritz you can just say

FROGGS_ moritz: 1->Str is working too 15:35

15:36 toebu joined
FROGGS_ pmurias: is that a problem? 15:36
15:36 preflex joined
moritz I guess that 'use v5;' will have to import lots of built-ins 15:37
like a &say that uses the .Str semantics instead of .gist
FROGGS_ pmurias: my personal goal is to execute perl 5 code, I dont bother if one would be able to call methods on everything
pmurias in that particular case it's not a problem
arnsholt But to run the Perl 5 code properly, you need the proper semantics 15:38
Which, for example, means that say needs to do something different from Perl 6 say
Of course, at the moment using Perl 6 say is fine =)
pmichaud I'd guess that "use v5;" would imply switching a setting somehow. 15:39
s/a/the/
FROGGS_ arnsholt: right, right now it calls .gist, it will have to do something else in future
jnthn pmichaud: I was thinking that, then realized it's not quite that simple 'cus you expect to see outer lexicals 15:40
pmichaud that's why I said "switch a setting" and not just "start a new lexical context" :)
FROGGS_ I guess the communication between v6 and v5 blocks is easier if the v5 block only uses Perl 5 syntax but the rest is the same 15:41

pmurias when calling a 'use v6' from 'use v5' we get the modifed Perl6 language from before use v5 or the default one? 18:56
18:59 preflex joined
masak I should think the modified one. 19:00
pmurias I think so too 19:01
19:01 preflex_ left
masak because, in some sense, it's lexically nested, even with a layer of Perl 5 in-between. 19:01
19:03 preflex_ joined
sorear Whatever you do, it should be consistent with rx { '$~Regex stuff' { 'Perl 6' } } 19:03
masak aye. 19:04
and with "normal string { 'Perl 6' }"
19:04 preflex left, preflex_ is now known as preflex
pmurias having to recompile the Perl 6 setting after every change to the Perl6 grammar sucks :( 19:06
19:08 fgomez joined
masak yes, but mostly because the setting is huge and parsing is slow. 19:12
pmurias sorry, meant the Perl5 grammar 19:13
after changing the Perl 6 grammar the recompilation is necessary, after changing the Perl 5 grammar it's really annoying 19:14
sorear std: 2+2 19:17
p6eval std 86b102f: OUTPUT«ok 00:00 42m␤»
sorear that's how long it takes perl 5 to parse a roughly 100,000 line STD.pmc file. can we match that?
masak match what? 00:00? 19:18
sorear masak: yes. rounding is allowed.
er
actually you should match the irc-level latency
because I think the 00:00 counter starts *after* the parsing of STD.pmc is complete 19:19
oh, no, it does count that
my ($time, $vsz) = split(' ', `ps -o "time= vsz=" $$`);
pmurias it would be interesting to how much faster would the grammars on the jvm be compared to parrot 19:21
masak my bet is on "not disappointingly". 19:22
arnsholt Yeah, it'll be very interesting to see how Rakudo/JVM performs 19:24
19:24 preflex left, preflex_ joined 19:25 preflex_ is now known as preflex
pmurias would it be possible to allow modules to hijack the parsing? 19:28
sorear "is not-disappointingly faster" or "is not, disappointingly, faster" 19:29
pmurias: Absolutely
export something into %*LANG<MAIN>
pmurias will that get reverted on scope exit? 19:30
sorear yes
arnsholt Initial indications from NQP/JVM are that the performance improvements are not disappointing, IIRC
sorear %*LANG is contextualized by every block
supporting use COBOL; has been the goal here all along 19:31
pmurias so that should be the proper way to implement 'use v5'?
sorear yes.
diakopter arnsholt: yeah... warm jvm startup on *my* box is only 52ms... compared to perl's 1ms
[or less]
sorear STD switches to %*LANG<MAIN> at the beginning of every statement
diakopter: the reason niecza targets the clr is because warm jvm startup on *my* box was, at the time, closer to 52s 19:32
and it wasn't even swapping
wtf did they do to make startup do so much less computation 19:33
diakopter 52s !?!?
arnsholt Impressive =)
sorear I can live with 52ms
diakopter erm, that's like apples and giant peaches
TimToady apples and orangutans... 19:34

21:32 preflex left
masak a well did that? 21:33
timotimo flood the fortress! /o\
masak we shouldn't let our water storages near our code, if you ask me.
timotimo masak: did we have any big insights on how to make the constructors/deconstructors and type variables and friends work properly for our ADTs? 21:34
still kind of not sure how to implement that
masak timotimo: I think the next interesting step would be to apply jnthn's JSON-to-class code to the ADTs. 21:35
no macros yes, just BEGIN-time Perl 6 code.
and to see how far you can push the sugaring.
my guess is "pretty far".
no macros, no syntax mods. 21:36
just a functional API.
timotimo well, yeah, that's what i wanted to do. but how to do it is the question i was trying to ask
should i just mimic your class-based example for ADTs as closely as possible?
21:36 domidumont left 21:37 preflex joined
timotimo also, is it still sensible to write Tree[::A] on the lhs of the = or should it just be Tree[Str]? 21:37
er, Tree[A] i meant.
... well, that's basically a two-character-change in the source anyway 21:39
