p6eval nom f9d635: OUTPUT«Bool::False␤»
Timbus nom: say ?(one(0,0) != 0)
p6eval nom f9d635: OUTPUT«Bool::False␤»
Timbus and this is the correct answer?
uh
00:00 colomon joined
Radvendii yes 00:03
because one(0,0) == 0 means one(0==0,0==0)
and one(0,0) != 0 means one(0!=0,0!=0) 00:04
both evaluate to false
it's one of those things to watch out for, that 0 != 0^0 is not the same as !(0==0^0) 00:05
Timbus i guess i was getting hung up more on the contrived construct more than anything. im sure theres a more likely case where its a problem 00:09
[Coke] "I know, I'll use Junctions!"
Radvendii [Coke]: are you saying that about yourself, or quoting it... 00:10
Timbus if you have a problem and think, 'hey maybe i should use threads', you now have two problems. if you have a problem and think 'hey maybe i should use junctions', you now have 1|2 problems 00:11

Radvendii aloha: seen [Coke]? 01:53
aloha Radvendii: [Coke] was last seen in #perl6 6 mins 30 seconds ago saying "seen pmichaud?".
Radvendii woah...
that's crazy
sorear what is?
Radvendii is that available on all channels?
sorear no
Radvendii aww...
what else does aloha do? 01:54
aloha: help
aloha Radvendii: Ask me for help about: seen, karma (say 'help <modulename>').
Radvendii aloha: help panda
aloha Radvendii: I don't know anything about 'panda'.
sorear aloha's original reason was so that bacek could tab-complete his normal greeting
Radvendii haha 01:55
really? :P
sorear "panda" wasn't even on the list
really
Radvendii aloha: help niecza
aloha Radvendii: I don't know anything about 'niecza'.
sorear what makes you think 'help niecza' will do anything?
Radvendii aloha: help karma
aloha Radvendii: Gives karma for or against a particular thing. Usage: <thing>++ # comment, <thing>-- # comment, karma <thing>, explain <thing>.
Radvendii i dont know... we're on the perl6 channel...
sorear 17:54 < aloha> Radvendii: Ask me for help about: seen, karma (say 'help <modulename>'). 01:56
Radvendii o-oh
i get it now
wait, so karma doesn't work on all channels? i thought it was an IRC thing... 01:57
[Coke] no, you need a bot to track it.
Radvendii question: How does one apply a meta-operator on a list of two arguments? 01:58
besides doing @a[0] op @a[1]
sorear Radvendii: what do you mean by a "meta-operator"? 01:59
I think you may have a term wrong - meta-operators cannot be applied to arguments
[Coke] [op] @a ?
sorear meta-operators, like »«, can only be applied to other operators
[Coke] my @a = 1,2,3; say [+] @a;

grondilu With rakudo I tried to create a module in ~/.perl6/lib, I run "use MyModule;" with no error, but then when I call a function MyModule::foo, I get a "could not find symbol MyModule::&foo". ?? 09:50
jnthn grondilu: subs are lexically scoped by default
moritz grondilu: did you write 'our sub foo'? 09:51
grondilu I tried 'our sub ...' with same result
jnthn grondilu: You need to explicitly label it "our sub ..." for that to work. Just just add "is export" to export it.
grondilu: I assume your module has a declaration "module MyModule;" at the top or some such?
moritz grondilu: did you put it into a module MyModule { .. }?
grondilu I don't want to export it

jnthn ...I can't imagine one in a while where this didn't work. :) But may as wel ask.
grondilu but why does it work only when the call is on the same line???
moritz grondilu: are you in the REPL? 09:57
grondilu doesn't know what REPL is
jnthn oh, I see
moritz the interactive Read-Evaluate-Print-Loop
grondilu yes
jnthn moritz: If you do "use Foo" then hit enter then "Foo::talk()" then it is fail.
grondilu is using "This is perl6 version 2012.01-24-g27a5dd3 built on parrot 3.11.0 revision RELEASE_3_11_0" 09:58
this is a bug, right?
moritz grondilu: it's worth mentioning that in error reports, since the interactive env is less reliable then the "normal" compiler
grondilu ok
jnthn grondilu: Yes. It's specific to the interactive mode, it seems.
moritz jnthn: new GLOBAL for each line?
jnthn moritz: Yeah, precisely. I fixed eval to share the caller's GLOBAL recently, but guess the REPL needs fixing too. 09:59

moritz it makes the current iteration the last one
10:19 tokuhirom joined
fasad no it does not make the current iteration the last one, i quote from the same page "it doesn't just mean "after we're finished with this round of the loop, we won't do any more". It really means "stop doing the loop right now, and continue after it"" 10:20
btw, it's the last but one paragraph 10:24
masak fasad: yes, it's confusing in that way. 10:30
fasad: that's why I felt the need to clarify it :) 10:31
jnthn Maybe we should call it "gtfo"
masak fasad: it helps knowing that all of those, next/redo/last, are immediate in effect.
fasad: if you want some delayed effect, you're really looking for a phaser, like END or LAST.
fasad masak: "break" from C is unambiguous (?) 10:36
one can even think of it as break(out of the loop)
10:36 abercrombie left
masak fasad: there's a reason next/redo/last are all 4 letters long. 10:41
('cus they're swearwords) :P
it's because they line up nicely, and they're supposed to be short. 10:42
break in C does too many things. in Perl 6 parlance, it does both "last" and "succeed".

raiph jnthn: right. Whiteknight, current Parrot lead dev: "6model is far superior to what Parrot provides now" 14:57
[Coke] eh. parrot has had a LOT of sunk costs. I think rakudo is going forward just fine with what parrot is providing now. 14:59
jnthn If us Rakudo devs had perfect knowledge we'd have known to build 6model a couple of years before we did, known to factor the compiler as Grammar/Actions/World instead of just Grammar/Actions, and known which Parrot primitives were badly mis-matched and not even tried to build things on them in the first place, and known what better ones should replace them.

Radvendii how so...
TimToady it's a form of deceit 18:38
doy it makes things more confusing
Radvendii cocks an eyebrow
TimToady in general, mixins are kind of a bad idea if there's a better compile-time way to do the same thing 18:39
doy you have to know you're receiving this special thing that does different things in string and boolean context
TimToady fail is supposed to be able to return interesting values of undef
Radvendii right... just like you would have to know you're recieving a list that contains a boolean and a string...
doy and you end up making mistakes like "my $err = $ret; ... <somewhere later in the code>; if ($err) { print $err }" and then get confused as to why it doesn't work 18:40
TimToady the Failure type is already there to communicate failure plus why
doy you're breaking assumptions that people will be making without thinking about them
which is a useful thing to be able to do when necessary, but really should be avoided if not

pmurias sorear: hi 18:40
Radvendii okay... 18:41
how do i handle the exception once it's thrown?
TimToady mixins are like eval or BEGIN that way; these are 'big cannons' that let you swat a fly with an asteroid
Radvendii (from 'fail')
TimToady fail doesn't throw; use die to force a throw 18:42
doy what's wrong with returning a list (or a Failure object)?
if it's not an error, those seem like better options
Radvendii i just do: Failure.new("err_message") ?
nom: say ~Failure.new("test") 18:43
TimToady you handle exceptions with try {...} or with a CATCH block

any pointers on doing that cutover? 19:56
moritz at first glance, the two are pretty similar 19:58
nqp has a bit stricter parsing rules
[Coke] no HLL::Actions or HLL::Compiler, e.g.
moritz but if you don't emit 6modelish code, you don't have to use it much
20:03 bluescreen10 left, bluescreen10 joined
pmichaud nqp can have HLL::Actions and HLL::Compiler; you just have to be sure to "import" them, I think. 20:03
diakopter ! 20:04
[Coke] (this is the file I'm trying to update) github.com/partcl/partcl-nqp/blob/...Actions.pm
pmichaud certainly NQP uses HLL::Actions and HLL::Compiler
[Coke] tries the import.
pmichaud see src/NQP/Actions.pm and src/NQP/Compiler.pm
I'm not sure that NQP supports the semi-colon-terminated declaration form anymore 20:05
might need curlies
(or that might not be the problem)
[Coke] pmichaud: there's no import in src/NQP/Actions.pm 20:06
pmichaud [Coke]: yeah, I just noticed that; so perhaps I'm mis-thinking about that.

Radvendii i thought i rememberd, but can't find, there was a syntax for anonymous arguments or the like. the way it worked was something like @a.map: {$b ~ $c} and the compiler would know that you want two variables out of @a. Was this just in my imagination?
pmichaud Radvendii: placeholder variables, perhaps/ 20:09
?
Radvendii i know i can just do @a.map: -> $b,$c {$b ~ $c}, im wondering if there's a way to implicitly declare that
pmichaud { $^b ~ $^c }
Radvendii pmichaud: what does that look like?
ah
yes

Radvendii but that's interesting... you can do patern matching in lambdas?
pmichaud Radvendii: yes. :-) 20:11
Radvendii that's quite useful...
pmichaud [Coke]: src/NQP/World.pm does "use NQPP6Regex" 20:12
PerlJam I know I asked this before, but I've since forgotten the answer ... does -> @foo[$a,$b] { ... } work to refer to the aggregate as @foo and the parts as $a and $b?
[Coke] nqp: use NQPP6Regex; class Foo is HLL::Actions {}

TimToady no, we don't canonicalize anything that is visually distinctive, and we're not sure about NFC vs NFD :)

TimToady it was a meta-utterance already 20:32

masak still, there's 3 days remaining in our contest which doesn't have a lot of sexually explicit material in it at all. 21:29
21:29 y3llow joined 21:30 pothos_ left, pothos joined
Radvendii i wish i'd heard of this earlier, nonetheless i'll get to trying them out at some point, for or not for the contest 21:31
21:32 y3llow left, y3llow joined 21:33 pothos left, pothos joined
masak yeah, it's a bit late to sign up for them this time around. 21:33
but there will be another one next Christmas, I'm sure ;)
21:34 y3llow left
Radvendii colomon: I can't find the mac executable for Niecza... 21:34
(v13)
21:34 y3llow joined
colomon Radvendii: there is no such thing. there's just a single executable 21:34
Radvendii .exe? 21:35
colomon yes
benabik mono run/Niecza.exe
Radvendii that'll run on a mac?
oh
i see
colomon mono run/Niezc.... what benabik said
benabik colomon: :-D
colomon benabik++ # one step faster than me again
benabik colomon: Normally I don't get praised for interrupting. :-D
colomon benabik: we prefer to say answering. :) 21:36
jnthn [Coke]: On the one hand, I can sorta see why it explodes. OTOH, the bit of code that does is unchanged since ages.
21:36 y3llow left 21:37 y3llow joined
Radvendii oh! is there any way to niecza a file? 21:37
colomon errr, what?
you mean run a script with niecza?
mono run/Niecza.exe mandelbrot.pl 21:38
Radvendii ah
cool
21:38 kaare_ left
Radvendii can i include the entire path to Niecza.exe and run it from anywhere? 21:39
like mono /path/to/Niecza.exe file.pl
colomon yes
[Coke] jnthn: so, is there a way to get that token without 'sploding? 21:43
jnthn [Coke]: Well, my first attempt at a patch made NQP compilation explode... :) 21:44
[Coke] WHEE! 21:45
Radvendii Is there a way to get command history on niecza? (Like, i know CPAN offers it only after you download some module or something...)
nor can I even go "back" in a line of code... 21:46
jnthn [Coke]: oh, looking again, it may just be an inverted conditional 21:47
[Coke]: gist.github.com/1685315 seems to help 21:48
Radvendii niecza: say (1,2,3)[*-2] 21:49
p6eval niecza v13-357-g9374d97: OUTPUT«2␤» 21:50
jnthn [Coke]: It passes tests so, pushing it.
dalek p: c9a8997 | jnthn++ | src/PAST/Regex.pir:
Fix what appears to be an inverted condition in the old regex engine's charlist prefix computation.
21:51 apesma left
Radvendii is there a way to use 'when{}' _without_ the break associated with it? to fall through to the other 'when's? 21:56
jnthn Radvendii: use "proceed" 21:57
Radvendii as the last statment? 21:58
well, duh :P
masak perl6: given 42 { say 1; succeed; say 2 }; say 3 21:59
p6eval niecza v13-357-g9374d97: OUTPUT«1␤3␤» 22:00
..rakudo 052cc6: OUTPUT«1␤succeed without when clause␤ in block <anon> at /tmp/Xpqe7jLGGp:1␤ in block <anon> at /tmp/Xpqe7jLGGp:1␤ in <anon> at /tmp/Xpqe7jLGGp:1␤»
..pugs b927740: OUTPUT«1␤*** No such subroutine: "&succeed"␤ at /tmp/zMqNV3st0l line 1, column 19-26␤»
masak I'm with Niecza here, but I haven't checked the spec.
if Niecza is wrong, how does one break out of a 'given' block between 'when' statements?
[Coke] if I have src/A/B.pm that isa src/D/E.pm , how can I "use" that? do I need to muck with INC? 22:02
(nqp)
tadzik :)
ww
[Coke] (use src::D::E; seems to work. ;) 22:04
Radvendii masak: no no, i want to do a when statement without breaking out
masak Radvendii: got you.
Radvendii: I just got to thinking about the above use case.
Radvendii oh 22:05
masak since 'given' is not technically a loop, you can't 'last' out of it.
so the question is, how *do* you get out of it?
(maybe the correct answer is "you should do 'for 42', duh!". I dunno.)
colomon return! 22:06
jnthn masak: leave!
colomon fly, you fools!
Radvendii :P 22:07
niecza: given 42 { when Int {say "test"; proceed}; when 42 {say "YAY!"}} 22:09
p6eval niecza v13-357-g9374d97: OUTPUT«test␤YAY!␤»
Radvendii niecza: say ?("5" but False || True) # precidence of 'but' test 22:10
p6eval niecza v13-357-g9374d97: OUTPUT«Bool::True␤» 22:11
Radvendii does niecza support :arg(value) syntax yet? 22:15
niecza: sub a(:$foo) { say $foo }; a(:foo("bar"));
p6eval niecza v13-357-g9374d97: OUTPUT«bar␤»
masak jnthn: oh! 'leave', of course. thanks :) 22:16
Radvendii niecza: sub a(:$foo) { say $foo }; a(:foo(False));
p6eval niecza v13-357-g9374d97: OUTPUT«Bool::False␤»
[Coke] jnthn: how do I get a hash-like class in nqp? 22:17
masak sorear: S04 seems pretty clear about Niecza being too permissive with 'succeed' outside 'when'. 22:18
[Coke] (before I could say "class TclArray is Hash")
Radvendii You guys wanna see meta-op overuse? gist.github.com/1685478 22:21
PerlJam Radvendii: if that works ... nice! ;) 22:22
Radvendii yup. well... in niecza at least. in theory... i haven't actually gotten all the rest of my code to work in order to test it but i've tried similar things
[Coke] "and that's why people hate perl" 22:23
22:24 estrabd joined
PerlJam It's one of those waterbed things 22:24
and ... with great power comes great responsibility
jnthn [Coke]: Ah...yeah, you can't inherit from PMCs with 6model. What does "hash-like" actually mean here? 22:26
Radvendii [Coke]: indeed. 22:27
[Coke] something like my %foo = {}; but with methods ?
er, using the right thing instead of curlies.
jnthn [Coke]: It should act like a hash, and just be able to have methods also? 22:28
[Coke] yes.
PerlJam does Associative?
[Coke] ah. if it can't inherit from a PMC, it probably doesn't matter. 22:29
(since all I'm doing in TclArray is using hll_map
ah, TclLexPad could benefit, though.
jnthn [Coke]: In that case, give it an attribute (has %!hash) and then use "is parrot_vtable_handler(...)"
22:29 shinobicl__ left
jnthn [Coke]: See src/core/NQPCapture.pm 22:30
[Coke] (and TclList for @arrays, TclString for strings...)
PerlJam [Coke]: are you updating partcl?
22:30 ksi left
Radvendii what does niecza mean by "This macro cannot be used as a function" 22:30
jnthn [Coke]: It's delegation rather than inheritance. Though in a sense that's what Parrot did before. However, in 6model this mechanism is 1 PMC lighter per object.
[Coke] PerlJam: trying to.
jnthn [Coke]: And likely performs better.
PerlJam [Coke]: cool
[Coke] jnthn: ah, sneaky. 22:31
Radvendii what's a macro... (in terms of perl6) 22:32
22:34 benabik left
PerlJam Radvendii: a macro is a routine that is executed immediately and it should return either an AST or some actual perl code that doesn't something useful 22:34
Radvendii: the AST or code is "injected" into original program at the point that the macro was called. 22:35
22:36 bkolera left
[Coke] PerlJam: "that doesn't" ? 22:37
PerlJam sorry, weird braino
...some actual perl code that *does* something useful
Radvendii okay 22:40
thanks
so why is niecza considering the last part of this line a "macro": 22:42
return [||] (%.h.keys.grep(/$c/).map: -> $p { self.legal($p, $l, :flag(False)) } );
ignore the first two characters...
niecza: sub a {True}; <a b c>.grep: {a}; 22:45
p6eval niecza v13-357-g9374d97: ( no output )
Radvendii niecza: sub a {True}; say <a b c>.grep: {a};
p6eval niecza v13-357-g9374d97: OUTPUT«a b c␤»
jnthn Time for some rest...night o/
Radvendii o/
PerlJam g'night jnthn! 22:47
Radvendii niecza hasn't implimented Proxy or eager yet?

Radvendii is there any ways to print out what you are going to print out, and what it evaluates to without typing it out twice? 23:44
oh... probably not. because it evaluates before being passed to 'say' 23:45
