meppl good night 01:57
akreal good morning, meppl! :) 02:25
akreal is away: Отошёл. 02:57
ispy_ so does perl6 support complex-data structures just yet? 03:48
PerlJam Perl 6 does. But it sounds more like you're asking about a particular implementation. :) 04:22
ispy_ I want to know the equiv of @{ $struct{key} } 04:24
allbery_b @struct<key> I think 04:27
lambdabot Unknown command, try @list
PerlJam ispy_: you mean %hash<key> ? 04:28
Khisanth heh
allbery_b <- been not thinking p6ish for too long, sigh
ispy_ ahh... 04:31
hmm... @hash<key> doesn't work either... 04:33
allbery_b no, it won't 04:34
PerlJam %hash<key> # note the punctuation. 04:35
allbery_b hence my "not thinking p6ish for too long":
I think if %struct<key> contains an array then you get it
ispy_ but %hash<key> returns the array in scalar context.
allbery_b unlike p5 where yu get an arrayref you need to manually deref
PerlJam ispy_: not if you use it in a list/array context.
allbery_b ==PerlJam 04:36
p6 is smarter about such things
PerlJam ispy_: if you want to force the listiness, you could surround it in @()
ispy_ that's what I figured, but it doesn't seem that way.
ok.
that's what I was wondering, if p6 had the equiv. of @{
so that's it? @(
allbery_b yes 04:39
it's a function-like thing now instead of special syntax
ispy_ I can hang with that. 04:40
:)
it's consistant.
I was sorta thinking p6 had dynamic ref determination but, oh well :)
PerlJam "dynamic ref determination"? 04:41
allbery_b it does, usually, if I understand you correctly
PerlJam it does the right thing when used in the right context and you get the option to force a context.
allbery_b that said, some implementations may not support it properly yet
p6 is still prerelease and in active development, after all
PerlJam for instance, %hash<key>[0..6] should work fine.
no need for @() there 04:42
ispy_ right.
also %hash<key>.[0] works too... 04:43
which is nice.
I'm really into p6 right now for some reason...
just started fooling around with it last week.
ludan hi 11:04
moritz_ hi all, good localtime() ;) 11:05
Aankhen`` waves at moritz_ and ludan. 11:23
pmurias waves at Aankhen``,moritz_ and ludan 12:00
elmex waves at noone
Aankhen`` surreptitiously waves at pmurias and elmex too. 12:01
Yay, lots of waving action.
pmurias Aankhen``: if it's nothing private why did you decide it will be better if you don't work on kp6-lisp? 13:30
Aankhen`` pmurias: Basically, because I felt the way I work is very inappropriate for KP6. KP6 needs the "get as much done as you can right now" style whereas I'm obsessed with getting it done right and complete straight off the bat. 13:59
(Which is naturally pretty much impossible, so I move at a glacial pace.) 14:00
pmurias Aankhen``: ok 14:01
pmurias pugs: my @array = [];say @array.perl; 17:35
exp_evalbot OUTPUT[[[],]␤]
moritz_ that looks a bit buggy 17:36
masak it's an array of an array
that shouldn't happen, right? 17:37
moritz_ masak: that would be ([],) or plain [],
Tene pugs: my @array = 1; say @array.perl;
exp_evalbot OUTPUT[[1,]␤]
Tene pugs: my @array = (); say @array.perl;
exp_evalbot OUTPUT[[]␤]
Tene pugs: my @array := []; say @array.perl;
exp_evalbot OUTPUT[[[],]␤]
moritz_ pugs: () ~~ [] ?? say "yes" !! say "no" ; 17:38
exp_evalbot OUTPUT[yes␤]
masak moritz_: I thought parentheses were only used for grouping in perl 6
moritz_ masak: yes, that's why ([],) and [], are the same thing
masak moritz_: yes
I suspect we're agreeing violently
moritz_: the output was `[[],]`, which looks like an array of an (empty) array to me 17:39
Aankhen`` Needs moar violence. 17:40
masak actually, pugs probably needs more tender care :)
Tene masak: I think that's accurate... what would you expect this to do: 17:41
pugs: my @array = ([],); say @array.perl;
exp_evalbot OUTPUT[[[],]␤]
masak hm 17:42
Tene: still, in your example it feels like you're talking about two arrays
not pecause of the () but because of the ,
s/p/b/
Tene mugs my @a = 1,2; my @b = @a; @a.perl 17:43
pugs: my @a = 1,2; my @b = @a; @a.perl
exp_evalbot RESULT["[1, 2]"␤]
moritz_ we need more mugs!
masak Tene: my intuition agrees with that last one
masak but not with 17:44
masak pugs @a = []; @a.perl 17:44
pugs: @a = []; @a.perl
exp_evalbot OUTPUT[*** ␤ Unexpected " ="␤ expecting "::"␤ Variable "@a" requires predeclaration or explicit package name␤ at /tmp/NNtOrcbois line 1, column 3␤]
Tene pugs: my @a = 1,2; my @b = [@a]; @a.perl
exp_evalbot RESULT["[1, 2]"␤]
masak pugs: my @a = []; @a.perl
exp_evalbot RESULT["[[],]"␤]
Tene pugs: my @a = 1,2; my @b = [@a]; say @a.perl; 17:45
exp_evalbot OUTPUT[[1, 2]␤]
Tene pugs: my @a = 1,2; my @b = ([@a],); say @a.perl;
exp_evalbot OUTPUT[[1, 2]␤]
pugs_svn r19005 | moritz++ | [evalbot] no newline in RESULT[...]
Tene Hm.
masak I read `@a = []` as 'assign an empty array to @a', not as 'assign an empty array to the first element of @a' 17:46
moritz_++
Tene masak: how do you read: @a = 1
?
masak that newline really was unnecessary
Tene: that's different 17:47
pmurias masak: kp6 used to treat @a = [] as @a = () but it was changed
Tene masak: not as I understand it...
[] is different from ()
masak hm
if we were talking about perl 5, I'd definitely agree
but I've had to relearn some things about arrays that perl 6 does 17:48
I thought this was one of them
pugs_svn r19006 | pmurias++ | [kp6] the multis are back
Tene However, I would not pbe surprised if pugs has this one case wrong.
I can't get it to do the same thing with: @a = [@b]; 17:49
pugs: my @a = [1,2]; print @a.perl;
exp_evalbot OUTPUT[[[1, 2],]]
Tene pugs: my @a = 1,2; my @b = [@a]; say @b.perl;
exp_evalbot OUTPUT[[[1, 2],]␤]
Tene ... helps if I print the right array. ><
Yes, it does the same thing with =[@] 17:50
masak Tene: my rationale would go something like this: in perl 6, every array is really a reference (as in perl 5's backslash). assigning [] to an array variable means giving it a reference to a new empty array
...whereas assigning 1 to it would mean first packing it into an array and then assigning the reference for that 17:51
Tene Hm.
masak: but it's already in array context because you're assigning to an array.
consider:
my @a = 1, 2; my $b = [@a]; print $b; 17:52
my @a = 1, 2; my $b = [@a]; print $b.perl;
pugs: my @a = 1, 2; my $b = [@a]; print $b.perl;
exp_evalbot OUTPUT[[1, 2]]
masak Tene: yes I know
I'm just not sure that applies in perl 6
Tene pugs: my @a = 1, 2; my @b = @a; print @b.perl;
exp_evalbot OUTPUT[[1, 2]]
Tene pugs: my @a = 1, 2; my @b = [@a]; print @b.perl;
exp_evalbot OUTPUT[[[1, 2],]]
Tene Should there be a difference between the second two?
pugs: my @a = 1, 2; my @b := [@a]; print @b.perl;
exp_evalbot OUTPUT[[[1, 2],]] 17:53
masak Tene: I don't know. my brain hurts thinking about it
Tene masak: I don't know if it's what we should want or if matches the spec, but it seems consistent to me. 17:54
masak @ask TimToady what `my @a = []` should put in @a, [] or [[]]? pugs now does the latter 17:55
lambdabot Consider it noted.
masak @thx
lambdabot you are welcome
pmurias masak: i think you rationale proves that @array = []; sets the first element to []
masak pmurias: go on 17:56
Tene masak: you can think of anything in list context as being wrapped in ( ... )
pmurias it wouldn't be possible to recognise what @bar = $foo does with knowing the type of $foo
which would be bad
masak agreed. 17:57
pmurias eval: my @a = (1,2,3);@b = @a;say @a; 18:00
Tene pugs: my @a = (1,2,3); @b = @a; say @b.perl; 18:01

pmurias good ;)
TimToady [] always produces a scalar value, even in list context 18:12
lambdabot TimToady: You have 1 new message. '/msg lambdabot @messages' to read it.
Tene That's what I thought.
masak ah, so pugs's output [[]] was correct, and y'all were right. I stand corrected. 18:25

wolverian ouch 19:12
pmurias sorry 19:29
how should be perl5 and perl6 modules be seperated at use time in kp6 (a different PERL6LIB env variable?) 19:37
and possibly failing back on PERL5LIB? 19:38
