masak maybe an appropriate change to src/Perl6/Actions.pm:3109 would fix things. 09:41
then again, maybe not. :) in any case, it would be too big a yak shave just to get the June 30 blog post out.
the game will have to keep evolving for a while afterwards anyway. 09:42
huh. that's odd. 09:44
looking at the commit for that area of code, the !MAKE_REGEX routine in src/glue/regex.pir seems to be *specifically* made for handling arrays interpolated into regexes. 09:45
but I don't see it applying any infix:<|> semantics.

shinobicl hi... how do i handle a list of arrays as parameters? example : sub myfunc(@arr1, @arr2) and sub myfunc(@arr1, @arr2, @arr3) 17:51
moritz for now either you need to define separate multis for each arity, or pass the arrays as yourfanc([@arr1], [@arr2], ...) 17:52
though in nom you can already declare myfunc(**@LoL) { ... } 17:53
and that gets the nested list of all arrays passed to the sub, unflattened
nom: sub f(**@l) { say @l.perl }; my @a = 1, 2, 3; my @b = <a b c>; f @a; @b 17:54
p6eval nom: OUTPUT«LoL.new([1, 2, 3])␤»
moritz nom: sub f(**@l) { say @l.perl }; my @a = 1, 2, 3; my @b = <a b c>; f(@a; @b)
p6eval nom: OUTPUT«LoL.new((Array.new(1, 2, 3),), (Array.new("a", "b", "c"),))␤»
moritz nom: sub f(**@l) { say @l.perl }; my @a = 1, 2, 3; my @b = <a b c>; f(@a, @b)
p6eval nom: OUTPUT«LoL.new([1, 2, 3], ["a", "b", "c"])␤»
moritz ah, works with , too
shinobicl rakudo: sub myfunc(*@arrlist) { for (@arrlist) { say $_.WHAT }}; my @arr1=<1 2 3>; my @arr2 = <a b c d>; myfunc(@arr1); say '---'; myfunc(\@arr1, \@arr2); 17:56

masak moritz: yes, it works with infix:<,> because arrays do not flatten in captures.
shinobicl what is the meaning of ** ?
i know that * is 'flatten'
moritz shinobicl: * means "use up as many as you can"
shinobicl: and ** means "use up as many as you can, without flattening"
17:58 birdwindupbird joined
shinobicl ahhhhh, nice :) 17:59
sorear good * #perl6
shinobicl but maybe it should be the opposite way
* should be "use up as many as you can, without flattening"

shinobicl was there an operator for flattening an array? 18:25
flussence |@a
moritz .flat
flussence oh wait, .flat 18:26
different things
moritz both not wrong :-)
shinobicl i'm still thinking about * and **
flussence (is there a use for |@ outside function args?)
shinobicl * is "use as many as you can" and ** "use as many as you can without flatenning" 18:27
*@arr, **@arr, |@arr, i don't see a 'pattern' in here :S 18:28
masak I think *@arr is at the callee end, while |@arr is at the caller end. 18:29
moritz note that the first two happen at the callee side, and the last on the caller side
18:29 mj41 joined
masak at one point, the view was that they were the same on both ends. 18:29
for some reason, they're not.
moritz that's because they don't do the same thing 18:30
masak well, that's true for a lot of things on either side of a call with the *same* syntax.
so it can't be just that.
moritz for example?
masak :$arg creates a pair. 18:31
:$param denotes a named parameter.
moritz ":$arg creates a pair." is too simplistic
masak agreed.
but they don't do the same thing.
moritz it does marks it as named 18:32
so they don't do the same thing, but coressponding things
masak well, flattening and slurping are the same kind of corresponding things.
moritz so des | correspond to * or to ** ? 18:33
s/des/does/
masak I'd guess | corresponds to *, and || to **
but I haven't researched this deeply :)
sorear note that jnthn++ has talked about making *all* argument modification callee-side 18:34
moritz that doesn't really make sense to me in the context of multi dispatch 18:37
because the multi dispatcher has to act as if it works on a capture in which |@things are already interpolated 18:38
mathw apparently I'm no longer capable of building a usable Rakudo

when I did the hack for the modules to look in blib/ I didn't really consider installed nom 19:14

mathw I would politely suggest that it might be wise t ofix it before releases start off nom :) 19:15
moritz before nom becomes master, really 19:16
mathw that seems sensible
shinobicl i'm trying to implement this example i saw here in this irc channel: 19:17

shinobicl i don't undesrtand the syntax error :S
the original example was on rakudo, but only nom supports "**" for the moment 19:18
moritz die "Out of range" @values Z<= @onerange; # that's two terms in a row 19:20
though the error message sucks, yes
shinobicl nom: role Counter[**@ranges] { has @.ranges; method new(*@values) { for (@ranges) -> @onerange { die "Wrong number of args" unless onerange == @values; die "Out of range" unless @values Z<= @onerange; } self.bless(*, :@values); } }; 19:21

that might even be the cause of the error, if STD.pm6 assumes it's a listop and switches to term expectry.

mathw yes
unless the composer/engraver is a total arse
I suppose actually rather than imprecise it's more... incomplete 20:23
but really when you get down to it, somebody can write whatever they like on music in order to instruct the player to do something 20:25
