[ptc] just wondering: is it possible to do an element-wise division (or multiplication for that matter) on an array? Something like Matlab's `./` operator? 12:49
I haven't been able to find anything in the docs, so I thought I'd ask here :-) 12:50
m: ($_ / 10 for 1..11) 12:54
camelia WARNINGS for <tmp>:
Useless use of "/" in expression "$_ / 10" in sink context (line 1)
[ptc] m: (1..11) >>/>> 10 12:57
camelia Potential difficulties:
Useless use of >>/>> in sink context

------> 3(1..11) 7⏏5>>/>> 10
[ptc] menno
m: say((1..11) >>/>> 10)
camelia (0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9 1 1.1)
[ptc] ok, that seemed to work. Is there a better/more elegant way to do the same thing? 12:59
i.e. could one do `(1..11)./10` ?
dakkar m: say (1..11).map:*/10 13:00
camelia 5===SORRY!5=== Error while compiling <tmp>
at <tmp>:1
------> 3say (1..11).map:7⏏5*/10

dakkar uh…
m: say (1..11).map: */10
camelia (0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9 1 1.1)
dakkar (one day I'll remember that whitespace is sometimes significant in Raku…) 13:01
guifa m: say 1..11 X/ 10
camelia (0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9 1 1.1)
dakkar oh, that's clever but I'd nix it in a code review 13:02
too risky having a list-that's-accidentally-1-long
guifa m: say (1,) X/ 10 13:03
camelia (0.1)
guifa it works okay with one element lists
dakkar [ptc]: how does Matlab's ./ operator behave when it's got arrays on both sides?
[ptc] dakkar: iirc it divides each element by the respective element in the other array. Hence it only works if the arrays are the same length. 13:04
dakkar guifa: sorry, I meant that `10` is a 1-element list, and someone is going to make it `(1..10) X/ (10,11)
[ptc] it's been a while since I've done matlab though
guifa: ooh, that's a nice solution! 13:05
guifa dakkar: ah. yeah, that would then give different results
dakkar for arrays of the same length:
m: say (1..10) Z/ (11..20)
camelia (0.090909 0.166667 0.230769 0.285714 0.333333 0.375 0.411765 0.444444 0.473684 0.5)
[ptc] dakkar: wow! Thanks! I was only intersted in the division by scalar case :-) I like the generalisation too! 13:07
dakkar explanation: X is the cross-product meta-op, Z is the "zip" meta op
say <a b> X~ <c d>
evalable6 (ac ad bc bd)
dakkar m:say <a b> Z~ <c d>

[ptc] cool, many thanks :-) 13:08
guifa if it’s something you’re going to be using a lot, and you want really fine control (throw an error if a list of nonmatching sizes are used, etc), you could also define your own operator 13:09
13:10 MasterDuke joined
guifa m: sub infix:<./> (@a, @b where @a == @b || die "Each side must have the same number of elements" ) { @a Z/ @b }; say (2,4,6) ./ (1,2,3); say (2,4,6) ./ (1,2) 13:10
camelia (2 2 2)
Each side must have the same number of elements
in sub infix:<./> at <tmp> line 1
in block <unit> at <tmp> line 1
guifa you could make it multi 13:11
so that you can handle Positional ./ Positional, and Positional ./ Numeric according to how matlab does 13:12
[ptc] yeah, I'd thought of that. Just wondered if there were something directly in the language and I'd just not spotted it in the docs

[Coke] I remember asking this years ago but cannot find the ticket: do we have a way for raku to tell us what version of unicode we support? 20:55
also, how long has there been tab completion in the REPL? nifty 20:56
m: 3.fmt("0.3d") # bet we could improve the error message here by asking if they forgot a % 20:58
camelia Your printf-style directives specify 0 arguments, but 1 argument was supplied
in block <unit> at <tmp> line 1
sena_kun [Coke], I think lizmat has worked on printf, so can ping and ask. 20:59
[Coke] (unicode) reminded by the thread on perl6-users
@lizmat: ^^ fmt question 21:00
MasterDuke i thought unicode version might be in -V output, but i don't see it
[Coke] Yah, might be nice to have it in -V output and also in a $* var. 21:04
El_Che I thought tab completion was handled by external libs and progs? 21:06
21:08 sena_kun left
[Coke] Sure, it's probably readline or linenoise, but I didn't realize it was there 21:10
21:13 seanrobert joined
guifa [Coke]: I actually believe most of the unicode stuff is in MoarVM rather than in Rakudo 21:31
[Coke] ... Sure, but I only ever run moarvm through rakudo. :) 21:33
guifa Fair :-) I only started using the JS backend recently 21:35
