ugexe hmm, i always thought only the first MAINline gets run 03:33
but that might be if you have two MAINs in different modules only one of them gets used 03:34
[Coke] ... there has beem a very annoying change on my osx 12.6 box; if I highlight text, ther is no highlight color until I stop the selection. then it highlights. any way to get this back to highlight-as-you-go greatly appreciated.

lizmat the "no" was on the question whether it should return a lazy list 10:12

grondilu I tried very naively to create a NativeCall to openssl's digest : gist.github.com/grondilu/e5d11be7b...119631c805 11:42
oh wait I thought it wasn't working but maybe it does 11:43
it was printing just "NativeCall::Types::CArray[uint8].new"
I thought that was just an empty array but when I coerce it to Str I get some numbers 11:44
oh yes it does work, I get the good hash. Pretty neat. 11:46

Nemokosch [[asd]] is the same as [asd] 13:56
I'm not sure what's the principle behind it since the square bracket is pretty much dedicated to these literals
mscha Too bad, no `.EVAL`-based solution for today's Advent of Code then... 13:57
Luckily, it's also valid JSON, and JSON _does_ do the right thing with [[8,7,6]].  :-) 14:03

Nemokosch so basically JS does 😛 14:09

mcmillhj What's the correct way to iterate through an array in pairs in Raku? I was trying `for @d -> ($l, $r) { dd [$l, $r]; }` but that isn't quite right 15:32
tellable6 2022-01-04T08:50:00Z #raku <SmokeMachine> .tell mcmillhj it seems you’ve just missed the sigil… (glot.io/snippets/g5scg1bf5l)
Nemokosch wow 🤣
mcmillhj: can you give an example of what @d would contain? 15:33
mcmillhj yep, sorry.
m: my @d = [[1], [2], [3], [4]]; for @d -> (@l, @r) { dd [@l, @r]; }
camelia Type check failed in binding to parameter '@l'; expected Positional but got Int (1)
in block <unit> at <tmp> line 1
mcmillhj shoot, sorry 1 sec
m: my @d = [[1], [2], [3], [4]]; for @d -> ($l, $r) { dd [$l, $r]; } 15:34
camelia Too few positionals passed to '<anon>'; expected 2 arguments but got 1 in sub-signature
in block <unit> at <tmp> line 1
dutchie m: my @d = [[1], [2], [3], [4]]; for @d -> $l, $r { dd [$l, $r]; } 15:36
camelia [[1], [2]]
[[3], [4]]
mcmillhj oh, what does wrapping `$l` and `$r` in `()` tell to the compiler. I must not quite understand that.
dutchie `-> ($l, $r) {}` takes one argument and deconstructs it
mcmillhj ahh, okay. thank you dutchie. 15:37
mscha m: my @d = [[1], [2], [3], [4]]; for @d.rotor(2) -> ($l, $r) { dd [$l, $r]; } # works as well

camelia WARNINGS for <tmp>:

mcmillhj m: my @L = [[]]; dd @L;
camelia Array @L = []
mcmillhj ^ how come `@L` gets collapsed here? The inner empty Array is removed.
Nemokosch very good question, just got mentioned like 2 hours ago 15:52
mcmillhj probably by someone else doing aoc :) I can check the logs
Nemokosch if I were to guess, [] doesn't say "put this inside an array" but "store this as an array" 15:53
I'm afraid this should be checked on the syntax level, unless you are lucky to pinpoint it somewhere in the docs
mscha "someone else doing aoc", yup, me.  :-) 15:54
Final version I'm happy with: github.com/mscha/aoc/blob/master/aoc2022/aoc13b
Nemokosch docs.raku.org/routine/[%20]
luck might be on our side today - this is just an operator 15:55
mcmillhj Oh okay, I initially did today's problem in JS because the input was valid JSON. Was trying to clean it up in Raku. I did a similar multi sub compare but wasn't zipping the two lists together. 15:56
Nemokosch 😂 15:58
mscha The input is also valid Perl with `eval`, but not Raku with `.EVAL`.  Well, it's valid Raku, but it collapses arrays with one element, that's why this came up before.
Nemokosch lately, I've been addicted to this module that helps you look up source code in the compiler 15:59
so here we go: github.com/rakudo/rakudo/blob/704a...rs.pm6#L13
the very line that gets triggered
Array.from-list([]) gives []
the source also hints that [$[]] would indeed be an array inside an array 16:02

Xliff Hi ho! 16:11
tellable6 2022-12-09T20:03:16Z #raku <guifa> Xliff: you can override it by wrapping it
Xliff Congrats on the release of RakuAST to main: nine++, vrurg++
However, can someone tell me why this isn't working?
RAKUDO_RAKUAST=1 raku call.t
vrurg Xliff: do you take into account that RakuAST is far from being complete yet? 16:12
Xliff Yes. 16:13
However the tests should be working, yes?
Is that the correct way to invoke a RAKUAST enabled program? 16:14
And that is t/12-rakuast/call.t -- I thought that one WAS working?
mcmillhj mscha what does the `?*` passed to `.first(?*)` mean in your solution? 16:22
mscha First one with a true value.
Values are Less, Same, More.  More == 0, so ?More = False
Nemokosch bool conversion?
16:22 Tirifto left
mscha `first(*)` probably works as well. 16:23
Nemokosch you mean, Same == 0
mscha Yes, sorry, Same == 0, so ?Same == False
mcmillhj oh okay, that means the same thing as `.first(* != Same)` right? 16:24
16:24 Tirifto joined
mscha Yes 16:26
That might indeed be the cleanest way to do that 16:27
