kawaii Hi, I'm a little confused about some code I have here. I send some data to a remote API and then use the same API to add some reactions (emojis) to the message - after this I then start a tap on the event supply for the message I created but it's picking up the two add-reaction() events from the first block of code. www.irccloud.com/pastebin/R3ukTWoV/ 11:03
am I misunderstanding something about how `start react` works?
my initial thought was that the event supply was sending historical events, but this isn't the case 11:04
surely since I am `awaiting` that first block of code, there's no way the latter half is running at all, is there? at least not until the first finishes
lizmat is not immediately seeing it, jnthn might 11:05
Altreus I feel better when the grown-ups also can't immediately see what's happening :D 11:06
jnthn kawaii: Certainly all the stuff in the `.then` block will have run before the `react` block is started (and you can probably confirm that by logging something before the `start react` line) 11:07
Altreus here's where the supply happens github.com/shuppet/p6-api-discord/...e.pm6#L150
I'm pretty sure I've used a live supply
jnthn Note that `start react` is "fire and forget", so if that were your full program it'd just exit (I'm guessing it's not) 11:08
Altreus it's not
I haven't hit him with the "post the whole code" learning stick enough yet
I think the tap on the line I just linked to might also be better as a start react whenever ... maybe? 11:10
vague memories of being told only to use a tap if I know I need to use a tap
jnthn Sorry, bit distracted debugging a pathalogical parser backtracking case at $dayjob... 11:18

chloekek Is there a way to get positional arguments into a hash without repeating their names? 19:17
In Perl 5 I could write: my %hash = ( foo => shift, bar => shift ); 19:18
I could do that in Raku but it’d be a variadic function: sub f(*@c) { my %hash = <foo bar> Z @c }. 19:19
19:21 sena_kun left
Altreus that sounds messy 19:22
You could make a multi function where the positional form calls the named form 19:23
19:24 kawaii left
AlexDaniel chloekek: you can still do that if you want 19:25
ah that's what you said in the last message :)
this almost works: 19:26
m: sub f(|c($foo, $bar)) { dd $foo; say c.pairs }; f 42, 50
camelia 42
(0 => 42 1 => 50)
chloekek p6: sub f($foo, $bar) { say MY:: }; f(1, 2) 19:31
camelia PseudoStash.new(($! => Nil, $*DISPATCHER => (Mu), $*NEXT-DISPATCHER => (Mu), $/ => Nil, $_ => (Any), $bar => 2, $foo => 1, $¢ => Nil))
Doc_Holliwood m: sub foo( $bar, $baz ) { my %h = :$bar, :$baz; }; dd foo('BAR', 'BAZ') 19:33
camelia Hash %h = {:bar("BAR"), :baz("BAZ")}
Doc_Holliwood chloekek: this? ^^
AlexDaniel “without repeating their names” :)
chloekek Still have to write the argument names twice, but that’s better than bar => $bar :) 19:34
tadzik well, you can probably still use @_ and shift like in Perl 5, for the most part :) 19:35
19:35 sena_kun joined
tadzik m: sub foo(*@args) { my %h = foo => @args.shift, bar => @args.shift; say %h.perl }; foo('bar', 'baz') 19:36
camelia {:bar("baz"), :foo("bar")}
AlexDaniel m: sub f($foo, $bar) { dd $_ for &?ROUTINE.signature.params }; f 42, 50
camelia Parameter $foo = $foo
Parameter $bar = $bar
tadzik oh that's just lovely AlexDaniel :D
AlexDaniel but then what? Look it up by name in MY:: ?
tadzik it's a good lead
you can eval them :>
Grinnz MY::? /me has ExtUtils::MakeMaker flashbacks 19:37
tadzik OH::MY
hrm, I seem to recall a time when you could declare a sub with no signature and it'd work Perl5 style... do I misremember? 19:39
now it doesn't compile as it assumes the signature is ()
AlexDaniel m: sub f($foo, $bar) { say $_, ‘ – ’, ::(.name) for &?ROUTINE.signature.params }; f 42, 50
camelia $foo – 42
$bar – 50
tadzik AlexDaniel++
AlexDaniel still not a hash though 19:40
but that's much easier to figure out
m: sub f($foo, $bar) { dd &?ROUTINE.signature.params.map({.name => ::(.name)}).hash }; f 42, 50 19:43
camelia Hash % = {("\$bar") => 50, ("\$foo") => 42}
AlexDaniel maybe there's a shorter way
btw I don't know why it puts () around keys

I know how to set up the grammar and actions, but I’m not sure how to set up the slangy part.
