tbrowder \o/ 12:00
tbrowder can anyone show how to dynamically create a Callable object? i would like to be able to create formatter callables to use with DateTime objects. 12:03
lizmat before RakuAST lands, EVAL is really the only option, if I understand you correctly 12:04
lizmat afk for a few hours& 12:06
tbrowder lizmat: thnx, i'll look into that 12:15
frost already read the weekly news, lizmat++ 13:05
tonyo tbrowder: do you have a syntax you're trying to get specifically? 14:01
you can do stuff like: 14:03
m: class A { method gist { "a!" } }; my $b = class :: is A { method gist { "b!" } }; A.new.say; $b.say
camelia a!
b!
tbrowder tonyo: i'll put it in a gist. are you gonna be around a few more minutes? 14:06
tonyo yea 14:10
day is just starting
[Coke] TIL about 'tmux capture-pane', nifty 14:28
tbrowder tonyo: the gist: gist.github.com/tbrowder/ac1857907...c27e9f15cc 14:35
tonyo tbrowder: that should already work with a few tweaks, you just want that in a class form? 14:36
actually, that should just work (thought self was referring to class instance)
tbrowder i have solved my immediate problem by generating the code with a raku program. it's a known set i need for now, but to be able to create them dynamically would be cool! 14:38
tonyo m: class A { method info { "A.info" }; }; my $f = sub ($s) { sprintf "got:%s", .info given $s }; say $f(A.new);
camelia got:A.info
tonyo tbrowder: ^ 14:39
El_Che will Vadim course be recorded? (aka no time now, but maybe interesting later)?
is it me or it's been a while since the last raku release? 14:41
tonyo if you want to do it with a class at runtime, given you'll know what formatter you want on object instantiation: 14:43
m: class A { has $.num = 0; has $!formatter; method formatter() { $!formatter() }; submethod TWEAK(|) { $!formatter = self.num < 10 ?? sub { "<10" } !! sub { ">=10" }; } }; A.new(:num(10)).formatter.say; A.new(:num(5)).formatter.say; 14:44
camelia >=10
<10
[Coke] El_Che: if I remember correctly, jdv had an issue running Blin that blocked the release. 14:45
El_Che I see
[Coke] I had tried a bit to get Blin setup, but I think the directions had some assumptions I missed. 14:46
tbrowder tonyo: very helpful, i'll give it a try, thank you soooo much!
[Coke] jdv: is there a ticket or gist somewhere with the issue you faced? 14:48
(ignore that, will move to the -dev channel
El_Che [Coke]: I find it interesting as well :) 14:59
tonyo tbrowder: any time 15:53
El_Che [Coke]: I expect a executive summary :) 15:56
[Coke] . 16:19
[Coke] sees an IRC disconnect that does NOT correspond to a local ISP issue. wow.
Nemokosch hahaha 16:20
[Coke] (I am up to over 200 ISP drops in the last 10 days or so; they finally seem to have stopped around midnight last night) 16:26
Rog What’s the default precedence level for user-defined infix ops? 16:54
Specifically relative to infix:<+> 16:55
Ah looks to be looser
[Coke] . 19:41
jdv boo 19:47
Nemokosch seems like -5 is not a <number> token, and eventually not a <value> token in the grammar of Raku 20:08
quite shocking news imo
I wanted to fix the "arrow return can't be a negative value" issue but I can't destroy half of the known universe on the way... 20:09
moritz channel your inner Thanos and do it! :-) 20:22
Nemokosch :DDD 20:24
guifa_ Nemokosch: that was designed to be part of raku's oddly consistent state. -1 is actually negating prefix + value 20:34
tellable6 guifa_, I'll pass your message to Nemokosch
Nemokosch I subconsciously misread it, as if that was a temporary phase, there is a reason why... 20:45
it's oddly inconsistent if you expect to be able to pass negative constants as function return values 20:47
there even is a "signed integer" token, it's just not a part of numish and consequenty number or value 20:49
[Coke] Blin is using v6.d.PREVIEW - that's out of date, yes? 21:05
ok, trying to run Blin with a checkout of Blin next to a checkout of whateverable with "raku -I../whateverable bin/blin.p6" ... I get the same Issue reported here: github.com/Raku/whateverable/issues/386 21:08
guifa_ Nemokosch: I think it should be eventually solvable. RakuAST in particular would make inserting a negative value there extremely easy 21:22
tellable6 guifa_, I'll pass your message to Nemokosch
gfldex By carefully stealing ideas from PWC submissions, today I learned that :nth takes a Range. This is very useful indeed! 21:56

Hmmm...

Xliff A raku Calendar in one line... :)
Wonder if anyone can make it shorter?
gfldex I'm not sure if a calendar with less then 12 months would help much. :-> 22:44
Xliff It's a single month, silly. :p 22:48
It can quickly be adapted to do the whole year with very little in the way of change. 22:49
But then it wouldn't be wise to leave it as a one liner.
gfldex m: $_ = now.Date.truncated-to('month'); $_ = $_ ..^ .later(:1months); put <Su Mo Tu We Th Fr Sa>; .put for (|(' ' xx (.[0].day-of-week)), |$_».day».fmt('%.2d')).rotor(7, :partial); 23:26

Well done. 23:27
I'm going to steal it.
gfldex Sharing is caring!
Xliff :)
gfldex It's wrong tho. .day-of-week starts at Monday. 23:31
Xliff Yup. It's why I use ^$sdow 23:32
