andreoss m: subset Book where *.^lookup: 'isbn'; 08:56
camelia ( no output )
andreoss is there a better way to write that? especially if I want to check of method's signature? 08:57
timotimo i believe you can use can or cando for this purpose, though that is probably on a routine rather than a class 08:59
andreoss is it possible to place an anonymous trait somewhere? i.e `where * ~~ role { ... }`? 09:14
timotimo that will not do what you expect :) 09:16
it will match against this exact role, not by shape, but by identity
andreoss thanks. btw, why it's impossible to augment subsets? `subset Book ... { ...more methods here... }` 09:24
timotimo not possible i'm afraid
subsets are really just a matcher on top of an existing class 09:25
all the methods and attributes and such come only from the existing class / type
the matcher only changes how type checks act
andreoss i see, ^add_method does not work either 09:33
but you can call ^add_method inside `where` block, hmm 09:37
timotimo that operates on the whole type of whatever you're passing in 10:01
so if it's the exact class you're subtyping that will get the method, if it's a subclass, that will get the method
cpan-raku New module released to CPAN! Log::Colored (0.1.2) by 03TYIL 10:39
tyil been a while since cpan-raku highlighted me :'D 10:41
lizmat :-) 10:43
tyil jjatria: while I'm here, your RSS feed doesn't include a protocol in the links, which makes it not open the post on my rss reader (nextcloud) 10:44
and lastly
jmerelo: is it intended for the rakudo-star docker image to no longer come with zef? 10:45
(gitlab.com/tyil/perl6-app-assixt/-...3116#L301, zef not found error, goes away when I use a personal image where I'm sure zef is available) 10:46
JJAtria[m] tyil: Ha! Thanks. Well spotted 11:40
I might have to spend some time looking at whatever Jekyll plugin I used for that, but I'm leaning heavily towards moving away from Jekyll entirely at some point, so maybe that is the catalyst? 11:41
tyil my blog is using jekyll too, you can look at that for inspiration if you want to keep using jekyll 11:43
JJAtria[m] tyil: Thanks, I'll take a look. It's definitely going to be faster than "port whole site to different static generator" 11:50

tib Hello, what are the key features of the Rakudo compiler except being able to compile Raku and precompilation ? I can't find any list (rakudo.org/docs points to the manual page github.com/rakudo/rakudo/blob/master/README.md that does not have this infos). I found this web.archive.org/web/20150801100611/...s/features but it is mainly "Rakudo is able to compile full Raku" (which is already great). Maybe the answer i 14:08
dakkar your message got truncated at "maybe the answer" (IRC doesn't like long messages) 14:11
[Coke] your send cut of at "answer i"
dakkar++
dakkar (also I don't understand the question)
[Coke] Can you give an example of the kind of feature you mean? 14:13
(e.g. from another compiler?)
tib a page like this : www.moarvm.org/features.html but for rakudo
The end of my message was : Maybe the answer is "there is not" 😃 just asking 14:14
dakkar I mean, a compiler… compiles
that's the only thing it does
tib ok, any optims ?
[Coke] Rakudo is implementing the Raku language... so yes, the language features is what you want. 14:15
tib ok, thank you a lot 14:16
[Coke] there's really no other compiler to compare it to at this point if you're looking for "why use rakudo instead of <other compiler>"
guifa timotimo: alright thanks. Trying to improve load times on CLDR — was using given + when ‘longString’ and have cut it down to given + when int. In most cases, it’s under 12 items, so I can probably self-optimize with if/thens, unless arrays of code blocks would be even faster 16:29
MasterDuke m: my $a; $a = do given $_ { when 3 { "three" }; when 5 { "five" }; default { "default" } } for ^1_000_000; say now - INIT now; say $a 16:49

MasterDuke m:
m: my $a; $a = do given $_ { if $_ == 3 { "three" } elsif $_ == 5 { "five" } else { "default" } } for ^1_000_000; say now - INIT now; say $a
camelia 0.7213009
default
guifa MasterDuke: wow, that’s even more a speed reduction that I expected 16:51
guifa hasn’t started writing the new decoding code yet…. have to finish the encoding code 16:52
MasterDuke the `when`s compile to a chain of ACCEPT method calls, the `if`s to a chain of...drumroll please...`if`s 16:53
seems like some optimizations could be possible
guifa MasterDuke: I think the catch is that ~~ is not always the same as eq and ==, so I’m not sure if you can make that assumption 16:55
MasterDuke correct, but i bet something could be done in some cases 16:58
guifa let’s see how this one does 16:59
m: my @options = {“zero”}, {“one”}, {“two”}, {“three”}, {“four”}, {“five”}; my $time = now; my $a; $a = (@options[6.rand.floor] // {"default"})() for 1_000_000; say now - $time; say $a;

MitarashiDango[m Exercism has asked for programming language feature highlights. If anyone has input for Raku it would be appreciated: github.com/exercism/v3/issues/2763 23:23
timotimo hmm. malleable? reactive? (with react/supply/whenever) something with glue, like having Inline::Python and Inline::Perl5 23:42
