Demos[m] What;s the difference between a parameter Mu ::Type and Mu:U $type? 04:43
04:57 lichtkind joined 05:02 sauvin joined
guifa2 Mu ::Type captures the type of the object, regardless of whether it's defined or not 05:33
Mu:U $type requires you to pass an undefined object
m: sub foo(Mu ::Type) { say Type}; foo 2; foo Int; 05:34
camelia (Int)
(Int)
guifa2 m: sub foo(Mu:U $type) { say $type }; foo Int; foo 2 05:35
camelia (Int)
Parameter '$type' of routine 'foo' must be a type object of type 'Mu', not an object instance of type 'Int'. Did you forget a 'multi'?
in sub foo at <tmp> line 1
in block <unit> at <tmp> line 1
guifa2 Mu is implied though, since it's the root class. You can just use foo(::Type) and foo(:U $type)
Also, since the ::Type is a type capture proper, you can then use it in the signature: 05:36
m: sub foo(::Type, Type:D $a) { say "$a is a defined ", Type }; foo 2, 4; foo 'a', 4 05:38
camelia 4 is a defined (Int)
Type check failed in binding to parameter '$a'; expected Str but got Int (4)
in sub foo at <tmp> line 1
in block <unit> at <tmp> line 1
guifa2 Demos[m]: ^^ hope that helps. Note that in both cases, you can s/Mu/Foo and require the type to be a subclass of Foo or to be of role Foo. And lastly, when you say foo(::T, T $a, T $b), it's really short hand for foo(::T $, T $a, T $b), which might help make the distinction of what's going on clearer 05:42

Demos[m] hmm I had trouble with method foo(SomeType ::Type --> Type:D) 05:49
05:49 colomon left
Demos[m] return typecheck always failed 05:49
does ::T $ just say that the variable has scalar context?
sorry .... there are a lot of symbols and lots of ways to arrange them 05:50

Skarsnik Hello. is there a place to write test for... the Test module? x) 10:07
lizmat in the rakudo repository I guess ? 10:11
I think there are some tests for the Test module there already
10:13 aborazmeh joined, aborazmeh left, aborazmeh joined 10:19 expon joined
Skarsnik hm t/01-sanity/99-test-basic.t look like this is the place x) 10:19
expon i wrote a silly little sequence to make a list of before/after padding, but it doesn't terminate: (0;n), -> [$b,$a] {($b+1;$a-1)} … (n;0) 10:27
it does seem to smartmatch though, so i'm not sure why it's not terminating
10:29 hungrydonkey left 10:39 Altai-man_ joined 10:42 sena_kun left
lizmat expon: could you make an issue with an example of the code that doesn't do what you want? 10:42
expon lizmat: i can do that later sure, but the code above should be a decent example for any n > 0, as i think it should terminate logically :p 10:43
the raku github issues i assume? been a while
lizmat yes, please 10:44
it will help tremendously if people can just copy/paste to see the (wrong) result and not have to reason about it up front
expon i understand 10:45

chloekek When people put "version": "*" in their META6.json, what does that mean? 10:50
How is it to be compared against other versions?
p6: say '*'.Version <=> '1.2.3'.Version 10:51
camelia Less
chloekek p6: say '*'.Version <=> '0'.Version 10:52
camelia Less
chloekek p6: say '*'.Version «cmp« ('*', '0', '1.2.3')».Version 10:53
camelia (Same Less Less)
chloekek So it seems to be less than all other versions.
* is asciibetically less than 0, so that’s convenient. 10:58

Success i forget but i thought i saw where you could add custom infixes; in this case it would be equally effective for a builtin 'or' or 'xor' sorry i didn't thoroughly read the dox recently 11:59

guifa2 Demos[m]: It does seem that a captured type can't be used for a type check, that feels buggy 17:44
chloekek [Coke]: I wonder how tricky it would be to use a PSGI server with Inline::Perl5. 17:45

chloekek It’s annoying when developing and changing stuff, having to wait ten seconds before I can test something. 18:04
El_Che for developing, ok
chloekek In production it’s also annoying due to downtime, but this can be fixed by keeping the old version running and switching port numbers in the reverse proxy configuration. 18:05
El_Che container that are only reachable once the health check passes 18:06
that's what we doe with java stuff

El_Che when developing I mostly run the applicable tests, this limits wainiting time (in general, not only raku) 18:09
