vrurg What is the difference between the two signatures? Why does it work with $_ but fails with Whatever? 00:13

Zoffix vrurg: because whatever doesn't close over the `~~` 00:19
So the difference is the first one is like `{ *.all ~~ Str }` I think there's a ticket somewhere to detect and complain about that case 00:20
m: sub foo( *@v where .all ~~ Str ) { note "ok" }; foo( |<a b c> )
camelia ok
Zoffix There's also WhereList module
eco: WhereList
buggable Zoffix, WhereList 'Simpler `where` constraints for items of lists': modules.perl6.org/dist/WhereList:gi...fix%20Znet
Zoffix Ticket is R#2086 00:21
synopsebot R#2086 [open]: github.com/rakudo/rakudo/issues/2086 [LTA][RFC] Maybe warn when thunking `*.foo ~~ $bar` constructs?
vrurg Zoffix: Thanks!
I would agree with the ticket: a warning would be helpful here. .all is perfectly ok with me. Though sub foo( Str *@v ) { ... } would do even better! ;) 00:22
TimToady m: say *.all ~~ WhateverCode
camelia True
TimToady that also wants to work
and you can't have both
Zoffix But that's not a thunk, is it? 00:23
TimToady sure it is, but * isn't a parameter for it 00:24
well, depends on how you define thunk, I guess
I can see calling it not-a-thunk too
Zoffix I mean were's not creating a thunk whose body is `*.all ~~ WhateverCode` 00:25
TimToady right
00:25 kerframil left
TimToady there's no deferred execution from the ~~ 00:25
the deferred execution is due to the where, which does make it a thunk
00:25 noobst_ joined
TimToady just as && and || thunkify their right sides 00:26
Zoffix So we can add a warning to the thunk-making in `where` clauses to warn if we see we're trying to thunk a QAST for `*.foo ~~ bar`
00:26 p6bannerbot sets mode: +v noobst_
Zoffix m: 42 andthen *.all ~~ WhateverCode andthen .say 00:26
camelia True
Zoffix I guess not here tho,
oh wait, yeah here too 00:27
TimToady sometimes it's okay to warn about things that are almost certainly wrong but could conceivably be intended
when I do that, I'm always careful to mention a way to disable the warning 00:28
00:28 mcmillhj joined
TimToady but yeah, it's like the double closure warning 00:28
m: my $x = { *.abs == 42 } 00:29
camelia 5===SORRY!5=== Error while compiling <tmp>
Malformed double closure; WhateverCode is already a closure without curlies, so either remove the curlies or use valid parameter syntax instead of *
at <tmp>:1
------> 3my $x = { *.abs == 42 }7⏏…
Zoffix yeah
00:29 p6bannerbot sets mode: +v mcmillhj
TimToady so there's some prior art there 00:29
00:30 noobst_ left
Zoffix Success: I built 2018.06 on Win10 and it works fine for me. Garbage print on default prompt. Proper output after setting chcp 65001 mode. 00:30
TimToady in fact, I see that we make that one fatal
Zoffix Success: I actually seen that error recently when doing something with `.close` and the code did not have any concurrency in it, so perhaps there is some compiler bug lurking in there. You could file a bug report with details of your system/perl6 and how to reproduce the bug: github.com/rakudo/rakudo/issues/new 00:31
00:32 leont left 00:33 mcmillhj left 00:34 someplace16 joined
Zoffix Seen that bug here: github.com/rakudo/rakudo/issues/22...-420632312 so you could mention that comment in your ticket, if you gonna file 00:34
Zoffix &
00:34 Zoffix left, p6bannerbot sets mode: +v someplace16
vrurg While I'm digesting the info about thunking... What eventually breaks thunking in my example: .all or ~~? My guess is .all. 00:35
00:36 someplace16 left
vrurg m: sub foo( *@v where * ~~ Str ) { note "ok" }; foo( |<a b c> ) 00:37
camelia Constraint type check failed in binding to parameter '@v'; expected anonymous constraint to be met but got Array ($["a", "b", "c"])
in sub foo at <tmp> line 1
in block <unit> at <tmp> line 1
vrurg Ok, its clearly .all
TimToady * is not a thunk, so I don't know what you mean by "breaking" 00:38
00:39 dracosilv8 joined
TimToady also, Whatever is treated differently from WhateverCode 00:39
00:39 p6bannerbot sets mode: +v dracosilv8
TimToady m: say (* ~~ Str)("") 00:40
camelia True
TimToady m: say (*.self ~~ Str)("")
camelia No such method 'CALL-ME' for invocant of type 'Bool'

TimToady m: say (*.self ~~ WhateverCode)("") 00:41
camelia No such method 'CALL-ME' for invocant of type 'Bool'
in block <unit> at <tmp> line 1
TimToady m: say (*.self ~~ WhateverCode)
camelia True
TimToady m: say (* ~~ Whatever)
camelia { ... }
TimToady m: say (* ~~ Whatever)()
camelia Too few positionals passed; expected 1 argument but got 0
in block <unit> at <tmp> line 1
TimToady m: say (* ~~ Whatever)(*)
camelia True
00:42 dracosilv8 left
TimToady so * "works" directly on the left side of ~~, but not via WhateverCode 00:42
you only get one level as currently spec'ed 00:43
it's just one of those spots where a WAT is hidden behind several DWiMs 00:44
vrurg Another concept to fit into my brain... TimToady, thanks for explanation! Could you, please, point me at the spec? I definitely need to understand these things by knowelege, not intuition. 00:46
Or is it a precedence thing? 00:47

Zoffix vrurg: it's a hardcoded list of things: github.com/rakudo/rakudo/blob/da64...9634-L9665 there's a yet-to-be-fixed docs Issues on the topic D#2017 00:54
synopsebot D#2017 [open]: github.com/perl6/doc/issues/2017 [docs] Docs on Whatever curry could be clearer / don't cover everything
00:56 mcmillhj joined 00:57 p6bannerbot sets mode: +v mcmillhj
Zoffix `*` is "Whatever" in those comments, and an already-closurised thing is a "WhateverCode". So, for example in `*.uc.lc` => `*` Whatever => the `.uc` is a `callmethod` op, and so we make a WhateverCode => we now get to `.lc`, since `callmethod` op is level `3` in that list, we continue closing over it and make `{.uc.lc}`-equivalent closure (without the new scope). But `&infix:<~~>` is level 1, so with `*.all ~~ 00:58
Blah` => `.all` is callmethod op, we curry it => we get to `~~` op with WhateverCode in hands, and since `~~` is level 1, we don't curry anymore. But with `* ~~ Blah` we have a Whatever, not WhateverCode, on LHS, so we do curry the level 1 `~~` op

06:43 committable6 left
El_Che I don't use that in my signatures :) 06:43
TimToady but sure, that's fine if you want to name the invocant something other than 'self'
El_Che type and a default is good enough for me 06:44
TimToady it's just a normal parameter, which can have a type and a variable name
it's only the : at the end that magically makes it an invocant
06:44 committable6 joined 06:45 p6bannerbot sets mode: +v committable6
ToddAndmargo So the writer is using the `$input` name in `multi method words(Str:D $input: $limit = Inf --> Positional)` to make it more readable? If so, it worked 06:45

Zoffix .tell cognominal-p6 in the sub, you're defining an `only`, but in the op you're defining a `multi`. Native types don't get auto-unboxed in multi dispatch, so you either need to give it a native `str` as argument or change to take a Str arguemnt or define a second multi that takes a `Str` argument. m: multi infix:<~~~>(@t, str $s where $s.chars == 3 ) { say 3 }; ['a', 'b'] ~~~ my str $ = '(,)' 13:35

randc I have been looking into changing my comments to Pod documentation, but poking around other random modules it looks like the convention is to write all the Pod either before or after the code. Is there a way to do it inline... kind of like "javadoc comments" so I am not writing code comments & separate documentation comments? 15:03
15:10 galls joined 15:11 p6bannerbot sets mode: +v galls 15:14 galls left
geekosaur it's just convention. interleaving can have its own problems, mostly with respect to comprehension / breaking things up too much for readers 15:15
and usually the kind of comments you put inline like that want to be API documntation or code explanations, not necessarily end user /manual page 15:18
jmerelo randc: Yep, Perl6 has got several brief ways of doing that: docs.perl6.org/language/syntax#Mul...d_comments 15:19
randc: and it's better than javadoc, because you only need perl6 to produce the text. 15:20

camelia Default constructor for 'Foo' only takes named arguments

m: my @p = a => <a b c>; dd @p.Capture
camelia \(:a(("a", "b", "c")))
Zoffix ahg, no
vrurg TWEAK isn't good enough for me because I create objects using profiles in hashes. To many handwork then. 17:16

Demos[m] any guidence on when to use roles vs inheratance? 19:36
moritz Demos[m]: prefer roles whenever possible 19:37
timotimo Demos[m]: the perl6 denizens tend to suggest roles for code re-use and inheritance for liskov-y things
Zoffix Liskov-y being: en.wikipedia.org/wiki/Liskov_subst..._principle
[Coke] diakopter: not to my knowledge.
timotimo i.e. if one thing is supposed to always be valid when the other also is, inheritance can be better
Demos[m] hmm OK
19:38 andyrock15 joined, trqx24 joined, alexandre909921 joined
Demos[m] from reading the docs it seems the main difference is that roles have better checks for insanity 19:38

Native types don't get auto-unboxed in multi dispatch, so you either need to give it a native `str` as argument or change to take a Str arguemnt or define a second multi that takes a `Str` argument. m: multi infix:<~~~>(@t, str $s where $s.chars == 3 ) { say 3 }; ['a', 'b'] ~~~ my str $ = '(,)'

Demos[m] question on mixins: if I mix in a role that "does" another role that's already on the target object what's supposed to happen 20:20
in my code it seems a new role gets mixed in

jnthn Demos[m]: A runtime mixin effectively creates an anonymous subclass, composes the role in to that, and then changes the type of the object to that new anonymous type 20:29
Demos[m]: It's entirely possible to implement "the same" role at multiple levels of the inheritance tree
Demos[m] so I probably want any shared state to be a real base class (with is)? 20:30
jnthn Demos[m]: (Reason for "the same" is because roles are generic on the type they are composed in to, so actually what's composed is a concretization of the role)
Yes, if you have `role R { has $!state }; class C does R { }; class D is C does R { }` then you'd have a $!state in C and in D 20:31
