Zoffix .tell skids AFAIK our current policy is not to add multi candidates whose job is to merely print an error message that the user is used wrong arguments. For one, that muddies up introspection as it gives candidates that can't actually be used. The `unique`s issue could be addressed in other ways, though perhaps we should audit the entire codebase for this type of issue and address it uniformly throughout. 00:05

Zoffix Any idea what this offset calculation in whatever curry is about github.com/rakudo/rakudo/blob/mast...9652-L9655 ? At first, I thought it was to only curry `*+42` in constructs like `foo 1, 2, 3, *+42`, but when I dump QAST going through the curry, it's just the `*+42` portion. Which constructs would have offset other than 0?
Zoffix Ah, it's for metas 07:51
Zoffix With stuff like `5 R- *` we get Op<call>(Op<call>(META_OP), 5, *) and the offset makes it skip over Op<call>(META_OP) when raking for Whatevers 08:08
Don' 08:13
Don't get why it fails to parse if offset is always set to 0 tho :/
"Useless use of R- in sink context ... .Cannot resolve caller Numeric(Whatever: ); none of these signatures match:" for `5 R- *`
Oh, `$e` is set to $offset+$up_to arity. nevermind 08:14

These tests take just ≈0.7s to run but at the same time have a fairly high “success” rate (≈35% chance of failing on affected commits). Don't know if it's the best way to test a flapper like this, but I guess it's better than nothing.

Voldenet Is there any simple way to implement roles without building large-ish classes? 15:57
the actual question is: how to build cyclic iterable without much boilerplate involved
m: class CyclicIterable does Iterable {has $.i;submethod iterator {class :: does Iterator {has $.i;has $!c;method r { $!c = $!i.iterator };method o { $!c.pull-one };submethod TWEAK { self.r };method pull-one {my $v := self.o;if $v =:= IterationEnd {self.r;$v := self.o;};$v}}.new(:$!i);}};my $c = CyclicIterable.new(:i<232 234>).head(10).say;
camelia (232 234 232 234 232 234 232 234 232 234)
Voldenet this works

camelia (a b a b a b a b a b)

skids How far the comma-less adverb list syntax can be worked down into the syntax without introducing some sort of sticky ambiguity... I don't think has been thoroughly investigated? 20:21
moritz anyway, the error message is LTA 20:22
so we should consider it a bug either way
skids Yeah. 20:23
skids RT#124553 covers the NYI for params. Just that case though. 20:25

skids RT#125353 and RT#131089 also involve the NYIness. 20:29

xi- why is there no binary for rakudo-star 2018.01? 21:00
moritz because nobody made one, yet 21:02

Voldenet hm, this shows an error in a funny place
shouldn't it be shown before first .map?
moritz why? 21:20
the first .map looks fine
m: say <1 2 3> .map({ $_*2 })
camelia (2 4 6)
Voldenet m: <1 2 3>.map({ $_*2 }).&({ $^a }).say

Voldenet The last error actually makes sense
Voldenet The first error is a bit tough to understand, it's not the postfix call that's malformed, it actually can't be used there because of the space before .map 21:23
moritz on the other hand, if you leave out the & call, all is fine 21:30
and parsing typically commits to what it sees early on
Voldenet in fact, I wouldn't mind if .& operator meant 'call second operand with first operand' 21:40

tyil the perl stand at fosdem was awesome, much more people that showed interest in Perl 6 than I imagined 22:03
I'm planning to give two talks at fosdem next year on perl 6 myself :> 22:04
jnthn will try to make it next year :)
tyil there's also the dutch perl workshop in a couple months :3 22:05
jnthn Oh...details? 22:06
tyil perl.events/nlpwindex.html the site is still under development 22:07
but the information itself should be accurate
jnthn grumbles about the withdrawal of the Prague - Amsterdam sleeper train some years back 22:08
tyil never been to prague, I cant relate to your pain
jnthn It's just very convenient to go to the station in an evening and wake up roughly where you want to be in the morning :) 22:12
Whereas with day trains it's, like, a whole day 22:13
I'm tempted though...the dates are do-able even if not perfect.
colomon is there some obvious way I’m missing to get the list of directories in an IO::Path? Can obviously do a chain of .parent calls, but it feels like something common enough to be built in… 22:14
like /usr/local/bin goes to “use”, “local”, “bin" 22:15
*usr
timotimo colomon: you can grab its .spec and use things like split or splitdir or splitpath 22:17
no, splitpath is the volume/dirname/filename thing 22:18
jnthn tyil: Are you one of the organizers (or do you know who is)? 22:22
El_Che NLPW? theo 22:23
tyil jnthn: I am not one of the organisers, but I'll probably see them next tuesday at the perl monger meetup
jnthn El_Che: Ah, thanks :) 22:24
El_Che jnthn: 1 day workshop, 1 day perl6 course with Shitov
jnthn Yeah, I was thinking "hmm, I wonder if there'd be any interest in a Perl 6 training" and then noticed that yes, so much that somebody already is doing it. :-) 22:26
colomon timotimo++: splitdir, brill! wonder why it isn’t referenced by the IO::Path documentation, but it seems like exactly what I need
leont AFAIK it's still in a fairly early planning phase 22:27
El_Che jnthn: a cro training maybe?
or a more advanced parallel track?
jnthn Dunno, or a concurrency one
El_Che indeed
leont Oooh
jnthn I don't want to be a douche and compete with Andrew's one. :-) But if I can do something that'd attract a different audience instead, I'd consider it. 22:29
timotimo colomon: aye, a prominent link to the spec docs would be nice 22:34
Zoffix xi-: we're still testing release candidates. You can give RC0 a whirl; the binaries are at pl6anet.org/drop/ 22:42
xi- I just built it instead
would that be the same?
Zoffix nine: you probably saw, but `Actually use new-from-git-describe` is exploding travis again :) 22:42
xi-: I think so, yes.
Zoffix e: use QAST:from<NQP>; BEGIN try $*W.compile_time_evaluate: $, QAST::Want.new; say $!^.message 22:53

Zoffix That's the bug for the colonpair thing. Should be fairly easy to fix
gonna give it a go later tonight, unless someone beats me to it

shinobi-cl hello, perl6 23:42
gfldex m: say „Hello shinobi-cl!“
camelia Hello shinobi-cl!
gfldex .oO( Why is there no bot for that? ) 23:43
shinobi-cl I've finished a small module for perl6, a bidimensional array.... Before committing it to the perl6 modules repo, i would like some feedback. There is a small example on how to use it: github.com/shinobi/Data-StaticTable/wiki/How-To
gfldex shinobi-cl: I rarely see ‚get-‘ as a prefix for getters in Perl 6. And you seam not to like Whatever much. 23:51
gfldex m: say «We love {*}!» 23:52
camelia (We love * !)
shinobi-cl gfldex: Noted ✎. What do you suggest? i will remove them from the function names, they are not really required. And what do you mean by whatever? The * operator? How should i use it in this module? 23:54
gfldex m: my @a = [[1,2,3],<a b c>]; say @a[*;1]; 23:55
camelia (2 b) 23:55
gfldex m: subset StaticTable::Position of Int where * >= 1; sub s(StaticTable::Position $i){ dd $i }; s(*) 23:57
camelia Type check failed in binding to parameter '$i'; expected Int but got Whatever (*)
in sub s at <tmp> line 1
in block <unit> at <tmp> line 1
gfldex m: subset StaticTable::Position of Int where * >= 1|Whatever; sub s(StaticTable::Position $i){ dd $i }; s(*)
camelia Type check failed in binding to parameter '$i'; expected Int but got Whatever (*)
in sub s at <tmp> line 1
in block <unit> at <tmp> line 1
shinobi-cl gfldex: well.. there is a method to convert the statictable contents to a shaped array, so this should work. i will add it as a test though
AlexDaniel m: multi sub foo($ where /^x/) { nextwith ‘zzz’ }; multi sub foo($ where ‘yyy’) { say ‘yyy’ }; multi sub foo($ where ‘zzz’) { say ‘zzz’ }; foo(‘xx’) 23:58
camelia ( no output )
AlexDaniel why no output?
