I'll install the standalone comma for a while
the only problem I found was that I could install plugins I used on intellij

lizmat sena_kun: I guess it's about time to update Changelog Draft ? 11:17
MasterDuke huh, releasable6 counts closed tickets as blockers?
sena_kun lizmat, not yet, I think. I'm having breakfast now, then I'll look at blin output in revert branch. I think I'll also manually diff all files before PRs and after revert, because git can leave artifacts un-reverted. Also, someone has to confirm this fixes performance as I was too confused on how to run [Tux]++ CSV tests locally. 11:19
lizmat the revert has not been merged yet, right ?
sena_kun And given all of this works out nicely, I'll put up a changelog draft, the easiert piece.
lizmat, I really hope it isn't.

lizmat yeah ok :-) 11:20
sena_kun oh, I see new feedback

tigerpaws Hi. I'm new to raku, but I've used perl5 for 20 years, so I understand a bit. Can anybody point me to where in the documentation it describes the 'function: arg' syntax? (it's the colon I don't understand yet) 13:02
El_Che tigerpaws: it's a fat comma 13:10
it replace () in this case
function(arg)
for shorter stuff easier on the eyes
push @array: $elem 13:11
corresponds with push(@array, $elem) you know and love :)
tigerpaws @El_Che so, it's an operator? a circumflex operator?
El_Che I never looked it like that, mm 13:12
eg in signatures
sub MAIN(:$param) { ... }
it just means param => $param
I always just saw it as a shortcut in my head 13:13
tigerpaws: docs.raku.org/type/Pair 13:14
I think it's just a pair and the parens are just optional
Pair
lizmat in the case of push @array: elem, the colon is the invocant marker
Altai-man_ tigerpaws, this is alternative syntax when you don't want to put too many parens around. It goes well if you have multiline calls, e.g. `Person.new: name, age, some-long-stuff, <newline> some-more-long-stuff;`
lizmat it will basically make the parameter the invocant of the function
Altai-man_ oops, multiline call 13:15
lizmat so "push @a: value" is the same as [email@hidden.address]
El_Che lizmat: interesting
tigerpaws I understand the use in signatures. I'm doing a presentation at a meetup and I want to be able to answer questions. So, for marking the invocant, it's the term before the : that's the invocant. 13:16
El_Che You could turn it arround by saying everything is an object and most functions can be a method 13:17
split("foo faa", ' ') 13:18
"foo".split(' ')
MasterDuke didn't scimon (sp?) do a presentation awhile ago about all the uses of ':' in raku (perl 6 at the time)?
tigerpaws ok. I think I understand. I will practice it a bit to be sure. to be clear, it's just the equivalent of function(invocant, arg). If there are two args, does it still work? 13:19
lizmat tigerpaws: yeah, note it has the same use if you want to e.g. use the direct invocant, rather than a decontainerized one in a method
method foo(\SELF: $arg1, $arg2)
the name SELF is just that, could be anything (except "self" :-) 13:20
tigerpaws @MasterDuke Is there any place where that presentation is available? youtube, slideshare? I'd love to see it.
@lizmat I've been puzzling over this since yesterday. I'm building a jupyter notebook for my presentation and copying/adapting bits of code from many places, but didn't understand them all. The colon was a particular sore point. 13:22
lizmat "everybody wants the colon" is one of TimToady's well known expressions :-) 13:23
El_Che tigerpaws: in case you have twitter you can ping him? 13:24
tigerpaws: or I can ping him if you want 13:25
MasterDuke tigerpaws: a quick googling isn't finding anything, but i may have some of the details wrong
tigerpaws @El_Che ping scimon? or TimToady?
AlexDaniel thelackthereof.org/Perl6_Colons
awwaiid++
also blogs.perl.org/users/zoffix_znet/20...scopy.html 13:26
MasterDuke AlexDaniel++ better memory
El_Che ah great
and to think we were accussing scimon :)
tigerpaws @AlexDaniel Thanks. I'll check that out. 13:27
AlexDaniel MasterDuke: thelackthereof.org is using Oddmuse (which I used to maintain), it's not that I have better memory, it's just that there is a special place for that website in particular :)
tigerpaws You guys are great. I never thought I'd get answers this quick. 13:28
13:28 brtastic left
AlexDaniel tigerpaws: I don't see any mentions of it in the documentation, but indirect invocant syntax appears once: docs.perl6.org/language/objects#in...ant_syntax 13:29
tigerpaws I have a second question also on the syntax: in '(* + 2)(2)' what is it that makes the (* + 2) a function? Just the * or the () afterwards.
jnthn The * being an argment to an operator 13:30
lizmat * + 2 is really the same as { $_ + 2 }
AlexDaniel well, not the same… 13:31
but similar, yeah
jnthn (There are a few operators that opt out of this.)
lizmat well, what's the difference other than one is a WhateverCode, and the other is a Block ?
AlexDaniel lizmat: the signature, for example 13:32
you can call {} without args
m: { say $_; say 42 }()
camelia (Any)
42
AlexDaniel m: (* + 2)()
camelia Too few positionals passed; expected 1 argument but got 0
in block <unit> at <tmp> line 1
tigerpaws So it's a block because of the whatevercode and the () afterward? The whatevercode is always looking for an argument, so it needs to be a function, right? 13:34
jnthn tigerpaws: No, the () after doesn't matter.
AlexDaniel tigerpaws: () just calls it, it doesn't matter
jnthn m: my $a = * + 2; say $a(40)
camelia 42
jnthn You can even store it away in a variable.
AlexDaniel m: my $a = { $_ + 2 }; say $a(40) # just like any other block though 13:35
camelia 42
tigerpaws ok, so the existence of the whatevercode makes it a block.
AlexDaniel well, it's not really a block 13:36
I should've been clearer :)
but it's Code, yeah
lizmat: btw
m: dd (* + 2) 13:37
camelia { ... }
AlexDaniel lizmat: that makes it look like a block?
lizmat m: dd ((* + 2))
camelia { ... }
lizmat hmmm
AlexDaniel 6c: dd (* + 2) 13:38
tigerpaws So the compiler identifies it as a block. (I'm running 6.d)

AlexDaniel, (2016-03-04) github.com/rakudo/rakudo/commit/36...77bcde2865
jnthn m: my $x = * + 2; dd $x.^mro
camelia (WhateverCode, Code, Any, Mu)
jnthn Yeah, even by the type system it's not a block
lizmat m: say (*+2).raku 13:40
camelia { ... }
lizmat m: say ({ $_ + 2 }).raku
camelia -> ;; $_? is raw = OUTER::<$_> { #`(Block|64153088) ... }
AlexDaniel R#3653 13:42
linkable6 R#3653 [open]: github.com/rakudo/rakudo/issues/3653 WhateverCode.raku shows up as { … } but WhateverCode is not a Block
tigerpaws So WhateverCode is it's own type.
lizmat tigerpaws
yes
13:42 brtastic joined
tigerpaws This discussion is very interesting. I thought that the * was the Whatevercode, but it's not. It's the entire expression containing one or more *s. That changes things completely for my understanding. 13:45

linkable6 (2016-03-04) github.com/rakudo/rakudo/commit/360232a54f Make Code.perl a bit more sensical
AlexDaniel lizmat: it specifically ignores “whatever: SHA” because that's what bots tend to say
lizmat ah, ok 13:47
well, anyways, about 4 years ago, I changed it from "Code.new" to { ... }'
AlexDaniel lizmat: and it's a bit hard for a bot to know if you're a bot or not :D
by you I mean, *you* :)
lizmat I've been accused of being a bot :-)
tigerpaws Wow, this has been enlightening. 13:48
AlexDaniel lizmat: but… that's what bisectable6 linked above…
lizmat m: dd WhateverCode.new
camelia Cannot make a WhateverCode object using .new
in block <unit> at <tmp> line 1
lizmat so, making it that, would violate the roundtripping idea 13:49
jnthn lizmat: Um.... {...} doesn't round-trip either? :)
AlexDaniel lizmat: it's not like { … } roundtrips better
lizmat m: dd { ... }
camelia -> ;; $_? is raw = OUTER::<$_> { #`(Block|67238824) ... }
jnthn .raku.EVAL roundtripping for data is one thing, but for code there's never been any promises it will 13:50
tigerpaws @jnthn btw, I had sent you an email, but I guess this is a better place to ask my question. I wanted to know whether raku numerical arrays could be sparse (i.e. with NaN entries), and what happened with operators in that case?
lizmat m: my @a; @a[2] = 42; dd @a.map: * + 2 13:51
camelia Use of uninitialized value of type Any in numeric context
in block <unit> at <tmp> line 1
Use of uninitialized value of type Any in numeric context
in block <unit> at <tmp> line 1
(2, 2, 44).Seq
AlexDaniel my @a = 4,8,15,16; @a[1]:delete; .say for @a
evalable6 4
(Any)
15
16
lizmat tigerpaws: ^^
tigerpaws Ok, so they can be sparse, but we have to manage the 'Any' values ourselves if operating on an array like that. Got it. 13:53
jnthn Yes, what lizmat said. :)
tigerpaws Excellent. Wow, I've just learned a lot. I'll get back to the presentation I'm preparing, much wiser. Thank you all and I'll be back soon, because I've only started learning raku, it's only been three weeks since I saw my first jnthn presentation. 13:56

melezhik Hi community! I queued to RakuDist test a bunch of Raku modules that require native dependencies - repo.westus.cloudapp.azure.com/sparky/queue 16:47
so let's see what the test shows

AlexDaniel c: dispatcher-revert say 42
committable6 AlexDaniel, ¦dispatcher-revert: «42␤»
melezhik AlexDaniel: what do you mean?
AlexDaniel melezhik: so whateverable now allows you to run stuff on non-master commits
melezhik branches? 16:53
AlexDaniel melezhik: which means that rakudist can also be used to test experimental changes in rakudo and stuff
melezhik yeah, cool
AlexDaniel melezhik: yes, branches :)
melezhik now I am about to change RakuDist API to queue builds to Sparky, that highly-likely handles the load problem 16:54
so that now builds are in queue and my Azure VM won't overloaded :-) 16:55
also nice API as a benefit
AlexDaniel: AFIK git commits is commit, so one can select any branch by selecting proper commits 16:56

so RakuDist happens to be useful to reveal some errors :-) 17:14
some modules fail due to missing native libraries - repo.westus.cloudapp.azure.com/spar.../debian/49 17:16
is not a big deal to add them

El_Che spining off a pkgbuilder app that can build other stuff besides rakudo-pkg 20:31
tigerpaws @lizmat Ok, that works. That makes it tricky to figure ouyt what the endpoint needs to be. But I guess we can put that in the callable. 20:32
lizmat you can put a "last" in the producer Callable to indicate the end of the sequence, and use * as the endpoint
m: dd 1,2,3, { last } ... * 20:33

tigerpaws I just tried last and my machine is going into the next galaxy; but I didn't use * as the endpoint.
El_Che m: say ($_ + 5) * 2 for 5 ... 100

tigerpaws I'm doing a demo of a generator. I guess this is not a good callable for a demo.
El_Che tigerpaws: look for something that's awful impractical to do it the classical way 20:35

tigerpaws @El_Che: true. I'll have to think about it. Still, now that I know I have to match the endpoit exactly, I'm already further ahead. 20:37
robertle jnthn: github.com/robertlemmen/raku-readwritelock but only if you are bored, I'd appreciate any comments but the main questions I had did magically clarify themselves during the implementation... 20:39
tigerpaws Thanks, guys. There's so much to learn. I appreciate your help. Have a good evening or whatever. 20:41
El_Che tigerpaws: keep us posted on the talk 20:42
it sounds interesting
tigerpaws I will. It's in a Jupyter notebook, so I will make it publicly available once I translate it (it's in french). It's called ''A Few Tidbits of Raku' 20:43

El_Che Des petits morceaux de Raku :) 20:45
tigerpaws It's along the same lines as johnathan's "Emergent Program' talk, meant to point out interesting parts of Raku, but to non perl people.
Nearly:" Quelques bouchées de perles - Raku un langage ultra-moderne" 20:46
El_Che tapas!
:)
tigerpaws I'll keep you up to date. 20:47

El_Che I am probably doing something very stupid, but can someone have a look at my simple MAIN()? gist.github.com/nxadm/b01e357d9239...22f9caa259 21:09
I am trying to use an array as a named parameter
:@env in MAIN, if I pass "--env=value" MAIN exit with an error, if I run it with "--env=value --env=value2" I get both elements 21:10
21:11 brtastic left
MasterDuke i think that might be a known problem? 21:13
limitation might be more accurate?
El_Che That's not an array if it has only 1 element?
MasterDuke yeah 21:14
El_Che (didn't know about it and it has been driving me mad :) )
Thx 21:15
MasterDuke i'm only about 90% sure on that though, so should probably get a second opinion
AlexDaniel: ^^^ ?

guifa There's no way to store an anonymous multi sub in a &foo var, right? I feel like I've asked it before and got an answer but wanted to do double check 23:38
timotimo subs are lexically scoped, and you can return or store something from one scope into an outer scope, which is perhaps a good enough compromise towards an anonymous sub 23:50
