samcv i think i've written up my talk's description gist.github.com/samcv/31d52d246999...c2b2b3bf33 i think it looks good. anybody got input? 00:47
hmm says i should have 100 and max 300 works. looks like that's 72 00:50
00:50 kurahaupo left
lookatme samcv++ don't know much about Unicode 00:50
00:51 kurahaupo joined
samcv that's my personal goal for unicode in perl 6. that the developer should only need to know the basics. and the rest should be easy to access 00:51
00:53 bwisti joined
samcv i'm thinking 45 minutes? 20 minutes sounds like too little 00:56
01:03 AlexDaniel left
lookatme samcv, They said `Tutorials (up to 180 minutes)` 01:09
samcv idk. how long should it be. you tell me
:P
i'm not sure how long to make it
lookatme Have you read that paper 01:11
act.perlconference.org/tpc-2017-ams...apers.html
01:11 bwisti left
samcv yes.. 01:12
180 minutes seems a bit long though
but it says 'up to'
lookatme yeah, ~~ up
samcv so how long do you think I should make it?
lookatme maybe 45 minutes, as you said before, haha 01:13
a lesson about Unicode 01:14
Perl6 Unicode
But I think you should estimate time according your topic, like a lesson prepare 01:16

samcv hm what arguments would seem good for $*COLLATION.set(primary => 1/-1/0) or maybe primary => More/Less/Same 02:44
though idk how useful More/Less/Same seem?
i mean actually you could supply either. since More/Less/Same really are just 1/-1/0 02:45
lookatme The second one is readable 02:49
But the first one is easy to write ... 02:50
How about make that default argument ? 02:51

03:03 cpage_ joined
samcv lookatme, yeah the defaults are all 1 03:06
unless you set it otherwise
lookatme Oh. What's the mean of **primary** 03:12
samcv different letters 03:15
secondary is diacritic, tertiary is case
so you will be able to change the sorting of case without effecting the sorting by letter and diacritic for example
or move diacritics before the primary character in the sort instead of them come after 03:16
or you can turn any of the three levels off
fully customizable sort
well maybe not *fully* but as long as you want primary. secondary, tertiary or quaternary(breaking ties with codepoint) 03:17
you can choose any direction enable/disable you wish
lookatme oh, awesome 03:19

05:52 keylet left, domidumont left
samcv you want comb keylet 05:53
though they seem to have gone
parv, split('') will give you empty strings at the start and end of the string 05:54
parv fish-slaps self for forgetting "comb". again.
samcv, yup; found that out after looking closely at the output. 05:56
... just goes to show how unfamiliar i still am due to lack of regular non-practice 05:57
oh, wait! that should have been "... lack of regular practice". 06:01
samcv hah. i knew comb did it. and honestly never thought to use split. but makes sense it would "work" 06:04

any tips
about to submit mine now

parv nebuchadnezzar, thanks. 06:13
moritz samcv: maybe a sentence or two? 06:14
samcv: I've given talks at two YAPC::EU's, but I'm not a professional speaker by any account, so take my advice with a grain of salt
nebuchadnezzar Time to go to work :-/ see you

parv is not collecting return value of a sub or a method an error? or, perl 6 would not care either? 06:55
moritz parv: there's an easy way to find out :-)
06:55 cognominal joined
parv moritz, oy, give me a fish please 06:57
07:06 lowbro joined, lowbro left, lowbro joined
parv turns out calling a value returning sub in void context is just fine w/ rakudo. 07:11
07:15 Cabanossi left, espadrine joined 07:16 Cabanossi joined 07:18 cognominal left
parv is there anything for undefined value besides Nil? 07:19
geekosaur type objects 07:20
m: my Int $x; dd $x
camelia Int $x = Int
parv i meant some value/function that would be undefined. 07:21
... to be returned from a sub.
moritz parv: sorry, was away for a bit; the easiest is to just run a very small, isolated test 07:23
m: sub f() { return 'ignored' }; f(); say "I'm still fine."
camelia I'm still fine.
07:24 grondilu left
parv moritz, thanks; no worries. i had done just that. 07:25
geekosaur perl6 has types, there is no untyped undef like perl 5 has 07:29
parv if a class attribute or a simple variable can be defined as "has Int $.x" or my Int $x = 3", then why cannot use the same syntax to return a value from a sub "sub ... { return Int 3 } " (instead of "Int(3)")? 07:30
geekosaur because Int is a type object, the undefined Int value 07:31
it cannot simultaneously be a function callable without parentheses, if you leave off the parentheses you get the type object
parv that (bare Int being a type object) should explain "two terms in a row" message. thanks geekosaur. 07:33
lookatme_ m: sub f() { return Int: 3; }; say f().WHAT; # Why is a List ? 07:34
camelia (List)
lookatme_ m: sub f() { return Int: 3; }; say f().perl; 07:35
camelia (Int, 3)
parv lookatme_, why does "Int: 3" not produce an error while "Int 3" does? 07:37
moritz "Int 3" is two terms in a row, which is a syntax error
07:38 ufobat left, domidumont left 07:39 domidumont joined
geekosaur the colon there is, I think, intended to be an alternative method call (foo.method: parameters). but there is no method to be called so it can't be that. capture perhaps? 07:40
(then "flattened" to a list for some reason) 07:41
lookatme_ m: sub f() { return: Int, 3; }; say f().WHAT; # same
camelia (List)
lookatme_ m: sub f() { return: Int, 3; }; say f().perl; # same
camelia (Int, 3)
geekosaur those two are not doing what you think, and probably not the same thing as the first 07:43
'return:' is a label
m: sub f() { glorp: Int, 3; }; say f().perl; # same
camelia (Int, 3)
07:43 zakharyas joined, rindolf joined
lookatme_ geekosaur, yeah, maybe, I just wonder why first one return a List. 07:44
07:45 uberbaud left
parv could "Int: 3" be "Adverbial pairs (colon pairs)" (docs.perl6.org/language/syntax)? 07:45
geekosaur the colon starts a colon pair, and would be two-terms-in-a-row there 07:46
colon pair is :foo(3) or :3foo or :foo (the latter becoming :foo(True))
lookatme_ parv, no 07:47
07:47 mscha left
parv ok. is there a name for "Int:" syntax so that I could search for that? 07:48
lookatme_ Oh, it's a parameter separator like `,`, but marks the argument to its left as the invocant. 07:50
m: sub f() { Int.return(3) }; say f().perl;
camelia (Int, 3)
lookatme_ But ..
07:51 Voldenet joined, Voldenet left, Voldenet joined
lookatme_ Why I can call a return on Int .. 07:51
geekosaur that was what I was thinking of when I mentioned captures... because I thought that was the only place that was valid
and, also, that question
lookatme_ m: sub f() { 2.return }; say f().perl;
camelia 2
geekosaur and of course searching the source for 'return' is less than helpful :p
lookatme_ OH, return is not only a "sub"(?right), but also a method 07:52
geekosaur welp. looks like 'return' is indeed a method (in Mu)
lookatme_ yeah, that's make sense now 07:53
geekosaur ahah, and its parameter *is* a capture
which is why the invocant syntax works
method return(|) ... 07:54
lookatme_ oh 07:55
pmurias are the encoding we support documented somewhere? I'm looking up what utf8-c is, so that I can implement it for the js backend
geekosaur utf8-c8 doc just got added today

parv rants: perl6 doc should replace "undef" with "Nil" already 08:12

pmurias parv: you mean when you are searching for "undef" but mean Nil? 08:16
08:16 Cabanossi joined 08:17 |oLa| joined
parv pmurias, no. At least in one example, a comment mentioned "undef" but should there is no such value of function. That specific mention should either be changed to "undefined", "unknown", or "Nil". 08:17

samcv hmm. may have to go back to a more complex method of it 09:10
since from as i can see here. negating both tertiary and secondary can cause primary to be ignored. and make 1 sort after a 09:11
so will have to fix that
09:11 jervo joined
samcv as secondary is 33 for both a and 1. and primary is 7231 for 1 and a is 7240. so very close 09:12

perlpilot mscha: that's just a slice

mscha Yeah, but it gets ugly in more complicated cases.

mscha jnthn: .clone.splice doesn't make things less ugly (my @b = @a.clone; @b.splice(...); @b). Writing my own sub is of course an option, but that's why I was asking - I was hoping that wasn't necessary. 14:23

18:27 Matthew[m] joined
[Coke] :$help in a signature means a named argument called help. when used in MAIN, named args translate as --options 18:27
geekosaur user3, you were writing it as "match a literal string normal parameter", you want "match as an option and set a flag if it is present"
:$help is the syntax for the latter, it sets $help to True if --help was passed as an option
[Coke] if someone passed in --help there, it would be available in that sub as $help , with a value of True 18:28
... again, too slow. :|

[Coke] has an idea for doc stuff: Make all doc only contributions to a branch (esp. edits through the web api); then all tests have to pass (including xt/) before merging it to master. 19:17

camelia ("s", "t", "r", "i", "n", "g").Seq
eveo [Coke]: that sounds like a good way to stifle contributions, especially quick typo fixes. Who'll be testing the branches, considering travis times out half the time? Considering the stuff xt tests test isn't critical, IMO it'd make more sense to leave them alone and only work on them once in a while. In fact, I don't mind making it it part of the Rakudo release process to ensure the docs xt tests pass, if in 19:33
exchange I can edit with web UI without being flagged for each typo. So this way, the typos, the tabs, spaces, non-nbsp Perl 6 and whatever else will at most surive for a month in the doc repo, and there'll be no barriers to contributions

using Log::Any increased the time for the test cases, round about double the time nwo 19:47
eveo ufobat: "now" do you mean by adding the module or by upgrading rakudo? 19:48
timotimo ufobat: github.com/timo/p6profiler-tools - this can generate a pretty svg from your stuff
also, you can use telemeh to figure out which threads are holding locks for how long
ufobat now be using Log::Any, not changeing rakudo

timotimo though it won't give you a "friendly" name for the threads involved
ufobat telemeh? 19:49
timotimo yup, if you Configure.pl your moarvm with --telemeh you get that
you can set MVM_TELEMETRY_LOG to a file 19:50
eveo Well, I see it's using a Channel for stuff and channel uses a lock to protect stuff, so that's probably where you're ghetting your src/core/Lock times from

eveo [Coke]: I'll fix then all the xt tests as part of rakudo's release process. We might not have a whole load of contributions flying in, but still, it's pretty distracting to be called in to hunt for some typo, and *new contributors* who don't know much about our setup might be put off from contributing at all if the process is difficult (and keep in mind, contributors to docs might feel encouraged to contribute 22:53
to other repos). The problem with the setup is there's no clear protocol for what to do *when stuff breaks*. Who fixes it? A contributor who might not appear for months? The setup jnthn++'s pre-Christmas proposal deliniates suffers from the same problem. As a commit might depend on nqp/MoarVM bumps + it's a bit tough to pin it to roast's state. I think the current system is sufficiently reliable: if a dev
feels their commit might break something they do it in a branch.

ugexe channel doesn't have a way to react to close/quit
.tap: { $channel.send($_) }, quit => { ... }; 23:02
er, Proc::Async uses a supply afaik. but Proc uses the method above with a channel^ 23:03
jnthn The Channel serves as a buffer
Since the reads are done synchronous, but Proc::Async is spewing stuff out as it arrives 23:04
So we shove it in the channel, and then synchronous reads just read off the channel, which nicely handles the blocking too.
ugexe why isn't .act used instead of .tap? 23:05
jnthn Sleep time; 'night o/
ugexe: Because they're the same almost always

jnthn (You *can* make a Supply that doesn't enforce delivering values one at a time, but you have to work pretty hard to make that happen.) 23:06
23:06 |oLa| left
jnthn The only built-in way to achieve it is making a Supplier and calling something like .unsanitized-Supply 23:07
Everything else is a serial Supply
ugexe ah, i was thinking it would help with, say, .act: { $str ~= $_ }
jnthn No, for Proc::Async it doesn't matter if you use .tap or .act 23:08

jnthn looks at the thermometer, sighs, and figures he'll give sleep a go anyway... 23:10
