araraloren Hi03:31
When I call more than once `tap` on a Supply, what's the order when they be called ?03:34
Xliff m: my $supplier = Supplier.new; my $supply1 = $supplier.Supply; $supply1.tap(-> $v { say "1: $v" }); $supply1.tap(-> $v { say "2: $v" }); $supplier.emit(42);03:39
camelia rakudo-moar 762982046: OUTPUT: «1: 42␤2: 42␤»03:39
Xliff ^^ araraloren03:39
So, in order of the taps made on the supply.03:40
araraloren Xliff Can I write code reply on that order ?03:40
Xliff If you are doing this in a multithreaded manner, that order will be hard to define.03:40
araraloren oh, just in single thread03:40
Xliff araraloren: I don't really know. Based on that quick example, my guess is that the supplies execute based on a list.03:41
araraloren okay, Xliff03:41
thanks03:41
Xliff m: my $supplier = Supplier.new; my $supply1 = $supplier.Supply; $supply1.tap(-> $v { say "1: $v" }); $supply1.tap(-> $v { say "2: $v" }); $supply1.tap(-> $v { say "3: $v" }); $supplier.emit(42);03:41
camelia rakudo-moar 762982046: OUTPUT: «1: 42␤2: 42␤3: 42␤»03:41
Xliff Now if you get another sypply from the supplier, they should execute at the same time.03:41
araraloren sametime ?03:42
Xliff m: my $supplier = Supplier.new; my $supply1 = $supplier.Supply; $supply1.tap(-> $v { say "1: $v" }); $supply1.tap(-> $v { say "2: $v" }); $supply1.tap(-> $v { say "3: $v" }); my $supply2 = $supplier.Supply; $supply2.tap(-> $v { say "S2: $v"}); $supplier.emit(42);03:42
camelia rakudo-moar 762982046: OUTPUT: «1: 42␤2: 42␤3: 42␤S2: 42␤»03:42
Xliff Oh wow! I am... nonplussed.03:42
araraloren I don't think so :)03:43
Xliff m: my $supplier = Supplier.new; my $supply1 = $supplier.Supply; $supply1.tap(-> $v { say "1: $v" }); $supply1.tap(-> $v { say "2: $v" }); $supply2.tap(-> $v { say "S2: $v"}); $supply1.tap(-> $v { say "3: $v" }); my $supply2 = $supplier.Supply; $supplier.emit(42);03:43
camelia rakudo-moar 762982046: OUTPUT: «=== SORRY!=== Error while compiling <tmp>␤Variable '$supply2' is not declared. Did you mean any of these?␤ $supply1␤ &SUPPLY␤ Supply␤␤at <tmp>:1␤------> ); $supply1.tap(-> $v { say "2: $v" }); ⏏ $supply2.tap(-> $v { …» 03:43
araraloren if they are in single thread, they should execute in order03:43
Xliff m: my $supplier = Supplier.new; my $supply1 = $supplier.Supply; $supply1.tap(-> $v { say "1: $v" }); $supply1.tap(-> $v { say "2: $v" }); my $supply2 = $supplier.Supply; $supply2.tap(-> $v { say "S2: $v"}); $supply1.tap(-> $v { say "3: $v" }); $supplier.emit(42);03:43
camelia rakudo-moar 762982046: OUTPUT: «1: 42␤2: 42␤S2: 42␤3: 42␤»03:43
Xliff Right. Fork and the order gets complex.03:43
araraloren hmm03:44
okay, thanks03:44
I want to learn the react in Perl 603:44
Xliff Me to.03:47

Zoffix benjikun: how did you install your perl6?05:13
yoleaux 13 Jul 2018 21:49Z <samcv> Zoffix: I replied to that. thanks for the heads up05:13
benjikun Zoffix: cloning the rakudo/rakudo repo directly and going from there05:13
I'm redoing it now, will see if it works with rakudostar instead05:14
Zoffix benjikun: what steps did you use to build?05:14
geekosaur you need to update, possibly; recently some extops were removed05:14
Zoffix sounds like you missed nqp rebuild or forgot to run perl6 Configure.pl05:14
*perl05:14
← jameslenz left05:14
benjikun Nah I ran `perl Configure.pl --backend=moar --gen-nqp --gen-moar`05:14
Like normal05:15
geekosaur hm. bootstrap nqp might need to be regenerated?05:16
← mcmillhj left05:16
Zoffix never had any issues with this updater script: https://github.com/zoffixznet/r#linux05:17
benjikun btw Zoffix, the guy I'm working with on that financial API thingy had some moarvm level error earlier: https://pastebin.com/Y8p6XfJ005:18
Invalid pointer05:18
I believe it happened because he was using the windows subsystem for linux thing05:19
Zoffix benjikun: are you checking out a release tag or are you building HEAD?05:19
benjikun Zoffix: I built HEAD that time05:19
Zoffix benjikun: could be that's why. There's a bunch of issues on HEAD ATM, e.g. R#204705:20
synopsebot R#2047 [open] : https://github.com/rakudo/rakudo/issues/2047 [⚠ blocker ⚠] [WIP] Rescalar merge & other toaster-related stuff 05:20
benjikun Ah, I see05:20
Zoffix benjikun: you should build a release. The https://github.com/zoffixznet/r#linux script checks out a latest release on update05:20
benjikun Yeah, I'm just doing it from the latest rakudostar release now05:20
Zoffix huggable: star05:20
huggable Zoffix, Estimated Rakudo Star releases: .01, .04, .07 & .1005:20
benjikun We should put a warning not to use rakudobrew anymore on Zef's readme https://github.com/ugexe/zef05:21
Zoffix likely get a slightly more performant compiler if you build 2018.06 compiler release instead.05:21
Submit a PR :)05:21
benjikun why does rakudostar still come with LWP::Simple05:22
Zoffix What do you mean? Why shouldn't it?05:22
benjikun didn't we stop using LWP::Simple for some reason05:22
or stop recommending it05:22
Zoffix doesn't remember anything of the sort.05:23
benjikun hmm, maybe I'm just remembering nonsense lmao05:23

benjikun Zoffix: I just reinstalled everything using the 2018.06 release and I'm still getting the weird `failed to load library 'dynext/libperl6_ops_moar.so'`05:31
Zoffix benjikun: did you say this was on Windows?05:32
Can you check if you have any moar.exe processess running? It happens to me sometimes where an active process would silently interfer with rebuild05:33
benjikun Nah, this is on debian05:34
Zoffix benjikun: what's the full output of the reinstall session? Do you still have it?05:35

Zoffix benjikun: and the `load library` error comes only from zef? What about just `perl6 -e 'print 42'` ?05:40
benjikun Running `perl6` by itself gives the same thing05:40
Zoffix benjikun: what does `which perl6` give?05:41
benjikun UNLESS I'm in the directory in which it is installed05:41
oh what the heck05:41
geekosaur you have an old perl6 somewhere05:41
benjikun which perl6 gives `/home/perl6/.rakudo//perl6`05:41
lol05:41
not a typo05:41
Zoffix it should point to /home/perl6/.rakudo/install/bin/perl605:41
Then I think the error will go away05:41
benjikun I have the path set to include that too05:42
← mcmillhj left05:42
Zoffix My only paths for Perl 6 are $HOME/rakudo/install/bin:$HOME/rakudo/install/share/perl6/site/bin05:42
And I have rakduo installed in ~/rakudo05:43
geekosaur check for an alias?05:43
which could indeed include a doubled slash05:43
benjikun weird, I logged out and logged back in and it went away05:44
geekosaur hash -r05:44
...right. tracked alias.05:44

Woodi hi today :)09:18
can I precompile some simple script so it would run faster ?09:19
longer version: I have script that parses ~30 lines with grammar then sums and prints results. it takes 0.640s hot. but p5 version runs in 0.130s cold and 0.035s hot. --stagestats shows 0.400s is eaten by parse...09:22
is it script parsing or GRAMMAR.parse time ?09:23
64-bit debian so it is 19 x perl5. 32-bit is ~22x since few years...09:24
AlexDaniel I don't know if it's going to help noticeably, but you can move some stuff into a module09:26
Woodi but it's just 60 lines... arg parsing, printing :) but for benchmarking it's a good idea09:29
Ulti startup time of just the runtime is like 0.25s to 0.3s for me if you care that much might be easier to just make your program like a service so you arent paying that all the time09:32
→ woolfy joined09:35
Woodi moving grammar to module makes 0.580s09:38
Ulti: I mainly care for traditional *nix like usage :)09:38
← woolfy left09:38
AlexDaniel Woodi: so what else is taking time? Maybe there's a way to optimize your program?09:39
sure the startup time is a big chunk, but that still leaves ≈300ms of something09:39
Woodi that quite possible :) it's just naive use of grammar and for-each on the result. so possibly not good programming. but on the other hand pretty good, IMO, newcomer-like test case...09:41
lizmat Woodi: atm, putting the logic into a module is your best bet09:42
perhaps creating a module with a MAIN sub in it, and just running the module might work ?09:43
(a MAIN sub that doesn't get exported BTW)09:43
Woodi lizmat: that's a head scratch, a bit :) from total newcomer to v6 point of view. slicing small script and putting grammar and for loop into a module is WOOT at least :)09:47
but i realy wanted to learn all that MAIN programming, thanx :)09:48
lizmat for instance: module Foo { }09:49
my sub MAIN(|c) { dd c }09:49
evalable6 lizmat, rakudo-moar c567af736: OUTPUT: «\()␤»09:49
lizmat if you put that into a Foo.pm6 file09:49
Woodi checking...09:49
lizmat you can either run that as a script (it will run the sub MAIN)09:49
or you can just load it as a module with "use Foo" and MAIN won't get executed09:50

sarna I've been busy with trying to get a job14:10
I still don't have one, but the only thing I can do now is wait for potential employers to respond, so.. :)14:10
is it the first weekend of the month?14:10
timotimo squashable6: status14:11
squashable6 timotimo, Next SQUASHathon in 19 days and ≈19 hours (2018-08-04 UTC-12⌁UTC+14). See https://github.com/rakudo/rakudo/wiki/Monthly-Bug-Squash-Day14:11
sarna unbitrot?14:12
AlexDaniel also I'd appreciate help for organizing it14:12
sarna: the idea is that many modules in the ecosystem don't pass their tests14:12
so are essentially broken14:12
sarna of the whole ecosystem? hoo boy, gonna be fun14:12
← MasterDuke left14:13
← obfusk left14:13
AlexDaniel some of them are very old, some were “broken” by fixes in rakudo over time14:13
sarna AlexDaniel: I see14:13
AlexDaniel so we need a list of all failing modules, and then some way to distribute the work to for going through them14:13
honestly there's no plan yet, as I'm usually working on release-squashathon-release-squashathon clock14:14
releasable6: status14:14
releasable6 AlexDaniel, Next release in ≈7 days and ≈4 hours. 10 blockers. 0 out of 180 commits logged14:14
AlexDaniel, Details: https://gist.github.com/7415494f707bacc31008b8121268663714:15
AlexDaniel so I'd be looking at it in around two weeks14:15
if anybody else can organize it I'd be grateful14:15

sarna don't look at me, I wouldn't trust myself with important things14:17
AlexDaniel well, you can definitely do much better than me :)14:17
as long as you have time and interest of course14:18
sarna well, I could try14:19
but only if you promise I won't get extradited from #perl6 if I screw up14:19
AlexDaniel well, I'd be around anyway to assist :)14:21
with squashable6 bot and other things if needed14:21
although squashable6 is perhaps of no help in this case, as we can't track all of the modules in the ecosystem14:21
sarna alrighty then, what shall I do 👀14:22
timotimo why not? :P14:22
oh, we don't have control to put the hooks everywhere14:22
AlexDaniel yeah14:22
timotimo do we want a perl6communitymodulable btw?14:22
forks a module to the perl6 community account and changes ecosystem's meta.list to point to the new one?14:23
and back, once the original maintainer of a module returns14:23
just add it to the ~5000 open issues whateverable has :')14:23
sarna it only has 230 open issues :^)14:25
it's such a nice number though14:26

Kaypie what is the null multi_declarator in Perl6::Grammar meant to be used for? it's there, but it can't be used without slangs because term:sym<multi_declarator> only expects proto, multi, and only to be able to be used14:28
→ sarna_ joined14:29
moritz Kaypie: looks like dead code to me14:36
ah no14:36
timotimo is it what makes "multi foo" instead of "multi sub foo" work?14:36
AlexDaniel sarna_: so we need a list of things to do, and some way of tracking the progress… I don't know really, maybe we can/should modify squashable6?14:36
sarna_: for example maybe there should be a command like “gimme the list!!”14:37
sarna_: and it gives you a list of modules to look at14:37
sarna AlexDaniel: gimme the list of things to do or modules in the ecosystem?14:37
oh14:37
AlexDaniel yeah14:37
moritz Kaypie: it's probably for "sub foo" instead of "multi sub foo"14:37
AlexDaniel well can be both :)14:37
moritz it says sym<null>, but doesn't actually match the string 'null'14:38
AlexDaniel and then we can have a command like for saying “item X is done, comment: … … … …”14:38
or module X is done14:38
and it'll write down who did it and their comment14:38
sarna sounds rad14:38
AlexDaniel we can also have “give 10 things” or something like that, and it'd try not to give same tasks twice14:39
moritz irc frontend for a kanban board? :-)14:39
AlexDaniel so that we don't have multiple contributors working on the same thing14:40
moritz: actually… yea? yeah…14:40
I mean, if that is available somewhere, we don't need a bot, I'd say14:40
can we do something like this on github?14:40
like prepopulate a “Project” with a list of modules, and then anyone can drag them around and stuff like that14:40
moritz https://help.github.com/articles/about-project-boards/14:41
there's also trello, not integrated with git/github14:41
AlexDaniel so we can maybe have TODO | PR submitted | Fixed14:42
or something like that?14:42

El_Che we're talking about kanban14:42
so most of it is just out-my-ass talk14:43
(what I see at work)14:43
sarna and I have a question!14:43
I'll ask it before I forget14:43
m: loop (my UInt $i = 2; $i >= 0; $i--) {say $i;}14:43
camelia rakudo-moar 5cf0afce0: OUTPUT: «2␤Type check failed in assignment to $i; expected UInt but got Int (-1)␤ in block <unit> at <tmp> line 1␤␤1␤0␤»14:43
sarna oh! why didn't it run? on my machine it throws an error on runtime14:43
timotimo that is a runtime error :)14:44
sarna well, there was an output14:44
yeah14:44
I skimmed over it14:44
timotimo stderr and stdout get kind of jumbled up14:44
sarna can I somehow check it at compile time?14:44
AlexDaniel moritz: it's very on point, and we are brainstorming :)14:44
sarna I mean something like "hey your loop is while(true) and you probably don't want that"14:45
moritz AlexDaniel: :-)14:45
timotimo very difficult, as $i could be modified inside the loop body14:45
El_Che that would be a terrible loop :)14:46
sarna I wondered if we could check that because clang gave me a warning when I tried to do that on accident14:47
I'll try to modify i from inside the body and see what happens14:47
timotimo C is a lot more rigid :)14:47

← Aukai left14:49
→ Aukai joined14:49
sarna oh!14:50
well, look at the type, I mean14:50
i is UInt, and can't ever be < 014:50
timotimo problem is, we define UInt as a subset of Int "where * >= 0", which is code14:51
if we don't have a way to tell rakudo that this corresponds to a range, it won't be able to know14:51
sarna oh :(14:51
timotimo in your code i'd use Int instead of UInt; you're not going to reassign $i inside the block, are you? :P14:52
also, i'd probably use a ... operator and for loop, though if your code is performance-critical, the loop you have wins against that14:52
sarna it's just a toy example to illustrate what I meant :D14:53
timotimo right14:53
← Aukai left14:54
sarna still, that runtime exception is much better than getting UBd into oblivion14:55

timotimo p6noob: naked single quotes still have limited backslashing in them i think?16:18

uzl MasterDuke: Oh, I missed that. Will take care of it.16:19
According to the doc, Q() is interpreted as a function call. How is Q'' interpreted? And why does Q"" work?16:21
timotimo Q"" works because what comes after Q is interpreted as a quote16:21

→ Xliff joined16:29
Xliff \o16:29
timotimo yup, and perl6 grammar has only one place where it backtracks, and that's inside string interpolation16:29
so when it commits to interpreting it as an identifier, it sticks to that16:29
Xliff Is there an easy way to force an enum into its proper NativeCall type?16:29
Oh, and https://gist.github.com/Xliff/6b16cccd09cee13d543bed874573004216:30

Xliff OK. I will wait until I get to a stopping point and (try) to look into NativeCall.17:21
OK. Why not?17:21
timotimo are there ABIs that say not to clear the higher bits when passing a smaller int?17:22
Xliff Because it's not like we have a "is repr('CEnum')" yet.17:22
I am assuming that if that ABI asks for an enum that contains a 64 bit integer, it will take a 64 bit integer.17:22
timotimo yeah, but what if you don't care about some enum values and instead get a 32bit enum autodetected?17:23

Xliff Yes, but meanwhile I have code that I was hoping (foolish me) would just take the enum type and call it a day.17:24

TimToady well, in the case of "so" vs "Bool", that's just English vs Computerese :)18:54
and it also lets you shadow 'method so' without shadowing the basic conversion18:54
but for everyday programming, we tend to prefer things like given/when over things like switch/case18:56
so is more like the former, while Bool is more like the latter18:56
