araraloren Hi 03:31
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 1: 42
2: 42
Xliff ^^ araraloren
So, in order of the taps made on the supply. 03:40
araraloren Xliff Can I write code reply on that order ?
Xliff If you are doing this in a multithreaded manner, that order will be hard to define.
araraloren oh, just in single thread
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, Xliff
thanks
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);
camelia 1: 42
2: 42
3: 42
Xliff Now if you get another sypply from the supplier, they should execute at the same time.
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);

S2: 42
Xliff Oh wow! I am... nonplussed.
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);

at <tmp>:1
------> 3); $supply1.tap(-> $v { say "2: $v" }); 7⏏5$supply2.tap(-> $v { …
araraloren if they are in single thread, they should execute in order
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);

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 up
benjikun Zoffix: cloning the rakudo/rakudo repo directly and going from there
I'm redoing it now, will see if it works with rakudostar instead 05:14
Zoffix benjikun: what steps did you use to build?
geekosaur you need to update, possibly; recently some extops were removed
Zoffix sounds like you missed nqp rebuild or forgot to run perl6 Configure.pl
*perl
05:14 jameslenz left
benjikun Nah I ran `perl Configure.pl --backend=moar --gen-nqp --gen-moar` 05:14
Like normal 05:15
geekosaur hm. bootstrap nqp might need to be regenerated? 05:16
05:16 mcmillhj left
Zoffix never had any issues with this updater script: github.com/zoffixznet/r#linux 05:17
benjikun btw Zoffix, the guy I'm working with on that financial API thingy had some moarvm level error earlier: pastebin.com/Y8p6XfJ0 05:18
Invalid pointer
I believe it happened because he was using the windows subsystem for linux thing 05:19
Zoffix benjikun: are you checking out a release tag or are you building HEAD?
benjikun Zoffix: I built HEAD that time
Zoffix benjikun: could be that's why. There's a bunch of issues on HEAD ATM, e.g. R#2047 05:20
synopsebot R#2047 [open]: github.com/rakudo/rakudo/issues/2047 [⚠ blocker ⚠] [WIP] Rescalar merge & other toaster-related stuff
benjikun Ah, I see
Zoffix benjikun: you should build a release. The github.com/zoffixznet/r#linux script checks out a latest release on update
benjikun Yeah, I'm just doing it from the latest rakudostar release now
Zoffix huggable: star
huggable Zoffix, Estimated Rakudo Star releases: .01, .04, .07 & .10
benjikun We should put a warning not to use rakudobrew anymore on Zef's readme github.com/ugexe/zef 05:21
Zoffix likely get a slightly more performant compiler if you build 2018.06 compiler release instead.
Submit a PR :)
benjikun why does rakudostar still come with LWP::Simple 05:22
Zoffix What do you mean? Why shouldn't it?
benjikun didn't we stop using LWP::Simple for some reason
or stop recommending it
Zoffix doesn't remember anything of the sort. 05:23
benjikun hmm, maybe I'm just remembering nonsense lmao

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 rebuild 05:33

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 thing
Zoffix benjikun: what does `which perl6` give? 05:41
benjikun UNLESS I'm in the directory in which it is installed
oh what the heck
geekosaur you have an old perl6 somewhere
benjikun which perl6 gives `/home/perl6/.rakudo//perl6`
lol
not a typo
Zoffix it should point to /home/perl6/.rakudo/install/bin/perl6
Then I think the error will go away
benjikun I have the path set to include that too 05:42
05:42 mcmillhj left
Zoffix My only paths for Perl 6 are $HOME/rakudo/install/bin:$HOME/rakudo/install/share/perl6/site/bin 05:42
And I have rakduo installed in ~/rakudo 05:43
geekosaur check for an alias?
which could indeed include a doubled slash
benjikun weird, I logged out and logged back in and it went away 05:44
geekosaur hash -r
...right. tracked alias.
Zoffix benjikun: and the load library error gone too? 05:45
benjikun Zoffix: yep

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 module 09:26
Woodi but it's just 60 lines... arg parsing, printing :) but for benchmarking it's a good idea 09:29
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 time 09:32
09:35 woolfy joined
Woodi moving grammar to module makes 0.580s 09:38
Ulti: I mainly care for traditional *nix like usage :)
09:38 woolfy left
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 something
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 bet 09:42
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)
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 }
evalable6 \()
lizmat if you put that into a Foo.pm6 file
Woodi checking...
lizmat you can either run that as a script (it will run the sub MAIN)
or you can just load it as a module with "use Foo" and MAIN won't get executed 09:50

sarna I'm sorry I wasn't there for the squashaton :( 14:09
timotimo there'll be another :) 14:10
sarna I've been busy with trying to get a job
I still don't have one, but the only thing I can do now is wait for potential employers to respond, so.. :)
is it the first weekend of the month?
timotimo squashable6: status 14:11
squashable6 timotimo, Next SQUASHathon in 19 days and ≈19 hours (2018-08-04 UTC-12⌁UTC+14). See github.com/rakudo/rakudo/wiki/Mont...Squash-Day
sarna unbitrot? 14:12
AlexDaniel also I'd appreciate help for organizing it
sarna: the idea is that many modules in the ecosystem don't pass their tests
so are essentially broken
sarna of the whole ecosystem? hoo boy, gonna be fun
14:13 MasterDuke left, obfusk left
AlexDaniel some of them are very old, some were “broken” by fixes in rakudo over time 14:13
sarna AlexDaniel: I see
AlexDaniel so we need a list of all failing modules, and then some way to distribute the work to for going through them
honestly there's no plan yet, as I'm usually working on release-squashathon-release-squashathon clock 14:14
releasable6: status
releasable6 AlexDaniel, Next release in ≈7 days and ≈4 hours. 10 blockers. 0 out of 180 commits logged
AlexDaniel, Details: gist.github.com/7415494f707bacc310...1212686637 14:15
AlexDaniel so I'd be looking at it in around two weeks
if anybody else can organize it I'd be grateful
14:16 MasterDuke joined
sarna don't look at me, I wouldn't trust myself with important things 14:17
AlexDaniel well, you can definitely do much better than me :)
as long as you have time and interest of course 14:18
sarna well, I could try 14:19
but only if you promise I won't get extradited from #perl6 if I screw up
AlexDaniel well, I'd be around anyway to assist :) 14:21
with squashable6 bot and other things if needed
although squashable6 is perhaps of no help in this case, as we can't track all of the modules in the ecosystem
sarna alrighty then, what shall I do 👀 14:22
timotimo why not? :P
oh, we don't have control to put the hooks everywhere
AlexDaniel yeah
timotimo do we want a perl6communitymodulable btw?
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 returns
just add it to the ~5000 open issues whateverable has :')
sarna it only has 230 open issues :^) 14:25
it's such a nice number though 14:26

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 used 14:28
14:29 sarna_ joined
moritz Kaypie: looks like dead code to me 14:36
ah no
timotimo is it what makes "multi foo" instead of "multi sub foo" work?
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?
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 at
sarna AlexDaniel: gimme the list of things to do or modules in the ecosystem?
oh
AlexDaniel yeah
moritz Kaypie: it's probably for "sub foo" instead of "multi sub foo"
AlexDaniel well can be both :)
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: … … … …”
or module X is done
and it'll write down who did it and their comment
sarna sounds rad
AlexDaniel we can also have “give 10 things” or something like that, and it'd try not to give same tasks twice 14:39
moritz irc frontend for a kanban board? :-)
AlexDaniel so that we don't have multiple contributors working on the same thing 14:40
moritz: actually… yea? yeah…
I mean, if that is available somewhere, we don't need a bot, I'd say
can we do something like this on github?
like prepopulate a “Project” with a list of modules, and then anyone can drag them around and stuff like that
moritz help.github.com/articles/about-project-boards/ 14:41
there's also trello, not integrated with git/github
AlexDaniel so we can maybe have TODO | PR submitted | Fixed 14:42
or something like that?
moritz I haven't followed most of the conversation; sorry if my comments are off/useless
sarna those github project boards look the most promising imo
El_Che we're talking about kanban
so most of it is just out-my-ass talk 14:43
(what I see at work)
sarna and I have a question!
I'll ask it before I forget
m: loop (my UInt $i = 2; $i >= 0; $i--) {say $i;}
camelia 2
Type check failed in assignment to $i; expected UInt but got Int (-1)
in block <unit> at <tmp> line 1

1
0
sarna oh! why didn't it run? on my machine it throws an error on runtime
timotimo that is a runtime error :) 14:44
sarna well, there was an output
yeah
I skimmed over it
timotimo stderr and stdout get kind of jumbled up
sarna can I somehow check it at compile time?
AlexDaniel moritz: it's very on point, and we are brainstorming :)
sarna I mean something like "hey your loop is while(true) and you probably don't want that" 14:45
moritz AlexDaniel: :-)
timotimo very difficult, as $i could be modified inside the loop body
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 accident 14:47
I'll try to modify i from inside the body and see what happens
timotimo C is a lot more rigid :)
14:48 Aukai joined 14:49 Aukai left, Aukai joined
sarna oh! 14:50
well, look at the type, I mean
i is UInt, and can't ever be < 0
timotimo problem is, we define UInt as a subset of Int "where * >= 0", which is code 14:51
if we don't have a way to tell rakudo that this corresponds to a range, it won't be able to know
sarna oh :(
timotimo in your code i'd use Int instead of UInt; you're not going to reassign $i inside the block, are you? :P 14:52
also, i'd probably use a ... operator and for loop, though if your code is performance-critical, the loop you have wins against that
sarna it's just a toy example to illustrate what I meant :D 14:53
timotimo right
14:54 Aukai left
sarna still, that runtime exception is much better than getting UBd into oblivion 14:55
timotimo UB?
oh, undefined behaviour 14:56
sarna yep
nasal demons :)

timotimo p6noob: naked single quotes still have limited backslashing in them i think? 16:18
p6noob yeah, there are differences, depends what is being conveyed in that cheatsheet, just seemed a bit weird to me as a starting recommendation. 16:19

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 quote

er

camelia Int $x'y = 5
geekosaur primes are valid in names
timotimo yeah, but only inside names, just like dashes
geekosaur which makes Q'... look like a name instead of a quote 16:29
16:29 Xliff joined
Xliff \o 16:29
timotimo yup, and perl6 grammar has only one place where it backtracks, and that's inside string interpolation
so when it commits to interpreting it as an identifier, it sticks to that
Xliff Is there an easy way to force an enum into its proper NativeCall type?
Oh, and gist.github.com/Xliff/6b16cccd09ce...8745730042 16:30
timotimo well, you can leave the first three numbers out ...
m: our enum Test <hello 0 goodbye 1>; say hello.^mro 16:31
camelia ((Test) (Int) (Cool) (Any) (Mu))
timotimo you don't have to use => if you don't want to 16:32
Xliff Well, it's best to be explicit, sometimes.
^mro?
timotimo method resolution order 16:34
Xliff Ah! Thanks.
timotimo had to make sure if it's an int enum
Xliff m: our enum Test <hello 0 goodbye 1>; say hello.enums.gist.say
camelia Map.new((0 => 1, 1 => 3, goodbye => 2, hello => 0))
True

Xliff timotimo: What do you think about checking the max value of the enum and converting it to either uint32 or uint64 automatically? 17:00
That way enums can just be... enums. 17:01
17:01 gabiruh left
timotimo but the difference comes only from how your nativecall sub's signature is set up? 17:01

oh, you mean you want to put the enum type in the function signature?
17:20 AlexDaniel left
Xliff Yes. 17:20
17:21 telex joined
timotimo d'oh 17:21
yeah, that makes sense
Xliff :)
timotimo but i'm not sure if autodetecting is a good idea
Xliff OK. I will wait until I get to a stopping point and (try) to look into NativeCall.
OK. Why not?
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.
I am assuming that if that ABI asks for an enum that contains a 64 bit integer, it will take a 64 bit integer.
timotimo yeah, but what if you don't care about some enum values and instead get a 32bit enum autodetected? 17:23
m: our int32 enum Test <hello 0 goodbye 1>
camelia 5===SORRY!5=== Error while compiling <tmp>

Xliff Why would you not care about some enum values?
timotimo m: our enum Test is int32 <hello 0 goodbye 1>
camelia 5===SORRY!5=== Error while compiling <tmp>
int32 does not support inheritance, so Test cannot inherit from it
at <tmp>:1
timotimo hm.
Xliff Now THAT would be fine. 17:24
timotimo it's bound to happen some day
Xliff Yes, but meanwhile I have code that I was hoping (foolish me) would just take the enum type and call it a day.
timotimo seems like we can't have that 17:25
maybe special-case enums in nativecall and give EnumHOW some storage for a native int type
17:32 skids left
Xliff :( 17:33
OK. Well... I am doing it the "proper" way. 17:34
m: our enum Test is int32 <hello 0 goodbye 1>; my Test $t = 2; $t.gist.say
camelia 5===SORRY!5=== Error while compiling <tmp>
int32 does not support inheritance, so Test cannot inherit from it
at <tmp>:1
Xliff m: our enum Test <hello 0 goodbye 1>; my Test $t = 2; $t.gist.say
camelia Type check failed in assignment to $t; expected Test but got Int (2)
in block <unit> at <tmp> line 1
Xliff m: our enum Test <hello 0 goodbye 1>; my Test $t = Test(2); $t.gist.say 17:35
camelia goodbye
Xliff So yeah... that will be.... interesting.
timotimo hm, +| and +& on an enum type don't give you an instance of the enum back (or an error if it can't be done)
coercion types also won't do i'm afraid 17:36
17:41 gabiruh joined
Xliff OK. Moving on. I am getting this error: Calling g_signal_connect_object() will never work with declared signature (NativeCall::Types::Pointer $app, Str $name, NativeCall::Types::Pointer $handler, NativeCall::Types::Pointer $data, uint32 $connect_flags --> uint64) 17:49
fake_space_whale Does while assign $_ to the result conditional statement?
Xliff When trying to match against this signature: gulong g_signal_connect_object (gpointer instance, const gchar *detailed_signal, GCallback c_handler, gpointer gobject, GConnectFlags connect_flags); 17:50
No, it shouldn'
fake_space_whale: No. I don't think so.

sarna hey, do you think we should add perl6 to websites like devdocs.io / zealdocs.org ? 17:55
or ask for it to be added at least
those sites do have perl, that's Perl5 though
seems like we should have to create it ourselves and contribute it to Dash kapeli.com/docsets 18:00

sena_kun sarna, personally, I think we should, but it depends on people willing to contribute. 18:09
sarna sena_kun: I'll look into it tomorrow or so 18:10
sena_kun And not only willing, but actually having time and enough, hmm, "power" to do so. 18:11
sarna, that'd be awesome. Generally, any improvements in code, docs, user experience, promotion/advertising are welcome, I'd say. :) 18:12

masak lizmat: that's a deep question :)
lizmat: I confess to being generally bewildered when it comes to what Perl 6 convenience methods like that should do. like, what's *really* the difference between .Bool and .so? between .gist and .Str? between .list and .Array? 18:47
I don't know. if there is a general rule, I'm not aware of it :/

18:52 domidumont left
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 conversion
but for everyday programming, we tend to prefer things like given/when over things like switch/case 18:56
so is more like the former, while Bool is more like the latter
"I have a Boolean here" is a rather indirect way to ask whether it's true or not 18:57

is there a wasm backend in the works for perl6? 21:00
DrForr Also while people are around, LibraryCheck::library-check() seems to throw 'Cannot invoke this object (REPR: Null; VMNull)' while running inside a function called from 'is native(...)' - it's the reason I'm searching along explicit paths rather than just calling library-check(). 21:01
El_Che veesh: not that I know of
veesh why not? would it be too big?
DrForr No volunteers, I'd guess. 21:02

veesh i'm dying to use perl in the browser
MasterDuke veesh: pmurias is working on a JS backend for rakudo
DrForr perlito compiles p5 to JS, and there's a JS backend in the works. 21:03
MasterDuke and a graalvm/truffle backend also
El_Che MasterDuke: I thought it was node based
TimToady he was mentioning possilby targeting wasm after that, but at the moment he's playing with truffle
veesh the js is node based now
apparently moving to browser based as longint support is added to modern browsers
something like that
