Xliff Does nqp do classes? 01:31
01:33 epony joined 01:35 aborazmeh left
tbrowder xliff: yes 01:51
Xliff tbrowder: I take it you'd have to invoke methods using an nqp op? 01:54
tbrowder look in repo perl6/nqp/examples/use-classes.nqp for an example
invoking class methods looks like p6 unless you're doing something weird in the signature. 01:58
of course the method has nqpisms, say($s) vs say $s 01:59
sorry, haven't visited nqp for a while. invocation only one way afaik, see the example. class.method(sig) 02:04

timotimo old 10:00
10:00 veesh left
timotimo the new DLLs will require the littlest bit of work; they have different filenames, so GTK::Simple and others will probably have to be slightly altered to fit them again 10:01
i'm all out of windows, though :) 10:03
Xliff LOL 10:06
I want to see if I can get p6-GtkPlus working on Windows.
But I'd really like fresh DLLs to test against, since I 10:07
*I'm always fairly up-to-date on Linux
timotimo there are fresh dlls now! \o/
gtk-dlls.p6c.org/renamed/ 10:08
10:08 natrys joined
timotimo the build folder has the dlls packaged up 10:08
you can use the gtk-simple appveyor file as a template for "build dlls on a windows machine and make them available for download on appveyor's website or via an API" 10:10
Xliff Hmmm....
timotimo also, maybe you can figure out how to disable test suites for the things vcpkg builds, that'd surely make it at least 2x faster 10:12

cpan-p6 New module released to CPAN! Archive::Libarchive (0.0.12) by 03FRITH 10:49
Xliff timotimo: Will look into it. 10:51
wamiks Hi, I couldn't find an answer to question. Does a grammar's parse tree hold sub copies of the string at each node or just pointers to locns in the orig string? The memory size could be substantially different on a large tree depending. 11:03
timotimo it's just pointers 11:04
11:04 veesh joined
wamiks Cool, as I had hoped. thx! 11:04
timotimo however, using substr on a string already generates a pointer with start and length values to another string
that's a "rope" datastructure, it also supports repetition amounts for each piece
so "hello" x 1000000000 will be a very small string in memory 11:05
until you try to regex-match against it, which will force it to become one blob of contiguous memory for performance reasons
wamiks hmm. thx. very good to know. that could definitely be something I would do. :) 11:07

nadim_ timotimo: you may be interested by a simple filter I added to DDT, it "flattens" the tree and outputs: path, key, binder, ... tab separated so on can run the usual filters (cut, tr, grep, ..) on the data structure 11:48

nadim_ jflat, read a json file, just to have something to render, flattens it via a 2 lines filter and then it's up to you to write a nicve bash filter 13:44
timotimo github.com/akavel/up - i am vaguely reminded of this tool's existence
nadim_ yes I know about it, there is one more I'll try to find a link, I tried to write a pipe debuger some times ago but then got lazy 13:46
13:46 skids left
timotimo i'm just randomly musing is there's an interesting use case to combine the approach of up with perl6 and having ddt in there somehow 13:46

nadim_ ddd is great, my own stuff is a pain 13:53
timotimo in theory ddd is super cool, but i haven't used it much at all yet sadly
OK, in that case there isn't some kind of hidden terribleness that i just haven't found yet :)

vrurg SmokeMachine: I would let it go as it is. Best case scenario – this wouldn't happen often but may help squash a couple of bugs. Worst case – an end use see it and gets scared off. In the latter case it should be up to the developer to catch any error and wrap it into something user-digestable. 14:45

AlexDaniel and then stuff like this: modules.perl6.org/search/?q=zeromq
two modules with the same name… come on 19:55
one of them doesn't run at all, btw, so it can be just thrown away IMO
ugexe i dont think it makes much sense to spend time on changing how the ecosystem works. instead create a new ecosystem with different policy
AlexDaniel mmm 19:56
lizmat this is what a recommendation manager is about
AlexDaniel lizmat: can you elaborate? 19:57
sena_kun AlexDaniel, the idea is great, though I think we want a more agile approach, banhammer presence somehow irritates people, even if it is a pretty healthy thing to have. More like a "Modules that are not polished enough are moved to some sort of purgatory, if its author fixes it, it is back, otherwise it is just there and e.g. hidden in search, but you still can find it somehow".
AlexDaniel ugexe: I'm all for creating some kind of policy, whether for a new ecosystem or the existing one. Who's going to do it, though? Personally I don't think I know enough. Can you do it? 19:58

ugexe AlexDaniel: ideal policy will vary by consumer. if you target the noob looking for modules on modules.perl6.org it may not please the people working in business 20:06
if/when i release an ecosystem it will most likely target the later
policy wise 20:07
cpan-p6 New module released to CPAN! App::MoarVM::ConfprogCompiler (0.0.1) by 03TIMOTIMO 20:08
timotimo it me 20:09
ugexe but i wouldnt promote a policy that limits a namespace to a single instance either way.
perhaps a consensus system that can determine what gets the short name when querying based on things like reverse dependencies, upvotes, or other metrics. 20:10
Geth_ ¦ problem-solving: AlexDaniel self-assigned The ecosystem is a mess github.com/perl6/problem-solving/issues/39
ugexe i'd also point out that maybe modules.perl6.org is simply due to be rewritten. People don't seem to have many problems using zef alongside these duplicated module short names 20:12
but zef was written to handle that from the start
sena_kun and there is github.com/perl6/modules.perl6.org/issues/121 20:13
hmmm, so cro-openapi-routes-from-definition dies on 2019.03, but is fixed on latest rakudo. :/ 20:14
AlexDaniel ugexe: fwiw I think other tools can benefit greatly if some of the useful bits of Zef had a nicer API 20:15
ugexe: I remember doing some crazy stuff in Blin just to get things barely working, and still I don't think it handles duplicated short names properly
I remember trying to use guts from Zef to achieve some stuff, but IIRC I was not very successful at that 20:16
maybe I just suck, you know, but if Zef handles things correctly then maybe we should strive to make it nicer so that things can depend on it easily 20:17
ugexe that is a problem with almost any API with a bunch of loosely coupled components. 20:19
and the API is actually good if one knows how to use it 20:21
(not that anyone has a decent way of knowing how to use it)
20:22 kst joined 20:25 skids left
ugexe but i've been doing work the last few years to move many of the useful components into core perl6 itself 20:26
the Distribution interface and .candidates/reccomendation manager being the two big ones
AlexDaniel ugexe++ # that I actually noticed! 20:27

neutron_stz if i execute configuration as following: "perl Configure.pl --gen-moar --gen-nqp --backends=moar --prefix ~/rakudo", could i be able to run it like #!~/rakudo/perl6 as interpreter 20:40

timotimo does linux expand ~ in hashbangs? 20:41
i'd be mildly surprised
neutron_stz im not sure 20:42
20:42 Sgeo_ left
neutron_stz but i think so 20:42
timotimo if your prefix is ~/rakudo, then perl6 will land in ~/rakudo/bin/ 20:43
20:44 kaare_ left, kaare__ joined
neutron_stz then will be #!~/rakudo/bin/perl6 ? 20:45
timotimo if ~ works, then yes, that probably works 20:46
why not #!/usr/bin/env perl6 instead? 20:47
sena_kun 6c: say '/pets' ~~ / ^ [ '/' <-[/]>+:[ '/' <-[/]>+: ]? | '/' <-[/]>+:[ '/' <-[/]>+: ]? | '/' <-[/]>+: '/' <-[/]>+: | '/' <-[/]>+: '/' <-[/]>+: | <!> ] $ /;
timotimo that's kind of a more standard way
and it'll work on other systems, too
committable6 sena_kun, ¦6c (37 commits): «｢/pets｣␤»
neutron_stz okay, thx ill try 20:48
what you mean, to make the perfix /usr/bin ?

indeed! Different compiler!
timotimo: you're right! :)
timotimo that's ridiculous
i didn't mean to be right about this 21:34
AlexDaniel anybody wants to bisect gcc? 21:36
I don't feel like doing that today…
21:39 molaf left
timotimo hahaha 21:40
we should first check to see if the time difference lives inside libtommath or moarvm 21:41
probably not in the jit, since that shouldn't be dependent on the compiler
though a difference in compiler could change when jitting happens exactly

AlexDaniel again, that's not noise or something
timotimo ok, ok, it's reasonably stable
without running any performance measurement programs against it i don't have a clue 22:10
AlexDaniel so it's exactly this commit: github.com/MoarVM/MoarVM/commit/30...6cffa1be9d
may be a compiler difference again… not sure if I want to check
timotimo haha
OK, i'll go to bed for realsies 22:11
good luck! 22:12
you could start by running it via "time" and see if the maxresidentk changes drastically
shouldn't, but who knows
