manchicken So, I'm thinking of doing a series on NativeCall tutorials. Has anybody ever done that? 01:11
01:12 kyan joined
manchicken I'm trying to teach myself this, and I figured a neat little documentation project would be the easiest way of doing so. 01:12
perlawhi1l Hi people 01:13
kyan Just a heads up about a problem on the Web site: the body text is written from Camelia's perspective, but in a narrow/zoomed-in display, Camelia is hidden (presumably by CSS media queries). 01:14
perlawhi1l Can I check if a variable is contrained by a subset (without specifying the subset by name)... 01:15
m: subset Foo of Int where * > 0; my Foo $f = 5; say $f.WHAT;
camelia (Int)
perlawhi1l is there anything i can ask `$f` that will tell me it is contrained by subset Foo ?
timotimo ah yes, it's got the class img-responsile (also, center-block, not sure what that is for, exactly)
perlawhi1l besides $f ~~ Foo
timotimo $f.isa(Foo) perhaps, perlawhi1l
perlawhi1l ok, so unless I know the name of the subset in advance, I can ask. 01:16
can't
timotimo that's not true :)
m: subset Foo of Str where / "hi" /; my $which-to-check = "Foo"; say "oh hi" ~~ ::($which-to-check) 01:17
camelia True
timotimo m: subset Foo of Str where / "hi" /; my $which-to-check = "Int"; say "oh hi" ~~ ::($which-to-check)
camelia False
TimToady m: subset Foo of Str where / "hi" /; my $which-to-check = "Foo"; say "oh hi" ~~ $which-to-check
camelia False
TimToady m: subset Foo of Str where / "hi" /; my $which-to-check = Foo; say "oh hi" ~~ $which-to-check
camelia True
timotimo kyan: oh, actually, there's a media query for #welcome-header which has display: none !important, that's what's making it go away 01:18
TimToady still works even if the name is a .WHAT
timotimo greetings TimToady
TimToady granted you need ::() if you're only given a string 01:19
perlawhi1l so given `subset Foo of Int; my Foo $f;`... without typing the letters 'Foo', is there anything I can ask $f that returns 'Foo'
01:20 jeromelanteri joined
timotimo m: subset Foo of Int where 0 < * < 9; my Foo $var = 4; say $var.VAR.of 01:20
camelia (Foo)
TimToady m: subset Foo of Int; my Foo $f; say 42 ~~ $f.VAR.of
camelia True
timotimo that gives you the type object you can directly typecheck against
perlawhi1l thanks! TimToady++ 01:21
MasterDuke manchicken: i don't know of any
timotimo or you can .^name and get it as a string, and later get it from your lexical scope (important) with the ::() thing
TimToady but if $f is visible, why don' tyou know the type :)
perlawhi1l I do :D I just wanted to know how I can introspect it
timotimo well, it could have been passed in an "is raw" argument for example
manchicken MasterDuke, well then, I'll go ahead and do that. 01:22
I will likely also submit some pull requests.
First: how to play with C structs.
01:22 Slayerk joined
Slayerk Hi all! 01:22
manchicken (all of this is me learning enough to implement librabbitmq-c)
timotimo manchicken: i believe perl6-intro.com has a short intro to nativecall, too
TimToady m: sub foo(::T \sumpthin) { say 42 ~~ T }; foo(42)
camelia True
Slayerk Does Perl 6 have something like the delay function in C?
manchicken I'm going to make a quick GitHub repo that has a bunch of different stuff. 01:23
01:23 pilne joined
manchicken Slayerk, is that a Windows function? 01:23
I don't think that's a POSIX routine.
TimToady doesn't know what delay() does
timotimo Slayerk: if you're looking to actually block a thread, you'd use "sleep" (takes its argument in seconds, but allows fractions, of course)
otherwise you can "await Promise.in($seconds)" and other tasks can be done on the thread if it's in a thread pool scheduler (and you have version 6.d.PREVIEW turned on) 01:24
Slayerk manchiken: Not sure, sorry :P
TimToady well, I guess the question is what *you* want to do :) 01:25
Slayerk Well, I'm trying to make terminal animation :P
timotimo oh, have you considered looking at Terminal::Print, Slayerk? 01:27
TimToady sleep will likely be adequate for that, and it's not difficult to switch to promises if you need to later
Slayerk TimToady: Thanks, will see how it goes and will report back the results :) timotimo: Thanks for you advice
It works guys! 01:30

TimToady Zoffix: the :node($/) is mostly used for current line number, but the match object is the only way to convey everything in the "current language" to subsequent compiler passes, since dynvars (the old way to do that) go out of scope too soon 01:54

timotimo kyan: if you fix the page for mobile, maybe you can come up with something clever for the tabs above the examples box, too
01:55 haxmeister joined
TimToady which is why all the pragmas, braids, etc. now can be found via match objct methods 01:55
Zoffix TimToady: still unsure when it should be used though. Here I saw it passed to the callmethod op and then to the Var qast a few lines down as well: github.com/rakudo/rakudo/blob/mast...8131-L8134 01:56
Are both needed? vOv
kyan I'll look at it after finals week :) 01:59
TimToady in general we want every QAST node to know its line number, minimally, cuz we don't know who's gonna throw an error based on what 02:00
and there's already a node pointer in the QAST, so might as well fill it
the redundancy is more perceived than real
Zoffix OK :)
TimToady otherwise you start getting error messages that don't know the line number, or pragma decisions that don't know the values of their pragma, etc. 02:01
and basically you're just gonna keep a heap of pointers into the original match structure, but that match structure itself is not duplicated 02:03
Zoffix Ah
AndChat|688961 Just out of curiosity, would Perl6 be faster if the procedural Paradigm was removed, if Perl6 was strictly OO?
TimToady um, OO is essentially procedural underneath anyway, you're just hiding the variables inside objects 02:04
AndChat|688961 Oh, okay.
timotimo well, and you get method resolution order stuff. depending on whether you put multiple dispatch (or just overloaded methods) in there as well ...
in procedural code, you'd probably always know what a given piece of code is calling?
in fact, if you use subs or private methods nowadays, we're already selecting the right candidate up front where possible 02:05
02:05 AndChat|688961 is now known as comborico
TimToady now, with purely functional programming (FP), you try to avoid side effects, so you treat the data as immutable, and that can occasionally have some benefits for the optimizer, and you could call that "removing procedural code", but it's sort of the opposite way of controlling state changes from OO 02:07
comborico Oh. 02:08
TimToady OO tries to hide state changes inside objects, while FP tries to hide state changes in the parameter bindings of the call stack 02:09
manchicken Well poop. 02:10
NativeCall is giving me `image not found` issues.
TimToady which one is more efficient really depends on the nature of the problem you're trying to solve
manchicken The library is there, the symbols exist... but it's not loading.
timotimo "image"?
ah, it could very well be it's missing the "blah.so" file, and doesn't look for "blah.so.1.2.3"
TimToady I think there's a faq about that 02:11
timotimo you often have to install the corresponding -dev package to get those symlinks
manchicken The file is there. OSX.
timotimo oh, dylibs, then
TimToady I think the faq even mentions OSX
manchicken What's weird, I'm able to see it elsewhere.

and certainly one can revise a pull request if parts of it are problematic 03:41

Voldenet is there any way to supress stderr in qqx-invoked commands?
12:19 zakharyas left
Voldenet I could just 2>/dev/null in the command itself, but it doesn't look too great 12:20
moritz you'd have to use run instead of qx 12:21
12:25 silug left
Voldenet > sub qx(*@cmd){ given Proc::Async.new: @cmd { .stderr.tap({$}); my @o; .stdout.tap({ @o.push($_) }); await .start; @o }}; 12:33
I'm unsure how to /silence/ stderr in that case too
teatime just don't call .stderr, according to the docs 12:34
you do have to read both streams tho or you risk a deadlock... presumable Proc::Async is smart enough to know that / do it for you 12:35
Voldenet actually, not doing anything to the .stderr just passes the stderr to the perl's stderr 12:36
which isn't what I want :)
teatime hrm 12:38
that doesn't sound right
teatime has the sudden realization that can use Perl6 like an Expect that doesn't suck. 12:40
timotimo you just tap it and do nothing with the result, i believe 12:43
teatime it's super weird to me it outputs it to the programs stderr 12:44
Voldenet I guess it works as requested, I'm just overly pedantic about the readability
teatime: it's okay - most applications don't write to stderr unless there's /an error/ ;) 12:45
12:45 Cabanossi left
teatime well, it's ok to output various free-form debug information into stderr 12:45
that's what it's for
because you can redirect it away and get just pure "output" when that's what you need 12:46
jast it kind of makes sense that stderr goes to stderr if not accessing it means no redirect is set up
teatime kindof, yeah.
is there a null supply consumer / sink, or is {} basically that 12:47
jast: yeah, I suppose so..
just a LTA in docs I guess
Voldenet teatime: {} is interpreted as hash by default, needs that little $ somewhere
teatime oh. is {$} really the best way to do that?
Voldenet My question exactly ;) 12:48
12:48 piojo_ joined, Cabanossi joined, cdg joined 12:54 cdg left
teatime like, it seems like {$} would trip the useless use of scalar value warning 12:56
you could do -> $ {}, though ? 12:57

pochi why would using a block in map change things? 14:11

raschipi It's an undefined value that carries out-of-band information on what went wrong... 14:12
teatime so what's the answer to pochi's latest question? 14:14
Voldenet I'm not sure why using a block in map would change things, but I guess there's a difference between how WhateverCode and Block is treated
pochi m: my @x; try { CATCH { default { say "hello"; } }; @x = "4,foo".split(",").map: *.Int; }; say @x;

camelia No such method 'sink-all' for invocant of type 'Seq'

Voldenet *cough*
pochi so, sink-all makes it non-lazy?
teatime what's weird to me is map(Whateverable) ends up lazy but map({block}) doesn't? 14:22
14:22 cdg left
teatime I thought about that for the answer to "why does whateverable not raise when block does", but thought nah, can't be that 14:23
