RabidGravy brane struggling to wake up this morning 10:15
is there a neater way of doing:
m: my %f = ( B => 1, D => 2, A => 3, C => 4); for %f.pairs.sort(-> $p { $p.key }) -> $v { say $v.key, " => ", $v.value }
camelia rakudo-moar affe02: OUTPUT«A => 3␤B => 1␤C => 4␤D => 2␤»
DrForr I've barely gotten to work. Too much sh*t going on today. 10:16
10:16 Khisanth left, richi235 left, mls left
RabidGravy that is get the key/value sorted by key? 10:16
timotimo m: my %f = ( B => 1, D => 2, A => 3, C => 4); say %f.pairs.sort( *.key )
camelia rakudo-moar affe02: OUTPUT«(A => 3 B => 1 C => 4 D => 2)␤»
timotimo no need to be so wordy in the middle part there
DrForr Also, just so I have some confirmation, is the phrase "beginning perl 5 programmer" or "beginner perl 5 programmer" more awkward? My feeling is the latter. 10:17
masak are you aiming for more awkward? :P
RabidGravy there is one less indirection of meaning in the latter 10:18
so I would use the latter as it more directly forms a noun-like thingy than the former 10:19
DrForr Asking which is more awkward. I'm being interviewed for builtinerl.com and I used the former "beginning Perl 5 programmer" in the interview, but apparently I also have an editor who feels it's more awkward than "beginner perl 5 programmer". 10:20
I don't give sufficient sh*t to fight the issue, however. 10:21
RabidGravy I think it does very much depend on the entire context 10:22
timotimo unfortunately, "the entire context" of a given event expands outwards at the speed of light 10:23
RabidGravy but if it's an interviiew then it should respect your idiom
timotimo so good luck with figuring that out!
10:23 pierre_ left 10:24 xiaomiao left
gregf_ RabidGravy: are you looking for something similar to sort_by 10:28
DrForr Shrug. It is an interview, but I'm guessing I've already spent more time mentioning it than anyone will ever spend reading that word. 10:29
timotimo %)
10:30 xiaomiao joined
RabidGravy gregf_, don't know what "sort_by" is so I don't know, but timotimo's Whatever point works fine 10:30
timotimo if you wanted more complicated instead of less, you could also: 10:31
m: my %f = ( B => 1, D => 2, A => 3, C => 4); say %f{ %f.keys.sort }:pair 10:32
camelia rakudo-moar affe02: OUTPUT«Unexpected named parameter 'pair' passed␤ in block <unit> at /tmp/2WBNhgQGlQ line 1␤␤»

camelia rakudo-moar affe02: OUTPUT«(A => 3 B => 1 C => 4 D => 2)␤»
10:33 domm joined
timotimo turns out that's a bit shorter, but just a tiny bit 10:33
RabidGravy yeah, but that is less clear IMO, it's more to find a clear idiom for the common P5 "foreach my $ky (sort keys %foo) { print $ky, " => ", %foo{$ky} }" 10:34
10:36 labster left
gregf_ RabidGravy: something similar to this: my %f = ( B => 1, D => 2, A => 3, C => 4); %f.kv.sort_by: ->$k,$v { $k } 10:36
btw, i'm not able to understand how these 3 are the same
m: my %f = ( B => 1, D => 2, A => 3, C => 4); my %f1 = [ B => 1, D => 2, A => 3, C => 4 ]; my $f2 = { B => 1, D => 2, A => 3, C => 4 }; [%f, %f1, $f2].map(*.^name.say);
camelia rakudo-moar affe02: OUTPUT«Hash␤Hash␤Hash␤»
10:36 Actualeyes left
timotimo when you're assigning into a % container, that plops the values of whatever's on the RHS into the hash 10:38
RabidGravy it would come out longer
timotimo when you assign a { foo => bar } literal, you get a hash object on the RHS, and assigning that into a scalar variable just stores the object in question
m: my %f = :1B, :2D, :3A, :4C; say %f.kv.perl 10:39
camelia rakudo-moar affe02: OUTPUT«("A", 3, "B", 1, "D", 2, "C", 4).Seq␤»
timotimo gregf_: you can't just sort a list in bunches of two without a rotor or something in between
gregf_ timotimo: when you say container, is it like some sort of a pool, like a servicemanager or somesuch?
timotimo ... service manager? 10:40
gregf_ when does the container come into the picture. or is it for GC?
timotimo no, it's a language semantics thing
m: my %foo; say %foo.WHAT
camelia rakudo-moar affe02: OUTPUT«(Hash)␤»
timotimo m: my @foo; say @foo.WHAT 10:41
camelia rakudo-moar affe02: OUTPUT«(Array)␤»
timotimo m: my $foo; say $foo.WHAT; say $foo.VAR.WHAT
camelia rakudo-moar affe02: OUTPUT«(Any)␤(Scalar)␤»
gregf_ m: my $h = { foo => 1}; say $h.WHAT
camelia rakudo-moar affe02: OUTPUT«(Hash)␤»
timotimo that's basically equivalent to having $h = Hash.new(...) 10:42
10:42 TEttinger left
gregf_ right, and is that any different from my %h = { foo => 1 } or ( foo => 1 ) or [ foo => 1 ]? 10:43
timotimo yes, quite
gregf_ or is Hash.new immutable or bound or whatever?
timotimo no, it's about what %h.STORE does
it'll hashify things
that's also why you can't just "my %foo = SetHash.new(...)" 10:44
gregf_ oh - so theres different implementations of STORE for each of those?
timotimo it'll take the pairs from your SetHash and put them info %foo one-by-one, and you end up with a regular Hash instead of the SetHash
yes
gregf_ or they've all got a base class which implements it for all?
ok
so then, one final question *forgive me for asking so many questions* :) 10:45
theres just too many ways to do the same thing. but, do they differ in performance?
10:45 kid51 joined
timotimo probably, but of course that's muddied by things like compile-time-evaluation and such 10:45
gregf_ ah - i see
10:46 jevin joined
gregf_ timotimo: thanks for clarifying! 10:47
*wonders how complex the parser for Perl6 would be*
timotimo and if one of those variants is particularly expensive, we may put in an extra optimization, or just improve the code of STORE or whatever
enh. it's okay
you can look at it in Perl6/Grammar.nqp 10:48
Zoffix huh. DrForr you specified yourself as beginer Perl 5 programmer? :S
I thought you were an expert
gregf_ timotimo: sure, thanks
10:48 wamba joined
timotimo however, during parsing it also juggles a bunch of state and data structures; all definitions are managed by World.nqp, for example 10:49

12:06 ribasushi joined
llfourn that's what I expect. constant LHS is evaluated at compile time. 12:06
RHS*
I guess an argument could be made that it should be evaluated just after compile time... If people think the added complexity is worth it. 12:08
or just after BEGIN time rather
jnthn We expect to be able to use constants while compiling though, so they really do need evaluating at BEGIN time 12:12
12:13 pierre_ joined
jnthn It is curious that we end up not updating the code to point to the finally compiled version of f afterwards 12:13
I'm really curious if it gets the other answer (as in, "works") if you precomp :) 12:14
llfourn maybe if lazy was there it would work like that?

pmurias hi 12:14
yoleaux 2 Jun 2016 20:53Z <lizmat> pmurias: this could be of interest ? zeit.co/blog/async-and-await
jnthn Or rather, an f that comes to be
Oh... 12:15
I wonder what re-defining a stub actually does
It may well be that it installs a replacement
Rather than takes over the stub
Which would also explain it nicely
12:15 jjido joined
llfourn yes. 12:16
jnthn That is, the symbol f is *rebound*, but the fake environment used for the constant won't be updated as part of that rebinding.
llfourn yes it still points to the stub 12:17
jnthn It's an interesting issue, anyway. I *think* it can be made to work, but there's multiple possible paths there and I don't immediately know which is the right one :)
I have for a while wondered if we might be able to make a better job of how we expose the "environment" to BEGIN-time evaluated things.
Because right now it's quite a costly thing to do
I suspect CORE.setting compilation spends some about of time building up those "shadow" contexts every time we run code at BEGIN time 12:18
pmurias lizmat: I can use async/await to implement gather/take, not sure how much faster it will work compared to the current method (it's something that will have to be benchmarked)
lizmat pmurias: it was just an idea that it might make life easier on you, as it would maybe take care of compatibility issues between javascript engines 12:19
this wasn't really about speed, as far as I'm concerned 12:20
pmurias you mean emitting code that will then get preprocessed by babel? 12:21
llfourn jnthn: is this in reference to those "can't call blah" when a closure is created inside a BEGIN or whatever and is called at runtime?
pmurias (babel being the javascript of the future to the current one converter)
jnthn llfourn: I thought I fixed that once... :)
llfourn looks for the ticket 12:22
lizmat pmurias: I'm not sure... I don't know enough about it
I just wanted to make sure that you were aware of that article / feature set
llfourn jnthn: from memory you were able to fix a few instances of it but not the general case 12:23

[Coke] hurm. I suppose it's -partially- spec'd, but this goes to the discussion on the quote blocker doc ticket. "if it's in 6.c-errata, but it's skipped or todo'd, is it really 6.c?" I think the answer to that is an implicit no. 6.c-errata was a snapshot in time just before the release because we didn't have time or cycles to vet every single test in roast.
I don't think it's worth changing the 6.c files directly, but we need to plan extra time before a 6.d release to clean -that- spec version up 16:16

titsuki Why Array 16:27
sorry
jnthn m: class Foo { has Str @.array; submethod BUILD(:@!array!) {} }; Foo.new: array => ["x"] # note that this works OK 16:28
camelia ( no output )
jnthn Because a @!foo parameter actually is assignment rather than binding. 16:29
And assignment is copying, and type checks element by element, as they are copied
titsuki hmm
jnthn Whereas if you put a submethod BUILD(Str :@!array) { } then you constraint that the thing already passed to the sub must already have a type Positional[Str] 16:30
*constrain
That is, a declared type
titsuki jnthn: I see. Thanks ! 16:31

my @a = "a", "b"; sub foo(Str @a) { bar(); }; sub bar() { @a.push(42) }; foo(@a) 16:32

sortiz slobo, NativeHelpers::Pointer implements pointer arithmetic, so if you use Pointer[Foo] $ptr, you can do $ptr++ to get a pointer to the next Foo. 17:26
timotimo don't we have that in core nativecall, too? 17:27
sortiz timotimo, sure.
timotimo so it should be thrown out in NativeHelpers::Pointer? 17:28

azawawi github.com/perl6/gtk-simple/pull/41 # feedback appreciated 17:42
slobo anyways, even if I paste in NativeCall::Pointer stuff in my units, it still doesn't pickup the 'succ'
this is my definition of the struct poiinter in a struct: github.com/slobo/Six11/blob/master...w.pm6#L146 17:43
and i'm trying this: my $scr_ptr = $display.screens; say $scr_ptr.deref; $scr_ptr++; say $scr_ptr.deref; 17:44
17:45 sexy-coder-girl left
slobo first deref succeeds and shows good looking data, so i think i got the struct correct 17:46

stevieb9 is it a standard in p6 to use a dash instead of underscore everywhere, even in variables? I see it all over the docs particularly in methods, and I'm wondering if long-time p6 programmers consider this an idiom across the board or not. 19:58
FROGGS stevieb: I'd call it idiomatic, yes
and is easier to type too
sortiz: I pushed some stuff so at least some tests pass again 19:59

[Coke] yes. a concerted effort was made to try to make sure everything "normal" in the spec used dashes, not underscores 20:00
it's expected that user code would follow too. (but you can do what you want, we're not your parents.)

lolo78 Hi folks, I have been trying to use SVG and SVG::Plot lately, but did not succeed to get proper SVG files. I found a talk by jnthn in which he used it. So I copied the code and tried it, but it still does not seem to work. This is one of many attempts: 20:19
my @means = (1929 => 7, 1930 => 6, 1931 => 5, 1932 => 8, 1933 => 2, 1934 => 3);
say SVG.serialize(SVG::Plot.new(
width => 600,
height => 350,
x => @means.map(*.key),
values => [[@means.map(*.value)]],
title => "TEST TEMP"
).plot(:xy-lines));
Output:
<svg xmlns="www.w3.org/2000/svg" xmlns:svg="www.w3.org/2000/svg" xmlns:xlink="www.w3.org/1999/xlink" width="600
" height="350" />
In other words, the data is not there. When I don't use the serialize method (but only SVG::Plot), it seems to produce quite a bit of data which I believe to be some form of SVG, but I can't do anything with is as it is without the serialize method. Can any one tell me what I am doing wrong? Or point me to some documentation?

stevieb9 I can't remember who (maybe Zoffix) posted yesterday a really interesting way to chain calls (haven't tested it yet). something like `.sort, .map, .reverse given obj;`. I'm noticing that there are so many ways to do things, completely trumping perl 5 20:23

mst you can do more of those things in perl5 than you think, even if they're usually idioms rather than features 20:26

stevieb9 oh, I'm very clear on that. There's a lot I don't know about perl5, but there's a lot I do use that you don't see often. That said, I'm by no means an expert. There are many things I come across that I just give up on trying to figure out what its supposed to do. I'm just finding this perl6 thing like a new Christmas toy I suppose :)

perlpilot AlexDaniel: humor
AlexDaniel sexy-coder-girl: better tell me how your IRC client thingy is going, I NEED IT 20:39

perlpilot stevieb9: yeah, hanging out on IRC helps. Especially for Perl 6 as most of the major players are active on #perl6
stevieb9 I see that. It works for me, because I love to help others, but I'm the type who takes criticism well, and can take being told "you're wrong". I also am keen to change my opinions/beliefs if something better comes along. I think I'll be happy here 20:41
mst same goes for perl5 though
the community's significantly co-ordinated via IRC
stevieb9 yeah, I've been hanging around perl5 IRC lately too. fwiw, perl5 is still, by far, my favourite lang
perlpilot mst: yeah, that's true ... you just have to pick the *right* #perl for Perl 5 ;)

stevieb9 I saw an example the other day here regarding chaining calls and have a question. Here's a dumbed down version: '.reverse, .sort given obj'. Now, this works: 'perl6 -e 'my @a = .sort given (3,1,2); say @a', but this: 'perl6 -e '.say, .sort given (3,1,2)' does not. Can someone please explain what the process flow here is? 21:22
21:22 Emeric left
perlpilot stevieb9: sure it wasn't .sort.say given (3,1,2); #? 21:23
geekosaur stevieb, both methods are applied to the object in order. they are not chained (and if they were, they'd be in the wrong order). also .sort does not mutate. so you'd get the original value say-d, then it would be sorted (the result in sink context, uselessly) 21:24
perlpilot, I'm thinking they saw discussion yesterday about how to shorten foo.x; foo.y; foo.z by using given
anyway: `.say, .sort given (3,1,2)` does: (3,1,2).say; (3,1,2).sort; # the latter should warn because the result is not used 21:26

Zoffix TimToady, just curious, did you see my question about is-approx tolerance? Unsure if you don't have time/ideas for an answer or just missed it, 'cause you had toothwork and stuff. 22:44
This: <Zoffix> TimToady: would you have time to offer a ruling on what the default tolerance to is-approx in Test.pm6 should be? Is it relative or absolute, and what value? My ideal choice would be to go with absolute at 1e-5. The specs/docs use absolute at 1e-5. And current impl uses relative at 1e-6. The ≅ uses relative at 1e-15. My more detailed plan for rewrite of is-approx: github.com/zoffixznet/debu​g/blob/...-rework.md
and both relative/absolute methods will still be available via :rel-tol<>/:abs-tol<> 22:45

stevieb9 in the following, what would I need to do before/in say() to print out the conversion of the codepoint back to the character? perl6 -e '"🍺".NFC.say'. I've tried a few random things, including $_, which clearly doesn't work. 23:12
23:12 cdg left
stevieb9 I'm curious how to go from string character to codepoint, back to string char and then print 23:13
23:13 cdg joined
sortiz slobo, One important thing: be sure that the P6's reported 'nativesizeof' must be equal to C's sizeof of your structs. 23:14
timotimo stevieb9: you'll want to encode it to utf8 or something
23:15 Zoffix joined 23:16 adu joined
stevieb9 timotimo: ahhh, of course :) this perl6 venture has me very interested in Unicode, where I've previously not had to deal with it (barely) 23:17
same with dealing with IO in :bin mode 23:18
just from what I've learned so far (which is almost nil) has me already seeing potential improvements in my perl5 work 23:19
timotimo right, it can bend your brain a bit
with the many different representations that are available and useful for different situations
stevieb9 it's like perl5 references though... once you get it, you just get it (I hope ;)
timotimo i haven't had to deal with perl5 references yet :) 23:20
stevieb9 it's a time and dedication thing. just like I'm sure many things in perl6 are 23:21
timotimo mhm 23:22
on top of that, i haven't written more than one or two lines of perl5 code
stevieb9 I can only assume that everything in perl6 is by default passed by reference, yes?
timotimo yup
stevieb9 re: your perl5, I remember you saying you haven't coded there before
for many people, (at times myself), it seems mysterious that there are perl6 writers who haven't written perl5. however, the distinction is so significant, that it makes sense. I'm glad I decided to give perl6 a new look 23:24
timotimo ah, i already told you, then
yeah, i came from python :) 23:25
sortiz m: say "$_ {.chr()}" for "🛌🎮🍺".NFC; # btw, as NFC returns a list, you can use .chr to get the character back.

stevieb9 yep, I remember you recommending pypy ;)
Zoffix I'm sure there are lots of Perl 5 coders who never wrote any Perl 4 :P
TimToady Zoffix: I don't really care much what is-approx does; I didn't write that, I only wrote ≅, which I made relative unless you're very close to 0 23:26
there's not much point in making $x ≅ 0 relative :) 23:27
stevieb9 zoffix: yes, there are :) there are also a lot of people who to this day use perl4 syntax. perhaps because they copy/pasted code from 15+ years ago

stevieb9 timotimo: you're experienced in python and perl6. may I ask which you prefer, and why, or is that too flamey here? 23:29
TimToady doesn't believe in "zero tolerance" :)
Zoffix Eh, Python is just a dialect of Perl 6, why would it be flamey? 😜
stevieb9 a dialect... I like that lol 23:30
Zoffix With slangs, it more than just a poetical statement :) You could make Perl 6 have Python's syntax, if you really wanted to :P

stevieb9 one big complaint I hear about perl6 is that there's no CPAN, and that people cite the recent leftpad fiasco while they say the current perl6 module ecosystem has the same faults (being on github et-al). Is there an official source for where this is moving to?
Zoffix stevieb9, well, those people are welcome to help build a better system :) 23:35
stevieb9, the direction is listed here: docs.perl6.org/language/modules#The..._Ecosystem (The Future of Ecosystem section)
Though there's a severe shortage of hands to do the work.

timotimo stevieb9: i haven't done anything productive in python for a long time, tbh. i pretty much switched to p6 full-time for my hobby stuff. on the other hand, i started concentrating on perl6 core development relatively quickly 23:38
23:40 bjz_ left
stevieb9 Zoffix: thank you for that. I will definitely have a look. Out of curiosity, do you (perl6 core people) get any feedback etc. from the perl5 CPAN people to create symmetry? 23:40
timotimo: thanks for the feedback. what was it that grabbed you about perl6?
Zoffix ¯\_(ツ)_/¯ I'm not core people. I just talk a lot :P 23:41
mst might know more on that. He's a real bridge between the two communities
stevieb9 I apologize for the very general questions. I just see an opportunity to get information from very informative people, so I'm jumping ;)
TimToady is glad he no longer has to control the narrative, except when he does... 23:42
stevieb9 Zoffix: perhaps you're not core, but you're very helpful anywhere I've seen you. You jump in and provide quality info, even if someone thinks you haven't looked in a direction in a long time
next time I see Matt online, I'll ask again about any cooperation 23:44
