samcv is there much overhead to calling mysub(|Seq, $other_val) 02:59
it doesn't seem to be any faster than creating new variables and then sticking them in the function 03:00
apply-pv-to-range( |.split([';','#'], 3).».trim.head(2), True )
though it could be the head part is what is slowing it down
not sure. all i know it's slower than assigning to an array and then sticking @array[0] @array[1] in there 03:01

samcv is there a way to do `my ($var1, Nil, $var2) = .split(…)` 04:01
have like placeholder variables
like i don't want to assign it to anything, just to be padding since i don't want where i put Nil
geekosaur just use a sigil 04:04
m: my ($v1, $, $v2) = 1,2,3
camelia ( no output )
samcv ok thanks
will it assign anything to $+
err i mean $
m: my ($v1, $, $v2) = 1,2,3; say $; 04:05
camelia rakudo-moar 266f34: OUTPUT«(Any)␤»
samcv m: my ($v1, $, $v2) = 1,2,3 andthen say $;
camelia rakudo-moar 266f34: OUTPUT«(Any)␤»
timotimo every time you mention $ you get a different variable
m: say $++; say $++; say $++
camelia rakudo-moar 266f34: OUTPUT«0␤0␤0␤»
timotimo m: for ^5 {say $++; say $++; say $++}
camelia rakudo-moar 266f34: OUTPUT«0␤0␤0␤1␤1␤1␤2␤2␤2␤3␤3␤3␤4␤4␤4␤»
samcv so it does assign it somewhere? 04:06
timotimo anonymous state variables, those are
geekosaur no because $ is a special variable elsewhere
timotimo oh, in a signature bind it probably doesn't assign anything, yeah
and if it does, it should probably not do that for performance reasons
geekosaur each $ is an anonymous state variable bound to the place where it occurs, so each $ is independent of the others
samcv faster than my @parts = .split(…); my $whatever = @parts[2]; my $otherthing = @parts[1]
?
geekosaur and the one in the sigil does nothing
(except consume a value)
samcv kk
timotimo hopefully it's faster, but the way i know rakudo it's probably slower :P

timotimo okay, so about a 30% difference between those two
but it seems like the first one is faster 04:15
so ... that's cool
04:16 cdg_ left
timotimo the QAST that comes out of it is pretty weird, though 04:17
it creates a scalar for the middle one that goes into a local variable 04:18
i wonder if the bindattr to the Scalar's $!value is actually needed at all?
gotta go sleep 04:19
maybe a more thorough analysis of this behaviour is warranted.
i mean the performance characteristics
not semantics or anything
samcv yeah 04:20

camelia rakudo-moar 266f34: OUTPUT«42␤True␤»
masak \o/
(in the code where I did this, I also overrode `prefix:<!>` in the same way. the result is wonderfully readable)
I love it when I go "gee, I wish this were possible", and Perl 6 rises to the challenge 06:49

BenGoldberg is thinking, I bet I could do that in C++, if I wanted. The code to accomplish that might be painful to look at, but the result would be cool. 07:05
faraco o/ 07:06
masak hm, something about it doesn't work, though
07:10 BenGoldberg left
masak oh; the above code doesn't actually distinguish a successful overriding from an unsuccessful one 07:15
I'm getting soft in later years <3
m: multi infix:<&&>(&l, &r) { { &l($^x) && &r($x) } }; say True && 42; my &has-an-e = { so $^x ~~ /e/ }; my &five-chars = { $^x.chars == 5 }; say (&has-an-e && &five-chars)("purl6") 07:17
camelia rakudo-moar 266f34: OUTPUT«42␤True␤»
masak yep; that means it didn't work :/
IMHO this is a bug we're seeing
07:20 Tonik joined
masak m: multi infix:<&&>(3, 4) { 42 }; say 3 && 4 07:28
camelia rakudo-moar 266f34: OUTPUT«4␤»
masak right.
that's probably pretty golf'd
ufobat what does $a === $b exactly mean? i think it is not checking wether it is the same "reference"? 07:36
m: my $a = 2; my $b=(4/2).Int; say so $a === $b
camelia rakudo-moar 266f34: OUTPUT«True␤»
masak ufobat: `==` means "same numerically"; `===` means "same type and value" 07:38
that is, `==` is tied to other numeric operations such as `+` and `>`
but `===` isn't; it tries to do a comparison based on type-and-value
ufobat i think == is clear to me 07:39
masak often it comes down to a reference comparison, but not in the case of Int, since Int is a value type
ufobat so === isnt working like is-deeply for objects?
masak nope
ufobat for objects ists basically is it the same object?
masak `eqv` works a bit like is-deeply, with caveats
faraco hmm, I don't really like "standards", but where can I find recommended Perl 6 coding style? 07:40
masak m: say [1, [2, 3], 4] eqv [1, [2, 3], 4]
camelia rakudo-moar 266f34: OUTPUT«True␤»
masak faraco: not sure such a style guide has ever been written; I could be wrong, though
ufobat can i say === is == or eq but without a numeric or stringy context?
masak faraco: maybe start with `perldoc perlstyle`? :) 07:41
ufobat: yeah, kinda
faraco oh, thanks
ufobat :D thanks!
masak ufobat: both `==` and `eq` do casting before comparison. `===` doesn't
faraco what is the equivalent of Perl `unlink $file if -f $file` in Perl 6? I'm stuck at f method not exist. 07:43
m: unlink 't' if -f 't' 07:44
camelia rakudo-moar 266f34: OUTPUT«5===SORRY!5=== Error while compiling <tmp>␤Undeclared routine:␤ f used at line 1␤␤»
ufobat m: "foo".IO.unlink 07:45
camelia ( no output )
ufobat .IO makes a "file" out of your string
faraco whoa nice, thank you.
ufobat so i'd say $file.IO.unlink if $file.IO.e 07:46
faraco I can't believe I missed this -docs.perl6.org/language/io 07:47

japhb masak: FWIW, IIRC the short-circuiting boolean operators && and || are coded at a "lower level", effectively acting as macros and not fully participating in (multi) dispatch. 09:08

masak japhb: yes, that quickly became clear to me too 10:48
japhb: what's not clear is where the imposibility rests, so to speak. is it by nature impossible to combine the short-circuiting semantics and ordinary multi dispatch/overriding? or is it a limitation in Rakudo as currently implemented? 10:49
also, thank you for not saying "macroish" :P 10:50
reflecting on it, it seems to be a conceptual impossibility 10:58
the two things at odds are
(a) default `infix:<&&>` codegens something that doesn't evaluate the rhs *at all* unless the lhs is truthy 10:59
(b) the user-defined multi assumes that we know the type of the rhs

IOninja I'm finished with it :) 12:12
GauravArya Thanks masak
AlexDaniel but… shouldn't programming languages evolve over time or something? xS 12:13
IOninja Nah, it's eternally perfect now. 12:14
GauravArya the data dumper output of perl6 is very different.
what does :a, :b, :c signify
IOninja GauravArya: a => True, b => True, c => True
SmokeMachine IOninja: I'm just trying to fix the role {method ^its-not-multi{}} problem

samcv err put two says in there
IOninja GauravArya: it's a different language from Perl 5.
SmokeMachine: wasn't following so not sure what problem that is :) 12:15
RabidGravy Moo!
IOninja m: if ("0") { print "Perl 6\n" } else { print "Perl 5\n" } 12:17
camelia rakudo-moar 266f34: OUTPUT«Perl 6␤»
IOninja GauravArya: ^ that would print "Perl 5" if ran in Perl 5 :)
So even such basics as whether "0" is true are different 12:18
gfldex GauravArya: see docs.perl6.org/language/glossary#i...Colon_Pair 12:19
GauravArya: colon pairs are mostly meant to be used as optional arguments but can be a shortcut to create a Pair too. 12:20

GauravArya gfldex: thanks for the doc link.. i came across this syntax, but it was in my pipeline to be looked up, one by one.. 12:23
must say, pretty neat shorthand.. 12:25
the colon pair..
IOninja Yup 12:26
samcv well i got it like 10% faster 12:27
IOninja m: dd [ :42posint, :num(65.3), :list<a b c>, :str<meows>, :hash{:42a}, :code{;} ]

samcv now in the for loop there's only one line, nested functions and such
apply-pv-to-range2( |$range-str.split('..').map( { hex $_ } ), ....
and that split can return either one or two values, depending on if it's a single value or a range 12:28
so i have a multi and redirects which it goes to

gfldex GauravArya: it's not just a shorthand. see docs.perl6.org/language/subscripts#:exists 12:30

timotimo samcv: any reason you can't .map(&hex) instead? 12:39
is that because hex is a multi that can take two arguments and map would grab two items from the iterator? 12:40

IOninja hm
GauravArya gfldex: i see. i got the %h<a b c>=<1 2 3> part.. but why the sub is defined as my %h, then the populate part, and then %h again before sub ends. didn't understand this sequence.
timotimo the last part is because they want the hash itself to be returned by the sub 12:47
m: my %h; dd %h<a b c> = <1 2 3> 12:48
camelia rakudo-moar 266f34: OUTPUT«(IntStr.new(1, "1"), IntStr.new(2, "2"), IntStr.new(3, "3"))␤»
timotimo when you just output the result of that whole assignment, it's just a list of the things you put in
rather than the hash that they got assigned into
gfldex GauravArya: In Perl * the last statement of a Block or Routine is the return value. We do have the explicite return and return-rw statements that fire control exceptions on top of returning a value. 12:50
timotimo i'm not sure "fire control exceptions" is a good way to explain that to someone who is new to the language :) 12:51
IOninja :)
12:52 GauravArya_ joined
IOninja वापसी पर स्वागत है 12:53

IOninja GauravArya_: google translate :} 12:54

gfldex timotimo: it's not but it will put something in the back of his mind that might pop up when he needs it 12:55
GauravArya_ timotimo: i need to dig deeper.. its just that there are too many new things and I can't seem to stick to one and keep bobbing around all of them.. i now need to pick some and sit with them.. 12:56
timotimo yeah, i can imagine that :)
there are a whole lot of interconnections, and places where the same underlying concept shines through, though
that could make learning progress much quicker .. maybe 12:57
i haven't had to learn perl6 from scratch for a long time :(
GauravArya_ I mean i have been doing perl5 for some time, as I use it on a daily basis on my day job.. so for now, i am starting with looking to translate stuff which i like to do, but with perl6 12:58
gfldex in that last halve year about 50% of my doc commits read: link X to Y
and there is still plenty of work to do
IOninja Personally, I found Perl 6 very frustrating when I was trying to translate my Perl 5 into Perl 6. In particular trying to pass arguments to subs. I advocate forgetting Perl 5 entirely while learning Perl 6. 13:00

GauravArya_ we don't have rakudo star for solaris, do we? 13:02
El_Che IOninja: yeah, but perl5 is the odd duck here. Most other languages behave like perl6.
RabidGravy yeah nearly everything I have made which has an equivalent in Perl 5 has been a rewrite from the ground up
timotimo giving yourself selective amnesia is a thing that humanity needs to figure out with science. we want that stuff! for reasons!
El_Che GauravArya_: no, I gave it a go (rakudo, not star) but I got stuck on libuv
GauravArya_: libuv compiled, but tests failed
RabidGravy: rewrite is something one does when looking at the code after a long time 13:03
"refactoring" :)

timotimo i imagine changing perl5 code to perl6 is scary, because you will be deleting so much 13:04

GauravArya_ guys, just one question. how do I make an account so that I can login automatically so that I could skip the robocop 13:06
timotimo for IRC?
GauravArya_ yed
IOninja GauravArya_: get a proper IRC client, like HexChat (google for it)
timotimo there's multiple stages to automatically getting logged in :)
if you're more the console type, i'd recommend weechat 13:07
IOninja the freenode web chat we have a link to on our docs site has a very annoying captcha that you always get when you're on a not-very-trusted network

Brumbazz Hi guys :> I'm trying to install perl6 on my ubuntu machine. However no matter where I look, I see I have to install Parrot(VM). My question is, why is that nessecary ? Is perl6 run in a different way than previous versions ? Thanks in advance :> 13:21
moritz timotimo: :-)
masak moritz: I read the URL and went "huh! there are parse errors in the 007 book? waitjustaminute!" 13:22
timotimo well, for one, if you're required to install parrot, you're already getting a version that's far too outdated to be of any use
moritz Brumbazz: if you find installation instructions that talk about paart, they are outdated
robertle Brumbazz: github.com/tadzik/rakudobrew is what many people use, I guess the pages talking about parrot are jhust a bit outdated....
moritz these days, Rakudo Perl 6 runs on MoarmVM
timotimo but yeah, perl6 is run in a different way than previous perls. you can run it either with our own VM, which is MoarVM, or with JVM (though there are currently problems with that if i recall correctly)
Brumbazz ah ok, thanks :> So perl6 runs on a VM like Java ? 13:24

moritz Brumbazz: they just start them on demand in the background, like Rakudo does too

cognominal hi, there is a proliferation of bots in #perl6 and #perl6-dev. Is there a page that documents them and gives a pointer to their source code ? 15:14
I suppose that now, many or most of them are written in Perl 6

tbrowder ref when: is it a bug or a known (but undocumented) rule that a bare regex adverb in front of the first slash throws an exception? 15:32
either way, i'll update the when doc... 15:33
moritz tbrowder: if you have an adverb followed by regex, you simply have two terms in a row
or rather, the adverb is parsed as a term, and the next / then as the division operator
15:33 robertle joined
moritz so yes, updating the docs on proper application of regex adverbs sounds like a good idea 15:33
tbrowder so only one term is allowed with when before the braces? 15:34
cale2 does andthen and orelse only make sense in the context of promises? 15:35
I can't figure out when andthen would make sense
moritz tbrowder: perl 6 generally doesn't allow two terms in a row

moritz mrdside_: I can't and won't debug a whole grammar for you. My advise is to test each regex individually
15:42 llfourn left
moritz because writing and debuggiing a single regex is much easier than doing it with a whole grammar 15:42
(and debugging a grammar without input data is impossible anyway, and not made easier by the use of an unfamiliar script) 15:44
Xliff Grammar::Tracer is your friend

moritz mrdside_: my impression is that the language barrier between us is simply too big 15:46
15:47 camelia left
tbrowder okay, i did not find an example. but one thing i think is misleading is the statement about the adverb can come before or after the start of the regex declaration...I don't have the line number at hand 15:47
