timotimo greetings 00:00
please state the nature of your lepidopterological emergency
tbrowder__ i want to assign a function with multple args to a scalar, and then use it, but how is that done? the docs show a weird example for 2 args but it’s not clear how to practically use it. here is what i would like to do: 00:04
00:04 mcmillhj joined
tbrowder__ timotimo: hi 00:04
00:05 p6bannerbot sets mode: +v mcmillhj
tbrowder__ “my $sub = &do-something; $sub($a, $b, $c); 00:05
timotimo that's exactly how you do that 00:06
m: sub do-something($one, $two, $three) { dd $one, $two, $three }; my $sub = &do-something; $sub(1, 2, 3) 00:07
camelia 1
2
3
TimToady and you can use .assuming if you want to pre-supply some of those args
00:09 mcmillhj left
tbrowder__ ok, thanks. i need to go back and make sure i’m not making a typo 00:09
00:18 mcmillhj joined, ZzZombo left 00:19 p6bannerbot sets mode: +v mcmillhj 00:26 knation left
tbrowder__ hm, do the subs have to be declared before the reference is taken? 00:35
the subs i’m trying to reference are at the end of the program 00:36
geekosaur probably yes. otherwise you'd get a type object 00:37
tbrowder__ calling them directly is no problem
geekosaur there are ways to trip this with variables due to some things happening at compile time and others at run time, and compilation being one-pass 00:38
timotimo m: my $foo = testsub; sub testsub() { say "yes" }; $foo() 00:39
camelia yes
No such method 'CALL-ME' for invocant of type 'Bool'
in block <unit> at <tmp> line 1
timotimo m: my $foo = &testsub; sub testsub() { say "yes" }; $foo()
camelia yes
timotimo that apparently ought to work
tbrowder__ let’s see 00:45
m: my $f = &bar; $f(); sub bar() { say “yes”} 00:46
camelia yes
tbrowder__ m: my $f = &bar; $f(1, 2); sub bar($a, $b) { say “$a, $b”} 00:48
camelia 1, 2
TimToady subs are the one spot where we worked really hard to allow forward refs
tbrowder__ hm, i must have a typo, this all looks great and as expected (wanted)
TimToady because mutual recursion
tbrowder__ roger! 00:49
thanks TimToady and timotimo!
TimToady it does have to be resolved by the end of the file
tbrowder__ yes!

joy_ hello, while compiling perl6 from source on a Centos 7 machine (for which im not root, so i'm installing locally), i got an erorr 04:17

EdwardIII15 how come * under bash can both glob and work as a literal arg for some program, but not for zsh? eg. ls somedir/Downloa* && find somedir -type d -name Downloa* will both work under bash, but for zsh the latter asterisk attempts to glob and messes up the whole command, returning zsh: no matches found: Downloa* 06:57

masak ...is there a mechanism in Perl 6 similar to Java et al.'s "return another value from a `finally` block"? 08:40
(I don't have a use case for it, but I'm curious about nailing down the semantics)
my guess is that there isn't, because of how `return` works in Perl 6 as opposed to Java 08:43
domm not sure if this was discussed here, but a Perl 6 solution is missing in this comparison: github.com/drujensen/fib 08:46

masak moritz: on the topic of "should an object of that type really hold that method?", what about Label objects having a .goto method? :) 10:43
I think it's comparable to integer objects having a .times method -- it's not that it's super-wrong exactly, but it's kind of ignoring a surrounding "context" that's really doing the heavy lifting 10:44
in both the case of .times and .goto, there's an implicit runtime somewhere that does the appropriate control flow

masak moritz: not arguing for the justness of 5.times here, but -- from a Peano/Church interpretation, it's actually not completely crazy that natural numbers represent a kind of iteration/repetition 11:00
moritz there's a reason we use integers to count iterations, yes :-) 11:01
sena_kun `5.times` seems more like a stealing from smalltalk, where we have something like `1 to: 20 do: [:x | x printNl ]`. and in smalltalk there are no real categories between things, as everything is an actor && actor can do only calls.
moritz the inductive defintion of integers very closely iterations
sena_kun: I know it from ruby, but I guess ruby might've stolen it from smalltalk :) 11:02
sena_kun moritz, yes, I think they might. :)
masak yes, they did 11:03
my understanding of Smalltalk is that Smalltalk is very un-Liskovian :)
and the criterion is more like "does it feel cute today to send 1 a to:do: message? then let's do that"
this is not a criticism so much as trying to capture what it is Smalltalk is aiming for 11:04
inheritance in Smalltalk is not used for some neat/pure subset relation, but for pragmatic re-use 11:05

masak like I said elsewhere, I don't consider 5.times to be either more or less wrong than "OH HAI".say 11:14
I think if we could've done Perl 6 from scratch, then `.&say for @values;` would've been enough, and no need for a method 11:15
(not bashing methods in general; just that one) :) 11:16
jnthn If you were to assume that 5 is represented as a Church numeral, wouldn't passing a function to apply 5 times kinda makes sense? :P

masak jnthn++ has a tendency to express things exactly the way I want to say them :> 11:23
harrison jnthn: makes sense.
How hard would it be to make something like distillery for Perl6. github.com/bitwalker/distillery. A quote from the documentation: "Distillery is a tool for packaging Elixir applications for deployment using OTP releases. In a nutshell, Distillery produces an artifact, a tarball, which contains your application and everything needed to run it." 11:27

tbrowder__ hi, folks, got a question on contributing to roast: 11:35
11:36 onefst250r26 left
pmurias "OH HAI".say doesn't seem to be a good design at all 11:36
tbrowder__ i need an exhaustive bunch of pod test for the implementation of ‘#’ :numbered alias and am writing a test generator. should that generator script be in roast, too, mabe somewhere under packages? 11:38
11:38 mcmillhj left
harrison lizmat: Yes, but I actually mean, something a little bit simpler to adopt. Like I run `some-command-line --param1 --param2 --param3` and it generates a tar file with moarvm inside, modules I am using and my application. So all I have to do is upload on my server and run it. No tinkering with things and installing things on the server. 11:38
masak pmurias: that's what I'm saying. who gave strings the responsibility to print themselves? 11:40
El_Che harrison: as long rakudo is not relocatable, it would be very useful 11:41
lizmat m: "this way".put 11:42
camelia this way
lizmat m: "this way".note
camelia this way
lizmat m: 42.note
camelia 42
lizmat masak: I think it's Cool things that we gave the resposibility 11:43
masak yes, you're right 11:44
and Cool is just a manifestation of the p5 scalar concept, that some types are interconvertible
but it doesn't make much more sense for Cool to own the capacity to print itself than for Str to do so 11:45
lizmat perhaps, to me it feels like TIMTOWTDI
specifically when testing things
masak anyway, I'm not angry about this, or proposing a Grand Change -- I'm fully aware Perl 6 has never been about that kind of ideological purity
harrison El_Che: Yes, it can even be easier to choose a version of rakudo to use so that you can easily generate runnable units of the same app but for different rakudo versions.
lizmat so you're writing this long expression to test things, and than you realize you forgot the "say" 11:46
masak lizmat: aye, it is very pragmatic. my point was that `.&say` (invented later) would've done just as well, and would've made the method unnecessary
lizmat then it's nice to be able to do just '.say'
masak: fwiw, I find the .&foo syntax an abomination from the P5 days 11:47
where you didn't know whether something was intended to be used as a sub or a method
tbrowder__ never mind, i think i see some examples
masak lizmat: interesting. I kind of love it, and I don't mind at all the fluency that exists between subs and methods 11:48
in fact the sub <-> method "isomorphism" goes very deep in Perl 6
lizmat as it goes even deeper in Perl 5 :-)
yet, most attempts at MOP's try to make a difference between sub / method use 11:49
El_Che harrison: yes, but that's not an issue if rakudo is part of the package (the best situation). Now you'll need root/admin to write to a generic situation like /opt/rakudo or c:\rakudo because the rakudo path is hardcoded. 11:50
masak m: my method foo(Str $s:) { say $s }; sub bar($s) { say $s }; "this works".&foo; "so does this".&bar
camelia this works
so does this
El_Che harrison: you won't be able to run it from e.g. your home (or / if a container)
masak lizmat: Perl 6 is the only language I know where you can have both subs *and* methods inside a class. (and there's a distinction, and it kinda makes sense)
harrison El_Che: I see, I hadn't thought of it like that. 11:51
masak lizmat: but the distinction disappears if you go deep enough into the semantics, because (after all) methods are just routines that you called "on an invocant", and so not so different from subs
lizmat: I dunno, I think I've just made peace with that ;)
jnthn masak: subs in a class pretty much fill the same niche as static methods, no? :) 11:52
masak I remember being frustrated at some point that error messages considered the invocant to be one of the parameters, and so it would kind of report the parameters "off-by-one"... but I've come to accept that as a necessary sacrifice when there's no fundamental distinction between subs and methods
jnthn: yeah, guess so. except that's not how I think about it in Perl 6, but I guess it makes sense 11:53

MasterDuke the perl6 version without return is faster than perl5 for fib(35) 14:11
lizmat yeah, it takes a little while for Perl 6 to heat up 14:13
timotimo yeah, return is *really* slow :) 14:18
lizmat hmmm... perhaps we could statically determine in the optimizer that we can lose any 'return' at the end of a sub / method ? 14:20
timotimo i think we already have an opt that tries to do that
it must have bitrotted
jnthn Hm, I wonder if return control exceptions are rewritten into goto yet 14:21

AlexDaniel MasterDuke: yes but hacktoberfest is not that related to squashathons so the label needs to be added anyway 16:31

jmerelo: and then mark issues with `hacktoberfest` label 16:35
the bot will then announce here that the webhook was added, and I guess that's it?
we also need a list somewhere of all repos

Xliff Oh! I am overriding method bless there.
Got that bit from timotimo
Zoffix nqp is not user-supported. You shouldn't be using it. 18:17
Xliff: blocking off Mu.new gives a better error: gist.github.com/zoffixznet/b33a036...424c001f36
Xliff I am well aware of that.
I have signed the nqp disclaimers. It works. That's all I care about.
Zoffix Xliff: but that's exactly the point. It works *right now*. It can change at any moment and not work anymore. 18:18
Xliff I am aware of that. 18:19
Do you have a better method of overriding method bless?
Zoffix method bless(*%attrinit) { 18:20
my $o := self.Mu::bless: |%attrinit;
$o.setType('GTK::MenuItem');
$o;
}
Xliff Zoffix++ !! 18:21
moritz might be better use |c captures 18:22
more efficient, that is
not sure though
Zoffix
.oO( do `.setType('GTK::MenuItem'); later in the food chain—.new, .BUILD, .TWEAK—and leave .bless alone)
 18:23
moritz too simple
Xliff Zoffix: Tried that. BUILD does NOT work becuase of inheritance chain. setType() is only supposed to run ONCE. 18:24
same with TWEAK
Zoffix m: class Foo {}; sub (Foo() :$z) {}() 18:31
camelia No such method 'Foo' for invocant of type 'Any'

camelia Cannot resolve caller z(...); none of these signatures match:

 18:32
Zoffix Xliff: it's this coercer: github.com/Xliff/p6-GtkPlus/blob/m...em.pm6#L62
Xliff: you're not giving it a default, so it's trying to coerce the default default value of that parameter (`Any`) to that type, and since it can't that multi gets regarded as non-matching
Xliff Zoffix: Thanks! That's helpful, since I need those. It's the only time I've tried that using a named-arg. 18:33
So I guess a better way to write that would be -- "GtkWidget() $submenu = GtkWidget" 18:34
Zoffix prolly
Xliff Because I need to use a "with" construct later in the code... which should actually be in BUILD.
Thanks a lot!
Zoffix Xliff: this potentially is also a bug. You're giving `$_` to the subs, yet it doesn't appear to be set to anything: github.com/Xliff/p6-GtkPlus/blob/m...m6#L64-L67 18:35

i myself would put =begin pod and =end pod around things like =head1 21:54
and i didn't actually know you could put parenthesis (any kind) directly after the | or =
if it's just one line, you can of course leave it out 21:55

tyil timotimo: he's not online anymore 21:58
I sent him an email with a patch to solve it, and explain why I changed things around

Kaiepi is getting the terminal width and height something that'd be better off left as a library or implemented natively? 22:18
[Coke] library 22:20
wait.
japhb Kaiepi: Terminal::Print does this using tput to emit the terminal-specific sequences for this.
[Coke] I read that as 'library vs. core' not 'library vs. native'. my bad
Kaiepi oh 22:21
japhb Terminal size is a mess that is implemented by library on all posix-like OSen.
It's such a pain that we wrapped the command line tool, instead of picking a library
22:21 mcmillhj left
japhb ... and it's still an ugly mess (see github.com/ab5tract/Terminal-Print...mands.pm6) 22:22
japhb wonders if the Rakudo bug referenced in line 50 is fixed .... 22:24
Kaiepi i do it like this in Net::Telnet hastebin.com/upetelofew.pl
22:27 mcmillhj joined
geekosaur you do somewhat less; telnet isn't trying to figure out whether the user's terminal emulator is antisocial 22:27
Kaiepi wdym? 22:28

geekosaur (like, when you output a character in the last clumn, where is the cursor afterward? telnet doesn't care. Termina::Print ants to know if it's a terminal that leaves the cursor in thelast column instead of the first column of the next line) 22:28
Kaiepi oh 22:29
geekosaur this stuff gets so very _fun_… not 22:30
