comborico1611 Anyone around? 01:16
01:16 Exodist left
MasterDuke .seen Anyone 01:17
yoleaux I haven't seen Anyone around.
comborico1611 heh
MasterDuke sorry, doesn't look like it
comborico1611 I haven't seen you in here yet. 01:18
MasterDuke i'm usually only here in the evenings 01:19
01:19 Exodist joined, cdg joined
comborico1611 Want to try to answer a question? 01:19
MasterDuke shoot 01:20
01:20 troys_ is now known as troys
comborico1611 I'm wondering if the variable is the actual object, or the foo-class.new 01:21
Example:
my $variable = Foo-class.new( ); 01:22
geekosaur it's not lazy, if that's what you mean 01:23
01:23 cdg left
MasterDuke not quite sure what you mean by your question 01:23
geekosaur if you dump it out, it'll show a Foo-class.new(...) because that's the only way it knows to create a new object
MasterDuke m: my $variable = Foo-class.new( ); say $variable.^name 01:24
camelia 5===SORRY!5=== Error while compiling <tmp>
Undeclared name:
Foo-class used at line 1
MasterDuke m: class Foo-class { }; my $variable = Foo-class.new( ); say $variable.^name
camelia Foo-class
geekosaur m: class Foo-class { }; my $variable = Foo-class.new( ); say $variable.WHAT
camelia (Foo-class)
geekosaur um, not what I wanted
m: class Foo-class { }; my $variable = Foo-class.new( ); say $variable.WHICH 01:25
camelia Foo-class|81720992
comborico1611 Like is $variable the object or Foo-class?
geekosaur it should normally be the object. nothing stops some class from overriding .new in such a way as to return the class itself, but that would be somewhat odd
meanwhile that .WHICH I did shows a Foo-class object 01:26
m: class Foo-class {}; dd Foo-class.WHICH
camelia ObjAt.new("Foo-class|U62882856")
01:27 MasterDuke_ joined
geekosaur hm, that wasn't what I intended 01:27
01:28 Exodist left
geekosaur oh, right, type object 01:28
(which is not the same thing as the class itself; it's the "undefined" value for the class, as indicated by the U)
01:29 Exodist joined
geekosaur m: my $x = Int; say defined $x 01:29
camelia False
01:29 giraffe joined 01:30 giraffe is now known as Guest32325
comborico1611 So normally $variable is the object, but you can make Foo-class the object if you wanted? 01:30
geekosaur as long as you understand that is not the class itself
(this is somewhat confusing_ 01:31
MasterDuke_ do you mean object in the non-programming language sense?
01:31 MasterDuke left
MasterDuke_ i.e., my $variable = Foo-class.new kind of maps to $variable = subject, Foo-class = object, .new = verb 01:32
comborico1611 Object in the sense of an instantiation of a class.
MasterDuke_ ah, then $variable would usually be the object/instantation, yes 01:33
01:33 gfldex joined
comborico1611 Is $variable an alias for Foo-class object? 01:33
01:33 Redrield left
comborico1611 Is $variable ro, then? 01:34
MasterDuke_ kind of. could also say it's a container for a Foo-class object
geekosaur no
m: class Foo-class {}; my Foo-class $x .= new; dd $x.VAR 01:35
camelia Foo-class.new
comborico1611 Hmm. Alright. Thanks guys. Back to the book. I'm watching the screen, though.
geekosaur hm, wrong thinhg
comborico1611 I think container for the object is the most accurate description. 01:36
geekosaur well. $var is bound to a Scalar object, which is a container with something in it
the container is mutable
if you used := then you would be binding the object directly; that would be read-only, although you can re-bind with another :=
01:36 mson joined
comborico1611 If $var gets assigned to something else, what happens to Foo-class instantiation? 01:37
geekosaur if there are no other references to the object, it will eventually get garbage-collected
comborico1611 Hmm. I see. Thanks, guys. 01:38

moritz Todd_: qqx is not a function, so you can't use () 07:00
Todd_: just use it as it is in the example (qqx{...}), and it works
Todd_ $ perl6 -e 'my $msg="help me!"; my $cmd="echo $msg | notify-send -u normal -t 2000 test \"$msg\""; qqx ($cmd);'
works
$ perl6 -e 'my $msg="help me!"; my $cmd="echo $msg | notify-send -u normal -t 2000 test \"$msg\""; qqx{$cmd};' 07:01

you're creating the range object at which point it just becomes a single object (int, num, rat, Str, doesn't matter)

comborico1611 And last night on here, we determined that a variable assigned to The Constructor it's just a container not the object. Ex. my $point = Point2D.new( )
My understanding is that not everything is an object, but Pearl can internally treat everything as an object. And this is known as Auto boxing. 17:18
Perl*
Autoboxing*
If this is splitting hairs, I don't know. 17:19
17:20 ryn1x left
comborico1611 Related to this topic is how to create an actual name for an object rather than just using ClassName.new and assigning that to a variable. 17:20
17:20 ryn1x__ left, ryn1x_ left 17:21 mcmillhj joined
tyil comborico1611: what do you mean, an actual name for an object? can you give an example on how you want to use it? 17:21
mst I'm not sure how what you mean by 'an actual name for an object'
HoboWithAShotgun when i have a FALLBACK method and it's arguments are not something i want to handle, can i somehow raise the error that would have been raised without the callback?
[Coke] comborico1611: docs.perl6.org/language/mop
wander .tell lizmat "tbrowder" is working on Pod::To::Table parsing at rakudo PR#1240.
yoleaux wander: I'll pass your message to lizmat.
comborico1611 my $var = ActualNameOfObject ClassName.new( ) 17:22
mst yes, but what would that even do/mean ? 17:23
17:23 dakkar left
HoboWithAShotgun i know have multi method FALLBACK( $m ) { dosometinginteresting(); } multi method FALLBACK ( $m, *@_ ) { die "unknown mehod" }; 17:23
comborico1611 Or even better: ActualNameOfObject = ClassName.new( )
mst what is this name? why does it exist? what is it for? 17:24
HoboWithAShotgun but that is suboptimal,
tyil comborico1611: you can type your var, my Class $foo = Foo.new
if that's what you're aiming to do
you can also `my Class $foo .= new;`
17:24 setty1 joined
tyil s/Foo.new/Class.new/ 17:25
mst comborico1611: random syntax doesn't help our confusion when we're trying to understand what the thing *means* - what semantics are you thinking of?
comborico1611 this may sound snobbish, but it's not the intent. The purpose of the name of the object is to know the name of the object.
tyil mst: I asked for an example to see the context he wants to use it in, to get a clearer case of what he means 17:26
mst yeah, that would also help
17:26 mcmillhj left
comborico1611 I'm just trying to figure out the name of the object is always the same as the class. Or if the object is anonymous. 17:26
mst I don't believe objects have names at all in the sense you're talking about, because an object is a value 17:27
perl6 is fairly clear about variables having names and values not having names
comborico1611 I'm coming from C++, where we have names for objects, not variables containing objects.
Hmm. The value of the object being the address in memory of the class? 17:28
17:28 sproctor left
mst if you try and understand perl6 via things like "address in memory" you will not end up understanding perl6 17:28
also I can't say I really feel like C++ has names for objects as such 17:29
tyil are you trying to achieve something in particular with these names? 17:30
comborico1611 No.
tyil then I can't say I quite understand what you mean, sorry
comborico1611 In C++ you create an object by two things, the name of the class (type) and the objects name. Ex. Time t; (Time is the class and t is the object.) 17:32
tyil in perl 6 you can do the same, my Time $t;
(also, that doesn't create the object, you'd need a `new` for that in c++, no?) 17:33
comborico1611 The constructor is called implicitly. 17:34
17:34 domidumont joined
tyil afaik, there's no implicit constructor call in perl 6 17:34
the shortest you can get is `my Time $t .= new;`
comborico1611 I see. But $t is not the object, but a variable containing the object. 17:35
(Or so I was told last night.) 17:36
moritz most method calls ignore the container, and go right into the object
tyil that's probably going in deeper than I know of, you might want to ask a core rakudo dev for that
perlpilot comborico1611: have you read docs.perl6.org/language/containers ? 17:37
mst comborico1611: in C++ can't you still later do 't = new Time(...)' or whatever the syntax is? 17:38
comborico1611 The docs are confusing. 😯
tyil heh
17:38 Cabanossi left
comborico1611 Mst, yes. 17:38
perlpilot comborico1611: well ... at least they match life in that regard. ;) 17:39
comborico1611 Haha.

Fix spelling typo
synopsebot Link: doc.perl6.org/language/variables
mst comborico1611: right, so it's as I remembered - C++ is the same, effectively, and perl6 just makes the distinction more explicit
17:39 Cabanossi joined
mst if you can change the value of the variable t to a different instance, then the C++ variable t isn't the object either 17:39
tyil moritz: now there's two App::MPD::Notify on modules.perl6, and they both show they were last updated last month, with the .git dir :( 17:40
mst it's a variable that happens to currently have a value of a particular unnamed object instance
comborico1611 But seriously I'm trying to get through this beginners book. And often when I go and read the docs, there are operators I'm not aware of. For example // or ===. Then, I have to go look those up. And I don't want to. I would rather focus on the book then go down the rabbit trail
tyil which beginner's book are you reading? 17:41
perlpilot
.oO( Perl 6 -- it's full of rabbits )
comborico1611 Think Perl
tyil does it not explain the examples in enough detail? 17:42
comborico1611 Mst, you could be correct. But I don't remember ever running into any code in my C++ book that would indicate that the 't' was rw.
mst comborico1611: but you just told me it was 17:43
comborico1611 No.
mst 't = new Time(...)' # you said yes to that, how is that not rw?
comborico1611 I'm actually a beginner programmer. I've only read one book on c++. I thought you were referring to another way of creating a object not reassigning it.
17:43 domidumont left
mst ok, so, if you don't understand C++ properly and I don't understand C++ properly, then we're probably best not trying to use C++ to try and understand anything else 17:44
17:44 dugword joined
comborico1611 lol. I I think I understand it properly. 17:45
perlpilot comborico1611: newbies always think they understand stuff when really they don't quite :)
mst if you can't tell me how variable assignment works, then I don't think it's going to be useful to us :)
17:45 domidumont joined
tyil comborico1611: if you can supply us with a task you're trying to achieve, we might be able to assist you in getting you what you want 17:47
if the docs are unclear, that too would be appreciated to inform, then we can try to improve it
mst yeah, I've still not worked out what this mythical 'name of an object' would actually be useful for if it existed
comborico1611 Haha. Yes. Thanks for trying. 17:48
mst note: same "I'm not trying to sound snobbish/etc." caveat applies to my comments too
17:49 dugword left
tyil we're all here to help eachother, so I think that's implied :> 17:49
mspo you mean like a $this ?
comborico1611 I'm not saying the docs are unclear as they are written for someone soley to use learn from. But from the perspective of someone using another's source, going and looking up a term only to see code they don't recognize, that is going to be unclear. 17:51
tyil I think that could be attributed to the source having unclear or incomplete examples 17:52
comborico1611 Roger that. Much appreciated.
17:52 mcmillhj joined
mst I suspect at least in part the problem is that perl6's features interlock to an extent that makes it *really* hard to write an introduction that doesn't end up depending on things it hasn't had a chance to explain yet 17:52
17:52 releasable6 left
comborico1611 Yeah, I don't expect the docs to line up with a book. 17:52

mst note that I've attempted to do a completely synthetic intro to perl5, and aaaaaaaaaaa 17:52
tyil comborico1611: I'd suggest you just read the book and ignore the parts that aren't quite clear, hope that everything will be explained in due time, and after that look up things as needed in the docs 17:53
comborico1611 Synthetic? Intro to p6 for p5 users?
tyil or ask around here to see if anyone might have a simple solution
perlpilot comborico1611: btw, when you figure this stuff out, maybe write a blog post or some docs or something to help the next guy :)
mst synthetic as in synthetic proof 17:54

mst where you don't rely on a concept until you've introduced it 17:54
comborico1611 Perlpilot, yes, I'm taking very detailed notes of my experience through the book.
mst think e.g. Euclid's Elements
tyil perlpilot++ more perl 6 blogs to help people realize its usable and help beginners understand it are always nice
comborico1611 I plan on submitting a review.
17:55 nadim left
comborico1611 Mst, i see. 17:55
Alright guys. Off to lunch.
mst because basically that's what you sound like you want, and, well, I agree, but also I'm not good enough to make it happen for perl5 let alone perl6
perlpilot tyil: "ignore the parts that aren't quite clear" reminds me of reading LoTR. I read them when I was 8 or 9 then again as an adult. But as an adult I was incredulous that I read and understood some of the words Tolkien used. I'm pretty sure my 8 year old self just glossed over the big words (if they couldn't be figured out from context) and just kept on reading. 17:56
tyil its what I often do when I find something I don't quite understand, hoping for it to be explained shorty afterwards 17:58
then go back to see if the block I was reading is more clear now

geekosaur you aren't assigning, you are passing named parameters whose names are the fields to be initialized 21:06
