kensanata Is there a more idiomatic way of writing [ map { id => $_ }, @pages ] if I need [{id=>a}, {id=>b}, ...]? AlexDaniel at one point suggested X=> but I can't get that to work. 07:12

timotimo 07:25
m: my @pages = <a b c d e>; say "id" X=> @pages
camelia (id => a id => b id => c id => d id => e)
timotimo try this, please 07:26
kensanata timotimo: Thanks. When I try it in my code, it seems that I only get id => e, the last element. Actual code right now: %context<pages> = "id" X=> @pages; -- I guess the assignment changes something? 07:30
timotimo ah 07:31
kensanata Or maybe I'm just getting the first one? Let me check.
timotimo yes, you'll want to put the RHS in parenthesis
07:32 quester left
kensanata Hm, that appears to make no difference. 07:32
timotimo let's see
m: my %context; my @pages = <a b c d e>; %context<pages> = ("id" X=> @pages); say %context.perl 07:33
camelia {:pages($((:id("a"), :id("b"), :id("c"), :id("d"), :id("e")).Seq))}
timotimo ah, you wanted an array of them, too
especially since a .Seq will only let you iterate across it once
m: my %context; my @pages = <a b c d e>; %context<pages> = ["id" X=> @pages]; say %context.perl
camelia {:pages($[:id("a"), :id("b"), :id("c"), :id("d"), :id("e")])}
timotimo m: my %context; my @pages = <a b c d e>; %context<pages> = ["id" X=> @pages]<>; say %context.perl
camelia {:pages($[:id("a"), :id("b"), :id("c"), :id("d"), :id("e")])}
timotimo not sure if you can get rid of the scalar container around it
kensanata I'm not sure whether I actually need an array. The %context stuff is going to get used for Template::Mustache. 07:36
timotimo you'll surely want to at least .cache the Seq 07:37
07:37 sena_kun joined 07:38 p6bannerbot sets mode: +v sena_kun
kensanata I don't know about the internals of Template::Mustache. But if you're saying that the result would be brittle, then I do want an array. I don't know much about the differences between lists, arrays, and sequences. Normally it just works. :) 07:39
timotimo you can think of a sequence like an iterator, except the sequence actually contains an iterator inside of it
that means at least that after you've gone through the sequence once it'll not work any mor 07:40
kensanata I see. 07:41
jmerelo kensanata: and Arrays are immutable, while lists are not.
timotimo you got it reversed, jmerelo
jmerelo timotimo: I was afraid so. 07:42
timotimo: I always do. Thanks for pointing it out.
kensanata Well, I come at this from Emacs Lisp and Java, and there arrays and lists are very different. In Perl I often get the feeling that they are interchangeable until they're not. And I never know when it's going to hit me. 07:43
I still can't reproduce my problem in a small file. Perhaps that would help me avoid the same problem in the future.
m: my @pages = <a b c d e>; my %h; %h<x> = ("id" X=> @pages); say %h<x>; say %h<x>; 07:44
camelia (id => a id => b id => c id => d id => e)
(id => a id => b id => c id => d id => e)
kensanata So this looks good and yet it doesn't work in my real code. What do I need to change to reproduce the problem?
timotimo you're still getting only one result? 07:45
kensanata No, %context<pages> = ["id" X=> @pages] works. 07:46
I'm just trying to improve my understanding, now. :)

08:21 dogbert2_ left
Xliff_ Still need to find a way to insure control codes aren't applied when I extract data from $=pod 08:22
But it works.
jmerelo Xliff_: cool! Great job!
timotimo there's Pod::To::Text, maybe it could be made to have a really-only-text output mode 08:23
until then, Pod::Walker maybe?
Xliff_ I'll look into it when I run into a burning bridge.
jmerelo timotimo: that's sorely missing. Most Pod navigation is made pretty ad-hoc
Xliff_ I've gone through so many rounds of refactoring it's not funny.
timotimo :S 08:24
Xliff_ timotimo: You mean Pod::TreeWalker?
timotimo that must be the one

timotimo *shrug* :)
Xliff_ :) :s 08:28
timotimo you're using perl6 already :D
Xliff_ LOL
Good point.
It's suddenly disturbing to relize the yield isn't as important as the ease with which you can put things together. :P
The tricky part is figuring out how to replace the actual text. 08:31
Think something like this:
"<property name="Label">OK</property>" 08:32
So it's going to be more than just grabbing the text contents. For now. I guess I can always run a regex to lower case any characters that appear before a '<' 08:33
timotimo maybe you can use the verbatim tag around the whole thing, but ... meh 08:34
Xliff_ Was thinking that, but ... I agree. meh
Implementing a verbatim pod block might be easier. 08:35
timotimo or using a heredoc instead of pod
Xliff_ shudders.
timotimo if you put the heredoc into a sub, you can use it before you define it
Xliff_ Ooh! Good point.
I think I will make it so you can specify alternative methods for both. 08:36
Oh! YUP! 08:37
I already wrote that mechanism. :D

Xliff_ LOL! Added a statusbar, but can't do it through glade. Changes should be available at the same link. 09:20
timotimo or you could interpret the control codes and turn them back into what their text would have been %) 09:25
er, i was scrolled up still
Xliff_ timotimo: LOL! I think I'm cool with using pod unless there's a conflict. 09:27
:)
And now I've also checked that you can add to a glade generated UI, after the fact! :D 09:28
timotimo have you considered using .WHY to store glade data? :P
Xliff_ ?!?
How would I do that?
timotimo well, putting the stuff into a declarator comment

ccc I want to do something like "my &op(Int, Int -->Int)" (the intuitive way to do it)
I tried subsetting without success 13:27

camelia Type check failed in assignment to &foo; expected Callable[Op] but got Sub+{Callable[Int]} (sub (Int $a, Int $b -...)

timotimo you've got it double 13:30
& already means callable
my Op &foo asks for a callable that returns a sub that fits Op
ccc timotimo: then what sigil do I use?
timotimo you need "my &foo is Callable" or "my Callable $foo"
i'll be afk for a bit 13:31
ccc m: subset Op of Callable where .signature ~~ :(Int, Int --> Int); my Op $foo = sub (Int $a, Int $b --> Int) {$a + $b}
camelia ( no output )
ccc timotimo: How do I call a scalar callable 13:32
jnthn $foo() 13:33
ccc m: subset Op of Callable where .signature ~~ :(Int, Int --> Int); my Op $foo = sub (Int $a, Int $b --> Int) {$a + $b}; say $foo(3,2)

ccc Yay!!
I better write that down somewhere it's not in the perl6 docs that I could find and I'll never remember it. 13:34
m: subset Op of Callable where .signature ~~ :(Int, Int --> Int); my Op $foo = sub (Int $a, Int $b --> Int) {$a div $b}; say $foo(3,2) 13:35

CIAvash I could not find any tests in roast for something like `join '|', <a b c>, 'd', 'e', 'f'`. Currently it flattens everything because `*@values` is used in the signature. If it's supposed to work like the join method maybe it shoud be `+@values`? 14:52
