RabidGravy: strange output after adding provides on 2016.05 gist.github.com/azawawi/72729d6b5a...8bc0dbe5f5
RabidGravy: did you encounter such a problem?
RabidGravy nope 08:06
that's odd
something is doing "fail()" without a message 08:08
azawawi Build.pm without 'use LWP::Simple' works btw... 08:09
strange
tried adding "build-depends": [ "panda", "Shell::Command", "LWP::Simple" ]
same problem
RabidGravy looks at the Build.pm 08:11
azawawi actually to be exact even 'use NativeCall' causes that
with a bare class Build is Panda::Builder { ... }

azawawi RabidGravy: confirmed a fresh 2016.05 'panda install .' without doing a failed `panda install GTK::Simple` worked. It is a metadata corruption bug. 09:18

ab6tract i'm clearly holding it wrong, but i thought something like the above used to work 09:44
no results for 'handles' on docs.perl6
RabidGravy the way handles works it doesn't over-ridge the one it gets from 'Any' 09:46
so I don't think it ever worked

ab6tract RabidGravy: i could have sworn that at some point i was able to do `has %.hash handles Associative` but maybe it was only a dream... 10:12
but it's easy enough to get the semantics via handles <AT-KEY EXISTS-KEY ASSIGN-KEY> 10:13
10:17 donaldh left
ab6tract of course, then you need to remember <keys kv values> as well 10:17
azawawi 172 wallclock seconds after GTK::Simple refactor (classes/roles out) on 2016.05 10:18
10:19 CIAvash left
lizmat ab6tract: not sure about that 10:20
jnthn doesn't recall that ever being something that would work
timotimo i think keys kv values happens via Any, which your class likely already derives from
10:21 donaldh joined
jnthn You'd still need to delegate 'em to the right place though 10:21
lizmat as long you have a .pairs, I think all will derive ok
timotimo oh, right, you need to have the source of "what keys exist at all" in the original handles 10:23
we don't have a single underlying thing for that 10:24
like, no LOUD-KEBAB

grondilu frankly I'm not sure Python is that easy to learn. Sure, for basic stuff it *looks* easy, but the devil is in the details and things gets messy quite quick. I remember learning about its OO model and all the __method__ syntax for stuff and it seemed pretty complicated to me. 11:44
perlawhirl funny conversation to walk into... i was just discussing perl5 v. python to a guy at work 11:45
cosimo what is the __method__ syntax?
perlawhirl i'm comfortable with python, but some things would be downright difficult for a biginner... eg. var = sys.argc[1]... if you don't supply an arg it gives you one of pythons trademark ugly stack traces... followed by "Index Error", which for a beginner is very unhelpful 11:46
DrForr And I just had someone on FB ask me yesterday because I'm on "the Perl group" if I had any advice on how to learn Python.
perlawhirl i meant... argv, but my point stands
also! try re.compile('[') and look at the very unhelpful wall of garbled stack trace. whereas perl will tell you "Unmatched '[' in regex HERE<---" 11:48
11:48 kid51 left 11:49 donaldh left
grondilu cosimo: I hope I remember well but IIRC it's a special syntax for meta-method names 11:49
like __new__, __init__ and so on.
perlawhirl __repr__ and __str__, which are kinda like Perl 6's Str and gist methods 11:50
grondilu I used to be excited about python. It lasted about a month. Now I hate it. It's dull and verbose. To me it's the new Fortran. 11:51

brrt what kind of article is that, even 12:02

hmm, question
12:05 nadim left
brrt if we were to put out articles of *ahem* similar quality, but with similar ferocity, would it work? 12:05
does this work, for python, to compete for mindshare?
psch it probably would invite the same quality of comments, but more and more contrarian
i'm not really sure what "work" means here, though. will people talk about it? probably 12:06
but it probably won't motivate people to honestly examine what Perl 6 brings - or rather, only very few 12:07
but i guess that's true regardless, and putting out this kind of content definitely would increase exposure
brrt exposure is usually a good thing 12:08

RT 127573
pierrot Good morning. I had asked something yesterday and CIAvash gave me an answer but without considering quoting. Which is the p6 equivalent to p5's quotemeta?
llfourn RT #127573
synopsebot6 Link: rt.perl.org/rt3//Public/Bug/Displa...?id=127573
psch pierrot: we don't have quotemeta. interpolation of variables inside a regex depends on how you put the variable into the regex 14:49
geekosaur pierrot, in general quotemeta isn't needed (for its intended purpose at least) because the default for interpolation is to interpolate as literal string match instead of regex. (there's an alternative interpolation syntax if you want it to be treated as a regex)
gfldex i somehow feel that representing a hole in an array with Any is wrong. Nil would fit better. Nothing is more hole-like and any possible value. 14:50
14:50 Actualeyes left
pierrot geekosaur and psch : yes, I learnt that yesterday. interpolation is enabled with <$var> 14:50

psch that surprised me. i had thought :delete respects the default
ugexe Nil seems like it would muck up `is default`
this time i was beaten
lizmat psch: this feels like a bug to me 14:54
but it all depends on the semantics of :delete

gfldex if you revert to the default, the Array loses his ability to have a hole. Unless you define Arrays with defaults to be hole-less. 14:56
moritz _4d47: if you want it to keep the element alive, you can always just set it to Nil
lizmat moritz: undefine is just another way to say = Nil
moritz right
lizmat multi sub undefine(Mu \x) is raw { x = Nil }
moritz and if you want to remove an element from the middle of the list, making the higher indexes change, you can use splice
so, whatever behavior you want, there are ways to get it :-) 14:57
there simply isn't a way to make every way behave in ways that don't surprise anybody

ZoffixW RabidGravy, which RPi did you install Perl 6 on? I'm wondering whether it'll work at all with Pi Zero 17:22
azawawi is there any performance advantage to using need or require over use?
ZoffixW wants to make his A/C Internet Connected :P
azawawi, highly doubt it, since you're loading the module at runtime 17:23
RabidGravy ZoffixW, I've got it installed on both a Rev. B and Pi 2, the former is way slow
azawawi ZoffixW: so we cant use 'require' to lazily load a module anymore, right? 17:24
ZoffixW azawawi, oh, I think that'll work just fine. And yeah, in that case it'll probably be a performance advantage, since you don't have to load the module when you don't need it 17:25
17:25 vike joined
psch conditional loading isn't quite lazy loading, is it? 17:26
RabidGravy "but" any symbols defined in the module won't be known at compile time, so you may have to jump through hoops
ZoffixW Then I don't know what lazy loading is :)
psch might just be overly picky there
azawawi so github.com/azawawi/gtk-simple/blob...Simple.pm6 is a bad practice 17:27
psch i admit that "lazy loading" as "runtime loading" is probably usually used for what i called "conditional loading" just now
e.g. "when we need it, we load it"
ugexe lazy loading (like what was attempted at one time) would load the symbols and everything still
psch ...that doesn't really clarify i think
more like "when we know we are going to use it, we load it explicitly"
whereas lazy loading to me reads more as "we know we will use it eventually, but until we do we don't load it" 17:28
which isn't what <use> currently does
mostly because of RabidGravy++'s point above
Juerd I find 'lazy loading' quite vague as a term. "On-demand loading" is much clearer but I never see that used.
Maybe it's just me
psch Juerd: no, i do agree. i think that's a good alternative
the distinction of "the language user does it manually" vs "the runtime does it automagically" is what i'd but between on-demand loading and conditional loading 17:29
...that's chiastic btw :)

a Proxy would work although I read somewhere it has performance issues on v8 17:38
jnthn pmurias: A method call on a Scalar is a call on the Scalar itself; it's that a bunch of ops imply a decont on a certain argument that makes it happen on the underlying value 17:40

Xliff Right. OK. I have a class A::Base, A::A and A::B. A::A and A::B are functionally unrelated, but both inherit from A::Base 21:04
However A::B is more complex than A::A and has several "sections" I want to split into roles.
However the roles still need methods from A::Base.
What's the best way to handle that? Role parameterization?
ugexe because A::B is A::Base you should just be able to compose the roles into A::B as expected. you may ask yourself why you want to compose the parts into A::B at all if they aren't otherwise reusable or if A::B will always use the same parts 21:08

If I split A::B into different classes. A::B::A … A::B::<n>, can I still have a class A::B that wraps the A::B::x classes in an a-la-carte manner? Kinda like the perl5 "use Module qw(<list>)" 21:12
ugexe the managable chunks are typically subroutines/methods themselves
AlexDaniel [Coke]: created a new account, problem not reproduced :/ 21:13
ugexe im not sure i follow. you can `class Foo is Foo::A is Foo::B { }`
AlexDaniel [Coke]: dunno then… alright, sorry for your time
ugexe you can also `does Foo::A does Foo::B` 21:14
Xliff Right.
However I'm trying to see if I can do A::B without having it pull in all of the classes in the A::B::* space. Just the ones I need to use for a particular purpose. 21:15
I'm probably mixing metaphors.
ugexe github.com/ugexe/Perl6-Grammar--HT...TP.pm6#L14 # this is split up into parts with roles, but i can also attest its hard to follow the code path around
you are talking about dependency injection/inversion type stuff 21:17
Xliff OK, thanks. I think I at least have something to start from.

Xliff ugexe, I guess. Yeah. 21:17
ugexe you'd need to use a service locator pattern type deal to call .^add_role(whatever)
Xliff Is there .^add_class()? 21:18
ugexe ^add_parent maybe

Xliff That works. Thanks! 21:20

Thanks!
AlexDaniel Xliff: I've also mentioned LWP::Simple here: github.com/supernovus/perl6-http-c.../issues/11 22:48

kalkin- hi 23:37
is there some clever way to detect if a string consists of only unique characters?
m: "CasdfghjkC234" ~~ /.*(.).*$0.*/ 23:41
camelia ( no output )
geekosaur you probably want to prefix that with `say so`
kalkin- m:say so "CasdfghjkC234" ~~ /.*(.).*$0.*/ 23:42
geekosaur m: say so "CasdfghjkC234" ~~ /.*(.).*$0.*/
AlexDaniel space
camelia rakudo-moar 1ab1fb: OUTPUT«True␤»
kalkin- Ahh thanks
so regex is probably the shortest solution for that 23:43
AlexDaniel I don't think so
sortiz kalkin-, that fails, 'C' isn't unique.
kalkin- m: say so "CasdfghjkC234" !~~ /.*(.).*$0.*/ 23:44
camelia rakudo-moar 1ab1fb: OUTPUT«False␤»
kalkin- m: say so "Casdfghjkc234" !~~ /.*(.).*$0.*/ 23:45
camelia rakudo-moar 1ab1fb: OUTPUT«True␤»
raydiak the leading and trailing .* is unnecessary
AlexDaniel m: say so ‘abcde’.comb.Bag.values.all == 1 23:46
camelia rakudo-moar 1ab1fb: OUTPUT«True␤»
AlexDaniel m: say so ‘abcdce’.comb.Bag.values.all == 1
camelia rakudo-moar 1ab1fb: OUTPUT«False␤»
AlexDaniel that's it
kalkin- m: say so "Casdfghjkc234" !~~ /(.).*$0/
camelia rakudo-moar 1ab1fb: OUTPUT«True␤»
kalkin- raydiak: Thanks 23:47
raydiak you're welcome :)
kalkin- is going to read the docs to understand what happens in AlexDaniel example
Of course thanks to all :)
23:48 TEttinger joined
AlexDaniel it also depends on how efficient you want it to be 23:49
and whether you are dealing with long strings or not
kalkin- AlexDaniel: the normal use case should be < 100 chars 23:50
AlexDaniel … and I have a feeling that regex solution is much slower than any other
