cbk1090 Is there a way to call a method from inside the same class? 01:59
02:00 mucker left
TimToady sure, you can either do it explicitly with self.foo, or as a pseudo-attribute, $.foo 02:01
cbk1090 so foo would be the method name? 02:02
TimToady yes
that's a virtual call
if you want a non-virtual call, you'll need to store its name somewhere you can call it as a subroutine 02:03
cbk1090 Ok got it! Thanks!!!
I think the first way will work. I dont need anyting fancy
TimToady the $.foo form works with args, in fact: $.foo(1,2,3)
basically, the external API hides whether something is actually implemented as an attribute or as a method 02:04
this helps with any later refactoring in that regard
cbk1090 TimToady, This is what I now got: self.addData( $topic, $remarks); It works great! I was thinking of making addData a sub but I really wanted it as a method for my data class. 02:06

evilcubed dude i have no fracking clue what you and the bot just said 02:51
bynari He wrote some perl6 code and the perl6 bot eval'd it and returned the result 02:52
skids There are three perl6 implementations, pugs, rakudo, and niecza. Each are ready for some things, not so much for other things. 02:53
benabik perl6.org/compilers/features
evilcubed so when i write a mod_perl or run perl from the shell in the latest CentOS it's jacked into one of these compilers? 02:54

evilcubed thank you skids, bynari, and benabik for the heads up 03:08
appreciate your time
sorear evilcubed: Perl 6 is not "the next version" of Perl. 03:09
it's a fork (yes I'm revising history here)
so all the Perl stuff you're familiar with now is, and will stay for a while, Perl 5 03:11
Perl 5 and Perl 6 are being developed in parallel 03:13
run perl -V and it might say something like "version 12"
evilcubed thank you for explaining sorear 03:14
sorear perl 5 has a lot more manpower behind it, but is suffering from the legacy of a 25-year-old codebase that's shown to strongly resist extending 03:15
the idea of perl 6 is to fix the architectural issues first
perl 6 is slower and less useful than perl 5 now, but if we calculated right it should be better within the decade
it's *usable* now.
03:15 PacoAir left
sorear and arguably *more fun* to use now. 03:15
evilcubed can i chain perl 6 into mod_rewrite and mod_perl? 03:16
sorear but it IS slower, has fewer working libraries, etc
bynari mod_rewrite has nothing to do with perl, evilcubed
evilcubed anyone done it with production boxes?
sorear define "production"
evilcubed makes money
bynari And mod_perl is a nasty old module. Join us in the brave new world of the web where we have coolness like nginx with plack and starman
evilcubed can crash and burn, but makes money
bynari: ah 03:17
sorear several people here have used perl 6 for non-website business purposes
evilcubed nginx, plack, and starman?
sorear websites ... need to be fast
not much fun to use a wiki if all the page loads take a minute
evilcubed it's alright if it's a tad slow
bynari Well. nginx is a very fast, lean web server. Starman is a backend server used to run Perl web services using frameworks like mojolicious, dancer etc 03:18
Look into Dancer, plack and starman
evilcubed okay
sorear evilcubed: the usual way cool people do web apps today is to have a perl-specific server that apache connects to
bynari They're for perl 5 btw
evilcubed kinda like fast-cgi then
sorear the perl-specific server tends to either speak http (using mod_proxy) or fastcgi
bynari I don't think perl 6 is really ready for web stuff just now, or at least there's not any frameworks etc. But you can certainly do a lot of fun things with perl 6 just now 03:19
sorear bynari: there does exist at least one working perl 6 web framework, tadzik's Bailador
03:19 PacoAir joined
bynari evilcubed: Like fast-cgi, yeah. Instead of fast cgi you'd have starman, or corola, or twiggy, or any of the other servers 03:19
bynari nods at sorear
You can join #dancer on irc.perl.org to ask more specific questions about that related stuff too 03:21
I'm going a bit off-topic for #perl6
araujo well, perl 6 is _ready_ ... depends on the project or web stuff you want to do
evilcubed thank you for the heads up
i appreciate it
bynari No one's doing production stuff with Perl 6 just now, but it's "ready" for fun projects 03:22
And there seems to be some people using it for some serious'ish projects now too
But the more people that start using it for fun stuff, the quicker it'll be production ready 03:23
evilcubed i am a bench warmer
bynari :-)
evilcubed i will wait
sorear I take issue with the equation of "production" with "runs a web server" 03:25
FORTRAN is virtually never used for Web sites, but it's a living language that is very frequently used for meaningful tasks
bynari reads "living language" and pictures Frankenstein's monster 03:26
Eek. I saw a rather disturbing image of a large creature with a head that's an old computer from the 70's 03:27
sorear Perl is more the Frankenstein's monster here.
bynari And it reads FORTRAN on the screen
sorear c.f. wall.org/...pm...
Perl 6 is already a pretty nice language for one-off scripting 03:28
colomon For what it's worth, I've got two short perl 6 scripts that I've been using for $work since 2009. As well as a nice p6 tool for working with the ABC music format, another tool for reminding me when to practice music, and the GTK mandelbrot set program. The only one where the p6 implementations feel limiting is the mandelbrot set one.
sorear Perl 6's type system is designed to allow "C"-style code in Perl 6 to run fast, but these dreams have not yet been fully realized 03:29
colomon perl 6 is already quite capable as a "glue" language for scripts. 03:30
sorear also, current Perl 6 parsers are _slow_
Perl 5 can slurp 100,000 lines of code in 2 seconds on a 2GHz P4 from 2003
evilcubed Pentium 4 is pretty fast when it isn't being smothered by Flash. 03:31
sorear perl 6 ... well I was celebrating last month when I got the 4000 line standard library to parse in under a minute
evilcubed there's a lot of definition of production, please don't take "spitting out web pages" as the only definition 03:32
i didn't mean to imply that
and actually probably didn't imply that
sorear (I maintain one of the compilers so I can get away with being pessimistic, nobody thinks I'm just going to walk off :p)
ah OK.
a lot of people use "production" and rarely explain well what they mean by that.
maybe I'd understand better if I weren't 21 and a work-virgin 03:33
03:34 PacoAir left
evilcubed i noticed that last year .NET took a hit in a way, Metro was becoming very C++ friendly, warm to that type of developers. 03:34

dalek gs.hs/wip/ident: f54ade7 | au++ | Pugs/src/Pugs/ (2 files):
* Properly implement apostrophe/dash identifier name rule as per S02.
sorear yeah, I haven't really been following that closely - I'm strictly a Mono guy
I probably oughta 03:36
evilcubed Mono won't be following Metro very closely, there's no desire to create a Metro run-time clone for Linux.
sorear oh hey, au++ is coding again 03:37
hi au.
evilcubed And when M$FT doesn't offer to keep Metro and WinRT open, that basically means they aren't going to ECMA it, not gonna standardize it, will patent encumber it up the ass
so you can feel free to ignore Metro, if you are strictly Mono 03:38

sorear I wish there were a better application platform I could use... I don't want to write my own GC and native code generator 03:39

evilcubed Use whatever you want lah 03:40
sorear the need to work around delegates makes JVMs a lot less useful for me

sorear au: What is the many many parsec error? 03:45
au (x*)* 03:46
03:46 PacoAir left
au parsec guards against that form 03:46
TimToady early STD had that guard in there, but it dropped out of the cart somewhere alongside the road...
sorear STD has a "repetition of zero-width atoms" check in CursorBase.pmc, _STAR and friends 03:47
that I don't understand
TimToady well, the check is easy to understand; it's the propagation of "nullable" that is difficult 03:48
it also became less important after the LTMer finds the LT 03:49
au yeah. the way parsec checks it is to just make sure cursor position moved between each iteration of (...)*
*nod*
TimToady a la P5
but the harder you try to nail down the notion of "made progress", the harder it is to define, unless you have a language with monads :) 03:50
benabik monads++
TimToady anyway, the LTM took pressure off that to some extent, just as having an OPP in the middle layer took pressure off of having to detect left recursion 03:51

fglock yay! - @ISA works - perlcabal.org/~fglock/perlito5.html near 'package Printer;'
tadzik fglock: cool 11:58
jnthn hi tadzik :) 12:01
tadzik have a moment to talk about roles? 12:02
jnthn Sure
tadzik Within a role the has declarator always indicates the declaration from the viewpoint of the class. Therefore a private attribute declared using has is private to the class, not to the role
so says S14, and it's the only thing that rakudo does not implement right now
and the only spectest it's not running
jnthn Yeah. Hm. :)
It basically requires suppressing "undeclared attribute" checks until class composition time. 12:03
tadzik you mentioned something about that file may have been outdated, I hope this feature is not going to go away
aye
jnthn Well, we have a choice
tadzik so that's after CHECK time, si?
jnthn Well, it's kinda orthogonal to those. It's when .^compose gets called 12:04
For declarations that is BEGIN time
At the momnent, whenever we see a $!a, we go and ask the metaclass, "oh, do you know $!a?"
And if it says no, we complain
That's why attributes from roles are na issue
tadzik right
jnthn *an
Because they aren't added until composition time 12:05
Anyway, the choice we get is (1) make this work, or (2) decide that the attributes are private to roles like today, and find a way to prevent them conflicting.
The way things are today is kinda the worst of both worlds really.
tadzik I'm wholeheartedly for (1), and so is the spec, for that matter :) 12:06
jnthn *nod*
tadzik I'm no expert in OOP and roles, but that's kinda the way I'd expect it to work
jnthn OK, then let's fix it that way :)
tadzik is there something I can do?
jnthn tadzik: Well, you've probably the skills to write the patch if I tell you where to look and you're interested in doing so :) 12:07
tadzik sure thing 12:08
jnthn In rule package_def, declare a contextual where you'll store the names to check. A hash may be cheapest as then you can be sure you only check each name once.
12:08 lichtkind left
jnthn oh, er :/ 12:09
I've just realized why this is trickier than I first realized.
Code-gen depends on knowing if the attribute is natively typed or not.
12:10 JimmyZ_ joined
jnthn And we'd not know that for attributes being composed from roles. 12:10
tadzik uh
jnthn When I say code-gen, I mean building the PAST node for looking up the attribute. 12:11
12:11 lichtkind joined
jnthn Granted we can keep a list of such things and tweak them later. 12:13
jnthn will ponder it a bit 12:14
Anyway, not so simple after all..

masak tadzik: I know I've had opinions on private attributes in roles. but it's too long ago, and I'm not focused enough to remember what I thought. and it might not be relevant anymore. 12:59
but I remember liking the idea of private attributes belonging to the *role* rather than the class. then same-named attributes will never conflict.
jnthn masak: I'm leaning a bit to that too, but it's not what the spec, or tests, or tadzik's use case expect. 13:00
masak but I feat that's not going to fly, because... there's only one "attribute storage", and that's the instance. unless we do name munging, things are gonna conflict.
fear*
jnthn masak: Oh, the name issue isn't an issue really
Use the role's type object as the key we store the attribute under.
masak oh!
jnthn We'd likely hae some fallout. 13:01
But it's very doable.
masak then... for the purposes of this discussion, I'm in the camp of doin' it like that.
it's very clean.
people from the future will thank us.
it makes little sense to have attributes from dozens of roles trample on each others' namespaces.
I'll happily change the spec... I assume it's S14? 13:02
jnthn masak: I think it may be worth getting TimToady's input first. 13:03
masak anyway, today my plan is to (a) blog about the macros D1 merge, and (b) rant on p6l about PRE/POST.
jnthn masak: Also, this doesn't help tadzik's use case.
masak jnthn: oki.
what's tadzik's use case?
jnthn tadzik: ping :)
iirc though it's about factoring certain things out in to roles
In the collection types
tadzik masak: Set refactoring

tadzik :) 13:04
masak tadzik: could you be a bit specific about the use case? I'm curious.
jnthn What are you putting into the role?
And is there any sense in which exposing the shared stuff by using a private method would work? 13:05
tadzik masak: I thought %!elems and almost everything that operates on them cuold be in Settish role, and then classes like KeySet, KeyHash etc only need to implement sub register-arg
as a method, of course
it should be possible to expos %!elems througha private method, yes 13:06
jnthn Why does %!elems need to be visible in the class?
OK
tadzik I've probably tried that
jnthn Because we optimize private method calls somewhat also.
So it may well work out just fine
tadzik jnthn: it's when the class needs to overload something else than register-arg
like Str, gist, perl
jnthn OK, but I guess a private method could work?
tadzik or at_key for that matter
could, yes. I'll retry and report
jnthn method !elems() is rw { %!elems }
er, maybe don't call it elems :) 13:07
tadzik yeah ;)
jnthn It won't conflict with .elems but it will confuse the heck out of anyone
I suspect this discussion is going to end with a spec change rather than attributes from roles ending up like the spec says today, though.
tadzik right
jnthn So it's probably best not to depend on something that may be about to change.
13:10 Chillance joined
masak there's a sense in which private attributes in the role shouldn't disencapsulate out into the composed class. 13:11
this discussion is really about whether that concern weighs more heavily than the convenience of accessing private role attributes in the class. 13:12
my intuition tells me that the purity is more important than the convenience. which is why it's interesting to hear about and think about tadzik's use case. 13:13
jnthn Having just poked at the disencapsulation approach, it certainly introduces implementation baggage.
13:13 whiteknight left
jnthn Well 13:13
It breaks certain rules we like to follow
Like, predeclaration in a given scope
masak "private attributes in the role shouldn't leak outside of the role block" would be strangely consistent with "private attributes in the class shouldn't leak outside of the class block". 13:14
I guess that's the case I'm making.
jnthn Right
Which makes sense in many ways. 13:15
tadzik masak: 'twas just confusing for me that private methods work while attriutes do not
jnthn I mean, if you find two roles on the internet, and you want to compose both of them into your class, then it limits your reuse if you have to luck out on them having non-overlapping attribute names. 13:16
tadzik if you really don't want anything to conflict and so, maybe it'd be better to use delegation
why wouldn't that be a case with private meths?
jnthn Because you can presumably write a method in your class to resolve the conflict in the way you prefer. 13:17
tadzik okay, right
tadzik tries the new approach 13:20
13:26 GlitchMr joined
felher From an encapsulation point of view: Are there/shouldn't there be role-private methods, which are private to the role, not to the class? So that a role can have methods that violate some invariant of the role when used on their own? 13:31
tadzik there are 13:32
felher tadzik: great :)
felher goes reading the specs on roles again :)
tadzik jnthn: it'd seem like access to role private methods from a consuming class does not work in the setting :/

Though it doesn't actually work yet :)
masak nevertheless, \o/ 14:05
felher I like the specs opinion on roles an private attributes. If one wants a real role-private attribute, the spec says: "you may wish to declare an attribute that is hidden even from the class; a completely private role attribute (that will exist per instance of the class) may be declared like this: my $!spleen;" 14:07
I like to have more ways, even if one may be bad in most situations. 14:08
I have to admit that compared to most of you folks i am a real noob. But isn't it more perlish to allow it and say "best don't use it if you don't have too", than to remove the possibility of doing so? 14:09
masak I hear ya. 14:10
my only question is: why would you want the default to be bad, and recommend the good alternative as a social convention?
felher Ah, so you don't want to remove the old way. Its more like swapping default/non-default? 14:11
masak right.
felher Oh, then i'm totally in for that :) 14:12

tadzik masak: well, I want to twiddle with those private attributes of a role :) (see gist)
masak tadzik: hm. 15:01
tadzik I guess it's the issue of BUILD being called for the class, which doesn't then have the %!elems anywhere
so that's the same underlying issue as before, maybe
masak tadzik: if your use case is "valid" (i.e. if we're not missing something obvious here), that indicates that roles should have their own BUILD, separate from classes. I'm not sure I believe that's feasible, or even a good idea.
but in terms of scoping, it makes a lot of sense. as long as the class can have a BUILD and the roles can too. the $!a is visible within the role, so it should be possible to refer to it. 15:02
isBEKaml tadzik: you're wrapping private methods into a role and making them available through classes via a facade? :) 15:04

tadzik phenny: that doesn't make any sense :)
isBEKaml tadzik: hm, how do I say? (helper or wrapper function) 15:05
tadzik isBEKaml: they're not really "available through classes", I just don't want them to leak out for public use
I need a way to communicate between role and class that won't leak out as a public method of the eventual object
isBEKaml tadzik: exactly as I thought. :)
tadzik okay :) 15:06
isBEKaml phenny: pl en "fasada"?
phenny isBEKaml: "facade" (pl to en, translate.google.com)
isBEKaml does it make any sense? :D
funny, that's how I pronounce that word. 15:08
masak tadzik: "facade" is just an OO pattern-lingo word for "interface which presents you with a nices API than the thing it wraps". 15:09
tadzik I see 15:10
masak there are a number of related patterns in that area, with slightly overlapping meanings: "adapter", "wrapper", "facade".
isBEKaml masak: hey, I wasn't thinking of "Facade" pattern! :)
masak oh! I assumed you were.

masak I disagree. OO patterns aren't meant to be followed slavishly, they're meant to provide a starting point for building a solution that both (a) encodes important lessons from experience and (b) fits the current terrain. 15:16
to satisfy (a), you follow the pattern. to satisfy (b), you adapt it judiciously for your particular problem.
isBEKaml (b) is what is missing most of the time. Judicious application (if only that were true in most of the projects I had worked on... ) 15:17
15:19 xinming joined
isBEKaml masak: I think we are mostly in agreement in that we should *not* blindly apply these patterns. If you miss the big picture, you're working with half baked ideas (dangerously). 15:19
masak yeah, the danger of patterns is that they are applied blindly. 15:21
as with all other kinds of advice, they apply within a context. sometimes the context is different, and the advice doesn't apply. 15:23

masak aye.
this bliki article is a nice example of that: martinfowler.com/articles/lmax.html 15:25
note: they started out trying all the conventional concurrency solutions. they didn't work for their application.
so they had to sit down and actually address the problem. going outside of the normal patterns, and ending up with a much more event-driven solution, as it were. 15:26

Ulti good
masak there's still a bit of a grumbling because of the name. 16:36
people fall straight into version think when they hear "Perl 5", "Perl 6".
Ulti its more I've been googling and keep finding blogs with people moaning about lack of magical perl6 setup.exe distributions... what do you expect from something thats still fluid and under huge dev effort?
yeah I guess that is a problem
masak it's good that people are pointing out what they want from Perl 6. 16:37

lichtkind subrule prefixes are done 20:22

lichtkind do they deserve index entries?
can subrule prefixes be combined? 20:23
moritz what do you mean by that? 20:26
sorear What's a subrule prefix? 20:28
lichtkind www.perlfoundation.org/perl6/index....t#subrules 20:31
its eg the . which makes <.ws> none capturing 20:32

masak yeah.
sorear masak: I'm trying to act humorous - my feelings aren't *really* hurt. 23:16
pmurias sorear: we should integrate perlito5 and start passing perl5 (spec)tests ;)
