cognominal: I suppose you want the full set of hash ops, including write. But what iteration order do you want, and do you want fast Positional access? 08:08

… about another server
jferrero I I think the best would be to convince people to go to irc.perl.org but irc-hispano.org has many years and people are accustomed. 12:02

colomon tadzik: wouldn't the translation be something like method bar($value) { $!bar = $value + 2; } ? 13:03
13:04 mtk left
tadzik colomon: I really want the $foo.bar = 42 sugar 13:08
moritz colomon: that would be more idiomatic, but requires a different setter style
colomon ah 13:09
moritz tadzik: could you please incorporate Damian's clarification into S26?
colomon tadzik: seems like to do that right, you need some sort of proxy. I don't think that area has been explored very well yet
moritz I think niecza does something like that 13:10
an object on which you can define a STORE method or so
tadzik moritz: I will 13:12
re Proxy and STORE, that's still a hell lot of typing
moritz indeed
colomon tadzik: I'd argue that's a *good* thing 13:14
moritz from an abstraction POV it's bad 13:15
because it means that it encourages the programmer to offer a separate write access syntax for attributes on the one hand, and dependently computed data on the other hand
suppose you have a Square class, and you can provide write accessors for 'width' and 'area' 13:16
if you go about the usual Perl 6 way, one would look like $square.width = 3;, the other would be $square.set-areay(9) 13:17
colomon 1st: we should be tending towards non-mutable classes anyway
moritz or the other way round, depening on what the class actually stores
which the user shouldn't have to care about
colomon: agreed, but when we offer 'is rw', we should at least make it good 13:18
colomon 2nd: isn't that a terrible design for a Square class? The idea of setting the width by setting the area sounds quite wacky to me. 13:19
moritz why? 13:20
13:20 orafu left, orafu joined
colomon hmm... sort of a design smell, I think. 13:21
13:21 drbean left
colomon I mean, would you also have a "perimeter" method, and allow setting via it? 13:21
moritz why not? 13:23
tadzik just because we don't really like something doesn't mean it shouldn't be allowed, see MI 13:25
I think an easy way to write an lvalue method is desirable for some people 13:26
colomon tadzik: I like MI. ;)
moritz: can of worms 13:27
JimmyZ Is there any other languages using lvalue function/method?
moritz if I were the user of a CAD program, I'd be pretty annoyed if it would only let me the specify the size of components in exactly one way
tadzik JimmyZ: see the paste, Ruby has it easy
colomon moritz: I think the solid example is simply, how do you seamlessly replace an "is rw" attribute with methods? 13:28
tadzik a Ruby friend is looking into Perl and asked me about doigng this sort of stuff
moritz and I'd had to do all the calculations myself just to get to the format which the Square class accepts
13:29 donri joined
JimmyZ well, I didn't find what's the different from the paste 13:29
colomon moritz: sure, but if the programmer did that by writing lvalue methods for every single derived attribute on every single geometry class, he would soon be locked up in an insane asylum.
13:29 mj41 left, Trashlor1 left
moritz colomon: not every single attribute, just those that allow a bijective mapping to the object geometry 13:29
13:30 Trashlord joined
tadzik JimmyZ: the difference is that the perl6 example is wrong :) 13:30
ie it modifies bar on every .bar() call
13:30 Trashlord is now known as Guest22304
colomon moritz: so it's crucial that an area modifier should present on Square, but it shouldn't be present on Rectangle? 13:30
moritz colomon: dunno, you could always have it keep the current height-to-width ratio 13:31
colomon: it's kinda pointless to discuss if the example scales, as long as it's a valid example in a small domain, for which we should provide the necessary semantics in the language 13:32
colomon colomon: moritz: I think the solid example is simply, how do you seamlessly replace an "is rw" attribute with methods? 13:34
JimmyZ tadzik: so you want modifies bar on the first call ?
tadzik JimmyZ: yes. I want a sugar over a custom set_bar($val) { $!bar = $val + 2 } 13:36
moritz colomon: right, and not just seamlessly, but also more generally 13:37
colomon Though I dunno, I vacillate back and forth on this. Like I feel better if my language can do it, but it's a technique I really think is a bad idea in every case mentioned so far. 13:42
gotta go, off to the Owen Sound Summerfolk festival. 13:43

TimToady you can't use lvalue-ness in multi-dispatch because P6 evaluates lvalue-ness lazily 14:11
an rw method can only determine identity of the attribute; you have to use a FETCH/STORE proxy if you want separate actions

TimToady something like that ought to work, but segfaults currently
but I agree with colomon++ that it probably means you're violating Liskov constraints 14:53
JimmyZ Let q(x) be a property provable about objects x of type T. Then q(y) should be true for objects y of type S where S is a subtype of T? 14:55
TimToady yes, but it depends, of course, on how you define "property" 14:58
if you define the property of a rectangle that it has *independent* length and width, then square violates it

eiro tadzik, is this nope for me ? 17:57
tadzik if only the Perl 6 experts advertised Perl 6, we'll not have much marketing working
17:58 supernovus left
eiro tadzik, ok: i already replied to this on the french ml :) i really have to post about it :) 17:58
tadzik eiro: what's on the french ml>?
eiro but basically: french people outside the community see perl6 as a conceptual, useless toy 17:59
tadzik that's not a french-specific problem I suppose
eiro if we want to market, we have to market with a "this is for real"
tadzik, french ml -> french mailing list
tadzik and the solution for that is "look, we are building useful tools with Perl 6"
eiro: yes, I know, but what's the email on it? :) 18:00
eiro hmm ... [email@hidden.address]
tadzik, but we don't
afaik
thowe Doesn't that require actually having a complete, mature, useful tool to point at when saying "look"?
tadzik okay, I fail to follow. Is there a certain email on [email@hidden.address] criticising Perl 6, saying that it's a useless toy? 18:01
pmichaud there was a time when linux wasn't mature, but people still used it and talked about it
even as others criticized it for being a toy
eiro ok stop
thowe I'm excited about it, and I don't even have a working rakudo atm.
cognominal eiro, I think the big problem was early adopter attrition for lack of visisbility of what is really working : perl6.org/compilers/features 18:02
tadzik does any of masak++'s presentation softwares run on Perl 6?
eiro the other pb is: we have no strong experience with perl6. if users come with questions, we'll be screwes
tadzik I see
eiro i definitly have to blog on this
cognominal with the matrix, exceptations will be more realistic 18:03
eiro because i really don't want us to fuck the perl6 marketing up
tadzik if any does, we should make a propaganda blogpost about it. If none does, I'll write a presentation software this week, make it awesome, release it, blog about it, and hopefully shut someone's mouth up
eiro examples i said on the mailing list:
- where are the perl6 Dancer, DBI, ORM ? 18:04
- what about concurrency in perl ?
(perl6)
cognominal eiro, web from masak need some love
but that's a start
pmichaud just because Perl 6 doesn't (yet) have all of the features of Perl 5 doesn't make it useless.
cognominal github.com/masak/web/ 18:05
eiro cognominal, that's what i said on the ml: don't write articles: write code! help to improve existing tools
tadzik oh, the chicken-egg problem. Yeah, as long as the Top Class Perl 5 module writers won't start writing Perl 6 modules, we won't have all of the best modules
eiro we will be more credible when we will write articles
tadzik unless we bring blizkost to the state of running those
cognominal I have not read the thread yet.
eiro (because perl6 will be more credible and because authors will have real experience)
i failed to miss my most important point of view 18:06
tadzik okay people, idea
we gather all Perl 6 projects we currently have, those usable for a wider public 18:07
eiro it's not about perl6, it's about our credibility as perl6 articles writer
pmichaud
.oO( modules.perl6.org ? )
tadzik we write a series of blogposts under a label of "awesome Perl 6", or "real-world Perl 6", or whatever
eiro (i mean: french people)
tadzik pmichaud: I mean something that a non-perl6 people can clearly appreciate 18:08
maybe that means "ready to run apps"
eiro real-world-perl6 is definitly what i want to do
tadzik psyde, the one running strangelyconsistent.org may be one of them
pmichaud tadzik: "ready to run apps" wouldn't belong in modules.perl6.org ?
eiro because "real world" is the key to save us from 10 years of expectations and frustration
pmichaud in cpan (perl5), there's the entire App:: space
tadzik pmichaud: they would. But I have a feeling we need more than plain modules.perl6.org to advertise them 18:09
pmichaud for advertising them, yes. but perhaps the answer is to simply write posts about the modules that are already there. 18:10
tadzik true
pmichaud for that matter, I don't know that there's been a post about modules.perl6.org itself, or about panda.
(perhaps there has and I just don't recall it atm... my brane is still a little lagged) 18:11
tadzik you mean an advent calendar post?
18:11 jaldhar left
pmichaud any sort of blog post 18:11
tadzik maybe 18:12
thowe For the type of semi-skilled developer and user that will account for 90% of the buzz about anything a real application has its own web site with docs and bug tracking and some kind of indication that it is working and being worked on.
tadzik okay, I'm writing a presentation software
pmichaud I guess there's ttjjss.wordpress.com/2011/04/18/new...les-world/
alas, neither "perl6" nor "panda" appear in the title :-) 18:13
