japhb grondilu: OpenGL bindings were already in the most-wanted bindings list at github.com/perl6/perl6-most-wanted...indings.md ; what did you update? 00:29
00:30 cognominal__ left
japhb timotimo_, not_gerd: I wrote the initial versions of the Parrot OpenGL bindings. There was such a vast API to wrap that I ended up writing a regex-based C header snarfer to gather everything I needed and generate the bindings (code, data, constants, etc.) 00:31
There's just a bloody lot there.

Heather diakopter I want something alike C# "using" for disposible objects, like I don't want to care about closing file 05:09
diakopter ok; maybe do something like that example except the trait name is 'disposable' 05:10
TimToady why not just a function that takes a closure? 05:11
sub surroundX(&foo) { say "Before"; foo; say "After" }; surroundX { say "Middle" }

Heather yes, thanks.
diakopter so you could make a combinator that generates those things for particular classes
Heather TimToady though it must also work with try finally if I want to follow C# using )

TimToady or something like that

Heather TimToady I need to use variable from surroundX in closure 05:25
TimToady well, then you probably want a macro instead
Heather yes 05:26
05:26 jerome joined
quietfanatic Then it'd have to pass it as an argument to the closure 05:26
or
Heather does perl6 support macros?
quietfanatic it could be a contextual variable, like $*foo
TimToady but it would be unhygienic for your argument block to refer to a normal lexical that had not been declared, so yeah, maybe a dynvar as qf suggests
or a parameter would be cleanest 05:27

TimToady Heather: not sure quite what yer asking 05:33
Heather TimToady let me example
TimToady gist.github.com/Cynede/5159072 05:35
here is example 05:36
a bit wrong brackets I guess 05:37
though I saw grep working alike that... I need to find it's implementation 05:38
TimToady something more like: file($res[0], a, -> $fh { $fh.say( $gpattern ); } 05:39
quietfanatic What you intend to do there will work, I think.
TimToady or just file($res[0], a, { .say( $gpattern ) } 05:40
as long as file passes the handles as the first arg to the block
*handle
Heather undeclared routine 05:41
TimToady the :mod thing won't quite work like that though
yes, a bare 'a' will try to look for a routine of that name
Heather what is mod's type
can I declare it as mode... 05:42
TimToady you'll have to interpolate named args using prefix:<|> 05:43
(on the open)
Heather TimToady alike <|a> ?
TimToady at best you can pass in a pair, but named args are syntactic, and you need |$modes or some such to insert any pairs in as named args 05:44
if you pass in :a as an argument, it's just a pair
if you have a parameter that binds one or more pairs as a single argument, then it's just a data structure, not named args 05:45
so something like open $fname, |$mod is what you need there
05:45 kaleem joined
quietfanatic so, like sub file ($fname, &code, *%modes) { ... my $fh = open $fname, |%modes; ... } 05:45
right?
TimToady that might work 05:46
then you could call file with an arbitrary number of options
quietfanatic and they'd all be passed to open
TimToady you're relying on the fact that, when you pass in the arguments, it weeds out all the named args, so you're left with just two positionals, the filename, and the block 05:47
but it oughta work
quietfanatic doesn't it?
TimToady I think it will 05:48
if it doesn't, it's a bug :)
Heather how should I specify *%modes
TimToady just like that
quietfanatic You give :r or :w or stuff to file when you call it
TimToady it doesn't need any extra types, or what quietfanatic said, if that's what you're asking
quietfanatic file(@res[0], :r, { ... })
Heather works 05:49
TimToady file(@res[0], :r, :bin, {...})
quietfanatic that :r turns into :r(True)
and that gets shoved into %modes as a key-value pair
and then the | operator takes all the key-value pairs in %modes and turns them back into named arguments 05:50
05:52 SamuraiJack left 05:53 wk left
Heather quietfanatic cool ) that's becoming less verbose but I like it 05:54

TimToady you have to put the &b before the *%h

TimToady it also works good ) 06:00
TimToady now it looks better for me github.com/Cynede/ignore/blob/master/bin/ignore :) 06:08
TimToady but I think there is way to get all the lines and then check if contains $pattern 06:09
instead of making loop
stairs of the closing brackets is still being my objection to feel ugly 06:13
TimToady well, any(.lines) eq $gpattern would work
I find it difficult to read your stairs because most perl programmers use the K&R indent, not gnu 06:14
Heather TimToady I think I should back to 4 spaces -_-' because it magically makes } not that ugly 06:15
TimToady well, I'm not fond of indent styles that try to be Pythonic :)
Heather TimToady GNU is uglier, it makes double indentation. 1 for brackets, 1 for code
TimToady I'm just used to looking straight up from the bracket to see what the opening construct was for it 06:16
Heather I'm trying to be ml-ick >_<
TimToady it's sort of aristotelean, everything has a beginning, a middle, and an end :)
Heather TimToady if you already have indent you don't need it ... 06:17
TimToady well, perl won't prevent you from programming in whatever style you like, but you should just be aware that most Perl shops go the outdenting way
Heather TimToady so ... I would say most of everything with brackets go K & R way 06:18
TimToady that's the way most Algolish languages have gone
even if they only spell it 'begin/end'
Heather I heard that perl is great language to use pseudographic way -_-'
TimToady sure, and I don't deny that people's branes work differently when it comes to graphics 06:19
just pointing out that you'll be swimming upstream sooner or later, given current culture 06:20
don't want you to be shocked when someone gives you some pushback on it, is all
Heather TimToady I have ability to follow upstream code when do contributions :)
TimToady ain't asking for any more than that
TimToady is more excited to see new contributors 06:21
Heather TimToady I will be happy to be
TimToady cool, don't let anyone discourge you, including me :) 06:22

Heather :D 06:27
TimToady currently I'm waiting for this github.com/tadzik/panda/pull/37 review

Heather virtually :S 06:29

jnthn Heather: Yes, perl6 -e "say(dir('.'))" gives me what I expect
hoelzro hmm, removing the invocants fixes it 10:49
Heather jnthn it works with newer rakudo 10:50
I was using really old build
jnthn Heather: ah!
Heather yes, my fault
jnthn hoelzro: What multi are you writing?
arnsholt gist.github.com/hoelzro/5160326
hoelzro jnthn: ^ 10:51
(thanks arnsholt)
hmm
my standalone example behaves differently than my script
10:52 lumi_ joined
jnthn Any:U $class: 10:53
That looks wrong
hoelzro critique on Perl 6 style is welcome =)
what exactly is wrong about it?
jnthn Should be IssueProperty:U $class: or so
You're specifying the *invocant* type as Any 10:54
Which means you're saying "this is typed as if it was declared in Any"
hoelzro oh, I see
that makes sense
jnthn So that's why you'll get a conflict :)
hoelzro ah!
thanks, jnthn
arnsholt Shouldn't the subclass method still be more specific?
hoelzro that was my next question =) 10:55
moritz normally, subclass methods are more specific because the invocant type is more specific 10:59
if you override that, you're out of luck
hoelzro I'm still not sure why (IssueProperty : , Mu *%_) and (Any:U $class: Str , Mu *%_) are ambiguous
hmm 11:00
that doesn't look right...
jnthn arnsholt: It's the invocant type that *makes* it more specific. 11:01
hoelzro even if the invocant type is Any:U?
arnsholt And Any is more specific than the subclass?
jnthn Multi method dispatch works as follows
FROGGS jnthn: did you recognized the slowdown of rakudo since yesterday? 11:02
jnthn When you write a multi in a class, it looks up the inheritance tree to see if any proto exists above
If not, it makes one
If yes, it clones it
It then adds your candidates
So what's in the methods table is always a proto
From then on, everything works *exactly* like multi-sub dispatch 11:03
The method dispatch is just about finding the right candidate list
FROGGS: Um, I know my *branch* is slow but I didn't merge that
FROGGS: Did it get slower in nom too? 11:04
If so maybe my multi changes aren't to blame

hoelzro now that it's quiet here, I'll try asking my multi method question again =) 14:59
gist.github.com/hoelzro/5160326
here, MAIN complains of an ambiguity 15:00
and I don't understand why
jnthn Because the two candidates are tied.
Imagine you have types S and T where S ~~ T
15:00 lumi_ joined
jnthn :(S, T) and :(T, S) would be tied 15:00
Since there's no way to say one is narrower than the other. 15:01
This is the situation you've created.
But with a third type involved.
hoelzro multi method ACCEPTS($) # <- isn't the param here Any?
oh, you know, I think I see it now
jnthn Yes, but the invocant is of type IssueProperty
hoelzro the first one is (IssueProperty, Any)
jnthn Str ~~ Any, but Any !~~ IssueProperty
hoelzro the second is (Any, Str)
jnthn Right.
hoelzro ooooooh 15:02
thanks for pointing that out, jnthn !
jnthn Should you want to see how the sorting works, you don't need to read it in C any more; the md-nqp branch has it ported to (hopefully more accessible) NQP. :) 15:03
Or the spec describes it in words
15:03 brrt joined
hoelzro \o/ 15:03
does that bring a performance hit with it? 15:04
djanatyn !won ogwr
Errm, my bad :)
hoelzro sadly, I think I'm still at the level where my C > my NQP ;)
jnthn hoelzro: Yes, but in NQP the hit was very small. I need to work out why it is worse in Rakudo. 15:09
hoelzro hmm
interesting
jnthn hoelzro: Most multi-dispatches don't actually go through the full dispatch process.
hoelzro caching, I assume?
jnthn hoelzro: Those that are typed/arity determined hit a cache.
And the cache is in C.
hoelzro ah ha
jnthn Which should hide the cost.
hoelzro I wish I knew enough of the internals to help with profiling/optimization
these last few days playing around have been really fun, but the speed is drag (at times) 15:10
some tasks are more than fast enough for me
but others are *really* slow
TimToady how hard do you wish it? :)
hoelzro heh
jnthn The re-writing into NQP is to help make it easier to port Rakudo to hopefully faster places :)
colomon rakudo read a 28 meg file on my new Linux box! \o/
hoelzro I wish I could find the spare time to learn the internals well enough to help with profiling/optimization 15:11
15:11 fhelmberger joined
jnthn My only benchmark so far is "the spectests are slower"... I wonder if it's because the candidate sorting is now a bunch slower and we sort on first call. 15:11
There's no reason we can't now just sort at CHECK time. 15:12
And then serialize the result.
Which we should do for correctness anyway, since the spec says this is when circularities should be reported... :)
15:13 lumi_ left
moritz it's kinda amazing what you can use serialization for 15:16
I mean, all sorts of stuff depends on it
which you mostly notice when it's missing :-)
15:19 lumi_ joined
jnthn Yes, which makes its low bus number somewhat worrying. 15:21
timotimo is it very complicated? a lot of code? 15:23
jnthn Sort of, and not really considering what it's doing. 15:24
timotimo i only have a slight idea about how serialisation ought to work, but i haven't actually done any serialisation coding aside from simple things like serialising a tree of lists and hashes into something like json
jnthn Well, the places it gets really icky are with packages.
They're not really pure enough. 15:25
augment is similarly tricky
Rakudo handles it...to a point.
Most of the "precompilation breaks X" boil down to such impurities. 15:26
15:28 lumi_ left
TimToady linking has always been the problem child of separate compilation, even with bondage languages :) 15:35
15:35 lumi_ joined
jnthn Yeah. Linking can basically become merging. 15:35
TimToady the known problems go back all the way to Fortan common :) 15:36
which is, actually, a better name for it than "global" 15:37
jnthn Rakudo handles it by having a write barrier on objects owned by a serialization context. If you do stuff to them while compiling some other compilation unit, then that compilation unit "repossesses" the object and saves its version. 15:38
TimToady maybe we should rename GLOBAL to COMMON to attract all the old Fortran programmers :)
jnthn If two modules you load both want to do that, it can now detect it and give them to a merger.
The merger can either do something about it (it knows how to with Stash) or throw its hands up and say "no, you can't use these two together" 15:39

davidagain moritz: if you're referring to "Perl 6 and Parrot Essentials, Second Edition (O'Reilly book) (2004)" that says 2004
if not, then I'm not seeing a big obvious sign
timotimo looks like lots of stuff is rendered wrong

so I can get bootstrapped into using the REPL

timotimo: you got it 17:54
I'm an old Perl guy
I know a handful of languages well, and how to program in them
now I want to use the cool new stuff
moritz davidagain: have you seen perlgeek.de/en/article/5-to-6 already? 17:55
davidagain in particular, hyperops and related features that allow me to be more expressive and concise with my programs
nope
but I like that there's a entry in the TOC for meta-ops
I also saw something like 12 days of Perl6 a while back 17:56
is that still relevant?
moritz uhm, link?
moritz doesn't know it off hand
davidagain let me see if I can find it

raiph davidagain: a search for "hyper" using perl6now gives a nice spread of useful results with near zero false positives
davidagain thanks raiph. I tried "tutorial" on perl6now, but it didn't improve my results 18:05
let me try hyper
timotimo oh wow, perl6now is *old*
raiph davidagain: did the tutorial search show perl6maven? 18:06
timotimo: huh?
davidagain nope - but I got it under "hyper"
never seen it before
timotimo 2005/2006
davidagain the first couple hits for hyper are the advent calendar
... for 2009
raiph timotimo: hmm. i created it a few months ago...
timotimo perl6now.com/fom-serve/cache/1.html - this? 18:07
raiph davidagain: that's probably good info (i was careful about the sources searched)
timotimo: ah. no. this: tinyurl.com/perl6now
timotimo ah, ok, neat 18:08
now.perl6.org might be nice.
raiph davidagain: the only change related to hypers i'm aware of since 2009 is that, aiui, they don't recurse in to their operands 18:09
moritz not hard to do :-)
davidagain thanks raiph.

davidagain just generally concerned with figuring out whether I can trust a specific doc or not 18:10
if I see a doc a couple years old relating to a language currently under development, I get skittish
I was hoping to just be a "user" of p6, not having to dive into the dev side or map out the territory 18:11

timotimo cool, moritz :)
18:12 FROGGS joined
davidagain hey, neat, KEEP and UNDO 18:13
you guys have been busy
raiph davidagain: i'm guessing p6 isn't where it sounds like you want it to be
timotimo there's an amazing amount of stuff actually implemented in rakudo already
davidagain raiph: yeah, I'm getting that sense.
timotimo also, a lot of somewhat important stuff still missing :( 18:14
18:14 lumi_ left
davidagain I can see p6 being my new favorite language, when it's born 18:16
TimToady it has a strong heartbeat already, and a strong kick too :)
moritz just needs to learn to walk a bit faster and steadier
TimToady can't run very fast yet though :)
raiph davidagain: after following p6 since the start, and mulling what the maturity arc might look like, based on the players, culture, spec, parrot, rakudo, etc., in 2009 I guessed late 2014 as the likely timing of p6 being just about ready for the first of those focused on using first, contributing a distant second. 18:18

davidagain maybe I'll still take a whack at implementing a mini language in p6 18:40
18:40 Liz joined, Liz is now known as lismat, lismat is now known as lizmat
davidagain don't care about perf, just want to get the flavor of the syntax 18:40
except p6 likes yelling at me and telling me my infixes are stopped 18:41
jnthn Implementing a mini-langauge is probably a pretty good way to learn grammars :)
davidagain or not stopped
or insufficiently stopped
dunno
jnthn: yeah, that's the idea :)
plus, I'd like a language that does the hard parts for me
feels like p6 wants to do that 18:42
TimToady see rosettacode.org/wiki/Parse_EBNF#Perl_6 for an example parser 18:44
or STD.pm6 :)
davidagain TimToady: I'm actually looking at RC right now 18:45
one thing that sticks out at me: you have comments on the identifier and literal tokens, but they don't seem to be introduced with a comment character
what's up with that?
18:47 lumi_ left
TimToady they're introduced with a # 18:47
don't let the highlighting fool you
the point of the comments is that highlighter is getting fooled
davidagain too late
ah, I see
18:48 crab2313 left
TimToady I think at that point rakudo didn't understand \x notation in a character class, which would be another way to get around it 18:48
18:48 FROGGS joined
davidagain how do you say $#array? 18:51
TimToady generally you don't, since ranges can exclude the endpoint 18:52
0 ..^ @array
or ^@array for short
but @array.end is the most exact equiv
davidagain I like ^@array 18:53
TimToady we end up using it all the time
well, lots of the time :)
sometimes instead we say: for @array.kv -> $index, $value { ... }
rather than reindexing inside the loop
lee__ should [1,2,3].gist look the same as (1,2,3).gist ? 18:55
davidagain wait, you can do kv on @s and %s?

davidagain heh
TimToady the inside [] is a noop
LlamaRider P5 to P6 -> Porting a method that accepted both %options and a ref $options on input... Should that be a multi with signatures (*@options) and (%options) ? I guess where the % rule comes first.
davidagain I get confused with <<>> vs [] 19:01
the << looks double to me
(I know it's really supposed to be a single glyph, but I can't type it)
TimToady always uses «»
I'll bet you can :)
what is your current environment?
davidagain 73*F, 25% humidity

TimToady hmm, dunno about that as well 19:02
davidagain it's ALT+gibberish

or a macro, if I felt like it
TimToady most of us end up defining a compose key 19:03
some editors like vi have similar bindings
colomon taught his text editor that >>[tab] should be »
davidagain I'm hoping to use Padre
TimToady maybe ask jnthn++ how he types 'em, since he's on windows 19:04
davidagain or some other GUI crutch
TimToady thing is, a compose key will work with many different apps

the tl;dr seems to be "can Grammar::Tracer be plugg'd into Perl6::Grammar?" 19:41
I don't think it can, 'cus Grammar::Tracer is Perl 6 and Perl6::Grammar is nqp. but I'm not sure.
19:43 alec__ left
jnthn masak: Correct answer. But NQP has some --rxtrace support which sorta outputs similar. Bad news: it kinda bitrat at the point I did some of the changes to keep our languages straight 19:44

jnthn That one is RT'd.

that's the conservative thing to do, I think.

LlamaRider I am still stuck btw. I don't see why self.bless(*, |%opt); is recommended if you can't access the fields you declare.
masak it doesn't create any new fields in the class. 21:29
you have to declare any attributes you want in the class. if you don't declare them, they don't exist.
you don't get attributes you don't declare. undeclared attributes don't exist. they don't exist if you don't declare them.
if you want them to exist, you have to declare them. 21:30
LlamaRider :D
masak hope that helps. :)
LlamaRider so what is bless doing with its arguments? 21:31
it helps, but I am not yet reaching the "aha" moment :)
21:31 ElDiabolo left
masak bless maps any named arguments to any attributes in the class(es). 21:32

masak if the pairing comes away with attributes or named args unmatched to each other, it doesn't care much. 21:33

p6eval rakudo 1c9939: ( no output )
LlamaRider I'm thinking of a " attribute key was never declared! " error, or something on those lines 21:36
and this is also making my P5 port slightly more involved, I have to find all places the authors were doing $self->{new_secret_field_no_one_should_know_about} = 1; 21:37
and create "has" declarations for them
which is impossible for $self->{shift} = " Who knows what key this is" 21:38
masak LlamaRider: there has been talk about that kind of error.
LlamaRider: it'd have to be at runtime, though.
LlamaRider masak: runtime is quite ok, as long as it's there
masak LlamaRider: if you want objects with keys that don't really have to be declared, maybe you really want a hash? 21:39
LlamaRider Sure, am extra level of indirection always solves the problem :) 21:41
but then I am losing all of P6 OO nice-ness
since all my attributes need to end up inside that has
hash*
masak I guess you could start MOPing around, too. 21:42
and create a custom kind of class that didn't have to declare attributes.
but that's unexplored territory, I believe.
LlamaRider I don't know enough to be OOPing yet, let alone MOPing :) 21:43
masak *nod*
LlamaRider Of course I would immediately agree $self->{shift} is bad style and should've never been allowed in there in the first place.
so maybe I would port with a vengeance 21:44
