.tell jnthn would be interested to know how you see Supply.emit being fixed so that it can take a single Range.new and *not* iterate over it 04:24

lizmat .tell jnthn *and* keep the \msg signature for so that we emit to the supply whatever is passed to the method verbatim 04:25

ShimmerFairy ChoHag: my first guess is that since (Bar but Baz) is a run-time mixin, having a type constraint of a run-time nature probably isn't a good idea :) 04:30
ChoHag Other than prefixing the Signature with ::?CLASS:D:, how can you specify that a method is only to be called on an instance, not a type (and vice versa)? 04:31
ShimmerFairy The :D smiley only allows instances, and the :U smiley only allows type objects (:_ allows either, and in most places is the default smiley) 04:33
I don't think there's another way beyond :D/:U , as far as I know. 04:34
ChoHag Yeah but emacs thinks ::? opens a quote so my syntax highlighting and autoindentation gets screwy. 04:35
04:35 khw left
ShimmerFairy ChoHag: oh, you can use the class name in place of ::?CLASS 04:36
ChoHag Also it seemed like the kind of thing there'd be a syntax for.

zacts so I've heard rumors that a first actual stable release of perl6 may happen this year? 04:39
and would that be the specification, or would it be the rakudo implementation of it, or both?
lizmat both 04:40
ChoHag Yeah but then they decided to reimplement some core features, as developers are wont to do.
lizmat ETA Christmas 2015
zacts nice nice
so perhaps I could contribute by learning perl6, and porting and writing modules
lizmat zacts: that would be an excellent plan!
ChoHag Christmas here happens in January, so you missed that boat. 04:41
Or looking at it the other way, you get an extra 2 weeks (Jan 7th).

ChoHag zacts: TBD it does look from the sidelines that this year is possible. 04:42
TBH
But on the other hand, I've worked on a lot of projects of various types and I don't think one has ever met any date it scheduled. 04:43
On the gripping hand, porting wouldn't hurt. 04:44

ShimmerFairy Honestly, it surprised me when Larry announced specific dates for a rakudo release candidate in Sept., and the first stable release of Perl 6 + rakudo on Christmas. In some ways it's still surreal for me that there will be a point where 6.0.0 is declared "complete", and soon-ish :) 04:46

Ven nine: okay. I'll fix the test in that file then 07:27
07:30 laben joined
nine Ven: the rules are actually quite simple now: we iterate over the thingy we got passed. for $whatever { ... } will iterate over $whatever, regardless of how that thing looks, i.e. $whatever.elems iterations. for $foo, $bar { ... } will iterate over the list ($foo, $bar), i.e. two iterations. 07:30
laben hello p6'ers
Ven nine: seems I was getting it with irclog.perlgeek.de/perl6/2015-08-23#i_11103320 then. thanks 07:31
nine If you really mean it, you can use for (@whatever,) { ... } to have only one iteration. Whyever you would want to do that... 07:32
Ven: yes, indeed! And it doesn't only litterally mean .map. It _is_ map. It gets compiled to a .map call. 07:34
laben nine: i think i got a working binary hyper impl that doesnt consume twice, need to test it, got some test files other than s03-metaops/hypers ?
ShimmerFairy nine: I think it would also be helpful to spread the idea that for (@whatever,) { ... } is best spelled given @whatever { ... } :)
nine laben: not that I'm aware of. I would love to have a look at your implementation, since I already started working on one myself. 07:35

laben nine: i think i got an off by one error in here, wont be easy to spot. it's only missing the Whatever lengthening and a good round of debugging 07:37

07:47 salv0 left, salv0 joined 07:49 rurban joined
nine laben: I think the whole implementation could be simplified a lot by writing a special anonymous iterator class that knows how to generate more values if needed after exhaustion 07:49
so you only need one loop in the function and it's just an until $left-ended and $right-ended {...} 07:51
laben nine: well, i dunno how to do that XP, you can do the honors unless you want to concentrate on reducing test files failures
nine would also get rid of a lot of the duplication

laben also btw i dont think there's a single test for the Whatever-lengthening stuff 07:52

jdv79 at least that article wasn't overtly negative or aggressive iirc - i read it a while ago 09:10
ShimmerFairy jdv79: I don't think so either, it's just that an article all about why someone won't even give Perl 6 a chance isn't very useful to me, or many others here :) 09:12
synbot6 Link: rt.perl.org/rt3/Public/Bug/Display...?id=125682
jdv79 sure. but its nice that's its largely benign.
ShimmerFairy Of course. I'm glad that it's a reasonable explanation of why this one guy isn't particularly interested :) 09:13
09:13 simcop2387 left
labster ShimmerFairy: I tested a case where we'd use all native ints on the reasonable-sized cases, and Int outside it, but that seemed to be even slower. If you have a better suggestion -- maybe limits to year size, I wouldn't mind hearing them. 09:13
ShimmerFairy labster: I can take a look at it later, I just didn't see why the native ints were replaced at first :) 09:14
labster What I got from the article was "I fell in love with Perl 5, and Perl 6 doesn't touch my feels in teh same way".

laben nine: i fixed my impl, the problem was exactly what i thought. now it passes the same tests as the existing impl. there's only one other problem: when returning, it attempts to recreate the type it originally got. In case of Seq, what do we return? 09:15

nine laben: in deepmap I resorted to List for that reason 09:22

laben nine: there's no hurry as it does not passes more tests than the existing one and i like your idea more, but i think it would be easier for you if you use the DwimIterator only for the second part, so that you can do the checks as in my impl 09:27
nine Getting rid of separate parts is most of the charm of my idea :) 09:28
laben nine: ofc if you prefer to progress on other glr matters, i'll continue to work on this and try to fix bugs and implement the Whatever stuff

jnthn On those who are trying to figure out the single arg rule, I think you can understand it entirely in terms of "for" 09:32
for X { Y } ==> X.map(Y)
uh, well, with the block of course :)
But the X is the single argument. How will .map interpret it? That's the answer.

jnthn Well, it's intentional at least
my @a = eager ...; # we don't want to immediately produce all values only to go on and copy them to @a, we'd rather produce them all direclty into @a
moritz with that, the "try" in try { eager map { die }, 1 } won't catch the exception
nine Would be nice if we could detect sink context here... 11:28
jnthn That should work 'cus try should force evaluation.
Well, trouble is that isn't actually a sink context
Because we have to return the result from try
laben nine: now it's another, "say (1..3).map(*.succ) >>~<< ('B'..'H').map(*.pred)" would throw (as specced) on existing impl, yours silently does >>op>> (or equivalently <<op>>) 11:29

timotimo then you await for Promise.any($timeout, $completed) and if after that the state of $completed isn't Kept, you flip the "abort" switch 12:01
_itz_ ok thanks
timotimo good luck :) 12:02
if you have something that gives you a Supply, you can usually close your tap on it and that may cause a proper abort. for things like async I/O. not sure about that, though 12:03

timotimo i'd argue it's not really that
if you're an async line reader for a file and your only subscriber tells you "i'm not interested any more", then it's your choice if you cancel or keep going 12:07

what's the connection with List and Seq? 12:36
moritz nine: IMHO eager should return a List, not a Seq
nine masak: deepmap is implemented using an iterator and supposed to return the same type of object that it is iterating over (mostly List or Array). So I create a List or Array for the results using .from-iterator. But it has to eagerly process, so I .eager the List and suddenly return a Seq. 12:38
jdv79 doesn't .list on a Seq get you an eagerly produced List (and memoized)? 12:39

jdv79 [Coke]: got your list of questions set? 13:02
jnthn nine: What's tricky about it, ooc? It should just be creating a fresh IterationBuffer, passing it to .push-all of the Iterator, then binding it to $!reified of a new List. 13:10
13:13 rmgk_ joined, rmgk left, rmgk_ is now known as rmgk
nine jnthn: it's tricky if you try it with high level constructs. 13:14
jnthn nine: Maybe List.from-iterator(the-iter).eager should do it 13:15
nine: That is, we make .eager on List and its subclasses mean "eagerify *yourself*"
nine jnthn: that's what I had there originally until I discovered that the eager returns a Seq 13:17
jnthn nine: Yeah, I'm thinking of chaning that
*changing
.sink returns Nil 13:18
.hyper/.race return HyperSeq
.lazy returns Seq
So it's not like there ain't precedent for .eager not returning something other than Seq ;)
nine That was just 4 negations in a somewhat short sentence... 13:19
jnthn Sorry, still a bit tired :)
[Coke] jdv79: I've had like 3 questions submitted. No, I'm not set at all. 13:20

[Coke] thankfully, that's not until Friday.
jnthn pink_mist: Yes :) 13:21
pink_mist: no wait, there's precedent for .eager *not* returning Seq :)
pink_mist I assumed that's what you meant yes, but it could be parsed the other way :P 13:22

b2gills Originally I thought something like ｢A >>OP<< B｣ just stopped when the shortest of the two lists ran out of elements. 15:59
16:01 araujo_ left
laben b2gills: it's specced to throw if they arent of the same length. if you point the hyper to the shortest one, it will instead work until the shortest end. viceversa, you point it to the longest and it works until the longest runs out 16:01
b2gills It will extend it out, which may not be what you want, and yes I know that now 16:02
laben if you point to both, it will automatically do up to the longest
b2gills What if you want it to not extend
laben point the hyper to the shortest 16:03
sorry i got it backwards
16:03 Ven joined
laben if B is shorter, A >>op>> B will lengthen B while A <<op<< B will shorten A 16:04
b2gills The way it works now ｢<<OP<<｣ ｢<<OP>>｣ ｢>>OP>>｣ are quite a bit different than ｢>>OP<<｣ 16:05
laben >>op<< is just stricter, works only if both sides have the same length
b2gills I know that, and it isn't very useful
If you think of >>OP>> as *stop* when the left is out of elements and <<OP<< as stop when the right is out of elements then >>OP<< would be stop when either is out of elements ( and would be more tenable in a lazy list world ) 16:07

nine The only GLR comment in Array.pm is about method plan, and I have no idea what its purpose is.
17:47 rurban joined
jnthn nine: .plan should push to the end of $!future in $!todo (and if there's no todo, or no future, create it as needed) 17:47
.oO( "this array has no future!" )
nine I cannot find any place where this would be called? 17:48
laben jnthn: what do you think about this? [18:08] <b2gills> If you think of >>OP>> as *stop* when the left is out of elements and <<OP<< as stop when the right is out of elements then >>OP<< would be stop when either is out of elements ( and would be more tenable in a lazy list world )
jnthn nine: It's a public API method 17:49
laben: I think that's what Z is for :) 17:50
(And Z is also lazy)
laben jnthn: but Z is lazy, while >>op<< is eager
jnthn Note that >>+<< on a native array will end up with a fairly different implementation eventually also, to provide access to CPU SIMD stuff 17:51
And so we want semantics that'll work out well there too
nine: I...hope we have tests for it ;) 17:52
nine jnthn: nope, not a single one it seems
jnthn eek
Guess we should write some :)
nine lots of hits for "plan" in t/spec, but all about test plans (or interplanetary matters)
17:53 Ven left
nine Folks we're down to 120 failing files 17:53
17:53 TEttinger joined
laben jnthn: which means? >>op<< doing the current thing (throwing if sides have different length) or the other thing (stopping at the shortest one, independent of side)? 17:53
17:54 andreoss joined
laben stopping at the shortest one ==> stopping when the shortest ends 17:54
it would indeed be symmetric with <<op>> stopping when the longest one ends 17:55
17:55 llfourn left 17:56 andreoss left
jnthn laben: I think throwing when they're not equal is the right thing here 17:57
It makes you think whether the auto-exend semantics is actually the right thing 17:58
*extend
I guess TimToady++ will backlog this at some point and give the idea another look over though :)
dinner &
laben mh, but there wouldn't be an eager way to stop when the shortest one ends unless you know the side 17:59
masak nine: er, can you do `next LABEL` if -n is just .map ? 18:08
er, I mean `next LINE` 18:09
moritz jnthn: the 'for range' optimization probably needs a second look; I've done s/FOR/map/, but it still looks at infix:<,> which I think we don't use anymore 18:17

jnthn I'll get to it if nobody else does :) 18:23

jnthn yowser, so code duplication
FROGGS nine: aye 18:31
jnthn FROGGS: Is there a way we can just create a unique label that will never match and use it as the default if no label is supplied?
FROGGS jnthn: do you have a better idea?
hmmm
jnthn FROGGS: Or since it just compares objects, just Mu will do, no?
FROGGS aye
jnthn oh, and you've a nasty bug 18:32
FROGGS O.o
jnthn $label is a lexical
And classes are not closures
FROGGS ups
jnthn $label needs to be given to the constructor and addressed as $!label
No worries. But glad I spotted it, that woulda been a very annoying one to debug later :) 18:33

timotimo at least this tells me my patch towards the optimizer to get lexicalref to localref lowering back in isn't breaking that particular thing 18:41

YuviPanda hello 21:26
if I've an open socket
how do I find the port on the client side the socket is using?
hoelzro YuviPanda: hello! 21:29
YuviPanda heya!
hoelzro IIRC, $sock.local_address *should* work, but looks to be NYI
YuviPanda shared a car ride with sjn, who talked about perl6 almost the entire time. I've been a bit hooked since 21:30
ah, damn.
timotimo oh, yeah, the method "accept" of IO::Socket::INET only sets the internal PIO attribute to the received socket
but it doesn't do any introspection whatsoever to make sure attributes are set up correctly 21:31
YuviPanda oh well. I'll find other things to test the simple Identd client I'm building (just to play around the language)
also, how would I have found this out?
doc.perl6.org/type/IO::Socket::INET doesn't have any of this
hoelzro YuviPanda: I discovered it by opening the source, but that's LTA 21:32
timotimo i looked at the implementation of the socket, hold no a sec
hoelzro holds his no's
timotimo github.com/rakudo/rakudo/blob/nom/...ET.pm#L113
YuviPanda LTA?
hoelzro "Less Than Awesome"
timotimo method accept and the next two methods
YuviPanda ah, ok :)
ah, right. the empty bits
hoelzro there should probably be logic on connect() to set the local address too 21:33
YuviPanda so next time I'm curious I'll try to look at the source as well
hoelzro or rather, !initialize
src/core/* is pretty friendly
not to mention authoritative =)
YuviPanda right :)
dalek rl6-roast-data: fdb4574 | coke++ | / (2 files):
another glr run for today
timotimo "pretty friendly"? ... well, in some places 21:34
it does contain a bunch of low-level operations (the ones with nqp:: in front)
and many times choices were made for performance reasons
hoelzro timotimo: ok, fair enough; as long as you don't have too many NQP ops
timotimo hah
hoelzro it's better than Perl6::Grammar, though =)
ShimmerFairy P6 and NQP code is generally easier to read than VM-level code, I find :)
timotimo and if you're operating very close to the beginning of the resulting core setting code, you'll have to be prepared for things just missing
YuviPanda fair enough, I guess 21:35
timotimo it's a surreal experience to try to define a subroutine near the beginning, but can't let it take a native int as parameter because the "int" type hasn't been defined yet 21:47
YuviPanda heh, that sounds fun :) 21:49
so when I'm setting up Actions for a Grammar
do they need to cover all the tokens / rules?
21:49 Gardner joined
timotimo nope, only those that exist will be called 21:49
21:49 mjgardner left
YuviPanda hmm, so how is the output ast formatted? 21:49
timotimo formatted? 21:50
YuviPanda aaah
so I need to call make
constructed, even. if I don't have one for TOP 21:51
(sorry, flaky connection)
timotimo right, "make" will attach whatever you give it to the $/'s .ast attribute
(alternatively accessible as .made)
if you don't call make for TOP's $/, it won't have a .ast/.made
but nested matches can still have an ast set on them that you can go dig up after the fact
YuviPanda right, that makes sense 21:52
ShimmerFairy YuviPanda: actions tend to construct larger "make"d things from what you can get from subrules. For example, if you have token Pair { <key> " kv " <value> } , then the resulting action method might be method Pair($/) { my $pair = $<key>.ast => $<value>.ast; make $pair } 21:54
YuviPanda right 21:57
ShimmerFairy: so paste.debian.net/304642/ is a fairly decent way to write that grammar and actions?
(first perl6 program I've ever written, be gentle... :))
would be nice to simplify the 'payload' action 21:58
timotimo you could "make $<error>.ast // $<answer>.ast i believe 21:59
YuviPanda what's the // operator? 22:00
timotimo defined-or
it'll give you the first defined argument, or if no argument is defined the last argument
ShimmerFairy YuviPanda: the only change I'd really recommend is ~$/<username> in method answer, if you meant to make a string 22:01
timotimo oh, yes

YuviPanda is $<X> a shortcut for $/<X>? 22:11
ShimmerFairy yes :)
22:12 amurf left
YuviPanda sweet :) 22:12
ShimmerFairy And $0 is a shortcut for $/[0] , for () captures 22:13
YuviPanda right
is it, uh, discouraged to use the shortcut vs teh more explicit $/<> version? 22:14
ShimmerFairy YuviPanda: that's why action methods almost always have $/ as their parameter, so you can use those shortcuts. If you picked a different name, like method my-token($a) , then it'd have to be a bunch of $a<subrule>s everywhere
YuviPanda: no, in fact it's more common to see people leave out the / for $<subrule> :)
YuviPanda Ah I see. 22:15
So both of those make sense now :)

YuviPanda ShimmerFairy: got it to paste.debian.net/304646/ which seems good except for not splitting out the parsing into a testable separate method, I guess 22:51
22:52 llfourn joined
ShimmerFairy YuviPanda: if you mean testing separate pieces of the grammar, you can leave out the :actions adverb (which just means .ast/.made won't do anything useful), and the :rule("request") adverb (or :rule<request> for short) would let you parse the string using the "request" rule, for example. 22:53
22:57 llfourn left
ShimmerFairy I should clarify, using .ast/.made on the result of Grammar.parse() won't return anything useful if you have no :actions or anything else that can 'make' in whatever :rule you use (which is by default TOP if you have no :rule in the parse call) 22:58
YuviPanda right 23:00
what do you mean by 'parse the string using the request rule'
23:01 amurf joined
ShimmerFairy YuviPanda: MyGrammar.parse("some string", :rule<request>) would let you parse "some string" starting with the 'request' rule, instead of the 'TOP' rule by default. Useful for testing parts of your grammar, for example. 23:01
23:02 RabidGravy left
ShimmerFairy m: grammar G { token TOP { <subrule> "---" <subrule> }; token subrule { \d+ \. \d+ } }; say G.parse("1.2---2.3"); say G.parse("0.6", :rule<subrule>); 23:03

YuviPanda aaaah 23:04
I see what you mean
right
so that'll let me test individual parts of the grammar
nice!
I was more mentioning that the query method does both the Socket stuff and the parsing, making it hard to test just the parsing with a unit test
ShimmerFairy Yeah, I figured after a bit. That could be remedied by having a socket-using method that returns the string, and then a method that handles the parsing of a string, though I'm not sure if you'd want the bare string to returned to the user 23:06
(but then again, there's always the possibility of a third method that neatly handles using those first two for the user ☺)
YuviPanda yup, a small internal method that just does the string, and a small internal method that just does the parsing 23:07
ShimmerFairy: so calling it 'my class ResponseParserActions' works, but not 'my class ResponseParser::Actions'
Could not find symbol '&Actions' in method query at Client.pm6:75 23:08
is what I get
which sounds fairly confusing
(perl6 hasn't been great so far in terms of error messages...)
ShimmerFairy the ::Actions version should work IIRC, that's weird
YuviPanda paste.debian.net/304656/
is the code with ::Actions
ShimmerFairy YuviPanda: the package-name error "Could not find symbol" is among one of the worse error messages, that's true :( 23:09
YuviPanda should I need to Nest the ::Actions inside the ResponseParser grammar?
ShimmerFairy let me check, I recall doing ::Actions and ::Grammar for stuff before without issue.

ShimmerFairy: can you report it for me? :) 23:18
ShimmerFairy and yeah, it seems to have no issues with a 'my class Name' and 'my class Name::Subname' inside a class, so it's some weird package handling screw-up :)
YuviPanda has got to go to sleep soon

ShimmerFairy ^ ok, managed to find a simpler example, now that I realized/remembered the D::E comes first bit :)
YuviPanda: Well, we ain't one of those mature compilers, so it's a bit easier to run into issues :) 23:21
YuviPanda yeah, I guess that'e ok / to be expected :)
I guess this is the first time I'm actually using and am excited by a still not mature language
ShimmerFairy And on the LTA error messages: I'm working on something for rakudo on the side, and while working on it I've had to make my own new Exception types, and I've realized that our error messages could stand to be a bit more verbose. Hopefully we can do something about that :) 23:22
YuviPanda nice :) 23:23
ShimmerFairy The "Cannot find symbol &Thing" message is because AFAIK rakudo isn't so good at figuring out what went wrong when it comes to package-related errors (i.e. whenever you start needing :: in names and something in the lookup process goes awry) 23:24
My only-slightly-educated guess is that rakudo doesn't quite realize yet that lots of people define namespaced things with Foo::Bar::Baz instead of package Foo { ... } , at least for error reporting :P 23:25

ShimmerFairy depends. If you have a specific pattern you want to find all the matches of, there's slurp("file.txt") ~~ m:g/pattern/ , which will put all the matches to the pattern in $/ 23:41
23:41 ggherdov joined
ShimmerFairy YuviPanda++ on your first rakudobug :) Here's the link to it rt.perl.org/Ticket/Display.html?id=125891 23:42
cbk1090 Ok I think I'll try slurp. Was really hoping to use a Grammar, for me it is easier to read and change the patter if I have to?
thanks ShimmerFairy
ShimmerFairy cbk1090: you can of course use a Grammar, but then you'd have to parse the whole file (IIRC there are methods that don't insist on parsing the whole thing, I think, but your grammar would still have to account for the uninteresting stuff) 23:44
YuviPanda ShimmerFairy: <3 thank you :)
cbk1090 ShimmerFairy, Yeah that was the problem I was having, the grammar really only works if there is a constant pattern to match. The files I'm working with are really just random text with some URLs 23:46
adu I merged some C::Parser stuff
ShimmerFairy YuviPanda: you're welcome. And I personally take it as a good sign of the compiler when the summary line for quickly describing the bug ends up being quite a bit long. Better than something like "Strings die on backslashes" :P
YuviPanda :D 23:47
is perl6 still on track for 'general release' by christmas?
ShimmerFairy cbk1090: you could always do something like token TOP { [<URL> | <!URL> .]+ } (that is, match either a URL or one character of a not-URL.) 23:48
23:48 adu left
cbk1090 But then how do I end up with a list of matching URLs? 23:49

ShimmerFairy cbk1090: ^ all the matched URLs will be available in $/<URL> after running the parse in this example 23:53
cbk1090 ShimmerFairy, ok I will try that method..... thanks 23:54
ugexe do actions happen *after* the grammar has been completely parsed? as in can you have actions that just emit to a supply, but also get emitted before the entire grammar is parsed? 23:55
ShimmerFairy ugexe: actions happen in a "bottom up" order, as opposed to grammars' "top down" order. So the most-nested subrule in a particular chain of calls has its action method called first. Basically, it's like putting a { } block that does the action method after all the regex stuff 23:57
ugexe would be cool if you could have a grammar emitting matches inside a react { }
ShimmerFairy ugexe: essentially, it's like regex foo { my regex stuff and then { the actions for this regex are at least somewhat equivalent to here } } 23:58
23:59 trnh left
ShimmerFairy ugexe: I'm not too clear on how the mechanism works specifically, but AFAIK you can think of actions as doing regex foo { stuff { ActionClass.foo($/) } } for you. :) 23:59
cbk1090 ShimmerFairy, ok I will try that method..... thanks
sorry bout' that
