[Coke] samcv: looks like it's more than twice as slow here: gist.github.com/coke/1fb4a80aa8339...cc1a0a2981 02:23
yoleaux 00:18Z <japhb> [Coke]: IIRC there were two reasons for PNG versions of the type graphs: 1) Browsers that did not support SVG inline, and 2) Browsers with NoScript or similar security technology enabled (which often disables SVG).
[Coke] samcv: got a TON of duplicate messages during the final stages with the highlights version, not sure if that contributed. 02:24
samcv hmm
from travis's build it seems to be like 10% slower
but i'm working atm on being able to make it async
well the node side
and output json which contains the filename it read from and the html (newline delimited) 02:25
02:27 pyrimidine left
[Coke] samcv: note that parallel=2 SEGVS or worse with the current version. 02:28
(on master)
samcv yeah
[Coke] .tell japhb - yah, I'm suggesting that we have enough SVG support now we can drop that requirement. 02:30
yoleaux [Coke]: I'll pass your message to japhb.

samcv also i'm going to try calling stdout write directly instead of console.log 02:37
02:39 pyrimidine left
dalek c/highlights: 6180396 | samcv++ | highlights/highlight-filename-from-stdin.coffee:
Make highlights async, use process.stdout.write not console.log

console.log can do formatting of javascript data structures Hopefully will be faster printing that way.
Not sure if making it async will make it faster, the same, or slowing though.		 02:41
samcv well let's see what this does
really curious. 02:42
02:44 quicoju joined
[Coke] I can try again. 02:44

[Coke] v6.3.0 02:48
I see 6.9.2 is current, checking macports.
samcv that's probably fine i guess. i don't know much about node
i have v7.2.1 atm 02:49
[Coke] er, I guess current means something and I meant LTS.

[Coke] upgrades to 7.2.1 02:56
02:57 pyrimidine joined
samcv also i made it async so. it's maybe possible that now the wrong text will be in different places 02:58
but i think most likely not, since it waits for a response (perl6)
before sending the next request. so i'm 95% sure that won't happen
[Coke] died with Cannot receive a message on a closed channel 02:59
samcv at the end?
[Coke] your parallel isn't tied to --parallel?
samcv it doesn't do it parallel. i just made the node part asynchronous
idk coke maybe it sent a nonreal filename? though then i think it should print out an error 03:00
i'm building right now
03:02 noganex_ joined
samcv err or wait maybe i didn't make it async. hold on 03:02

dalek c/highlights: cbaca0a | samcv++ | / (2 files):
Actually make the coffeescript asynchronous

Also remove an unneeded repo from the Makefile.
  `highlights` is already in our node package file,
so it automatically downloads.		 03:14

06:20 xtreak joined
samcv why did you make class YTDL::App is Wx::App? 06:21
in perl 5 do you have to use base or you don't get the routine's imported? 06:22
06:23 cyphase left
holli the Perl5 code is right there. yes because it's supposed to ISA Wx::App 06:23
samcv i see the perl 5 code. but the question was just, if that sub is automatically exported or not
hold on i have Wx installed. let me see 06:24
holli i don't know
06:25 Tonik joined 06:26 bjz left 06:28 cyphase joined, raiph joined, bjz joined
raiph holli: what happened when you tried 'sub'? 06:29
yoleaux 19 Dec 2016 22:08Z <nine> raiph: your suggestion to use "method" instead of "sub" sounds entirely sane. Wonder if it helped.
raiph er, tried 'method'
samcv that doesn't work. i tried a sub
for me at least
06:30 bjz left, bjz_ joined 06:31 nige1 joined
holli neither "method" nor "sub" do work 06:32
06:32 bjz_ left
samcv i don't think you can inherit from perl 5 programs. you can use perl 5 objects and stuff though 06:34
and routines
inheriting from it seems like it wouldn't work...
nige1 .tell zoffix thanks for the tip to turn on JSON output for perl6 -> RAKUDO_EXCEPTION_HANDLER=JSON 06:35
yoleaux nige1: I'll pass your message to zoffix.
samcv but i could be wrong
nige1 .tell zoffix I've update the code to use JSON instead github.com/nige123/perl6fix/blob/m...r/perl6fix 06:36
yoleaux nige1: I'll pass your message to zoffix.
samcv oh holli 06:37
what you are looking for is not `is` but the `does` keyword
nige1 next time I'll show advent drafts to the channel first
samcv does inherits the way you want it to
class YTDL::App does Wx::App will inherit variables and all other stuff. does inherits mostly everything 06:38
but i get this error: Wx::App is not composable, so YTDL::App cannot compose it
idk somebody else here might know more about using Inline::Perl5 :\ 06:39
at least that's how objects inherit in perl 6, not sure about the magic that happens in inline
holli bummer 06:40
samcv well let me keep trying actually...
holli ponders writing a Perl6 to C wrapper for Wx 06:42
samcv have you ever used NativeCall before?
i've used it before, it's pretty good
holli nope. not a clue about c
samcv do you know C?
holli that's the adventure :)
samcv NativeCall is the perl 6 thingy that hooks up to NativeCall
err.
i mean hooks up to C libraries 06:43
holli i know. looks easy. emphasize on "looks"
samcv well i can help you a lot more with that than with inline perl 5 hah 06:44
i mean i'm not a pro, but i have used it some
raiph IP5 just uses NativeCall
samcv yeah
raiph you can create a P6 class that's a subclass of a P5 class
do we have a P6 bot that has IP5 and some P5 modules installed? 06:46

samcv that's pretty neat nine 07:32
how is that feat accomplished?
nine When you "use Wx::App" a wrapper class called Wx::App is created in Perl 6 which forwards method calls to Perl 5. You can inherit from this wrapper. 07:33
07:34 Tonik left
samcv can using Wx::App work though, because it tries to call a perl 5 sub? 07:34
nine Like in: niner.name/talks/Perl%205%20and%20P...-parser.pl

nine .tell holli I now understand the bug in Inline::Perl5 which causes your Wx app to fail. The subclass doesn't exist in Perl 5 and the Perl 5 constructor is called with "Wx::App" as package so $this->can( 'OnInit' ) will return the OnInit of the base class. Fixable but a bit involved. 08:29

ufobat is this a bad idea: token FilterExpr { <PrimaryExpr> | <FilterExpr> <Predicate> } because of the recursion in this token? and is this a bad idea esp because of backtracking?

labster Hi lizmat
lizmat also clickbaits p6weekly.wordpress.com/2016/12/19/...christmas/ 09:00
labster o/
labster Happy Advent
\o
ufobat DrForr, i am playing around with xpath 09:01
09:01 xtreak left
DrForr Oh, cool. I was just wondering because that expression just might allow more than you intended. 09:02
ufobat DrForr, i am trying to figure out why a) its so slow b) my grammar ony matches when i use Grammar::Debugger github.com/ufobat/p6-XML-XPath
i just wrote down the spec in a perl grammar, not much thinking about it first and just give it a try.. 09:03
09:04 BenGoldberg left
DrForr The first thing I see is that everything's written as a token. That's a bit odd to me, because tokens are usually single blocks of text. If you're in an XPath construct it's possible, but I'm not sure. 09:05
tadzik oh, someone did find that My Little Pony module, now I have to think of a prize :o 09:06
DrForr Sparkle glue? 09:07
arnsholt ufobat: It's a bad idea because it'll recurse infinitely if PrimaryExpr doesn't match 09:08
ufobat i tought so, so if there is recursion it must like token A { <B> | <C> <A> } 09:09
DrForr, what is the way to decide when a token is not sufficient? 09:11
jast only in a recursive descent / LL parser
DrForr Well, the thing is that's really just a way to generate arbitrary sequences of <B>|<C>, I *think*.
arnsholt Anyways, you can just expand it into FilterExpr { <PrimaryExpr> <Predicate>* } 09:12
DrForr And yea, BNF and LALR(n) aren't the same as PEGs.
arnsholt ufobat: More or less. You need to consume at least one more character before recursing back into A
jast that's a different expression, actually
arnsholt So it'd fail if <C> can match the empty string
ufobat AH! 09:13
DrForr arnsholt: I thought that was the case to, but <primary><Predicate><Primary> is allowed because of the recursion, and I didn't think he wanted that. That's why I was curious about the language.
ufobat: I generally follow the rule that a token is meant to be a single term like 123 or -23.7 or "foo bar", and anything else is a rule connecting tokens. 09:14
arnsholt A primary after the predicate isn't licenced by that FilterExpr rule
jast wouldn't it be: FilterExpr { <PrimaryExpr>* <Predicate> }
arnsholt jast: That's what I thought initially too 09:15
DrForr Oh, I ws reading backwards. My bad.
arnsholt But if you sketch the parse tree top-down, you'll see it
ufobat jast, probably, yeah :)
jast oh, yeah
arnsholt FE => FE Pred => FE Pred Pred => ...
jast man, reading grammars is hard :)
arnsholt Yeah, it's really hard to develop good intuitions about them
jast I actually think ordered choice instead of | makes it easier to understand them 09:16
not "easy", though
ufobat DrForr, but rules are "tokens with whitespaces" right? if so why is a rule "probably" better?
i thought my probelm is to identify when backtracking is required and when it isnt 09:17
jast because of the PEG-like capability's of P6 grammars you can often avoid left recursion a lot more easily than with traditional grammar definitions 09:18
dang, I did just put that apostroph there, didn't I? bad day, apparently...
09:18 thayne joined
arnsholt Where PEG-like is quantification of subrule matches? 09:18
DrForr It makes your intentions clearer, to start.
jast in this case, yeah 09:19
arnsholt That's easily expressible in both top-down and bottom-up CFG parsing though
jast it is, but with traditional definitions you have to split up your productions further, with this you can avoid that
arnsholt There's a PEG component in HLL::Grammar in NQP, but that's not directly available to Perl 6 grammars
jast (when using top-down parsing, at least. LR-type parsers don't care about left recursion, of course.) 09:20
09:20 ocbtec joined
DrForr BNF and other grammars go through hell to represent <X><Y>* and <X>+<Y> because of {reduce,shift}-reduce conflicts; PEGs don't have that problem. 09:20
jast neither do the other bottom-up techniques I can think of 09:21
ufobat let me refere to one of my first questions again. the speed issue. Grammar::Debugger tells me that i am not using the mentioned token, still the .parse() is much! slower with that token in it. is that "okay" or a bug?
arnsholt The thing some bottom-up algorithms doesn't like is empty productions
jast without knowing anything about the internals, I'd say it's something that could probably be improved on :)
ufobat having all my "wrong" tokens in my grammar without Grammar::Debugger it doesn't parse at all, but with G::D it does
arnsholt But the details of that escape me. It's been ages since I learned about that stuff 09:22
DrForr I'd say it was Grammar::Debugger interfering with your grammar. It modifies the grammar internally to inject debugging code, but that can change the grammar itself as well.
jast I don't know about all of the details either
arnsholt And I haven't had occasion to use them since, these alagorithms being pretty useless for natural languague =)
jast do you do other kinds of NLP, then? 09:23
I mean there are algorithms that can deal with ambiguities in a grammar... not that that makes your statement any less true :} 09:24
ufobat are there other ways of debugging a grammar without modifing it.. maybe an action class with a good sub FALLBACK?
arnsholt jast: I didn't do much parsing (recently left academia and became a developer =), but yeah for grammar-driven parsing you'd use other algorithms 09:25
DrForr ufobat: FWIW I've seen several cases of G::D interfering with existing grammars just as you're describing. I didn't hae the knowledge at the time to try to debug the problem so I stopped using the module and relied on a better test suite.
arnsholt Most notably CKY
jast I haven't done a lot of exotic parsing myself, but for a while I had these crazy ideas about creating a language with syntax that is fully mutable at runtime... 09:26
so I read a lot of papers about... things.
09:26 wamba left
jast ufobat: if all else fails, you could try and involve a few extra pairs of eyes 09:27
DrForr jast: I have a module that does that on a drive somewhere, though it never got around to being completed.
arnsholt jast: "syntax ... fully mutable at runtime" Perl 6 you mean? =D 09:28
jast for extra difficulty my ideas involved static typing
with optional type inference
and I don't really have the patience to actually sit down and implement that with all of the crazy implications, when there are "close enough" languages that already exist 09:29
DrForr ufobat: I understand the idea of just doing black-box testing, but I think you'd be happier with a larger test suite probing just the .parse method - you can add a dynamic variable to dump the test output without having to test the entire find* layer.
jast one example being Perl 6, yes
ufobat okay :-) thanks for all the help and ideas, i am trying to avoid the left recursion first 09:30
DrForr jast: Apple Dylan tried something like that a *long* time ago, albeit not to much success.
lizmat news.ycombinator.com/item?id=13216924 # correction: tadzik's advent post
ufobat DrForr, absolutly! 09:31
jast I gave up on the idea of "fully" mutable after a while, anyway, because if syntax can be freely mutated by any module you use, you can run into nasty conflicts very quickly 09:32
ufobat is there a Test::* module that provides timeouts for methods? because its not fun testing something that goes into a infinite recusion till everything blowes up 09:33
DrForr ufobat: Also, check out github.com/drforr/perl6-ANTLR4/blo...t/03-ast.t for some other ideas. I need to finish rewriting it due to the fact that the code predates the GLR, so please don't take the general case seriously.
ufobat ty!
DrForr ufobat: Oo, good idea. I'm not aware of one, though usually when I'm dealing with a spin-lock like that it's inside the actual parser and not a set of mutually-recursing terms. 09:34
09:35 rindolf joined
DrForr ufobat: Also the grammar itself may be of interest, as it's parsing an XML-like grammar then *generating* a Perl6-like grammar :) 09:36

marchelzo notviki: why?
i have an even shorter name that would be better 13:42
in-Z
notviki marchelzo: because you'd know we don't have methods for checking whether something is an int so assuming .is-int is a method on a Mu or Any for checking whether something is an Int object (or is it the native int?)
mscha marchelzo: .ℤ 13:43
13:44 pyrimidine left
marchelzo ok, but still, it reads as though you're asking whether the Range is an int. 13:44

DrForr mr_ron: Yes, 1 and I can be hard to distinguish, and there are a bunch of different X-looking characters in Unicode. I'm not sure what you're asking or suggesting though.
marchelzo notviki: exactly. so why are you doing it?
having is-int on string that checked /\d+/ would make sense for example, because then the string would literally represent a valid integer. but a range is never an integer. unless maybe the endpoints are both the /same/ integer. 13:46
notviki marchelzo: so you could come here every December and argue about our method names, of course. 13:47
marchelzo ?
notviki I see in 2015 you were arguing about .roll on a Bag being a poor name.
marchelzo haha really?
i don't remember that 13:48
why doesn't perl6 allow ? in method names? allowing - seems like it would pose even more challenges for the parser 13:50
awwaiid '-' has some limited placement rules that help, but it is hard on the parser for sure
mr_ron DrForr: the example tries to show code that looks very similar but gives different numerical results. It seems that nobody is very concerned though. Don't quite understand the use case for Unicode Nl numerals when you have a module that does that. 13:51
I guess it looks neat ...

moritz marchelzo: but the question could be extend to any number of characters, and the answer is that you get more corner cases the more characters you allow
marchelzo: and - seems to be pretty common as a word separator 13:53
marchelzo ? would save you from the is- prefix
notviki marchelzo: we have .? safe-call operator
jnthn Would also be formally ambiguous with .?foo
awwaiid marchelzo: a prefix '?' does bool coercerion. Yeah, in rubyland they love the '?' ending on method names to eliminate the is- prefixes
moritz and if you try to read the code, your voice goes up to formulate a question after reading the method name, even if the sentence isn't finished
mst awwaiid: I kinda like it from lisps 13:54
awwaiid marchelzo: many of these broad language questions can be summarized as: it was certainly considered and this is what we ended up with so far 13:55

DrForr "it" being the change between $a and @a? I think you've got the wrong end of the stick here. @a and $a is the important bit here, the RHS can have the same text no matter what the LHS is.

marchelzo right but apart from the names
[Coke] DrForr: well, they're more the same than they are in p5. :)
marchelzo the fact that it was declared with @ doesn't change its behavior

DrForr One assigns to an array, the other assigns to an array *reference*. 14:42

marchelzo yes
DrForr $a is still [1,2,3] in the example, it doesn't turn into [[1,2,3],]. The [..,] is added because $a is one of the arguments in the list. 14:47

marchelzo samcv: which one didn't work?
23:06 dataf3l left
samcv m: 'abc'.trans('a' => 'zzz').say 23:06
camelia rakudo-moar b8df3a: OUTPUT«zbc␤»
AlexDaniel right, because a pair works differently
m: 'abc'.trans('aby' => 'zzz').say
camelia rakudo-moar b8df3a: OUTPUT«zzc␤»
MasterDuke the docs show examples docs.perl6.org/routine/trans
AlexDaniel MasterDuke++
samcv don't confuse me with the facts MasterDuke
;)
MasterDuke but the docs for trans could use some more explaining 23:07
samcv ^
AlexDaniel MasterDuke: file an issue
samcv also uhm i guess we could just use trans to do every single control character?
AlexDaniel samcv: yes! That's what I was saying :)
MasterDuke samcv: i made the exact same error the first time i tried to use trans
marchelzo write the json parser in C

AlexDaniel .tell jnthn ｢$proc.start(scheduler => ThreadPoolScheduler.new);｣ seems to work. What's going to happen if I create a new scheduler for every Proc::Async (just like in the example)? 23:17
yoleaux AlexDaniel: I'll pass your message to jnthn.

samcv i'm working on getting the docs with highlights things being possible from multiple threads using json. just have to get the perl 6 part to work 23:32
though i think it crashes if using multiple threads far before it gets to the highlighting part 23:33

samcv nice it works now :) 23:36

dalek c/highlights: 7ab0b2a | samcv++ | / (4 files):
Use a new CSS file name so we don't have to deal with caching

Also is renamed to be accurate about which highlighter it is designed for.		 23:41
c/highlights: 58770cc | samcv++ | h (2 files):
Use JSON to communicate with highlights

This will allow us to use multiple threads by waiting for the results from the correct file to be returned, and not just using the result returned most recently.

notviki dudz: it's author rarelly visits here. You may wish to tweet him instead: twitter.com/briandfoy 23:57
AlexDaniel Hm, I wonder what people think about reversing the arrow direction in our type graphs. If it's not UML anyway, why make it point to the parent?
dudz arh yes
a tweet isn't a pm right, its a public message? 23:59
