AlexDaniel hm, what's the easiest way to split a range into several subranges? 00:08
00:08 cdg left
samcv rotor 00:08
you trying to thread it?
AlexDaniel yup
[Coke] any feedback on the levenstein search? 00:09
*levenshtein
babydrop [Coke]: some searches return a ton of results... will that levenshtein exacerbate the issue?
AlexDaniel [Coke]: how fast is it? What about using Sift4? 00:10
samcv m: my $words = any(<PENGUIN>); (0..0x20000).».uniname.contains($words).say; say now - INIT now
camelia rakudo-moar 0c75e5: OUTPUT«any(True)␤0.58537436␤»
samcv that's fast

camelia rakudo-moar 0c75e5: OUTPUT«any(False)␤0.59398663␤»
samcv :) 00:11
half a second isn't bad
[Coke] AlexDaniel: fast enough? don't know what sift4 is.
babydrop samcv: that looks wrong.
AlexDaniel [Coke]: siderite.blogspot.com/2014/11/supe...tance.html
samcv is it
babydrop OK :)
samcv it could be. but it returns true for real words and false for words not in it

timotimo sounds like it'd stringify the names of all those characters into a single string
babydrop samcv: you're calling .contains on one huge string
AlexDaniel [Coke]: it's like levenshtein but much faster
samcv yes 00:12
babydrop
.oO( premature optimization... )
AlexDaniel [Coke]: for example, we're using in on whateverables (even though we didn't need any speed boost)
it*
samcv well that's the theoretical maximum speed it can go babydrop
doing contains on one string
timotimo i see no post on the advent calendar blog yet; they're supposed to go up around this time, right? 00:13
BenGoldberg m: my @props; my @words = any <GUN LAGAR>; my $results = (^0x20000).grep: { (@props ?? .uniprop.contains(@props.any) !! True) and (@words ?? .uniname.contains(@words.any) !! True) }; say +$results; say now - INIT now;

BenGoldberg Would anything break if any(Seq) did not unlazy the contents of the Seq? 00:18

it creates a hash of all of them

AlexDaniel samcv: how can it be so much faster, I don't get it :o 00:56
samcv hmm 00:57
it is awesome tho
but interesting how much faster it is
but uniname is really fast tho
it goes straight through almost to moarvm 00:58
AlexDaniel samcv: about 9 times
than the current version of unicodable
samcv yeah
i mean it's really fast, i mean even uniprop which is a lil slower
takes 8 seconds on my laptop to go through all unicode symbols 10 times
so 10 times 0x1FFFF 00:59
it's always been the .contains part and calling it so many times, but. i think
it's because no junctions
^ 01:00
babydrop SmokeMachine: wanna fix that bug?
samcv at least a big part
babydrop SmokeMachine: it fails in this check: github.com/rakudo/rakudo/blob/nom/.../Int.pm#L6

TimToady * doesn't go past 'or' 01:08
babydrop Thanks.
SmokeMachine babydrop: should I create any test?
AlexDaniel samcv: interesting. You can probably automate a lot of it
samcv this 'perl6 implementation' would have to be recompiled for every new roast, but
babydrop SmokeMachine: of course! That's the only way you know the fix works :)
AlexDaniel samcv: I wonder if it would be able to run any user code
samcv doubtful
unless like
you typed exactly the same thing as roast tested 01:09
AlexDaniel depends on the values you use :D
samcv because all values are hardcoded
yeah
SmokeMachine babydrop: Where? (Im sorry about so many questions... but thats my first time... :))
samcv oh in roast SmokeMachine 01:10
babydrop SmokeMachine: it's cool
01:10 kyclark left
samcv in S32-num/int.t i think 01:10
SmokeMachine samcv: roast is a different repo, isn't it? How should I do that?
babydrop SmokeMachine: the test goes into github.com/perl6/roast The way I do it is `tree -f | grep -i` some term.. In this case I'd use `tree -f | grep -i uint` which gives S02-types/int-uint.t 01:11
SmokeMachine: fork it, and in your rakudo repo, do git clone URL-TO-THE-FORK t/spec
And to run it do make spectest
SmokeMachine ok! doing that! 01:12
babydrop And to run individual file run make t/spec/S02-types/int-uint.t after you add your test
samcv babydrop, that info should be in the README
tbqh
babydrop samcv: I think it is. But I also plan to make contribute.perl6.org a web app that has all this info in an interactive way sortof
github.com/perl6/contribute/blob/m.../DESIGN.md 01:13
samcv it's not in there babydrop
somebody who knows more about roast than i do should add it, since i just ran the tests individually before :P

samcv the Bag part makes it slow
babydrop SmokeMachine: build it. And then in rakudo's repository run `make t/spec/the-file-you-added-the-test-to.t` and it'll run it 01:25
And also run `make spectest` to ensure the fix doesn't break anything
SmokeMachine babydrop: should I follow the REDME?
AlexDaniel samcv: well, that's not how it should be used, I guess :)

babydrop that looks like a problem that wishes to be resolved before release :o 01:39
If only I knew how :(
samcv ok i can make uniprop 4.5 times faster when not specifying any terms 01:40
idk if that's useful idk
but 4.5 is a big number. the signature would change though. 01:41
multi sub uniprop(Int:D $code) { } and multi sub uniprop(Int:D $code, Stringy:D $propname) {}, instead of having only one which is multi sub uniprop(Int:D $code, Stringy:D $propname = "General_Category") {}

babydrop SmokeMachine: yes, that's where the code should go, but since you're doing it off your fork, make a branch (git checkout -b whatever-you-want). This way the PR would be in a branch and you're still free to use the nom to make more PRs by doing the same branch-per-fix thing

arnsholt The Rakudo code can be scarier, but generally not too bad either
samcv nqp has been easier as i've seen it used and stuff. and it can be very practical to make things faster as i saw in my uniprop changes 09:19
nqp repo better to learn from than rakudo for that reason? less complexity? (i.e. optimizing a complex action so the code looks all over the place)
arnsholt NQP is easier to follow because NQP is a simpler language, basically 09:20
So less complexity, I guess
timotimo you can make code faster in rakudo by using nqp:: stuff mostly because our static optimizer and code-gen are far from perfect ;( 09:21
arnsholt Yeah, optimization is hard
(Solving halting-equivalent problems in O(1) time, as jnthn++ once put it to me)
timotimo worst is that those optimizations all sound so easy 09:22
... then you sit down in front of the code and realize the true horror of what you were hoping to do
arnsholt Yeah, it sounds so obviously straightforward to optimize code
And yet it's so hopelessly complicated
At that point, it's useful to keep Rice's theorem in mind 09:23
timotimo damn, that's harsh
(just read the TL;DR of it)
arnsholt Yeah, it's basically the generalized halting problem theorem 09:24
timotimo samcv: i expect you've also already seen the ops.markdown doc in the nqp repository? github.com/perl6/nqp/blob/master/d...s.markdown 09:25
arnsholt For any non-trivial property P, it's impossible to write a program that identifies programs with the property P
samcv yeah that is good reference :)
arnsholt Where a trivial property is one that either all or no programs have
samcv also been grepping all the source code a lot which is very useful
and reading all the places something is used etc
timotimo mhm 09:26
there's also an important difference between using nqp::blah in rakudo and using the nqp compiler itself
arnsholt timotimo: decont all the things, you mean? O:) 09:27
timotimo decont is one thing, hllize is the other thing
arnsholt (And := all the things)
timotimo nqp itself doesn't have scalar containers
and types in nqp-land don't derive from Any
and you get hllize calls generated for values crossing nqp-rakudo-borders 09:28
maybe it's not as important as i thought before i started formulating ... 09:29
samcv rakudo never returns a non object though right 09:30
but it's as i expected if using nqp in rakudo it's fastest to keep sections of the code in one or the other and not go back and forth, well unless performance differences are big
the static code analyzer is in Moar right 09:31
09:31 AlexDaniel left 09:32 dakkar joined
timotimo no, that's the dynamic one 09:32
psch the static one reshuffles QAST, doesn't it
timotimo the static optimizer lives in src/Perl6/Optimizer.nqp
correct
samcv ah ok 09:33
timotimo to get a feel for the static optimizer, compare --target=ast with --target=optimize in rakudo (or in nqp; it has its own optimizer) 09:34
to get a feel for the dynamic optimizer, put a path/filename in MVM_SPESH_LOG and look at the "before" part of "inserting logging information" vs the "finished specialization" blocks for the same frame

a solid understanding of Angular 1.x's concept of scope requires a decent understanding of JavaScript's concept of object prototypes. 12:45
cf. "isolated scope" 12:46
pmurias I like squeezing my thought patterns into the very specific way angular forces you to structure your app
masak I like structure, too.
but React (for example) can give you structure without overwhelming you with odd edge-cases and a zoo of weird CS-esque terminology 12:47

If I wanted to create a dynamic grammar, how would I go about doing that? Are there examples on the web of this? 16:18
SmokeMachine ugexe: mine isn't done yet... I'm sorry...
Xliff Primarily, I would like to keep a pattern in a scalar, and then have the grammar use that scalar in a regex.

psch oh, right, we have those too

i mean, a bunch of dynvars wouldn't be the greatest interface for a module 16:44

timotimo oh, about how some names are ambiguous? 20:56
samcv well they're not ambiguous they're the canonical unicode defined names 20:57
well anything but the names are ambiguous basically. and uppercase and lower case are different. like Sc vs sc, one's a property one's a General Property value 20:58
because reasons
i think the moarvm script to generate the datastructure must create lower/uppercase/shortened versions itself because i found them nowhere in the unicode files
err i guess ambiguous to moarvm? i think it has different values for the same things like 'sc' points to the wrong thing. like two thinks called 'sc' with different values in the data structure 21:00

samcv i think i'll just make an extra multi for when somebody supplies a unicode property to check against
there won't be an issue if you don't specify which property to check, so i think calling 'uniprop' and checking that, will make sure i don't have to duplicate the code i wrote to fix uniprop 21:13

Another odd error message from rakudo. 21:16
samcv substring length cannot be negative... hmm 21:18
does it tell you a line?
Xliff Nope
I swear, I have so many things in the oven where rakudo DOES NOT give me a line but a cryptic error message. 21:19
Like 6 stalled projects.
And I can't golf most of them down to the gristle.
A couple of 'em are dying of old age in RT 21:20
AlexDaniel timotimo: what kind of extra draughts do you want?
samcv Xliff, just start commenting out lines until the error goes away :P
Xliff samcv: It's not the where... it's the why. 21:21
samcv it's addunit that's doing it i think 21:22
Xliff Of course, I knew going in that anything I wrote with the MOP would be shaky. I don't quite think I have grokked all of its implications.
Yes.
$g.^add_method("unit:sym<$unit>", token { <sym> });
samcv #$g.^add_method("unit:sym<$unit>", token { <sym> }); h
yeh
Xliff I can do "$g.^add_method("unit:sym<ft>", token { <sym> });" and get the same thing. 21:23
If I do "$g.^add_method("unit:sym<ft>", method { <sym> });", it works but I don't see the method in the resulting composed class.

phatbot Xliff: what are the tickets? Except the scary XML one.... what are the other 6 stalled things? 21:45
Xliff LOL! The scary XML one is the one I really want.
But I understand why everyone cringes in fear. 21:46
3 of them I have not RT'd because of the lack of response on the XML one. I can't get the problem golf'd down, so I don't want to go through all that again.
[Coke] Xliff: we can't fix the tickets we don't have. 21:47
regarding this one, I'm not sure that add_method is tested anywhere to work with grammar methods. (how do you know if it's a token or a rule?)
Xliff [Coke]: That's what I thought.
[Coke]: with respect to RT. I've learned that it's better to crunch things down to a use case before submitting. 21:48
phatbot Xliff, well, no wonder those projects are stalled :)
Xliff Yes.
phatbot Are all of them as scary as XML one?
[Coke] Xliff: sure, it's better, but not ticket is worse, no?
Xliff Well that and I think that there is coder error in those. I'm not sure that rakudo is at fault... yet
[Coke] *no
Xliff phatbot: Most, yes. Hence my trepidation.

SmokeMachine how are you highlitining your code on wordpress' advent calendar?

SmokeMachine I was trying to use the vim's :source $VIMRUNTIME/syntax/html.vim... but I don't know why its not working... 21:53
moritz Xliff: fwiw I've just noticed that there's an add_multi_method as well 21:55
instead of just add_method
SmokeMachine I got it!!! its 2html.vim!!!
Xliff moritz: I was about to ask, how to add a method into a grammar so it acts like a rule.
moritz Xliff: a regex/token/rule is just a method, so that's not really the question 21:56
Xliff "token", "regex" and "rule" are just methods with syntactical sugar, right?
jinx
moritz Xliff: the real question is: how do you add a multi to an existing token?
Xliff Oooo
moritz and does that need to be different for grammars
Xliff Uncharted territory, here?
moritz for me at least
Xliff :) 21:57
moritz codegen was never my forte
Xliff Are token:rule<sym> rules multis?
I would guess so.
moritz would guess so too
Xliff Just never looked at them that way because it never occured to me to do so. 21:58
Well, I can try to see if it gives different results.
moritz Xliff: success! 21:59
Xliff moritz: ? 22:00
moritz Xliff: perlpunks.de/paste/show/584f1dec.5578.5c
Xliff: one problem was that you did $.parser.HOW.^add_method
it's just $.parser.^add_method or add_multi_method
Xliff Ah.
moritz++! 22:01
moritz so you added the method to the metaclass, not to the class :-)
Xliff LOL
22:01 skids left
moritz the set_name call isn't necessary 22:01
(and you don't have provisions in the grammar for skipping <mag>, so your first example could never match)
Xliff \o/ 22:02
Thanks so much!
moritz you're welcome
moritz blames jnthn++ for making meta programming look so easy in his talks, when in fact it's often hard, and most of all hard to debug 22:03
Xliff No kidding. 22:04
Now here's another problem. If I make <mag> optional, it will chew into the unit.
Since "f" is a valid <mag>, "ft/s" -> <mag> = "f" and the rest fails since there is no "t"
phatbot SmokeMachine: it's this gist.github.com/zoffixznet/356a944...ecb233a308
Xliff How can I force <unit> to match before <mag> 22:05
Is this look ahead sort of territory?
phatbot SmokeMachine: we actually have modules.perl6.org/dist/Pastebin::Gist in ecosystem, so it'd be trivial to make it roundtrip a Markdown file to html
samcv my REPL is broken now :(

jnthn The array subscripter decides whether to auto-viv for not based on .is-lazy

jnthn YOu can say @a[2..*]
And it'll truncate
phatbot AlexDaniel: $x x $y ?
AlexDaniel no, associated with subscripts
jnthn It's usually a DWIM and you've got eager/lazy as an escape hatch 22:21
phatbot m: my @a; @a[lazy 3..5] = 1 xx *; say @a

phatbot So how come /<sym>/ bug wasn't reported? Was it ruled DIHWIDT? 23:20

loveperl How to make comment blocks? 23:22
timotimo #`( ... ) will do it 23:23
or any kind of matching parenthesis
phatbot Or press the "Comment" key in your text editor :)
loveperl in vim
?
phatbot I've no idea what it is in vim, but it gotta have one 23:24
Ctrl+D?
That's what I have, but I'm pretty sure I always remap it to that combination
(in Atom)
timotimo in vim you typically have a cool plugin to do commenting for you, like NERDCommenter

Xliff phatbot: Understood. 23:33
Thanks for looking at them. 23:34
phatbot: Atom uses Ctrl+/ by default, I think
MasterDuke Xliff: i also tried replicating your XML one, but couldn't. it seemed like whatever module you were using (LibXML?), you had made some changes to it and i didn' 23:37
't have them when i just downloaded it from the ecosystem

maxp_ good evening... 23:40
is there a way to debug regular expressions?
23:40 kyclark left
timotimo yup, install Debugger::UI::CommandLine and use perl6-debug-m on your thing 23:41
it'll single-step through your matching process for you
maxp_ ok thanks
timotimo if that doessn't work or it's not the right thing for you, try Grammar::Debugger from the ecosystem, which also comes with Grammar::Trace
maxp_ but Grammar::Debugger is for simple regex too?
timotimo yes 23:42
timotimo goes AFK
maxp_ ok thanks a lot

Xliff MasterDuke: You should use the git repository. I think I included it in the bug. If not, I will update. 23:46
And you shouldn't need the XML:: parts at all to get the error to occur.
23:46 girafe left
Xliff I will have to take a long look at that bug and see if I can golf the problem down. There is a lot of code to go through, though. 23:47
And I am wondering if that is part of the problem.
It would explain why my efforts to golf it have failed.
MasterDuke i tried to follow the directions in the bug report, but something didn't work
Xliff Which bug was this again?

23:49 mawkish_ joined
Xliff OK. Let me see if I can come up with better instructions. 23:49
MasterDuke hmm, i guess if i had commented out all the XML::LibXML stuff it wouldn't have mattered that maybe our versions of XML::LibXML are/were different. but i think the code wouldn't run for some other reason 23:51
23:51 loveperl left
MasterDuke i.e., it wouldn't compile, so i didn't get the MAST frame error 23:52
Xliff OK. You need XML::LibXML from here: github.com/Xliff/p6-XML-LibXML.git 23:54
In 01-basic.t in the p6-xslt dir, comment out "use XML::LibXML::CStructs :types;"
That should get the error.
Make sure your -I points to the lib dir of both XML::LibXML and XML::XSLT you have cloned. 23:55
I wish I could make this simpler. *sigh*
MasterDuke Class CStruct has no attributes, which is illegal with the CStruct representation. 23:58
