grandtehftjiujit hello, I'd like to contribute to the perl6 docs on GitHub, however, when trying to build from the instructions I get an error when running htmlify.p6 02:01

grandtehftjiujit for the third build in a row I get "dot command failed! (did you isntall Graphviz?) 02:02
raydiak grandtehftjiujit: do you have graphviz installed on your system? it is used to render the type diagrams 02:05
grandtehftjiujit no, I was confused since the instructions hadn't mentioned it 02:06
that, of course, worked though :)
raydiak grandtehftjiujit: yeah I did the same thing the first time I contributed to the docs, and accidentally uploaded a version with no images :)
grandtehftjiujit I'm not sure how / if i'll be able to contribute... but I've been looking for a jumping in point 02:07
the right brew of things at the right time i suppose 02:08

grandtehftjiujit ic, that's quite alright 02:23
i'm finding it quite fun already. I felt like i was grinding my teeth a bit on perl5 so when I whipped my first rakudo spin I was pleasantly surprised / relieved / excited :) 02:25
raydiak glad to hear it :) I thought parts of it were a bit odd at first when I came from a p5 background, but I'm quite happy I switched now 02:29
TimToady isn't here either :) 02:33
yoleaux 19 Jun 2015 21:24Z <jnthn> TimToady: in STD, "my $exists = @foo[0]:exists" puts the adverb on the whole scope decl, because adverbs have item assignment precedence, put the initializer preclimits to item assignment. In Rakudo we wrongly had preclimit doing exclusive, not inclusive, checking, so we never noticed until now.
19 Jun 2015 21:26Z <jnthn> TimToady: s/put/but/. Also I don't immediately see a good fix; I suspect changing adverb's prec will have bad effects, but initializer doesn't feel like the right change either. Ideas welcome. :)

raydiak wonders if TimToady's quasiabsent state too closely resembles a ghost and scared grandtehftjiujit away 02:39
TimToady .tell jnthn well, it looks to me as though initializers are already correctly parsing at i= prec, so it seems like it would be pretty easy to give adverbs a precedence "slightly tighter" than that as it says in S03:1533, maybe "i^=" or so 02:43

TEttinger someone in another channel was describing the trouble he was having designing a compiler in Java. "It's just like, you want to start with no types, like ruby or something, and only once you understand it you assign the types." I smirked inside and said "like... gradual typing?" 07:02
07:04 ShimmerFairy left 07:06 RabidGravy joined
TEttinger so if I want to describe something in NQP that gets completely ignored after it's parsed, not even counting as a part of other parsed forms, how would I do that? 07:08
in clojure, the language feature that I want to implement is done with #_ followed immediately by the form to be ignored. something like (def myVar #_(/ 10 0) "the value I want") wouldn't ever evaluate the 10 divide by 0 07:09

I'm not sure here, how do I either make the existing ww method recognize more characters as valid components of names (that need spaces between tokens), or make my own equivalent to ww for a more permissive identifier char set?
if I just steal nqp's ww, it only uses word chars, but I allow more than taht 09:27
moritz TEttinger: you can implement the equivalent of ww with look-ahead and look-behind assertions 09:28
TEttinger I know in JVM regexes that uss something like (?>![my thing]) 09:30

(than other regex engines, since this isn't a regex, or is it?)
10:11 espadrine joined
jnthn Depends how you define "regex". token/rule turn off backtracking, which means you san performantly parse, but Perl 6 regexes are using the same syntax as the rule/token stuff you're using 10:13
m: my $b = 2; my $a = $b = 3; say $a; say $b; 10:16

jnthn .tell TimToady While that helps the colon pair case, we run into problems with pairs, as in "my $a = 'foo' => 'bar'", because those are %item_assignment too. Also chained assignments to declarators seem to go wrong (e.g. my $a = $b = 2).

when running as part of the spectest, t/spec/S17-supply/unique.t hangs for me

TEttinger I'm really sorry to keep bothering everyone, but... where would I learn more about how NQP grammar stuff works? I'm most of the way through Edument's NQP thing ( edumentab.github.io/rakudo-and-nqp-...s-day1.pdf ), even though it doesn't make that much sense yet because I'm still learning... Perl. 10:24
the Edument course didn't explain <!...> at all, so I am not thinking it will explain stuff like other regex-style matching 10:25
jnthn TEttinger: Did you read the Perl 6 regex/grammar docs yet?
TEttinger: 'cus the syntax is the same
TEttinger I have no idea where they are

TEttinger huh, lookahead is empty, it's just <?before foo> right? 10:29
jnthn TEttinger: Yes, <?before foo> or if you just have a char class <?[abc]>, or you can use any other token/rule as a lookahead with <?name>
And ! in all of those places instead for negative lookahead 10:30
TEttinger gotcha, thanks!
so if I wanted to check if there was this token, neither ahead or behind: token value:sym<variable> { ... } (there's a very long character class in there) 10:31
I would use <?!after variable> <?!before variable> 10:32
or would it need value:sym<variable>
jnthn Any time you see foo:sym<bar> it's part of an alternation (known as a "protoregex"
You can't talk about those directly
TEttinger ok, so put that in its own thing, have the protoregex reference it? 10:33
jnthn You should factor the shared stuff out to a token of its own, have your token value:sym<variable> look more like <variable>, and then use that.
Yes, you've got it.
lizmat takes a geezette nap 10:34
TEttinger oh, and <?!after variable> <?!before variable> will make it require Both of those, right?
similar to ww 10:35
jnthn TEttinger: ?! looks...odd
If you mean "not after a variable" and "not before a variable" just <!after <variable>> <!before <variable>> would do it 10:36
TEttinger doc.perl6.org/language/regexes#Look...assertions ?
huh
ok
jnthn Oddness 10:37
The ? is redundant, I thought...
TEttinger it also hasn't filled in lookahead in the section above
maybe outdated?
jnthn I suspect the lookahead bit is just "not written yet" 10:39

Get EXPR preclim fix; cope with its fallout.

The EXPR method used to incorrectly test against the precedence limit. This commit bumps to an NQP without this bug. This entails three small changes to Perl6::Grammar. First, we undo a hack in infix:<?? !!> that worked around the precedence limit bug, bringing us in line with STD. The second two changes are needed because we previously parsed both initializers and fatarrows as intended only due to the bug that is now fixed. STD gets things incorrect in these two cases also, but since it only does syntax, not semantics, it has never been noticed until now.
There is no spectest fallout with this patch. There may be a little ecosystem fallout, possibly because we were a little too liberal. With this change, RT #123623 is also fixed.
RabidGravy something like "class Foo { method bar is delegated { .. } } class Bar { has Foo $!foo is auto-proxy }" and an object of Bar has the bar method 10:58

Ven m: class A { has @.ints; submethod BUILD(:@.ints) {} }; my $one = A.new( ints => [1, 2] ); say $one.ints.elems 11:39
camelia rakudo-moar 9ed857: OUTPUT«2␤»
masak `my @foo = 1, 2; say A.new( ints => @foo ).ints.elems;` -- 1 or 2?
Ven two
masak agreed.
so `ints => [1, 2]` should also give 2
not a very solid argument, but maybe the beginning of a solid one 11:40
Ven I don't understand the argument. (1, 2) is (*currently*) different from [1,2]
masak basically, list assignment is not the same as attr initialization by constructor argument 11:41
Ven m: class A { has @.ints }; my $one = A.new( ints => (1, 2, (3, (4,))) ); say $one.ints.elems
camelia rakudo-moar 9ed857: OUTPUT«4␤»
masak if GLR makes that one into 3, I'm fine with that.
I'm talking specifically about [] DWIMming when passing constructor arguments. 11:42
I could probably dig up a very old RT ticket about this, too.
Ven m: class A { has @.ints; }; my $one = A.new( ints => $(1, 2) ); say $one.ints.elems
camelia rakudo-moar 9ed857: OUTPUT«2␤»
masak I remember discussing this in 2010 with mberends and jnthn, in the back of a car moving some of jnthn's stuff to .se
Ven (I don't have an opinion on that, FWIW. I can agree with both point of views) 11:43

Ven masak: what do you think of irclog.perlgeek.de/perl6/2015-06-20#i_10777713 ? 11:44
masak I'll also try to dig up the spec change that made things more in line with what I'm arguing for now.
Ven m: class A{}; role T[A]{}; T[5]; # <- doesn't fail 11:45
camelia ( no output )
Ven m: class A{}; role T[A]{}; T[5].perl.say; # <- but does here

masak Ven: I... think that's the first time I see a type capture inside a [] after a role in a type signature. 11:46
Ven: I agree it'd be lovely if that worked, but I'm not sure how realistict it is to expect it to work.
Ven: either way, please rakudobug it.
Ven I might've pasted another one like that before, not sure if that's been rakudobugged though
I think jnthn++'s answer was a bit of the same :-)
masak: well, I'm just wondering -- how could I write a polymorphic reverse? 11:47
timotimo jnthn: it could very well be that send-more-money-subs doesn't lower one of the sigs because the choose and guard subs take an &-sigiled variable and the lowerer doesn't check for that

oh, i was about to ask "what is this", but it's just %*
basically
masak vendethiel: thank you for pushing the limits of Perl 6 implementations the way you do. I find it very interesting. 12:19
timotimo we don't lower the signature of Capture.new, which is method new(:@list,:%hash) { 12:20
vendethiel masak: you must not consider yourself an "implementor" for thanking me *g* 12:21
(but really, thank everyone who did that in other languages / papers in literature / etc. I'm barely trying to translate it to p6)
masak vendethiel: I'm actually not sure whether I consider myself an implementor. but I see what you mean ;) 12:22
vendethiel: I am invested in Perl 6 converging on solid theory in cases like this. 12:23
12:24 AlexDaniel joined, Ven joined
Ven masak: I'm very scared by all the possible interactions. But perl6 is *consistent* at its core, or cheats really well to get there :) 12:24
masak walk & 12:25
timotimo aha! 12:26
it's quite possible that the slow-path binder gets invoked because Setty's submethod BUILD (does it even get called if it comes in from a role?) doesn't get lowered 12:27
submethod BUILD (:%!elems) { self }
TEttinger I'm trying to wrap my head around some of the rubyish code from the course. github.com/perl6/nqp/blob/master/e...#L694-L704 12:29
it assigns to $var , it puts it in the block[0] , but then later it does a make on a different variable 12:30
Ven also funny that this works:
m: my role X[::T] { my T $x; method f { say $x.perl } }; say X[Int].f; 12:31
camelia rakudo-moar 9ed857: OUTPUT«Int␤True␤»
TEttinger is the make really putting an identifier into the AST, not making a new Var ?
Ven but this doesn't:
m: my role X[::T] { method create(--> T) { T.new } }; say X[Int].create; say Int.new;

timotimo TEttinger: it looks like $block.symbol is also a setter, more or less 12:32
TEttinger: also, pushing something onto a block's first child is what you do to add lexical definitions properly 12:33
and the thing it makes is a reference to the created variable
TEttinger oh ok
timotimo you can see the difference in whether or not :decl is present
TEttinger so it's returning a reference regardless, but if it isn't declared already, it declares it first? 12:34
got it
timotimo sounds sensible to me 12:36

timotimo what engine?
jnthn: are you aware we seem to bail out of every method defined in a role because type_captures is set? at least it seems to be that way 13:03
um 13:05
or maybe that's the signature of the role itself? 13:06
jnthn Probably that of the role itself 13:08
[ptc] colomon: there's probably a lot of "quite", "indeed" and "rather" as well ;-)
jnthn I think we'd be seeing a lot more bails otherwise.
timotimo yes, you are right 13:09
Woodi timotimo: the thingie that moves corsor :) I assumed it's about grammars
timotimo Woodi: that's correct. where does "if(<?foo>) then { ... }" come from? that doesn't seem like anything in perl6
jnthn: what's tricky about doing method new(:@list,:%hash) { 13:10
Woodi no 'if's. just description how it could work...
timotimo it seems like it's a bail because we don't have a default value for @list
jnthn timotimo: Not sure without looking. Is it perhaps optional array/hash args?
timotimo yeah 13:11
i just put a ! at the end to see if the bail disappears :)

timotimo hm. i have no idea what nominal_generic does 13:15

hm. we quite often have ::?CLASS:D in signatures just because we want the :D, but don't necessarily know the class 13:18
that keeps the binder lowerer from lowering
bind_accessor being set in %info is never the reason for a bail 13:20

timotimo i thought it would be, but i'm not 100% sure how. just detecting it's ::?CLASS and as such we don't actually set the value of ::?CLASS
and also ::?CLASS: is never actually worth a type check
hm. actually ... not never 13:23
jnthn It can matter
timotimo like if we .^find_method for example
jnthn Well, it's more that we should emit code to look up the type var
(lexically)
timotimo fair enough
jnthn There's even a typevar scope iirc
So that spesh would know that it can cache the lookup if it's specializing on invocant type 13:24
Which means it could even eliminate the type check
timotimo i'm more worried about the reason why :%!config, for example, bails out because of "no default value, but we have a % sigil"
that means it doesn't properly set bind_accessor in the %info hash 13:25
oh, hold on
bind_accessor is for %.config
bind_attr is for ! twigils

yoleaux 17 Jun 2015 23:34Z <b2gills> dha: I sure hope you aren't trying to re-implement the Test::Builder module from Perl 5, which they are currently trying to replace with a better model
timotimo yeah, we have "pod6" now 18:32
dha In answer to that question, Test::Builder seems to have been implemented already. I'm working on Test-Simple stuff. But I'm probably going to take a break from that to expand heavily on the 5to6 translation docs. 18:33
timotimo - great! Where are those changes documented? 18:34
(see comment about writing docs above :-) 18:35
18:35 zacts left
dha It suddenly occurs to me that github will be made ill from p6 pod. :-/ Which I guess raises the question: would it be better to just write in p5 pod or plain text and convert to p6 pod later? 18:37
timotimo design.perl6.org has a document on it
18:38 zacts joined
dha How fixed is the information in that document? 18:39
18:40 lolisa left
timotimo relatively, i suppose 18:40
dha And, I guess for my purposes, is p6 pod a superset of p5 pod, or are there conflicts?
timotimo i don't know, i never did any perl5 18:41
dha Ah, so I guess what I'm working on is not really of use to you. :-) 18:42
timotimo pod5 to pod6 converter? :) 18:44
18:45 zakharyas joined 18:47 espadrine joined
dha I'm sure that would be handy. :-) 18:47
RabidGravy dha: at minimum your p5 pod needs a =begin pod .. =end pod round it and drop =over .. =back for lists 18:48
most of the rest will work
dha What do you use for lists in p6?
Just use =item ? 18:49
RabidGravy yeah
dha And does the requirement of =begin...=end hold for documents that are entirely pod?
RabidGravy yes (it is still parsed as perl 6) 18:50

Oh, that's you. Didn't recognize the new handle. ;-) 18:51

dha Ok, so I put a bunch of stuff in @array. then I go "say @array". It prints out the elements with spaces in between them. a) this is the behaviour of 'say "@array"' in p5, so does p6 say autoquote its arguments? Or is there some other thing going on here? b) Is it necessarily space separated, or is there a way of changing that, a la p5's $" var? 19:32

19:34 LonelyGM left
dha I should probably at some point figure out what that pipe character is doing. 19:34
masak this is one way in which (argument) lists and arrays differ.
dha: that pipe character flattens the array into the argument list.
dha: happens automatically in Perl 5 if you pass in a non-reference array. 19:35
dha Right. ok.
19:36 zakharyas left
dha I see the difference, but still not clear why the @array, rather than the argument list, gets the behaviour it does. 19:36
masak the proximal reason is that Array has a Str method which puts in the spaces. 19:37
dha So... basically... "Arrays just do that now." 19:38
masak m: my @array = 1, 2, 3; say @array.has("Str"); my $s = @array.Str; say $s
camelia rakudo-moar be122a: OUTPUT«Method 'has' not found for invocant of class 'Array'␤ in block <unit> at /tmp/s9NkyVZAY1:1␤␤»

camelia rakudo-moar be122a: OUTPUT«Str Str Str␤1 2 3␤»
masak m: my @array = 1, 2, 3; say ?@array.can("Str"); my $s = @array.Str; say $s
camelia rakudo-moar be122a: OUTPUT«True␤1 2 3␤»
masak dha: you'll have to ask TimToady for a deeper reason than that. 19:39
dha: but one difference between Perl 5 and Perl 6 is that arrays *don't* autoflatten. this at least forms the basis for the different behavior in the first place, if not a complete rationale. :)
dha So, if I'm understanding this right, @array's Str method is automatically invoked when it's used in a context that expects a string, and that stringifies it with the spaces? 19:40
masak aye. you are understanding this right.
dha The irony here is that I don't know why I'm trying so hard to understand this, since what I was really looking for was whether $" had a p6 equivalent... :-) 19:41
Oh good. I like understanding things right. :-)
masak hits S28 to look for a $" analog
yeah, S28 says there is none :/ 19:42
dha Does it say there will never be?
19:42 bin_005 joined
masak I'm not sure it has the authority to say that. :) but it doesn't look like there are plans for any. 19:42
dha For context, I've decided we need more info for people going from p5 to p6, so I'm starting that by going through all the special variables and pointing to what you would use instead in p6. 19:43
masak then S28 is definitely for you.
dha So, for $" the answer is "You're screwed."
masak the answer was literally "-" in S28.
dha How fixed is the information in S28? or any of those documents, for that matter? 19:44
masak it varies. S28 can sometimes get out-of-date with respect to more current documents.
(in this case I have no reason to believe it is, though)
dha ok. I guess I'll just have to live with that. Thanks for the pointer, though. 19:45
masak S02..S06 and S12 are "core" in some sense, and almost always the most current. 19:46
(and they thankfully don't change much these days)
RabidGravy dha, currently List.Str is literally: "multi method Str(List:D:) { self.join(' ') }" 19:47
dha Gesundheit. :-)
Actually, most of that makes sense. clearly I'm starting to ingest the Kool-Aid.
RabidGravy so if one cared one could augment Array with some different implementation or something 19:48
masak wishes the IT world hadn't landed on a metaphor which involves suicide cults :/

“Any decisive test or ordeal; from the former use of nitric acid to test a metal for its gold content.”
www.thefreedictionary.com/acid+test
masak oh! I stand corrected. 19:58

colomon “Acid test is American English, 1892, from the frontier days, when gold was distinguished from similar metals by application of nitric acid.” www.etymonline.com/index.php?term=acid
masak in other words, as most computer terminology, it comes out of California :P 19:59

Which also SEGV'd and is almost certainly the same thing
21:46 diego_k joined
masak ah, good idea. 21:46
RabidGravy I've concluded that rather than trying to guess whether SomeRandomType($some-value) will work is a mugs game, just trying it is best
21:47 diegok left
RabidGravy but a SEGV somewhat militates against that approach ;-) 21:47

RabidGravy jnthn, was it #125376 you meant? 22:00
jnthn yes but *sigh* 22:01
RabidGravy If so it's slightly different 22:02
jnthn Fixing a VM level SEGV by papering over it in Rakudo is just plain stupid.
RabidGravy I'll re-open and update
jnthn Thanks.
Will see if I can hunt it down tomorrow 22:03
masak should I revert the fix?
jnthn masak: The Rakudo patch may still be the best way to give a good message there. 22:04
masak ok, leaving it in.
22:04 burnersk joined
bartolin ha, I closed that one too early? 22:04
jnthn It's not that the patch is bad in itself, it's just sweeping a SEGV under the carpet is only asking for trouble later. 22:05
masak bartolin: no, it's fixed according to the letter of the law :)

jnthn *nod*
Please do try and make sure SEGV-ing things get fixed deeply. 22:06
22:06 espadrine left
jnthn I'm jumping on those I can. In the worst case, they can be exploitable security issues. 22:06
bartolin okay, I'll keep that in mind.
masak that is indeed worth remembering. 22:07
RabidGravy in my mind the VM should never segfault
jnthn RabidGravy: Mine too, which is why I want us to fix those places it does. 22:08
masak in my mind software should never behave not to spec. 22:09
RabidGravy looking at the BT of the Code(0), I think it may be completely different though
masak,aye but nobody every puts "must not segfault/must not GPF" in a spec, 'cause y'know .... 22:11
masak maybe they should. :> 22:12
'night, #perl6 22:13
japhb RabidGravy: People do put "must be warnings- and sanitizer-clean" in specs though.
o/ masak
bartolin o/
22:13 acsigusz left
RabidGravy true 22:14
also difficult to test 22:17
well a pain to test as you'd have to run each potential failure in a seaparate process and see how it exited 22:19
not sure you can even do that properly on windows
22:20 jack_rabbit joined 22:22 dha joined
RabidGravy mebbe a Test::NoSegfault would be useful to module developers though 22:28
jnthn wonders if a "SEGV report" on testers.perl6.org would be do-able easily 22:30
RabidGravy It reports the exit code of the tests, this could be munged to determine whether there was a segfault (on Unux-like operating systems anyway) 22:33
dha s28 indicates that $( and $) are replaced in p6 with $*GID and $*EGID, but the docs on Variables only shows $*GROUP which, I'm guessing, is the real GID? Does this mean p6 actually has no $EGID equivalent? 22:36
22:37 Al-Caveman left
RabidGravy not presently, $( is $*GROUP.Int IIRC 22:37
22:38 vytas joined
RabidGravy (that is I put those things in the Varaiables page but drank a lot of beer since ;-) 22:39
dha nope, Int isn't doing that, although since $*GROUP in numeric context is supposed to return the group number, I'm not sure why. $*GROUP.Str *does* return the group name.
RabidGravy let me look
dha $*GROUP.perl gives me IdFetch.new 22:40
RabidGravy ah $*GROUP.Numeric
dha Ugh. 22:41
And $EGID is currently not a thing?
[Coke]_ wishes irssi
nevermind. 22:42
22:42 [Coke]_ is now known as [Coke]
dha Well, I'm certainly glad you gave me that commit bit on the design docs. Looks like I'll be using it a bit... :-) 22:43
And, oddly, $( in Perl 5 is giving me a whole bunch of numbers. weird. 22:45
RabidGravy actually, IdFetch is probably odd, I think those things are broken and should be IdName objects 22:47
22:47 kurahaupo left 22:48 jercos_ is now known as JERCOS, JERCOS is now known as jercos
dha So... Obviously s28 should be amended with respect to $*GID/$*GROUP. Should I leave $*EGID alone there or indicate non-implementation? 22:48
RabidGravy I'd leave it for the time being. I don't believe the population of $*USER/$*GROUP is doing what it is intended to do 22:51
dha ok, I won't mess with s28 on user and group vars. FOR NOW. 22:52

RabidGravy will do patch in morning 23:06
dha Ok, moving on... $a and $b: no longer special at all, or does "Just params to anonymous block" (from s28) really mean something?
lizmat_ dha: there is no special meaning 23:07
