timotimo i'm not to blame in that case :3 00:22

i want to report it but i feel like i need something a little more specific than a project a few hundred lines long that takes 3 minutes just to get to the segfault 00:23
timotimo golfing is a high art :( 00:24

at this point i'd be thrilled to fall for one who hates me, the whole 'just friends' thing is getting kinda boring
and any pointers on golfing? i actually keep bumping into things that i try to pinpoint the problem in, but can't. memory leaks in moar, segfaults in parrot, etc etc 00:33

ren1us actually, someone tell me i'm not crazy: for %.hash.keys { # stuff # }; <--- once this loop completes an iteration, assuming no variables outside the loop are changed, all objects defined inside the loop should be garbage collected, right? 00:45
gtodd "completes an iteration" or "completes" ... 00:50
ren1us completes an iteration 00:51
so if i did something like for 0..9 { my $a = A.new; doSomething(); }; where doSomething defines a gazillion objects and such, it's not going to wait until the entire loop is finished before garbage collecting $a and everything created by doSomething() 00:54

02:18 noganex left
Mouq lue: github.com/Mouq/pod-walker/commit/...4b06f4b112 02:18
lue: I wouldn't be surprised if that's the completely wrong approach 02:20
lue: But I'm close to having a copy of Pod::To::HTML that runs locally with that, even if incorrectly in many places
s/runs/compiles :P 02:21
lue Any particular reason you want to stuff the subs in the role too, ooc? 02:22
Mouq Mmm, no reason in particular, though I want to be able to add a multi-candidate to pw-recurse in PTH and I guess putting them in the role made me feel that it was more likely to work :P 02:23
lue Are classes a necessity for a Pod::To:: module anyway, or would your role-based solution suddenly force its user to make a class? :) 02:24
Mouq They're not necessary but it sure cleans things up. Right now my hackity solution is to have method render (PTH :U: |a) call self.new.render(|a) 02:26
Which means that leakage between documents shouldn't be the problem it has been in the past 02:27
But perhaps a class is needed for the documents, and PTH should really just be a collection of subs 02:28
Or maybe it'll just die with "Bytecode validation error at offset 136, instruction 23: truncated stream" 02:30
lue My idea is that you'd have an object to hold all of your functions in, and then a collection of multi subs in the module to help you use it. Still feels more classy than roley to me, but I can't say I know for sure what's best :) 02:31
Mouq lue: Classy would work too :) The main issue I'm haven't gotten around to addressing is that P2H switches between an 'html', 'inline', and 'raw or html-escaped text' mode 02:33
The only difference I can see about inline, though, is that Paras aren't rendered with <p>s 02:34
(Note that this is an issue regardless or sub/role/class structure of Pod::Walker) 02:35
*of
lue wonders if he should put everything under module Pod::Walker; so Pod::Walker::Callees.new(), Pod::Walker::pod-walk() ... 02:36
02:36 BenGoldberg left
lue Mouq: yeah, that sounds like you need a ~slightly~ more structured object than a plain string; something like class PodString { Str $.text; EnumTypeThing $.txtstate }, where $.txtstate lets you know whether its "html" or "inline" or... 02:37
Mouq lue: The issue is that the things that need to be processed as 'inline' are processed before they're known to need to be processed as inline. And sometimes a single function needs to process them as 'inline' or 'rawtext' 02:39
02:40 xenoterracide__ joined
lue How's that able to work at all? O_o 02:40
Mouq lue: Well, that's what'll need to be resolved once I get it running. The way it used to work was because you manually called node2inline or whatever, but here the preprocessed text is handed to you. Which I still think is a good idea 02:41
02:43 ren1us joined
lue Mouq++ for working on it (and make sure to "lose" the enforced stylesheet while you're in there, eh? :P) 02:43

Mouq I really hate that the 'Cannot call X, none of these signatures match:' doesn't show the capture its matching against 02:48
At the same time, a .perl of an arbitrary call can be crazy verbose, so.. 02:49
lue I also don't like how warning messages won't show a backtrace on -j and -m like it does on -p, meaning every UVOTA just stands to infuriate you. I looked at it earlier, and I don't immediately see how to change that, though :/

hoelzro #= is currently treated as leading

Mouq Should we deprecation cycle that? I know there's a lot of code that wrongly uses #= 02:59

02:59 btyler joined
lue could see #^ for leading and #$ for trailing instead of the current ones :P 02:59
isBEKaml hoelzro: maybe I'm missing something here. What's the distinction between leading and trailing comments?
02:59 btyler left
isBEKaml Are they separated by where they are placed? That is, above or below a sub/method? 03:00

hoelzro isBEKaml: github.com/perl6/roast/blob/S26-WH...why-both.t 03:00

hoelzro I wish it would be #< and #>, or even #↑ and #↓ 03:02
I've been working on this for nearly a week and I still get them mixed up =/
lue hoelzro: #^ and #$ would offer some correlation with regexes :)
hoelzro lue: oh, true
Mouq: I would be happy to start filing PRs against "broken" modules
at least this change shouldn't alter behavior (unless someone's depending on WHY) 03:03
lue hoelzro: different symbols would make "deprecating" sooo much easier too. How do you know when #= is being deprecatingly used as a leading comment, anyway?
isBEKaml hoelzro: I can understand #| as a leading comment. Other languages such as Scala and Haskell use it for setting fixed spacing in doc strings.
hoelzro interesting, I didn't know that

isBEKaml: I never knew about --|
isBEKaml lue: too bad we can't turn into .lp6. :D
hoelzro that's not new, is it?
isBEKaml: hmm...a custom grammar for literate Perl 6? 03:07
lue hoelzro: no silly, that's the Pod sublanguage, not the comment sublanguage :)
hoelzro interesting idea
lue: heh
isBEKaml hoelzro: yep, haddock does it.
hoelzro: I'm not sure how far we can push .lp6. With separate comment formats like this one, I don't think we can see any literate forms - like lue said, at best it's a comment sublanguage. :D 03:09
hoelzro I suppose
still, it's an interesting idea 03:10
lue isBEKaml: not that you couldn't write a Literate slang to do that (once we know what it would look like to work in that realm of madness, that is ☺)
isBEKaml Currently, comments are read in tandem with code. With these forms, it'll feel like reading two books at once. :P 03:11
03:11 _slade joined
isBEKaml lue: exactly - let's see where that descends into madness. :-) 03:11
Frankly speaking, a lot of ideas in Perl6 spec feel like moonshots. 03:12
lue I think it's called "extensible programming", though I don't much like that name, particularly considering how much of P6 you can extend already. The ultimate goal is to change what the compiler is doing. Perhaps "cooperative programming"? :P
isBEKaml lue: hmm, isn't that what "extensible" stands for? 03:15
isBEKaml doesn't like to see it in non-lisp languages *ducks*
lue Yeah, though I really think manipulating the grammar and ASTs and whatnot of the language is far different from the *other* extensible aspects of Perl 6 that are implemented already, hence the desire for a distinct name :) 03:16
isBEKaml: the nice thing about a non-Lisp language is that it should be easier to tell what stuff is modifying the compiler's behavior :) 03:18
Mouq lue: Lookie what I made gist.github.com/Mouq/b04e9408cd0e83cf62bc 03:19
lue Lisp's macros and such have a nasty habit of not looking different, which on the one hand is the point of Lisp's syntax, and on the other hand makes it bleeding impossible to know what the distinction of a macro is.
Mouq (some obvious bugs)
Mouq really likes Rust's macros
lue Mouq++
isBEKaml lue: Right, it stands out in non-lisp languages. But if you read through a wide swath, it's easy to pick macros in lisp too. I just count defmacros, progns and some quirky naming conventions for macros in lisp. 03:20
lue Mouq: yes, I remember finding a (I think) Rust doc on macros that was quite interesting. Need to look at them more, 'cos they are quite possibly the only non-lisp language to have done Proper Macros™ thus far.
isBEKaml: my point is that it's kinda hard to tell what a (defmacro) does different from a (defun), because the code tends to look really similar. I remember reading some elisp documentation on it once, and although it did explain the difference, it was hard to believe that it's a necessary one. 03:21
Mouq doc.rust-lang.org/guide-macros.html
isBEKaml lue: I should have added this: Otherwise, I agree. :D 03:22
03:22 atroxaper joined 03:27 rurban1 left
lue Mouq: looks nice, makes me think our macros should really be some sort of grammar/action rule pair that gets injected into the current language. Still needs some sort of ast manipulation thing though. 03:30

.tell lue hello, my not finished yet solution is github.com/atroxaper/Pod-SAX. You can see Pod::SAX::Reformer class and its test. Main feature that my Callees makes a calls for start of Pod object, end of Pod object, and 'in' Pod object that trigger if .content has not Pod object like String. And for each Pod type we can make many callbacks for many cases. Like only for L<> but not for C<>, I think it is more flexible and maintenanc[fu
l] :) And you can share some storage with data between callbacks. And when we have start, in, and stop calls then we have something like Automata (en.wikipedia.org/wiki/Automata_theory) with states. And one more think. System of Anchors (i'm not sure with name yet) that objects contains a code that should be executed after all work and push its result to result represenation (like HTML). It can be used for crossrefs of many other things
.

jack_rabbit I'm reading docs that say parcels are immutable, but can contain mutable containers, so my $x = 1; my $parc = (0, $x, 2); $parc[1] = 3; works, but $parc[0] is immutable. 08:17
How can I put the *value* of $x into the parcel to make the second element immutable, rather than putting the container itself? 08:18

lizmat I'm open to suggestions to improve the message :-)
you could argue that %a<b> = %b should also be disallowed 09:42
it should be %a<b> = $%b
it's the automatic itemizing that's making it a unclear 09:43
jnthn It's not surprising if you stop to think for a moment
yoleaux 09:03Z <nwc10> jnthn: I made you a test case (slightly smaller): paste.scsys.co.uk/407345
jnthn %h<a> is clearly a scalar
And so provided you know what $s = %h does, %h<a> = %h2 follows fairly natural 09:44
lizmat ok, so from wider to narrower, we will allow transparently ($ = %), but narrower to wider is / will be an error (% = $) 09:45
is that something we can put in the spec ?

All the same, we shouldn't compile it to stuff that looks up a random attribute on the wrong object. :)

lizmat still it feels wrong: I mean, you can interpolate attributes in strings, and those are Str objects 11:51
(yes, I know it works differently underneath, but from a language point of view it feels weird) 11:52
I guess it is just another way of finding out that regexen are code, and not strings
hoelzro I've been working on improving declarator docs, so I've been doing some digging around in src/core/traits.pm. It made me wonder: why are docs implemented by applying an anonymous role against the object? 11:54
Not trying to be critical, just curious =)

masak_grr I just read shop.oreilly.com/product/9780596101992.do a bit more carefully, and it says "eval() in JavaScript should have been a keyword -- that would have solved so many static analysis headaches" 14:32
[Coke] masak_grr: any thoughts on EVAL being a macro as per spec? (right now it's a multi)
masak_grr [Coke]: EVAL being a macro sounds odd -- what compile-time effects is it trying to have? EVAL has *runtime* effects. 14:34
[Coke] Iunno. Spec says macro, 'sall. 14:35
moritz masak_grr: it has weird scoping
jnthn I think it's only macro in so far as the compiler is specially aware of it
Already the optimizer looks for the name EVAL to show up
masak_grr moritz: so do attributes, and they're not macros.
jnthn And if it doesn't, goes optimizing.
masak_grr jnthn: did you see the evaluation I did above? any opinions on that? 14:36
jnthn I think passing EVAL around is erroneous.
Unless we make it a macro 14:37

masak_grr I wonder if EVAL shouldn't be a statement prefix, then. 14:37

But oh, it'd not know it was a macro
So back to square one :)

jnthn I'll stick with "erroneous, on your own head be it" :) 14:38
14:38 Alina-malina joined
masak_grr I can accept/agree with that. 14:38
I just wonder if instead of the useless capitalization, we should actually limit the power of EVAL somehow. 14:39
for example by making it a keyword.
then you *can't* assign it.
jnthn True :)
14:39 locsmif joined
jnthn So far as escape analysis goes, anything in a lexical must be considered as escaping in absence of proof otherwise. 14:40
masak_grr well, my point was that anything might go on inside of the EVAL, and we don't even know it's an EVAL. 14:41
I'd much rather the language have a "nope" attitude to bad stuff, than an "on your head be it" attitude.
the *only* use case I can think of for assigning/rebinding &EVAL to other things, is to mess up static analysis. 14:42

masak_grr which example? could you re-run the one you mean?

[Coke] ... nevermind. the set to "yo" happens outside the def of twice, so it's all fine. would be less confusing with newlines. :) 15:14

FROGGS operator-rich is the right term I think
lizmat FROGGS: regarding 'perl6' and 'Perl6' 18:41
if I change the default language of EVAL to 'Perl6'
I get: No compiler available for language 'Perl6'
timotimo lizmat: aye, it needs a corresponding nqp::regcomp call somewhere
FROGGS yeah, rakudo/nqp use 'perl6' internally 18:42
lizmat having them differently, is asking for problems in the future, I would say
FROGGS true
lizmat so shall we try to standardize on 'perl6' or 'Perl6' ?
FROGGS I'd like to see Perl6
lizmat jnthn: do you have an opinion? ^^^ 18:43
FROGGS we talked about this when the JVM bindings were made
18:44 itz__ left
FROGGS and IIRC I "won" that time 18:44
(writing that language name correctly, that is)
because :from and friends are about a language, not about a compiler or interpreter

lizmat ok, I'll try to get it changed to Perl6 then ? 18:46

lue ren1us: seems like it. 20:32
ren1us i almost feel like circumfix should have the highest precedence, since it's the least likely to be triggered and most likely to trigger false positives on other prefix or postfix captures 20:34
jnthn Yes, termish is prefix* term postfix*, roughly.
And a circumfix is a kind of term
It's not that they compete, it's that the circumfix doesn't even get a chance.
