diakopter TimToady: maybe - is an optional prefix on a decimal/integer token, so LTM gets it. 00:12
TimToady that'll screw up -2**4, which is usually meant -(2**4) 00:13
since in math it's usually written -2⁴ 00:14
we might be able to get away with ^10 as a literal though 00:15
won't help with -8.abs though
we started going that direction with -3+2i but it was turning into a Bad Idea 00:16
diakopter ---8.abs "emphatically negative" 00:17
TimToady and -1/7 was a mess, as you discovered :)
diakopter yes
TimToady so we'll probably leave quo the status 00:18

lichtkind i dont get the parameter trait dynamic 12:11
cognominal "As far as I can see, it proposes to undo the generalization that led ? quantifiers to produce empty lists.". I wish I had expressed that so clearly.
masak++
lichtkind the sentence is: Specifies that the parameter is to be treated as an "environmental" variable, that is, a lexical that is accessible from the dynamic scope (see S02). 12:12
does that mean a eg $a parameter is mapped to $*a ? 12:13
dalek p-rx: 40bb2a8 | moritz++ | docs/bootstrapping.pod:

lichtkind no suggestion? 12:16

lichtkind moritz_: a like local var, thank you very much 12:18
moritz_ please don't use that term, it's confusing 12:19
lichtkind i ment it in the way: what we define in perl 4 and 5 as local
moritz_ I know. Still please don't use it in the context of Perl 6 12:20
12:20 plobsing joined
cognominal moritz: the point of my idea is that it is specific que the '?' quantfier. zero or one, is not naturally represented by an array but by something present or missing. 12:20
s/que/to/
moritz_ it's even in Perl 5 confusing
because people think of "local vars" as what my() provides 12:21
cognominal: still it blurs the distinction between a successful-but-zero-times and a failed submatch
cognominal: maybe it's worth it - I don't know 12:22
I just wanted to mention the points that came to my mind while reading the proposal
cognominal I indeed agree that it blurs this distinction. 12:23
moritz_ if you really care about it, you can introduce an outer capture as a workaround
$<outer>=[<inner>?] 12:24
masak I'm very uneasy with such a change.
but I can't pinpoint why.
maybe pmichaud has something to say about this.
12:24 am0c left
moritz_ I'm quite sure he has :-) 12:24
cognominal The strongest argument against my proposal is indeed that a successful-but zero-times match does not appear in the parse tree. On the other hand, that's my very point : suppressing them. 12:26
masak I think the lack of exceptions that led to the current design is the strongest argument against your proposal. 12:27
IIRC, we originally had it much as you proposed.
12:28 snarkyboojum left
cognominal I did not remember the orginal discussion, I just want to show the consequences with a Perl 6 grammar that has optional rules everywhere. 12:29
I would not be surprised that it does not hit other grammars heavily.
oops, double negation.
moritz_ mentallly removes a negation in an inappropriate place 12:30
masak the original discussion was many years ago.
2006 or 2007, perhaps.
it was either prompted by a request from audreyt or pmichaud, or both. 12:31
cognominal what was the original design?
moritz_ cognominal: maybe an interesting optimization would be to use a singleton empty list
jnthn Well, match objects are readonly iirc, so that could maybe work. 12:33
12:33 _jaldhar left, chitragupt left
moritz_ they only mutable part of match objects are the ASTs 12:33

cognominal My interest in not only parse tree generating less data, but also being more readable, I just find successful-but-zero-times submatch cluttering the parse tree. 12:35

12:36 [particle] left
cognominal When you read a parse tree of a siimple program it is cluttered with the reductions triggered by the most adanced features of the language. 12:37
masak seems at that time, S05 said "Quantifiers (except C<?> and C<??>) cause a matched subrule or subpattern to return an array of C<Match> objects, instead of just a single object."
cognominal Pedagagically speaking, it is wrong.

masak literal: what do think about the u4x readiness of grok.
literal [Coke]: something like that
masak literal: we never really got to that point during that project, mostly due to lack of u4x :)
literal I need to look into this stuff some more again
I read somewhere that the NPW scheduled this weekend is all but cancelled due to the ash 12:52
is that true?
masak [Coke]: it might help to see the README, but my dream is basically that when the user sees e.g. a '^' in a Perl 6 program, she would type 'grok ^' and get help on the various constructs that might have a '^' in it.
moritz_ literal: yes
literal damn
masak yes. a real pity. 12:53
[Coke] masak: I'm assuming that grok should itself be written in perl6, and rely on the existing synopses ?
literal it's written in Perl 5 currently...
masak the implementation language isn't terrivly important. something that works.
[Coke] literal: where is grok now?
literal [Coke]: github.com/hinrik/grok
[Coke] masak: sorry, "ultimately" written in perl6. 12:54
masak aye. sure.
[Coke] er, no quotes necessary
masak it was probably wise of literal to choose Perl 5 for the project last summer.
[particle] it was wise enough to finish the grant

lemme fix
colomon master seems to be drastically more stable than alpha was.
[Coke] guess I forked too soon. :P

isBEKaml moritz_: I have a little suggestion about the book. Since this is essentially a learn-as-you-code (code-as-you-learn as the case maybe :) ) approach, I feel you don't need to include answers to exercises at the end of the chapters.
moritz_: Instead, since the API can change over time, maybe you can just include some stable methods and additional ones to play with? 14:18
moritz_ isBEKaml: maybe the answers should go at the end of the book
masak aye. 14:19
moritz_ but they should be included if people don't find out themselves - research on minimal-guidance based learning suggests it's necessary
isBEKaml: uhm, which API are you talking about?
(or at least for some of them) 14:20

isBEKaml no, not exactly. Problem statement, hint states some function that we can use. Now, have a look at this function/op and see what it does. If you don't understand, there's the glossary/IRC. ;)
moritz_ masak: except that it doesn't work with our book
masak why not? 14:31
moritz_ isBEKaml: that's actually a good idea

jnthn: Hi!
jnthn: I'm looking for... a better way for Parrot to recognize callables.
jnthn: blizkost currently uses VTABLE_isa(INTERP, $obj, 'Sub') 18:45
but there are plenty of non-Sub callables... like oh Perl6Sub
I'm thinking this is going to need a multi-faceted fixz 18:46
1. add a 'callable' interface to Parrot, like our current 'array', etc
2. make P6opaque support 'callable' iff does 'postcircumfix:<( )>' 18:47
3. use 'callable' in blizkost
18:47 gurjeet left
sorear P6opaque already forwards VTABLE_invoke to postcircumfix:<( )> 18:47
18:47 uniejo left 18:48 gurjeet joined, uniejo joined
[Coke] sorear: you probably want something like "does Callable" (which is not set on a Sub, MultiSub, or an Eval, but can be in about 5m.) 18:58
[Coke] catches up. Right. what you said, with does. =-)

sorear [Coke]: none of the Rakudo base classes actually inherit from PMCs iirc. It's delegation all the way down. 19:10
[Coke] sorear: would it be helpful if you could ask VTABLE_does(interp, pmc, "Callable") ? 19:12
sorear yes
diakopter TimToady: (cont. previous "everything's a closure" thread), this means lexicals declared in the block also become uninitialized, unless of course they are "state" variables...?
TimToady yes, the block is called repeatedly by the implementation of loop, and Perl doesn't care whether it's a "built-in" or something the user cooked up. 19:14
diakopter ok.
sorear the default slang has special syntax for for but that can be overriden
TimToady if you want a fast loop, there's always 'redo' and 'goto'
diakopter reallocates mental resources to tricksiness
jnthn sorear: May we that we need a vtable override in Mu.pir for the does vtable method. 19:15
sorear jnthn: P6opaque would be more correct IMO as that's where our 'invoke' lives 19:16
jnthn And also inconsistent with all of our other vtable overrides. 19:17
(Aside from invoke.) 19:18
The only ones that live in the PMC are in there because they need to be.
19:20 sahadev joined
diakopter I just remembered I already accounted for this. doh. I should write more comments. my code is not very self-documenting. even the code I wrote a few days ago. 19:22
TimToady perhaps you should consider writing in APL, since Unicode now supports that... 19:23
[Coke] conveniently, we have an APL for parrot.
(a very crappy, broken one, but still!) 19:24
diakopter pretends not to be nonplussed... oh nm

TimToady wow, making STD parse the insides of character classes makes it really upset with itself...

sorear I wonder how reasonable it would be to use Perl 6 itself to build a language implementation... we've got this wonderful grammar engine. 19:35
arnsholt I had a similar problem with NQP. There's some code that panics with a Perl 5 compat message when there's a - in a character class

diakopter sorear: re "I wonder how reasonable... ": LOL. but, that's the goal (as stated in S01, at least). 19:39
pmichaud This is why neither PGE nor NQP have worried about parsing things like \s, \S, \d, etc. inside of character classes :)
actually, parsing wouldn't be too bad, it's making them do something useful that is the pain point :-)
jnthn sorear: Yes, but that won't help entirely since we wrap Parrot subs. 19:40

so it doesn't get that far at all
that's the trampoline
22:04 chitragupt joined
pmurias why doesn't it catch a specific Exception class 22:05
?
masak ooh, someone in my vicinity who uses the word 'trampoline'!
what's a trampoline, and how does it differ from a continuation?
diakopter it could catch NullReferenceException
it's just there for when next is null 22:06
so it doesn't have to check it every time
obviously in real user code, there would be user-level exception blocks
a trampoline can be a way to bounce reified frames
masak bounce... reified... frames. 22:07
diakopter refractalize.blogspot.com/2009/02/s...tions.html

thanks. will read.

masak I'm refactoring Yapsi tonight to pass 'environments' from compiler to runtime. an environment is simply all of the lexical scopes right now. I think that's a worthy abstraction to be using. 22:12
it will allow things such as BEGIN blocks and a proper REPL to work.

lue ō.o
masak diakopter: hm, there seems to be a confusion in my mind about that right now. 22:13
diakopter ahah.
masak which tells me I'm implementing it wrong.
scopes are not clonable at all in Yapsi presently.
diakopter in perlesque, a class is generated for each scope (actually just each frame, but effectively each scope).
that class has slots for each lexical declared in that scope. 22:14
masak how backwards :P

Bug closure :)

masak: what does the foo; on a line by itself do?
masak lue: it calls the sub by that name.
diakopter speaking of runtime, I'm starting to suspect I should just bite the bullet and write an "interpreted" (virtual method calls, not bytecode) edition of this parser generator. :| :| :| after all that work on writing ultra-efficient single-routine parsers.
masak diakopter: why? 22:19
I mean, what is making you realize that?
diakopter cuz the startup (JIT) time in both mono and .NET is pretty high for the single-routine parser
(only relevant during bootstrapping phases.. but still)
22:19 hejki joined

PerlJam Doesn't one of the synopses say that lexicals are available from the point of declaration to the end of the innermost enclosing scope?
22:24 sahadev left
masak jnthn: right. still reporting this one separately, just in case. 22:24
PerlJam Or is that just lexical *variables*/
?
I mean, if subs are lexical now, then I would expect foo(); sub foo { ... } to die too 22:25
jnthn PerlJam: I'd understood it as just variables.
masak PerlJam: subs are 'evaluated' at CHECK time or something of the kind.
PerlJam: so they're available textually before their declaration at runtime.
PerlJam That seems ... anti-lexical 22:26
or, anti- one of the salient features of lexicals according to PerlJam :)
masak I'm very grateful it works that way.
otherwise it'd be difficult to do mutual recursion, or even normal recursion. 22:27
22:27 am0c joined, nihiliad left
masak hm. maybe normal recursion would work. 22:27
still, it'd force everyone to declare subs towards the top of a file. 22:28
jnthn Yes, it'd be quite the nuisance.
PerlJam Sure, I don't disagree. I just want a good definition of "lexical"
lue thought subs are useless closer to the top :) 22:29

22:40 hercynium joined
sorear but they're still a nice, 100% static equivalent of method-shaped macros 22:40
so they could be good as a transitional form before we get true macros implemented 22:41

Tene I had a prototype of macros working, actually.
masak sorear: why do you ask?
Tene: what happened to it?
sorear masak: It's insane. And it's related to how macro implementation needs to work. 22:47
masak I'll definitely check it out.
Tene masak: It's still on my laptop somewhere. It was Perl 6 style macros for my scheme compiler.
masak thanks for the tip.
Tene: I remember you working on it.
Tene What's q:a:s ?
masak Tene: were you blocking on spec or something?
lue
.oO( spec definition of macro hertz my brain /o\ )
 22:48
Tene masak: Yes, there was one spec question I was blocking on. Still unresolved, afaik. I had a proposal, and TT was going to think about it. A limited subset would be fine to implement, though.
masak Tene: what was the proposal?
Tene masak: the body of a proto regex should be the default parsing rule for regexes in that class. 22:49
The macro stuff refers to a "default parsing rule" for grammatical categories, and assumes one for its examples.
I think it did in at least one example, at least. 22:50
Lemme look for an example.
22:51 IllvilJa joined
masak that soudns vaguely sane, I think. 22:51
but all this is predicated on people using macros anyway.
that's why it's important to have a working version out there for people to toy with, even a prototype. 22:52
Tene like, macro postfix:<{{{ }}}> { ... }
Or, better...
github.com/rakudo/rakudo/blob/maste...ar.pm#L444 22:53
If I want a new statement_prefix, the spec implies that I can just say:
macro statement_prefix:sym<OMG> { ... whatever } 22:54
and it would inherit the default parsing rule, which the grammar suggests is "<sym> <blorst>"
but that's not defined anywhere, so I would instead need to add: "is reparsed(/ <sym> <blorst> /)"
dalek ok: 228f280 | duff++ | src/subs-n-sigs.pod:
[subs] some clarifications and minor text changes
 22:55
Tene I'd instead prefer to see in the grammar: proto token statement_prefix { <sym> <blorst> }
and the body of the others as {...}
sorear Tene: have you seen the blizkost advancements? 22:56
masak diakopter: I pushed a change to yapsi 5 minutes ago, but it hasn't showed up yet.
diakopter sign.
Tene sorear: I've seen nothing at all. I'm excited to find out.
sorear github.com/jnthn/blizkost/raw/bb495...ples/tk.pl 22:57
Tene masak: So, you could implement macros with the requirement that all macro definitions contain a parsing rule.
sorear that. works in rakudo master.
masak Tene: that'd still be way better than nothing.
Tene sorear: That's very exciting. :)
