jaffa4 I have a small class example.. Should I work? 07:33
gist.github.com/jaffa4/65d3e848cf08024957b0
if you run it you should get 4
moritz jaffa4: no 07:35
masak morning, #perl6
moritz jaffa4: only attributes with accessors are automaticaly initialized by new/bless
wouldn't be very private if you could initialize it from the outside, no?
masak jaffa4: easy fix: write `has $.b;` with a dot
jaffa4: which means that you can also writhe `$c.b` instead of `$c.get` -- double win :) 07:36
jaffa4 and what is the other way?
What is the weather like in Sweden?
masak sunny. 07:37
jaffa4: the other way, the one you wrote? `has $b` is just a bad way to write `has $!b` 07:38
moritz the other way is to write your own BUILD method that sets the attribute

m: say time()-1
camelia rakudo-moar 89847f: OUTPUT«5===SORRY!5=== Error while compiling /tmp/wiVssWgBAL␤Undeclared routine:␤ time used at line 1␤␤»
moritz time is a term, not a subroutine 07:56
though I still wonder if maybe that causes more confusion than it's worth
m: sub mytime() { time }; say mytime - 1
camelia rakudo-moar 89847f: OUTPUT«Too many positionals passed; expected 0 arguments but got 1␤ in sub mytime at /tmp/0QWSaCwmSU:1␤ in block <unit> at /tmp/0QWSaCwmSU:1␤␤»
moritz why don't I get a compile-time "will never work" error here? 07:57
oha moritz, i actually thought that part of the confusion was the dash
moritz oha: yes
oha: it's just that time() doesn't work because it's not a sub, and it's not a sub so that 'time -1' can work 07:58
oha otherwise the -1 will be considered an argument, i see that now 07:59
but so, if it is a term, why time -1 works, and not time-1?
if time-1 is parsed as a "ident" then why it complains about "time" and not "time-1"? 08:00
masak m: sub mytime() { time }; say mytime 5 08:03
camelia rakudo-moar 89847f: OUTPUT«5===SORRY!5=== Error while compiling /tmp/L5DhaYWctd␤Calling mytime(int) will never work with declared signature ()␤at /tmp/L5DhaYWctd:1␤------> 3sub mytime() { time }; say 7⏏5mytime 5␤»
masak moritz: because `5` is a constant, but `-1` is a very complex expression :P
08:04 telex left, dakkar joined, telex joined
masak thinks that if Perl 6 just decided that -1 is a constant too (like in parameter context), that would eliminate a set of confusing cases and the world would be a better place 08:05
jaffa4 Why is binding used in BUILD method example? 08:07
oha masak, although, say time-$x; would fail anyway
jaffa4 in there doc.perl6.org/language/objects#Object Construction
masak jaffa4: which example is that?
08:08 vendethiel left
jaffa4 section object construction 08:08
class EncodedBuffer <<<<<<< 08:09
oha i'm actually thinkg, is abc-123() a valid method name? it seems that after a dash you need a letter, as in a12-b34() so why is time-1 or time-$x confusing at all? 08:11
(sorry if i'm silly, i'm just really curious)
jnthn abc-123 ain't a valid method (or sub) name 08:13
std: say time-1
camelia std 28329a7: OUTPUT«ok 00:01 136m␤»
jnthn In Rakudo's grammar we have:
token term:sym<time> { <sym> <.end_keyword> }
Where 08:14
token end_keyword {
» <!before <[ \( \\ ' \- ]> || \h* '=>'>
}
And that - in there is why we reject it
I don't know off hand whether it's Rakudo or STD that's out of line here.

08:15 FROGGS joined
jnthn That's certainly a sub name, and wins on longest token semantics. 08:15
oha jnthn, yeah, i sort of expected it
jaffa4 What is the implementation of the build-in parser? 08:16
What type of parser is it?
jnthn jaffa4: It's implemented as a Perl 6 grammar, which is a PEG, with longest declarative token as the key disambiguator 08:17

RabidGravy so I halved the time to encode a wav to mp3 by cutting out the intermediate arrays - if I could cut out the CArray -> Buf -> .write step it might even be usable 08:27

Tad_ Is perl 6 arrays different from perl 5 arrays 08:34
jaffa4 in what way?
jnthn They're different in various ways. 08:35
08:35 llfourn joined
jnthn jaffa4: Not sure off hand 08:35
Unlikely though 08:36

masak Tad_: could you be more specific? there surely are ways to use Perl 6 arrays exactly like Perl 5 arrays, but that doesn't mean they're completely the same. 09:00
09:09 espadrine left, vendethiel left 09:21 vendethiel joined 09:23 ShimmerFairy joined 09:24 Hor|zon_ left
moritz Perl 6 arrays are potentially lazy, so yes, they are different 09:26
also, they have methods
Perl 5 arrays aren't objects
jaffa4 number of elements:: @a.elems.... 09:28
moritz though you can still just use the array in numeric context to get the number of elements 09:31
jdv79 is there "slush" period coming up? 09:33
sept sometime maybe? 09:34
jnthn I really hope by sept we'll be done with the major semantic tweaks. 09:36
And can focus on bugs, performance, polish.
jdv79 very nice 09:37
jnthn The GLR and multi-dim stuff are the two big areas, but I'll be giving concurrency stuff a good going over in the near future too 09:39
CIAvash is 'is cached' for methods going to be implemented anytime soon?
jnthn CIAvash: Well, we talked a bit about how it might be done at some point, at least... 09:41
jnthn noted that it probably wants to be a per-instance cache
09:42 vendethiel left
jaffa4 Is this wrong? @(%!list{$group}).push:$entry; 09:45
jnthn Don't see why you need the @(...) 09:46
In fact, putting it almost certainly will break things. 09:47
jaffa4 It did not push
yakudza omg I thought @{@{%{$blabla notations are left in perl5 (:
jnthn Yeah, I won't
*it
It'll probably coerce to a throw-away list, which you push to
You just want to %!list{$group}.push: $entry 09:48
It'll even auto-viv an array
If there ain't one there already
jaffa4 that did not seem to work
jnthn Then you probably did it wrong.

jnthn But you rarely need it at all 09:50
Since depending how you want to see it, everything is a reference, or there are no references :)
yakudza m: my $x = [0..9]; say $x; say @($x); 09:52
camelia rakudo-moar 89847f: OUTPUT«0 1 2 3 4 5 6 7 8 9␤0 1 2 3 4 5 6 7 8 9␤»

camelia rakudo-moar 89847f: OUTPUT«0 1 2 3 4 5 6 7 8 9␤»

Makes sense though
Since it's potentially ambiguous with a colonpair in a method name.

10:24 mr-foobar left
jaffa4 Is it easy to write a module to extend Perl6? 10:25
moritz depends on what exactly you want to extend
new symbols are generally easy
jaffa4 what if i added embedded Sql to Perl6?
Guest84398 Can you use inline assembly with perl6 code 10:26
moritz jaffa4: I think you'd have to write a slang for that
jaffa4 Does slang work?
moritz Guest84398: possibly via Inline::C
jaffa4: not as nicely as we want it to do, but FROGGS++ has written several already 10:27
jaffa4 What did he write?
moritz jaffa4: modules.perl6.org/ search for slang 10:28
3 are from FROGGS

itz isn't it defined as BNF? (vague memories of CS of decades past) 11:29
DrForr ANTLR? Hardly, closer to PEG or LALR(inf). 11:30
itz no pascal
DrForr Probably, but it's easier to convert someone else's grammar.
And lets me check out the output from the parser converter.

itz "constant LIB = sprintf $*VM.config<dll>, "curl";" is probably more portable than hardcoding .so everywhere .. was wondering if this sort of thing belongs in NativeCall itself though 14:26
timotimo nativecall already has a bit of code in it that tries to guess a library name
sadly, it doesn't have a way to figure out if a given name is right, so it'll decide on one candidate and then it's hit-or-miss 14:27
itz ah of course :)

FROGGS constant LIB = 'curl' # should hopefully good enough 14:27

masak right. especially given `lines` is already a sub, why not `words`? 14:44
smls should 'words' without args also read from $*IN like 'lines' without args?
masak no, IMO. 14:45
it's kind of a historic accident that `lines` does, even.
smls fair enough 14:46
masak also, it's easy in retrospect to decide to allow `words()` and have it mean that... but not so easy to back out of/deprecate.

masak I think the current behavior makes more sense than * meaning Inf... 20:01
if you want Inf, write Inf 20:02
AlexDaniel haha
masak that's how I often feel about people writing * when they mean Inf, though, so I'm not sure that's a majority view... :)
AlexDaniel masak: just reported this: rt.perl.org/Public/Bug/Display.html?id=125627
PerlJam How do you mark an RT ticket as "tests needed"? 20:03
jnthn PerlJam: Jumbo
PerlJam danke
jnthn bitte
masak if it's in Jumbo, it's also in one of the smaller ones :)
jnthn

AlexDaniel masak: so, what can we do about it?
does not sound like rakudobug
20:05 _mg_ left
masak AlexDaniel: change the spec to conform with implementation, far as I'm concerned. 20:05
jnthn I think I'm good with that.
[Coke] PerlJam: Custom Fields, Tag, add testneeded (tag is multiselect)
AlexDaniel masak: Well, I'm not the one to change the spec, especially when I'm unsure. But I can fill a bug report 20:06
jnthn x auto-currying feels more helpful
20:06 llfourn left
AlexDaniel masak: so where should I report problems with the spec? 20:06
[Coke] github.com/perl6/spec/issues
AlexDaniel great
[Coke] er, github.com/perl6/specs/issues
jnthn AlexDaniel: Why ain't you? It's under version control, enough of us here seem to support the change, if it's disliked then revert is easy :)
masak AlexDaniel++
jnthn The design docs ain't holy :)
(Of course, an issue is welcome too.) 20:07
AlexDaniel jnthn: you are right. Maybe next time :)
PerlJam needs to play with RT more to get used to the interface. 20:08
jnthn d3
oops
masak indeed, d3. should look at that more. 20:09
jnthn It's a script that builds day 3 of the course slides I'm working on from source. :P
And opens them in a PDF viewer :) 20:10
masak ooh :)
lucasb one script of each day? :D
jnthn yeah :P
I don't teach anything longer than 3 days, though :P
lucasb oh, good
jnthn 3 days of me is enough for anybody. 20:11
PerlJam makes a mental note to ask jnthn's wife if she only takes him in 3 day doses 20:12
I'm 1.5 months shy of my 20 year anniversary and I think there might be some wisdom to limiting spousal exposure as far as marital longevity is concerned. :-) 20:15
cognominal jnthn, that's false. I fell asleep at your teaching but that was me exhausted, not because of your teaching 20:16

20:40 darutoko left
timotimo i think the YAML module isn't working properly any more ... or at least the tests can't run (because TestML is incomplete or bitrotted) 20:41
masak why does YAML have a dependency on TestML? 20:42
timotimo in order to run its tests
ssqq Have any similar module like YAML could lookup data with indent? 20:43
20:43 kyclark left
timotimo the to-json we have in core (but don't rely on it staying around) does indenting, too 20:44

i must admit the last time i looked at it must have been a year ago or earlier
ugexe he is on win32 i think
RabidGravy well, that code gives nasty error
I think it needs some love
ssqq I think the best way is save data with JSON, and view it with Perl5<YAML> 20:47
20:47 ssqq left
timotimo right, you can use Inline::Perl5 to use perl5's YAML module 20:48
RabidGravy I'll have a look at that in the morning, got to have a working yaml parser

masak as it should. 21:23
lucasb "--optimize=off" is the right way to turn it off?
masak but that one failed before.
isn't it --optimize=0 ?
lucasb oh, I maybe a confusion; it fails with or without the optimize :)
21:23 TEttinger joined
masak right. 21:23
21:23 lizmat left
lucasb *I made a... 21:23
I wish --optimize=0 also work to turn it off, but I guess it really wants the string "off" 21:25
masak ok
21:32 kyclark joined
jnthn off and 0 are different 21:33
off means "don't even do the analysis"
0 should mean "do the analysis but no optimizations"
So you can isolate analysis crashes from transform crashes. 21:34

dha Documentation query: Currently, C<//> and C<orelse> are defined differently in the docs. C<orelse> seems to reflect the current behavior. It has been mentioned here that this behavior may change. 22:22
Should the doc for C<//> be corrected for now, or should we wait until the implementation is settled?
22:23 RabidGravy left
masak dha: not sure I understand. 22:31
dha: C<//> and C<orelse> do have different behaviors, so they should probably be described differently. 22:32
dha Well, they have different precedence. Their returns should not, AFAICT, be different. 22:33
timotimo orelse is a statement-level infix, which is why it's not insane that it sets $! on the RHS
dha C<//> says that it returns the first defined operand, but that is not the case if there are no defined operands.
C<orelse> specifies that it returns the last operand if none are defined.
timotimo ah, yes
that part ought to be added to //, too
dha C<//> certainly seems to behave that way as well.
timotimo that it returns the last one if no one was defined
masak m: sub foo { fail 42 }; foo() orelse say $! 22:34
camelia rakudo-moar b606f9: OUTPUT«Nil␤»
timotimo masak: "is supposed to", i think
masak aye.
NYI.
dha right. But TimToady mentioned when I was first looking at this that at some point it might return Empty, rather than the last operand. So...
22:34 mr-foobar left
masak I'm not sure why the `()` are required there, if `orelse` is a *statement*-level infix. 22:34

looser precedence isn't the only difference. 22:43
dha What else is there? 22:45
22:46 telex left
masak the setting of $! in the rhs thunk 22:46
dha Also, I'm not proposing saying they're the same, just adding the implemented behavior to the ?? doc.
sorry. //
masak what implemented behavior? what do you feel is missing from the // doc? 22:47
dha That it returns the last operand if no operand is defined, rather than what it says now which is that it returns the first defined operand, period. 22:48
(Granted, I haven't looked at the implementation, but that certainly appears to be its behavior)
22:48 telex joined
masak docs for || has it right 22:49
"Returns the first argument that evaluates to True in boolean context, or otherwise the last argument."
(except that it refers to the operands as "argument". that's needlessly routine-centric.)
dha That doesn't change the fact that the doc for // says "Returns the first defined operand." 22:50
masak *nod*
yeah, please fix that.
dha Ok. 22:51
masak 'night, #perl6 22:52
dha Actually, I'm not clear on the procedure here. If I change it in the doc repository on github, will that propagate to the actual website at some point, or do I need to patch in two places?
22:52 yqt joined
dha Oh, and also, if C<orelse> *isn't* the same as infix //, we should probably change that as well, but I'm not fully clear on what to change it to. 22:53
