soh_cah_toa what is the Cool type for? is that mentioned anywhere in the spec? 02:20
[Coke] soh_cah_toa: perlcabal.org/syn/S02.html#The_Cool...d_package) ? 02:22
soh_cah_toa [Coke]: great, thanks 02:23
[Coke] de nada.
soh_cah_toa hm, this doesn't really make sense to me :\ 02:25
[Coke] best I could find. ;) 02:27
02:28 packetknife joined
jlaire soh_cah_toa: it's a common super class for all scalar types 02:28
or something like that 02:29
soh_cah_toa ok 02:30
colomon it's sort of the magic perl class... things which are Cool try hard to Do What You Mean 02:31
when I started with Perl 6, all user classes worked that way too, but then people noticed that meant the simplest class you could create had dozens (hundreds?) of methods on it. 02:32
soh_cah_toa yeah, spec says user-defined classes are not Cool
colomon so that functionality was filtered out into Cool, and if you want your classes to do all that stuff, you just add "is Cool" to them. :)
soh_cah_toa yeah 02:33
colomon But yeah, it lets you do stuff like... 02:35
benabik This class is Cool.
soh_cah_toa looks like it's most of the p5 builtin functions
benabik class This is Cool, sorry. 02:36
colomon rakudo: say (3524324 + 32222).split(/5/).perl
p6eval rakudo 317f89: OUTPUT«("3", "", "6", "46").list␤»
jlaire std: class This is Cool {}
p6eval std 8b331d2: OUTPUT«ok 00:01 118m␤»
colomon Many (most?) of what you'd think of as string or numeric methods are defined on Cool, so that you can call string methods on numbers, and vice versa. 02:37
soh_cah_toa ok 02:38
and does anyone know of a good blog/article that explains proto subs/regexes? they're not sitting well w/ me just yet 02:39
moritz soh_cah_toa: perlgeek.de/en/article/mutable-gram...for-perl-6 tries 02:40
colomon that's proto regexes, not proto subs, right? 02:41
moritz++
moritz: up with the wee one?
moritz aye, proto regexes
colomon: no, up by myself
soh_cah_toa moritz: in your example, what does the <sym> refer to in the rule definition? 02:42
moritz soh_cah_toa: in token sigil:sym<$> { <sym> } 02:43
soh_cah_toa yes
moritz soh_cah_toa: the <sym> is '$'
soh_cah_toa is 'sym' just a name your chose or can it be anything? 02:44
like token sigil:foo<%> { <foo> }
moritz soh_cah_toa: in rakudo, it must be 'sym' 02:45
soh_cah_toa ok
moritz soh_cah_toa: not sure if general Perl 6 permits any identifier
soh_cah_toa alright, but what about proto subs/methods? they seem to be very different 02:46
soh_cah_toa is looking at src/core/Cool.pm, btw
colomon yes, very different
moritz lemme try 02:47
colomon moritz: go for it, I need to get to bed. ;)
o/
moritz to the outside, a bunch of multis looks just like single sub or method
colomon: sleep well
and this single sub or method is a 'proto'
so if you take a reference like &foo, that's a reference to the &foo proto 02:48
the proto is then responsible for re-dispatching to its multi candidates
and there's a special syntax for redispatch, it's just proto sub foo(signature) {*} 02:49
soh_cah_toa but doesn't every multi sub/method do that even w/o a proto?
moritz but the proto could do something else, like first modifying its arguments before re-dispatch or so
soh_cah_toa: there are no multis without a proto in perl 6
soh_cah_toa: for subs the proto is just autogenerated 02:50
soh_cah_toa ah, ok
dalek ast: 6a6cd4f | Coke++ | S02- (5 files):
niecza fudging
soh_cah_toa alright, consider this:
proto method subst(|$) {*} 02:51
multi method subst($matcher, $replacement, *%adverbs) {
self.Stringy.subst($matcher, $replacement, |%adverbs);
}
when, subst() is called, the proto first flattens the args then re-dispatches?
moritz soh_cah_toa: no, it doesn't flatten the args
soh_cah_toa: in a signature, |$foo means "capture the rest of the argument list in $foo"
soh_cah_toa isn't that slurpy * though? 02:52
moritz and |$ just means "capture the rest of the argument list in an anonymous variable", or phrased differently, "do nothing"
soh_cah_toa: no, the {*} means "redispatch to all the candidates in here"
soh_cah_toa i meant in a sub signature
moritz that's not part of the signature, but part of the routine body
soh_cah_toa sub foo(*@foo) 02:53
vs
sub foo(|@foo)
i thought | flattens and * slurps
02:53 packetknife left
moritz soh_cah_toa: I think you're confusing a few things here 02:53
on the call side, foo(|@args) flattens 02:54
but in a signature, (|$foo) means "capture the rest"
soh_cah_toa ah
then what about * in a sub signature? 02:55
02:55 tyatpi joined
moritz * slurps 02:56
but *@foo only slurps positionals
and *%foo only slurps named 02:57
|$foo takes 'em all
soh_cah_toa and *$foo is positionals too?
jlaire std: sub f(*$) { } 02:58
p6eval std 8b331d2: OUTPUT«ok 00:01 120m␤»
03:00 xinming_ left
soh_cah_toa so like in the example above, is proto sub foo($|) {*} the default autogenerated proto? 03:01
s/$|/|$/
moritz soh_cah_toa: yes
moritz doesn't know what *$foo does
soh_cah_toa then isn't explicitly specifying a proto method (in Cool.pm, that is) a bit redundant as they don't actually do anything before re-dispatching? on that note, why is subst() even declared a multi in the first place? it only has one definition 03:02

sorear ah
jnthn Also curious why we see it twice.
moritz it's supposed to be a runtime error
06:27 lichtkind left
sorear jnthn: the twiceness is correct. You're matching the regex against a string with two indexes 06:27
The cursor can either be at 0/1 or 1/1, and <$x> has to be tried at both places
and $x could in principle have been modified, so reusing the eval is a matter of optimization 06:28
jnthn ah, makes sense
(no coffee yet today :))

moritz so if a role has an attribute, I can neither use it in a class that I compose the role into, nor can I declare one on my own 12:33
that seems LTA to me
masak agreed. 12:34
jnthn Agree but not sure what to do about it.
It's a language design call really.
If we decide what's wanted I can probably work out how to do it. 12:35
12:35 bluescreen10 joined
moritz well, either we make attributes private to roles, or we compose them into the class 12:35
jnthn In master we didn't try to check attributes at compile time so never ran into this. It just magically worked.
moritz: "private to roles" still involves them being copied into the class. 12:36
tadzik b: role a { has $!a }; class b does a { method foo { $!a }}
p6eval b 1b7dd1: ( no output )
tadzik that's what I'd expect
jnthn We can do that, it just means that we have to keep track of every attribute used in the class body, and then check them after composition has taken place.
(at the point we parse the usage of $!a, we don't yet know about the one in the role) 12:37
colomon phenny: tell mberends You can get an extra 1000+ tests by turning on the trig tests (except atan2, which isn't fudged for niecza yet). With TEST_JOBS=8, they make "make spectest" take about an additional minute to run on quad-core MBP.
phenny colomon: I'll pass that on when mberends is around.
jnthn (since role composition happens at the closing } of the class)
Changing it to do what b does is the easier of the two options. 12:39
moritz I'd be fine with either way

felher I just saw jnthn++'s grammar debugger and the exporthow-thing seems to be rakudo specific, isn't it? Do the specs specify a method to do something like that (yet)? I.e.: would a fully working P6 implementation of todays specs be able to do something like that without requiring hacking on internals? 14:23
jnthn felher: There's no spec'd way to do it just yet. The Rakudo way isn't hacking on internals really though, it's just sticking some stuff in a package. 14:24
felher: I'd like to see something standardized there
But I'm not totally happy with EXPORTHOW as the mechanism just yet.
It's incomplete anyway

supernovus moritz: Ah ha. I need to learn more about Match objects first. I'm trying to find a list of submatches (this is from a grammar parse) in a parent match. I'll dig into the code, maybe I'll come up with a .perl method while I'm at it :-) 17:54

TimToady so the user can think of their outermost class as the root
and for consistency, but I see the argument for inconsistency 18:00
and it doesn't make much difference for attributes, since Any and Cool don't have any

supernovus that's interesting, its parsing a grammar, and the stringified match shows the full match, but any optional captures such as <attributes>* while being parsed, are not included in the caps (and thus $node<attributes> returns nothing...)

sorear out.
moritz that doesn't make the match fail 18:24

TimToady sorear, mberends: the why-not would be that $command_tail would not be portable to *nix, if we restrict run to execve semantics
and the point of splitting out shell() was to do that, I thought 18:26
so shell("$file $command_tail") is closure to the win semantics 18:27
or run needs to accept multiple args, and glue them back together for win 18:29

mberends TimToady: true, I have some C code somewhere to iron out the Win32/*nix wrinkles, not sure how well that would port to C#. I hope I can find it, only half a chance because I'm in away from home for two days.
supernovus Yeah, if I remove the * from the <attributes> rule, it returns the found attribute (but also makes it so that elements MUST have an attribute.) So for some reason, if you use * on a subrule, it will match the rule, but won't include it in the captures.

Very preliminary implementation of inlining chosen multi-dispatch candidates. So far, a routine is an inlining candidate iff it consists of a single statement, made entirely of pirops and its arguments, with strictly one use of each argument. Regresses two test files, which ain't bad given this is the very first shot.
 23:29
tadzik that looks promising 23:30
does that inline $a + $b for example?
jnthn tadzik: If it knows enough about their types, yes.
tadzik: And if that type information lets us resolve the dispatch candidate at compile time. 23:31
tadzik so Int $a = 5; Int $b = 7; $a + $b can possibly inline, or that'd have to be native ints?
jnthn Here it reports it inlined the + call there. 23:32
We do have a bit of a problem though :(
A load of multi candidates are marked with :D and :U
This totally hoses inlining. 23:33
Anyway, this is a reasonable start. 23:34
