Kodi Defining &infix:<eqv> or &infix<cmp> on new classes simply doesn't work. Is that a reported bug? It is what causes most of the tests in series-nonnumeric.t to fail. 00:02

pugssvn r31469 | Kodi++ | [t/spec] Fixed another of my ", ..." typos. 00:09
sorear Kodi: Where is Alternating.v defined? 00:14
Kodi sorear: Whoops, you're right! That should be '.val'. 00:15
sorear Does that fix it?
Oh, wait 00:16
Kodi I'll fix that, but I've tested overloading eqv and cmp in simpler cases.
Let me make sure I'm not crazy.
sorear Overloads in Perl 6 are scoped, iirc
infix:<eqv>:(Alternating,Alternating) is defined only in that one block
it's not defined anywhere infix:<...> could see it 00:17
possibly changing to our multi would help
Kodi rakudo: class Foo {has $.v;}; multi infix:<cmp>(Foo $x, Foo $y) {$x.v cmp $y.v}; my $a = Foo.new(v => 1); my $b = Foo.new(v => 2); say $a cmp $b; say $b cmp $a; 00:18

Kodi Huh? 00:19
sorear Kodi: in that test, you're calling cmp directly
Kodi: if you call infix:<...>, the cmp overload needs to be somewhere ... can find it 00:20
ah
Kodi sorear: Bear with me, now. Why won't the dispatcher use that candidate.
?
sorear rakudo: class Foo {has $.v;}; multi infix:<cmp>(Foo $x, Foo $y) {$x.v cmp $y.v}; my $a = Foo.new(v => 1); my $b = Foo.new(v => 2); say $a cmp $b; say $b cmp $a; 00:21

p6eval rakudo 7102d7: OUTPUT«-1␤1␤»
sorear ok good I'm not just making this up
Kodi Huh. 00:22
sorear because infix:<cmp> is defined as a package-scope function, and you can't augment a package multi with a lexically scoped overload
Kodi So what's the scope of the cmp without "our"?
sorear my
private, lexical
Kodi I see.
Thanks a lot.
Is it intended that you can't have lexical instances of a package multi, or is that an implementation limitation? 00:23
sorear I don't know 00:24
probably intended

cuppe so...I'm new, and just playing around at the moment. was trying to figure out how to do constructors in perl6 and hit this problem: scsys.co.uk:8002/45223 02:11
that's with the june rakudo release btw 02:12
sorear cuppe: new is just an ordinary method
if you override new to be { say "constructor" }, then Player.new() will return whatever say() returns
object construction happens in the default new(), but you overrode the default new(), so no construction happened 02:13
any reason why you couldn't just use has @.hand = ... like you did for $.user? 02:14
ash_ cuppe: perlgeek.de/blog-en/perl-6/object-c...ation.html does a good job of explaining how object construction works in rakudo 02:15
cuppe sorear: because I want to do more than just assignment 02:16
ash_: ty
ash_ there are multiple parts of object construction, so adding a 'new' isn't always what you want
sorear cuppe: use BUILD, then 02:17
cuppe yeah. I didn't know about it, I tried new() and other stuff 02:18
now it prints "Any()" instead of the expected "6" 02:19
ash_ the image in the middle of the post is a great visual representation of the construction process
cuppe why do I get Any()? 02:22

sorear cuppe: Any is the default value of an uninitialized variable 02:56
I guess your BUILD is overwriting whatever sets up variables, or something
might play around with --target=pir to see what Rakudo's really doing; there's probably a bug report lurking in here somewhere 02:57
cuppe if BUILD works like that should that be expected behavior 02:58
ciphertext cuppe, sorear: i suspect this is a bug. The spec (S12:827) says that "any default attribute values are implicitly copied into any attributes that haven't otherwise been initialized"

mmcleric is this intentional?
moritz_ yes 09:15
(:foo) is a list/parcel of single pair
while :foo is a named argument in the context of a signature
mmcleric yes, i understand it
i'm asking because jnthn's suggestion to propagate all .returns() in Actions.pm broke things 09:16
handle_named_parameter relies on .returns() value to check node type 09:17
and with () around it, (:foo) returns Pair too now
moritz_ so it's probably missing a :named or so 09:18
09:18 plobsing left
mmcleric its missing .value 09:19
or do you mean i should check if node has :named attribute to check if its really pair and not pair in parens? 09:20

pmichaud segfault is a bug, yes. 12:17

it returns a failure
tadzik well, if I use say not die, CATCH works 12:18
but the program does not terminate even if I put exit in CATCH, prints some other things anyway
pmichaud ah, the segfault is because the CATCH is catching the 'die'
I think that's a known bug.
(at least, that's my guess)
at any rate, I don't think open() should be throwing an exception. Perhaps I'm mis-remembering the spec, though. 12:19

frew is it supposed to be possible to modify a grammar at runtime? if so, is that implemented in rakudo 16:07
TimToady sorear: it is intended that all function/macro defs be lexically scoped, and that a macro use the 'lift' statement prefix (NYI) to genericize its code into its caller's lexical scope 16:08
S04:768 16:09
I'm sure the spec still needs some work there though...
so if you ask me embarrassingly good questions about lift, I'll say "Beats me." :)
ingy frew: I will probably need to do that today as well...

frew very cool...
ash_ that lets you add more to it leter
later*
frew and presumably if I define a token in the second grammar that's already in the first it just blows the former token away 16:11
I wonder if it would be better to just make a sub grammar (isa) at runtime and override from there
probably.
ash_ TimToady: can you use a role on a grammar to add tokens? 16:12
TimToady ash_: STD already does that
pmichaud frew: inheritance is generally preferred to monkey patching :)
frew pmichaud: that's what I figured 16:13
ash_ cool, so you can do a role instead
frew I like it better to
too*
then you can go back
TimToady everywhere you see .tweak in STD, it's really doing a mixin of a role
ash_ or inheritance... lol so TMTOWTDI
TimToady mixins are inheritance, not monkey typing 16:14
ash_ monkey typing doesn't work on grammars?
pmichaud ash_: it *does* work, but it's not preferred :) 16:15

pmichaud mmmmm.... running spectests on amazone ec2 instances takes only ~20 mins :)

pmichaud: and then set up a pre-commit-hook 8-P
pmichaud afk, errands 16:21
frew so could I use a grammar role to add | 'x' to a token? 16:28
and can I do something similar in a subclassed grammar? 16:31
for example, instead of copying the parent token and adding | 'x' myself, could I do soething like, .next::token | 'x' ?
ash_ frew: have you seen proto regex's?
pmichaud frew: protoregexes
frew ash_: no; looking for examples now 16:32
pmichaud they're explicitly for "add a new alternative" to a token or regex

pmichaud token number:sym<0d> { '0d' \d+ }
token number:sym<0x> { '0x' <.xdigit>+ }
frew ok, so sym isn't like, a variable name then? It's what says this is a candidate? 16:34
pmichaud token number:sym<integer> { \d+ }
the above causes <number> to match any of the candidates
frew right
pmichaud if you use <sym> in a regex, it corresponds to the name of the regex
thus
token number:sym<0x> { <sym> <.xdigit>+ } # same as above 16:35
frew oooh
neat
pmichaud (it also captures to $<sym>)
anyway, you can subclass the grammar and add new token number:... regexes 16:36
frew right
pmichaud so then <number> in the grammar subclass includes the ones from the base class as well as the ones added in the subclass
frew and that sounds very clean and neat
pmichaud It is.
as an added bonus, protoregexes do some nice lookahead based on constant strings 16:37
16:37 masak joined
pmichaud so, when matching <number>, it's able to jump directly to the 0d or 0x rule if it sees that next in the match (and it doesn't bother calling those subrules if it doesn't) 16:37
masak hi, #perl6!
frew very cool
TimToady protoregexes are really a form of alternation, and full-blown P6 is supposed to write you a LTM matcher at every alternation
pmichaud correct
NQP is able to handle rule-level alternations at the moment 16:38
it doesn't do intra-rule LTM on alternations yet.
TimToady (which STD has a brand-new implementation of from sorear++)
pmichaud yes, I'm looking forward to stealing STD's new implementation, or adopting it altogether :)

pmichaud masak: quick question?
masak absolutely.
pmichaud I'm a bit curious about the signature of Buf.new()
it says it takes an array
not a slurpy array?
masak yes. 21:17
that's new.
I changed the spec and everything.
pmichaud why an array and not a slurpy, ooc?
masak this was after talking with jnthn, who indicated that a slurpy array would be very expensive here.
since we expect Bufs to be fairly long.
apparently making the array slurpy incurs a big speed hit. 21:18
pmichaud ....and we expect these long bufs to be created using .new ?
masak how else would you create a Buf?
pmichaud one could create an empty Buf and add things to it
ingy why would a build hang on 'src/rakudo/parrot_install/bin/parrot-nqp --target=pir --output=src/gen/perl6-actions.pir'
??
pmichaud (I'm just asking :)
ingy so frustrating... 21:19
pmichaud ingy: I'm guessing your machine might be a little short of ram?
masak pmichaud: it seemed like a good idea at the time. :) still does, I think.
pmichaud masak: okay. I'm not so sure that slurpies will take the huge speed hit in the future, though.
ingy is there a way to get a binary build?
pmichaud masak: and I'd hate to set an API based on Rakudo's current characteristics. 21:20
masak pmichaud: one thing I can think of which might change the decision back is if other similar constructors take slurpies, like Set.new, for example.
pmichaud afaik, Array.new and Seq.new all take slurpies
masak hm. ok.
pmichaud I don't know about Set.new
masak will discuss it with jnthn++ next time I see him.
pmichaud makes sense
masak g'night.
pmichaud but just because slurpies are slow now doesn't mean they'll always be that way :)
masak indeed. 21:21
21:21 masak left
pmichaud (and I'm not so sure they're slow now for basic arrays) 21:21
ingy: I'm not aware of any binary builds at the moment
(we certainly hope packagers will create some when R* comes out :-) 21:22
ingy pmichaud: Mem: 262364k total
pmichaud 256MB? That's a little small for Rakudo build, yes. 21:23
ingy it's a slicehost image :\
pmichaud I just tried some builds on Amazon's EC2 cloud system -- worked very nicely there :-) 21:24
even builds under the "small 32-bit image"
ingy pmichaud: what's the fast path to get set up there? 21:25
pmichaud but yes, 256MB is likely to be a bit constraining at the moment. We'd like to get Parrot and Rakudo to use less memory, but there's a fair bit of refactoring and optimization that needs to happen for that.
on ec2?
