japhb jnthn: is it possible to set sub params as rw in Rakudo, and have it work? 00:19
jnthn Yes.
Though it's on my list of things that may not have good spectest coverage
japhb k
just sub foo($param is rw)? 00:20
jnthn But I did review this just a few days back when pm and I were doing the container refactors.
Yes.
japhb cool beans, thx
jnthn rakudo: sub foo($x is rw) { $x = 42 }; my $a = 2; foo($a); say $a;
p6eval rakudo 32502: OUTPUT[42␤]
jnthn Yes, works.
wayland76 Are there any windowing toolkits that cat be used from Parrot yet? 00:26
s/cat/can/
jnthn wayland76: I know there's SDL but I don't know that this counts as windowing toolkit. 00:28
japhb wayland76: and there's GLUT. Same problem.
Although it does create windows and menus ... :-P 00:29
wayland76 Well, maybe SDL will do what I want :)
jnthn doesn't know much about it 00:30
wayland76 At the moment, I'm mainly after something that makes canvases easy :)
Anyway, now that I know what the options are, I can investigate them :)
Thanks :) 00:31
jnthn Welcome, have fun. :)

TimToady what the heck was that? 00:55
why did it include foo:?
it should have been parsed as a label
jnthn TimToady: What?
Labels inside double quotes? 00:56
TimToady ah
missed those
jnthn breathes a sigh of relief
TimToady I misread a question on my SAT like that too--kept me from getting an 800 on the math section...
jnthn TimToady: Am I right in thinking that if you declare a class, then write a BEGIN block after it, you can use that class, instantiate it etc in the BEGIN block? 00:59
TimToady yes, declarations happen at compile time
jnthn OK. 01:00
TimToady otherwise there wouldn't be much point in 'em
jnthn OK, that was the answer that I was expecting.
Follow up.
my $x is foo; # where foo is some trait we've defined
If we have that inside a sub, we would apply the trait each time the sub is invoked? 01:01
As in, create a container and apply the trait?
Or is that somehow a one-shot thing at compile time too?
TimToady there's an abstract $x that is shared by all invocations...at least in the abstract :) 01:02
ruoso meaning that the runtime can clone in each passage?
s/passage/invocation/ 01:03
TimToady it seems like you'd want to factor out common operations to one spot though, to the extent that your VM allows it
jnthn OK, so if the trait kept track of how many times it was applied (or, OK, the trait_auxilliary:is multi for that trait did), and we only ever wrote "my $x is foo" once in a subroutine, then called that sub 100 times, the counter would only get incremented once? 01:04
TimToady but if a VM cannot support something declaratively then it has to be emulated, of course
jnthn hopes his question made sense - I can put it in code too if not!
Limbic_Region TimToady - the SATs were restructured in 2005. I scored a 1200 my sophmore year and never took them again
TimToady the trait is applied at compile time, in the abstract, not at run time 01:05
ruoso TimToady, on another issue, would you consider who's job to move bare statements in a package to INIT? viv? STD? or the actual compiler?
jnthn TimToady: OK, thanks. I'll probably now spend my flight on Thursday working out exactly what the fallout of this is. :-) 01:06
TimToady ruoso: I don't really understand your question 01:07
ruoso TimToady, viv currently sees the list of statements as plain 01:08
independently if it is a method_def or something else
TimToady well, it's certainly not peanut
ruoso it's my understanding that method_def, as well as other declarations happen at BEGIN 01:09
and other statements are only executed at INIT
TimToady after INIT, but go on
ruoso who do you think is the responsible for sorting out what should be in BEGIN and what shouldn't? 01:10
STD?
viv?
or the compiler itself?
TimToady I guess I don't know what you mean by "the compiler itself" 01:11
ruoso well... in our current setup...
mildew
diakopter out of band call to #perl6?
TimToady and I don't why you mention viv, when that's the vi-to-v translator :)
jnthn suddenly gets what viv stands for 01:12
TimToady anyway, every construct needs to know whether it executes itself as part of its own reduction
and declarations may or may not return extra stuff to run at run time 01:13
my $x = 42; still hast to do the = at run time
but it doesn't have to do the "my" part, except insofar as the variable storage needs setting up at entry
01:14 hercynium joined
ruoso ok... 01:14
in mildew we have...
STD -> viv -> mildew -> m0ld
TimToady it was intended that viv be copied, not used :) 01:15
ruoso I'm not sure at which extent it is "used"...
but wasn't viv the one that turned the match tree into something more AST-like? 01:16
TimToady I suspect it's just the callback engine, which is pretty small
sure, but that's like one routine, and you don't want the rest of viv
if we want to abstract out that routine, fine
anyway, not what you're asking about 01:17
ruoso right... but it doesn't really matter to the question...
jnthn TimToady: You write "except insofar as the variable storage needs setting up at entry" - if you're doing a trait like is dim(2,3,4) or something, then this sized/shaped array needs creating at entry.
TimToady: Does this mean that really the trait should be supply the AST to Do That at runtime?
And it gets shoved into what we compile?
Rather than the trait being invoked at runtime to do that... 01:18
...which I guess doesn't fit with what you said earlier. :-)
TimToady well, declarations can have all kinds of consequences, and certainly some of the consequences are at run time
jnthn Sure.
I'm just trying to work out how traits will look
I mean, in Rakudo we identify a bunch of them hard coded in the actions. 01:19
But, well, I don't think that's really what we want.
01:19 Lorn left
ruoso trying to put in an example... 01:19
class Foo { say 1; method bar {...} say 2; };
mildew currently sees the three statements in a flat list
TimToady well, assuming a newline in there 01:20
ruoso yes yes
but "method bar {...}" declaration will get executed much sooner than "say 1" and "say 2" 01:21
TimToady yes, in the sense that the method bar declaration executes even before say 2 is parsed
jnthn Wow. 01:22
That's even earlier than I expected.
ruoso who is the one who decides which statements are executed when?
TimToady the reduction of a BEGIN block must trigger its execution
just generalize from there
ruoso but who defines which one is a BEGIN and which isn't? 01:23
TimToady there needs to be a method to run a block that is accessible to the reduction action
alternately, some way for such reductions to signal their surrounding scope to execute them immediately 01:24
ruoso so, STD has a hook for everything, and the runtime then decides what should be BEGIN and what shouldn't... 01:25
ruoso really looking at concrete code right now 01:26
not thinking abstract at all
TimToady another way of looking at it is that FOO {...} routines install themselves into various queues, and different queues are executed at different times
ruoso doesn't really understand what that means relating to the question 01:27
TimToady declarations just happen to have an abstract container object that can be modified when such a beginnish routine is called by a trait
ruoso right... but who puts the container? 01:28
STD?
TimToady different declarators create different containers
diakopter TimToady: may a BEGIN block redefine the parsing of a BEGIN block [including itself]?
TimToady STD is just syntax, until you add actions 01:29
ruoso mhmm...
diakopter I mean, it couldn't define away the BEGIN's }, could it
TimToady diakopter: no, it's already parsed
the BEGIN reduction doesn't happen till after the } is parsed
diakopter oh
ruoso feels too asleep to figure out entirely what all that means...
ruoso sleep & 01:30
01:30 japhb left
TimToady nite 01:30
jnthn TimToady: While we're on the evil... :-)
class Foo { method x { }; BEGIN { Foo.x }; }
Would we expect that to actually invoke x, or is it too early to instantiate Foo before it's definition is over? 01:31
diakopter jnthn: those noops are detected and eliminated :P
(kidding) 01:32
TimToady I think that's probably too early--it knows the name, but not the implementation 01:33
jnthn OK, sounds good.
TimToady so it would compile the BEGIN fine, but fail in the dispatch to Foo 01:34

..grammar rules. This switches around the ordering. Also re-fixes the bug originally fixed before this change where $?NS wasn't cleared.

jnthn a**{2...} maybe? 16:14
erm, a**2...
...maybe... :-)
masak doesn't currently work, anyway.
jnthn Whether it's allowed and whether it's implemented may be two different things mind.
masak ya. 16:15
jnthn I think it's what you'd want in the long run.
Could always file a ticket asking for it. :-)
PerlJam three dots == infinity? I thought you had to put a whatever-* there
a**2..*
(or something)
jnthn Oh, maybe
I forget exactly.
PerlJam me too :)
jnthn There is some infinite range style syntax that does that kinda thingy anyway. 16:16

and it works!

jnthn I think that you'd be able to make postcircumfix:<( )> take things into a capture, though.
pmichaud oh, I see the issu
issue
jnthn pmurias: We don't explicitly construct a capture right now.
pmichaud the strings that come back from PGE aren't Perl6Str
jnthn Ah. 16:44
pmichaud so it's calling the .trans method in (Parrot) String instead of (Perl 6) Str
jnthn The Parrot string has a trans method?
jnthn didn't know that
Makes sense though.
pmichaud METHOD trans(STRING *src, PMC *table) {
masak pmichaud: is it easy to fix? 16:45
pmichaud masak: not at the moment.
jnthn Needs HLL. :-( 16:46
pmichaud we need to get HLL type mapping in place.
masak oh well.
pmichaud and then PGE will have to become smart enough to do that mapping.
jnthn pmichaud: I forgot what that blocked on? Or is it just tuits?
masak will try to work around it somehow
pmichaud tuits, I think
masak: try prefix:<~>
masak pmichaud: I will, thx 16:47

pmurias jnthn: postcircumfix:<( )> takes a capture in smop and spec currently 16:47

pmichaud we may need to fix prefix:<~> to always return Perl6Str
(won't be necessary after HLL mapping, though.) 16:48
jnthn pmurias: Sure, that makes sense.
japhb jnthn: oh bother (re: packed data and (Un)ManagedStruct difficulties) ... that's going to make life ... interesting. Hmmm, is there a Perl 6 pack()/unpack() pair yet? I could go from that angle.
jnthn No, I think not. 16:49
pmichaud we can certainly write a pack()/unpack() or other helper function for it. 16:50

r32548 | pmichaud++ | [rakudo]: fix trailing space
jnthn looks at what doing the managedstruct stuff the real way from Perl 6 would take. 16:51
Ouch. 16:52
japhb: Actually implemetning what's under the heading Compact Structs in S09 is a bit of work. 16:53
There's a bunch of stufff I've not really thought about so much yet. 16:54
japhb jnthn: I believe it.
pmichaud: how much work would it be to do the pack()/unpack()?
pmichaud japhb: I don't know how well pack/unpack are defined for Perl 6 yet (more)
pmurias jnthn: it was a thing we were unsure about for a bit, and i was having doubts again for a moment about it while implementing .() ;) 16:55
16:55 pmurias left
pmichaud japhb: however, in this particular case you might look at writing a custom pair of functions to do it and importing those 16:55
japhb: I'm not completely familiar with ManagedStruct under Parrot (nevr had a use or need for it)
jnthn pmichaud: It lets you construct a C-level struct, dynamically. 16:56
16:56 alester joined
japhb OR array, or combination of the two 16:56
pmichaud jnthn: sure, I've just never used it.
jnthn It'll probably be somewhat involved when we do compact structs in Rakudo.
Really we don't have any of the native types exposed at Rakudo level at all yet though. 16:57
japhb It basically shows a normal keyed interface as if it wasn't packed, but marshals magically through NCI to/from the packed equivalents.
jnthn Which is really a pre-req.
japhb Parrot will need to finally admit its native type system is lacking when you have to do the Perl version. Unless you just tell Parrot it's a buffer of bytes and back the heck off, thankyouverymuch. 16:58

japhb jnthn, pmichaud: Is there a way to specify constants in a separate module in Rakudo, and after 'use FooConstants;' have them participate in any optimizations that literal constants would have? 18:04
18:05 abra left
japhb jnthn: what signature are you planning for the simplified MAIN? 18:09
jnthn japhb: Not that I know of - we don't have "is constat" implemented yet, either, though... 18:12
japhb Fair enough.
TimToady there is no "is constant" that I know of... 18:13
jnthn Simplified MAIN will just pass the command line args along. If you've written a MAIN that takes that many positional arguments, you'll get that one (of course declare multi if you're doing that to write many)
TimToady there's a constant declarator though
jnthn That's all I'm doing for now - this is really Jerry's turf. :-)
japhb TimToady: Either you read everything that goes by here, or you've got a very fine sixth sense ....
TimToady the two are not mutually exclusive :) 18:14
japhb True.
But I meant that in the math 'or' sense, not the English bastardization.
PerlJam TimToady: Tell the truth. You didn't really get *ordinary* corneas, did you? You're really a cyborg now. 18:15
TimToady will that MAIN break badly when named args get mapped to *% params?
japhb jnthn: So if I want to ignore all, can I declare 'sub MAIN { ... }', and to catch all just do 'sub MAIN (*@args) {...}'
TimToady I don't know who my (one) cornea came from, but both my lenses are plastic, though different from each other 18:16
jnthn Yes, that should work, apart from slurpy may be broken at the moment.
TimToady with slightly different transmission of near UV
japhb jnthn: oh.
TimToady so my black lights look violeter in one eye than the other
japhb Will @*ARGS still be visible, at least, if slurpy args are broken?
jnthn japhb: Yes.
japhb TimToady: freaky. and cool.
PerlJam TimToady: ah ... only one cornea, eh? So the other eye has the device that links you directly to the internet? :) 18:17
japhb jnthn: great, thanks.
jnthn TimToady: It's not meeting the spec for sure. :-)
TimToady maybe it should be called NOTMAIN or something :)
jnthn TimToady: particle's grant covers doing that, I'm just getting japhb something simple to work with for now.
japhb Somebody is getting paid well to make it correct ....
jnthn Right.
