skids perl5 embedded in pugs -- any way to get functions that modify parameters to work? 01:57
e.g. IO::Socket::INET::recv($dat,1,0) modifies $dat, but it is not modified from perl6 01:58
allbery_b you have to do something special to get variables propagated, IIRC, but I don't' recall what. (and it may not be implemented yet, even; I foret) 02:00

Tene So, question about method delegation. 07:49
S12 says "has $the_real_me handles *;"
07:50 mattz joined
Tene Is there any corresponding way to specify a function that gets called when no other function defined on the object matches? 07:50
I think ruby calls it method_missing or some such. 07:52
That seems like the sort of thing that should be possible in Perl 6's meta-model, but I can't find anything in the spec about it.
japhb_ Tene: I vaguely recall something like "AUTOMETHOD", though that's probably ancient spec-wise 07:56
Aankhen`` I coulda sworn there was an "AUTOMETHDEF" or something like that, but I can't find it in the spec. 07:57
Okay, from <perlcabal.org/syn/S13.html#Fallbacks>: "If an attempt is made to dispatch to a declared but undefined routine, Perl will redispatch to an AUTODEF submethod [conjectural] as appropriate to define the routine." 07:59
I guess it's not fleshed out yet.

rhr TimToady: what's the default normalization form for Str.print, .normalize, .codes, and .ord? should any of them fail by default? 18:40

TimToady print should know what its handle wants. 19:08
I'm not sure .normalize is useful under graphemes
.ord/.chr should probably be based on grapheme id normally, so NFC 19:09
19:10 tobeya joined
TimToady if "use codepoints" declares whether the default is nfc or nfd, maybe .normalize defaults to that 19:11
(in that lexical scope)
and maybe under use bytes you also get a default encoding, so .normalize.encode can take any Str and turn it into, say, :nf<d> :enc<utf-8> 19:13
so maybe the defaults in Functions.pod are wrong, and should default to something in the lexical scope 19:14
like $?NF and $?ENC
I suppose open could also default to $?NF and $?ENC
or maybe we don't tie it to "use bytes" and "use codepoints", but have "use nf 'c'" and "use enc 'utf-16le'" instead, since you also might want $?NF and $?ENC to default for other things like converting Str to Buf 19:18
even under the grapheme view
hmm, maybe it's just "constant $?NF = 'C'" in that case, and no use is required
19:20 masak left
TimToady but if the other arguments are :nf<> and :enc<>, then maybe "use uni :nf<kc> :enc<utf-32>" is what people would prefer to write to set their defaults 19:20
for consistency
19:21 stevan_ left, stevan_ joined
ruoso TimToady, is it ok for a specific environment to declare new $?FOO variables? 19:23
I mean... smop will probably have a $?STACK
TimToady why not? 19:24
except that would imply that $?STACK is a compile-time constant
ruoso I mean, I was just wondering if that was not something to be specced
TimToady which I kinda doubt
ruoso $?STACK is kinda a compile-time constant that means, the current stack on that block
the value is not constant, but the meaning is 19:25
TimToady as soon as you say "current" it's not a constant
no, that's why we got rid of $?SELF
alester afternoon all
TimToady if it varies, you can use $*STACK
ruoso but then it means it can be local
and it's not the case
better yet, 19:26
TimToady maybe we need a dynamic sigil...
*twigil
ruoso the "current" stack only means something inside a block
like sial.org/pbot/29849
lambdabot Title: Paste #29849 from "ruoso" at 195.23.61.1
ruoso it should probably be a macro, actually
TimToady like "self" really 19:27
ruoso but, should I use a plain bareword?
TimToady __STACK__ if we reserve those for implementation details
rhr doesn't $+ kind of do that?
ruoso __STACK__ seems fine to me...
weird enough to not cause any confusion 19:28
TimToady $+ scans for a contextual variable
ruoso I think the point is to get a pattern for this implementation-dependant macros
TimToady rhr: did you see my unicode microrant above?
ruoso I mean... HOW is available in all implementations, but __STACK__ isn't 19:29
rhr yes, thanks
ruoso I should probably follow the same pattern to RI
__RI__(obj)
or obj.__RI__
rhr I was thinking .normalize would be used to tell a graph Str how to become a codepoint Str when asked, is there another way to do that?
ruoso because it's only available in some Perl 6 implementations
TimToady shades of python...
I think it is probably not useful for a Str to know how to become a codepoint without knowing how it's going to be used 19:30
it's the context that uses it that knows how it wants it 19:31
and two contexts could want it differently
you pass a Str into a module, and it's written in "use codepoint; use :nf<c>"; and then it sends it to a random handle which is set to :nf<d> 19:32
ruoso will consider the __FOO__ pattern for implementation-exclusive-macros from now on..
19:32 rindolf left
TimToady at each of those context switches it should do the right thing 19:32
rhr OK, that sounds good 19:33
TimToady note that you might have some trouble if you link in a python program and call $obj.__STACK__
if you think it's a macro
but python thinks it's an ordinary method
maybe we should go with something newish 19:34
maybe ___STACK___
ruoso hmm... should I stick with __STACK__() only?
I mean
__FOO__() only
__STACK__ doesn't get any parameter
or __RI__(__STACK__) 19:35
to get the responder interface of the current stack
TimToady that would always dispatch mmd-wise so would stay in the Perl universe
it's only the $obj.foo form that can interpret "foo" according to the language of $obj
but I'd say just for avoiding cultural confusion to use triple underscore
and since it's going to generally be hidden from the user 19:36
and implementation vars are going to be fairly rare
so longer is okay
ruoso yeah... that is for very deep things, like implementing CPS in core
probably some module will hide it away
TimToady maybe for continuations we can use 52 underscores :)
ruoso heh 19:37
I mean, did you see the code snippet in the paste?
that's how to implement CPS in SMOP... :)
