PerlJam Ontolog: wrt p6c bitching and moaning ... So it appears the MMD is dispatching based on type first, then number of args? (i.e., you sent split(Str,Sub,Int) and it got dispatched to split(_,Str) instead of split(_,Str,Int) ) 05:04
er, ... instead of split(_,Sub,Int) 05:06
or something 05:07
Ontolog I sent split(String,Sub,Int) and split(String) got invoked instead of split(_,Sub) 05:10
but
when I sent split(String,Sub), split(_,Sub) gets invoked
spooky? yes
05:12 hercynium left
PerlJam right. It looks like the sorting algorithm for multiple dispatch puts entries with matching types first before those with matching parameter count (if it even looks at the number of parameters. I'm just assuming that it does) 05:13
Ontolog if that was the case, then split(String,Sub) should invoke split(String) and produce the error then, but it doesn't 05:14
05:15 xinming left
PerlJam well, maybe it's not the sorter but the matcher that's faulty 05:16
(yes, I'm clinging to the not-so-rational belief that the dispatcher is the problem and not something else :-) 05:17
Ontolog well parrot hasn't reached a 1.0 yet so it could very well be the dispatcher... 05:22
i'm not so familiar with it all to know
PerlJam Hmm. pdd27 says that those parameters that participate in multiple dispatch are marked with :invocant 05:24
I don't recall seeing that at all in the split() multis
05:24 xinming joined
PerlJam so, maybe they are all equally likely as far as the dispatcher is concerned wrt number of parameters, so it's only matching based on type. 05:25
of course ... the only place :invocant is mentioned is pdd27 and pirc and imcc. 05:26
(i.e. no other pir files use it)
05:29 justatheory left
PerlJam Ontolog: the haskeller in me wonders what happens if you move the split(String) multi to be defined after the split(_,Sub) multi 05:31
05:33 eternaleye left 05:37 xinming_ left 05:38 xinming_ joined 05:50 xinming left
PerlJam Ontolog: why is the multi for split(String) not really declared as split(String,String) I wonder? Seems like that would be best and may actually solve your problem. 05:51
enough random musing for me, it's time for bed.

slavik what is the accepted extension for perl6 code? is it pl? 14:08
ruoso slavik, file extension has no meaning most of the time... perl 6 modules will keep the extension .pm 14:09
slavik what should I use for source code though? 14:10
ruoso for perl modules, .pm for perl scripts usually no extension in the unix world.. but in the windows world you probably need to put .pl 14:11
slavik ruoso: I just want to be able to separate perl6 code from other code ... 14:12
in case I put it all in the same directory with shell scripts and such
ruoso that's not the role of the file name...
but you *can* use .pl in the end
if that helps you... 14:13
but in the unix world that is completely unnecessary...
slavik ruoso: I know
ruoso: people put .sh at the end of shell script filenames though :)
ruoso mostly they don't
just take a look of how many shell scripts you have in your /usr/bin without .sh in the name 14:14
the same for perl scripts
and for any other language, actually
slavik true, but we are people :) 14:15
ruoso I'm not sure I see your point...
slavik well, I got pugs installed, but no cool things to try out :( 14:23
ooh, does perl6 use bignum by default? 14:26

ruoso lambdabot seems a little delayed...
slavik hmm, looks like push @array is slower in perl6 :( 14:55
much slower 14:56
ruoso slavik, pugs is a prototype perl 6, it is supposed to be slower 14:57
slavik :(
but it's awesomer :)
no, it's not a word :)
PerlJam slavik: you mean slower in pugs. How fast is it in rakudo? 14:58
slavik I haven't tried rakudo
PerlJam (or any of the other perl6 implementations for that matter)
slavik isn't rakudo the parrot based one?
hmm, pugs does use less memory than perl5 in my case 14:59
PerlJam It seems a tad premature to be measuring memory consumption and execution speed (unless you're doing so explicitly to improve a particular implementation) 15:00
slavik I am just looking at it 15:01
for comparison's sake
15:01 rindolf left
PerlJam if an implementation is in flux (granted, pugs isn't very fluxy) then whatever numbers you get will be close to meaningless. 15:02
slavik PerlJam: it satisfies my curiosity :)
PerlJam If you compare all of the perl 6 implementations, it might be useful in a gross sort of way. 15:04

pmurias ruoso: we could implment gather/take with continuations 15:44

ruoso cool
15:44 pmurias left 15:45 pmurias joined
pmurias All tests successfull in smop withough ugly warnnings ;) 15:45
ruoso pmurias, yes... gather/take will be implemented using continuations... my doubt is how to implement the "take" part, not the "gather" part 15:46
:)
pmurias, take a look at test/35
it's beautiful :)
it shows that the evaluation of map and grep is streamlined from the input iterator
pmurias i'll look just got back home
ruoso which means "guaranteed lazyness" ;) 15:47
pmurias every time a gather needs to fetch an element it has to save to continuation somewhere, invoke the continuation used for generating the results and take will invoke the orginal continuation 15:48
ruoso but how do take find the gather? 15:49
do we just $interpreter.continuation.back.back.back untill we get to the gather? 15:50
pmurias maybe a stack of some sort? 15:51
it would have to be thread local 15:54
ruoso a global stack doesn't seem very likely... 15:56
but if you think that way, $interpreter.continuation.back.back.back is a stack
we just need a way to find out when we reached the gather 15:57
pmurias we need also some way to attach info to frames (we could also read a register... but it's a bit hackish) 15:58
ruoso pmurias, well... the "continuation API" is supposed to provide that kind of information 16:02
pmurias ruoso: isn't "local @Something::GATHER" enough
ruoso that's not very concurrency friendly 16:03
16:03 alanhaggai joined 16:07 eternaleye left
ruoso pmurias, it's important to realize that each thread will have its own interpreter instance, but the global namespace is still the same, and lexical scopes might point to the same outer... 16:07
pmurias ruoso: found it ;) we could use a contextual variable 16:08
ruoso heh... we
well
a context var simply means $continuation.back.back.back...
pmurias food& 16:09
ruoso then we still need to find out when that back is the gather
that problem is actually very similar to the problem on how "return" should work 16:11
since take is like a special kind of return
pmurias return throws a control exception 16:17

pmurias ruoso: take could throw a control exception and gather could catch and resume it but it would require implementing exceptions in smop 16:25
ruoso pmurias, maybe it's time to do it 16:29
16:29 Front_slash joined
pmurias ruoso: could be, we workaround the lack of exceptions already in some places 16:40
(in the unknown method at least)
ruoso but I mean... if "return" should be implemented in terms of exceptions... it's probably the time to implement it 16:43
pmurias yes 16:46
return and warn are implemented are meant to be implemented in terms of exceptions, but the compiler if free to optimise
ruoso alright then... let's start designing the exception model ... 16:47
what I have thought so far is having a "jail" property in the continuation, which, if defined, should decide if and how to handle the exception... 16:48
pmurias maybe CATCH or catch instead of jail? 16:51
ruoso: will we have a mold frame for every block? 16:52
ruoso maybe... 17:01
but we can't count on that...
but we almost certainly will have more than one frame for a routine
pmurias ruoso: Perl 6 has both a CONTROL and CATCH S04:788 17:02
ruoso: context() and exceptions seem to work at per block glanularity 17:03
inlined subroutines might not have a frame 17:04

ruoso pmurias, about the ri rsl, there's nothing specially bad about it, it's just because two of the types I created are not really conventional (they never have instances), and the other was a copy of another (grep was a copy of map) 19:10
pmurias, for some reason I think that setting NULL in pointers after the region it is pointing was freed is a good practice... but I don't have any concrete information to support that idea... 19:13
pmurias what do you think for having GET(foo) and SET(foo,...) for locked setting and getting the fields in RI's 19:24
