Guest2304 For the fizzbuzz code (github.com/Keith-S-Thompson/fizzbu...buzz.pl6), I switched the guillemets to <<~>> and Rakudo said No such method 'postcircumfix:<( )>' for invocant of type 'Parcel' 11:00
11:00 Guest2304 is now known as Ovidius, Ovidius is now known as Ovid, Ovid is now known as curtispoe
curtispoe Bah. 11:01
phenny curtispoe: 18 Feb 00:48Z <[Coke]> ask curtispoe if github.com/Ovid/Config-Tiny is gone or moved.
curtispoe phenny: tell coke That he's probably looking at my old github.com/Ovid/Config-INI work? It's really sloppy and out-of-date. 11:02
phenny curtispoe: I'll pass that on when coke is around.

jnthn hm...
curtispoe Also, is that leading [~] somewhat superfluous in that code?
jnthn The code should never have worked with the «~» form, it seems. Wonder how we missed that postcircumfix... 11:07
yes, that looks like a misunderstanding wrt the [~]
The method call binds tighter
It looks like it's doing the right thing anyway (print on a list seems to work the right way) 11:08

Actually, I think a join would probably be better than the hyperoperator there. More clear?
jnthn yeah, but it feels like it's using a hyperop for no reason at all 11:11

arnsholt jnthn: Anyways, that gist has some multidispatch oddness. Looks like constants interact oddly with multidispatch. Is that a known issue? 11:15
jnthn I guess constants are packaged scoped, and packages don't really do native types given it's just a hash 11:16
arnsholt Ah, right. That'll explain it, probably
jnthn And if we "fix" multi-dispatch to let you pass boxed things where native types are expected we get other nasty problems.
arnsholt Sure, sure 11:17
jnthn oh...
I wonder if we can handle it as a failover
Though "can I make it work by trying harder" solutions can be a bit too magical.
The problem is basically that if we have an int candidate and an Int candidate, we'd like the Int one to win on a boxed object. However, native types always sort more narrow. This means that the native candidate needs to reject being passed a boxed object, otherwise it'd always hide the Int one. 11:20
arnsholt Right, right 11:22
But a non-multi will silently unbox an Int to int, no?
jnthn Yeah. 11:23
That discrepancy does make me unhappy.
arnsholt Excellent. Then I think I can just remove the int type constraint (it's not useful to multidispatch anyways)
jnthn The reason it can Just Work (for some definition...) is that there's no ambiguity over what to call. 11:24
arnsholt Yeah, it makes sense
jnthn wonders if TimToady++ will have any insights when he backlogs over this :)
arnsholt Let's hope so =) 11:26

not_gerd o/ 11:31
jnthn: is there some repr/MOP magic that makes it possible to do type punning (in particular int64 -> num)? 11:32
jnthn not_gerd: Don't think there's anywhere that happens. It's...kinda evil to do, since I guess it's rather platform specific what happens. 11:35
You could potentially write a REPR that had a union underneath.
So that it'd support nqp::unbox_n(nqp::box_i(42, MyTypeWithMagicalREPR)) 11:36
But we don't provide one that does that. 11:37
not_gerd it's probably easier then to just use nativecall

Does C even have a name for those?
not_gerd jnthn: no, it doesn't
some graphics cards come with hardware implementations, but your CPU/FPU normally doesn't 11:40
I just want to use them as a serialization target, so that's not a problem
11:41 cibs left
not_gerd I just need to construct a double from a uint16, and for that I need to fiddle with a uint64 that needs to get punned to said double 11:41
11:43 cibs joined
jnthn I wonder if you can do it with a buf and pack/unpack 11:44
not_gerd doesn't look like (un)pack supports floating point yet 11:49
I could construct the values using arithmetic operations instead of bit fiddling 12:10
will be pretty inefficient, but well..

PerlJam uvtc: wordpress groks HTML easily enough. 14:12
(I think that's even it's internal storage format)
moritz yes, HTML with some caveats 14:13
for example each paragraph should be a single line
otherwise wordpress "helpfully" inserts <br /> tags for you, even if you enter it in the "HTML" view

uvtc moritz: An easy way to deal with the announcements is to write them in markdown, then use `pandoc` to convert to html for copy/paste into the blog. 14:14

uvtc moritz: I can make a 2013.03 (or a template) from the 2013.02 and tweak it to be markdown-formatted, if you like. 14:15
moritz uvtc: that would be nice, yes
then github could also show the announcements directly
uvtc Well, github would need a .md filename extension in order to do that. 14:16
Is this in the rakudo/rakudo repo, or the rakudo/star repo, or both?
moritz both 14:17
PerlJam or write them in pod and use pod2html

uvtc When I build R*, why does it put a copy of the `install/bin/perl6` binary right there in the top-level rakudo-star directory? Users are going to be adding the install/bin to their PATH anyway (if they wish to use `panda`)... 15:44
So having that extra copy appears redundant.
15:44 SunilJoshi joined
FROGGS uvtc: the one in the top level is created when doing `make`, after that `make install` copies all the files to the install location, which is right now a subfolder within the repository 15:50
this might change so it will install to /usr/local or to to /opt in future 15:51
uvtc FROGGS: Thanks. Yes, I see that it's a copy of the one in install/bin.
FROGGS but it is always sane to add the install folder to $PATH, ya
uvtc FROGGS: Oh, I very much like that Rakudo installs into its own local "install" directory.
FROGGS no, the one in install/bin is the copy :o)
put that's not the point of `make install`, at least not for me 15:52
uvtc FROGGS: the reason I ask is: users are going to put "path/to/rakudo-star/install/bin" on their path anyway (to access panda and p6doc, at least). So the existence of that top-level `perl6` binary seemed redundant. 15:54
sergot Where can I find a really really good article about Perl 6 Grammars? 15:55
15:57 lichtkind joined
FROGGS uvtc: so the top level binary might be better in a _build directory, is that what you propose? 15:57
15:57 SunilJoshi left
FROGGS sergot: I can't if it is really really good, but maybe this: perl6advent.wordpress.com/2009/12/2...d-actions/ 15:58

sergot: and the book, chapter 10: cloud.github.com/downloads/perl6/bo....23.a4.pdf 15:59
uvtc FROGGS: having it at the top-level suggests to users to but "path/to/rakudo-star" on their path, rather than "path/to/rakudo-star/install/bin".
FROGGS uvtc: it does, ya :/
sergot FROGGS++ thanks 16:01

TimToady is there any way to load a dynamic library from the rakudo level yet? it's not obvious to me that there is... 16:33
jnthn TimToady: use NativeCall ?
TimToady: Or did you mean something else? 16:34
TimToady load a .so or .dll
uvtc holy moly. If that isn't shouting, I don't know what is. :)
jnthn Well, NativeCall loads those, looks up a symbol and gives you a way to call it.
16:35 daxim left
jnthn That's what DBIish does for its database drivers, for example 16:36
TimToady there isn't much pod in NativeCall.pm6... 16:37
jnthn README has a bunch of docs, though 16:38
TimToady oh, zavolaj, not NativeCall 16:41
jnthn star: use NativeCall; sub dlsym(Str $lib, int $flags) returns OpaquePointer is native { * }; my $x = dlsym('libreadline', 0); say $x
p6eval star 2012.12: OUTPUT«(signal SEGV)»
jnthn hm :)
wonder what the sig of dlsym is meant to be. :)
TimToady: The module is called NativeCall. The repo is zavolaj for...historical reasons. 16:42
There may be an argument for pulling the module into core these days.
TimToady what's the name of the module called? :P
jnthn "A module name" :P 16:43
TimToady anyhoo, thanks
jnthn All the guts of it are actually provided at VM level 16:44
TimToady what's a NativeCall on JVM?
TimToady is quibbling with the term "native" here...
jnthn There's JNI (Java Native Interface).
TimToady so NativeCall really means C_Call or some such
jnthn JNI also means "Native" in the dll/so sense. 16:45
16:45 brrt joined
TimToady would be nice to be able to use the same API everywhere 16:45
uvtc natives are getting restless...
jnthn Provided the appropriate REPRs and ops can be implemented in terms of JNI, I think we should be able to have NativeCall work the same way.
TimToady can NativeCall wrap JNI?
jnthn That's the goal. :) 16:46
Just needs some of arnsholt++, myself or somebody else to have the tuits to attack it :)
TimToady not bugging you, just askin' 16:47
jnthn didn't feel bugged :)
TimToady I know you have a think or two else to do first :)
jnthn Yeah, but it's also one of those things that won't want to wait too long.
I really don't want the JVM port to get a label of "doesn't let you use a load of the ecosystem due to no NativeCall support" 16:48
TimToady agree that NativeCall should be a battery included
hoelzro NativeCall is (to me) one of the coolest things about Perl 6
(even though it's currently specific to Rakudo) 16:49
jnthn I'd hope its API is possible to provide by other impls, though. Provided they have *a* NativeCall that matches the API, libraries that depend on it should be usable.
I expect the exact way NativeCall is written to vary a bit. 16:50
But it's a much better story than dozens of modules doing implementation-specific things to do native calls. 16:51
TimToady just need to watch out for gratuitous differences, I suppose
nwc10 apologies for the ASCIIfied nature of the following 16:53
TimToady but happily, if we don't get it quite right, someone will just slap an abstraction layer over it all :)
nwc10 so Vienna's marketing slogan is "Wien is anders" (Vienna is different)
TimToady ist?
nwc10 is Perl 6 different? Or at least, is Rakudo different? In that, of all the dynamic languages I can think of, is Rakudo the only implementation that intends to target multiple backends? 16:54
TimToady: yes, sorry ist
I can't type. I blame my fingers
jnthn That ist a good question...
nwc10 in that there's the original and the best, and Jython, and IronPython
TimToady you mean, as opposed to having multiple implementations on different VMs? 16:55
nwc10 yes.
exactly that
as best I'm aware, all the others are "different VM implies different implementation codebase"
TimToady I'm sure some of the implementations would like to take over the world that way
I think PyPy had some pretentions of replacing CPython at one point 16:56
nwc10 did they stop? :-) 16:57
I've stumbled across some curious Python heresy recently.
TimToady I think a certain Guido put his foot down on that subject
nwc10 aha.
TimToady but that was several years ago
things coulda changed since then
nwc10 He didn't purge the thoughtcrime at the bottom of this page: mercurial.808500.n3.nabble.com/Merc...19707.html
(mercurial's ticket on "no, we're not really going to port to Python 3 any time soon) 16:58
there's similar thoughtcrime on Trac's equivalent ticket: trac.edgewall.org/ticket/10083
anyway, that's a digression
TimToady
.oO(no observable demand)
jnthn nwc10: I think Rakudo's approach is different in the sense that we're saying "well, Perl 6 wants to be on many VMs anyway so let's just build an implementation that can go there" rather than "let's built for one VM and folks can start over for others" 16:59
Rakudo isn't the only Perl 6 implementation, of course.
nwc10 jnthn: which, longer term, seems a more efficient approach.
TimToady and we're still in a state that we can bend the original definition of the language to make cross-platform stuff work better 17:00
jnthn nwc10: Yes, with the caveat that you have to design smart enough to let the ports be efficient.

nwc10 yes, and I'm aware of some of the history of Perl 6 implementations. But right now, it's looking like the only one that's going to be mostly feature complete when the spec and the testsuite "hit" 6.0.0 17:00
so there's sort of this risk of "the implementation is the spec". But not *terrible*, as being on multiple VMs already avoids a lot of the pain of Perl 5 17:01
jnthn For example, if there was no way for the JVM port to store stuff using normal JVM objects (which it does) or to use invokedynamic (which I mostly know how to do for a bunch of places), it'd be in a tough place. 17:02
nwc10 jnthn: efficient - to avoid the "We run on both VMs - .NET and JVM" ? :-)
TimToady well, any code that depends on unspecced behavior could be viewed as potentially producing flying butt monkeys
nwc10 (digression - I thought that JRuby managed to be pretty performant even on Java (1.)6?)
TimToady: are they more painful than nasal daemons?
jnthn nwc10: To get the best out of those two wants different things these days. 17:03
TimToady doesn't know
nwc10 is glad to hear this
given "where there's muck there's brass", I'll stick to the monkeys.
uvtc Possibly interesting datapoint: Clojure takes the approach of "implementations are symbiotic with the host platform". Meaning, Clojure-JVM may behave slightly different that Clojurescript, but they're the same language at heart. 17:05

uvtc But each impl meshes nicely with its host platform. 17:05

TimToady it's nice if there are gates labelled Here Be Dragons though 17:06

uvtc One tradeoff with that, though, is: "this module only works with $impl" 17:07

TimToady use Win32;
but yeah, perl has never been a procrustean bed when it comes to portability; some things just don't work everywhere 17:08
but that's no reason not to provide the functionality on a system that can support it 17:09

TimToady according to how S05 is currently written, <:foo> is only for Unicode properties, and the old Unix-ish character classes are written <+print> and such 18:19
so niecza looks righter here
I'm kinda inclined to leave it that way, since we have control over the method namespace, but we don't have control over the UCD namespace 18:20
so probably <.print> ought to work as well, since <+print> is (I presume) implemented as a print method 18:21
18:21 domidumont left
TimToady the other way would be to name mangle the <+print> into <.cclass-print> or some such, but not sure that buys us much 18:21
and there's something to be said for hiding the normal .print method, as yousay 18:22
and anyway, we've already kinda decided that any matcher can be used as a character class as long as it behaves well enough 18:23

timotimo: just noticed i didn't sudo the configure / make. would that be a problem?
moritz no 20:21
raiph moritz: thanks
moritz the default prefix is ./install, for which you usually don't need root privs
uvtc raiph: no, with R* everything happens right in your Rakudo distribution directory.
timotimo oh, right, they are bundled 20:24
that makes sense indeed

uvtc Is there any reason to prefer heredocs for multi-line strings, rather than just writing them out (including returns) with quote marks around them?
Oh, I remember one benefit (actually, I think TimToady told has mentioned it here): heredocs allow you to close up your function call or whatever syntax, while letting the multi-line string itself not visually clog up the parts that matter. 22:31
22:33 PacoAir left
jnthn That. Also they will remove indentation for you in Perl 6 22:33
so you can indent them to the same level of your code

bbkr I'm playing with NativeCall and GeoIP databases, CStruct return values work like a charm :) 22:48
jnthn nice :)
bbkr I'm not sure how to write union in struct (my C skills are rusty). if I have struct { union { int x; int y;} } should I declare both has $.x and $.y ? 22:51
jnthn No, 'cus there's only really one memory location... 22:52
The union elements share the space.
FROGGS[mobile] jnthn: btw, I'm tracking down the /<[abc]-[\wa]>/ issue, a bit more is fixed locally but still some weird results left
jnthn That's...not very easy to deal with at the moment in NativeCall...
FROGGS[mobile] jnthn: would you be able to have a look at a diff tomorrow? 22:53
bbkr does the name $.x/$.y matter or is struct unpacked using member sizes and denied order? 22:54
defined*
jnthn bbkr: The names are unimportant.
FROGGS[mobile] sizes only
jnthn bbkr: It's all about memory layout.
22:54 xenoterracide left
FROGGS[mobile] ya, so sizes and order 22:54
jnthn FROGGS[mobile]: Probably...though that bit of the code is a bit hairy... 22:55

Anyway, pass me a gist or something and I'll look when I can.

jnthn can't help but think that right now the best bet would be to take a step back, look at the problem afresh and then try a clean implementation of that chunk of the code... 23:40
Or at least re-consider the overall structure of it. 23:42
diakopter ya-know. An incredibly interesting feature could be for a special mode of the debugger to be that it inserts printfs all over the place *for you* automatically, perhaps filtered by type of activity "result of store/fetch" "return result of call", "arg value", etc. 23:43
er, s/printfs/says/
benabik Watchpoints?
Although I guess arg/return is normally done with breaks. 23:44
diakopter right, but automatic
jnthn Should be doable. 23:45
diakopter (inspired by that gist)
jnthn The debugger gets to diddle with the QAST tree and hook whatever it wishes.
I would point out that the more such things you add, the more noticably slower things get. 23:46
But after seeing how much tracepoints in visual studio can slow down program execution, I don't worry about that too much ;)
diakopter .add_watchpoint($yourmom) 23:47
23:48 skids joined
diakopter another option is to provide debug output statements that are conditionally compiled only by the debugger or something like that 23:49
(manually written)
(so the non-debugger compiler would no-op them)
or, dependent on a flag or dynamic variable or ENV or whatever, 'cept the flag is compile-time 23:50
TimToady welcome to #perl6
jnthn will have to have another round of debugger hacking at some point 23:52
There's loads more cool stuff to be done there :)
diakopter o wait, that last thing is just macros (...duh) 23:53
jnthn Well, time for some rest... 23:54
Hmm...it's $dayjob's birthday tomorrow. I think that means cake...
