Woodi so, what is teoretical mining of ':' in perl6 ? eg. one used in ':2nd' above :)
Mouq ':something' is a pair or adverb. It's just sugar, and the list is here: perlcabal.org/syn/S02.html#Adverbial_Pair_forms 05:30
Woodi ook, looking 05:31
Mouq Well, sugary
r: my $str = "I love books, and they love me". $str ~~ s:2nd/love/hate/; say $str 05:33

Mouq r: my $str = "I love books, and they love me"; $str ~~ s:2nd/love/hate/; say $str
camelia rakudo e22ac2: OUTPUT«I love books, and they hate me␤»
Mouq I guess for matches they're actually called 'Modifiers' S05:171 which is probably for the best since they don't actually de-sugar like normal adverbs 05:36

Woodi why Pairs are "extracted" to separate type/form ? something like lists or just sugar ?
Mouq "All of the adverbial forms (including the normal ones with identifier keys) are considered special tokens and are recognized in various positions in addition to term position" 05:41
I guess calling them sugar is wrong. They're a chunk of the language 05:42

nwc10 aristotle pointed me at programming.oreilly.com/2013/10/dea...luded.html (which links to www.leancrew.com/all-this/2012/04/p...th-others/ ) and possibly related is also www.python.org/dev/peps/pep-0439/ 09:55
ie - the downsides of having a "batteries included" philosphy, that at least some Pythonistas think that Perl is better at OO glue (so Perl 6 ought to steal the best process starting API from CPAN) and that Python is belatedly shipping a module installer in core. 09:56
tadzik oh, is it just me griding my teeth upon the division operator overloaded to do paths? 09:58
(grinding?)
nwc10 no, I am too. IIRC Boost does that, and I don't like it at all
jnthn Or how C++ has << overloaded for output? :) 10:01
diakopter I have whitespace overloaded for concatenation 10:03
nwc10: did you try it on the pi yet? :) 10:05
nwc10 not yet. Pi's SD card is rather unhappy. 10:06

*brain
tadzik my pi's sdcard is always unhappy :( 10:12
it doesn't like surprise power downs
diakopter my galaxy's sdcard makes my galaxy unhappy, even though it's Samsung also 10:13
GlitchMr <jnthn> Or how C++ has << overloaded for output? :)
I hate iostream interface.
yosefk.com/c++fqa/io.html 10:14
nwc10 jnthn: I guess I'm sort of prepared to overlook << and >> because they seem to end up being pretty sucky for actually coping with any real file formats I ever had to deal with
jnthn nwc10: So far in my career I managed to escape using C++, and after various discussions with $dayjob's C++ teacher about the language I'm not in a hurry to need to know it. ;)
GlitchMr I personally find C++ worse than PHP. 10:15
nwc10 yes, keep your remaining sanity for more useful projects
GlitchMr Yes, you can use sane subset of it, except this sane subset is called C.
The only thing I could possibly miss are strings, but that's about it. 10:16
tadzik except that they're not part of C++, technically ;) 10:17
jnthn chuckles at his mail client labeling a mail from on of $dayjob's sales folks as "This message may be a scam" 10:18
GlitchMr std::string is not part of C++?
tadzik what I mean is that it's part of the standard library, not part of the language
as in, "this is not std::string"
GlitchMr Without standard library, C++ would be C with booleans and classes. 10:19
(and booleans are in C99 anyway)
It would feel like Perl without arrays and hash tables. 10:20

colomon GlitchMr: for my $work, I had to reimplement the bits of the C++ standard library I needed, because (when I started) I could not rely on my customers all using compilers that had working versions of it. 10:51
GlitchMr That makes sense.
I mean, C++ is not even a standard.
Or rather, it is, but it doesn't specify anything.
For example, name mangling. The specification says it has to be done, but not how, so everybody does it different way. 10:52
FROGGS good that our specs tend to say how it has to work too 10:53

GlitchMr C++ portability doesn't exist. 10:55
10:58 daxim left, daxim_ joined
GlitchMr Mixing C++ code? That's simple, ensure they both were compiled with the same options and the same compiler. 10:59
nwc10 IIRC the intent pretty much is that compilers do name mangling *differently*, because if they did it the same way, they would have to lay out the detailed implementation of classes and vtables byte for byte identically 11:03
GlitchMr Other languages have standarized name mangling. 11:05
For example, Foo$1 is anonymous class in method of class Foo. 11:06
11:06 c1sung left
GlitchMr (in Java)' 11:06
11:07 c1sung joined
GlitchMr Or Objective-C, which is compiled language. It also has standarized name mangling. 11:09
grondilu reads en.wikipedia.org/wiki/Name_manglin...in_C.2B.2B 11:15
according to this, if C++ does not standardize name mangling, it's more or less intentional.
11:17 frdmn left
grondilu Also: « A standardised requirement for name mangling would also prevent an implementation where mangling was not required at all — for example, a linker which understood the C++ language. » 11:17
One day there may be a C++ compiler in Perl 6, right? 11:18
masak grondilu: the standard answer to that is "yes, but you'd still have to write a VM/runtime on top of C++"
grondilu I don't understand why. Couldn't we use the same VM Perl 6 uses? 11:19
jnthn masak: A C++ compiler written in Perl 6, I think grondilu meant. Not writing a Perl 6 compiler in C++. 11:25
or that's how I read it, anyway...
grondilu yeah that's what I meant.
moritz oh my, no easy task 11:26
Timbus perl in C++... topaz??
nwc10 first, could I have a Perl 6 compiler written in NQP? :-)
pony remains optional
note, do not want a pony instead of the Perl 6 compiler, even if it's cheaper just to ship me a pon.y 11:27
Timbus plz spec pony
pony is required
moritz plz unspec Timbus :-)
grondilu I suspect once Perl6 is fast and fully functional, people will have lots of fun writting compilers for various languages. C++ won't be any exception. 11:28
11:28 moukeddar left
nwc10 pony has 4 legs, which point downwards. Is unambiguously alive (no nails or perches involved). Does not have captions in front of it (so do not confuse with a LOLCAT or similar). Eats grass, oats and similar vegetable matter, converts to nitrogen rich fertiliser. Effectively also eats money, without doing so directly. 11:30
Timbus yes but 11:31
nwc10 pony will not pass perl 6 regression test suite, however hard you flog
Timbus what colour is it
masak pony-colored!
Timbus hoho
nwc10 orange. Or the closest you can get with spray-tan.
oh, I forgot, pony is not a valid ingredient of beefburgers, cottage pie, or other cow-based food products 11:33
11:33 colomon left
nwc10 (neither is a Perl 6 compiler) 11:33

jnthn Yeah...we should deal with that at some point :) 15:26
15:28 [Sno] left
diakopter to whoever fixes that: you have to check all if conditionals that could have an implied NULL, all occurrences of NULL, all memset, and all calloc 15:28
and all occurrences of 0, for good measure 15:29
and all ternary ops
jnthn And while, and... :P

TimToady who is this "tim" of which you speak?
huf a dangerous powerful wizard iirc 15:34
TimToady 's name is "toady"
timotimo doesn't scan. www.youtube.com/watch?v=qTDvkCU3u3w
well, it does for the second part, but that's not the part that everybody knows (obviously) 15:35
TimToady is merely a toady of tims
rjbs There is more than one adjective describing you. 15:36
TimToady timid ain 15:37
ain't one of 'em
timotimo aye, it's a sign of the tims.
diakopter there's no tim like the present
timotimo o TimToady o mores! 15:38

TimToady it's really an oriental name, so "tim" is the family part, and "toady" is the given name :) 15:46
that's why I prefer to go by "toady" 15:47
it also serves as a microshibboleth when people don't know my real name and assume it must be "Tim" :) 15:53

TimToady skimming those Python articles made me realize that one of the reasons for providing more than one way to do it is to allow the language to scale properly; if there's only one way to do things, it's usually either too heavy or too light for your current purposes 16:20
it's like dealing with the government; the amount of paperwork is always going to be too little or too much :) 16:21
or a quantum superposition of those...
jnthn or just not at all :P 16:22
16:23 FROGGS joined
TimToady well, yes, "can't get there from here" is closely related to "can't get their form here" 16:24
the other alternative is to pay enough that your government just tells you what would be on your forms if you had any :P 16:25
jnthn I do receive a form. I then can send an SMS to say I agree with it, and that's my tax return done for the year. ;) 16:26
If I'm paying that much they better be doing the darn calcs for me :P

TimToady so government is like a pony: Effectively also eats money, without doing so directly. (Except, of course, when it does do so directly, but then it's more like a goat.) 16:33

TimToady well, in America you can find people horrified by nearly anything that they are told to be horrified by :) 16:46
arnsholt Is there a reason only install/bin/{nqp,perl6} are runnable outside of the repo on JVM?
TimToady: Yeah, I guess that's true of anywhere
TimToady alas, the one thing they almost never do is get horrified by the motivations of the people that are telling them what to be horrified by 16:48
arnsholt Well, the people doing the telling aren't going to tell them to be horrified by that, are they? =)
perigrin TimToady: I'm horrified by that truth. 16:49
TimToady it's always trivially easy to "justify" extremism by pointing out the other extreme
16:50 pernatiy left
TimToady and compromise seems to be completely busted here right now because the extremists can compromise, and even the people in the middle can't compromise now because that just moves things toward one extreme or the other :) 16:51
*can't compromise
16:52 SamuraiJack_ joined
TimToady We all agree on the necessity of the other guy compromising... 16:52
perigrin well the problem is that compromise *is* moving (somethings) towards one extreme or the other ... and moving *other* things the other direction. If it were everything moving in one direction it would be called capitulation. 16:55
though the extremists like to think it's called compromise still.
TimToady and we've decided to clean up all the unsanitary processes in the sausage factory; as a result, no sausage can be made anymore
we got rid of all the smoke-filled rooms and all the pork-barrel earmarks, so there's nothing to trade with 16:56
as a result, we'll likely take down the entire world economy before the tea party wakes up and smells the coffee 16:57
16:57 dansamo left
TimToady on the other hand, I'm more depressed by my broken water heater :) 16:59
perigrin that's cold. 17:01
TimToady thinks, however, that the US is straying into another period resembling the extended fight between North and South, only this time the Red and Blue are a gerrymandered patchwork, and it's hard to foresee a Missouri Compromise for that to hold things together for a few more years 17:02
and just as in the Civil War (ours, not yours :), the outcome is not really in doubt, but that won't stop them from fighting it 17:03
17:05 benabik left
TimToady well, at least we'll be able to fight using Perl 6 :) 17:06

Make the test suite run on JVM.

Here be hackery. Most notably, figuring out how to compile libraries on JVM is tricky, so for now we can run the test suite with Rakudo/Parrot to get them built and then again with Rakudo/JVM.
Also, the extension guessing doesn't, so far. It just assumes the shared library extension is so.		 17:42
arnsholt jnthn: I think there's a role mixin bug on Rakudo/JVM
If you take that latest Zavolaj commit (and replace the hardcoded .so with .dll) and run t/01-argless.t it should fail on the last test, which exercises the is symbol function 17:43
17:45 prevost left

Ulti can I suggest total is cached in Baggy and not just Bag so that roll uses the cached value 21:22
at least the way I use BagHash/KeyBag is to sample from a distribution so adding data isn't that common but I .roll thousands of times in tight loops 21:23
