ChoHag Can I have a method in a role which modifies the behaviour of a method of the consuming class? 06:56
Mostly for cosmetic reasons. I could always just use different method names in the role & class. 06:57
06:58 atroxaper joined
lizmat afaik, not with standard role consuming, as any method in a class will override the method in the role 06:59

But this doesn't: > my %rh = { rx/abc/ => 1 }; $rh.perl;

Where does the second regex go?

timotimo that's why; .Str is called to generate a key
ChoHag Ah.
Presumably a hash is not the best choice then for a map of test => actions?
Or do I just need to not use Str somehow? 07:13
timotimo you can have a hash that takes Object Keys 07:14

camelia rakudo-{parrot,jvm,moar} e9e842: OUTPUT«(Int)␤»
lizmat jnthn: seems nqp::where is already returning a boxed Int
so there's no need to box it in Mu::WHERE: nqp::p6box_i(nqp::where(self)) 08:38
or am I missing something
08:39 SevenWolf left
jnthn lizmat: Yes, you are. 08:43
08:43 thou joined
jnthn lizmat: How did you determine it's a boxed thing? 08:44
lizmat: I suspect it's just the code-gen auto-boxing it for you, 'cus you did e.g. .WHAT on it.
lizmat: I don't know how things are today; I know the code-gen for MoarVM will always do the right thing in that regard.
lizmat ah, ok
jnthn lizmat: I forget if Parrot's code-gen is a bit more sensitive.
It certainly was at one point
But maybe not since the QAST do-over 08:45
lizmat anyway, I shouldn't touch Mu::WHERE then :-)
08:46 pecastro joined
jnthn lizmat: Well, doing it that way isn't harmful, as the compiler would emit it anyway. 08:46
On Moar/JVM bakcends, at least.
lizmat but would it not be boxed twice now? 08:47
08:47 thou left
jnthn huh? 08:48
The auto-boxing happens if the thing is used in a context that needs an object.
nqp::p6box_i does not supply such a context; it's a think that needs a native int.
lizmat ah, indeed: 08:51

arnsholt Doesn't penser que take the subjunctive? O:) 09:02
jnthn But subjunctives are hard... :P 09:03
arnsholt And sort of superfluous in French (but don't tell l'Académie Française =)
Apparently Spanish still uses them to give different shades of meaning, but French has pretty much stopped doing that entirely 09:04
09:04 atroxaper left
cognominal even many french got it wrong : "si j'aurais (sic) su, je n'aurais (sic) pas venu" 09:04
arnsholt Yeah, there's a huge gap between actual spoken French and the prescriptive written version 09:06
Thankfully I can mostly get away with not thinking about the subjunctive, since it's often identical to the normal present when spoken =)
lizmat refrains from speaking French online :-)
arnsholt I usually refrain from speaking it when not in France, but I don't mind eavesdropping when there are French-speaking people around =) 09:09
moritz Norwegian killed my French 09:11
whenever I try to remember a word in French, my brain helpfully comes up with the Norwegian word (if I know it) 09:12
brrt moritz, how does that happen :-) norwegian and french are not exactly similar 09:13
arnsholt It's very common 09:15
Apparently all languages that you're learning and where your skill is in the lower range, it all gets sorted into a big bag labelled "miscellaneous" or something like that 09:16
xiaomiao gets worse when you learn more languages 09:17
jnthn The big bag is great for pulling multi-language puns out of, though. :)
jnthn sucks at all languages, but can pun ok :P
arnsholt That is true =)
brrt apparently, the grammatical word / sentence structure of spoken language is not encoded in the sounds - i.e. there is no distinction between a end-of-sentence pause, an end-of-word pause, and an end-of-syllable pause 09:24
i.e. the grammar of language is 'constructed' by the brain on top of the sounds, on the basis of what its knows of the language 09:25
and i wonder how this relates to computer languages, i.e. the criticism of perl being line noise
xiaomiao I think that's mostly because perl deviates from most other languages in two ways 09:27
one is implicit stuff, which is "offensive" to some
brrt which is natural in real languages 09:28
xiaomiao and the other is the very high "density" achieved by using almost every ascii-character in the syntax
09:28 FROGGS joined
xiaomiao it takes some time to understand that, and figure out why it's not bad 09:28
brrt as does c, by the way, and c++

[Coke] lizmat: how do you know to add the INC entry if you didn't create the dir? 13:54
(I'm not saying this is a common usage, but isn't this a change from p5?) 13:55
lizmat it *is* a change from p5
but S11 changes in a lot of ways from p5
[Coke] ok. 13:56
lizmat I'm not even sure we need to expose @*INC as such
that by itself feels very p5ish
in any case, that change reduces the number of @*INC entries on my machine from ~10 to 2 13:57

lizmat if it should be possible to add a non-existing path to @*INC, we can always add a flag to the constructor for it 13:59

20:57 spider-mario joined
FROGGS that is why Perl 6 is meant to let you choose your unicode version for your part of your program 20:57

[Sno] btw FROGGS - you tell me when p6 can support native binding - I'd like to add support like Unix::Statgrab to p6, too 21:16
or tell Liz and she tells me next niederrhein.pm 21:17
FROGGS [Sno]: we have NativeCall that should do the trick 21:18
[Sno] nope
FROGGS no?
why not?
[Sno] I tried to explain that to you in Lyon and to someone in Kiev
FROGGS ahh, I remember some weird discussion :o) 21:19
but sadly not too many details :/
[Sno] because NativeCall want eg. to know about bitwidth of parameters
FROGGS yes, that is something that needs to get better
[Sno] I have some experience with native binding in several "VM"'s 21:20
the concept of native call don't work for API's like libstatgrab
SDL is written for special bitwidth, iirc - for portable data types 21:21
FROGGS problem is when we do not have a piece of code that needs some feature, it is hard to implement it
no, not really
[Sno] so if you need piece of code, check out libstatgrab ;) 21:22
FROGGS you also have to care about endianess and graphic card hardware etc
[Sno] but in SDL you can control all that, can't you?
FROGGS how have are about that when making the bindings, and for some bits the "user" has to care 21:23
s/how/you/ 21:24
grrr
you have to care about*
(I'm tired)
[Sno] "you" in sense of "you as the author of the C library"?
FROGGS you as the author of the Perl module that provides the bindings 21:25
[Sno] we shouldn't mix to much side-discussions in there
the Perl module can't guess the bindings - we tried in Kiev and it failed and dumped always
FROGGS you usually can't guess, correct 21:26
[Sno] what is needed is some kind of registering as XSUB in p5 provides (newXSproto_portable ...) 21:27
C code can guess easily 21:28
FROGGS well, you have more information at that point, information you cannot obtain by just looking at a lib 21:29
[Sno] precisely - and p6 should provide a way to get the "more of information" in some way 21:31
anyway - tired, too
FROGGS yeah 21:32
[Sno] but let's keep in touch regarding that
FROGGS perl6-m -MNativeCall -e 'sub get_cpu_totals() returns Int is native("libstatgrab") { * }; say get_cpu_totals()' 21:33
140576014886592
[Sno] long running monitoring appliances isn't a worst early adopter scenario for p6 ;)
FROGGS now we'd need to unpack that mem to cpu_percent_t :o)
[Sno] but it doesn't return in - it returns a pointer to a list of structs
while sizeof(int), sizeof(long) and sizeof(long long), size_t, time_t and void * are surprisingly different here and there (depending on compiler settings etc.) 21:35
padding of structures is interesting, too
FROGGS yes, these are things that are hard to implement, but still possible 21:36
[Sno] I think, having an API like all other VM's provide to C side would be sufficient 21:37
jnthn I suspect NativeCall should export c_int, c_long, c_long_long, c_size_t and so forth.
[Sno] jnthn: and how code the padding? enums?
FROGGS perl6-m ../statgrab.pl 21:38
cpu_percent_t.new(user => 2.80321910516779e-39, kernel => 0e0, idle => 7.00820190575056e-40, iowait => 0e0, swap => 2.63626055885674e-38, nice => 0e0)
jnthn Struct padding is already computed by the alignment of the system you're doing the calls on.
FROGGS does not look that correct yet
[Sno] FROGGS: call it twice
wait a second between the calls
FROGGS perl6-m ../statgrab.pl
cpu_percent_t.new(user => 2.80491607760809e-39, kernel => 0e0, idle => 7.0124898790514e-40, iowait => 0e0, swap => 2.64180325480253e-38, nice => 0e0) 21:39
[Sno] jnthn: the passing might change depending on compiler flags or __attribute__()
passing => padding
FROGGS perl6-m ../statgrab.pl 21:40
cpu_percent_t.new(user => 9.8447437286377e0, kernel => 2.46111631393433e0, idle => 87.6699752807617e0, iowait => 0.0959397628903389e0, swap => 0e0, nice => 0.0241753086447716e0)
that's better
[Sno] rtfm helps ;)
FROGGS I used the wrong C function before
[Sno] how? which wrong one? 21:41
FROGGS %Cpu(s): 9,8 be, 2,5 sy, 0,0 ni, 87,6 un, 0,1 wa, 0,0 hi, 0,0 si, 0,0 st
first I called get_cpu_totals, and the latter was cpu_percent_t *cpu_percent_usage(void);
but you see, the numbers are correct 21:42
the %Cpu line is from `top`
that is the script: gist.github.com/FROGGS/ab192c9eac80bcd1b3c0 21:43
[Sno] but those cpu percent is just gaming ;)
jnthn Well, I don't think [Sno]'s point is "can we get it correct on one system", it's "can we get it correct portably"
[Sno] jnthn: correct
and cpu_percent is finally double[6] - so it's easy
FROGGS all I can say it that it looks like it is working for my little case here 21:44
[Sno] fs_stats is more difficult
network_iface_stats isn't to easy, either 21:45
FROGGS [Sno]: but you see you can play around with it... and when you hit a bug when trying to make fs_stats work, then we have something we can solve
IMO that is a better approach then waiting for me to tell you that it works when it works 21:46
[Sno] FROGGS: it's not worth the time, because it doesn't work portable
FROGGS [Sno]: how do you know? 21:47
[Sno] FROGGS: because we tried in Kiev ;)
FROGGS can you provide the script?
[Sno] p6 only know about int32 or int64 etc.
FROGGS: we didn't keep it after it only dumps 21:48
FROGGS :/
[Sno] but jnthn was around, he might remember
jnthn FROGGS: I already have cases where this happens on Windows vs Linux, fwiw. A C "long" can mean something different between those two.
[Sno] I told you what I think what is required - some native API
21:48 atroxaper joined
jnthn "native API" is kinda underpsecified... 21:49
FROGGS [Sno]: I cannot implement or fix something with that vague sentence, sorry
[Sno] I might have not much experience in writing new languages - but I have strong experience in binding native code into VM's in a portable way
FROGGS I'd prefer to have some specific code that cannot work right now, like calling a specific C-function and handling its return value 21:50
[Sno] let's start with: need to allocate and free VM variables (scalar, arry, hash) 21:51
need to assign values to scalars
jnthn [Sno]: Uh, you *don't* every free things explicitly at a VM level in anything Perl 6 runs on.
*ever
That's Perl 5 thing, assuming ref counting.
But it sounds like you'd like us to recreate XS.
[Sno] jnthn: nope - there're other ways doing that 21:52
jnthn uh, Perl 5 think.
[Sno] but finally any kind of marshalling needs to define a way to exchange data structures ;)
jnthn Yes, that's the point of the CArray and CStruct REPRs.
21:53 atroxaper left
FROGGS [Sno]: why do you want to alloc+free a scalar? isnt it enough to pass stuff to C function and get proper Perl 6 values back? 21:53
jnthn And there's no reason we can't parameterize them on layout strategy.
21:53 Sqirrel joined
[Sno] FROGGS: there're thing you cannot control (lack of information) when calling from perl6 -> native 21:53
jnthn: it's a runtime (link time) thing 21:54
FROGGS still, allocating a Perl 6 variable won't help you there
[Sno] it's a start
jnthn [Sno]: Most things in Perl 6 are :P
[Sno] to many special cases (enum, attribute(packed), attribute(aligned), ...)
so what you need is code a mapping where you know value range of src and tgt 21:55
XS (perl5 api) is little bit over-complex
so no need to repeat 21:56
jnthn Yes, my point in this is specifying the mapping should be *declarative*, not imperative.
[Sno] I don't get the sematic finesse of this sentence ;)
how can you specify a declarative mapping when you don't know the compiler settings for default values of sizeof(enum), attribute(packed), attribute(aligned) 21:58
in C, changing enums might change their size - but once created mapping at C level isn't affected 21:59
and think about binding Go libraries, Fortran code or C++ classes 22:00
with a native api (as Lua, Perl5, Python, ... provide) one can easily register objects and methods and have small facades/proxies calling the native objects 22:01
c++ exported functions name mangeling can be "interesting" - at least when you never seen the compiler before 22:02
jnthn For the cases where we can't reaonably have NativeCall work out, there's absolutely nothing stopping you writing such an adapter. It's just that it's this time a things NativeCall understands => the library adapter. 22:03
In fact, I think people already did this.
[Sno] yes, it's the last fallback 22:04
but always prefer better solutions
22:04 itz left
jnthn Asking for a "native API" to "the VM" in a Perl 6 context doesn't make a lot of sense. Which VM? 22:04
[Sno] it's a several step request
JVM supports it - and it's likely possible to define in Perl6 to call "external JVM functions/methods" 22:05
otherwise it wouldn't be possible to call Java code
jnthn Link me the thing you're referring to with "JVM supprots it".
22:06 denis_boyun joined
jnthn (So I've actually got a concrete example of what you're after.) 22:06
[Sno] a few years ago in a Project we played with that
I have to dig, but I always assumed there was a way
FROGGS okay, one problem with sg_get_fs_stats is that the returned structure starts with the char*, and I don't know how to build up my CStruct class 22:07
[Sno] we finally abondoned JVM for Perl5, because XS suits our requirements much better
22:08 pecastro left
FROGGS jnthn: how would I declare an 'is native' sub when the C function looks like: foo(&bar) { ... } ? 22:10
[Sno] jnthn: quick google search results in stackoverflow.com/questions/903530/...dlinkerror being something we played with (I cannot swear - it's a 70% chance)
but maybe NativeCall with some extensions as FROGGS suggest with a "compiler" for loader would be sufficient 22:12
so a "h2p6 statgrab.h" creates the loader for the system it runs on 22:13

FROGGS but it works nicely here... last time I used NativeCall it did not supported sized ints at all :o) 22:23

Change colors and create menu in the header

Begin sketching redesign based on imgur.com/a/y1dHo .
This commit changes the colors of the index page to match and adds the menu items and the css to make the header look decent from many sizes.		 22:34

Mouq If it's related to msdn.microsoft.com/en-us/library/vs...00%29.aspx 23:18
, we do have parametric roles 23:19
Which I believe are the same thing?
xenoterracide generics are actually more like compiletime templates 23:21
you put parameters in place of class/interface, and it becomes strict typed 23:22
not sure on parametric roles though
basically it's a template for types 23:25
Mouq xenoterracide: huh. I'm sure masak knows :) 23:28
xenoterracide Mouq: reading s14 yes I'd say parametric roles achieves basically the same thing 23:38
