ZoffixLappy Why does this fail?
WhateverCode doesn't close over $rovers I guess 00:12
Hm, and even if I use a { $_ ∈ $rovers } with my Subset::Helpers sub that takes it as &code, it tells me $rovers is an Any :/ 00:14

psch ZoffixLappy: subsets are compile time
ZoffixLappy: which means, during "subset RoverName ..." the name is known, but it doesn't have a value yet 00:15

it's terrible

psch i also know that cffa68807e6390d195f6d0f373c8c79b15fb9a61 has the fix for an unrelated build error for r-j 00:27
so i plan to rebase that fix back to before 2015.11 and bisect then 00:28
it'll probably go up in smoke in a lot of ways

Xliff timotimo, Yeah. The lib allocates for me. 01:06
I will try that. Cheers.
01:07 vendethiel joined
Xliff timotimo, so how do I pre-allocate the pointer? 01:07
Or should I just pass a scalar?
skink Pointer[CArray[CArray[num32]]] 01:08
That's just silly :D
timotimo actually, you can just pass it an int64 :P 01:09
but other than that, i'd build a CArray to receive it, give it a single slot to put stuff into
actually ... maybe "is rw" will do the extra pointer for you
Xliff Hmmm... 01:10
Worth a try.
Pointer[CArray[CArray[num32]]] segfaulted.

timotimo will the p6 part go into the same gist as a second file?
Xliff Updated with P6 part. Same link. 01:54
No. I usually do everything in one .md file for the highlighting.
ZoffixLappy Any idea why this code results in -> ;; $_? is raw, (code blocks?) pushed into my <photos> array? gist.github.com/zoffixznet/759afef...bed14ffde0

camelia rakudo-moar 617bb4: OUTPUT«[{:ber("boor"), :foo("bar")},]␤»
timotimo because you refer to $_ iside it 01:55
inside*
ZoffixLappy :/
How do I fix it?
timotimo give the variable a name
alternatively, you could use $/ and the shortcut syntax that goes with that 01:56
m: my @res; for ^5 { @res.push: { a => $_, b => $_ + 2 }; }; say @res

ZoffixLappy Weirdest wat I've encountered so far.

camelia rakudo-moar 617bb4: OUTPUT«[{a => 0, b => 2} {a => 1, b => 3} {a => 2, b => 4} {a => 3, b => 5} {a => 4, b => 6}]␤»
ZoffixLappy Guess ^ that is also an option
timotimo yes
you can also force interpretation as a hash by prefixing the initial { with a : 01:58
that'll give you an object hash, but that shouldn't be a problem
Xliff timotimo: Other thing I may want to try is to see what happens when I return the allocated pointers, rather than using a rw param.
01:59 Herby_ left
timotimo i didn't know you had the freedom to choose that 02:00
02:00 skids joined
Xliff timotimo, for the use-case, I don't 02:00
It would just be an experiment.
If it works, I'd have to add a lib that would wrap the calls that pass data this way. 02:01
And then point P6 to those routines
Obviously, I don't want to do that. But it's an option.
Of course, I'd then have to bundle that lib. PITA. 02:02
timotimo it shouldn't be needed, we should be able to figure this out 02:03
skink I'm trying to figure out what's going on in the previous gist tbh 02:07

timotimo where is that gist? 02:11

Xliff Oh. I forgot to update that with sortiz's better implementation of as_blob. 02:17
skink Well a char[282] would just be Buf/CArray[281] = 0 no?
Xliff Done.
timotimo can't just put that into a CStruct, though 02:18
Xliff Can't pass it as a sized-C array since, again, the allocation is performed by libogg.
skink agh
Xliff And yes, inside a C-struct. Embedded.

Make the standard module blurb more useful

Link to docs, not source, and mention NativeCall too.		 02:25
Xliff skink: Donno. May look. 02:27
Still. Most of the things I am running into are standard practices for C libs. If NativeCall is going to bind to them, these are issues that will need to be dealt with. 02:28
NativeCall not being able to handle/represent a pre-allocated array is a big issue. 02:29
skink There is VorbisFile, which claims to be a higher-level and more convenient API 02:30
Xliff Thanks. I'll look into that one.
skink In which I do not see any big ol' char arrays
www.xiph.org/vorbis/doc/vorbisfile/
Xliff Look for many *'s in a row.
Coz I've got a working solution for char arrays, even if it is ugly.

Where is the use of the \ sigil documented?
MadcapJake doc.perl6.org/language/variables#Si..._variables 03:53
Xliff Yeah. Reading that now.
MadcapJake In this case, it was a shot in the dark. didn't seem to make a difference
Xliff Wouldn't you need a container to hold the return value of myhtml_tree_create() ? 03:54
Or is the context-less binding assignment the wholepoint? 03:55
MadcapJake no it just returns a pointer
it's immutable when sigilless 03:56

Xliff "Tree is repr('CStruct');" but I don't see any struct members.
Right. I get that it's immutable.
MadcapJake well I wouldn't need a container for it then because I only assign it once. 03:57
Xliff Is there a .h file for /usr/local/lib/libmyhtml.so? 03:58
MadcapJake yeah the CStruct thing was also a shot in the dark, it was a CPointer and still gave the same error. Thought it *really is* a struct
github.com/lexborisov/myhtml/blob/...html/api.h
I copied the doxygen over
Xliff Yeah. I've had better luck with CStructs that actually have a definition than with CPointers.
I think you will need to add this to your Tree class, at the very least. 04:03

MadcapJake, gptrixie is your friend. 04:06
A lot of editing, though.
I would just translate the types and put them in their own unit module. You've already done everything else, looks like.

teatime well they're both really ints of some width. typedef just makes an alias for a type. 04:29
Xliff MadcapJake, I don't think there's much of a difference, since the typedefs look to just be constant declarations of the struct class.
teatime so I guess it's the same as the same situation w/ a struct or union.
MadcapJake strange that this struct contains both
Xliff MadcapJake, linky?
MadcapJake that struct at L160 you linked above
the enums and the encodings are both structs, one just has a typedef the other not 04:30
github.com/lexborisov/myhtml/blob/...#L208-L219

teatime maybe they typedef things that are part of the public api
or typedef things that are supposed to be black boxes to the user of the public api.

And would there be any reason as to why precomp would need to open > 10 instances? 08:30
Or >5, really.
08:33 Vlavv_ left 08:38 leont left 08:40 tardisx joined
Xliff Let's try another tack. What would be the best way to look for a precompilation loop? 08:40
08:42 tardisx left
moritz there's got to be some logic right now that determines which modules need which others, and which of those can be precompiled 08:43
that's where loop detection should go, IMHO
maybe nine_++ has a good idea?
Xliff Because I think I am running into that.
Probably because of the weird way I tried to hack something that MadcapJake was working on. 08:44
nine_ I don't think we currently have a protection from recursive use statements. So if A uses B and B uses A, you'd get an endless loop trying to precompile those dependencies and that will look like a very deep perl6 process tree. 08:48
When starting from a clean slate, you'll see one perl6 process per dependency tree layer. So A uses B uses C uses D will give you 4 perl6 processes, at least until D is compiled. 08:49
Xliff Crap. 08:52
I think that's exactly what has happened.

MadcapJake Ahh well hotel, you should just use the msi package, wouldn't that work? (haven't looked at the U on W thingy yet) 14:12
ugexe having a list of recomended modules thus far has only resulted in constant 'i cant get anythign installed because XXX fails', where XXX is something new each month
hotel I want to use shiny tools wherever possible
so yes, technically I could use the msi 14:13
but I enjoy making life difficult :)
MadcapJake hotel: I know the feeling :)
Woodi ugexe: this is point when "maintain text file" comes into play ;)
ugexe Woodi: yes, just like maintaining star
which suffers from exactly this
once `emulates` and `supercedes` works then things will be easier as they imply their interface only, not implementation 14:14
MadcapJake Xliff: it's strange because I was able to get this working in my early pre-modularized version. I think I will try to separate out all the nativecall subs and export them so I can see if at least using the bare subs still works.

hotel is there supposed to be a version set right after building? 14:29
ugexe can you clarify what you mean by that? do you mean `perl -v` has output, or rakudo setting the version of moar/nqp it needs before trying to build them? 14:30
hotel welp, looks like broken things are, in fact, broken
rakudobrew build panda
gives me rakudobrew: No version set.
[Coke] ... if "build moar" failed, don't expect panda to work. 14:31
hotel well yeah
[Coke] can you show us how it failed?
hotel sure
ugexe ah, im not sure what it means from rakudobrew. my guess is it has no versions of perl6 stored in its lookup since it failed
hotel well then i run rakudobrew switch moar-nom
and building panda still fails
ugexe you have to rakudobrew rehash first most likely

[Coke] You are the first person to try this, no doubt.
timotimo www.reddit.com/r/perl6/comments/4f...ot_debian/ - this also had to circumvent executable stack 14:35

timotimo so there's the flag that can set the "noexecstack" feature
stmuk I saw something similar on alpine linux

timotimo iiuc we need execstack for dyncall or something? 14:36

(for some reason, when I switch back to pointers, I'm getting a strange "Native call expected return type with CStruct representation, but got a CPointer" error, when that function has always returned an int32...) 14:40

timotimo rakudobrew should have told you to put something in your $PATH, did you make sure it got in there? 14:42
like, echo $PATH or so?
ugexe its failing before finishing 14:43
hotel the thing is in my path
and in fact it's there twice
wait
~ is an alias for /root/? 14:44
ilmari ~ is expanded by the shell to the current users's home directory
timotimo ugexe: you don't know that, after fixing the noexecstack, who knows what exactly fails now
Xliff MadcapJake, Yeah. I went the Pointer[CStruct] route, but all that does is cause an exception.
timotimo sometimes, ~ in path won't get expanded
ilmari it only gets expanded at the start of a word and if followed by space or / 14:45
Xliff I have run into this issue in another form, earlier. I just can't remember what I did to solve it. *sigh*

timotimo hotel: you may want to stop using rakudobrew and start manually fiddling around in the build directory 14:59
hotel what would I even do?
Xliff so why is mchar_async NULL?
timotimo you cd into the folder that has rakudo in it 15:00
hotel well yeah
Xliff MadcapJake, that is below rakudo and into libmyhtml.so
timotimo then you execute "strace -o logfile.txt ./perl6-m tools/build/... ..."
RabidGravy so now to build it in hardware

hotel according to apt, strace is already the newest version
timotimo drmemory.org/strace_for_windows.html - ? 15:05
hotel ^^
Xliff It still throws a SEGV, but that is in libmyhtml, now. Still not sure if there is something funky in the initialization, though.
sena_kun I can use methods from IO::Spec::Win32 on gentoo linux, for example, but is it really sane/normal to use any of classes then?
MadcapJake Xliff: well that's a good start! Thanks! I'll finish moving this all out and then give it another go. 15:06
RabidGravy sena_kun, use $*SPEC
Xliff MadcapJake, kk. 15:07
sena_kun RabidGravy, thanks.
RabidGravy it should always give you the most appropriate
timotimo hotel: my ideas end here :)
hotel well, thanks for helping
timotimo you can put lots of debug prints into the install-core-dist.pl file 15:08
and narrow down the failing piece of code a bit more
stmuk strace is an evil hax0r tool not required in the "enterprise" :)
Xliff stmuk: I ♥ strace. As long as you don't tell the CTOs it's being used, we're all fine. 15:10
hotel well according to the error, make failed at rakudobrew line 58
Xliff What they don't know won't hurt them.
timotimo you're looking at the wrong line there
hotel hm
oh?
timotimo see, it just executes "configure + make install" in the shell
hotel oh
that's /helpful/
timotimo the --make-install flag tells configure.pl to execute "make install" when it finishes configuring stuff 15:11

Xliff MadcapJake, I think I found it. My version has two MyHTML classes. 15:19
They need to be merged with MyHTML set to repr('CStruct'), not repr('CPointer')
jnthn hotel: They probably tested that. :) 15:20

pmurias MadcapJake: made a pull request 15:42
MadcapJake: BUILD was being called, it's just that it's return value doesn't end up the return value of new 15:43

The return value of BUILD is irrelephant.
Xliff pmurias, found it already
I just haven't had a chance to get it all cleaned up.
Also found why $!tree was NULL. 15:45
And there was a parse multi that wasn't passing it to one of the myhtml_parse_* functions 15:46
But I need to apply these to a clean clone.
pmurias jnthn: yes, the code assumed that the value of BUILD was used and as such segfaulted 15:47

jnthn No
Xliff I need go to build hub to create a PR
MadcapJake, I think you aren't passing $!tree in one of those instances. 15:59
pmurias the docs for CStruct need fixing, had to read the tests to check what it does
jnthn That's rare, and some C compilers even whine about it "maybe not being supported widely" (though in reality it is, but I'd be surprised to see it widely used)
pmurias: Please patch the docs with your improved understanding, if you've time, or file a doc issue if not :)

You're returning the reference to the key and assigning the value. 17:42
ZoffixW The only difference between the two is the explicit use of `return` in the failing example.

smls ^^ Why does a subsignature promote positional pair arguments to named arguments? 17:47
Is that a bug?
MadcapJake smls: because you're destructuring a list, maybe? 17:49
smls yeah but the list has two elements, the first of which is a Pair object 17:50
MadcapJake but the destructuring you do happens inside a list in the signature
in the first case, the list is gobbled up by *@_ and leaves nothing for *%_
in the second case, you place the *%_ inside the list destructurer 17:51
smls Ok, then let me rephrase: Why does list destructuring promote Pair elements to named arguments? 17:52
In my use-case this was a rather big WAT 17:53
MadcapJake it's not promoting to a named argument, it's slurping pairs into a hash
smls I want to slurp them into an array though... :)
just like any other element of the list 17:54

ZoffixW psch, well, it's not enough when you use explicit `return`. So it's a narrow usecase where you just want the last operation to be rw. If you want to be explicit or to return in the middle of the sub, you need to return-rw. So may as well just use return-rw and not bother with `is rw`. I'd expect `return` to be a `return-rw` if the `is rw` trait applied on the sub. Seems more useful and consistent. 18:04

smls MadcapJake: So the behavior is intended? (A [ ] sub-signature for a Positional arg doing a List->Capture conversion that promotes Pair elements to the Hash-like part of the Capture)?
psch ZoffixW: i can't think of a case where an explicit return can't be turned into an implicit return
ZoffixW: i do agree though that having return mean return-rw for any 'is rw' sub would be more convenient 18:07
smls MadcapJake: That kind of means that when you put Pair objects in datastructures, you enter a minefield... :( 18:08
MadcapJake smls: just use |

psch ...probably not helpful :/ 18:10
smls MadcapJake: In my usecase, I'm trying to loop over a list where each element looks like ($string, [$pair, $string])
And would have liked to unpack those right in the loop signature
that's why the example I showed used a sub-signature 18:11

smls I guess we have to treat pairs like junctions: Only use them as transient objects *within* a self-contained piece of code (e.g. to construct hashes), and don't pass them across routine boundaries to other code that expects "normal" objects... :( 18:16
ZoffixW Created a ticket with the suggestion for `is rw` to have `return` => `return-rw`: rt.perl.org/Ticket/Display.html?id=127924
smls, I think they work fine, when you specify that you're expecting a Pair: github.com/rakudo/rakudo/pull/743/...3bf1c3R292 18:17

psch MadcapJake: you're getting something that doesn't have a .Str method
or .gist or anything really
smls ZoffixW: I don't follow. What should I be looking for in that link?
psch m: sub foo([Str $s1, [Pair $p, Str $s2]]) { say $s1.^name; dd $p.^name; dd $s2.^name }; foo(['hello', [:a, 'world']]) 18:20

MadcapJake psch: what? the two strings and a pair have Str/gist methods
ZoffixW smls, sorry, the very top line that uses Pair in the signature. I believe MadcapJake is showing an example above
psch MadcapJake: that's the thing, they aren't Str or Pair objects
MadcapJake: note that the HOW can't even stringify itself
MadcapJake what are they then? 18:21
18:21 cdg left
MadcapJake how do I print the raw signature? 18:21
of the arguments given, not the excepted parameters
s/excepted/expected/
psch what does that mean?
ZoffixW m: sub foo([Str $s1, [Pair $p, Str $s2]]) { say $s1.^name; say $p.^name; say $s2.^name }; say &foo.signature
camelia rakudo-moar 1aabef: OUTPUT«(@ (Str $s1, @ (Pair $p, Str $s2)))␤»
smls ZoffixW: That doesn't use a subsignature though. Passing a Pair directly in a signature works fine. Only the destructuring that happens in (among other places) sub-signatures is affected.
MadcapJake psch: as in, JavaScript-style arguments 18:22
sortiz ZoffixW, The source suggest that 'return' explicitly remove any 'is rw', see: github.com/rakudo/rakudo/blob/nom/...pm#L33-L42 the details escape me.
18:23 domidumont joined
psch MadcapJake: okay. what does that mean? 18:23

ZoffixW MadcapJake, that ^?
psch oh
ZoffixW MadcapJake, it seems like a bug. If you replace the pair with something else, the weird error disappears
MadcapJake yeah that, wish it didn't need to be a separate param list though
psch yeah, probably. we only have "all arguments as passed" if you put the capture explicitly

ZoffixW That's the first arg being an Int instead of the Str, but error message doesn't talk about typecheck
psch i'd guess it's that the destruct throws a BOOTException or VMException 18:30
eh, probably not, those still .WHAT correctly
well, BOOTException at least does iirc
ZoffixW Ah... and I'm guessing the Pair gets interpreted as a named arg, so the Pair positional fails typecheck and that's why you get the stringify error instead of the typecheck
psch yeah, the binding into the the subsignature fails and doesn't get turned into a proper Exception 18:31
at least that's what it seems like from here, i haven't looked at destructuring or subsignature binding

MadcapJake that could be a way, instead of layering lists, store the inner list as a pair with the key being a pair, that way there's only one layer of sub-signature and your data is properly represented. 18:40

ZoffixWin Seems not. 22:10
m: package Foo { role A { sub talk is export { say "hi" } } }; import Foo; talk
camelia rakudo-moar bd4400: OUTPUT«hi␤»
ZoffixWin This works tho
grondilu it's ok. That was silly of me to put the sub in the role anyway.
lizmat m: class A { sub talk is export { say "hi" } }; import A; talk 22:11
camelia rakudo-moar bd4400: OUTPUT«hi␤»
lizmat hmmm... feels to me the import should auto-pun the role
jnthn Well, it stems from this: 22:12
m: class A { sub talk is export { } }; say A::.keys
camelia rakudo-moar bd4400: OUTPUT«(EXPORT)␤»
jnthn m: class A { sub talk is export { } }; say A::EXPORT::DEFAULT::.keys
camelia rakudo-moar bd4400: OUTPUT«(&talk)␤»
jnthn m: role A { sub talk is export { } }; say A::EXPORT::DEFAULT::.keys

jnthn And that is because the body of a role is generic
So there's no unique sub to import
lizmat hmmm... 22:13
jnthn (Consider `role A { sub talk is export { say $?CLASS } }`
RabidGravy presumably:
m: role A { our sub f() { } }

RabidGravy yeah 22:14
jnthn Maybe "is export" on a sub in a role should say the same thing
I'm pretty sure punning - at least as it stands today - wouldn't actually do it 22:15
Might be twisted into doing it
Though I have a slight suspicion there'd be some surprise lurking there too
22:16 geekosaur joined
RabidGravy I'd go with the error 22:16
jnthn It's the conservative option at the very least. :) And wanting it to work my signal confusion anyway. 22:18

grondilu I'm still thinking about how I'll do code generation for my Versor module. I'm considering making a role with a bunch of unimplemented methods or operator subs, exporting them, and them implementing this role with classes defined by EVAL'ed strings. 22:20
FYI: github.com/grondilu/versor.p6 22:22
it's something I really want to do eventually but it's kind of complicated. Any advice welcome.
I gave up on a straightforward translation from javascript as the code generation part was too confusing. But now that I made it more perlish I still struggle to see how I'll do the code generation part. 22:24
I'll definitely use EVAL at some point but it's not simple.

ZoffixWin Ah, I see 22:48
grondilu smae time
ZoffixWin You owe me a coke :)
grondilu I can't generate the code too early though as I need to do stuff in order to know how to generate it :P
but the solution my $class = EVAL 'class :: {...}' is fine. 22:49
on the other end I suppose I could create empty classes at compile time, and then augment them with MONKEY-TYPING 22:51
22:51 cpage_ joined
grondilu s/other end/other hand/ 22:52
actually no I can't do that as at compile time I don't even have the names of the classes I want to generate. 22:54

RabidGravy I do something similar in the tests for the JSON::Infer

skink Does this look like sane types/behavior for a password-based key-derivation multisub? 23:06
my (Buf $key, Str $salt) = argon2-keygen(Str $pwd, [params])
my Buf $key = argon2-keygen(Str $pwd, Str $salt)
23:06 khw joined
ZoffixWin If [params] are optional named arguments, sure :) 23:10
skink mhm 23:16
I think perhaps $salt in this case may actually be better off as a Buf, since a user would be more likely to be dealing with blobs in general 23:17
Like writing the salt into the header of an encrypted file, or what have you

timotimo RabidGravy: i'm having some fun with sunvox :) 23:21
RabidGravy yay!
timotimo i'm not really making things that sound good melodically, but tweaking generator settings and adding filters and such is fun 23:22
i even sampled a "meow" (no, not one the cat made. one i made) and played that. but it sounded uninteresting
RabidGravy groovy
timotimo but the drumkit instrument kind of sucks 23:23
ZoffixWin Whatchya guys talking about?
timotimo musics
also, what sense does it make to create an "acid base"?
bigperl1984 try barking. much more fun
RabidGravy the classic acid bass is a square wave with a 24db/octave with high resonance around a certain range and the filter cut-off somewhat asymmettric to the amplitude envelope 23:26

tailgate can I store an infix function in a variable? How can I use one in a statement? 23:39
23:41 tardisx joined
leont You can store a function in a variable, and call it as a function 23:41
timotimo you can access an infix operator as an object with its "long name" syntax, like this:
leont The infix is just a funny syntax for it
timotimo m: my $the-addition-operator = &infix:<+>; say $the-addition-operator(10, 99) 23:42
camelia rakudo-moar bd4400: OUTPUT«109␤»
timotimo alternatively, infix operators can be referred to with a shorter syntax:
m: my $the-addition-operator = &[+]; say $the-addition-operator(10, 99)
camelia rakudo-moar bd4400: OUTPUT«109␤»
RabidGravy or even 23:43
m: my &the-addition-operator = &[+]; say the-addition-operator(10, 99)
camelia rakudo-moar bd4400: OUTPUT«109␤»
RabidGravy timotimo, though it's just get an x0xb0x as software rarely does the weird non-linear behaviour of the 303 diode ladder filter justice ;-) 23:50
skink ZoffixWin, Agh, not so simple it seems. hash_raw() returns only the key without a header, hash_encoded() returns the header plus the salt/key base64'd together 23:51
For the type of interface I mentioned earlier, with the former I'd have to construct the header myself or create a class or something, with the latter some weird decoding and subbuf stuff 23:52
RabidGravy anyhow time to crash toodles
