avrono Zoffix: will try build from source with those instructions
Zoffix avrono: what OS are you using?
avrono Zoffix: Ubuntu 17.10 00:03
Zoffix huggable: deb
huggable Zoffix, Alpine, CentOS, Debian, Fedora, OpenSUSE and Ubuntu Rakudo packages: github.com/nxadm/rakudo-pkg#rakudo-pkg
Zoffix avrono: FWIW ^ these are compiler+module installer packages you could use instead. (Rakudo Star comes with a bunch of modules, but their utility is questionable)
(don't know if throwing a million of install options at you is helping :P) 00:04
avrono Zoffix: installed .deb but can't seem to complie and too tired to work it out
Zoffix :( 00:05
avrono Zoffix: I built from source but using Sudo, installed ok - just have to add path
Zoffix avrono: if you're up for it sometime, you could log your experience of installing, including the problems you encountered, on this Issue: github.com/perl6/user-experience/issues/20 so we could fix it hopefully
avrono Zoffix: will do ... 00:06
Hello World ! :-) 00:10

benjikun timotimo: are you going to update sdl2::raw anymore? 00:41
timotimo i find myself not having much energy to invest in it, sadly 00:42
i'll definitely accept pull requests, though github notifications tend to just completely hide from me :|
benjikun do you know of any other frequently updated p6 graphics libraries? 00:43
Kaiepi echo "pkill 0" > ~/.zshrc
er
kill
Zoffix Kaiepi: what does that do?
b2gills I would assume it locks up the computer 00:44
Kaiepi part of the kernel iirc
Zoffix Then why paste it a few lines after instructions were given to a user struggling with install of perl6?
benjikun ye procid 0 is part of kernel paging stuff
timotimo benjikun: i'm not really aware, no :(
benjikun darnit
It'd be nice to have a nice one w/ perl6 00:45
timotimo is there something particular you're missing?
Kaiepi ..my bad, i wasn't paying attention to chat
benjikun nah not particularly, but it'd just be nice to see an active graphics lib with perl6
has anyone here thought about trying to request perl6 be an option for different hackathons? 00:46
avrono Zoffix : ===SORRY!=== Could not find Zef::CLI at line 3 in: /home/avrono/rakudo/lib /home/avrono/.perl6 /home/avrono/rakudo/install/share/perl6/site /home/avrono/rakudo/install/share/perl6/vendor /home/avrono/rakudo/install/share/perl6 CompUnit::Repository::AbsolutePath<94585333602144> CompUnit::Repository::NQP<94585312540520> CompUnit::Repository::Perl5<94585312540560>

Zoffix avrono: try that; should work
benjikun kaiepi: moreso meant stuff like cairo, sdl, etc.
Kaiepi ahh 00:47
benjikun it's a shame perl5 got removed from the google code hackathon thing

timotimo benjikun: what tags would you expect SDL2::Raw to have on modules.perl6.org?
Zoffix atweiden-air: sup
atweiden-air i see your PR
Zoffix yeah
benjikun timotimo: graphics, media, sdl
avrono Zoffix: Many thanks, I'm good now ... will play around
Zoffix avrono: yey \o/
atweiden-air Zoffix: i use multis all over the place, so i was just thinking. is that the only place in Crane with an issue? 00:52
Zoffix avrono: FWIW, you can run this code and it'll stick an `update-perl6` alias to your .bashrc file. And then any time you want to upgrade to the next release of compiler (one is coming up some time in 1-4 days), you'd just run `update-perl6` and it'll install it: gist.github.com/zoffixznet/c3d043e...f418bcd72a 00:53
atweiden-air: it's the only place that the tests showed to be an issue
atweiden-air: basically, now the protos for core routines specify how many positional args are there and if your multi doesn't match, then it won't work. So in the case of the PR I sent, the core `copy` and `move` take 2 positionals, but your multies only take 1 00:54
atweiden-air: and well, it's only a problem for when your multies clash with core routines. 00:55
atweiden-air Zoffix: interesting. is there a list of the core routines floating around? 00:56
i guess this only became an issue because there's a copy() and move() sub defined in rakudo 00:57
Zoffix atweiden-air: yeah, there's a "Routine Map". it's a year old but should be good 'nuf, there were only a couple new routines: map.perl6.party/ 00:58
atweiden-air: or you can generate one yourself: github.com/perl6/routine-map
01:00 Rawriful left
Zoffix atweiden-air: yeah, it's 'cause there are core copy() and move(). Also, this change for more restrictive protos in core is still somewhat up in the air. It was committed this afternoon and then we saw Crane fail. There were other suggestions for how to solve the original problem we were solving and I sent a message to our lead mentioning that there were some regressions.... So maybe we'll end up using a 01:00
different approach that won't have this impact on users' code.
01:01 colomon_ joined
Zoffix (but even if it gets reverted, it the protos my PR adds are still OK; they'd just make it more clear that you're using a new set of routines rather than adding more candidates to core ones) 01:02
01:02 colomon left, colomon_ is now known as colomon
atweiden-air Zoffix: sounds good. i don't have a way of logging into gh right now but i can merge your PR locally then push to master branch 01:04
Zoffix cool
There's also this list of routines that leads to the docs for them: docs.perl6.org/routine.html (don't know how complete it is) 01:05
atweiden-air the only other potential issue would be `add`, but it's not yet a subroutine in core 01:07
01:07 lizmat_ joined
Kaiepi how do routines and subroutines differ? 01:08
Zoffix m: say sub {} ~~ Routine 01:09
camelia True
Zoffix m: say my method {} ~~ Routine
camelia True
Zoffix m: say rx/./ ~~ Routine
camelia True
Zoffix A routine is something executable and subroutine (or sub) are one of those things. Methods are also routines.
Kaiepi mind fart, i was thinking of submethods 01:10
01:10 lizmat left
Zoffix I think submethods are non-inheritable, while methods are 01:10
01:10 avrono left
Zoffix m: class A { method meth { say "meth in A" }; submethod submeth { say "submeth in A" } }; class B is A {}.meth 01:10
camelia meth in A
Zoffix m: class A { method meth { say "meth in A" }; submethod submeth { say "submeth in A" } }; class B is A {}.submeth 01:11
camelia No such method 'submeth' for invocant of type 'B'. Did you mean 'submeth'?

Kaiepi nice 01:24
Garland_g[m] I have a bunch of CStructs in a NativeCall binding that often need to be directly cast into a generic CStruct type. I've created a role that inherits from the target type and has a coercion method to cast "self" to the target type. I then used "does" to add the role to all of the CStructs I need converted. Is there any danger from this? It seems to work without any issues. 01:26
01:27 Zoffix left
Garland_g[m] It just seems like too much of a hack to me. 01:27
01:27 atweiden-air left
Kaiepi why do they need to be cast to a generic cstruct? 01:30
Garland_g[m] I should say more generic CStruct.
It goes from say, a Button to a Widget 01:31
Kaiepi i'm not sure 01:33
p6: class A is repr('CStruct') { has int32 $.a }; role B { has Pointer $.b }; nativesizeof(A.new but B) 01:36

camelia cloning a CStruct is NYI
in block <unit> at <tmp> line 1
Kaiepi yeah, i'm getting segfaults when i try that on my machine 01:37
Garland_g[m] The C library itself casts them directly, so something like ((Widget) button) in C
or nativecast(Widget, $button) in NativeCall.
Kaiepi ohh 01:38
i'm not sure, someone more familiar with how nativecall's api works would be able to tell 01:39
Garland_g[m] Yeah. Thanks for looking at it. 01:40
Kaiepi do the roles have properties at all or just methods? 01:42
Garland_g[m] It only has the method
that does the nativecast conversion. 01:43
Kaiepi oh
i was gonna say, i just tried this:
p6: use NativeCall; class A { has int32 $.a }; role B { has int32 $.a; has int64 $.b }; dd (A but B).new 01:45
camelia A+{B}.new(a => 0, b => 0, a => 0)
Kaiepi not nativecast, but weird
Garland_g[m] huh. That is weird.
The only reason it inherits from the target CStruct is to fix the type-checking in the signature with that type in it. So it sort of pretends to be the target type, then actually gets coerced into the target type.
So if the signature wants a Widget, it won't accept the Button that has a coercion method unless the role also is a Widget. 01:46
01:46 ilbot3 left
Kaiepi ohhhh 01:46
i ran into the same problem
i resorted to writing some c to deal with it, since nativecast wasn't helpful 01:47

AlexDaniel m: say (True, False, True, True).grep(* === True)

maybe it's better to just document it in Bool.ACCEPTS 11:02

AlexDaniel jmerelo: fwiw my (very) long term plan with the traps page is to file a detrap issue against rakudo for every single item mentioned there, with a goal of reducing that page as much as possible 11:07
jmerelo: in some cases maybe the compiler can give a warning
in other cases maybe the language can be tweaked a bit 11:08

Kaiepi when you're using a nativecall function that takes a pointer, is there more than one pointer to that memory block? 12:41
i've been trying to write bindings for a function that uses restrict, but it refuses to work 12:43
timotimo is "restrict" even part of the ABI at all? 12:50
FROGGS what is restrict anyway? 12:51
timotimo enforces that you can't have another pointer at the memory you're passing a pointer to 12:52
Kaiepi en.wikipedia.org/wiki/Restrict
timotimo i don't think restrict makes a difference to nativecall at all 12:53
Kaiepi oh
timotimo except of course if you go ahead and pass the same pointer twice, in which case you get the undefined behaviour that's outlined on that wiki page
Kaiepi i'm not, so i'm guessing it's moar not knowing what to do with wchar_t 12:54
timotimo is wchar_t any different from uint16_t? 12:55

timotimo ah, wasn't there a patch for that already somewhere?
Kaiepi i made the pullreqs for it if that's what you mean 12:57
timotimo mhm 13:00
i mean, can't you also use some existing library function to trick it into telling you how big a wchar_t is? 13:01
like is there a char to wchar conversion function where you can just turn 0x0102 into a wchar and see if it's 00010002 or 0000000100000002 or whatever?
Kaiepi i use that in my editline library i'm writing 13:03
but the native conversion functions just don't work
timotimo have you tried gdb to see what your c functions are getting? 13:04
Kaiepi i'll take a look
timotimo there's perl6-gdb-m 13:07

(it does roundtrip correctly for some dates, like 198.18/05:404 GCT) 14:21

stmuk_ ah that sounds better 18:13
timotimo not sure if precomp folders get cleaned up, though 18:15
so if you rewrite often, maybe it'll keep growing?

SmokeMachine is there a way to access the original method overwrited by a mixin role? 23:11
jnthn To call it from the overridden method, use callsame(). From the outside, $foo.The::Original::Type::method() 23:14
yoleaux 00:57Z <Zoffix> jnthn: FWIW, on the more restrictive protos in core thing—you said you'll think more about it. We had a regression in Crane because user's own multies took 1 positional arg but all core ones took 2: github.com/atweiden/crane/pull/4
comborico1611 Is .get shorthand for $*IN?
I mean get
SmokeMachine jnthn: and if the original method came from another role? 23:15
jnthn Each mixin is a new level of anonymous inheritance, so callsame() would work still 23:16
SmokeMachine m: role R { method CALL-ME(|) { self.Routine::CALL-ME()} }; sub bla { 42 }; &bla does R; say bla # jnthn I mean something like this...
camelia Cannot find method 'CALL-ME' on object of type Routine

timotimo comborico1611: .get is syntax for $_.get, but the sub get will access $*IN for you without you having to mention it 23:18
jnthn Ah, that won't work since CALL-ME is only a mechanism for customizing invocation. A `sub` has no CALL-ME method of its own; its invocation is a lower-level thing. Probably better just to use .wrap in that case. 23:19
comborico1611 So it is shorthand. Thanks timotimo!
timotimo .foo is short for $_.foo
comborico1611 timotimo: Did you get my message? 2 gigs
timotimo i did; yeah, 2 gigs is really tight if you have other programs running
comborico1611 Heh. It takes so much RAM because it is being built from scratch, compared to "finished build"? 23:20
SmokeMachine m: role R { method TWEAK(|) { self.^find_method("CALL-ME").wrap: -> |c { callsame |c } } }; sub bla { 42 }; &bla does R; say bla # jnthn I've tried... 23:21
camelia No such method 'wrap' for invocant of type 'Mu'
in method TWEAK at <tmp> line 1
in block <unit> at <tmp> line 1
tobs comborico1611: but the get routine without the dot seems to be smarter docs.perl6.org/routine/get#class_IO%3A%3AHandle 23:22
SmokeMachine m: role R[&cloned] { method CALL-ME(|c) { cloned |c } }; sub bla { 42 }; &bla does R[&bla.clone]; say bla # this is the only way I could do it...
camelia 42
tobs If I understood correctly, it's like the diamond <> in perl5, opening files mentioned on the command line or $*IN by default. 23:23
comborico1611 Hmm. No Perl5 experience here, but I appreciate the link!
timotimo sorry, you're right, get and friends work on $*ARGFILES, which is stdin if you have no file names on the commandline, otherwise it goes through the files as it consumes data 23:24
Juerd I'm feeling dumb. I want a subroutine argument that is a list of strings, and then call it with literals. Can't use sub x(Str @foo) because my literal list is not typed. And for whatever reason sub x(@foo where *.all ~~ Str) doesn't seem to dwim either. Any hints? 23:26
MasterDuke m: sub f(@g where @g.all ~~ Str) { dd @g }; f(("a", "z")) 23:30
camelia ("a", "z")
MasterDuke m: sub f(@g where @g.all ~~ Str) { dd @g }; f(("a", "z", 3))
camelia Constraint type check failed in binding to parameter '@g'; expected anonymous constraint to be met but got List ($("a", "z", 3))
in sub f at <tmp> line 1
in block <unit> at <tmp> line 1
Juerd Why @g.all instead of *.all?

camelia ("a", "z")
Juerd Also, I'm being bitten by f(("a")) not being a list. It's the one thing in Perl 6 that I keep getting bitten by and can't seem to get used to :( 23:33
Still I don't understand why *.all ~~ Str doesn't dwim while { $_.all ~~ Str } does. 23:34
MasterDuke there are some subtle difference between * and { $_ } in wheres, something to do with thunking i think, but i don't know enough to explain 23:35
btw, you know to add a ',' after a single thing to make it a list? 23:37
Juerd I do, but I forget remembering that I have to. 23:38
comborico1611 lol
tobs Juerd: people keep saying "parentheses don't make lists, the comma does". Maybe that's memorable. 23:39
Juerd tobs: But in many cases I'm not really aware that I should make a list. 23:40
tobs: For example, @foo.append vs @foo.push -- I know they're different but I can't tell which one is which. It's too subtle and there is no visual indication of the actual difference.
And that it doesn't matter which one I use in most cases, means I'll probably never get used to it at all. 23:41
MasterDuke i think of it that 'append', the longer one, adds more things to a list, than 'push', which is shorter and only adds one thing 23:42
Juerd MasterDuke: That's a good mnemonic at least for these. Thanks.
