Elronnd how to construct a CUnion which is nested inside of a CStruct? 03:48
ix.io/1UoN/perl6 I have this, and I can't figure out how to create a new P6Val. I mean, I can create one, but then I have no way of setting the P6Data inside, nor can I set it from the constructor 03:49

mtj hey folks, is it possible to specify a module's required version number, or greater? 06:45
use SDL2::Raw:ver(0.2);
^ ..could i set version 0.2, or greater? 06:46
jmerelo mtj: it should be possible, yes.
mtj awesome!... anyone know of an example? 06:47
docs.perl6.org/language/modules#use
ive gotten that far ^ :)
jmerelo mtj: it should be straightforward, but give me a minute 06:48
mtj: github.com/JJ/my-perl6-examples/bl...rsioned.p6 06:52
timotimo oh, cool, someone's using SDL2::Raw :) :) 06:56
mtj hi timotimo , yes. hopefully.. 06:57
jmerelo: i have a look at your example, but still dont quite understand it 06:58
i attempted to execute it, it had an error 06:59
ok, its just an example - not to be executed 07:01
jmerelo mtj: it needs to go with this: github.com/JJ/my-perl6-examples/bl...sioned.pm6 and then run with perl6 -Ilib versioned.p6, sorry 07:02
mtj jmerelo: i see your commit... github.com/JJ/my-perl6-examples/co...65be39c6e6 07:05
...and your pm6 module is set to Versioned:ver<0.0.1> 07:06
so, how do you say ver 0.0.1... and greater?
not.. 07:07
unit class Versioned:ver<0.0.1>
jmerelo mtj: you would need to say that in the client, not in the class. But I'm not sure you can. Let me just try 07:08
mtj ah, sorry, its fri 7pm here..
yes click :)
jmerelo mtj: Japan?
mtj: it's sunny and warm here in Granada, Southern Spain 07:09
mtj: but yes, right, that does not work. Versions work literally in "use", so if you say :ver<0.0.1+> it will literally look for that.
mtj: you can specify that as a dependency in META6.json, and zef will do its best to find something that accomodates your wishes. But then you need to either avoid any version or else use a specific one. 07:10
mtj ha, i was just thinking of that example ^
jmerelo: thanks for your examples repo, looks very interesting 07:11
jmerelo: hi from new zealand :) 07:12
jmerelo mtj: that's exactly the antipodes of Spain :-) 07:14
mtj: those are examples I use for the documentation, stackoverflow answers and so on... It's probably more informative if you go to any of those. But feel free to use and ask :-) 07:15

Xliff I'm getting it from the but operator... github.com/Xliff/p6-GStreamer/blob...ry.pm6#L99 10:08
jnthn You won't be able to mix into a CStruct 10:10
A but is a clone followed by a `does`
So even if the clone step worked, the `does` part ain't going to
Xliff *ARGH* 10:11
OK. Thanks, jnthn. Is there any plans on fixing that, or will that work when CStruct cloning is implemented?
Oh. The 'does' part isn't either... 10:12
jnthn The clone thing is worth doing, but maybe involves some interesting question on memory management
The `does` part is not going to be happening, probably. Or if it is, then only if you want to add methods, but there's no way to add more attributes
I mean, it's backed by a C structure 10:13
Not a P6opaque
And P6opaque has all kinds of things done to handle mixins

Remove trailing slash in exported PATH

The instructions on building from source for Linux had a trailing slash in the exported `$PATH`, which made the output of `which` ugly:
  ```
  $ which perl6
  /home/user/rakudo/install/bin//perl6
  ```
Although this is a purely cosmetic change, removing this trailing slash makes for less unexpected output.		 15:33

Doc_Holliwood It would be super cool if we could use .NET/mono classes from Perl6. Has anybody given that a serious thought? 19:03
There is this P/Invoke mechanism and you can use .NET from C/C++ so it should be possible. 19:04
netrino Does anybody have any tips on debuggin Cro::WebSocket library? I'm using library that is using websockets and on my production machine it just hangs on first `send' call and i don't know how to approach it. Tried to install different versions of perl6 to no success. I only have ssh access to production machine, so it sort of limits my options. 19:05
El_Che_ is the client side ok? E.g. when you open the browser console, can you send stuff (e.g. PING) 19:06
netrino Ah, it is used as a client on the backend 19:07
irced netrino: i dunno about the library but maybe i can help. are you attempting to make a secure (i.e. wss) websocket connection?
[Coke] bisect: say (-80538738812075974) ** 3 + 80435758145817515 ** 3 + 12602123297335631 ** 3 ; # try it with just the output.
bisectable6 [Coke], On both starting points (old=2015.12 new=9dd67cb) the exit code is 0 and the output is identical as well
[Coke], Output on both points: «42␤»
netrino irced: I think so, it is used in API::Discord library, i've been able to trace the problem down to WebSockets, let me check if it's wss 19:08
19:08 maettu left
netrino irced: Yes, it is 19:08
19:08 maettu joined
irced netrino: have you attempted to make a plain https connection from the production machine using the command line? 19:09
netrino So, to clarify, i'm talking about Cro::WebSocket::Client, not the server
[Coke] AlexDaniel: github.com/perl6/whateverable/wiki/Bisectable has an irc log link going through the party host. (near the end) 19:10
irced this is important because websocket requires an http(s) opening handshake before upgrade
netrino irced: well, curl google.com worked
AlexDaniel [Coke]: that's right… and we have to restore that 19:11
[Coke]: so the redirection worked through Zoffix's stuff, and it's currently down
irced netrino: you mentioned server. can you connect to the server via https ? (techinically you should be able to connect since again websocket is an upgrade after the https connection) 19:12
netrino irced: and Cro::HTTP::Client.get('google.com', :http<1.1>) returned me a page
irced now i am referring to the websocket server
netrino irced: I don't have a websocket server there
irced since we have established you can connnect to an known https server
netrino irced: the program that is on the server uses WebSocket as a client 19:13
irced instead of wss://SERVER can you SERVER
netrino Let me see
irced it's okay if curl doesn't find the https index page 19:15
as long as you get a response
19:15 Kaiepi joined, mowcat joined
irced i got my own side question, i want to create an infinite sequence using gather, is this possible? my first attempt is failing. 19:16
i have my $seq := gather { state $prev = 0; take ++$previous if test($previous); } # test is block code defined earlier 19:17

netrino irced: yeah, it returns 404 19:18
irced netrino: ok. have you tested Cro::WebSocket::Client with wss://echo.websocket.org ? (which can be used for simple tests) 19:19
netrino: it would be good to test with ws://echo.websocket.org as well 19:20
netrino: note that again i can't speak to Cro but be sure you are using the Cro secure websocket implementation for wss
squashable6 🍕 FCO++ edited wiki page “Dynamic Variables”: github.com/FCO/Red/wiki/Dynamic-Variables 19:21
irced because if you don't you will fail the handshake before the upgrade

19:22 SCHAPiE left
netrino I wonder if it might be related to the ssl library verseion 19:23
irced perhaps not the library version but instead that module OpenSSL may need to be installed
netrino irced: and connection succeeded with plain ws
irced another thing to which i cannot speak (but i know openssl in C)
netrino irced: OpenSSL is a depedency, it is installed 19:24
and it's the same version as on my local machine, where everything just works 19:25
irced netrino: oh
netrino different OSs tho

irced netrino: curl works and probably uses the openssl shared library but it won't hurt to make sure that libssl*so* is on the machine 19:29
netrino: and your suggestion about it being a version issue could lead you somewhere 19:31
netrino irced: everything seems to be in order. Thanks for helping me out, i'll try to dig more on this issue. But this is a bit strange. cause in my app i doesn't fail on connection, it actually receives some data from websocket server as i understand but hangs on sending. Might be not even related to SSL, i've read about some deadlock issue on cro::websocket github, but figured it probably should be the same on my 19:34
local machine too.
Just spent whole day without any success, needed some fresh perspective :)

timotimo netrino: did you already try setting CRO_TRACE in the environment?

timotimo so maybe try the latest version off of github or pass :http<1.1> in the right spot to turn http2 off 19:45
netrino Also, weirdly, i've tried again and now it doesn't complain about SSL and connection to wss works just fine
timotimo: yeah, i checked that WebSocket specifies http<1.1>
timotimo oh, i didn't know that 19:46

Xliff timotimo: If I have a CStruct with another CStruct in it via HAS. The member CStruct is not ever supposed to be a type-object, right? 23:03
SmokeMachine AlexDaniel: Done!
timotimo yeah, shouldn't
AlexDaniel SmokeMachine: yeah, it's better now!
SmokeMachine AlexDaniel: could you test it, please?
Xliff github.com/Xliff/p6-GStreamer/blob....pm6#L1365 23:04
If I run t/06-pad-caps.t, that's the error message I get.
Actually, now that I'm looking at it. Seems the whole CStruct is null.... 23:05

AlexDaniel mst: please surprise me :) colabti.org/irclogger/irclogger_lo...08-24#l233 23:08
Xliff timotimo: Almost looks like the HAS is getting ignored.

SmokeMachine: oh, so the issue editing script worked? :) 23:09
or did you just edit it all manually? :) 23:10
SmokeMachine AlexDaniel: I did try, but I'm having some problem on my mac... it was by hand... 23:11
AlexDaniel aww
SmokeMachine AlexDaniel: for some reason, my zsh was killing it...
AlexDaniel: but I was thinking on PRing this www.irccloud.com/pastebin/xVem1TdX/ 23:14
AlexDaniel SmokeMachine: sure! 23:16
SmokeMachine AlexDaniel: but I couldn't test, so I didn't... 23:17

irced how would one create a sequence to solve for two variables as in 65537x + 3511y = 1 for all integer values (including -Z and 0) as a sequence? 23:54

irced basically i need to test over two infinite ranges 23:55
timotimo given any x you get a set of ys for free 23:58
you want to "diagonalize" the space
irced feels a ping pong knocking off the insides of his skull.
timotimo imagine your x and y are coordinates, you'd be spiraling outwards from 0 through all valid values
that way you'll get a good distribution of all manner of values 23:59
irced in perl6 please
irced chuckles
timotimo nah, i'm going to bed
irced i follow you tho, thanks
