Xliff Sometimes when I cast a CStruct to a CPointer, I get "This REPR cannot change type" (which makes no sense, this has to exist for NativeCall to even work!) -- is there a workaround? 00:56

raydiak maybe I'm confused, but wouldn't you cast to Pointer, not CPointer? 01:18
m: use NativeCall; class C is repr<CStruct> { has uint8 $.a; }; say nativecast Pointer, C.new 01:20

Xliff raydiak: Yes. And for some reasons, if I do exactly what you did, I will get this message. 01:29
It might have to do with the fact that the Struct in question came from C, not Raku.
raydiak I don't think coming from C should cause it, but I could be wrong. without an example to analyze and play with, we can only blindly speculate 01:33
01:38 dcx is now known as lambdacx 01:39 lambdacx is now known as dcx
Xliff radiak: The only example I can give you is a script written off of one of my projects. 01:47
And I ahve yet to add that to Git 01:48
01:53 SmokeMachine left, SmokeMachine joined
raydiak the reasons I keep suggesting that you reduce your problem to a short example are: (A) you're much more likely to get help because it makes it easier to help you, (B) often in the process of cutting your big project down to a small example, you'll zero in on the problem yourself through bisection, and (C) if it's hard to reduce, it points to places where you ought to have cleaner separation between the 01:54
different parts of your project
02:03 Manifest0 left
raydiak either way, hopefully someone with more nativecall experience will chime in here eventually and have a guess as to what you're doing wrong :) 02:03

Xliff tonyo: NativeCall handles that automatically when dealing with C-calls. I don't think that's the issue. Working on a smaller (hah!) example. Thanks the thought. 16:41
16:50 mowcat left
tonyo nativecall does not autocast pointers to structs 16:50
or vice versa 16:51
seems you already know what the issue is, though. 16:53
Grinnz just fyi, depending on how much trust you have for the new freenode staff, you may want to re-evaluate *!*@freenode/staff/* having access flags on this channel 16:54
and you can talk to daemon if you want the bot from #perl to actively inform people as they join 16:56

raydiak Xliff: you need another proxy over data like you did with mime_type and inlined, and to run it under a modern raku instead of a 2 1/2 year old one. with the proxy it works for me on 2021.04 21:03
Xliff raydiak: Oh. You mean tio.run is using an older version? LOL! Thanks. 21:04
raydiak yes quite old. you're welcome :) 21:05
Xliff raydiak: Can you link your code? 21:07
raydiak: When you making the move to libranet?
raydiak gist.github.com/raydiak/cded4a7621...8390023ffb 21:09
I'm already there
I just copied one of your proxies, changed the names in it, and made data private. no other changes besides the indents :) 21:11
tonyo if only there was a way to shorten urls
Xliff Heee!
raydiak if you really want to keep using these browser things for running raku, you might try glot.io. I haven't used it much personally, but it's well-known, supposed to be stable, and has sane URLs. and looks like their raku is only 3 months old
Xliff ROFL. OK. 21:13
tonyo for one thing, that CUnion may or may not have an `inlined` variable
Xliff repl.it used to be the same, but they grew profitable and so ... 21:14
Thanks for your glot.io suggestion. I will look inti it.
raydiak sure thing, happy to help 21:15
I probably should have engaged that over here. saw it on freenode first, answered there. seems fixed by putting another Proxy over EPhotoDataInlined!data gist.github.com/raydiak/cded4a7621...8390023ffb 21:19
and running under a modern raku...tio.run is way back on 2018.12
