00:42 <oprypin> mattrberry, not crimgui but crystal-imgui 😬

00:42 <oprypin> the other one didn't get as far along as mine

00:44 <oprypin> mattrberry, it works with anything ofc but i have looked only into sfml. perhaps simply binding this lib would just make it work? https://github.com/Tyyppi77/imgui_sdl

00:50 <oprypin> what is even going on here lol https://github.com/ocornut/imgui/blob/master/examples/example_sdl_opengl3/main.cpp

06:09 <FromGitter> <mattrberry> Ah nifty, well I'll look into it sometime! I'd be curious about adding a debugger to CryBoy

06:10 <FromGitter> <mattrberry> If that works, I'll probably also use it for the gba emulator I'm working on now :)

07:11 <FromGitter> <mattrberry> Hey all, I've just pushed my first really experiment with macros to github. I call it bitfield (https://github.com/mattrberry/bitfield), and it's essentially a macro for defining fixed-length bitfields in crystal. I'd love for some feedback, since I'm sure there's still a *lot* for me to learn about macros. One thing I'm currently missing that I'd love to add support for would be custom getters/setters on

07:11 <FromGitter> ... the inheriting classes, but I don't think that's currently possible in my implementation given the fact that I define the methods on the inheriting class in the `finished` macro. Otherwise, I'm debating moving from classes to structs, but I want to run some performance tests first, so I'm leaving it as is for now

07:12 <FromGitter> <mattrberry> I also still need to add a version file

11:38 <FromGitter> <riffraff169> shards.yml still has your-name-here as author....

11:40 <FromGitter> <riffraff169> interesting, i havent needed to use macros yet (still a new crystal coder)....your module is all macros...

12:37 <FromGitter> <Blacksmoke16> they have their uses

15:32 <FromGitter> <mattrberry> Ty 👍

15:50 <oprypin> @mattrberry: are you happily using sdl at the moment? which shard?

15:52 <oprypin> i will probably want to figure something out for sdl anyway. make sure to poke me for any question; the questions will be useful for me too, to see what's missing

15:53 <FromGitter> <mattrberry> I'm using yabaddaden's sdl shard. It's missing a lot, but I've added some more bindings just in my own repo. I've debated someday trying to parse the sdl library to generate bindings

15:53 <oprypin> well i wouldn't do it any other way 😊 sfml and imgui are generated

16:01 <oprypin> sdl is probably a lot more of a challenge

16:04 <FromGitter> <mattrberry> Iirc people generate the bindings dor other languages, so I may be able to take some inspiration from those

16:05 <FromGitter> <mattrberry> I haven't really looked into it yet though because I've managed to get just enough to work for my needs

16:16 <FromGitter> <mattrberry> Gotta love manually expanding the macros lol https://github.com/mattrberry/CryBoy/blob/2fe44aeef582a403d5a7ceece64fe3a2e23bec7e/src/cryboy/display.cr#L7

17:46 <FromGitter> <asterite> oprypin: https://carc.in/#/r/9qt7

17:47 <FromGitter> <asterite> also https://carc.in/#/r/9qt9 (a bit hacky)

17:49 <FromGitter> <Blacksmoke16> :thinking:

18:14 <oprypin> O_o

18:14 <oprypin> that.. will be helpful for me

18:14 <oprypin> thanks

18:14 <FromGitter> <Blacksmoke16> looks like a good place for a comment :S

18:15 <oprypin> 😂

18:34 <riffraff169> so if you call f on the class it calls the macro, but on an instance it is a method...weird

18:35 <FromGitter> <Blacksmoke16> its not an instance, its a var that is assigned `A.class`

18:35 <FromGitter> <asterite> The thing is, macros can only be called on class types, and they must be known at compile-time

18:36 <FromGitter> <asterite> in theory that variable is know to be a class type at compile-time, but the compiler doesn't care: it will only invoke a macro if it's an explicit type, like Foo or Bar, never a variable

18:36 <FromGitter> <asterite> (or any other expression, that's why with parens it also calls the method)

19:12 <FromGitter> <riffraff169> ah, ok, hmmm...

19:51 <oprypin> i really like it. https://github.com/oprypin/crystal-imgui/commit/55b3ab7a55a8fd75b2841827d603ff5104095d86 . thanks @asterite. cc @Blacksmoke16

19:54 <FromGitter> <Blacksmoke16> neat

21:22 <FromGitter> <Blacksmoke16> made an update to my WIP validation shard. Can now define the constraints in code versus using annotations ⏎ ⏎ ```code paste, see link``` [https://gitter.im/crystal-lang/crystal?at=5f6a6b19f41f4105e4cf0e20]

23:09 <deimos_> unexpected side effect from coding in crystal, my ruby code is getting much better because i handle the Nil case by default, rather than waiting for runtime errors

23:52 <FromGitter> <mattrberry> I've recently started to write some Ruby at work, prior to which I've never used Ruby. It was pretty easy to pick up thanks to Crystal :)
