03:27:22zachcarterI have a reference to a generic object being passed into a method and I need to know if it contains a field of a certain type. Is this possible?
03:27:43zachcarterkrux02 recommended getTypeImpl but I can’t figure out how to get to the fields on a ref object
03:41:17ldleworkzachcarter: Isn't that what user typeclasses are for?
03:41:21ldleworkRather than using reflection
03:41:35ldleworkYou define a typeclass that has what you require, and instead of using a generic T, you use your typeclass
03:41:41ldleworknow only types that have that field can be passed in
03:42:09zachcarterhmm sounds like maybe that would work for my use case
03:42:54zachcarterthank you Idlework I’ll check them out

03:49:45zachcarteractually Idlework: thinking about it more it’s not exactly what I want
03:50:08zachcarterbut doing what I’m doing might also be a bad idea…
03:50:32ldleworkwhy isn't a typeclass what you want
03:50:40ldleworkbecause you don't always want the field?
03:50:41zachcarterwhat I was trying to accomplish is allowing the user to potentially have that field defined on the generic object
03:50:43zachcarteryeah exactly
03:50:51zachcarterbut that might not be such a great thing to do either :/
03:50:57ldleworkhave an overload that takes types that don't have the field
03:51:08ldleworknim will use the right one based on the passed in type
03:51:11zachcarterah good call
03:51:15zachcarterthank you :D
03:51:21ldleworkother thing I think
03:51:24zachcartermmhmm
03:51:29ldleworkis that you can use T as your generic discriminator
03:51:39ldleworkbut then inside, do a type switch case or whatever
03:51:39zachcarterokay
03:51:43zachcarterright
03:51:45ldleworkon the typeclass that requires the field
03:51:54ldleworkbut maybe I'm thinking of golang
03:51:57ldleworkI'm sure nim can do it too
03:52:15zachcarterokay I’ll try both and see what works best thank you for that advice, much appreciated sir
03:53:07ldleworkdom96: is there a way to install a nimble package from a local git repo?

15:57:00zachcarterbut I realize that’s not the case
15:58:03flyxno, it just puts the code snippets together. I wrote it to be able to have the snippets all in own files so I can test them on travis
15:58:19zachcarterah okay

16:21:56Serenitori noticed that the generated C can differ depending on the host-os. i feel like it should only matter what the target-os is though. can we do anything about that?
16:21:56Serenitorreason being, currently i have code that runs fine when I compile Nim -> via Linux -> C -> via Windows -> Executable, but crashes when Nim -> via Windows -> C -> via Windows -> Executable. :(
16:23:23TiberiumSerenitor, maybe you can try to compile with vcc?
16:29:38*Trustable joined #nim
16:32:02Serenitori'm new to vcc, so checking that now, thx Tiberium
16:32:37TiberiumSerenitor, if you want native windows compilation, you should always compile your programs on Windows with VCC (it's Visual Studio compiler)
16:33:52Serenitorah, that one's been called msvc or cl in my book, so many different names..
16:37:35TiberiumSerenitor, if you've installed it and you've opened special visual studio command prompt, you can use it like this: "nim c --cc:vcc program.nim"
16:48:25*nsf joined #nim
16:49:27SerenitorTiberium, all i'm aware of is how to open a prompt with access to the cl command
16:49:39Serenitorwhich would be something like: call "C:\Program Files (x86)\Microsoft Visual Studio\VC\vcvarsall.bat"
16:49:44Tiberiumyeah
16:49:49TiberiumSerenitor, you need exactly this :)
16:50:18Serenitorgreat. though i'm getting "Requested command not found: 'vccexe.exe ..."
16:50:25Tiberiumyou need to build it
16:50:35TiberiumSerenitor, navigate to folder where you built Nim
16:50:36Tiberiumand run
16:50:40Tiberiumkoch tools
16:50:52Tiberiumit will build some tools including vccexe.exe

17:08:45Serenitorthx Tiberium, though I'm still getting the same issue with vcc. seems like the worm really is in the Nim->C compilation, and not in C->Binary.
17:09:11TiberiumSerenitor, hmmm, I don't know... I compiled Nim using mingw-w64 and then used vcc to compile my programs
17:14:15dom96Tiberium: awesome, thanks :)

23:43:39ldleworkzachcarter: I wish I knew a little more about frag as to know whether to use it for nimsynth
23:43:54zachcarterIdlework maybe I can help answer questions
23:44:06zachcarterI’m working on docs at the moment, but they’re not quite close enough to being ready
23:44:43ldleworkzachcarter: we'd need to retain our fast pixel drawing style
23:45:05zachcarterokay that could potentially be done
23:45:39ldleworkzachcarter: if we wrote something on frag, how hard are we talking to get that same thing running on the web on the js backend?
23:45:41zachcartercurrently the sprite batch I’ve written discards draw data per frame
23:45:55ldleworkI know that's a ways off
23:46:01zachcarterso we’d have to make a retainedspritebatch which wouldn’t be a big deal - or something similar
23:46:03ldleworkBut I get the impression you've thought about it
23:46:31zachcarterWe were actually talking about that more today - and I think we may be bumping it up on the radar since it seems a lot of folks like having support for it especially for prototyping / sharing prototypes
23:46:40zachcarterit’s something I could start looking into this week
23:46:58zachcarterIdeally we’re supporting webassembly if possible and I think it should be
23:47:09zachcarterthe web js backend I’m not sure of
23:47:16ldleworkwhat's driving development on this?
23:47:21ldleworkfrag as a whole I mean
23:47:54zachcartermostly the community and lack of a solid cross platform 2d game framework that isn’t using the SDL2 renderer
23:48:23ldleworkah so there isn't some other thing you're working on, that you're building frag out of nessecity for?
23:48:31ldleworkJust curious is all
23:48:50zachcartersure - I do have a game that I was working on however I’d need to port a lot of code to Nim in order to continue working on it
23:49:07ldleworkWhat if you helped us with nimsynth?
23:49:11zachcarterbut it’s more out of a desire to build something others can use and I can use in future projects
23:49:19ldleworkIt wont use all the fancy features of frag, but it could focus the core
23:49:25ldleworkRight
23:49:47zachcarterthat’s definitely something that could potentially be worked out. My plan for frag for the near future was this -
23:49:48ldleworkBut perhaps our tiny scope makes the idea of working with us attractive
23:49:59*libman joined #nim
23:50:16ldlework(and could give you a reason to cover the audio api's too)
23:50:16zachcarterget documentation to where it needs to be for someone to clone / install the project within the next week or so
23:50:27ldleworkgood idea
23:50:43zachcarterand then when I get the first couple of users, work to support their projects
23:50:53zachcarterso I could technically I think work hand in hand with you guys and still be adding value to frag
23:51:04ldleworkzachcarter: we're currently using this: https://github.com/ftsf/nimsynth/blob/master/src/pico.nim
23:51:37ldleworkyeah..
23:51:50zachcarteryeah you could potentially do a lot of this already with frag
23:51:52*Serenitor quit (Ping timeout: 260 seconds)
23:51:59ldleworkI guess its based off this, http://www.lexaloffle.com/pico-8.php
23:52:15ldleworkwhich is cool...
23:52:26zachcarteryeah I’ve seen ftsf’s project it’s quite neat
23:52:41zachcarterand that pico-8 project is as well
23:53:09zachcarterso for audio, frag is using : https://github.com/yglukhov/sound
23:54:04ldleworkI assume that would allow us to do the kind of audio we're doing?
23:54:12ldleworkprocedural audio
23:55:10zachcarterhmm is there example code of the procedural audio in the link source you shared?
23:57:55zachcarterI think sound’s capabilities are fairly limited, but it does wrap OpenAL which is quite capable so I’m guessing we could expose more of OpenAL and get you what you need

23:58:01zachcarterthanks
