Does not compile with Nim 2.0.0

[simjnd]

When trying to compile the basic example project after following all the instructions, I get the following errors:

Yeah, compiling using Nim 2.0 is not supported/tested yet. I'd like to update the bindings to properly support Nim 2.0 soon, but in the meantime you can try downgrading your Nim version.

[simjnd]

Yes I saw the README mentioning it was untested so I wanted to report on it being effectively not working as of now. Thanks for the update!

[Nycto]

For documentation, I updated the github workflow to add Nim 2 support -- you can see the failures here:

I'm seeing similar issues on Nim 1.6.14 and Nimble 0.14.2 (from Nixpkgs):

It builds fine for the device. I initially tried Nim 2.0 but then I found this thread and downgraded - I even removed ~/.nimble to clear the previously downloaded playdate dependency.

I'm following the README instructions to run the hello world. What could I be missing?

@Nycto the ci run results have expired. But seems like what's required is to implement the memory manager for Nim 2. Anyone got plans to do that? Would definitely be nice to support Nim 2.

The official nim extension for vscodde requires some manual work to get going under Nim 1.6: https://github.com/nim-lang/langserver/issues/180

[Nycto]

I've made some progress on Nim 2 support -- it seems like the amount of change required is fairly small: https://github.com/Nycto/playdate-nim/commit/nim2

You can see a build running here: https://github.com/Nycto/playdate-nim/actions/runs/7867464179

I haven't yet tested it on an actual project yet, though the example project compiles and runs.

[Nycto]

I've done some testing using my own game, and everything seems to be working just fine. But I realized that I've got the nimble develop lifecycle wrong in the workflow scripts, so I need to figure out what the actual incantation is for that.
