NimNX

Basic nim template for skipping all the "how-tos" straight to a working example!

This project can also be used to start new NX projects. Feel free to skim through the code and see how it works.

Usage

Step #0: install nim :D

First, install devkitpro (and export env vars too).

Then, build your *.nro:

nimble install
switch_build src/nimNx.nim

Copy build/nimNx/nimNx.nro to /switch/nimNx/.

Launch using Switch

Description

This project consists of two parts:

C FFI to get all the libNX parts available for nim (under src/NimNx)
The actual nim code that uses this stuff

This project was made using following technique:

OPEN C PROJECT
FIND DEFINITION OF C VAR / FUNC / STRUCT
IMPORT IT CORRECTLY IN NIM
USE IN A SAME MANNER

So I highly recommend finding same identifiers in original libNx C code and see how it got translated to nim.

FAQ

Why `type`s + `const` for C `enums` (like under `src/nimNx/libnx/hid`)?

Nim forum

Why specify `discardable` pragma in `importc` `proc`s?

As we mostly never use their results

Why recreating BitFlags instead of importing them?

You actually need to recreate it one way or another, as it's using #define to work with bitmaps. There's a pretty low chance it would change in future releases of libNx, so I decided to recreate them.
