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 types + const for C enums (like under src/nimNx/libnx/hid)?

Nim forum

Why specify discardable pragma in importc procs?

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.
