What does HackerNews think of NimForUE?
Nim plugin for UE5 with native performance, hot reloading and full interop that sits between C++ and Blueprints. This allows you to do common UE workflows like for example to extend any UE class in Nim and extending it again in Blueprint if you wish so without restarting the editor. The final aim is to be able to do in Nim what you can do in C++
But Nim has a pretty solid standard library with clearly written code and an awesome community to help with problems. I generally read a lot of standard library code to expand my knowledge of language and discover common patterns which repeat themselves in a lot of real world problems.
C inter-op is really first class, and as far as i know it has one of best C++ inter-op as well, you can take a look at: https://github.com/jmgomez/NimForUE for a real world example.
I use Nim for my work in both professional and personal capacity and also have written about some of it at https://ramanlabs.in/static/blog/index.html
Nim has excellent C++ FFI. It's not perfect, but capable of wrapping C++ templates, calling constructors, and virtual methods. Though it can be a pain dealing with inner template types and consts. Here's a larger example of C++ interfacing with Unreal Engine: https://github.com/jmgomez/NimForUE
