You can do a lot with Nim at compile time, check out my talk on Nim Metaprogramming not just for FizzBuzz, but real world applications: https://fosdem.org/2022/schedule/event/nim_metaprogramming/ I am working an a macro to compile Nim code into GLSL. So not only can you write Nim to C or Nim to JS, it can also (in limited way) do Nim to GLSL GPU Shaders. See here: https://github.com/treeform/shady I am also working on a macro system similar to SWIG, where using a some macros one can write a Nim library and generate wrappers for your NIM library for many languages like C, Python, JS, Ruby. See here: https://github.com/treeform/genny

Also of interest for people might be Genny. It’s a Nim library to automate creating language bindings for other languages. Currently it supports Python, Node, and C. https://github.com/treeform/genny

For those using Python, we just got our Python bindings for Pixie up onto pip. Repo here https://github.com/treeform/pixie-python It's extremely fresh but our tests are working so consider giving it a try. For those interested in Nim's meta-programming, we're generating those Python bindings for Pixie from our Nim code using https://github.com/treeform/genny here https://github.com/treeform/pixie/blob/master/bindings/bindi... More languages in the works.

Dlang's betterC would be a good option for just a better-than-C language but looks like it doesn't support D's standard library [1]. That'd mean being stuck with plain C container libraries. :/ Personally, I was impressed by an approach taken by the authors of Pixie (a fast 2d library like Cairo) [2]. They created a "library wrapper" generator for Nim code that supports creating libraries Python, Node, C, and Nim itself that they call Genny [3]. Haven't tried it but being able to use Nim and it's ref based gc but still export to nice API's in other languages is fantastic. Pixie's aim is to be a Cairo alternative so it makes sense they'd need this. I hope the approach takes off. Usually writing any cross language API's is a lossy operation. Here's a sample of the API definition: exportObject Matrix3: constructor: matrix3
