Had a look a Nim few months ago - feature wise is a lot of I wish Python had (easy interop with C/C++, static typed, compiled, can be transcompiled and executed on android/iOS), but ecosystem is small even though the language is not new. There is not many high quality libraries such a numpy, scipy, pandas, opencv in python. They lack some big player adopting it - it's too bad Unreal Engine didn't try to adopt Nim instead of creating their own new scripting language Verse.

One thing I'm also lucking is out-of-the-box interop with C/C++ libraries without creating own adapters (so that you can just import header and be done with it).

Another thing is I wish it had similar easy interop with Rust - just to increase adoption and also because in Rust easier to find high quality cross-platform crates (including mobile) that work without hassle even on mobile devices.

I worry in few years either Python will catch up (because of faster python, non-GIL, nuitka, briefcase for mobile etc) or Mojo will eat Nim lunch.

To be fair to Nim, only Python has the huge ML ecosystem of numpy, scipy, pandas, opencv, pytorch, tensorflow, keres... Doing ML/AI style work in anything but python is really hard!

That said Nim does have the nimpy library that allows for pretty seamless interop with python. Which means you can just import PyTorch, or scipy, or opencv and use them in Nim.

for me (mobile developer) interop with python is not enough because of really poor python story on mobile devices (iOS / android) when using native modules. I think if Nim had a seamless interop with Rust or even Zig it could piggyback on those communities to get some libraries for free.

For Rust at least one can use https://github.com/arnetheduck/nbindgen

That looks interesting. Unfortunately it looks like it hasn't been updated in a while? Is that because it's complete or a lack of interest?

For example, the approach mentioned at the bottom of the README of integrating via nlvm (https://github.com/arnetheduck/nlvm) sounded great but appears to be unpursued.

[pzo]

that looks interesting, thanks! Did you try it if it delivers on promises? There was not any new commit since 2020 so not sure if the project is stale by now.

I do not use Rust, so sadly I have not.

As a 2-step approach, you could also probably use https://github.com/mozilla/cbindgen and then Nim's native C FFI.

Dunno about rust, but since both Nim and Zig compile to C as interim, it should be fairly easy to get them working together, no?

[pzo]

Things might changed but last time I checked you could easily call C function but you had to kind of export each single C function, structs etc. You couldn't just import single header file and be ready to call any function in the library. There is some pending project [0] futhark but not sure how mature it is and that still only for C libraries (instead of C++ or Rust) but maybe easy adopt for Zig - would be great nonetheless.

Most of those libraries are written in C++ or C, which Nim has excellent support for. I've used opencv c++ library with Nim. It's just that opencv is so massive it'd take a lot of work to wrap well, so I haven't yet. Some folks are working on a pure Nim pandas lib too.

I found the following article about Nim and Rust interop:

Haven't read it yet but it looks promising.
