Consider porting to a language that doesn't require a runtime #34

Open arilotter opened 1 week ago

In contexts where you don't require a Python install for other things, including nix-gl-host drags along of python 3 as a ~100mb bump in size.

For example - I have a Rust program that I package into a Docker image, and nix-gl-host ups that image size by 100mb due to its Python dep. I've ported nix-gl-host to Rust here https://github.com/arilotter/nix-gl-host-rs and it seems to work perfectly!

Is that project really working? I've tried to -p option work( https://github.com/arilotter/nix-gl-host-rs/pull/1 ) but it's just clearing old nixglhost's cache.

Also is the footprint of python nix-gl-host large? I've calculated size of my cache(cuda+gl drivers) but it's far more large:

du -sh ~/.cache/nix-gl-host/
3.1G    ~/.cache/nix-gl-host/

And is rust with libc runtime free? You're using patchelf that also requires libc

Nice! Porting this to Rust was indeed part of our roadmap!

I sadly don't have any Nvidia GPU anymore to test this :( (See https://github.com/numtide/nix-gl-host/issues/7#issuecomment-1704905762 for more details)

If anybody's willing to take over this project to push it forward, we could definitely move this to nix-communiy and add new maintainers to it.

Ping @Atry @wentasah @SomeoneSerge who also expressed some degree of interest for this project in the past as well.

ah nice catch, I mis-implemented -p. will fix. it does seem to work for wrapping executables, it lets me run a Nix CUDA application in an Ubuntu docker image :)

Also is the footprint of python nix-gl-host large?

it's about 100mb. I'm golfing all my dependencies down in size and this one seemed easy to tackle.
