godot-nim VS Arraymancer

Since Godot 4 is gonna change their binding system the previous Nim bindings are not gonna work and the maintainers stated that they wont adapt the bindings to Godot 4.

Another option is Nim. Looks and writes like Python but closer to C in performance. It also has static typing so I prefer it for scripting as well.

People have built a few games with the Nim Godot bindings:

There’s also an interesting project to do hot reloading using dlls:

Enu is a 3D live-programming/learning/game development environment written in Nim using Godot 3, godot-nim, and godot_voxel. I use it to run a small local coding club with a group of 12 year olds, and think it is (or at least will be) a great tool for learning to code, and for making games quickly.

It uses a python-like language, is free & open-source (MIT License), has a fantastic GUI creation system, exports to all major OS's, and produces single small binaries. You could eventually incorporate Nim as well, as there are Nim bindings for Godot.

Ant then install the bindings. And thats where I'm a bit lost even after reading Godot docs. Not sure if I'm right, but seems to be necessary to compile Godot?

Well no language is perfect, but Nim can be used in almost every domain because of it's compilation targets(C, C++, JS) and it's fast compile times(who needs interpretation when compile times are that fast!):

* Shell scripting, I still assume most people will just use Bash tho: https://github.com/Vindaar/shell

* Frontend: https://github.com/karaxnim/karax or you could bind to an existing JS library.

* Backend: For something Flask-like: https://github.com/dom96/jester or something with more defaults https://github.com/planety/prologue

* Scientific computing: the wonderful SciNim https://github.com/SciNim

* Blockchain: Status has some of the biggest Nim codebases currently in production https://github.com/status-im?q=&type=&language=nim&sort=

* Gamedev: Also used in production: https://github.com/pragmagic/godot-nim and due to easy C and C++ interop, you get access to a lot of gamedev libraries!

* Embedded: this is a domain I know very little about but for example https://github.com/elcritch/nesper or https://github.com/PMunch/badger for fun Nim+embedded stuff!

Most of the disadvantages come from tooling and lack of $$$ support.

As for gdnim, it's my framework built on top of godot-nim. https://github.com/pragmagic/godot-nim https://github.com/pragmagic/godot-nim-stub

I've renewed my enjoyment of programming through game development (an area I haven't been active in before) and had a great time implementing a Quadtree in GDScript but then the other problem of raw execution speed for any script language made that a bit disappointing as well (it worked well but was only an improvement for larger numbers). So now I'm learning Nim (which has godot-nim bindings) to be able to write really performant code in an easy way.

It is a small DSL written using macros at https://github.com/mratsim/Arraymancer/blob/master/src/array....

Nim has pretty great meta-programming capabilities and arraymancer employs some cool features like emitting cuda-kernels on the fly using standard templates depending on backend !

Nim has also a powerful deep learning library called Arraymancer. It's selling point is that you don't have to rewrite your code from research to production. It's used in various machine learning projects, but one recent one that caught my eye was https://github.com/amkrajewski/nimCSO "Composition Space Optimization"

It's worth noting that nim async/await transformation is fully implemented as a library in macros.

https://github.com/mratsim/Arraymancer 11. « Premature optimisation is the root of all evil », Donald Knuth, The art of computer Programming It would be quite useful that someone writes one with examples for all these recommendations and more ...

In particular for deep learning as bobsyourunkl already mentioned there is arraymancer on the one hand and also flambeau on the other. The latter is a Nim wrapper around libtorch (i.e. the PyTorch C++ backend). It is missing things (to be wrapped by adding a few lines) and has some rough edges, but if one needs to get stuff done, it's possible.

how are u compiling (optimization, custom compilation flags etc.?) In my case https://github.com/mratsim/Arraymancer big project compile under your 4.2s so or you have like 10k+ lines of codes with macros or you just pass some debug flags to compiler :D

We have both raw wrappers for BLAS:

https://github.com/andreaferretti/nimblas

as well as LAPACK:

https://github.com/andreaferretti/nimlapack

For an example, consider calling the least squares routine `dgelsd` in arraymancer:

https://github.com/mratsim/Arraymancer/blob/master/src/array...

wrapped up in a nicer user facing API.
