Ecosystem-wise - a brief subset of Nim packages:

One can, of course, go much further than simply distinct number types: https://github.com/ringabout/awesome-nim#science

(Unchained seems maybe the most featureful of those units packages.)

> This is useful for compiler programmers, or maybe also those writing source code analyzers/optimizers, but is that it?

It is also useful for anyone wanting to implement language-level features as simple libraries. Someone else brought up Nim here: it's a great example of what can be done with metaprogramming (and in a non-Lisp language) as it intentionally sticks to a small-but-extendable-core design.

There's macro-based libraries that implement the following, with all the elegance of a compiler feature: traits, interfaces, classes, typeclasses, contracts, Result types, HTML (and other) DSLs, syntax sugar for a variety of things (notably anonymous functions `=>` and Option types `?`), pattern matching (now in the compiler), method cascading, async/await, and more that I'm forgetting.

Just under their table of contents, they say that "This list is fairly outdated." and point you to https://github.com/xflywind/awesome-nim - and that repo seems to have recent updates.

Thanks for making these, I actually had no idea these existed! I don't "need" them now but seeing these gives me ideas for projects and makes future things easier.

I wish discovery of community libraries was higher, I'm constantly discovering libraries that do amazing things 'hidden' away. I know there's https://nimble.directory/ and https://github.com/xflywind/awesome-nim but most of the time I end up using a search engine for something specific if I think of it.

We have written pixie: https://github.com/treeform/pixie . Pixie is a 2D graphics library similar to Cairo and Skia written entirely in Nim. Which I think is a big accomplishment. It even has python bindings: https://pypi.org/project/pixie-python/

I made it because I really like pixie/boxy/windy combo, but there is no gamepad support built-in.

With Nim, you can continuously optimize and improve the hot spots in your code. For example, in the Pixie graphics library, path filling started with floating point code, switched to floating point SIMD, then to 16-bit integer SIMD. Finally, this SIMD was written for both x86 and ARM.

The author Fidget actually has a number of other great libraries that are part of the rendering stack. Notably, Pixie for text and shape rendering in 2D, Boxy for rendering textures to the GPU via opengl, and then Windy for an OS window context and user events, and a number of other libraries related to 3D rendering.

Perhaps not the "best" source code I've ever read, but libVF.io had some beautiful code for what's generally gnarly system-glue code. The iommu setup code is a good example and inspires me to think that system-glue code doesn't need to be gross or impenetrable: https://github.com/Arc-Compute/LibVF.IO/blob/master/src/libv...

Another one I've appreciated reading (and learned more about 2d graphics from) is Pixie, a 2d graphics library written in Nim. Here's the implementation of a fair subset of SVG paths: https://github.com/treeform/pixie/blob/master/src/pixie/path...

And one last one for basic algorithms: https://github.com/nim-lang/Nim/blob/version-1-6/lib/pure/al...

Of course Knuth's original code is still some of the best classic code. K&R's original C book is a classic.

I recently helped work on a new open source JPEG decoder in Nim. (Over here on GitHub: https://github.com/treeform/pixie/blob/master/src/pixie/file...)

This video was extremely helpful to understand the "why" of all the things the spec was trying to explain. It made a huge difference in us being able to get things working.

We talk a bit about JPEG and actually writing our decoder in Nim here: https://www.youtube.com/watch?v=vYwD7OynFcg

Overall, our concluding opinion is that JPEG has some extremely cool and really smart ideas for how to compress images but the binary file format itself has some very painful things in it (progressive and restart markers as a couple examples).

I am working on OpenStreetMap renderer in Nim - see https://github.com/severak/lunarender3/ (but work somewhat stalled)

I needed some language which is:

- compiled to binaries

- and really fast

- has needed libraries (HTTP server, protocol buffers, sqlite and image generation)

- it's easy to set up

It was nice experience and Nim simply worked for my needs. People on Nim forum were nice and helped me when I ran into problems. It has nice and usable built-in library and I was really impressed by graphic library pixie - https://github.com/treeform/pixie

I would use Nim again when I when I will see this application is suited for it (e.g. some command line apps).

> but not so small that there are no useful libraries written...

Says the person responsible for a ton of really useful, well-done Nim libraries, such as this amazing Cairo/Skia-like library: https://github.com/treeform/pixie#readme

Thank you for all the things you've made for Nim!
