Canvas vector graphics update: rich text and path boolean operation support
I wanted to share a recent large update to https://github.com/tdewolff/canvas, which is a vector graphics library written in Go to create images, PDFs, SVGs, OpenGL, etc. using vector drawing operations. Especially I wanted to show two new exciting features:
- Pixie – A full-featured 2D graphics library for Nim
-
Processing equivalent in GoLang
https://github.com/tdewolff/canvas/blob/master/examples/opengl/main.go can draw primitves but i think it would be a bit hard to do event based animation

tdewolff/canvas: vector graphics in Go (mayor update)
canvas has a focus on using state-of-the-art algorithms regarding numerical approximations, see https://github.com/tdewolff/canvas#articles for a list of publications used in this library
I see, you'd like to specify the exact output pixel size for the rasterizers? To be honest, the floats are being multiplied and rounded, so given a set of canvas dimensions in mm and a DPMM should be fine in your case. In any case, I've opened an issue to calculate the resulting DPMM automatically to get a certain pixel width and height: https://github.com/tdewolff/canvas/issues/78
Yes! See https://github.com/tdewolff/canvas/tree/master/examples/gonum-plot for an example using gonum-plot. You should be able to plug-and-play to use the canvas library!

Nim v2.0 Released
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/
- How can I add graphics to my nim program?

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

Why I enjoy using the Nim programming language at Reddit.
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.

Is Fidget usable for implementation of 3D rendering?
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.

Ask HN: What's the best source code you've read?
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.

Nim: Curated Packages
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).

Building a simple room-based chat application in Nim (using HTMX)
> 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!

What sort of mature, open-source libraries do you feel Rust should have but currently lacks?

Nim Version 1.6 Released
Nim is the most readable language I've ever seen. I've dabbled with Go, but Nim is almost like pseudocodes+types. Highly recommend you take a like, try it out! You can use libraries like https://github.com/planety/prologue or https://github.com/treeform/pixie to create something quickly and fun(compile times are faaasst!).
And Nim does not have a mandatory GC, you can go as low-level as you want, but in case you don't want that you can choose from several great GC's(a capable soft real-time GC and Boehm for example).
What are some alternatives?
svgo - Go Language Library for SVG generation
gg - Go Graphics - 2D rendering in Go with a simple API.
tiny-skia - A tiny Skia subset ported to Rust
generative-art-in-go - A companion source code repository to the book "Generative Art in Go"
go-cairo - Go binding for the cairo graphics library
godot-nim - Nim bindings for Godot Engine
Nim - Nim is a statically typed compiled systems programming language. It combines successful concepts from mature languages like Python, Ada and Modula. Its design focuses on efficiency, expressiveness, and elegance (in that order of priority).
bgracontrols - 🆗 BGRA Controls is a set of graphical UI elements that you can use with Lazarus LCL applications.
resize - Pure golang image resizing
imaginary - Fast, simple, scalable, Docker-ready HTTP microservice for high-level image processing
imagick - Go binding to ImageMagick's MagickWand C API
