SVGToolpathReader VS json

Is this the correct github for setup/use instructions? https://github.com/Ghostkeeper/SVGToolpathReader

I've been trying to get this to work for a couple years now but haven't had any luck. There's a Cura plugin called SVG Toolpath Reader that I have seen applied to models that will print the first layer following the lines of the SVG image - IOW if you apply an SVG "weave" in the pattern of carbon fiber, the pinter will follow the SVG pattern as a toolpath and print the first layer in the crosshatch pattern of the weave. Looks neat! Also, you can do this for other patterns or even lettering. However, I'm stumped. The directions are pretty much "Drop the image in Cura." Ok, great...how do I apply it to a model? I'm using Sketchup, but have some familiarity with Blender and can use Meshlab, -mixer, -room. Any help would be appreciated.

I implemented an svg renderer a few years back. Due to the nature of what this code does it only needs the outline of shapes, thankfully, but MAN there are a lot of components to it. Getting the CSS to work 90% of the time was a nightmare, and I'll never reach 100% I'm sure. I never intended the code to encompass this many things so it's terribly structured. I didn't even touch Javascript since interactivity is irrelevant for my context.

I have not done a "desktop" program in 25+ years and never using C++ (or C), since then I'm mostly a web developer (PHP,Elixir, JS, Kotlin etc).

I'm currently doing a C++ audio plugin with the Juce framework.

This website has been a good resource, alongside https://www.learncpp.com

But I was actually close to give up before using those two things:

- https://github.com/nlohmann/json : my plugin use a json api backend and the Juce json implementation is atrocious (apparently because of being born in previous c++ version), but this library is GREAT.

- ChatGPT 4. I'm not sure I would have "succeeded" without it, at least not in a reasonable time frame. ChatGPT 3.5 is slow and does not give good results for my use case but 4 is impressive. And I use in a very dumb way, just posing question in the web UI. I probably could have it directly in MSVC?

Also I must say, for all its flaws, I have a renewed appreciation for doing UI on the web ;)

https://github.com/nlohmann/json works well for me

Here is one popular C++ library (nlohmann/json) removing its use.

Before going into binary serialization I suggest you to get comfortable with serialization to text. You can try to write your data to text files and read them in again. Then after you get an idea of how this works you can try to use a library that writes to XML or json, e.g. nlohmann json

Download the single header file json.hpp from https://github.com/nlohmann/json/releases and place it in your project directory or an include directory.
