Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

FreeCAD User Book (2019)
I used to like OpenSCAD for its simple approach but then I discovered SDF-based modelling with Python made possible with this neat library: [1]. This is perfect if you are a programmer that doesn't know anything about CAD-Software.

>these the the central core that understands BREP and implements the geometric operations.
I've seen people quote a good modern CAD kernal as a 100 man year project. It's probably not going to happen, maybe there's some avenue for government funding?
Alternatively Signed-Distance-Functions are pretty nice. They're not BREP, but they're a lot easier to implement, and it might be possible to shove them into a BREP-shaped hole.
Here's a signed-distance-function based CAD kernal written in a few thousand lines of python+numpy, that seems to be about as fast as openscad. Maybe faster. https://github.com/fogleman/sdf

Signed distance functions in 46 lines of Python
Excellent. You might be interested in a Python library that I wrote for generating 3D meshes (STL files) from SDFs : https://github.com/fogleman/sdf
It just uses marching cubes for triangulation but the SDFs are all numpy'd and the SDF is evaluated in batches on multiple threads so it's relatively fast.

I used the SDF repo by Michael Fogleman. Check out his website, there's a ton of useful stuff on there. He contributes a lot to the open source community and has been mentioned in r/PlotterArt before.

10 ways to get the best out of OpenSCAD
Try out fogleman/sdf[1]. It is like OpenSCAD in many ways but the distance field model gives you offsets and fillets more easily.

Holy crap, why have I not seen this before?!?!!? I was even planning to start coding something like this myself. This is awesome!
- I am planning on creating a programming language for my Informatics Bachelor Thesis. What are your ideas for such a project?

CadQuery –- A Python parametric CAD scripting framework based on OCCT
For anyone interested in this, I would also recommend checking out the [antimony project](https://github.com/mkeeter/antimony). It's a parametric modeling program, but you can also pretty easily produce new scripts for its visual nodes.
