How do this effort differ from truck?

Have you looked into https://github.com/ricosjp/truck?

I get a feeling that much of the groundwork needed like CAD kernel is the same as for truck, making me think that some cooperation could be beneficial for both projects.

Hey @mattiasgronlund, good question!

I'm aware of Truck, and I've considered switching to it. I decided to not do that (yet).

A CAD kernel is a really big and important dependency for a CAD application. To a large extent, it defines what the application can be. That means choosing one is a big decision.

I'm far from an expert on CAD kernels, I'm just learning as I go. I can't fully judge whether Truck is a super-solid option that would fit all my needs, or whether I'd run into limitations sooner or later. The best way I learn is hands-on, so I decided to continue my own effort and revisit this decision at a later date. Then, I'll have a much better idea of what Fornjot needs, and will be in a better position to evaluate Truck.

Another way to reach the same point would be to dive into Truck instead, by starting to use it immediately. I can't tell which way would be better, so I chose the one that seems more fun and satisfying.

Have you considered defining an interface to your kernel that is compatible with truck, so that fornjot can be built with either?

In fact, I haven't!

This might be valuable, but I suspect that it either would be a big effort (with ongoing maintenance cost). Might be interesting to explore later, but I don't think I'll attempt this any time soon.
