I agree, that’s also pretty much why Starlark exists. However, there are many cases where you do need complex build logic. Personally, I always go for declarative CMake first, then waf as soon as I find my CMakeLists looking like something other than just a list of files. I’ve considered before creating a simple declarative language to build simple projects like that with waf, but I don’t like the idea of maintaining my own DSL for such little benefit, when CMake works just fine, and everyone knows how to use it. I feel like I’d end up with my own little TempleOS if I decided to go down that rabbit hole.
