While I always advocate for lib wrappings to be as faithful to the originals as possible, to make it easy for people to follow their documentations, in this case I'll have to agree that at least proc names should change to lower case first letter (which doesn't make it harder to follow the docs anyway). Not out of preference of reading it's code as Nim code (I disagree with that argument, really), but because as it is it's breaking code highlighting, and you end up with procs having the same color highlighting as types (tested in Sublime and VSC). This makes the code harder to read and figure out.
I also agree with @exelotl, a nimble package would be quite handy, because it allows you to just `import raylib` from any of your modules, instead of having to keep track of where the file is located relative to them, like `import ../../raylib`.
