Reading files with pathlib

[paddyroddy]

Have to convert to string before reading in

[teseoch]

Interesting, I have no idea how to fix this. Seems more of an issue in pybin11 than igl

[paddyroddy]

in the code I just convert it to a string which works i.e. I pass in str(_meshes_path / f"{mesh_name}.obj") in this example

My understanding is that the implicit feature request here is for igl.read* (and igl.write*) functions to accept pathlib paths as input in addition to strings. Sounds like a good request and would be happy to merge a PR if anyone wants to take it on.

Yep, that's what I was thinking!

I think this means that the underlying C++ function in libigl should probably take std::filesystem::path as input.

If I read that page correctly then std::filesystem::path is convertable to string as well. So maybe we could already start with using std::filesystem::path as the input type on the bindings.
