Lean 4 fork for HoTT-compatible kernel extensions (Path types, transport, HITs). Maintained against upstream leanprover/lean4.
@Kha I am also tracking `currNamespace` and `openDecls`. BTW, I also tried an experiment where I added `currNamespace` and `openDecls` to `Meta.Context`, but it looked weird. This information is only needed in the elaborator and pretty printer. The `PPContext` object should contain everything you need. You can put `currNamespace` and `openDecls` in the `Delaborator.Context`. |
