Lean 4 fork for HoTT-compatible kernel extensions (Path types, transport, HITs). Maintained against upstream leanprover/lean4.

Motivation: see "Other goodies" section at https://github.com/leanprover/lean/wiki/Refactoring-structures We had to add a new transparency mode: Instances at type_context. In this mode, instances and reducible definitions are considered transparent. The new mode is used in the defeq_canonizer, code generator, and sizeof lemma generation at inductive_compiler. We also use the new mode in the unfold tactics. |
