Lean 4 fork for HoTT-compatible kernel extensions (Path types, transport, HITs). Maintained against upstream leanprover/lean4.
This PR adds the pre-stage0-update infrastructure for named error messages. It adds macro syntax for registering and throwing named errors (without elaborators), mechanisms for displaying error names in the Infoview and at the command line, and the ability to link to error explanations in the manual (once they are added). |
