Lean 4 fork for HoTT-compatible kernel extensions (Path types, transport, HITs). Maintained against upstream leanprover/lean4.
Improves a number of elements related to Git checkouts, cloud releases, and related error handling. * On error, Lake now prints all top-level logs. Top-level logs are those produced by Lake outside of the job monitor (e.g., when cloning dependencies). * When fetching a remote for a dependency, Lake now forcibly fetches tags. This prevents potential errors caused by a repository recreating tags already fetched. * Tweaked Git error handling to hopefully be more informative. * The builtin package facets `release`, `optRelease`, `extraDep` are now caption in the same manner as other facets. Previously, they were attempting to be too clever. * `afterReleaseSync` and `afterReleaseAsync` now fetch `optRelease` rather than `release`. * Added support for optional jobs, whose failure does not cause the whole build to failure (and made `optRelease` such a job). Closes #4302. |
