Lean 4 fork for HoTT-compatible kernel extensions (Path types, transport, HITs). Maintained against upstream leanprover/lean4.
The new Lake build monitor is now more selective, accurate, and prettier in what it prints. **Key Changes:** * Poll jobs at a fixed frequency (100ms), updating the caption and finished job count. * Add `action` field to jobs to record information about what jobs do. It enables distinguishing between jobs which build something, fetch from a store, or reload logs from the cache. * At standard verbosity, print build captions only when a job is know to build or fetch something (i.e., `action >= .fetch`). * Add an icon and color to job captions based on their log-level / build status. Also add color to levels in logs. * Add `--ansi`/`--no-ansi` to toggle Lake's use of ANSI escape codes. * Fix some `v4.8.0-rc1` bugs and `--old`. Closes #2822. |
