Lean 4 fork for HoTT-compatible kernel extensions (Path types, transport, HITs). Maintained against upstream leanprover/lean4.
439c3c5544
This PR replaces the per-level `OLeanLevel → Array α` return type of `exportEntriesFnEx` with a new `OLeanEntries (Array α)` structure that bundles exported, server, and private entries together. This allows extensions to share expensive computation across all three olean levels instead of being called three separate times. A new `computeExtEntries` function in `Environment.lean` calls each extension's export function once and distributes results across levels. `mkModuleData` accepts optional pre-computed entries, and `writeModule` uses `computeExtEntries` to compute once for all three olean parts. Extensions that previously relied on `env.setExporting` being pre-applied by `mkModuleData` now call `env.setExporting true` internally for their exported/server-level filtering, since the export function is called once rather than per-level. Extracted from #13117 to be reviewed independently. --------- Co-authored-by: Claude Opus 4.6 <noreply@anthropic.com> |
