# Phase 288: REPL mode (design-first, file-mode unaffected)
|
|||
|
|
|
|||
|
|
Status: ✅ P0–P3 complete (2025-12-25) / ⏳ 288.1 next
|
|||
|
|
|
|||
|
|
Goal: Add an interactive REPL for Nyash while keeping file mode semantics unchanged and keeping the language SSOT stable.
|
|||
|
|
|
|||
|
|
SSOT:
|
|||
|
|
- REPL spec: `docs/reference/language/repl.md`
|
|||
|
|
|
|||
|
|
## Scope
|
|||
|
|
|
|||
|
|
- CLI entry: `hakorune --repl` / `-i`
|
|||
|
|
- REPL commands: `.help`, `.exit/.quit`, `.reset`
|
|||
|
|
- Fail-Fast: undefined reads are errors
|
|||
|
|
- File mode: no behavior changes (quick smokes remain green)
|
|||
|
|
|
|||
|
|
## Completed (P0–P3)
|
|||
|
|
|
|||
|
|
- P0: SSOT doc established/updated (`docs/reference/language/repl.md`)
|
|||
|
|
- P1: CLI entry point (`--repl` / `-i`)
|
|||
|
|
- P2: REPL session state isolated (Box-first; runtime-value based)
|
|||
|
|
- P3: Minimal UX and docs polish
|
|||
|
|
|
|||
|
|
## Next (Phase 288.1)
|
|||
|
|
|
|||
|
|
The MVP intentionally deferred these:
|
|||
|
|
|
|||
|
|
- Session variable **persistence across lines** (bridge session → compilation/runtime)
|
|||
|
|
- Expression auto-display + `_` last-value binding
|
|||
|
|
- Multi-line input handling (continuations)
