Major enhancements to LLVM code generation and type handling: 1. String Operations: - Added StringBox length fast-path (length/len methods) - Converts i8* to handle when needed for len_h call - Consistent handle-based string operations 2. Array/Map Fast-paths: - ArrayBox: get/set/push/length operations - MapBox: get/set/has/size with handle-based keys - Optimized paths for common collection operations 3. Field Access: - getField/setField implementation with handle conversion - Proper i64 handle to pointer conversions 4. NewBox Improvements: - StringBox/IntegerBox pass-through optimizations - Fallback to env.box.new when type_id unavailable - Support for dynamic box creation 5. Documentation: - Added ARCHITECTURE.md for overall design - Added EXTERNCALL.md for external call specs - Added LOWERING_LLVM.md for LLVM lowering rules - Added PLUGIN_ABI.md for plugin interface 6. Type System: - Added UserBox type registration in nyash_box.toml - Consistent handle (i64) representation across system Results: More robust LLVM code generation with proper type handling 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>

# Nyash Project – Changelog (Work in progress)
|
||
|
||
This changelog tracks high‑level milestones while Core MIR and Phase 12 evolve. For detailed per‑file history, see git log and docs under `docs/development/roadmap/`.
|
||
|
||
## 2025‑09‑06
|
||
- Core‑13 flip complete: code/tests enforce Core‑13 minimal kernel. Normalizations (Array/Ref→BoxCall, TypeCheck/Cast/Barrier/WeakRef unification) are ON by default via env (NYASH_MIR_CORE13=1). New tests validate normalization.
|
||
- Docs synced: step‑50 marked done; DEV quickstart points to Core‑13 reference.
|
||
|
||
## 2025‑09‑04
|
||
- Phase 12.7‑A complete: peek, continue, `?` operator, lambda, field type annotations. Language reference updated.
|
||
- Phase 12.7‑B (basic) complete: parser‑level desugaring for `|>`, `?.`, `??`, `+=/-=/*=/=`, `..` behind `NYASH_SYNTAX_SUGAR_LEVEL`.
|
||
- Docs: language reference and Phase 12.7 README updated to reflect basic completion; extensions tracked under gated plan.
|
||
- MIR Core migration: previously enforcing Core‑15 during transition; superseded by 2025‑09‑06 Core‑13 flip.
|
||
|
||
## 2025‑09‑03
|
||
- Nyash ABI TypeBox integration stabilized across core boxes; differential tests added; loader defaults adjusted (builtin + plugins).
|
||
|

||
|
||
Notes
|
||
- Core‑13 is canonical minimal kernel. Historical Core‑15 notes remain under `docs/development/roadmap/` for reference.
|
||
- Phase 12.7‑B desugaring is gated by `NYASH_SYNTAX_SUGAR_LEVEL`; tokenizer additions are non‑breaking.
|
||
## 2025‑09‑11 (Phase 15)
|
||
- llvm: BoxCall arm cleanup — unreachable legacy block removed; arm now delegates solely to `instructions::lower_boxcall`.
|
||
- llvm/docs: Documented LLVM lowering rules (StringBox i8* fast path, ExternCall ptr/handle selection, minimal fallback policy for string concat).
|
||
- docs: Added ARCHITECTURE.md, LOWERING_LLVM.md, EXTERNCALL.md, PLUGIN_ABI.md.
|
||
- nyrt: resolved plugin module duplication; build green.
|
||
- builder: suppressed StringBox birth (constructed in LLVM path).
