Selfhosting Dev af11c6855b 🚀 Start Phase 15.3: Nyash compiler MVP implementation 
Major milestone:
- Set up apps/selfhost-compiler/ directory structure
- Implement basic Nyash compiler in Nyash (CompilerBox)
- Stage-1: Basic arithmetic parser (int/string/+/-/*/括弧/return)
- JSON v0 output compatible with --ny-parser-pipe
- Runner integration with NYASH_USE_NY_COMPILER=1 flag
- Comprehensive smoke tests for PHI/Bridge/Stage-2

Technical updates:
- Updated CLAUDE.md with Phase 15.3 status and MIR14 details
- Statement separation policy: newline-based with minimal ASI
- Fixed runaway ny-parser-pipe processes (CPU 94.9%)
- Clarified MIR14 as canonical instruction set (not 13/18)
- LoopForm strategy: PHI auto-generation during reverse lowering

Collaborative development:
- ChatGPT5 implementing compiler skeleton
- Codex provided LoopForm PHI generation guidance
- Claude maintaining documentation and coordination

Nyash Language Reference – Index

This is the entry point for Nyash language documentation.

  • Full Language Reference (2025): reference/language/LANGUAGE_REFERENCE_2025.md
  • Syntax Cheat Sheet: quick-reference/syntax-cheatsheet.md
  • Phase 12.7 Grammar Specs (peek, ternary, sugar):
    • Overview: development/roadmap/phases/phase-12.7/grammar-specs/README.md
    • Token/Grammar: development/roadmap/phases/phase-12.7/ancp-specs/ANCP-Token-Specification-v1.md
  • Sugar Transformations (?., ??, |> and friends): parser/sugar.rs (source) and tools/nyfmt/NYFMT_POC_ROADMAP.md
  • Peek Expression Design/Usage: covered in the Language Reference and Phase 12.7 specs above

Statement separation and semicolons

  • See: reference/language/statements.md — newline as primary separator; semicolons optional for multiple statements on one line; minimal ASI rules.

Related implementation notes

  • Tokenizer: src/tokenizer.rs
  • Parser (expressions/statements): src/parser/expressions.rs, src/parser/statements.rs
  • MIR Lowering (expressions): src/mir/builder/exprs.rs and friends

Navigation tips

  • The “reference/language/LANGUAGE_REFERENCE_2025.md” is the canonical long‑form reference; use the Cheat Sheet for quick syntax lookup.
  • Phase 12.7 files capture the finalized sugar and new constructs (peek, ternary, null‑safe).
