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 (ternary, sugar; peek → match に統合):
- 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
- Match Expression (pattern matching): see the Language Reference and EBNF (peek was replaced by match)
Statement separation and semicolons
- See: reference/language/statements.md — newline as primary separator; semicolons optional for multiple statements on one line; minimal ASI rules.
Imports and namespaces
- See: reference/language/using.md —
usingsyntax, runner resolution, and style guidance.
Variables and scope
- See: reference/language/variables-and-scope.md — Block-scoped locals, assignment resolution, and strong/weak reference guidance.
- See: reference/language/lifecycle.md — Box lifetime, ownership (strong/weak), and finalization (
fini) SSOT.
Type system (SSOT)
- See: reference/language/types.md — runtime truthiness,
+/compare/equality semantics, and the role/limits of MIR type facts.
Grammar (EBNF)
- See: reference/language/EBNF.md — Stage‑2 grammar specification used by parser implementations.
- Unified Members (stored/computed/once/birth_once): see reference/language/EBNF.md “Box Members (Phase 15)” and the Language Reference section. Default ON (disable with
NYASH_ENABLE_UNIFIED_MEMBERS=0).
Member exceptions and handlers (Stage‑3)
- Postfix
catch/cleanupmay be attached to computed/once/birth_once/method blocks when Stage‑3 is enabled. Stored members (plainname: Type [= expr]) do not support handlers.

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 (match (replaces peek), ternary, null‑safe).
