A1.4: Add sugar syntax `public weak parent` ≡ `public { weak parent }`
A1.5: Fix parser hang on unsupported `param: Type` syntax
Key changes:
- A1.4: Extend visibility parser to handle weak modifier (fields.rs)
- A1.5: Shared helper `parse_param_name_list()` with progress-zero detection
- A1.5: Fix 6 vulnerable parameter parsing loops (methods, constructors, functions)
- Tests: Sugar syntax (OK/NG), parser hang (timeout-based)
- Docs: lifecycle.md, EBNF.md, phase-285a1-boxification.md
Additional changes:
- weak() builtin implementation (handlers/weak.rs)
- Leak tracking improvements (leak_tracker.rs)
- Documentation updates (lifecycle, types, memory-finalization, etc.)

# 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 — `using` syntax, 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/cleanup` may be attached to computed/once/birth_once/method blocks when Stage‑3 is enabled. Stored members (plain `name: Type [= expr]`) do not support handlers.
|
||
|
||
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 (match (replaces peek), ternary, null‑safe).
