Selfhosting Dev c8063c9e41 pyvm: split op handlers into ops_core/ops_box/ops_ctrl; add ops_flow + intrinsic; delegate vm.py without behavior change
net-plugin: modularize constants (consts.rs) and sockets (sockets.rs); remove legacy commented socket code; fix unused imports
mir: move instruction unit tests to tests/mir_instruction_unit.rs (file lean-up); no semantic changes
runner/pyvm: ensure using pre-strip; misc docs updates

Build: cargo build ok; legacy cfg warnings remain as before

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.

Grammar (EBNF)

  • See: reference/language/EBNF.md — Stage2 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 (Stage3)

  • Postfix catch/cleanup may be attached to computed/once/birth_once/method blocks when Stage3 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 longform reference; use the Cheat Sheet for quick syntax lookup.
  • Phase 12.7 files capture the finalized sugar and new constructs (match (replaces peek), ternary, nullsafe).
