Module parser 

Hand-written recursive-descent parser for Bynk v0.

Token grammar in spec §4. The expression parser uses one function per precedence level (§4.4). Errors carry spans and short fix-oriented messages; the parser does not currently attempt synchronisation, which means at most one parse error is reported per compilation.

Functions

parse

Parse a token slice into a Commons AST.

parse_unit

Parse a token slice into a SourceUnit — either a commons or a context.

parse_unit_with_recovery

Parse a token slice into a SourceUnit with error recovery, returning a best-effort partial AST plus the full list of parse errors and warnings.

parse_units

Parse a token slice into all the top-level SourceUnits in one file (v0.113, testing track slice 1b). A .bynk file may hold more than one top-level declaration — an atomic file with commons/context and a suite together (DECISION S) — so the compiler parses a Vec, not a single unit. Test-ness is a property of each declaration, not of the file.
