Implemented a transpiler following the REVISED_STRATEGY.md approach: - Converts W language code to idiomatic Rust source code - Leverages Rust's compilation process for safety guarantees - Maps W types directly to Rust stdlib types Key Features: - Function definitions with type annotations (Square[x: int] := x * x) - Function calls with nested composition - List support (List → Vec) - Map support (Map → HashMap) - Binary operations (arithmetic, comparison) - Proper type inference and return type generation - PascalCase → snake_case naming conversion - Debug formatting for complex types Implementation Details: - Added peek_token() to lexer for lookahead parsing - Fixed := token recognition in lexer - Unified function call/definition parser with disambiguation - Proper expression vs statement generation - Automatic main() wrapper for standalone expressions Examples: - hello_world.w: Basic Print functionality - list_example.w: Vec generation and debug printing - arithmetic.w: Binary operations - multiple_args.w: Multiple function arguments - function_def.w: Function definition transpilation See TRANSPILER_DEMO.md for complete documentation and examples.
Implements full set of Rust primitive types following Rust's defaults: - Integer literals now default to i32 (not i64) like Rust - Float literals default to f64 like Rust - Support for all Rust integer types (i8, i16, i32, i64, i128, isize) - Support for all Rust unsigned types (u8, u16, u32, u64, u128, usize) - Support for both f32 and f64 floats - Backward compatible type names (int→i32, float→f64) Changes: - Updated AST Type enum with 20+ primitive types - Enhanced parser to recognize all type keywords (Int8, UInt32, etc.) - Fixed lexer to parse identifiers with digits (UInt8, Int64, etc.) - Updated code generator to map all types correctly - Changed Expression::Number from i64 to i32 - Updated Token::Number from i64 to i32 - Enhanced documentation with complete type mapping table Examples added: - types_demo.w: UInt8 parameters - types_i64.w: Int64 usage - types_float32.w: Float32 usage - comprehensive_types.w: Working demonstration This aligns the transpiler with Rust's type system conventions and gives users fine-grained control over integer sizes.
Implements all fundamental Rust container types with generic syntax: - Array[T, N] → [T; N] (fixed-size arrays) - Slice[T] → &[T] (slice references) - HashSet[T] → HashSet<T> - BTreeMap[K, V] → BTreeMap<K, V> (sorted maps) - BTreeSet[T] → BTreeSet<T> (sorted sets) Previously only List[T] and Map[K,V] were supported. Implementation Details: - Extended AST Type enum with 5 new container variants - Enhanced parser with parse_generic_type() for generic syntax - Added expect_token() helper for cleaner parsing - Parser now handles type parameters in brackets - Array type includes size parameter (usize) - Updated code generator to map all container types to Rust Type Syntax Examples: - List[Int32] → Vec<i32> - Array[UInt8, 256] → [u8; 256] - Slice[UInt8] → &[u8] - HashSet[String] → HashSet<String> - BTreeMap[Int32, String] → BTreeMap<i32, String> - BTreeSet[Int64] → BTreeSet<i64> All type mappings verified with test examples. Documentation updated with complete container type table. Files Modified: - src/ast.rs: Added 5 new Type variants - src/parser.rs: Added generic type parsing logic - src/rust_codegen.rs: Added type mappings for all containers - TRANSPILER_DEMO.md: Updated with container type documentation Test Files Added: - examples/containers_*.w: Individual container type tests - examples/all_containers.w: Comprehensive demonstration
