New supported language constructs include: - Union declarations and their members - Destructors and their implementations - Operator overloading (including stream operators) - Free-standing and namespace-scoped functions - Enum declarations (both traditional and scoped enum class) - Lambda expressions and their captures - Attributes and annotations - Method overrides with virtual/override specifiers - Exception specifications (noexcept) - Default parameters in function declarations - Variadic templates and parameter packs - Structured bindings (C++17) - Inline namespaces and nested namespace declarations - Template specializations and instantiations - Constructor implementations This enhancement provides more comprehensive code structure analysis for C++ codebases, particularly those using modern C++ features from C++11, C++14, and C++17 standards.

Added support for struct and interface definitions with proper type identification - Implemented parsing for constant declarations (both single and in blocks) - Added support for variable declarations (both single and in blocks) - Added recognition of type aliases with proper distinction from regular types - Implemented special handling for init functions - Added support for anonymous functions, including nested function literals - Improved documentation and organization of query patterns These enhancements enable more accurate code navigation, better symbol extraction, and improved code intelligence for Go codebases.

Wheeler Date: Tue, 8 Apr 2025 19:40:19 -0700 Subject: [PATCH 5/5] feat: enhance Python tree-sitter parser with advanced language structures This commit significantly enhances the Python tree-sitter parser to support a comprehensive range of Python language constructs, enabling more accurate and detailed code analysis. Key improvements: - Added support for method definitions (instance, class, and static methods) - Added support for decorators on functions and classes - Added support for module-level variables and constants - Added support for async functions and methods - Added support for property getters/setters - Added support for type annotations in various contexts - Added support for dataclasses - Added support for nested functions and classes - Added support for generator functions - Added support for list/dict/set comprehensions - Added support for lambda functions - Added support for abstract base classes and methods The parser now handles Python's rich feature set more comprehensively, including special Python patterns like decorators, type annotations, and various comprehension types. This enables better code navigation, understanding, and analysis for Python codebases.
