From 749f793c08abb3488e7c02861cea1b83e8ba0d59 Mon Sep 17 00:00:00 2001 From: Eric Wheeler Date: Tue, 8 Apr 2025 19:27:00 -0700 Subject: [PATCH] feat: enhance C++ tree-sitter parser with advanced language structures This enhancement significantly expands the C++ parser's capabilities to recognize and extract a wide range of modern C++ language constructs, improving code navigation and analysis. 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.
