Marks Dart bare call extraction as verified against Flutter codebase. Completes the language-specific getReceiverType implementation tracking by documenting that Dart methods are properly nested in class bodies and selector-based method calls are now handled.
Addresses TypeScript abstract classes missing by adding abstract_class_declaration to classTypes. Fixes single-expression arrow functions being silently dropped by preventing extractName from searching identifiers in arrow_function/function_expression bodies, ensuring they return for proper parent name resolution instead of incorrectly using body identifiers.
Addresses Ruby methods inside modules missing owner in qualified_name by adding visitNode hook to extract module AST nodes. Methods inside modules now get Module::method qualified names with proper containment relationships. Includes ExtractorContext wiring with pushScope/popScope for language hooks and updates isInsideClassLikeNode to include module kind for nested method handling.
Addresses C#'s property_declaration nodes (public string Name { get; set; }) by adding propertyTypes support and extractProperty method. Improves field extraction to handle C#'s nested variable_declaration > variable_declarator structure. Adds base_list handling in extractInheritance for C#'s `: Parent, IInterface` syntax where base class and interfaces are combined in a single colon-separated list.
Addresses C++ classes missing from .h files where extension-based detection defaults to 'c' language which has no class extraction support. Adds looksLikeCpp() heuristic that scans first 8KB for C++-specific patterns (namespace, class, template, access specifiers) to promote .h files to 'cpp' language when C++ constructs are detected. Ensures cpp grammar is loaded alongside c to handle potential .h promotion during parsing.
Addresses C++ macros like NLOHMANN_JSON_NAMESPACE_BEGIN that cause tree-sitter to misparse namespace blocks as function_definitions. Adds isMisparsedFunction hook to filter macro artifacts while still visiting their bodies to extract legitimate class/struct/enum definitions hidden inside the misparsed "function" scope.
Addresses Rust's impl block syntax where trait implementations (`impl Trait for Type`) and trait supertraits (`trait Sub: Super`) create inheritance relationships. Adds getReceiverType to extract method receiver types from impl blocks, enabling proper method-to-struct relationships and qualified name resolution. Verified against Deno codebase and moved from "Needs Verification" to completed language support.
Addresses tree-sitter AST structure verification where Python methods are nested within class bodies like Java and Swift, eliminating the need for getReceiverType extraction. Verified against Flask codebase and moved from "Needs Verification" to completed language support.
Updates example code to use the simplified two-parameter form of getImpactRadius instead of the options object pattern, making the documentation consistent with current API usage.
Replaces the focused search quality improvement loop with a complete language verification system. The new guide provides a systematic battery of tests (explore, search, call chains, impact analysis, edge extraction, node completeness, and real-world LLM prompts) to verify CodeGraph fully supports a programming language before marking it as production-ready.
Swift methods in extension blocks are already parsed correctly by tree-sitter, which treats `extension Type { }` as `class_declaration` and automatically includes the owner type in qualified names. No getReceiverType implementation needed.
Documents the systematic process for testing and improving search result relevance when LLMs query CodeGraph. Provides step-by-step loop for diagnosing issues with method search ranking, implementing getReceiverType hooks for languages where methods appear outside their owner type in the AST, and validating fixes with real codebases.
