Migrated from FalkorDB/code-graph-backend PR #95. Original issue: FalkorDB/code-graph-backend#93 Resolves #531 Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
- Replace wildcard import with explicit Entity and File imports - Fix tree-sitter queries: Kotlin grammar uses 'identifier' not 'type_identifier' - Fix get_entity_name: use 'identifier' for all entity types - Separate superclass/interface in add_symbols: first delegation specifier is base_class, rest are implement_interface - Use self._captures() instead of direct query.captures() calls - Handle constructor_invocation in delegation specifiers (e.g. Shape(...)) - Fix source_analyzer second_pass: use entity.resolved_symbols instead of iterating raw symbol nodes, so graph edges use resolved entity IDs - Fix resolve_method: use 'identifier' instead of 'simple_identifier' - Add unit tests and Kotlin fixture (11 tests, all passing) Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
- Fix resolve_symbol return type annotation: Entity -> list[Entity] in abstract and Kotlin implementations to match actual behavior - Fix pyproject.toml indentation for tree-sitter-kotlin dependency - Add path.resolve() in analyze_sources for LSP compatibility - Remove unused exception variable Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
…ion heuristic - Restore C# analyzer registration in SourceAnalyzer (removed unintentionally) - Fix resolve_symbol return type annotation in Java/Python analyzers (-> list[Entity]) - Improve Kotlin delegation specifier handling: use constructor_invocation as class signal instead of blindly treating first specifier as base_class Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

Adds Kotlin (
.kt,.kts) analysis to the code graph pipeline alongside existing Python, Java, and C# support.New:
