Add comprehensive signature and docstring support to Serena's symbol retrieval system using LSP signatureHelp and hover methods. ## Core Features ### LSP Protocol Integration - Add SignatureHelp, SignatureInformation, and ParameterInformation types - Implement request_signature_help() methods in both async and sync LanguageServer - Support full LSP 3.17 signatureHelp specification with proper error handling ### Symbol Enhancement - Add signature and docstring properties to Symbol class with getters/setters - Extend to_dict() method with optional include_signature/include_docstring parameters - Maintain full backward compatibility with existing Symbol API ### Intelligent Content Retrieval - Implement get_signature_and_docstring() method in SymbolManager - Prioritize signatureHelp for signatures, fallback to hover for documentation - Parse multiple LSP content formats: markdown, string lists, structured objects - Extract clean documentation from code blocks and technical formatting ### Tool Integration - Enhance FindSymbolTool with optional signature/docstring parameters - Update GetSymbolsOverviewTool for consistent API across symbol tools - Automatic symbol enrichment when signature/docstring inclusion requested ## Test Coverage ### Enhanced Test Resources (+328 lines) - TypeScript: Comprehensive JSDoc comments, interfaces, typed functions - Java: Extensive Javadoc with parameter descriptions and examples - Rust: Idiomatic doc comments with examples and proper formatting ### Comprehensive Test Suite - New test_signature_docstring.py with 10 unit tests covering: - Property behavior and dictionary serialization - LSP response parsing (signatureHelp, hover variants) - Fallback logic and error handling - Symbol enrichment workflows ### Integration Testing - End-to-end tests across Python, TypeScript, Java, Rust - Validation of optional behavior and backward compatibility - Real language server integration testing ## Architecture The implementation follows Serena's layered architecture: LSP Layer → SymbolManager → Symbol → Tools → Agent ### Key Design Decisions - Optional feature activation: only retrieves data when explicitly requested - Graceful degradation: handles language servers with limited signatureHelp support - Robust parsing: supports various LSP hover content formats - Performance conscious: minimal overhead when feature not used ### Language Server Compatibility - Intelligent fallback between signatureHelp and hover methods - Handles missing position data with sensible defaults - Works with existing language servers (Pyright, TypeScript, JDTLS, rust-analyzer) ## Usage Examples ```python # Get symbols with signature and docstring find_tool.apply_ex(name_path="function", include_signature=True, include_docstring=True) # Symbol overview with documentation overview_tool.apply_ex(relative_path="file.py", include_signature=True, include_docstring=True) # Direct API usage signature, docstring = symbol_manager.get_signature_and_docstring(symbol) ``` ## Quality Assurance - All existing tests pass (no regressions) - 100% backward compatibility maintained - Full type safety with mypy compliance - Comprehensive error handling and logging 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
Implement comprehensive signature extraction that captures full function/method signatures with parameters, types, and default values from LSP hover responses. ## Major Improvements ### Full Multi-line Signature Support - Extract complete function signatures with all parameters and type annotations - Preserve multi-line formatting for complex signatures - Support for methods, functions, and class constructors - Clean removal of LSP prefixes: "(method)", "(function)", "(class)" ### Enhanced Demo Script - Updated demo to showcase SerenaAgent.__init__ with 11 parameters - Improved signature display with proper indentation - Visual formatting for multi-line signatures - Better docstring truncation and display ### Example Output ``` ✍️ Signature: def __init__( self: Self@SerenaAgent, project: str | None = None, project_activation_callback: (() -> None) | None = None, serena_config: SerenaConfigBase | None = None, context: SerenaAgentContext | None = None, modes: list[SerenaAgentMode] | None = None, enable_web_dashboard: bool | None = None, enable_gui_log_window: bool | None = None, log_level: Literal['DEBUG', 'INFO', 'WARNING', 'ERROR', 'CRITICAL'] | None = None, trace_lsp_communication: bool | None = None, tool_timeout: float | None = None ) -> None ``` ### Technical Implementation - State-machine based parsing for multi-line code blocks - Intelligent signature boundary detection (ending with `) -> Type` or `):`) - Proper handling of Python type hints and union types - Preservation of parameter formatting and indentation This resolves the requirement for full signature extraction including input parameter names and types, providing comprehensive semantic information for code understanding and documentation workflows. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
…ing tests - Removed all unittest.mock dependencies from test_signature_docstring.py - Replaced mock language server with real Python language server using parametrize fixture - Updated tests to work with actual Python code from test repository (test_repo/services.py) - Tests now validate signature/docstring functionality against real language server responses - Added robustness for cases where LSP may return None for some operations - Fixed ruff errors: removed unused variable and combined endswith() calls into tuple - Fixed type annotation for signature_lines variable - All 10 tests pass with real language server integration 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
