Features

• Language Server Integrations - Implements the Language Server Protocol to connect Emacs to external servers for real-time code intelligence.
• Editor LSP JSON-RPC Clients - Provides the JSON-RPC communication layer necessary for asynchronous messaging between the editor and language servers.
• Semantic Code Analyzers - Facilitates semantic analysis of source code to resolve symbols, find references, and apply real-time linting.
• Code Action Providers - Offers context-sensitive code corrections and automated refactoring suggestions for specific lines of code.
• Code Completion - Suggests completions for symbols and identifiers as the user types by integrating with a completion frontend.
• Code Navigators - Enables jumping between definitions and references while visualizing symbol hierarchies across the project.
• Automated Code Refactoring - Executes automated structural changes to code based on server-provided refactoring suggestions.
• Debugger Protocol Integrations - Implements a client for the Debug Adapter Protocol to decouple the editor from specific debugger implementations.
• Debugging Protocols - Implements a standardized communication protocol to decouple the editor interface from specific debugger engines.
• Definition Navigation - Enables jumping directly from a symbol usage to its definition within the project.
• Language Server Protocol Clients - Integrates language servers into Emacs for completion, navigation, and diagnostics via LSP.
• Code Inspection Clients - Queries language servers to retrieve symbols, definitions, and diagnostics for real-time code inspection.
• Real-Time Code Diagnostics - Scans source code continuously to identify syntax errors and linting warnings in real time.
• Symbol Navigation - Provides comprehensive symbol navigation, including jumps to definitions and references across the project.
• DAP Protocol Clients - Functions as a DAP client to launch debug sessions, manage breakpoints, and step through code.
• Code Formatting - Organizes code layout based on configuration settings through automated formatting.
• On-Save Formatting - Automatically applies file formatting and fixes all auto-fixable issues upon saving the buffer.
• Automated Code Fixes - Executes automated corrections for identified errors and warnings through server-provided code actions.
• Inline Completions - Displays completion suggestions directly in the text stream while the user is idle.
• Inline Symbol Overlays - Shows diagnostics, hover messages, and available code actions directly on the current line.
• Code Formatting Tools - Automatically applies consistent styling and formatting rules to source code during the save process.
• Code Visualizers - Visualizes the relationship between types and symbols through graphical representations of code hierarchy.
• Debug Configuration Templates - Uses predefined launch schemas to map local host paths to remote or containerized environments for debugging.
• Editor-Integrated Debugging - Integrates debugging tools directly into the editor to manage breakpoints and inspect errors.
• Inlay Hint Renderers - Displays inline virtual text for parameter names and inferred types to provide immediate code context.
• Emacs Extensions - Provides a comprehensive set of editor enhancements for Emacs, including breadcrumbs and symbol trees.
• Automatic Signature Help Displays - Automatically displays function parameter hints and signatures as the user types a function call.
• IDE Extension Features - Provides professional development capabilities like semantic navigation and automated refactoring through IDE extension features.
• Breakpoint Debugging - Allows halting execution at breakpoints, inspecting variable state, and stepping through code via a debug adapter.
• Structural Code Navigation - Generates code outlines and structural navigation to help users understand the hierarchy of the current file.
• Hover Information Displays - Displays hover information, full documentation, and function signatures for the symbol at point.
• Symbol Searchers - Allows querying and locating specific identifiers across a single project or multiple workspaces.
• Symbol Tree Navigators - Provides a navigable symbol tree to allow quick movement between structures within a buffer.
• LSP Error Explanations - Shows detailed diagnostic information and corrective advice from the language server to resolve errors.
• Remote Debugging Protocols - Uses standardized protocols to communicate with remote debug agents for process execution control and memory inspection.
• DAP Debug Sessions - Launches debug sessions and manages breakpoints using the Debug Adapter Protocol.
• Peek Definitions - Allows users to peek at symbol definitions and references in a temporary window without leaving the current file.
• Documentation Hover Frames - Renders documentation and function signatures in independent child frames to avoid disrupting the main editor buffer.
• Server Session Isolation - Maintains separate server instances and state for each open project to ensure isolated language contexts.
• Symbol Renamers - Enables safe renaming of symbols and functions across the entire codebase.
• Semantic Color Mappings - Maps semantic tokens provided by the language server to specific editor colors for variables, functions, and types.
• Semantic Highlighters - Colors code elements based on semantic analysis of symbols and types provided by the language server.
