Ccls
ccls is a language server providing code completion, navigation, and semantic analysis for C and C++ projects. It focuses on the indexing and navigation of C-family codebases, enabling users to trace function calls and class hierarchies within a text editor.
The project is designed for large scale project indexing, employing parallel source scanning to process massive source trees. It maintains a global symbol index that supports incremental updates as files are saved to disk, ensuring cross-references and symbol lookups remain current.
The server covers a range of static code analysis workflows, including semantic highlighting and hover diagnostics. It provides capabilities for navigating code references, managing symbol hierarchies, and performing refactoring tasks such as renaming symbols across a workspace.
Features
- C-Family Development Workflows - Optimizes the development experience for C, C++, and Objective-C via advanced navigation and analysis tools.
- Codebase Indexing - Processes and indexes entire software projects to provide the necessary context for editor intelligence.
- Reference Navigators - Allows developers to jump instantly between linked references and their definitions across different files.
- Symbol Indexing - Maintains a comprehensive map of function definitions and call sites to facilitate rapid code navigation.
- LSP Server Implementations - Implements the server-side logic of the Language Server Protocol using JSON-RPC to provide IDE intelligence.
- Code Hierarchy Navigation - Provides interactive traversal of types, methods, and class inheritances to understand project structure.
- Language Server Implementations - Provides a full-featured language server for C and C++ including completion, navigation, and semantic analysis.
- Compiler-Integrated AST Parsing - Uses the Clang compiler frontend to parse source code into abstract syntax trees for deep semantic analysis.
- Symbol Index Updates - Refreshes only modified portions of the symbol index when files are saved to ensure real-time accuracy.
- Large Scale Indexing - Employs parallelism and efficient indexing techniques to process massive source trees.
- Call Graph Generators - Generates maps of function calls and execution paths to enable structural analysis of the codebase.
- Call Hierarchies - Enables exploration of static relationships between callers and callees of code symbols.
- Code Completion - Suggests keywords, symbols, and snippets during typing to accelerate development and reduce errors.
- Parallel Directory Scanning - Employs multi-threading to accelerate the initial scanning and indexing of large directory hierarchies.
- Semantic Diagnostics - Provides real-time hover information and diagnostics based on the semantic meaning of the code.
- Signature and Snippet Completion - Provides automatic suggestions for function signatures, argument lists, and return types during code entry.
- Static Code Analysis - Identifies potential errors and visualizes symbol relationships through static analysis and diagnostics.
- Symbol Renamers - Enables safe identifier renaming across the entire workspace to maintain codebase consistency.
- Semantic Highlighters - Applies visual styling to code based on the semantic analysis of symbols, types, and control flow.
- Herramientas de desarrollo - Language server for C/C++/ObjC
- Language Servers - Language server with cross-referencing and semantic highlighting.
