About:
emacs-clang-complete-async provides asynchronous code completion for C, C++, Objective-C, and other languages supported by libclang. It leverages a separate backend process to prevent the Emacs editor from freezing during heavy code analysis. This results in a responsive user interface while delivering accurate, context-aware completions based on your project's syntax.
Key Features:
  • Asynchronous completion backend prevents editor lag
  • Uses libclang for accurate semantic analysis
  • Integrates with standard Emacs completion frameworks
  • Supports C, C++, Objective-C, and Objective-C++
Use Cases:
  • Large C/C++ projects where synchronous completion is too slow
  • Maintaining editor responsiveness during intensive code analysis
  • Developing in compiled languages within Emacs
Alternatives:
  • eglot – Modern LSP client that uses clangd for completion, generally more up-to-date and feature-rich.
  • company-mode – Generic completion framework that can use various backends, including clang or LSP.
