ccls is a C/C++/Objective-C language server implementing the Language Server Protocol, originating from cquery. It provides code completion, cross references, call/inheritance/member hierarchies, semantic highlighting, and whole-project indexing for editor integration.
Use cases
- set up C++ code completion and go-to-definition in my editor
- find all references and callers of a C++ function
- view class inheritance hierarchies in C++ code
- get semantic syntax highlighting for C/C++ in vim or emacs
- rename symbols across a large C++ codebase
- index a large C/C++ project for fast code navigation
When to choose
- you need deep cross-reference and hierarchy features for C/C++/Objective-C
- you want a language server with a global index of the whole codebase
- you use an editor like Vim, Emacs, or Neovim without a full IDE
When to avoid
- you prefer clangd, which is more actively maintained and standard
- you work mainly in languages other than C/C++/Objective-C
- memory-constrained environments indexing very large projects
