cquery is a highly-scalable, low-latency language server for C/C++/Objective-C built on libclang, designed for very large code bases like Chromium. It implements the Language Server Protocol to provide completion, cross-references, diagnostics, and semantic highlighting in editors like Emacs, Vim, and VSCode.
Use cases
- code completion for c++ in vim
- find all references in a large c++ codebase
- go to definition for c code
- semantic highlighting for c++ in emacs
- call hierarchy and inheritance hierarchy navigation
- diagnostics and clang fixits in vscode
- index a multi-million line c++ project
When to choose
- you are maintaining a legacy setup that already uses cquery
- you need an archived reference implementation of a C/C++ language server
When to avoid
- starting a new project - use clangd or ccls instead
- you need actively maintained tooling or bug fixes
- you cannot afford its large memory overhead on huge codebases
