C / C++

Language server: clangd

Setup

clangd ships with LLVM:

# macOS
brew install llvm

# Ubuntu/Debian
apt install clangd

# or download from https://github.com/clangd/clangd/releases

Requirements

• compile_commands.json in the project root or build directory
• clangd in PATH

Generate compile_commands.json

clangd needs compile commands to resolve includes:

# CMake
cmake -DCMAKE_EXPORT_COMPILE_COMMANDS=ON -B build
ln -s build/compile_commands.json .

# Bear (for Makefiles)
bear -- make

# Meson
# Generated automatically in the build directory

Without compile_commands.json, clangd can’t resolve #include directives and symbol resolution will be degraded.

Supported Operations

• find symbol — functions, classes, structs, enums
• hover — types and declarations
• check — clangd diagnostics
• edit replace — function/class bodies
• rename — cross-file rename
• list symbols — file outline

CMakeLists.txt Detection

Krait detects CMakeLists.txt as the project root marker for C/C++ projects.
