clangd

clangd is a language server, and provides C++ IDE features to editors. This is not its documentation.

• the website is https://clangd.llvm.org/.
• the bug tracker is https://github.com/clangd/clangd/issues
• the source code is hosted at https://github.com/llvm/llvm-project/tree/main/clang-tools-extra/clangd.
• the website source code is at https://github.com/llvm/clangd-www/

Communication channels

If you have any questions or feedback, you can reach community and developers through one of these channels:

• chat: #clangd room hosted on LLVM's Discord channel.
• user questions and feature requests can be asked in the clangd topic on LLVM Discussion Forums

Building and testing clangd

For a minimal setup on building clangd:

• Clone the LLVM repo to $LLVM_ROOT.

• Create a build directory, for example at $LLVM_ROOT/build.

• Inside the build directory run: cmake $LLVM_ROOT/llvm/ -DCMAKE_BUILD_TYPE=Release -DLLVM_ENABLE_PROJECTS="clang;clang-tools-extra".

  • We suggest building in Release mode as building DEBUG binaries requires considerably more resources. You can check Building LLVM with CMake documentation for more details about cmake flags.
  • In addition to that using Ninja as a generator rather than default make is preferred. To do that consider passing -G Ninja to cmake invocation.
  • Finally, you can turn on assertions via -DLLVM_ENABLE_ASSERTS=On.

• Afterwards you can build clangd with cmake --build $LLVM_ROOT/build --target clangd, similarly run tests by changing target to check-clangd.
