# Helix Configuration Helix comes with support for `clangd` and `clang-format` out of the box! However, a small bit of configuration is needed for it to work correctly with SerenityOS. The following `.clangd` should be placed in the project root: ```yaml CompileFlags: CompilationDatabase: Build/x86_64 # Or whatever architecture you're targeting, e.g. aarch64 Add: [-D__serenity__] ``` You also need to configure the clangd server to detect headers properly from the Serenity toolchain. To do this, create a `.helix/languages.toml` file in the project root: ```toml [language-server.serenity] command = "clangd" args = ["--query-driver=/path/to/serenity/Toolchain/Local/**/*", "--header-insertion=never"] [[language]] name = "cpp" language-servers = ["serenity"] ``` > Make sure to replace `/path/to/serenity` with the actual path in the snippet above!
