clangd-query/dist/compilation-db.d.ts

Fast C++ code intelligence CLI tool for humans and AI agents. Provides semantic search, source code reading and usage lookups.

/**
 * Ensures a compile_commands.json exists in the .cache/clangd-query directory.
 *
 * This function follows the startup logic from the technical specification:
 * 1. First checks if compile_commands.json already exists in .cache/clangd-query/build
 * 2. If not, checks if CMakeLists.txt exists in the project root
 * 3. If CMakeLists.txt exists, runs CMake to generate compile_commands.json
 * 4. All generated files are kept within .cache/clangd-query to avoid interfering with
 *    the user's build setup or other tools like VSCode's clangd
 *
 * The compile_commands.json file is essential for clangd to understand how to
 * compile each source file in the project, enabling accurate code analysis,
 * navigation, and symbol indexing.
 *
 * @param projectRoot - The absolute path to the C++ project root directory
 * @returns The path to the directory containing compile_commands.json
 * @throws Error if no CMakeLists.txt is found or if CMake fails to generate
 *         the compilation database
