Faster C++ code intelligence with whole codebase indexing
Whole codebase indexing speeds up C++ code intelligence
GitHub Copilot CLI now supports whole codebase indexing for C++ repositories, creating a persistent index of symbols across projects to speed up code-intelligence requests for definitions, references, and symbol searches.
The feature is enabled by default and uses the Microsoft C++ Language Server to resolve types and relationships between files, though initial indexing may increase memory usage on large repositories.
From the source
Whole codebase indexing (WCI) creates a persistent index of symbols across your C++ project, including files that aren't currently open. The Microsoft C++ Language Server uses your project's compilation information to resolve types, symbols, includes, and relationships between files. WCI makes that symbol information available for reuse instead of rediscovering it for each request.
