Automated excerpt
C++ code intelligence in GitHub Copilot CLI is now faster with support for whole codebase indexing. Whole codebase indexing (WCI) creates a persistent index of symbols across your C++ project, including files that aren’t currently open. Whole codebase indexing is enabled by default because its persistent symbol index helps the Microsoft C++ Language Server efficiently understand relationships across your entire project.
