This covers which programming languages GrepAI can index and trace for call graph analysis. You get full indexing plus tracing for the usual suspects like Go, TypeScript, Python, Rust, Java, and C++, while languages like Ruby, Swift, and Kotlin only get indexed for semantic search without call graph support. The distinction matters because tracing requires language-specific parsing to build caller/callee relationships, while indexing works on any text file. Includes config examples for enabling specific languages, excluding test files, and choosing between fast regex mode or precise tree-sitter parsing. Honestly most useful as a reference when you're setting up a new project and need to know if your stack will get full tracing or just search.
