RTags is a client/server application that indexes C/C++/ObjC code using clang, maintaining a persistent database of symbols, references, and definitions. It integrates with Emacs to provide follow-symbol, find-references, rename-symbol, and live diagnostics features.

Use cases

• jump to definition in c++ code from emacs
• find all references to a symbol in a large c++ codebase
• rename a symbol across a c project
• get live clang diagnostics and fixits in emacs
• index c/c++ code for fast symbol lookup

When to choose

• you use Emacs for C/C++ development and want fast, accurate code navigation
• you need persistent, incremental indexing of large C/C++ codebases
• you prefer clang-based tooling over LSP servers

When to avoid

• you use an editor other than Emacs (limited integration)
• you already rely on clangd or another LSP server
• you need ObjC support beyond limited coverage
