💖 NAME 💖

okay bestie, gather round — this is rtags-rdm, the manual page for the RTags server. it's giving "the backend that does all the actual work while you vibe in your editor" ✨

🦋 SYNOPSIS 🦋

rtags-rdm [OPTION]...

🌸 DESCRIPTION 🌸

okay so. RTags is a client/server application that indexes C/C++ code and keeps a persistent file-based database of references, declarations, definitions, symbolnames etc. and yes, there's also limited support for ObjC/ObjC++. it lets you find symbols by name (nested class and namespace scope included, we're not cowards). most importantly?? we give you proper follow-symbol and find-references support. we also have neat little things like rename-symbol, and integration with clang's "fixits" (http://clang.llvm.org/diagnostics.html). we also integrate with flymake using clang's vastly superior errors and warnings. and since RTags constantly reindexes "dirty" files, you get live updates of compiler errors and warnings. and because we already know how to compile your sources, we have a way to quickly bring up the preprocessed output of the current source file in a buffer. slay.

now, while existing taggers like gnu global, cscope, etags, ctags etc do a decent job for C, they often fall a little bit short for C++. with its incredible lexical complexity, parsing C++ is an incredibly hard task, and we make no bones about the fact that the only reason we are able to improve on the current tools is because of clang (http://clang.llvm.org/). RTags is named RTags in recognition of Roberto Raggi, on whose C++ parser we intended to base this project — but he assured us clang was the way to go. the name stuck though. 💅
