- Introduction
RTags is a client/server application that indexes C/C++ code and keeps a
persistent file-based database of references, declarations, definitions,
symbolnames etc. There's also limited support for ObjC/ObjC++. It allows you
to find symbols by name (including nested class and namespace scope). Most
importantly we give you proper follow-symbol and find-references support. We
also have neat little things like rename-symbol, integration with clang's
"fixits" (https://clang.llvm.org/diagnostics.html). We also integrate with
flymake using clang's vastly superior errors and warnings. Since RTags
constantly will reindex "dirty" files you get live updates of compiler errors
and warnings. Since 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.
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 (https://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.

- TLDR Quickstart
Build RTags
+BEGIN_SRC sh
git clone --recursive https://github.com/Andersbakken/rtags.git
cd rtags
cmake -DCMAKE_EXPORT_COMPILE_COMMANDS=1 .
make
+END_SRC
Start the RTags daemon (=rdm=)
+BEGIN_SRC sh
./bin/rdm &
+END_SRC
Index the RTags project, and wait until =rdm= is silent
+BEGIN_SRC sh
./bin/rc -J .
+END_SRC
Open source file in =emacs=
+BEGIN_SRC sh
emacs +74:34 src/rdm.cpp
+END_SRC
Load =rtags.el=
+BEGIN_EXAMPLE
M-: (load-file "rtags.el") RET
+END_EXAMPLE
Ensure =rc= can be found
+BEGIN_EXAMPLE
M-x set-variable RET rtags-path RET "../bin" RET
+END_EXAMPLE
Call =rtags-find-symbol-at-point=
+BEGIN_EXAMPLE
M-x rtags-find-symbol-at-point RET
+END_EXAMPLE
Your location is now on the definition of =Server::instance()=

RTags is still under development and is not the most stable piece of software
you'll ever find. We're constantly working to improve on it.
