gcc-etags README

gcc-etags is a GCC plugin to create etags compatible files for C++. Tags are a (rather primitive) way of navigating source code in Emacs or other editors. ETag is the implementation that comes with Emacs and the tags basically consist of a short regex, the name of the tag and where to find it. While ETag has a very primitive mechanism of parsing files gcc-etags uses the GCC plugin interface to utilize GCC’s C++ frontend.

This is more of an experimental package I wrote to understand the GCC plugin interface. It is very hacky and currently does not even support struct/class members. Much of the code is inspired by Boris Kolpackov’s blog series about GCC plugins: Parsing C++ with GCC plugins, Part 1, Part 2, and Part 3. Also checkout the GCC wiki on Plugins and the GCC documentation.


gcc-etags requires a new version of GCC (4.5+). On Ubuntu/Debian the gcc-*-plugin-dev package is required (e.g., gcc-4.6-plugin-dev for GCC 4.6). To build it simply call make.


To use gcc-etags simply call g++ with the following parameters: -S -fplugin\./ To make things easier there is a wrapper script available. Theoretically gcc-etags can utilize a projects Makefile and change the gcc/g++ calls to the appropriated gcc-etags calls. There is a script available to achieve this.

Something went wrong with that request. Please try again.
