C/C++ code completion with emacs using Irony and GTAGS
Blog Post: http://cachestocaches.com/2015/8/c-completion-emacs/
This repository includes two sets of files. The first, cpp_completion.el contains the emacs lisp configuration file required to install/activate the packages within emacs. Include this file in your ~/.emacs.d/ folder, and then put (load-file "~/.emacs.d/cpp_completion.el") in your init.el. The other files are extremely simple example source files for checking that the code completion is working correctly. They include a main.cpp file, and a couple of other files, rect.cpp and rect.hpp, which define a simple class definition for testing.
The details of how to properly use the code provided in this repository, and to fully activate Irony and GTAGS, can be found in this blog post.
