For a long time, probably around a decade, I have been using a refactoring tool built by Slovakian researcher Marián Vittek. It was probably one of the first refactoring tools to cross the “Refactoring Rubicon“.
It is an Emacs plugin that adds refactoring, navigation, completion and crossreference functionality for the C language. There is also some Java support, and they built a commercial C++ version.
Mostly it just works. Of course it has some trouble with heavy macro usage, it’s missing a few basic refactorings, e.g. it doesn’t extract an expression to a function returning a value correctly, so you need to edit the result. I haven’t really thought much about it until I started developing on a new computer and just took a quick look for a new version. I knew the project was kind of hibernating so I hadn’t been up-to-date with events.
To my sadness the xref-tech site was no more. After some googling I found that the C-version had survived as a SourceForge-project created already in 2009 by Marián.
This post is very much a payback for the good service Xrefactory have been giving me during many years. And a strong recommendation to you to look into c-xref if you are into Emacs and C-programming.
Do you know of any similar tools for C?
