C-xrefactory - A refactoring tool for C/Java and Emacs

TL;DR

c-xrefactory is a free emacs refactoring tool and code browser for C (and Java).

Easiest way to install is using el-get (see note):

M-x el-get-install<ENTER>c-xrefactory<ENTER>

Place cursor on an identifier and go to definition (F-6), navigate between occurrances (F-3, F-4), refactor (F-11) with rename, mark some code and extract function and so on. Your C programming and code will never be the same.

When installed correctly there will be an Emacs menu called C-xref for easy access to most functions.

Help!

This code is pre-historic legacy. It seems to have been born in a world of copy-paste-hack-and-debug, there are no unit tests, or any tests at all for that matter.

I'm on a long-time quest to resurrect this code to understandable, maintainable and developable standard. This is hard, difficult and time consuming, as it is almost impossible to understand what anything does. At this point I've added a couple of smoke/functional tests, that at least should crash if something basic becomes broken.

If you think you can help, I'll be happy to take it, even if it is only adding one line of understanding in src/NOTES.md...

The Story

Once apon a time there was http://www.xref.sk, a site promoting possibly the worlds first refactoring browser to cross the "Refactoring's Rubicon".

At that time it had a free Java and C version, and a paid C++ version. Development seems to have been headed by a Marián Vittek.

Marián have been hard to track down and http://www.xref.sk seems to be going up and (mostly) down and there has been no support for many years.

NOTE: It seems that http://www.xrefactory.com/ is a better and more stable URL to the original Xrefactory, where it is still available.

Marián made a C-version, c-xref, available under GPL already 2009 on SourceForge. The reason seems to have been to allow parallell installations of free and non-free versions. c-xref seems to be intended to be limited to C and Emacs. Actually it's not. It is all but identical to the original full/free C/Java refactoring browser from http://www.xref.sk. So Java is also fully (?) supported.

About This Clone

As I'm almost dependent on this and refactoring tools for C is sadly lacking, I decided to pick this up and work a bit on it, maybe even make it a bit more visible, by moving it to GitHub.

No-one would be more happy than me if the C++ version where also put in the public domain.

If someone has contact with Marián, please inform him and ask him to contact me. Perhaps we can create something great from this together with others who might be interested.

NOTE: You can easily install el-get in your running emacs using a snippet from el-gets github repo, but don't forget to add the el-get pieces in you emacs init.
