Factorus: automated refactoring in Vim

Factorus is a Vim plugin for automated refactoring. It provides renaming of methods and classes, encapsulation of variables, and even method extraction, with a few very intutitive commands.

Features

The following table shows which features Factorus supports for which languages:

	Add Parameter	Encapsulate Variable	Extract Method (Automated)	Extract Method (Manual)	Rename Argument	Rename Class	Rename Method	Rename Field
Java	✓	✓	✓	✓	✓	✓	✓	✓
Python	✓	N/A	✓	✓	✓	✓	✓	N/A
C/C++	✓	N/A	✓	✓	✓	N/A	✓	✓

Additionally, for C/C++, Factorus supports the following refactorings:

	Rename Type	Rename Macro	Rename Namespace
C/C++	✓	✓	N/A

NOTE: Factorus support for C++ currently uses the same code as for C; as such, Factorus may not work properly for more complex C++ code.

Factorus also has commands for reverting changes and rebuilding projects, for stability and sanity testing.
