This post is part of a series which documents the vim-ruby-refactoring plugin.

Extract Local Variable

Extracts a visual selection into a local variable.

The refactoring: http://www.refactoring.com/catalog/introduceExplainingVariable.html

Example

Before refactoring:

Visually select the value you wish to extract
Hit your **** then type **relv **You will now see a prompt to enter the variable name: Variable name: mac_os

After refactoring:

The value platform.upcase.include?(‘MAC’) has been extracted into a local variable mac_os.

relv is the default binding for this refactoring, think Refactor Extract Local Variable.
