Introduction: Automated Refactoring Techniques for AppCode.<ref>http://en.wikipedia.org/wiki/Ruby_on_Rails</ref>

AppCode is an Integrated Development Environment (IDE) for Objective-C,C, C++, and JavaScript development built on JetBrains’ IntelliJ IDEA platform, which is built on Java. Users can extend its abilities by either installing plug-ins created for IntelliJ Platform, or they can write their own plug-ins.

Code refactoring is the process of restructuring existing computer code – changing the factoring – without changing its external behavior. Many a times, we face the need to change the name of a variable in our code- mostly because we find another one better suited for its functionality. Doing this manually can be time consuming & often leads to many mistakes. That is why, many new IDEs (Integrated Development Environments) come with inbuilt functions for refactoring. As you read further, you will know that refactoring is not limited to changing variable name. There are many things IDEs allow programmers to do to edit their code. These changes are not logical, in the sense that they do not make any change to functionality or behavior of the program; but are needed to improve code in terms of understanding & user friendliness.
