This is the online catalog of refactorings, to support my book Refactoring 2nd Edition.

This catalog of refactorings includes those refactorings described in my original book on Refactoring, together with the Ruby Edition.

Using the Catalog 

I've put together this catalog to help you find and explore the refactorings the 2nd edition. Each card shows the name used in the second edition together with any aliases for the refactoring (such as names for first edition refactorings that it replaces). The card links to the refactoring's online page. This page also contains the sketch for the refactoring.

The filter panel at the left allows you to select the refactorings by keyword, and also by which books they appear in. You can save the current filter settings to a URL by using the "#" permalink at the bottom of the filter panel.
