Package for GNU Emacs that shows an overview during regex searching

Screenshots

There's also a ten minute video demo.

Ivy

Ivy is a generic completion mechanism for Emacs. While it operates similar to other completion schemes such as icomplete-mode, Ivy aims to be more efficient, smaller, simpler, and smoother to use yet highly customizable.

To try Ivy, just call M-x ivy-mode. This will enable generic Ivy completion for file and buffer names.

Installation

Install the Swiper package from MELPA / GNU ELPA.
