Swiper
Package for GNU Emacs that shows an overview during regex searching.
The package uses the ivy back end for the overview, see also
swiper-helm.
Screenshots
There's also a ten minute video demo.
Ivy
Ivy is a generic completion mechanism for Emacs. While it operates
similarly 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, including specific completion for file and
buffer names.
Installation
Install the swiper package from MELPA / GNU ELPA.
