Swiper

Package for GNU Emacs that gives you an overview as you search for a regex

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 method for Emacs, similar to icomplete-mode. It aims to be more efficient, more simple, and more pleasant to use than the alternatives. It's also highly customizable and very small.

To try it, just call M-x ivy-mode, and all generic completion, including file and buffer names, will be done with Ivy.

Installation

You can install the package from MELPA / GNU ELPA. Here is some typical configuration:

(ivy-mode 1)
(setq ivy-use-virtual-buffers t)
(global-set-key "\C-s" 'swiper)
(global-set-key "\C-r" 'swiper)
(global-set-key (kbd "C-c C-r") 'ivy-resume)
(global-set-key [f6] 'ivy-resume)

Issues

Recently, the ivy package that provided ivy.el was removed from MELPA. Now, the swiper package provides ivy.el. You should remove the outdated ivy package from your system.
