Awesome
flexible, simple tools for minibuffer completion in Emacs
This repository contains:
Ivy, a generic completion mechanism for Emacs.
Counsel, a collection of Ivy-enhanced versions of common Emacs commands.
Swiper, an Ivy-enhanced alternative to Isearch.
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 <kbd>M-x</kbd> ivy-mode
. This will enable
generic Ivy completion, including specific completion for file and
buffer names.
Installation
Install the ivy
package from GNU ELPA or MELPA.
Users of Debian ≥10 (and derivatives such as Ubuntu ≥18.04) can
install Ivy, Counsel, and Swiper with sudo apt install elpa-counsel
.
To add Hydra support sudo apt install elpa-ivy-hydra
.

Small config example
(ivy-mode)
(setq ivy-use-virtual-buffers t)
(setq enable-recursive-minibuffers t)
;; enable this if you want `swiper' to use it
;; (setq search-default-mode #'char-fold-to-regexp)
(global-set-key "\C-s" 'swiper)
(global-set-key (kbd "C-c C-r") 'ivy-resume)
(global-set-key (kbd "<f6>") 'ivy-resume)
(global-set-key (kbd "M-x") 'counsel-M-x)
(global-set-key (kbd "C-x C-f") 'counsel-find-file)
(global-set-key (kbd "<f1> f") 'counsel-describe-function)
(global-set-key (kbd "<f1> v") 'counsel-describe-variable)
(global-set-key (kbd "<f1> o") 'counsel-describe-symbol)
(global-set-key (kbd "<f1> l") 'counsel-find-library)
(global-set-key (kbd "<f2> i") 'counsel-info-lookup-symbol)
(global-set-key (kbd "<f2> u") 'counsel-unicode-char)
(global-set-key (kbd "C-c g") 'counsel-git)
(global-set-key (kbd "C-c j") 'counsel-git-grep)
(global-set-key (kbd "C-c k") 'counsel-ag)
(global-set-key (kbd "C-x l") 'counsel-locate)
(global-set-key (kbd "C-S-o") 'counsel-rhythmbox)
(define-key minibuffer-local-map (kbd "C-r") 'counsel-minibuffer-history)
Note: parts of this config can be replaced by using counsel-mode
.
Counsel
ivy-mode
ensures that any Emacs command using
completing-read-function
uses ivy for completion.
Counsel takes this further, providing versions of common Emacs
commands that are customised to make the best use of Ivy. For example,
counsel-find-file
has some additional keybindings. Pressing
<kbd>DEL</kbd> will move you to the parent directory.
Enabling counsel-mode
remaps built-in Emacs functions that have
counsel replacements:
Emacs command | Counsel equivalent |
---|---|
execute-extended-command | counsel-M-x |
describe-bindings | counsel-descbinds |
describe-function | counsel-describe-function |
describe-variable | counsel-describe-variable |
apropos-command | counsel-apropos |
describe-face | counsel-describe-face |
list-faces-display | counsel-faces |
find-file | counsel-find-file |
find-library | counsel-find-library |
imenu | counsel-imenu |
load-library | counsel-load-library |
load-theme | counsel-load-theme |
yank-pop | counsel-yank-pop |
info-lookup-symbol | counsel-info-lookup-symbol |
pop-to-mark-command | counsel-mark-ring |
bookmark-jump | counsel-bookmark |
Swiper
Swiper is an alternative to isearch that uses Ivy to show an overview of all matches.
A Helm version of Swiper is also available: swiper-helm.
Screenshots
There's also a ten minute video demo.
Frequently asked questions
Q: How do I enter an input that matches one of the candidates instead
of this candidate? Example: create a file bar
when a file
barricade
exists in the current directory.
A: Press <kbd>C-M-j</kbd>. Alternatively, you can make the prompt line selectable with (setq ivy-use-selectable-prompt t)
.
