Ivy

GNU-devel ELPA GNU ELPA MELPA MELPA Stable

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 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.

Documentation

Manual

The manual is available as HTML.

Installing ivy from GNU ELPA or MELPA also installs the manual under the (ivy) Info node.

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

GNU-devel ELPA GNU ELPA MELPA MELPA Stable

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 DEL 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

GNU-devel ELPA GNU ELPA MELPA MELPA Stable

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.

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 C-M-j. Alternatively, you can make the prompt line selectable with (setq ivy-use-selectable-prompt t).
