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

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 <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.

Documentation

Manual

The manual is available as HTML.

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

The source file for the Info page is here.

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 <kbd>DEL</kbd> will move you to the parent directory.

Enabling counsel-mode remaps built-in Emacs functions that have counsel replacements:

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.

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).
