Ivy layer

Table of ContentsClose

1 Description

This layer enables Ivy for completion. It will replace the default completion by Helm.

These completion systems are the central control towers of Spacemacs, they are used to manage buffers, projects, search results, configuration layers, toggles and more…

Mastering your choice of completion system will make you a Spacemacs power user.

1.1 Features:

  • Project wide grep like text search via search-auto
  • Project wide text replacements using counsel-imenu
  • Buffer wide dynamic text search via swiper
  • Detailed configuration parameters for ivy appearance
  • Intuitive transient state
  • Advanced buffer information with ivy-rich

2 Install

To use this configuration layer, add it to your ~/.spacemacs. You will need to add ivy to the existing dotspacemacs-configuration-layers list in this file.

3 Configuration

3.1 General

You can customize ivy with the following variables:

  • ivy-wrap Whether C-n and C-p should wrap-around when at the first or last candidate. The default value is nil.
  • ivy-extra-directories Setting this to nil hides . and .. directories from file name completion. You can still go up a directory up by DEL. The default value is (“../”, “./”).
  • ivy-use-virtual-buffers Add bookmarks and recent files to buffer completion menu. The Spacemacs default is t.
  • ivy-height The height of the minibuffer. The Spacemacs default is 15.
  • ivy-use-selectable-prompt When non-nil, make the prompt line selectable like a candidate. The Spacemacs default value is t.
  • ivy-re-builders-alist An alist of regex building functions for each collection function. See ivy documentation for possible choices. Use spacemacs/ivy--regex-plus instead of ivy--regex-plus to get correct highlighting in the search results of spacemacs/search-project-auto and similar search commands provided by Spacemacs.

3.2 Advanced buffer information

To display more information about buffers set the layer variable ivy-enable-advanced-buffer-information to t which will enable ivy-rich.

Note that ivy-rich has been reported to be very slow on macOS. This feature is disabled by default.

(setq-default dotspacemacs-configuration-layers '(
  (ivy :variables ivy-enable-advanced-buffer-information t)))

4 Key bindings

If you choose ivy as completion system, make sure to read the official manual. In case you don’t want to read everything, at least familiarise with minibuffer key bindings.

Some useful key bindings are presented in the following table.

Key binding Description
RET call default action on current candidate
M-RET the same as RET but doesn’t close completion minibuffer
C-M-j use current input immediately (this can be used to create a new file in Find File)
tab complete partially
M-o show the list of valid actions on current candidate (then press any of described keys to execute it)
C-M-o the same as M-o but doesn’t close completion minibuffer
C-' use avy to quickly select completion on current page (sometimes faster than using arrows)
<ESC> close minibuffer

4.1 Transient state

Press M-SPC anytime in Ivy to get into the transient state.

Key binding Description
j select next candidate
k select previous candidate
d call default action on candidate
g the same as d but doesn’t close completion minibuffer
o leave transient state
