To install this package, run in Emacs:
M-x package-install RET vertico RET
Vertico provides a performant and minimalistic vertical completion UI based on
the default completion system. The main focus of Vertico is to provide a UI
which behaves correctly under all circumstances. By reusing the built-in
facilities system, Vertico achieves full compatibility with built-in Emacs
completion commands and completion tables. Vertico only provides the completion
UI but aims to be highly flexible, extensible and modular. Additional
enhancements are available as extensions or complementary packages. The code
base is small and maintainable. The main
vertico.el package is only about 600
lines of code without white space and comments.
TABand selected with
M-RETor by moving the point to the prompt.
Vertico defines its own local keymap in the minibuffer which is derived from
minibuffer-local-map. The keymap keeps most of the
intact and remaps and binds only a handful of commands. Note in particular the
vertico-insert and the bindings of
Vertico is available from GNU ELPA. You can install it directly via
package-install. After installation, you can activate the global minor mode with
M-x vertico-mode. In order to configure Vertico and other packages in your
init.el, you may want to take advantage of
use-package. Here is an example
;; Enable vertico (use-package vertico :init (vertico-mode) ;; Different scroll margin ;; (setq vertico-scroll-margin 0) ;; Show more candidates ;; (setq vertico-count 20) ;; Grow and shrink the Vertico minibuffer ;; (setq vertico-resize t) ;; Optionally enable cycling for `vertico-next' and `vertico-previous'. ;; (setq vertico-cycle t) ) ;; Persist history over Emacs restarts. Vertico sorts by history position. (use-package savehist :init (savehist-mode)) ;; A few more useful configurations... (use-package emacs :init ;; Add prompt indicator to `completing-read-multiple'. ;; We display [CRM<separator>], e.g., [CRM,] if the separator is a comma. (defun crm-indicator (args) (cons (format "[CRM%s] %s" (replace-regexp-in-string "\\`\\[.*?]\\*\\|\\[.*?]\\*\\'" "" crm-separator) (car args)) (cdr args))) (advice-add #'completing-read-multiple :filter-args #'crm-indicator) ;; Do not allow the cursor in the minibuffer prompt (setq minibuffer-prompt-properties '(read-only t cursor-intangible t face minibuffer-prompt)) (add-hook 'minibuffer-setup-hook #'cursor-intangible-mode) ;; Emacs 28: Hide commands in M-x which do not work in the current mode. ;; Vertico commands are hidden in normal buffers. ;; (setq read-extended-command-predicate ;; #'command-completion-default-include-p) ;; Enable recursive minibuffers (setq enable-recursive-minibuffers t))
I recommend to give Orderless completion a try, which is different from the prefix TAB completion used by the basic default completion system or in shells.
;; Optionally use the `orderless' completion style. (use-package orderless :init ;; Configure a custom style dispatcher (see the Consult wiki) ;; (setq orderless-style-dispatchers '(+orderless-dispatch) ;; orderless-component-separator #'orderless-escapable-split-on-space) (setq completion-styles '(orderless basic) completion-category-defaults nil completion-category-overrides '((file (styles partial-completion)))))
basic completion style is specified as fallback in addition to
order to ensure that completion commands which rely on dynamic completion
+orderless-dispatch in the Consult wiki for an advanced Orderless
style dispatcher. Additionally enable
partial-completion for file path
partial-completion is important for file wildcard support. Multiple
files can be opened at once with
find-file if you enter a wildcard. You may also
initials completion style a try.
See also the Vertico Wiki for additional configuration tips. For more general documentation read the chapter about completion in the Emacs manual. If you want to create your own completion commands, you can find documentation about completion in the Elisp manual.
The bindings of the
minibuffer-local-completion-map are not available in Vertico
by default. This means that TAB works differently from what you may expect from
the default Emacs completion system.
If you prefer to have the default completion commands a key press away you can
add new bindings or even replace the Vertico bindings. Then the default
completion commands behave as usual. For example you can use
M-TAB to cycle
between candidates if you have set
(define-key vertico-map "?" #'minibuffer-completion-help) (define-key vertico-map (kbd "M-RET") #'minibuffer-force-complete-and-exit) (define-key vertico-map (kbd "M-TAB") #'minibuffer-complete)
orderless completion style does not support completion of a common prefix
substring, as you may be familiar with from shells or the basic default
completion system. The reason is that the Orderless input string is usually not
a prefix. In order to support completing prefixes you may want to combine
substring in your
(setq completion-styles '(substring orderless basic))
Alternatively you can experiment with the built-in completion-styles, e.g.,
partial-completion style is important to
add if you want to open multiple files at once with
find-file using wildcards.
In order to open multiple files at once, you have to move to the prompt and then
(setq completion-styles '(basic substring partial-completion flex))
Because Vertico is fully compatible with Emacs default completion system,
further customization of completion behavior can be achieved by setting the
designated Emacs variables. For example, one may wish to disable
case-sensitivity for file and buffer matching when built-in completion styles
are used instead of
(setq read-file-name-completion-ignore-case t read-buffer-completion-ignore-case t completion-ignore-case t)
completion-at-point command is usually bound to
TAB. In case you
want to use Vertico for completion-at-point/completion-in-region, you can use
consult-completion-in-region provided by the Consult package.
;; Use `consult-completion-in-region' if Vertico is enabled. ;; Otherwise use the default `completion--in-region' function. (setq completion-in-region-function (lambda (&rest args) (apply (if vertico-mode #'consult-completion-in-region #'completion--in-region) args)))
completion-in-region-function setting also affects TAB completion in the
eval-expression) is used.
You may also want to look into my Corfu package, which provides a minimal
completion system for
completion-in-region in a child frame popup. Corfu is also
a narrowly focused package and developed in the same spirit as Vertico.
We maintain small extension packages to Vertico in this repository in the
subdirectory extensions/. The extensions are installed together with Vertico if
you pull the package from ELPA. The extensions are inactive by default and can
be enabled manually if desired. Furthermore it is possible to install all of the
files separately, both
vertico.el and the
vertico-*.el extensions. Currently the
following extensions come with the Vertico ELPA package:
vertico-buffer-modeto display Vertico in a separate buffer.
vertico-flat-modeto enable a flat, horizontal display.
vertico-grid-modeto enable a grid display.
vertico-indexed-modeto select indexed candidates with prefix arguments.
vertico-mouse-modeto support for scrolling and candidate selection.
vertico-repeatrepeats the last completion session.
vertico-reverse-modeto reverse the display.
vertico-unobtrusive-modedisplays only the topmost candidate.
See the Commentary of those files for configuration details. With these
extensions it is possible to adapt Vertico such that it matches your preference
or behaves similar to other familiar UIs. For example, the combination
vertico-directory resembles Ido in look and feel. For an
interface similar to Helm, the extension
vertico-buffer allows you to configure
freely where the completion buffer opens, instead of growing the minibuffer.
vertico-buffer will adjust the number of displayed candidates
according to the buffer height.
Configuration example for
;; Configure directory extension. (use-package vertico-directory :after vertico :ensure nil ;; More convenient directory navigation commands :bind (:map vertico-map ("RET" . vertico-directory-enter) ("DEL" . vertico-directory-delete-char) ("M-DEL" . vertico-directory-delete-word)) ;; Tidy shadowed file names :hook (rfn-eshadow-update-overlay . vertico-directory-tidy))
Vertico offers the
vertico-multiform-mode which allows you to configure Vertico
per command or per completion category. The
vertico-buffer-mode enables a
Helm-like buffer display, which takes more space but also displays more
candidates. This verbose display mode is useful for commands like
consult-outline since the buffer display allows you to get a better overview
over the entire current buffer. But for other commands you want to keep using
the default Vertico display.
vertico-multiform-mode solves this configuration
;; Enable vertico-multiform (vertico-multiform-mode) ;; Configure the display per command. ;; Use a buffer with indices for imenu ;; and a flat (Ido-like) menu for M-x. (setq vertico-multiform-commands '((consult-imenu buffer indexed) (execute-extended-command unobtrusive))) ;; Configure the display per completion category. ;; Use the grid display for files and a buffer ;; for the consult-grep commands. (setq vertico-multiform-categories '((file grid) (consult-grep buffer)))
Temporary toggling between the different display modes is possible. Bind the following commands:
(define-key vertico-map "\M-V" #'vertico-multiform-vertical) (define-key vertico-map "\M-G" #'vertico-multiform-grid) (define-key vertico-map "\M-F" #'vertico-multiform-flat) (define-key vertico-map "\M-R" #'vertico-multiform-reverse) (define-key vertico-map "\M-U" #'vertico-multiform-unobtrusive)
You can use your own functions or even lambdas to configure the completion behavior per command or per completion category. The function must have the calling convention of a mode, i.e., it takes a single argument, which is either 1 to turn on the mode and -1 to turn off the mode.
;; Configure `consult-outline' as a scaled down TOC in a separate buffer (setq vertico-multiform-commands `((consult-outline buffer ,(lambda (_) (text-scale-set -1)))))
Furthermore you can tune buffer-local settings per command or category.
;; Change the default sorting function. ;; See `vertico-sort-function' and `vertico-sort-override-function'. (setq vertico-multiform-commands '((describe-symbol (vertico-sort-function . vertico-sort-alpha)))) (setq vertico-multiform-categories '((symbol (vertico-sort-function . vertico-sort-alpha)) (file (vertico-sort-function . sort-directories-first)))) ;; Sort directories before files (defun sort-directories-first (files) (setq files (vertico-sort-history-length-alpha files)) (nconc (seq-filter (lambda (x) (string-suffix-p "/" x)) files) (seq-remove (lambda (x) (string-suffix-p "/" x)) files)))
Combining these features allows us to fine-tune the completion display even more
by adjusting the
vertico-buffer-display-action. We can for example reuse the
current window for commands of the
consult-grep category (
consult-ripgrep). Note that this configuration is
incompatible with Consult preview, since the previewed buffer is usually shown
in exactly this window. Nevertheless this snippet demonstrates the flexibility
of the configuration system.
;; Configure the buffer display and the buffer display action (setq vertico-multiform-categories '((consult-grep buffer (vertico-buffer-display-action . (display-buffer-same-window))))) ;; Disable preview for consult-grep commands (consult-customize consult-ripgrep consult-git-grep consult-grep :preview-key nil)
As another example, the following code uses
(ido-mode 'buffer), i.e., Ido when it is enabled only for completion of
vertico-cycle set to
t is necessary here to prevent completion
candidates from disappearing when they scroll off-screen to the left.
(setq vertico-multiform-categories '((buffer flat (vertico-cycle . t))))
Vertico integrates well with complementary packages, which enrich the completion UI. These packages are fully supported:
In order to get accustomed with the package ecosystem, I recommed the following quick start approach:
embark-act. I am using the mnemonic keybindings
C-.since these commands allow you to act on the object at point or in the minibuffer.
consult-bufferwith preview or the line-based search
occur-modebuffers and from
The ecosystem is modular. You don't have to use all of these components. Use
only the ones you like and the ones which fit well into your setup. The steps 1.
to 4. introduce no new commands over plain Emacs. Step 5. introduces the new
embark-dwim. In step 6. you get the Consult commands,
some offer new functionality not present in Emacs already (e.g.,
and some are substitutes (e.g.,
An often requested feature is the ability to display the completions in a child
frame popup. Personally I am critical of using child frames for minibuffer
completion. From my experience it introduces more problems than it solves. Most
importantly child frames hide the content of the underlying buffer. Furthermore
child frames do not play well together with changing windows and entering
recursive minibuffer sessions. On top, child frames can feel slow and sometimes
flicker. A better alternative is the
vertico-buffer display which can even be
configured individually per command using
vertico-multiform. On the plus side of
child frames, the completion display appears at the center of the screen, where
your eyes are focused. Please give the following packages a try and judge for
There are many alternative completion UIs, each UI with its own advantages and disadvantages.
Vertico aims to be 100% compliant with all Emacs commands and achieves that with
a minimal code base, relying purely on
completing-read while avoiding to invent
its own APIs. Inventing a custom API as Helm or Ivy is explicitly avoided in
order to increase flexibility and package reuse. Due to its small code base and
reuse of the Emacs built-in facilities, bugs and compatibility issues are less
likely to occur in comparison to completion UIs or full completion systems,
which reimplement a lot of functionality.
Since Vertico only provides the UI, you may want to combine it with some of the complementary packages, to give a full-featured completion experience similar to Helm or Ivy. Overall the packages in the spirit of Vertico have a different style than Helm or Ivy. The idea is to have smaller independent components, which one can add and understand step by step. Each component focuses on its niche and tries to be as non-intrusive as possible. Vertico targets users interested in crafting their Emacs precisely to their liking - completion plays an integral part in how the users interacts with Emacs.
There are other interactive completion UIs, which follow a similar philosophy:
*Completions*buffer and enhances it with automatic updates and additional keybindings, to select a candidate and move between minibuffer and completions buffer. Mct can be configured to open only when requested. Furthermore since Mct uses a fully functional buffer you can reuse all your familar buffer commands inside the completions buffer. The main distinction to Vertico's approach is that
*Completions*buffer displays all matching candidates. This has the advantage that you can interact freely with the candidates and jump around with Isearch or Avy. On the other hand it necessarily causes a slowdown in comparison to Vertico, which only displays a subset of candidates. Mct supports completion in region via its

Vertico is robust in most scenarios. However some completion commands make certain assumptions about the completion styles and the completion UI. Some of these assumptions may not hold in Vertico or other UIs and require minor workarounds.
org-olpath-completing-read to complete the outline path in
org-refile-use-outline-path is non-nil.
Unfortunately the implementation of this Org completion table assumes that the
basic completion style is used. The table is incompatible with completion styles
orderless. In order to fix the issue at the root, the
completion table should make use of completion boundaries similar to the
built-in file completion table. In your user configuration you can prioritize
;; Alternative 1: Use the basic completion style (setq org-refile-use-outline-path 'file org-outline-path-complete-in-steps t) (advice-add #'org-olpath-completing-read :around (lambda (&rest args) (minibuffer-with-setup-hook (lambda () (setq-local completion-styles '(basic))) (apply args))))
Alternatively you may want to disable the outline path completion in steps. The completion on the full path can be quicker since the input string matches directly against substrings of the full path, which is useful with Orderless. However the list of possible completions becomes much more cluttered.
;; Alternative 2: Complete full paths (setq org-refile-use-outline-path 'file org-outline-path-complete-in-steps nil)
org-agenda-filter completion function
org-agenda-filter-completion-function) does not make use of completion
TAB completion (
minibuffer-complete) does not work for
this reason. This affects Vertico and also the Emacs default completion system.
For example if you enter
+tag<0 TAB the input is replaced with
0:10 which is not
correct. With preserved completion boundaries, the expected result would be
The text menu bar works well with Vertico but always shows a
buffer, which is unwanted if you use the Vertico UI. This completion buffer can
be disabled with an advice. If you disabled the standard GUI menu bar and prefer
the Vertico interface you may also overwrite the default F10 keybinding.
(global-set-key [f10] #'tmm-menubar) (advice-add #'tmm-add-prompt :after #'minibuffer-hide-completions)
ffap-menu shows the
*Completions* buffer by default like
tmm-menubar, which is unnecessary with Vertico. This completion buffer can be
disabled as follows.
(advice-add #'ffap-menu-ask :around (lambda (&rest args) (cl-letf (((symbol-function #'minibuffer-completion-help) #'ignore)) (apply args))))
Dynamic completion tables (
etc.) should work well with Vertico. However the requirement is that the
completion style is enabled. The
basic style performs prefix filtering by
passing the input to the completion table (or the dynamic completion table
basic completion style must not necessarily be configured with
highest priority, it can also come after other completion styles like
(setq completion-styles '(basic)) ;; (setq completion-styles '(orderless basic)) (completing-read "Dynamic: " (completion-table-dynamic (lambda (str) (list (concat str "1") (concat str "2") (concat str "3")))))
bbdb-create read multiple arguments from
the minibuffer with
completing-read, one at a time, until you submit an empty
string. You should type
vertico-exit-input) to finish the loop. Directly
vertico-exit) does not work since the first candidate is
The underlying issue is that
completing-read always allows you to exit with the
empty string, which is called the null completion, even if the
argument is non-nil. Try the following two calls to
(completing-read "Select: " '("first" "second" "third") nil 'require-match) (completing-read "Select: " '("first" "second" "third") nil 'require-match nil nil "")
In both cases the empty string can be submitted. In the first case no explicit
default value is specified and Vertico preselects the first candidate. In order
to exit with the empty string, press
M-RET. In the second case the explicit
default value "" is specified and Vertico preselects the prompt, such that
exiting with the empty string is possible by pressing
In combination with Orderless, hostnames are not made available for completion
/ssh:. In order to avoid this problem, the
basic completion style
should be specified for the file completion category, such that
basic is tried
(setq completion-styles '(orderless basic) completion-category-overrides '((file (styles basic partial-completion))))

completion-style machinery: You may also
