Consult provides search and navigation commands based on the Emacs completion function completing-read. Completion allows you to quickly select an item from a list of candidates. Consult offers asynchronous and interactive ‘consult-grep’ and ‘consult-ripgrep’ commands, and the line-based search command ‘consult-line’. Furthermore Consult provides an advanced buffer switching command ‘consult-buffer’ to switch between buffers, recently opened files, bookmarks and buffer-like candidates from other sources. Some of the Consult commands are enhanced versions of built-in Emacs commands. For example the command ‘consult-imenu’ presents a flat list of the Imenu with live preview, grouping and narrowing. Please take a look at the full list of commands.
Consult is fully compatible with completion systems centered around the standard Emacs ‘completing-read’ API, notably the default completion system, Vertico, Mct, and Icomplete.
This package keeps the completion system specifics to a minimum. The ability of the Consult commands to work well with arbitrary completion systems is one of the main advantages of the package. Consult fits well into existing setups and it helps you to create a full completion environment out of small and independent components.
You can combine the complementary packages Marginalia, Embark and Orderless with Consult. Marginalia enriches the completion display with annotations, e.g., documentation strings or file information. The versatile Embark package provides local actions, comparable to a context menu. These actions operate on the selected candidate in the minibuffer or at point in normal buffers. For example, when selecting from a list of files, Embark offers an action to delete the file. Additionally Embark offers a facility to collect completion candidates in a collect buffer. The section Embark integration documents in detail how Consult and Embark work together.

Most Consult commands follow the meaningful naming scheme ‘consult-<thing>’. Many commands implement a little known but convenient Emacs feature called "future history", which guesses what input the user wants. At a command prompt type ‘M-n’ and typically Consult will insert the symbol or thing at point into the input.
TIP: If you have Marginalia annotators activated, type ‘M-x ^consult’ to see all Consult commands with their abbreviated description. Alternatively, type ‘C-h a ^consult’ to get an overview of all Consult variables and functions with their descriptions.

the filter matches the complement. If a region is active, the region restricts
the filtering.

SPC, the filter matches the complement. In contrast to ‘consult-keep-lines’ this
function does not edit the buffer. If a region is active, the region restricts
the filtering.

may want to create your own commands which search through a predefined set of
info pages, for example:
(defun consult-info-emacs ()
"Search through Emacs info pages."
(interactive)
(consult-info "emacs" "efaq" "elisp" "cl" "compat"))
(defun consult-info-org ()

(interactive)
(consult-info "org"))
(defun consult-info-completion ()
"Search through completion info pages."

"corfu" "cape" "tempel"))

;; 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)))
Instead of ‘consult-completion-in-region’, you may prefer to see the completions directly in the buffer as a small popup. In that case, I recommend the Corfu package. There is a technical limitation of ‘consult-completion-in-region’ in combination with the Lsp modes. The Lsp server relies on the input at point, in order to generate refined candidate strings. Since the completion is transferred from the original buffer to the minibuffer, the server does not receive the updated input. In contrast, in-buffer Lsp completion for example via Corfu works properly since the completion takes place directly in the original buffer.

Consult enhances ‘completing-read’ with live previews of candidates, additional narrowing capabilities to candidate groups and asynchronously generated candidate lists. The internal ‘consult--read’ function, which is used by most Consult commands, is a thin wrapper around ‘completing-read’ and provides the special functionality. In order to support multiple candidate sources there exists the high-level function ‘consult--multi’. The architecture of Consult allows it to work with different completion systems in the backend, while still offering advanced features.
Next: Narrowing and grouping, Up: Special features [Contents][Index]
Some Consult commands support live previews. For example when you scroll through the items of ‘consult-line’, the buffer will scroll to the corresponding position. It is possible to jump back and forth between the minibuffer and the buffer to perform recursive editing while the search is ongoing.
Consult enables previews by default. You can disable them by adjusting the ‘consult-preview-key’ variable. Furthermore it is possible to specify keybindings which trigger the preview manually as shown in the example configuration. The default setting of ‘consult-preview-key’ is ‘any’ which means that Consult triggers the preview immediately on any key press when the selected candidate changes. You can configure each command individually with its own ‘:preview-key’. The following settings are possible:
A safe recommendation is to leave automatic immediate previews enabled in general and disable the automatic preview only for commands where the preview may be expensive due to file loading. Internally, Consult uses the value of ‘this-command’ to determine the ‘:preview-key’ customized. This means that if you wrap a ‘consult-*’ command within your own function or command, you will also need to add the name of your custom command to the ‘consult-customize’ call in order for it to be considered.
(consult-customize consult-ripgrep consult-git-grep consult-grep consult-bookmark consult-recent-file consult-xref consult--source-bookmark consult--source-file-register consult--source-recent-file consult--source-project-recent-file ;; my/command-wrapping-consult ;; disable auto previews inside my command :preview-key '(:debounce 0.4 any) ;; Option 1: Delay preview ;; :preview-key "M-.") ;; Option 2: Manual preview
In this case one may wonder what the difference is between using an Embark action on the current candidate in comparison to a manually triggered preview. The main difference is that the files opened by manual preview are closed again after the completion session. During preview some functionality is disabled to improve the performance, see for example the customization variables ‘consult-preview-variables’ and ‘consult-preview-allowed-hooks’. Only hooks listed in ‘consult-preview-allowed-hooks’ are executed. This variable applies to ‘find-file-hook’, ‘change-major-mode-hook’ and mode hooks, e.g., ‘prog-mode-hook’. In order to enable additional font locking during preview, add the corresponding hooks to the allow list. The following code demonstrates this for org-modern and hl-todo.
;; local modes added to prog-mode hooks (add-to-list 'consult-preview-allowed-hooks 'hl-todo-mode) (add-to-list 'consult-preview-allowed-hooks 'elide-head-mode) ;; enabled global modes (add-to-list 'consult-preview-allowed-hooks 'global-org-modern-mode) (add-to-list 'consult-preview-allowed-hooks 'global-hl-todo-mode)
Files larger than ‘consult-preview-partial-size’ are previewed partially. Delaying the preview is also useful for ‘consult-theme’, since the theme preview is slow. The delay results in a smoother UI experience.
;; Preview on any key press, but delay 0.5s
(consult-customize consult-theme :preview-key '(:debounce 0.5 any))
;; Preview immediately on M-., on up/down after 0.5s, on any other key after 1s
(consult-customize consult-theme
:preview-key
'("M-."
:debounce 0.5 "<up>" "<down>"
:debounce 1 any))
Next: Asynchronous search, Previous: Live previews, Up: Special features [Contents][Index]
Consult has special support for candidate groups. If the completion UI supports the grouping functionality, the UI separates the groups with thin lines and shows group titles. Grouping is useful if the list of candidates consists of candidates of multiple types or candidates from multiple sources, like the ‘consult-buffer’ command, which shows both buffers and recently opened files. Note that you can disable the group titles by setting the ‘:group’ property of the corresponding command to nil using the ‘consult-customize’ macro.
By entering a narrowing prefix or by pressing a narrowing key it is possible to restrict the completion candidates to a certain candidate group. When you use the ‘consult-buffer’ command, you can enter the prefix ‘b SPC’ to restrict list of candidates to buffers only. If you press ‘DEL’ afterwards, the full candidate list will be shown again. Furthermore a narrowing prefix key and a widening key can be configured which can be pressed to achieve the same effect, see the configuration variables ‘consult-narrow-key’ and ‘consult-widen-key’.
After pressing ‘consult-narrow-key’, the possible narrowing keys can be shown by pressing ‘C-h’. When pressing ‘C-h’ after some prefix key, the ‘prefix-help-command’ is invoked, which shows the keybinding help window by default. As a more compact alternative, there is the ‘consult-narrow-help’ command which can be bound to a key, for example ‘?’ or ‘C-h’ in the ‘consult-narrow-map’, as shown in the example configuration. If which-key is installed, the narrowing keys are automatically shown in the which-key window after pressing the ‘consult-narrow-key’.
Next: Multiple sources, Previous: Narrowing and grouping, Up: Special features [Contents][Index]
Consult has support for asynchronous generation of candidate lists. This feature is used for search commands like ‘consult-grep’, where the list of matches is generated dynamically while the user is typing a regular expression. The grep process is executed in the background. When modifying the regular expression, the background process is terminated and a new process is started with the modified regular expression.
The matches, which have been found, can then be narrowed using the installed Emacs completion-style. This can be powerful if you are using for example the ‘orderless’ completion style.
This two-level filtering is possible by splitting the input string. Part of the
input string is treated as input to grep and part of the input is used for
filtering. There are multiple splitting styles available, configured in
consult-async-split-styles-alist: ‘nil’, ‘comma’, ‘semicolon’ and ‘perl’. The default
splitting style is configured with the variable consult-async-split-style.
With the ‘comma’ and ‘semicolon’ splitting styles, the first word before the comma or semicolon is passed to grep, the remaining string is used for filtering. The ‘nil’ splitting style does not perform any splitting, the whole input is passed to grep.
The ‘perl’ splitting style splits the input string at a punctuation character, using a similar syntax as Perl regular expressions.
Examples:
Asynchronous processes like ‘find’ and ‘grep’ create an error log buffer ‘_*consult-async*’ (note the leading space), which is useful for troubleshooting. The prompt has a small indicator showing the process status:
Next: Embark integration, Previous: Asynchronous search, Up: Special features [Contents][Index]
Multiple synchronous candidate sources can be combined. This feature is used by the ‘consult-buffer’ command to present buffer-like candidates in a single menu for quick access. By default ‘consult-buffer’ includes buffers, bookmarks, recent files and project-specific buffers and files. It is possible to configure the list of sources via the ‘consult-buffer-sources’ variable. Arbitrary custom sources can be defined.
As an example, the bookmark source is defined as follows:
(defvar consult--source-bookmark
`(:name "Bookmark"
:narrow ?m
:category bookmark
:face consult-bookmark
:history bookmark-history
:items ,#'bookmark-all-names
:action ,#'consult--bookmark-action))
Required source fields:
Optional source fields:
The ‘:state’ and ‘:action’ fields of the sources deserve a longer explanation. The ‘:action’ function takes a single argument and is only called after selection with the selected candidate, if the selection has not been aborted. This functionality is provided for convenience and easy definition of sources. The ‘:state’ field is more general. The ‘:state’ function is a constructor function without arguments, which can perform some setup necessary for the preview. It must return a closure which takes an ACTION and a CANDIDATE argument. See the docstring of ‘consult--with-preview’ for more details about the ACTION argument.
By default, ‘consult-buffer’ previews buffers, bookmarks and files. Loading recent files or bookmarks can result in expensive operations. However it is possible to configure a manual preview as follows.
(consult-customize consult--source-bookmark consult--source-file-register consult--source-recent-file consult--source-project-recent-file :preview-key "M-.")
Sources can be added directly to the ‘consult-buffer-source’ list for convenience. For example, the following source lists all Org buffers and lets you create new ones.
(defvar org-source
(list :name "Org Buffer"
:category 'buffer
:narrow ?o
:face 'consult-buffer
:history 'buffer-name-history
:state #'consult--buffer-state
:new
(lambda (name)
(with-current-buffer (get-buffer-create name)
(insert "#+title: " name "\n\n")
(org-mode)
(consult--buffer-action (current-buffer))))
:items
(lambda ()
(consult--buffer-query :mode 'org-mode :as #'consult--buffer-pair))))
(add-to-list 'consult-buffer-sources 'org-source 'append)
One can create similar sources for other major modes. See the Consult wiki for many additional source examples. See also the documentation of ‘consult-buffer’ and of the internal ‘consult--multi’ API. The function ‘consult--multi’ can be used to create new multi-source commands.
Previous: Multiple sources, Up: Special features [Contents][Index]
NOTE: Install the ‘embark-consult’ package from MELPA, which provides Consult-specific Embark actions and the Occur buffer export.
Embark is a versatile package which offers context dependent actions, comparable to a context menu. See the Embark manual for an extensive description of its capabilities.
Actions are commands which can operate on the currently selected candidate (or target in Embark terminology). When completing files, for example the ‘delete-file’ command is offered. With Embark you can execute arbitrary commands on the currently selected candidate via ‘M-x’.
Furthermore Embark provides the ‘embark-collect’ command, which collects candidates and presents them in an Embark collect buffer, where further actions can be applied to them. A related feature is the ‘embark-export’ command, which exports candidate lists to a buffer of a special type. For example in the case of file completion, a Dired buffer is opened.
In the context of Consult, particularly exciting is the possibility to export the matching lines from ‘consult-line’, ‘consult-outline’, ‘consult-mark’ and ‘consult-global-mark’. The matching lines are exported to an Occur buffer where they can be edited via the ‘occur-edit-mode’ (press key ‘e’). Similarly, Embark supports exporting the matches found by ‘consult-grep’, ‘consult-ripgrep’ and ‘consult-git-grep’ to a Grep buffer, where the matches across files can be edited, if the wgrep package is installed. These three workflows are symmetric.

Consult can be installed from ELPA or MELPA via the Emacs built-in package manager. Alternatively it can be directly installed from the development repository via other non-standard package managers.
There is the Consult wiki, where additional configuration examples can be contributed.
IMPORTANT: It is recommended that you enable lexical binding in your configuration. Many Consult-related code snippets require lexical binding, since they use lambdas and closures.
Next: Custom variables, Up: Configuration [Contents][Index]
The Consult package only provides commands and does not add any keybindings or modes. Therefore the package is non-intrusive but requires a little setup effort. While the configuration example is long, it consists essentially of key bindings only, such that the risk of interference with other Emacs functionality is minimized.
In order to use the Consult commands, it is recommended to add keybindings for commands which are accessed often. Rarely used commands can be invoked via ‘M-x’. Feel free to only bind the commands you consider useful to your workflow. The configuration shown here relies on the ‘use-package’ macro, which is a convenient tool to manage package configurations.

Multiple Consult search commands like ‘consult-grep’ try to discover the current project and search in the project top level directory by default, if a project is found. Otherwise they fall back to the ‘default-directory’. By default, Consult uses the Emacs built-in project discovery support (‘project-current’ and ‘project-root’). It is possible to configure alternative methods via the customization variable ‘consult-project-function’.

NOTE: Consult supports fine-grained customization of individual commands. This configuration feature exists for experienced users with special requirements. There is the Consult wiki, where we collect further configuration examples.
Commands and buffer sources allow flexible, individual customization by using the ‘consult-customize’ macro. You can override any option passed to the internal ‘consult--read’ API. Note that since ‘consult--read’ is part of the internal API, options could be removed, replaced or renamed in future versions of the package.
Useful options are:
(consult-customize
;; Disable preview for `consult-theme' completely.
consult-theme :preview-key nil
;; Set preview for `consult-buffer' to key `M-.'
consult-buffer :preview-key "M-."
;; For `consult-line' change the prompt and specify multiple preview
;; keybindings. Note that you should bind <S-up> and <S-down> in the
;; `minibuffer-local-completion-map' or `vertico-map' to the commands which
;; select the previous or next candidate.
consult-line :prompt "Search: "
:preview-key '("S-<down>" "S-<up>"))
The configuration values are evaluated at runtime, just before the completion session is started. Therefore you can use for example ‘thing-at-point’ to adjust the initial input or the future history.
(consult-customize consult-line :add-history (seq-some #'thing-at-point '(region symbol))) (defalias 'consult-line-thing-at-point 'consult-line) (consult-customize consult-line-thing-at-point :initial (thing-at-point 'symbol))
Generally it is possible to modify commands for your individual needs by the following techniques:
Next: Bug reports, Previous: Configuration, Up: consult.el - Consulting completing-read [Contents][Index]
I use and recommend this combination of packages:
There exist multiple fine completion UIs beside Vertico, which are supported by Consult. Give them a try and find out which interaction model fits best for you.
Note that all packages are independent and can be exchanged with alternative components, since there exist no hard dependencies. Furthermore it is possible to get started with only default completion and Consult and add more components later to the mix. For example you can omit Marginalia if you don’t need annotations. I highly recommend the Embark package, but in order to familiarize yourself with the other components, you can first start without it - or you could use with Embark right away and add the other components later on.
We document a list of auxiliary packages in the Consult wiki. These packages integrate Consult with special programs or with other packages in the wider Emacs ecosystem.

If you find a bug or suspect that there is a problem with Consult, please carry out the following steps:
Minimal setup with Vertico for ‘emacs -Q’:

Please provide the necessary important information with your bug report:
When evaluating Consult-related code snippets you should enable lexical binding. Consult often relies on lambdas and lexical closures.

Next: Live preview, Up: Hacking [Contents][Index]
If you have a completion source that’s both dynamic and expensive to generate, ‘completing-read’ may not be the best choice. Instead, ‘consult--read’ serves as a thin wrapper around ‘completing-read’ that provides this functionality. For example, consider the following slow script that splits its input on space:
#!/usr/bin/env bash # simulate work sleep .1 # generate completion candidates printf "%s\n" "$*" | tr " " "\n" | sort
Let’s assume this script is callable as ‘testibus hello world’. To have Consult use it for completion, use ‘consult--async-command’:
(consult--read (consult--async-command (lambda (input) (list "testibus" (string-trim input)))) :prompt "run testibus: ")
If the completion candidates are generated by Lisp instead, use ‘consult--dynamic-collection’:
(consult--read
(consult--dynamic-collection
(lambda (input)
(sleep-for 0.1) ;; Simulate work
(sort (split-string (string-trim input) nil t) #'string<)))
:prompt "run testibus: ")
Previous: Creating asynchronous completion commands, Up: Hacking [Contents][Index]
Implementing live preview requires the definition of a state or preview function as defined by ‘consult--with-preview’. The preview function receives the candidate and some action to perform (e.g., ‘'preview’). In its simplest form supporting live preview, it looks something like this:
(defun testibus--preview (action cand)
(pcase action

(erase-buffer)
(insert (format "input: %s\n" cand))))))
See the docstring of ‘consult--with-preview’ for the lifecycle of the action argument. Once defined, we can use this preview function in ‘consult--read’:
(consult--read
(consult--dynamic-collection
(lambda (input)
(sleep-for 0.1) ;; Simulate work
(sort (split-string (string-trim input) nil t) #'string<)))
:prompt "run testibus: "
:state #'testibus--preview)
