     15 Consult provides search and navigation commands based on the Emacs completion
     16 function [[https://www.gnu.org/software/emacs/manual/html_node/elisp/Minibuffer-Completion.html][completing-read]]. Completion allows you to quickly select an item from a
     17 list of candidates. Consult offers asynchronous and interactive =consult-grep= and
     18 =consult-ripgrep= commands, and the line-based search command =consult-line=.
     19 Furthermore Consult provides an advanced buffer switching command =consult-buffer=
     20 to switch between buffers, recently opened files, bookmarks and buffer-like
     21 candidates from other sources. Some of the Consult commands are enhanced
     22 versions of built-in Emacs commands. For example the command =consult-imenu=
     23 presents a flat list of the Imenu with [[#live-previews][live preview]], [[#narrowing-and-grouping][grouping and narrowing]].
     24 Please take a look at the [[#available-commands][full list of commands]].
     25 
     26 Consult is fully compatible with completion systems centered around the standard
     27 Emacs =completing-read= API, notably the default completion system, [[https://github.com/minad/vertico][Vertico]], [[https://github.com/protesilaos/mct][Mct]],
     28 and [[https://www.gnu.org/software/emacs/manual/html_node/emacs/Icomplete.html][Icomplete]].
     29 
     30 This package keeps the completion system specifics to a minimum. The ability of
     31 the Consult commands to work well with arbitrary completion systems is one of
     32 the main advantages of the package. Consult fits well into existing setups and
     33 it helps you to create a full completion environment out of small and
     34 independent components.
     35 
     36 You can combine the complementary packages [[https://github.com/minad/marginalia/][Marginalia]], [[https://github.com/oantolin/embark/][Embark]] and [[https://github.com/oantolin/orderless][Orderless]] with
     37 Consult. Marginalia enriches the completion display with annotations, e.g.,
     38 documentation strings or file information. The versatile Embark package provides
     39 local actions, comparable to a context menu. These actions operate on the
     40 selected candidate in the minibuffer or at point in normal buffers. For example,
     41 when selecting from a list of files, Embark offers an action to delete the file.
     42 Additionally Embark offers a facility to collect completion candidates in a
     43 collect buffer. The section [[#embark-integration][Embark integration]] documents in greater detail how
     44 Consult and Embark work together.

     69 Most Consult commands follow the meaningful naming scheme =consult-<thing>=.
     70 Many commands implement a little known but convenient Emacs feature called
     71 "future history", which guesses what input the user wants. At a command prompt
     72 type =M-n= and typically Consult will insert the symbol or thing at point into
     73 the input.
     74 
     75 *TIP:* If you have [[https://github.com/minad/marginalia][Marginalia]] annotators activated, type =M-x ^consult= to see
     76 all Consult commands with their abbreviated description. Alternatively, type
     77 =C-h a ^consult= to get an overview of all Consult variables and functions with
     78 their descriptions.

     89 #+findex: consult-project-buffer
     90 #+findex: consult-recent-file
     91 #+findex: consult-bookmark
     92 - =consult-buffer= (=-other-window=, =-other-frame=): Enhanced version
     93   of =switch-to-buffer= with support for virtual buffers. Supports live preview
     94   of buffers and narrowing to the virtual buffer types. You can type =f SPC= in
     95   order to narrow to recent files. Press =SPC= to show ephemeral buffers.
     96   Supported narrowing keys:
     97   - b Buffers
     98   - SPC Hidden buffers
     99   - * Modified buffers
    100   - f Files (Requires =recentf-mode=)
    101   - r File registers
    102   - m Bookmarks
    103   - p Project
    104   - Custom [[#multiple-sources][other sources]] configured in =consult-buffer-sources=.
    105 - =consult-project-buffer=: Variant of =consult-buffer= restricted to buffers and
    106   recent files of the current project. You can add custom sources to
    107   =consult-project-buffer-sources=. The command may prompt you for a project if
    108   you invoke it from outside a project.
    109 - =consult-bookmark=: Select or create bookmark. To select bookmarks you might use the
    110   =consult-buffer= as an alternative, which can include a bookmark virtual buffer
    111   source. Note that =consult-bookmark= supports preview of bookmarks and
    112   narrowing.
    113 - =consult-recent-file=: Select from recent files with preview.
    114   You might prefer the powerful =consult-buffer= instead, which can include
    115   recent files as a virtual buffer source. The =recentf-mode= enables tracking of
    116   recent files.

    125 #+findex: consult-yank-from-kill-ring
    126 #+findex: consult-yank-replace
    127 #+findex: consult-kmacro
    128 - =consult-yank-from-kill-ring=: Enhanced version of =yank= to select an item
    129   from the =kill-ring=. The selected text previewed as overlay in the buffer.
    130 - =consult-yank-pop=: Enhanced version of =yank-pop= with DWIM-behavior, which
    131   either replaces the last =yank= by cycling through the =kill-ring=, or if there
    132   has not been a last =yank= consults the =kill-ring=. The selected text previewed
    133   as overlay in the buffer.
    134 - =consult-yank-replace=: Like =consult-yank-pop=, but always replaces the last
    135   =yank= with an item from the =kill-ring=.
    136 - =consult-kmacro=: Select macro from the macro ring and execute it.
    137 
    138 ** Register
    139 :properties:
    140 :description: Searching through registers and fast access
    141 :end:
    142 #+cindex: register
    143 
    144 #+findex: consult-register
    145 #+findex: consult-register-load
    146 #+findex: consult-register-store
    147 #+findex: consult-register-format
    148 #+findex: consult-register-window
    149 - =consult-register=: Select from list of registers. The command
    150   supports narrowing to register types and preview of marker positions. This
    151   command is useful to search the register contents. For quick access use the
    152   commands =consult-register-load=, =consult-register-store= or the built-in Emacs
    153   register commands.
    154 - =consult-register-format=: Set =register-preview-function= to this function for
    155   an enhanced register formatting. See the [[#use-package-example][example configuration]].
    156 - =consult-register-window=: Replace =register-preview= with this function for a
    157   better register window. See the [[#use-package-example][example configuration]].
    158 - =consult-register-load=: Utility command to quickly load a register.
    159   The command either jumps to the register value or inserts it.
    160 - =consult-register-store=: Improved UI to store registers depending on the current
    161   context with an action menu. With an active region, store/append/prepend the
    162   contents, optionally deleting the region when a prefix argument is given.
    163   With a numeric prefix argument, store/add the number. Otherwise store point,
    164   frameset, window or kmacro. Usage examples:
    165   * =M-' x=: If no region is active, store point in register =x=.
    166     If a region is active, store the region in register =x=.
    167   * =M-' M-w x=: Store window configuration in register =x=.
    168   * =C-u 100 M-' x=: Store number in register =x=.

    170 ** Navigation
    171 :properties:

    174 #+cindex: navigation
    175 
    176 #+findex: consult-goto-line
    177 #+findex: consult-mark
    178 #+findex: consult-global-mark
    179 #+findex: consult-outline
    180 #+findex: consult-imenu
    181 #+findex: consult-imenu-multi
    182 - =consult-goto-line=: Jump to line number enhanced with live preview.
    183   This is a drop-in replacement for =goto-line=.
    184 - =consult-mark=: Jump to a marker in the =mark-ring=. Supports live
    185   preview and recursive editing.
    186 - =consult-global-mark=: Jump to a marker in the =global-mark-ring=.
    187   Supports live preview and recursive editing.
    188 - =consult-outline=: Jump to a heading of the outline. Supports narrowing
    189   to a heading level, live preview and recursive editing.
    190 - =consult-imenu=: Jump to imenu item in the current buffer. Supports
    191   live preview, recursive editing and narrowing.
    192 - =consult-imenu-multi=: Jump to imenu item in project buffers, with
    193   the same major mode as the current buffer. Supports live preview,
    194   recursive editing and narrowing. This feature has been inspired by
    195   [[https://github.com/vspinu/imenu-anywhere][imenu-anywhere]].
    196 
    197 ** Search
    198 :properties:
    199 :description: Line search, grep and file search
    200 :end:
    201 #+cindex: search
    202 
    203 #+findex: consult-line
    204 #+findex: consult-line-multi
    205 #+findex: consult-keep-lines
    206 #+findex: consult-focus-lines
    207 - =consult-line=: Enter search string and select from matching lines.
    208   Supports live preview and recursive editing. The symbol at point and the
    209   recent Isearch string are added to the "future history" and can be accessed
    210   by pressing =M-n=. When =consult-line= is bound to the =isearch-mode-map= and
    211   is invoked during a running Isearch, it will use the current Isearch string.
    212 - =consult-line-multi=: Search dynamically across multiple buffers. By default
    213   search across project buffers. If invoked with a prefix argument search across
    214   all buffers. The candidates are computed on demand based on the input. The
    215   command behaves like =consult-grep=, but operates on buffers instead of files.
    216 - =consult-keep-lines=: Replacement for =keep/flush-lines= which uses the current
    217   completion style for filtering the buffer. The function updates the buffer
    218   while typing. In particular =consult-keep-lines= can narrow down an exported
    219   Embark collect buffer further, relying on the same completion filtering as
    220   ~completing-read~. If the input begins with the negation operator, i.e., ~! SPC~,
    221   the filter matches the complement. If a region is active, the region restricts
    222   the filtering.
    223 - =consult-focus-lines=: Temporarily hide lines by filtering them using the
    224   current completion style. Call with =C-u= prefix argument in order to show the
    225   hidden lines again. If the input begins with the negation operator, i.e., ~!
    226   SPC~, the filter matches the complement. In contrast to =consult-keep-lines= this
    227   function does not edit the buffer. If a region is active, the region restricts
    228   the filtering.
    229 
    230 ** Grep and Find
    231 :properties:
    232 :description: Searching through the filesystem
    233 :end:
    234 #+cindex: grep
    235 #+cindex: find
    236 #+cindex: locate
    237 
    238 #+findex: consult-grep
    239 #+findex: consult-ripgrep
    240 #+findex: consult-git-grep
    241 #+findex: consult-find
    242 #+findex: consult-locate
    243 - =consult-grep=, =consult-ripgrep=, =consult-git-grep=: Search for regular expression
    244   in files. Consult invokes Grep asynchronously, while you enter the search
    245   term. After at least =consult-async-min-input= characters, the search gets
    246   started. Consult splits the input string into two parts, if the first
    247   character is a punctuation character, like =#=. For example
    248   =#regexps#filter-string=, is split at the second =#=. The string =regexps= is passed
    249   to Grep. Note that Consult transforms Emacs regular expressions to expressions
    250   understand by the search program. Always use Emacs regular expressions at the
    251   prompt. If you enter multiple regular expressions separated by space only
    252   lines matching all regular expressions are shown. In order to match space
    253   literally, escape the space with a backslash. The =filter-string= is passed to
    254   the /fast/ Emacs filtering to further narrow down the list of matches. This is
    255   particularly useful if you are using an advanced completion style like
    256   orderless. =consult-grep= supports preview. If the =consult-project-function=
    257   returns non-nil, =consult-grep= searches the current project directory.
    258   Otherwise the =default-directory= is searched. If =consult-grep= is invoked
    259   with prefix argument =C-u M-s g=, you can specify one or more comma-separated files
    260   and directories manually.
    261 - =consult-find=, =consult-locate=: Find file by matching the path against a regexp.
    262   Like for =consult-grep=, either the project root or the current directory is the
    263   root directory for the search. The input string is treated similarly to
    264   =consult-grep=, where the first part is passed to find, and the second part is
    265   used for Emacs filtering.  Prefix arguments to =consult-find= work just like those
    266   for the consult grep commands.
    267 
    268 ** Compilation
    269 :properties:

    271 :end:
    272 #+cindex: compilation errors
    273 
    274 #+findex: consult-compile-error
    275 #+findex: consult-flymake
    276 #+findex: consult-xref
    277 - =consult-compile-error=: Jump to a compilation error. Supports live preview
    278   narrowing and recursive editing.
    279 - =consult-flymake=: Jump to Flymake diagnostic. Supports live preview and
    280   recursive editing. The command supports narrowing. Press =e SPC=, =w SPC=, =n SPC=
    281   to only show errors, warnings and notes respectively.
    282 - =consult-xref=: Integration with xref. This function can be set as
    283   =xref-show-xrefs-function= and =xref-show-definitions-function=.
    284 
    285 ** Histories
    286 :properties:
    287 :description: Navigating histories
    288 :end:
    289 #+cindex: history
    290 
    291 #+findex: consult-complex-command
    292 #+findex: consult-history
    293 #+findex: consult-isearch-history
    294 - =consult-complex-command=: Select a command from the
    295   =command-history=. This command is a =completing-read= version of
    296   =repeat-complex-command= and is also a replacement for the =command-history=
    297   command from chistory.el.
    298 - =consult-history=: Insert a string from the current buffer history, for example
    299   the Eshell or Comint history. You can also invoke this command from the
    300   minibuffer. In that case =consult-history= uses the history stored in the
    301   =minibuffer-history-variable=. If you prefer =completion-at-point=, take a look at
    302   =cape-history= from the [[https://github.com/minad/cape][Cape]] package.
    303 - =consult-isearch-history=: During an Isearch session, this command picks a
    304   search string from history and continues the search with the newly selected
    305   string. Outside of Isearch, the command allows you to pick a string from the
    306   history and starts a new Isearch. =consult-isearch-history= acts as a drop-in
    307   replacement for =isearch-edit-string=.
    308

    316 #+findex: consult-minor-mode-menu
    317 #+findex: consult-mode-command
    318 - =consult-minor-mode-menu=: Enable/disable minor mode. Supports
    319   narrowing to on/off/local/global modes by pressing =i/o/l/g SPC=
    320   respectively.
    321 - =consult-mode-command=: Run a command from the currently active minor or major
    322   modes. Supports narrowing to local-minor/global-minor/major mode via the keys
    323   =l/g/m=.
    324 
    325 ** Org Mode

    332 - =consult-org-heading=: Similar to =consult-outline=, for Org
    333   buffers. Supports narrowing by heading level, priority and TODO
    334   state, as well as live preview and recursive editing.
    335 - =consult-org-agenda=: Jump to an agenda heading. Supports
    336   narrowing by heading level, priority and TODO state, as well as
    337   live preview and recursive editing.

    345 - =consult-man=: Find Unix man page, via Unix =apropos= or =man -k=. =consult-man= opens
    346   the selected man page using the Emacs =man= command.
    347 - =consult-info=: Full text search through info pages. If the command is invoked
    348   from within an ~*info*~ buffer, it will search through the current manual. You
    349   may want to create your own commands which search through a predefined set of
    350   info pages, for example:
    351 #+begin_src emacs-lisp
    352   (defun consult-info-emacs ()
    353     "Search through Emacs info pages."
    354     (interactive)

    379   Supports live preview of the theme while scrolling through the candidates.
    380 - =consult-preview-at-point= and =consult-preview-at-point-mode=: Command and minor
    381   mode which previews the candidate at point in the =*Completions*= buffer. This
    382   mode is relevant if you use [[https://git.sr.ht/~protesilaos/mct][Mct]] or the default =*Completions*= UI.
    383 - =consult-completion-in-region=: In case you don't use [[https://github.com/minad/corfu][Corfu]] as your in-buffer
    384   completion UI, this function can be set as =completion-in-region-function=. Then
    385   your minibuffer completion UI (e.g., Vertico or Icomplete) will be used for
    386   =completion-at-point=.
    387   #+begin_src emacs-lisp
    388     ;; Use `consult-completion-in-region' if Vertico is enabled.
    389     ;; Otherwise use the default `completion--in-region' function.
    390     (setq completion-in-region-function
    391           (lambda (&rest args)
    392             (apply (if vertico-mode
    393                        #'consult-completion-in-region
    394                      #'completion--in-region)
    395                    args)))
    396   #+end_src
    397   Instead of =consult-completion-in-region=, you may prefer to see the
    398   completions directly in the buffer as a small popup. In that case, I recommend
    399   either the [[https://github.com/minad/corfu][Corfu]] or the [[https://github.com/company-mode/company-mode][Company]] package. There is a technical limitation of
    400   =consult-completion-in-region= in combination with Lsp-mode or Eglot. The Lsp
    401   server relies on the input at point, in order to generate refined candidate
    402   strings. Since the completion is transferred from the original buffer to the
    403   minibuffer, the server does not receive the updated input. LSP completion
    404   works with Corfu or Company though, which perform the completion directly in
    405   the original buffer.

    407 * Special features
    408 :properties:
    409 :description: Enhancements over built-in `completing-read'
    410 :end:
    411 
    412 Consult enhances =completing-read= with live previews of candidates, additional
    413 narrowing capabilities to candidate groups and asynchronously generated
    414 candidate lists. The internal =consult--read= function, which is used by most
    415 Consult commands, is a thin wrapper around =completing-read= and provides the
    416 special functionality. In order to support multiple candidate sources there
    417 exists the high-level function =consult--multi=. The architecture of Consult
    418 allows it to work with different completion systems in the backend, while still
    419 offering advanced features.
    420 
    421 ** Live previews
    422 :properties:
    423 :description: Preview the currently selected candidate
    424 :custom_id: live-previews
    425 :end:
    426 #+cindex: preview
    427 
    428 Some Consult commands support live previews. For example when you scroll through
    429 the items of =consult-line=, the buffer will scroll to the corresponding position.
    430 It is possible to jump back and forth between the minibuffer and the buffer to
    431 perform recursive editing while the search is ongoing.
    432 
    433 Consult enables previews by default. You can disable them by adjusting the
    434 =consult-preview-key= variable. Furthermore it is possible to specify keybindings
    435 which trigger the preview manually as shown in the [[#use-package-example][example configuration]]. The
    436 default setting of =consult-preview-key= is =any= which means that Consult triggers
    437 the preview /immediately/ on any key press when the selected candidate changes.
    438 You can configure each command individually with its own =:preview-key=. The
    439 following settings are possible:
    440 
    441 - Automatic and immediate ='any=
    442 - Automatic and delayed =(list :debounce 0.5 'any)=
    443 - Manual and immediate ="M-."=
    444 - Manual and delayed =(list :debounce 0.5 "M-.")=
    445 - Disabled =nil=
    446 
    447 A safe recommendation is to leave automatic immediate previews enabled in
    448 general and disable the automatic preview only for commands where the preview
    449 may be expensive due to file loading. Internally, Consult uses the
    450 value of =this-command= to determine the =:preview-key=
    451 customized. This means that if you wrap a =consult-*= command within
    452 your own function or command, you will also need to add the name of
    453 /your custom command/ to the =consult-customize= call in order for it
    454 to be considered.
    455 
    456 #+begin_src emacs-lisp
    457   (consult-customize
    458    consult-ripgrep consult-git-grep consult-grep
    459    consult-bookmark consult-recent-file consult-xref
    460    consult--source-bookmark consult--source-file-register
    461    consult--source-recent-file consult--source-project-recent-file
    462    ;; my/command-wrapping-consult    ;; disable auto previews inside my command
    463    :preview-key '(:debounce 0.4 any) ;; Option 1: Delay preview
    464    ;; :preview-key "M-.")            ;; Option 2: Manual preview
    465 #+end_src
    466 
    467 In this case one may wonder what the difference is between using an Embark
    468 action on the current candidate in comparison to a manually triggered preview.
    469 The main difference is that the files opened by manual preview are closed again
    470 after the completion session. Furthermore during preview some functionality is
    471 disabled to improve the performance, see for example the customization variables
    472 =consult-preview-allowed-hooks= and =consult-preview-variables=. Files larger than
    473 =consult-preview-raw-size= are previewed literally without syntax highlighting and
    474 without changing the major mode. Delaying the preview is also useful for
    475 =consult-theme=, since the theme preview is slow. The delay results in a smoother
    476 UI experience.
    477 
    478 #+begin_src emacs-lisp
    479   ;; Preview on any key press, but delay 0.5s
    480   (consult-customize consult-theme :preview-key '(:debounce 0.5 any))
    481   ;; Preview immediately on M-., on up/down after 0.5s, on any other key after 1s
    482   (consult-customize consult-theme
    483                      :preview-key
    484                      '("M-."
    485                        :debounce 0.5 "<up>" "<down>"
    486                        :debounce 1 any))
    487 #+end_src
    488 
    489 ** Narrowing and grouping
    490 :properties:
    491 :description: Restricting the completion to a candidate group
    492 :custom_id: narrowing-and-grouping
    493 :end:
    494 #+cindex: narrowing
    495 
    496 Consult has special support for candidate groups. If the completion UI supports
    497 the grouping functionality, the UI separates the groups with thin lines and
    498 shows group titles. Grouping is useful if the list of candidates consists of
    499 candidates of multiple types or candidates from [[#multiple-sources][multiple sources]], like the
    500 =consult-buffer= command, which shows both buffers and recently opened files. Note
    501 that you can disable the group titles by setting the =:group= property of the
    502 corresponding command to nil using the =consult-customize= macro.
    503 
    504 By entering a narrowing prefix or by pressing a narrowing key it is possible to
    505 restrict the completion candidates to a certain candidate group. When you use
    506 the =consult-buffer= command, you can enter the prefix =b SPC= to restrict list of
    507 candidates to buffers only. If you press =DEL= afterwards, the full candidate list
    508 will be shown again. Furthermore a narrowing prefix key and a widening key can
    509 be configured which can be pressed to achieve the same effect, see the
    510 configuration variables =consult-narrow-key= and =consult-widen-key=.
    511 
    512 After pressing =consult-narrow-key=, the possible narrowing keys can be shown by
    513 pressing =C-h=. When pressing =C-h= after some prefix key, the =prefix-help-command=
    514 is invoked, which shows the keybinding help window by default. As a more compact
    515 alternative, there is the =consult-narrow-help= command which can be bound to a
    516 key, for example =?= or =C-h= in the =consult-narrow-map=, as shown in the [[#use-package-example][example
    517 configuration]]. If [[https://github.com/justbur/emacs-which-key][which-key]] is installed, the narrowing keys are automatically
    518 shown in the which-key window after pressing the =consult-narrow-key=.
    519 
    520 ** Asynchronous search
    521 :properties:
    522 :description: Filtering asynchronously generated candidate lists
    523 :end:
    524 #+cindex: asynchronous search
    525 
    526 Consult has support for asynchronous generation of candidate lists. This feature
    527 is used for search commands like =consult-grep=, where the list of matches is
    528 generated dynamically while the user is typing a regular expression. The grep
    529 process is executed in the background. When modifying the regular expression,
    530 the background process is terminated and a new process is started with the
    531 modified regular expression.
    532 
    533 The matches, which have been found, can then be narrowed using the installed
    534 Emacs completion-style. This can be powerful if you are using for example the
    535 =orderless= completion style.
    536 
    537 This two-level filtering is possible by splitting the input string. Part of the
    538 input string is treated as input to grep and part of the input is used for
    539 filtering. There are multiple splitting styles available, configured in
    540 ~consult-async-split-styles-alist~: =nil=, =comma=, =semicolon= and =perl=. The default
    541 splitting style is configured with the variable ~consult-async-split-style~.
    542 
    543 With the =comma= and =semicolon= splitting styles, the first word before the comma
    544 or semicolon is passed to grep, the remaining string is used for filtering. The
    545 =nil= splitting style does not perform any splitting, the whole input is passed to
    546 grep.
    547 
    548 The =perl= splitting style splits the input string at a punctuation character,
    549 using a similar syntax as Perl regular expressions.
    550 
    551 Examples:
    552 
    553 - =#defun=: Search for "defun" using grep.
    554 - =#consult embark=: Search for both "consult" and "embark" using grep in any order.
    555 - =#first.*second=: Search for "first" followed by "second" using grep.
    556 - =#\(consult\|embark\)=: Search for "consult" or "embark" using grep. Note the
    557   usage of Emacs-style regular expressions.
    558 - =#defun#consult=: Search for "defun" using grep, filter with the word
    559   "consult".
    560 - =/defun/consult=: It is also possible to use other punctuation
    561   characters.
    562 - =#to#=: Force searching for "to" using grep, since the grep pattern
    563   must be longer than =consult-async-min-input= characters by default.
    564 - =#defun -- --invert-match#=: Pass argument =--invert-match= to grep.
    565 
    566 Asynchronous processes like =find= and =grep= create an error log buffer
    567 =_*consult-async*= (note the leading space), which is useful for
    568 troubleshooting. The prompt has a small indicator showing the process status:
    569 
    570 - =:= the usual prompt colon, before input is provided.
    571 - =*= with warning face, the process is running.
    572 - =:= with success face, success, process exited with an error code of zero.
    573 - =!= with error face, failure, process exited with a nonzero error code.
    574 - =;= with error face, interrupted, for example if more input is provided.
    575 
    576 ** Multiple sources
    577 :properties:
    578 :description: Combining candidates from different sources
    579 :custom_id: multiple-sources
    580 :end:
    581 #+cindex: multiple sources
    582 
    583 Multiple synchronous candidate sources can be combined. This feature is used by
    584 the =consult-buffer= command to present buffer-like candidates in a single menu
    585 for quick access. By default =consult-buffer= includes buffers, bookmarks, recent
    586 files and project-specific buffers and files. It is possible to configure the
    587 list of sources via the =consult-buffer-sources= variable. Arbitrary custom
    588 sources can be defined.
    589 
    590 As an example, the bookmark source is defined as follows:
    591 
    592 #+begin_src emacs-lisp
    593 (defvar consult--source-bookmark
    594   `(:name     "Bookmark"
    595     :narrow   ?m
    596     :category bookmark
    597     :face     consult-bookmark
    598     :history  bookmark-history
    599     :items    ,#'bookmark-all-names
    600     :action   ,#'consult--bookmark-action))
    601 #+end_src
    602 
    603 Required source fields:
    604 - =:category= Completion category.
    605 - =:items= List of strings to select from or function returning list of strings.
    606   A list of cons cells is not supported.
    607 
    608 Optional source fields:
    609 - =:name= Name of the source, used for narrowing, group titles and annotations.
    610 - =:narrow= Narrowing character or =(character . string)= pair.
    611 - =:preview-key= Preview key or keys which trigger preview.
    612 - =:enabled= Function which must return t if the source is enabled.
    613 - =:hidden= When t candidates of this source are hidden by default.
    614 - =:face= Face used for highlighting the candidates.
    615 - =:annotate= Annotation function called for each candidate, returns string.
    616 - =:history= Name of history variable to add selected candidate.
    617 - =:default= Must be t if the first item of the source is the default value.
    618 - =:action= Function called with the selected candidate.
    619 - =:new= Function called with new candidate name, only if =:require-match= is nil.
    620 - =:state= State constructor for the source, must return the state function.
    621 - Other source fields can be added specifically to the use case.
    622 
    623 The =:state= and =:action= fields of the sources deserve a longer explanation. The
    624 =:action= function takes a single argument and is only called after selection with
    625 the selected candidate, if the selection has not been aborted. This
    626 functionality is provided for convenience and easy definition of sources. The
    627 =:state= field is more general. The =:state= function is a constructor function
    628 without arguments, which can perform some setup necessary for the preview. It
    629 must return a closure which takes an ACTION and a CANDIDATE argument. See the
    630 docstring of =consult--with-preview= for more details about the ACTION argument.
    631 
    632 By default, =consult-buffer= previews buffers, bookmarks and files. Loading recent
    633 files or bookmarks can result in expensive operations. However it is possible to
    634 configure a manual preview as follows.
    635 
    636 #+begin_src emacs-lisp
    637   (consult-customize
    638    consult--source-bookmark consult--source-file-register
    639    consult--source-recent-file consult--source-project-recent-file
    640    :preview-key "M-.")
    641 #+end_src
    642 
    643 Sources can be added directly to the =consult-buffer-source= list for convenience.
    644 For example views/perspectives can be added to the list of virtual buffers from
    645 a library like [[https://github.com/minad/bookmark-view/][bookmark-view]].
    646 
    647 #+begin_src emacs-lisp
    648 ;; Configure new bookmark-view source
    649 (add-to-list 'consult-buffer-sources
    650               (list :name     "View"
    651                     :narrow   ?v
    652                     :category 'bookmark

    656                     :items    #'bookmark-view-names)
    657               'append)
    658 
    659 ;; Modify bookmark source, such that views are hidden
    660 (setq consult--source-bookmark
    661       (plist-put

    667                                (eq #'bookmark-view-handler
    668                                    (alist-get 'handler (cdr x))))
    669                              bookmark-alist)))))
    670 #+end_src
    671 
    672 Another useful source lists all Org buffers and lets you create new ones. One
    673 can create similar sources for other major modes, e.g., for Eshell.
    674 
    675 #+begin_src emacs-lisp
    676   (defvar org-source
    677     (list :name     "Org Buffer"

    686               (insert "#+title: " name "\n\n")
    687               (org-mode)
    688               (consult--buffer-action (current-buffer))))
    689           :items
    690           (lambda ()
    691             (mapcar #'buffer-name

    693                      (lambda (x)
    694                        (eq (buffer-local-value 'major-mode x) 'org-mode))
    695                      (buffer-list))))))
    696 
    697   (add-to-list 'consult-buffer-sources 'org-source 'append)
    698 #+end_src
    699 
    700 For more details, see the documentation of =consult-buffer= and of the
    701 internal =consult--multi= API. The =consult--multi= function can be used to
    702 create new multi-source commands, but is part of the internal API as of now,
    703 since some details may still change.
    704 
    705 ** Embark integration
    706 :properties:
    707 :description: Actions, Grep/Occur-buffer export
    708 :custom_id: embark-integration
    709 :end:
    710 #+cindex: embark
    711 
    712 *NOTE*: Install the =embark-consult= package from MELPA, which provides
    713 Consult-specific Embark actions and the Occur buffer export.
    714 
    715 Embark is a versatile package which offers context dependent actions, comparable
    716 to a context menu. See the [[https://github.com/oantolin/embark][Embark manual]] for an extensive description of its
    717 capabilities.
    718 
    719 Actions are commands which can operate on the currently selected candidate (or
    720 target in Embark terminology). When completing files, for example the
    721 =delete-file= command is offered. With Embark you can execute arbitrary commands
    722 on the currently selected candidate via =M-x=.
    723 
    724 Furthermore Embark provides the =embark-collect= command, which collects
    725 candidates and presents them in an Embark collect buffer, where further actions
    726 can be applied to them. A related feature is the =embark-export= command, which
    727 exports candidate lists to a buffer of a special type. For example in the case
    728 of file completion, a Dired buffer is opened.
    729 
    730 In the context of Consult, particularly exciting is the possibility to export
    731 the matching lines from =consult-line=, =consult-outline=, =consult-mark= and
    732 =consult-global-mark=. The matching lines are exported to an Occur buffer where
    733 they can be edited via the =occur-edit-mode= (press key =e=). Similarly, Embark
    734 supports exporting the matches found by =consult-grep=, =consult-ripgrep= and
    735 =consult-git-grep= to a Grep buffer, where the matches across files can be edited,
    736 if the [[https://github.com/mhayashi1120/Emacs-wgrep][wgrep]] package is installed. These three workflows are symmetric.
    737 
    738 + =consult-line= -> =embark-export= to =occur-mode= buffer -> =occur-edit-mode= for editing of matches in buffer.
    739 + =consult-grep= -> =embark-export= to =grep-mode= buffer -> =wgrep= for editing of all matches.

    744 :description: Example configuration and customization variables
    745 :end:
    746 
    747 Consult can be installed from [[https://elpa.gnu.org/packages/consult.html][ELPA]] or [[https://melpa.org/#/consult][MELPA]] via the Emacs built-in package
    748 manager. Alternatively it can be directly installed from the development
    749 repository via other non-standard package managers.
    750 
    751 There is the [[https://github.com/minad/consult/wiki][Consult wiki]], where additional configuration examples can be
    752 contributed.
    753 
    754 *IMPORTANT:* It is strongly recommended that you enable [[https://www.gnu.org/software/emacs/manual/html_node/elisp/Lexical-Binding.html][lexical binding]] in your
    755 configuration. Consult relies on lambdas and lexical closures. For this reason
    756 many Consult-related snippets require lexical binding.
    757 
    758 ** Use-package example

    764 
    765 The Consult package only provides commands and does not add any keybindings or
    766 modes. Therefore the package is non-intrusive but requires a little setup
    767 effort. In order to use the Consult commands, it is advised to add keybindings
    768 for commands which are accessed often. Rarely used commands can be invoked via
    769 =M-x=. Feel free to only bind the commands you consider useful to your workflow.
    770 The configuration shown here relies on the =use-package= macro, which is a
    771 convenient tool to manage package configurations.
    772 
    773 *NOTE:* There is the [[https://github.com/minad/consult/wiki][Consult wiki]], where you can contribute additional

    951 ** Fine-tuning of individual commands
    952 :properties:
    953 :alt_title: Fine-tuning
    954 :description: Fine-grained configuration for special requirements
    955 :end:
    956 
    957 *NOTE:* Consult supports fine-grained customization of individual commands. This
    958 configuration feature exists for experienced users with special requirements.
    959 There is the [[https://github.com/minad/consult/wiki][Consult wiki]], where we collect further configuration examples.
    960 
    961 Commands and buffer sources allow flexible, individual customization by using
    962 the =consult-customize= macro. You can override any option passed to the internal
    963 =consult--read= API. The [[https://github.com/minad/consult/wiki][Consult wiki]] already contains a numerous useful
    964 configuration examples. Note that since =consult--read= is part of the internal
    965 API, options could be removed, replaced or renamed in future versions of the
    966 package.
    967 
    968 Useful options are:
    969 - =:prompt= set the prompt string
    970 - =:preview-key= set the preview key, default is =consult-preview-key=
    971 - =:initial= set the initial input
    972 - =:default= set the default value
    973 - =:history= set the history variable symbol
    974 - =:add-history= add items to the future history, for example symbol at point
    975 - =:sort= enable or disable sorting
    976 - =:group= set to nil to disable candidate grouping and titles.
    977 - =:inherit-input-method= set to non-nil to inherit the input method.
    978 
    979 #+begin_src emacs-lisp
    980   (consult-customize
    981    ;; Disable preview for `consult-theme' completely.
    982    consult-theme :preview-key nil
    983    ;; Set preview for `consult-buffer' to key `M-.'
    984    consult-buffer :preview-key "M-."
    985    ;; For `consult-line' change the prompt and specify multiple preview
    986    ;; keybindings. Note that you should bind <S-up> and <S-down> in the
    987    ;; `minibuffer-local-completion-map' or `vertico-map' to the commands which
    988    ;; select the previous or next candidate.
    989    consult-line :prompt "Search: "
    990    :preview-key '("S-<down>" "S-<up>"))
    991 #+end_src
    992 
    993 The configuration values are evaluated at runtime, just before the completion
    994 session is started. Therefore you can use for example =thing-at-point= to adjust
    995 the initial input or the future history.
    996 
    997 #+begin_src emacs-lisp
    998   (consult-customize
    999    consult-line
   1000    :add-history (seq-some #'thing-at-point '(region symbol)))
   1001 
   1002   (defalias 'consult-line-thing-at-point 'consult-line)
   1003 
   1004   (consult-customize
   1005    consult-line-thing-at-point
   1006    :initial (thing-at-point 'symbol))
   1007 #+end_src
   1008 
   1009 Generally it is possible to modify commands for your individual needs by the
   1010 following techniques:
   1011 
   1012 1. Use =consult-customize= in order to change the command or source settings.
   1013 2. Create your own wrapper function which passes modified arguments to the Consult functions.
   1014 3. Create your own buffer [[#multiple-sources][multi sources]] for =consult-buffer=.
   1015 4. Create advices to modify some internal behavior.
   1016 5. Write or propose a patch.
   1017

   1035 - The builtin completion UI, which pops up the =*Completions*= buffer.
   1036 - The builtin =icomplete-vertical-mode= in Emacs 28.
   1037 - [[https://git.sr.ht/~protesilaos/mct][mct by Protesilaos Stavrou]]: Minibuffer and Completions in Tandem, which builds
   1038   on the default completion UI (development currently [[https://protesilaos.com/codelog/2022-04-14-emacs-discontinue-mct/][discontinued]]).
   1039 
   1040 Note that all packages are independent and can be exchanged with alternative
   1041 components, since there exist no hard dependencies. Furthermore it is possible
   1042 to get started with only default completion and Consult and add more components
   1043 later to the mix. For example you can omit Marginalia if you don't need
   1044 annotations. I highly recommend the Embark package, but in order to familiarize
   1045 yourself with the other components, you can first start without it - or you could
   1046 use with Embark right away and add the other components later on.

   1092 * Bug reports
   1093 :properties:
   1094 :description: How to create reproducible bug reports
   1095 :end:
   1096 
   1097 If you find a bug or suspect that there is a problem with Consult, please carry
   1098 out the following steps:
   1099 
   1100 1. *Search through the issue tracker* if your issue has been reported before (and
   1101    has been resolved eventually) in the meantime.
   1102 2. *Remove all packages involved in the suspected bug from your installation.*
   1103 3. *Reinstall the newest version of all relevant packages*. Updating alone is not
   1104    sufficient, since package.el is known to cause miscompilation. The list of
   1105    packages includes Consult, Compat, Vertico or other completion UIs,
   1106    Marginalia, Embark and Orderless.
   1107 4. Either use the default completion UI or ensure that exactly one of
   1108    =vertico-mode=, =mct-mode=, or =icomplete-mode= is enabled. The unsupported modes
   1109    =selectrum-mode=, =ivy-mode=, =helm-mode=, =ido-mode= and =ido-ubiquitous-mode= must be
   1110    disabled.
   1111 5. Ensure that the =completion-styles= variable is properly configured. Try to set
   1112    =completion-styles= to a list including =substring= or =orderless=.
   1113 6. Try to reproduce the issue by starting a bare bone Emacs instance with =emacs -Q=
   1114    on the command line. Execute the following minimal code snippets in the
   1115    scratch buffer. This way we can exclude side effects due to configuration
   1116    settings. If other packages are relevant to reproduce the issue, include them
   1117    in the minimal configuration snippet.
   1118 
   1119 Minimal setup with Vertico for =emacs -Q=:
   1120 #+begin_src emacs-lisp
   1121 (package-initialize)
   1122 (require 'consult)
   1123 (require 'vertico)
   1124 (vertico-mode)
   1125 (setq completion-styles '(substring basic))
   1126 #+end_src
   1127 
   1128 Minimal setup with the default completion system for =emacs -Q=:
   1129 #+begin_src emacs-lisp
   1130 (package-initialize)
   1131 (require 'consult)
   1132 (setq completion-styles '(substring basic))
   1133 #+end_src
   1134 
   1135 Please provide the necessary important information with your bug report:
   1136 
   1137 - The minimal configuration snippet used to reproduce the issue.
   1138 - Your completion UI (Default completion, Vertico, Mct or Icomplete).
   1139 - A stack trace in case the bug triggers an exception.
   1140 - Your Emacs version, since bugs may be fixed or introduced in newer versions.
   1141 - Your operating system, since Emacs behavior varies between Linux, Mac and
   1142   Windows.
   1143 - The package manager, e.g., straight.el or package.el, used to install
   1144   the Emacs packages, in order to exclude update issues. Did you install
   1145   Consult as part of the Doom or Spacemacs Emacs distributions?
   1146 - Do you use Evil or other packages which apply deep changes?
   1147   Consult does not provide Evil integration out of the box, but there is some
   1148   support in [[https://github.com/emacs-evil/evil-collection][evil-collection]].
   1149 
   1150 When evaluating Consult-related code snippets you should enable [[https://www.gnu.org/software/emacs/manual/html_node/elisp/Lexical-Binding.html][lexical binding]].
   1151 Consult often relies on lambdas and lexical closures.
