 1 Introduction
 **************
 
 Corfu enhances completion at point with a small completion popup.  The
 current candidates are shown in a popup below or above the point.  Corfu
 is the minimalistic ‘completion-in-region’ counterpart of the Vertico
 (https://github.com/minad/vertico) minibuffer UI.
 
    Corfu is a small package, which relies on the Emacs completion
 facilities and concentrates on providing a polished completion UI.
 Completions are either provided by commands like ‘dabbrev-completion’ or
 by pluggable backends (‘completion-at-point-functions’, Capfs).  Most
 programming language major modes implement a Capf.  Furthermore the
 language server packages, Eglot (https://github.com/joaotavora/eglot)
 and Lsp-mode (https://github.com/emacs-lsp/lsp-mode), use Capfs which
 talk to the LSP server to retrieve the completions.  Corfu does not
 include its own completion backends.  The Emacs built-in Capfs and the
 Capfs provided by other programming language packages are usually
 sufficient.  A few additional Capfs and completion utilities are
 provided by the Cape (https://github.com/minad/cape) package.
 
    *NOTE*: Corfu uses child frames to show the popup and falls back to
 the default setting of the ‘completion-in-region-function’ on
 non-graphical displays.  There is a package in the works
 (https://codeberg.org/akib/emacs-corfu-popup) which uses overlays for
 the popup such that Corfu can be used when Emacs is running in a
 terminal.

 3 Installation and Configuration
 ********************************
 
 Corfu is available from GNU ELPA
 (http://elpa.gnu.org/packages/corfu.html), such that it can be installed
 directly via ‘package-install’.  After installation, the global minor
 mode can be enabled with ‘M-x global-corfu-mode’.  In order to configure
 Corfu and other packages in your init.el, you may want to use
 ‘use-package’.
 
    Corfu is highly flexible and customizable via ‘corfu-*’ customization
 variables, such that you can adapt it precisely to your requirements.
 However in order to quickly try out the Corfu completion package, it
 should be sufficient to activate ‘global-corfu-mode’.  You can
 experiment with manual completion for example in an Elisp buffer or in
 an Eshell or Shell buffer.  For auto completion, set ‘corfu-auto=t’
 before turning on ‘global-corfu-mode’.
 
    Here is an example configuration:
 
      (use-package corfu
        ;; Optional customizations
        ;; :custom
        ;; (corfu-cycle t)                ;; Enable cycling for `corfu-next/previous'
        ;; (corfu-auto t)                 ;; Enable auto completion
        ;; (corfu-separator ?\s)          ;; Orderless field separator
        ;; (corfu-quit-at-boundary nil)   ;; Never quit at completion boundary
        ;; (corfu-quit-no-match nil)      ;; Never quit, even if there is no match
        ;; (corfu-preview-current nil)    ;; Disable current candidate preview
        ;; (corfu-preselect-first nil)    ;; Disable candidate preselection
        ;; (corfu-on-exact-match nil)     ;; Configure handling of exact matches
        ;; (corfu-echo-documentation nil) ;; Disable documentation in the echo area
        ;; (corfu-scroll-margin 5)        ;; Use scroll margin
 
        ;; Enable Corfu only for certain modes.
        ;; :hook ((prog-mode . corfu-mode)
        ;;        (shell-mode . corfu-mode)
        ;;        (eshell-mode . corfu-mode))
 
        ;; Recommended: Enable Corfu globally.
        ;; This is recommended since Dabbrev can be used globally (M-/).
        ;; See also `corfu-excluded-modes'.
        :init
        (global-corfu-mode))
 
      ;; A few more useful configurations...
      (use-package emacs
        :init
        ;; TAB cycle if there are only few candidates
        (setq completion-cycle-threshold 3)
 
        ;; Emacs 28: Hide commands in M-x which do not apply to the current mode.
        ;; Corfu commands are hidden, since they are not supposed to be used via M-x.
        ;; (setq read-extended-command-predicate
        ;;       #'command-completion-default-include-p)
 
        ;; Enable indentation+completion using the TAB key.
        ;; `completion-at-point' is often bound to M-TAB.
        (setq tab-always-indent 'complete))
 
    Dabbrev completion is based on ‘completion-in-region’ and can be used
 with Corfu.  You may want to swap the ‘dabbrev-completion’ with the
 ‘dabbrev-expand’ key for easier access, if you prefer completion.  Also
 take a look at the ‘cape-dabbrev’ completion at point function provided
 by my Cape (https://github.com/minad/cape) package.
 
      ;; Use Dabbrev with Corfu!
      (use-package dabbrev
        ;; Swap M-/ and C-M-/
        :bind (("M-/" . dabbrev-completion)
               ("C-M-/" . dabbrev-expand))
        ;; Other useful Dabbrev configurations.
        :custom
        (dabbrev-ignored-buffer-regexps '("\\.\\(?:pdf\\|jpe?g\\|png\\)\\'")))
 
    If you start to configure the package more deeply, I recommend to
 give the Orderless completion style a try for filtering.  Orderless
 completion is different from the familiar prefix TAB completion.  Corfu
 can be used with the default completion styles.  The use of Orderless is
 not a necessity.
 
      ;; 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))))))
 
    The ‘basic’ completion style is specified as fallback in addition to
 ‘orderless’ in order to ensure that completion commands which rely on
 dynamic completion tables, e.g., ‘completion-table-dynamic’ or
 ‘completion-table-in-turn’, work correctly.  See ‘+orderless-dispatch’
 in the Consult wiki (https://github.com/minad/consult/wiki) for an
 advanced Orderless style dispatcher.  Additionally enable
 ‘partial-completion’ for file path expansion.  ‘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 give the
 ‘initials’ completion style a try.
 
    See also the Corfu Wiki (https://github.com/minad/corfu/wiki) for
 additional configuration tips.  In particular the Lsp-mode configuration
 is documented in the wiki.  For more general documentation read the
 chapter about completion in the Emacs manual
 (https://www.gnu.org/software/emacs/manual/html_node/emacs/Completion.html).
 If you want to create your own Capfs, you can find documentation about
 completion in the Elisp manual
 (https://www.gnu.org/software/emacs/manual/html_node/elisp/Completion.html).

 3.1 Auto completion
 ===================
 
 Auto completion is disabled by default, but can be enabled by setting
 ‘corfu-auto=t’.  Furthermore you may want to configure Corfu to quit
 completion eagerly, such that the completion popup stays out of your way
 when it appeared unexpectedly.
 
      ;; Enable auto completion and configure quitting
      (setq corfu-auto t
            corfu-quit-no-match 'separator) ;; or t
 
    In general, I recommend to experiment a bit with the various settings
 and key bindings to find a configuration which works for you.  There is
 no one size fits all solution.  Some people like auto completion, some
 like manual completion, some want to cycle with TAB and some with the
 arrow keys...

 3.2 Completing with Corfu in the minibuffer
 ===========================================
 
 Corfu can be used for completion in the minibuffer, since it relies on
 child frames to display the candidates.  By default, ‘global-corfu-mode’
 does not activate ‘corfu-mode’ in the minibuffer, to avoid interference
 with specialised minibuffer completion UIs like Vertico or Mct.  However
 you may still want to enable Corfu completion for commands like ‘M-:’
 (‘eval-expression’) or ‘M-!’ (‘shell-command’), which read from the
 minibuffer.  Activate ‘corfu-mode’ only if ‘completion-at-point’ is
 bound in the minibuffer-local keymap to achieve this effect.
 
      (defun corfu-enable-in-minibuffer ()
        "Enable Corfu in the minibuffer if `completion-at-point' is bound."
        (when (where-is-internal #'completion-at-point (list (current-local-map)))
          ;; (setq-local corfu-auto nil) Enable/disable auto completion
          (corfu-mode 1)))
      (add-hook 'minibuffer-setup-hook #'corfu-enable-in-minibuffer)
 
    You can also enable Corfu more generally for every minibuffer, as
 long as no other completion UI is active.  If you use Mct or Vertico as
 your main minibuffer completion UI, the following snippet should yield
 the desired result.
 
      (defun corfu-enable-always-in-minibuffer ()
        "Enable Corfu in the minibuffer if Vertico/Mct are not active."
        (unless (or (bound-and-true-p mct--active)
                    (bound-and-true-p vertico--input))
          ;; (setq-local corfu-auto nil) Enable/disable auto completion
          (corfu-mode 1)))
      (add-hook 'minibuffer-setup-hook #'corfu-enable-always-in-minibuffer 1)
 
 
 File: corfu.info,  Node: Completing with Corfu in the Eshell or Shell,  Next: Orderless completion,  Prev: Completing with Corfu in the minibuffer,  Up: Installation and Configuration
 
 3.3 Completing with Corfu in the Eshell or Shell
 ================================================
 
 When completing in the Eshell I recommend conservative local settings
 without auto completion, such that the completion behavior is similar to
 widely used shells like Bash, Zsh or Fish.
 
      (add-hook 'eshell-mode-hook
                (lambda ()
                  (setq-local corfu-auto nil)
                  (corfu-mode)))
 
    When pressing ‘RET’ while the Corfu popup is visible, the
 ‘corfu-insert’ command will be invoked.  This command does inserts the
 currently selected candidate, but it does not send the prompt input to
 Eshell or the comint process.  Therefore you often have to press ‘RET’
 twice which feels like an unnecessary double confirmation.  Fortunately
 it is easy to improve this!  In my configuration I define the advice
 ‘corfu-send-shell’ which sends the candidate after insertion.
 
      (defun corfu-send-shell (&rest _)
        "Send completion candidate when inside comint/eshell."
        (cond
         ((and (derived-mode-p 'eshell-mode) (fboundp 'eshell-send-input))
          (eshell-send-input))
         ((and (derived-mode-p 'comint-mode)  (fboundp 'comint-send-input))
          (comint-send-input))))
 
      (advice-add #'corfu-insert :after #'corfu-send-shell)
 
    Shell completion uses the flexible ‘pcomplete’ mechanism internally,
 which allows you to program the completions per shell command.  If you
 want to know more, look into this blog post
 (https://www.masteringemacs.org/article/pcomplete-context-sensitive-completion-emacs),
 which shows how to configure pcomplete for git commands.  I recommend
 the pcmpl-args (https://github.com/JonWaltman/pcmpl-args.el) package
 which extends Pcomplete with completion support and helpful annotation
 support for more commands.  Similar to the Fish shell, pcmpl-args uses
 man page parsing and –help output parsing to dynamically generate
 completions.  This package brings Eshell completion to another level!
 
    Unfortunately Pcomplete has a few technical issues, which we can work
 around with the Cape (https://github.com/minad/cape) library (Completion
 at point extensions).  Cape provides wrappers, which sanitize the
 pcomplete function.  Ideally the bugs in pcomplete should be fixed
 upstream.  *For now these two advices are strongly recommended to
 achieve a sane Eshell experience.*
 
      ;; Silence the pcomplete capf, no errors or messages!
      (advice-add 'pcomplete-completions-at-point :around #'cape-wrap-silent)
 
      ;; Ensure that pcomplete does not write to the buffer
      ;; and behaves as a pure `completion-at-point-function'.
      (advice-add 'pcomplete-completions-at-point :around #'cape-wrap-purify)
 
 
 File: corfu.info,  Node: Orderless completion,  Next: TAB-and-Go completion,  Prev: Completing with Corfu in the Eshell or Shell,  Up: Installation and Configuration
 
 3.4 Orderless completion
 ========================
 
 Orderless (https://github.com/oantolin/orderless) is an advanced
 completion style that supports multi-component search filters separated
 by a configurable character (space, by default).  Normally, entering
 characters like space which lie outside the completion region boundaries
 (words, typically) causes Corfu to quit.  This behavior is helpful with
 auto-completion, which may pop-up when not desired, e.g.  on entering a
 new variable name.  Just keep typing and Corfu will get out of the way.
 
    But orderless search terms can contain arbitrary characters; they are
 also interpreted as regular expressions.  To use orderless, set
 ‘corfu-separator’ (a space, by default) to the primary character of your
 orderless component separator.
 
    Then, when a new orderless component is desired, use ‘M-SPC’
 (‘corfu-insert-separator’) to enter the _first_ component separator in
 the input, and arbitrary orderless search terms and new separators can
 be entered thereafter.
 
    To treat the entire input as Orderless input, you can set the
 customization option ‘corfu-quit-at-boundary=t’.  This disables the
 predicate which checks if the current completion boundary has been left.
 In contrast, if you _always_ want to quit at the boundary, simply set
 ‘corfu-quit-at-boundary=nil’.  By default ‘corfu-quit-at-boundary’ is
 set to ‘separator’ which quits at completion boundaries as long as no
 separator has been inserted with ‘corfu-insert-separator’.
 
    Finally, there exists the user option ‘corfu-quit-no-match’ which is
 set to ‘separator’ by default.  With this setting Corfu stays alive as
 soon as you start advanced filtering with a ‘corfu-separator’ even if
 there are no matches, for example due to a typo.  As long as no
 separator character has been inserted with ‘corfu-insert-separator’,
 Corfu will still quit if there are no matches.  This ensures that the
 Corfu popup goes away quickly if completion is not possible.
 
    In the following we show two configurations, one which works best
 with auto completion and one which may work better with manual
 completion if you prefer to always use ‘SPC’ to separate the Orderless
 components.
 
      ;; Auto completion example
      (use-package corfu
        :custom
        (corfu-auto t)          ;; Enable auto completion
        ;; (corfu-separator ?_) ;; Set to orderless separator, if not using space
        :bind
        ;; Another key binding can be used, such as S-SPC.
        ;; (:map corfu-map ("M-SPC" . corfu-insert-separator))
        :init
        (global-corfu-mode))
 
      ;; Manual completion example
      (use-package corfu
        :custom
        ;; (corfu-separator ?_) ;; Set to orderless separator, if not using space
        :bind
        ;; Configure SPC for separator insertion
        (:map corfu-map ("SPC" . corfu-insert-separator))
        :init
        (global-corfu-mode))

 3.5 TAB-and-Go completion
 =========================
 
 You may be interested in configuring Corfu in TAB-and-Go style.
 Pressing TAB moves to the next candidate and further input will then
 commit the selection.  Note that further input will not expand snippets
 or templates, which may not be desired but which leads overall to a more
 predictable behavior.  In order to force snippet expansion, confirm a
 candidate explicitly with ‘RET’.
 
      (use-package corfu
        ;; TAB-and-Go customizations
        :custom
        (corfu-cycle t)             ;; Enable cycling for `corfu-next/previous'
        (corfu-preselect-first nil) ;; Disable candidate preselection
 
        ;; Use TAB for cycling, default is `corfu-complete'.
        :bind
        (:map corfu-map
              ("TAB" . corfu-next)
              ([tab] . corfu-next)
              ("S-TAB" . corfu-previous)
              ([backtab] . corfu-previous))
 
        :init
        (global-corfu-mode))
 
 
 File: corfu.info,  Node: Transfer completion to the minibuffer,  Prev: TAB-and-Go completion,  Up: Installation and Configuration
 
 3.6 Transfer completion to the minibuffer
 =========================================
 
 Sometimes it is useful to transfer the Corfu completion session to the
 minibuffer, since the minibuffer offers richer interaction features.  In
 particular, Embark (https://github.com/oantolin/embark) is available in
 the minibuffer, such that you can act on the candidates or
 export/collect the candidates to a separate buffer.  Hopefully we can
 also add Corfu-support to Embark in the future, such that at least
 export/collect is possible directly from Corfu.  But in my opinion
 having the ability to transfer the Corfu completion to the minibuffer is
 an even better feature, since further completion can be performed there.
 
    The command ‘corfu-move-to-minibuffer’ is defined here in terms of
 ‘consult-completion-in-region’, which uses the minibuffer completion UI
 via ‘completing-read’.
 
      (defun corfu-move-to-minibuffer ()
        (interactive)
        (let ((completion-extra-properties corfu--extra)
              completion-cycle-threshold completion-cycling)
          (apply #'consult-completion-in-region completion-in-region--data)))
      (define-key corfu-map "\M-m" #'corfu-move-to-minibuffer)

 4 Key bindings
 **************
 
 Corfu uses a transient keymap ‘corfu-map’ which is active while the
 popup is shown.  The keymap defines the following remappings and
 bindings:
 
    • ‘beginning-of-buffer’ -> ‘corfu-first’
    • ‘end-of-buffer’ -> ‘corfu-last’
    • ‘scroll-down-command’ -> ‘corfu-scroll-down’
    • ‘scroll-up-command’ -> ‘corfu-scroll-up’
    • ‘next-line’, ‘down’, ‘M-n’ -> ‘corfu-next’
    • ‘previous-line’, ‘up’, ‘M-p’ -> ‘corfu-previous’
    • ‘completion-at-point’, ‘TAB’ -> ‘corfu-complete’
    • ‘RET’ -> ‘corfu-insert’
    • ‘M-g’ -> ‘corfu-info-location’
    • ‘M-h’ -> ‘corfu-info-documentation’
    • ‘M-SPC’ -> ‘corfu-insert-separator’

 5 Extensions
 ************
 
 We maintain small extension packages to Corfu in this repository in the
 subdirectory extensions/
 (https://github.com/minad/corfu/tree/main/extensions).  The extensions
 are installed together with Corfu 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 ‘corfu.el’ and the ‘corfu-*.el’ extensions.  Currently
 the following extensions come with the Corfu ELPA package:
 
    • corfu-history
      (https://github.com/minad/corfu/blob/main/extensions/corfu-history.el):
      ‘corfu-history-mode’ to remember selected candidates and to improve
      sorting.
    • corfu-indexed
      (https://github.com/minad/corfu/blob/main/extensions/corfu-indexed.el):
      ‘corfu-indexed-mode’ to select indexed candidates with prefix
      arguments.
    • corfu-info
      (https://github.com/minad/corfu/blob/main/extensions/corfu-info.el):
      Candidate actions to access the candidate location and
      documentation.
    • corfu-quick
      (https://github.com/minad/corfu/blob/main/extensions/corfu-quick.el):
      Commands to select using Avy-style quick keys.

 6 Complementary packages
 ************************
 
 Corfu works well together with all packages providing code completion
 via the ‘completion-at-point-functions’.  Many modes and packages
 already provide a Capf out of the box.  Nevertheless you may want to
 look into complementary packages to enhance your setup.
 
    • Orderless (https://github.com/oantolin/orderless): Corfu supports
      completion styles, including the advanced Orderless
      (https://github.com/oantolin/orderless) completion style, where the
      filtering expressions are separated by spaces or another character
      (see ‘corfu-separator’).
 
    • Cape (https://github.com/minad/cape): Additional Capf backends and
      ‘completion-in-region’ commands are provided by the Cape
      (https://github.com/minad/cape) package.  Among others, the package
      supplies a file path and a dabbrev completion backend.  Cape
      provides the ‘cape-company-to-capf’ adapter to reuse Company
      backends in Corfu.  Furthermore the function ‘cape-super-capf’ can
      merge multiple Capfs, such that the candidates of multiple Capfs
      are displayed together at the same time.
 
    • kind-icon (https://github.com/jdtsmith/kind-icon): Icons are
      supported by Corfu via an external package.  For example the
      kind-icon (https://github.com/jdtsmith/kind-icon) package provides
      beautifully styled SVG icons based on monochromatic icon sets like
      material design.
 
    • corfu-doc (https://github.com/galeo/corfu-doc): The corfu-doc
      package displays the candidate documentation in a popup next to the
      Corfu popup, similar to ‘company-quickhelp’.
 
    • pcmpl-args (https://github.com/JonWaltman/pcmpl-args.el): Extend
      the Eshell/Shell Pcomplete mechanism with support for many more
      commands.  Similar to the Fish shell, Pcomplete uses man page
      parsing to dynamically retrieve the completions and helpful
      annotations.  This package brings Eshell completions to another
      level!
 
    • Tempel (https://github.com/minad/tempel): Tiny template/snippet
      package with templates in Lisp syntax, which can be used in
      conjunction with Corfu.
 
    • Vertico (https://github.com/minad/vertico): You may also want to
      look into my Vertico (https://github.com/minad/vertico) package.
      Vertico is the minibuffer completion counterpart of Corfu.

    • Company (https://github.com/company-mode/company-mode): Company is
      a widely used and mature completion package, which implements a
      similar interaction model and popup UI as Corfu.  While Corfu
      relies exclusively on the standard Emacs completion API (Capfs),
      Company defines its own API for the backends.  Company includes its
      completion backends, which are incompatible with the Emacs
      completion infrastructure.  As a result of this design, Company is
      a more complex package than Corfu.  Company by default uses
      overlays for the popup in contrast to the child frames used by
      Corfu.  Overall both packages work well, but Company integrates
      less tightly with Emacs.  The ‘completion-styles’ support is more
      limited and the ‘completion-at-point’ command and the
      ‘completion-in-region’ function do not invoke Company.
 
    • Mct (https://git.sr.ht/~protesilaos/mct): Protesilaos’ Minibuffer
      Confines Transcended package supports both minibuffer completion
      and completion in region.  It reuses the default completion UI for
      this purpose and installs a timer which live updates the completion
      buffer.  The main advantage of Mct is that you work with a regular
      Emacs buffer instead of with a popup.  You can take advantage of
      the usual Emacs commands to navigate in the completions buffer.  On
      top, Mct enhances the movement such that you can quickly switch
      between the completions buffer and the minibuffer or the region
      which is being completed.  Mct does not support timer-based auto
      completion, but the integration into Emacs is naturally tight.
 
    • consult-completion-in-region (https://github.com/minad/consult):
      The Consult package provides the function
      ‘consult-completion-in-region’ which can be set as
      ‘completion-in-region-function’ such that it handles
      ‘completion-at-point’.  The function works by transferring the
      in-buffer completion to the minibuffer.  In the minibuffer, the
      minibuffer completion UI, for example Vertico
      (https://github.com/minad/vertico) takes over.  If you prefer to
      perform all your completions in the minibuffer
      ‘consult-completion-in-region’ is your best option.
