+* Ivy Generic Help
+
+=ivy= is an Emacs incremental completion framework.
+
+- Narrow the list by typing some pattern,
+- Multiple patterns are allowed by separating with a space,
+- Select with ~C-n~ and ~C-p~, choose with ~RET~.
+
+** Help
+
+- ~C-h m~ :: Pop to this generic help buffer.
+
+** Basic Operations
+*** Key bindings for navigation
+
+- ~C-n~ (=ivy-next-line=) :: next candidate.
+- ~C-p~ (=ivy-previous-line=) :: previous candidate.
+- ~C-v~ (=ivy-scroll-up-command=) :: next page.
+- ~M-v~ (=ivy-scroll-down-command=) :: previous page.
+- ~M-<~ (=ivy-beginning-of-buffer=) :: first candidate.
+- ~M->~ (=ivy-end-of-buffer=) :: last candidate.
+
+*** Key bindings for single selection
+
+When selecting a candidate, an action is called on it. You can think
+of an action as a function that takes the selected candidate as an
+argument and does something with it.
+
+Ivy can offer several actions from which to choose. This can be
+independently composed with whether you want to end completion when
+the action is called. Depending on this, the short term is either
+"calling an action" or "exiting with action".
+
+~C-m~ or ~RET~ (=ivy-done=) - exit with the current action.
+
+~M-o~ (=ivy-dispatching-done=) - select an action and exit with it.
+
+~C-j~ (=ivy-alt-done=) - when the candidate is a directory, enter
+it. Otherwise, exit with the current action.
+
+~TAB~ (=ivy-partial-or-done=) - attempt partial completion, extending
+the current input as much as possible. ~TAB TAB~ is the same as ~C-j~.
+
+~C-M-j~ (=ivy-immediate-done=) - exit with the current action, calling
+it on the /current input/ instead of the current candidate. This is
+useful especially when creating new files or directories - often the
+input will match an existing file, which you don't want to select.
+
+~C-'~ (=ivy-avy=) - select a candidate from the current page with avy
+and exit with the current action.
+
+** Advanced Operations
+*** Key bindings for multiple selection
+
+For repeatedly applying multiple actions or acting on multiple
+candidates, Ivy does not close the minibuffer between commands. It
+keeps the minibuffer open for applying subsequent actions.
+
+Adding an extra meta key to the normal key chord invokes the special
+version of the regular commands that enables applying multiple
+actions.
+
+~C-M-m~ (=ivy-call=) is the non-exiting version of ~C-m~ (=ivy-done=).
+
+~C-M-n~ (=ivy-next-line-and-call=) combines ~C-n~ and ~C-M-m~.
+
+~C-M-p~ (=ivy-previous-line-and-call=) combines ~C-p~ and ~C-M-m~.
+
+~C-M-o~ (=ivy-dispatching-call=) is a non-exiting version of ~M-o~
+(=ivy-dispatching-done=).
+
+*** Key bindings that alter the minibuffer input
+
+~M-n~ (=ivy-next-history-element=) select the next history element or
+symbol/URL at point.
+
+~M-p~ (=ivy-previous-history-element=) select the previous history
+element.
+
+~C-r~ (=ivy-reverse-i-search=) start a recursive completion session to
+select a history element.
+
+~M-i~ (=ivy-insert-current=) insert the current candidate into the
+minibuffer. Useful for copying and renaming files, for example: ~M-i~
+to insert the original file name string, edit it, and then ~C-m~ to
+complete the renaming.
+
+~M-j~ (=ivy-yank-word=) insert the sub-word at point into the
+minibuffer.
+
+~S-SPC~ (=ivy-restrict-to-matches=) deletes the current input, and
+resets the candidates list to the currently restricted matches. This
+is how Ivy provides narrowing in successive tiers.
+
+*** Other key bindings
+
+~M-w~ (=ivy-kill-ring-save=) copies the selected candidates to the
+kill ring; when the region is active, copies the active region.
+
+*** Saving the current completion session to a buffer
+
+~C-c C-o~ (=ivy-occur=) saves the current candidates to a new buffer;
+the list is active in the new buffer.
+
+~RET~ or ~mouse-1~ in the new buffer calls the appropriate action on
+the selected candidate.
+
+Ivy has no limit on the number of active buffers like these.
+
+Ivy takes care of making these buffer names unique. It applies
+descriptive names, for example: =*ivy-occur counsel-describe-variable
+"function$*=.
+
+*** Global key bindings
+
+=ivy-resume= recalls the state of the completion session just before
+its last exit. Useful after an accidental ~C-m~ (=ivy-done=).
+Recommended global binding: ~C-c C-r~.
+
+*** Hydra in the minibuffer
+
+~C-o~ (=hydra-ivy/body=) invokes Hydra menus with key shortcuts.
+
+When in Hydra, ~C-o~ or ~i~ resumes editing.
+
+Hydra reduces key strokes, for example: ~C-n C-n C-n C-n~ is ~C-o
+jjjj~ in Hydra. Besides certain shorter keys, Hydra shows useful info
+such as case folding and the current action.
+
+Additionally, here are the keys that are otherwise not bound:
+
+- ~<~ and ~>~ adjust the height of the minibuffer.
+- ~c~ (=ivy-toggle-calling=) - toggle calling the current action each
+  time a different candidate is selected.
+- ~m~ (=ivy-rotate-preferred-builders=) - rotate regex matcher.
+- ~w~ and ~s~ scroll the actions list.
+
+Minibuffer editing is disabled when Hydra is active.

+;;; Commentary:
+
+;; This package provides `ivy-read' as an alternative to
+;; `completing-read' and similar functions.
+;;
+;; There's no intricate code to determine the best candidate.
+;; Instead, the user can navigate to it with `ivy-next-line' and
+;; `ivy-previous-line'.
+;;
+;; The matching is done by splitting the input text by spaces and
+;; re-building it into a regex.
+;; So "for example" is transformed into "\\(for\\).*\\(example\\)".

+
+   Ivy is an interactive interface for completion in Emacs.  Emacs uses
+completion mechanism in a variety of contexts: code, menus, commands,
+variables, functions, etc.  Completion entails listing, sorting,
+filtering, previewing, and applying actions on selected items.  When
+active, ‘ivy-mode’ completes the selection process by narrowing
+available choices while previewing in the minibuffer.  Selecting the
+final candidate is either through simple keyboard character inputs or
+through powerful regular expressions.

+1 Introduction
+**************
+
+Ivy is for quick and easy selection from a list.  When Emacs prompts for
+a string from a list of several possible choices, Ivy springs into
+action to assist in narrowing and picking the right string from a vast
+number of choices.
+
+   Ivy strives for minimalism, simplicity, customizability and
+discoverability.
+
+Minimalism
+..........
+
+     Uncluttered minibuffer is minimalism.  Ivy shows the completion
+     defaults, the number of matches, and 10 candidate matches below the
+     input line.  Customize ‘ivy-height’ to adjust the number of
+     candidate matches displayed in the minibuffer.
+
+Simplicity
+..........
+
+     Simplicity is about Ivy’s behavior in the minibuffer.  It is also
+     about the code interface to extend Ivy’s functionality.  The
+     minibuffer area behaves as close to ‘fundamental-mode’ as possible.
+     ‘SPC’ inserts a space, for example, instead of being bound to the
+     more complex ‘minibuffer-complete-word’.  Ivy’s code uses
+     easy-to-examine global variables; avoids needless complications
+     with branch-introducing custom macros.
+
+Customizability
+...............
+
+     Customizability is about being able to use different methods and
+     interfaces of completion to tailor the selection process.  For
+     example, adding a custom display function that points to a selected
+     candidate with ‘>’, instead of highlighting the selected candidate
+     with the ‘ivy-current-match’ face (see ‘ivy-format-function’).  Or
+     take the customization of actions, say after the candidate function
+     is selected.  ‘RET’ uses ‘counsel-describe-function’ to describe
+     the function, whereas ‘M-o d’ jumps to that function’s definition
+     in the code.  The ‘M-o’ prefix can be uniformly used with
+     characters like ‘d’ to group similar actions.
+
+Discoverability
+...............
+
+     Ivy displays easily discoverable commands through the hydra
+     facility.  ‘C-o’ in the minibuffer displays a hydra menu.  It opens
+     up within an expanded minibuffer area.  Each menu item comes with
+     short documentation strings and highlighted one-key completions.
+     So discovering even seldom used keys is simply a matter of ‘C-o’ in
+     the minibuffer while in the midst of the Ivy interaction.  This
+     discoverability minimizes exiting Ivy interface for documentation
+     look-ups.

+
+2 Installation
+**************
+
+Install Ivy automatically through Emacs’s package manager, or manually
+from Ivy’s development repository.
+
+   Emacs 24.3 is the oldest version to run Ivy.  Emacs 24.4 is the
+oldest version that runs Ivy with fancy faces display.

+
+File: ivy.info,  Node: Installing from Emacs Package Manager,  Next: Installing from the Git repository,  Up: Installation
+
+2.1 Installing from Emacs Package Manager
+=========================================
+
+‘M-x’ ‘package-install’ ‘RET’ ‘ivy’ ‘RET’
+
+   Ivy is installed as part of ‘ivy’ package, which is available from
+two different package archives, GNU ELPA and MELPA. For the latest
+stable version, use the GNU ELPA archives using the above M-x command.
+
+   For current hourly builds, use the MELPA archives.  In MELPA, Ivy is
+split into three packages: ‘ivy’, ‘swiper’ and ‘counsel’; you can simply
+install ‘counsel’ which will bring in the other two as dependencies.
+See the code below for adding MELPA to the list of package archives:
+
+     (require 'package)
+     (add-to-list 'package-archives
+     	     '("melpa" . "http://melpa.org/packages/"))
+
+   After this do ‘M-x’ ‘package-refresh-contents’ ‘RET’, followed by
+‘M-x’ ‘package-install’ ‘RET’ ‘counsel’ ‘RET’.
+
+   For package manager details, see *note (emacs)Packages::.

+
+2.2 Installing from the Git repository
+======================================
+
+Why install from Git?
+.....................
+
+        • No need to wait for MELPA’s hourly builds
+        • Easy to revert to previous versions
+        • Contribute to Ivy’s development; send patches; pull requests
+
+Configuration steps
+...................
+
+     First clone the Swiper repository with:
+
+          cd ~/git && git clone https://github.com/abo-abo/swiper
+          cd swiper && make compile
+
+     Second, add these lines to the Emacs init file:
+
+          (add-to-list 'load-path "~/git/swiper/")
+          (require 'ivy)
+
+     Then, update the code with:
+
+          git pull
+          make
+
+
+File: ivy.info,  Node: Getting started,  Next: Key bindings,  Prev: Installation,  Up: Top
+
+3 Getting started
+*****************
+
+First enable Ivy completion everywhere:
+
+     (ivy-mode 1)
+
+   Note: ‘ivy-mode’ can be toggled on and off with ‘M-x’ ‘ivy-mode’.
+
+* Menu:
+
+* Basic customization::
+
+
+File: ivy.info,  Node: Basic customization,  Up: Getting started
+
+3.1 Basic customization
+=======================
+
+Here are some basic settings particularly useful for new Ivy users:
+
+     (setq ivy-use-virtual-buffers t)
+     (setq ivy-count-format "(%d/%d) ")
+
+   If you want, you can go without any customizations at all.  The above
+settings are the most bang for the buck in terms of customization.  So
+users that typically don’t like customize a lot are advised to look at
+these settings first.
+
+   For more advanced customizations, refer to ‘M-x describe-variable’
+documentation.

+........................................
+
+          (global-set-key (kbd "C-s") 'swiper)

+
+4.2 Minibuffer key bindings
+===========================
+
+Ivy includes several minibuffer bindings, which are defined in the
+‘ivy-minibuffer-map’ keymap variable.  The most frequently used ones are
+described here.
+
+   ‘swiper’ or ‘counsel-M-x’ add more key bindings through the ‘keymap’
+argument to ‘ivy-read’.  These keys, also active in the minibuffer, are
+described under their respective commands.
+
+   A key feature of ‘ivy-minibuffer-map’ is its full editing capability
+where the familiar ‘C-a’, ‘C-f’, ‘M-d’, ‘M-DEL’, ‘M-b’, ‘M-w’, ‘C-k’,
+‘C-y’ key bindings work the same as in ‘fundamental-mode’.

+
+4.2.1 Key bindings for navigation
+---------------------------------
+
+   • ‘C-n’ (‘ivy-next-line’) selects the next candidate
+   • ‘C-p’ (‘ivy-previous-line’) selects the previous candidate
+   • ‘M-<’ (‘ivy-beginning-of-buffer’) selects the first candidate
+   • ‘M->’ (‘ivy-end-of-buffer’) selects the last candidate
+   • ‘C-v’ (‘ivy-scroll-up-command’) scrolls up by ‘ivy-height’ lines
+   • ‘M-v’ (‘ivy-scroll-down-command’) scrolls down by ‘ivy-height’
+     lines
+
+ -- User Option: ivy-wrap
+     Specifies the wrap-around behavior for ‘C-n’ and ‘C-p’.  When
+     ‘ivy-wrap’ is set to ‘t’, ‘ivy-next-line’ and ‘ivy-previous-line’
+     will cycle past the last and the first candidates respectively.
+
+     Warp-around behavior is off by default.
+
+ -- User Option: ivy-height
+     Use this option to adjust the minibuffer height, which also affects
+     scroll size when using ‘C-v’ and ‘M-v’ key bindings.
+
+     ‘ivy-height’ is 10 lines by default.
+
+
+File: ivy.info,  Node: Key bindings for single selection action then exit minibuffer,  Next: Key bindings for multiple selections and actions keep minibuffer open,  Prev: Key bindings for navigation,  Up: Minibuffer key bindings
+
+4.2.2 Key bindings for single selection, action, then exit minibuffer
+---------------------------------------------------------------------
+
+Ivy can offer several actions from which to choose which action to run.
+This "calling an action" operates on the selected candidate.  For
+example, when viewing a list of files, one action could open it for
+editing, one to view it, another to invoke a special function, and so
+on.  Custom actions can be added to this interface.  The precise action
+to call on the selected candidate can be delayed until after the
+narrowing is completed.  No need to exit the interface if unsure which
+action to run.  This delayed flexibility and customization of actions
+extends usability of lists in Emacs.
+
+‘C-m’ or ‘RET’ (‘ivy-done’)
+...........................
+
+     Calls the default action and then exits the minibuffer.
+
+‘M-o’ (‘ivy-dispatching-done’)
+..............................
+
+     Presents valid actions from which to choose.  When only one action
+     is available, there is no difference between ‘M-o’ and ‘C-m’.
+
+‘C-j’ (‘ivy-alt-done’)
+......................
+
+     When completing file names, selects the current directory candidate
+     and starts a new completion session there.  Otherwise, it is the
+     same as ‘ivy-done’.
+
+‘TAB’ (‘ivy-partial-or-done’)
+.............................
+
+     Attempts partial completion, extending current input as much as
+     possible.  ‘TAB TAB’ is the same as ‘C-j’ (‘ivy-alt-done’).
+
+     Example ERT test:
+
+          (should
+           (equal (ivy-with
+          	 '(progn
+          	   (ivy-read "Test: " '("can do" "can't, sorry" "other"))
+          	   ivy-text)
+          	 "c <tab>")
+          	"can"))
+
+‘C-M-j’ (‘ivy-immediate-done’)
+..............................
+
+     Exits with _the current input_ instead of _the current candidate_
+     (like other commands).
+
+     This is useful e.g.  when you call ‘find-file’ to create a new
+     file, but the desired name matches an existing file.  In that case,
+     using ‘C-j’ would select that existing file, which isn’t what you
+     want - use this command instead.
+
+‘C-'’ (‘ivy-avy’)
+.................
+
+     Uses avy to select one of the candidates on the current candidate
+     page.  This can often be faster than multiple ‘C-n’ or ‘C-p’
+     keystrokes followed by ‘C-m’.
+
+
+File: ivy.info,  Node: Key bindings for multiple selections and actions keep minibuffer open,  Next: Key bindings that alter the minibuffer input,  Prev: Key bindings for single selection action then exit minibuffer,  Up: Minibuffer key bindings
+
+4.2.3 Key bindings for multiple selections and actions, keep minibuffer open
+----------------------------------------------------------------------------
+
+For repeatedly applying multiple actions or acting on multiple
+candidates, Ivy does not close the minibuffer between commands.  It
+keeps the minibuffer open for applying subsequent actions.
+
+   Adding an extra meta key to the normal key chord invokes the special
+version of the regular commands that enables applying multiple actions.
+
+‘C-M-m’ (‘ivy-call’)
+....................
+
+     Is the non-exiting version of ‘C-m’ (‘ivy-done’).
+
+     Instead of closing the minibuffer, ‘C-M-m’ allows selecting another
+     candidate or another action.  For example, ‘C-M-m’ on functions
+     list invokes ‘describe-function’.  When combined with ‘C-n’,
+     function descriptions can be invoked quickly in succession.
+
+‘C-M-o’ (‘ivy-dispatching-call’)
+................................
+
+     Is the non-exiting version of ‘M-o’ (‘ivy-dispatching-done’).
+
+     For example, during the ‘counsel-rhythmbox’ completion, press
+     ‘C-M-o e’ to en-queue the selected candidate, followed by ‘C-n C-m’
+     to play the next candidate - the current action reverts to the
+     default one after ‘C-M-o’.
+
+‘C-M-n’ (‘ivy-next-line-and-call’)
+..................................
+
+     Combines ‘C-n’ and ‘C-M-m’.  Applies an action and moves to next
+     line.
+
+     Comes in handy when opening multiple files from
+     ‘counsel-find-file’, ‘counsel-git-grep’, ‘counsel-ag’,
+     ‘counsel-rg’, or ‘counsel-locate’ lists.  Just hold ‘C-M-n’ for
+     rapid-fire default action on each successive element of the list.
+
+‘C-M-p’ (‘ivy-previous-line-and-call’)
+......................................
+
+     Combines ‘C-p’ and ‘C-M-m’.
+
+     Similar to the above except it moves through the list in the other
+     direction.
+
+‘ivy-resume’
+............
+
+     Recalls the state of the completion session just before its last
+     exit.
+
+     Useful after an accidental ‘C-m’ (‘ivy-done’).
+
+
+File: ivy.info,  Node: Key bindings that alter the minibuffer input,  Next: Other key bindings,  Prev: Key bindings for multiple selections and actions keep minibuffer open,  Up: Minibuffer key bindings
+
+4.2.4 Key bindings that alter the minibuffer input
+--------------------------------------------------
+
+‘M-n’ (‘ivy-next-history-element’)
+..................................
+
+     Cycles forward through the Ivy command history.
+
+     Ivy updates an internal history list after each action.  When this
+     history list is empty, ‘M-n’ inserts symbol (or URL) at point into
+     the minibuffer.
+
+‘M-p’ (‘ivy-previous-history-element’)
+......................................
+
+     Cycles forward through the Ivy command history.
+
+‘M-i’ (‘ivy-insert-current’)
+............................
+
+     Inserts the current candidate into the minibuffer.
+
+     Useful for copying and renaming files, for example: ‘M-i’ to insert
+     the original file name string, edit it, and then ‘C-m’ to complete
+     the renaming.
+
+‘M-j’ (‘ivy-yank-word’)
+.......................
+
+     Inserts the sub-word at point into the minibuffer.
+
+     This is similar to ‘C-s C-w’ with ‘isearch’.  Ivy reserves ‘C-w’
+     for ‘kill-region’.  See also ‘ivy-yank-symbol’ and ‘ivy-yank-char’.
+
+‘S-SPC’ (‘ivy-restrict-to-matches’)
+...................................
+
+     Deletes the current input, and resets the candidates list to the
+     currently restricted matches.
+
+     This is how Ivy provides narrowing in successive tiers.
+
+‘C-r’ (‘ivy-reverse-i-search’)
+..............................
+
+     Starts a recursive completion session through the command’s
+     history.
+
+     This works just like ‘C-r’ at the bash command prompt, where the
+     completion candidates are the history items.  Upon completion, the
+     selected candidate string is inserted into the minibuffer.

+     Copies selected candidates to the kill ring.
+
+     Copies the region if the region is active.

+5 Completion Styles
+*******************
+
+Ivy’s completion functions rely on a regex builder - a function that
+transforms a string input to a string regex.  All current candidates
+simply have to match this regex.  Each collection can be assigned its
+own regex builder by customizing ‘ivy-re-builders-alist’.
+
+   The keys of this alist are collection names, and the values are one
+of the following:
+   • ‘ivy--regex’
+   • ‘ivy--regex-plus’
+   • ‘ivy--regex-ignore-order’
+   • ‘ivy--regex-fuzzy’
+   • ‘regexp-quote’
+
+   A catch-all key, ‘t’, applies to all collections that don’t have
+their own key.
+
+   The default is:
+
+     (setq ivy-re-builders-alist
+           '((t . ivy--regex-plus)))
+
+   This example shows a custom regex builder assigned to file name
+completion:
+
+     (setq ivy-re-builders-alist
+           '((read-file-name-internal . ivy--regex-fuzzy)
+     	(t . ivy--regex-plus)))
+
+   Here, ‘read-file-name-internal’ is a function that is passed as the
+second argument to ‘completing-read’ for file name completion.
+
+   The regex builder resolves as follows (in order of priority):
+  1. ‘re-builder’ argument passed to ‘ivy-read’.
+  2. ‘collection’ argument passed to ‘ivy-read’ is a function and has an
+     entry on ‘ivy-re-builders-alist’.
+  3. ‘caller’ argument passed to ‘ivy-read’ has an entry on
+     ‘ivy-re-builders-alist’.
+  4. ‘this-command’ has an entry on ‘ivy-re-builders-alist’.
+  5. ‘t’ has an entry on ‘ivy-re-builders-alist’.
+  6. ‘ivy--regex’.

+
+5.1 ivy–regex-plus
+==================
+
+‘ivy--regex-plus’ is Ivy’s default completion method.
+
+   ‘ivy--regex-plus’ matches by splitting the input by spaces and
+rebuilding it into a regex.
+
+   As the search string is typed in Ivy’s minibuffer, it is transformed
+into valid regex syntax.  If the string is ‘"for example"’, it is
+transformed into
+
+     "\\(for\\).*\\(example\\)"
+
+   which in regex terminology matches ‘"for"’ followed by a wild card
+and then ‘"example"’.  Note how Ivy uses the space character to build
+wild cards.  To match a literal white space, use an extra space.  So to
+match one space type two spaces, to match two spaces type three spaces,
+and so on.
+
+   As Ivy transforms typed characters into regex strings, it provides an
+intuitive feedback through font highlights.
+
+   Ivy supports regexp negation with ‘"!"’.  For example, ‘"define key !
+ivy quit"’ first selects everything matching ‘"define.*key"’, then
+removes everything matching ‘"ivy"’, and finally removes everything
+matching ‘"quit"’.  What remains is the final result set of the negation
+regexp.
+
+   Since Ivy treats minibuffer input as a regexp, the standard regexp
+identifiers work: ‘"^"’, ‘"$"’, ‘"\b"’ or ‘"[a-z]"’.  The exceptions are
+spaces, which translate to ‘".*"’, and ‘"!"’ that signal the beginning
+of a negation group.
+
+
+File: ivy.info,  Node: ivy--regex-ignore-order,  Next: ivy--regex-fuzzy,  Prev: ivy--regex-plus,  Up: Completion Styles
+
+5.2 ivy–regex-ignore-order
+==========================
+
+‘ivy--regex-ignore-order’ ignores the order of regexp tokens when
+searching for matching candidates.  For instance, the input ‘"for
+example"’ will match ‘"example test for"’.
+
+
+File: ivy.info,  Node: ivy--regex-fuzzy,  Prev: ivy--regex-ignore-order,  Up: Completion Styles
+
+5.3 ivy–regex-fuzzy
+===================
+
+‘ivy--regex-fuzzy’ splits each character with a wild card.  Searching
+for ‘"for"’ returns all ‘"f.*o.*r"’ matches, resulting in a large number
+of hits.  Yet some searches need these extra hits.  Ivy sorts such large
+lists using ‘flx’ package’s scoring mechanism, if it’s installed.
+
+   ‘C-o m’ toggles the current regexp builder.

+
+     The confirmation prompt will use this face.
+
+     For example:
+
+          (setq confirm-nonexistent-file-or-buffer t)
+
+     Then call ‘find-file’, enter "eldorado" and press ‘RET’ - the

+
+     When completions have to match available candidates and cannot take

+6.3.1 What are actions?
+-----------------------
+
+An action is a function that is called after you select a candidate
+during completion.  This function takes a single string argument, which
+is the selected candidate.
+
+Window context when calling an action
+.....................................
+
+     Currently, the action is executed in the minibuffer window context.
+     This means e.g.  that if you call ‘insert’ the text will be
+     inserted into the minibuffer.
+
+     If you want to execute the action in the initial window from which
+     the completion started, use the ‘with-ivy-window’ wrapper macro.
+
+          (defun ivy-insert-action (x)
+            (with-ivy-window
+              (insert x)))

+
+6.3.2 How can different actions be called?
+------------------------------------------
+
+   • ‘C-m’ (‘ivy-done’) calls the current action.
+   • ‘M-o’ (‘ivy-dispatching-done’) presents available actions for
+     selection, calls it after selection, and then exits.
+   • ‘C-M-o’ (‘ivy-dispatching-call’) presents available actions for
+     selection, calls it after selection, and then does not exit.
+
+
+File: ivy.info,  Node: How to modify the actions list?,  Next: Example - add two actions to each command,  Prev: How can different actions be called?,  Up: Actions
+
+6.3.3 How to modify the actions list?
+-------------------------------------
+
+Currently, you can append any amount of your own actions to the default
+list of actions.  This can be done either for a specific command, or for
+all commands at once.
+
+   Usually, the command has only one default action.  The convention is
+to use single letters when selecting a command, and the letter ‘o’ is
+designated for the default command.  This way, ‘M-o o’ should be always
+equivalent to ‘C-m’.
+
+
+File: ivy.info,  Node: Example - add two actions to each command,  Next: Example - define a new command with several actions,  Prev: How to modify the actions list?,  Up: Actions
+
+6.3.4 Example - add two actions to each command
+-----------------------------------------------
+
+The first action inserts the current candidate into the Ivy window - the
+window from which ‘ivy-read’ was called.
+
+   The second action copies the current candidate to the kill ring.
+
+     (defun ivy-yank-action (x)
+       (kill-new x))
+
+     (defun ivy-copy-to-buffer-action (x)
+       (with-ivy-window
+         (insert x)))
+
+     (ivy-set-actions
+      t
+      '(("i" ivy-copy-to-buffer-action "insert")
+        ("y" ivy-yank-action "yank")))
+
+   Then in any completion session, ‘M-o y’ invokes ‘ivy-yank-action’,
+and ‘M-o i’ invokes ‘ivy-copy-to-buffer-action’.

+7.1 File Name Completion
+========================
+
+Since file name completion is ubiquitous, Ivy provides extra bindings
+that work here:
+
+‘C-j’ (‘ivy-alt-done’)
+......................
+
+     On a directory, restarts completion from that directory.
+
+     On a file or ‘./’, exit completion with the selected candidate.
+
+‘DEL’ (‘ivy-backward-delete-char’)
+..................................

+     Restart the completion in the parent directory if current input is
+     empty.
+
+‘//’ (‘self-insert-command’)
+............................
+
+     Switch to the root directory.
+
+‘~’ (‘self-insert-command’)
+...........................
+
+     Switch to the home directory.
+
+‘/’ (‘self-insert-command’)
+...........................
+
+     If the current input matches an existing directory name exactly,
+     switch the completion to that directory.
+
+‘M-r’ (‘ivy-toggle-regexp-quote’)
+.................................
+
+     Toggle between input as regexp or not.
+
+     Switch to matching literally since file names include ‘.’, which is
+     for matching any char in regexp mode.
+ -- User Option: ivy-extra-directories
+     Decide if you want to see ‘../’ and ‘./’ during file name
+     completion.
+
+     Reason to remove: ‘../’ is the same as ‘DEL’.
+
+     Reason not to remove: navigate anywhere with only ‘C-n’, ‘C-p’ and
+     ‘C-j’.
+
+     Likewise, ‘./’ can be removed.
+
+History
+.......
+
+     File history works the same with ‘M-p’, ‘M-n’, and ‘C-r’, but uses
+     a custom code for file name completion that cycles through files
+     previously opened.  It also works with TRAMP files.

+* Menu:

+* Using TRAMP::
+
+
+File: ivy.info,  Node: Using TRAMP,  Up: File Name Completion
+
+7.1.1 Using TRAMP
+-----------------
+
+From any directory, with the empty input, inputting ‘/ssh:’ and pressing
+‘C-j’ (or ‘RET’, which is the same thing) completes for host and user
+names.
+
+   For ‘/ssh:user@’ input, completes the domain name.
+
+   ‘C-i’ works in a similar way to the default completion.
+
+   You can also get sudo access for the current directory by inputting
+‘/sudo::’ ‘RET’.  Using ‘/sudo:’ (i.e.  single colon instead of double)
+will result in a completion session for the desired user.
+
+   Multi-hopping is possible, although a bit complex.
+
+Example : connect to a remote host ‘cloud’ and open a file with ‘sudo’ there
+............................................................................
+
+        • ‘C-x C-f’ ‘/ssh:cloud|sudo:root:/’.

+====================
+
+The main advantages of ‘counsel-’ functions over their basic equivalents
+in ‘ivy-mode’ are:
+
+  1. Multi-actions and non-exiting actions work.
+  2. ‘ivy-resume’ can resume the last completion session.
+  3. Customize ‘ivy-set-actions’, ‘ivy-re-builders-alist’.
+  4. Customize individual keymaps, such as ‘counsel-describe-map’,
+     ‘counsel-git-grep-map’, or ‘counsel-find-file-map’, instead of

+8.1 Required arguments for ‘ivy-read’
+=====================================
+
+‘prompt’
+........
+
+     A format string normally ending in a colon and a space.
+
+     ‘%d’ anywhere in the string is replaced by the current number of
+     matching candidates.  To use a literal ‘%’ character, escape it as
+     ‘%%’.  See also ‘ivy-count-format’.
+
+‘collection’
+............
+
+     Either a list of strings, a function, an alist or a hash table.
+
+     If a function, then it has to be compatible with ‘all-completions’.
+
+
+File: ivy.info,  Node: Optional arguments for ivy-read,  Next: Example - counsel-describe-function,  Prev: Required arguments for ivy-read,  Up: API
+
+8.2 Optional arguments for ‘ivy-read’
+=====================================
+
+‘predicate’
+...........
+
+     Is a function to filter the initial collection.  It has to be
+     compatible with ‘all-completions’.  Tip: most of the time, it’s
+     simpler to just apply this filter to the ‘collection’ argument
+     itself, e.g.  ‘(cl-remove-if-not predicate collection)’.
+
+‘require-match’
+...............
+
+     When set to a non-nil value, input must match one of the
+     candidates.  Custom input is not accepted.
+
+‘initial-input’
+...............
+
+     This string argument is included for compatibility with
+     ‘completing-read’, which inserts it into the minibuffer.
+
+     It’s recommended to use the ‘preselect’ argument instead of this.
+
+‘history’
+.........
+
+     Name of the symbol to store history.  See ‘completing-read’.
+
+‘preselect’
+...........
+
+     When set to a string value, select the first candidate matching
+     this value.
+
+     When set to an integer value, select the candidate with that index
+     value.
+
+     Every time the input becomes empty, the item corresponding to to
+     ‘preselect’ is selected.
+
+‘keymap’
+........
+
+     A keymap to be composed with ‘ivy-minibuffer-map’.  This keymap has
+     priority over ‘ivy-minibuffer-map’ and can be modified at any later
+     stage.
+
+‘update-fn’
+...........
+
+     Is the function called each time the current candidate changes.
+     This function takes no arguments and is called in the minibuffer’s
+     ‘post-command-hook’.  See ‘swiper’ for an example usage.
+
+‘sort’
+......
+
+     When non-nil, use ‘ivy-sort-functions-alist’ to sort the collection
+     as long as the collection is not larger than ‘ivy-sort-max-size’.
+
+‘action’
+........
+
+     Is the function to call after selection.  It takes a string
+     argument.
+
+‘unwind’
+........
+
+     Is the function to call before exiting completion.  It takes no
+     arguments.  This function is called even if the completion is
+     interrupted with ‘C-g’.  See ‘swiper’ for an example usage.
+
+‘re-builder’
+............
+
+     Is a function that takes a string and returns a valid regex.  See
+     ‘Completion Styles’ for details.
+
+‘matcher’
+.........
+
+     Is a function that takes a regex string and a list of strings and
+     returns a list of strings matching the regex.  Any ordinary Emacs
+     matching function will suffice, yet finely tuned matching functions
+     can be used.  See ‘counsel-find-file’ for an example usage.
+
+‘dynamic-collection’
+....................
+
+     When non-nil, ‘collection’ will be used to dynamically generate the
+     candidates each time the input changes, instead of being used once
+     statically with ‘all-completions’ to generate a list of strings.
+     See ‘counsel-locate’ for an example usage.
+
+‘caller’
+........
+
+     Is a symbol that uniquely identifies the function that called
+     ‘ivy-read’, which may be useful for further customizations.
+
+
+File: ivy.info,  Node: Example - counsel-describe-function,  Next: Example - counsel-locate,  Prev: Optional arguments for ivy-read,  Up: API
+
+8.3 Example - ‘counsel-describe-function’
+=========================================
+
+This is a typical example of a function with a non-async collection,
+which is a collection where all the strings in the collection are known
+prior to any input from the user.
+
+   Only the first two arguments (along with ‘action’) are essential -
+the rest of the arguments are for fine-tuning, and could be omitted.
+
+   The ‘action’ argument could also be omitted - but then ‘ivy-read’
+would do nothing except returning the string result, which you could
+later use yourself.  However, it’s recommended that you use the ‘action’
+argument.
+
+     (defun counsel-describe-function ()
+       "Forward to `describe-function'."
+       (interactive)
+       (ivy-read "Describe function: "
+     	    (let (cands)
+     	      (mapatoms
+     	       (lambda (x)
+     		 (when (fboundp x)
+     		   (push (symbol-name x) cands))))
+     	      cands)
+     	    :keymap counsel-describe-map
+     	    :preselect (counsel-symbol-at-point)
+     	    :history 'counsel-describe-symbol-history
+     	    :require-match t
+     	    :sort t
+     	    :action (lambda (x)
+     		      (describe-function
+     		       (intern x)))
+     	    :caller 'counsel-describe-function))
+
+   Here are the interesting features of the above function, in the order
+that they appear:
+
+   • The ‘prompt’ argument is a simple string ending in ": ".
+   • The ‘collection’ argument evaluates to a (large) list of strings.
+   • The ‘keymap’ argument is for a custom keymap to supplement
+     ‘ivy-minibuffer-map’.
+   • The ‘preselect’ is provided by ‘counsel-symbol-at-point’, which
+     returns a symbol near the point.  Ivy then selects the first
+     candidate from the collection that matches this symbol.  To select
+     this pre-selected candidate, a ‘RET’ will suffice.  No further user
+     input is necessary.
+   • The ‘history’ argument is for keeping the history of this command
+     separate from the common history in ‘ivy-history’.
+   • The ‘require-match’ is set to ‘t’ since it doesn’t make sense to
+     call ‘describe-function’ on an un-interned symbol.
+   • The ‘sort’ argument is set to ‘t’ so choosing between similar
+     candidates becomes easier.  Sometimes, the collection size will
+     exceed ‘ivy-sort-max-size’, which is 30000 by default.  In that
+     case the sorting will not happen to avoid delays.
+
+     Adjust this variable to choose between sorting time and completion
+     start-up time.
+   • The ‘action’ argument calls ‘describe-function’ on the interned
+     selected candidate.
+   • The ‘caller’ argument identifies this completion session.  This is
+     important, since with the collection being a list of strings and
+     not a function name, the only other way for ‘ivy-read’ to identify
+     "who’s calling" and to apply the appropriate customizations is to
+     examine ‘this-command’.  But ‘this-command’ would be modified if
+     another command called ‘counsel-describe-function’.

+
+8.4 Example - ‘counsel-locate’
+==============================
+
+This is a typical example of a function with an async collection.  Since
+the collection function cannot pre-compute all the locatable files in
+memory within reasonable limits (time or memory), it relies on user
+input to filter the universe of possible candidates to a manageable size
+while also continuing to search asynchronously for possible candidates.
+Both the filtering and searching continues with each character change of
+the input with rapid updates to the collection presented without idle
+waiting times.  This live update will continue as long as there are
+likely candidates.  Eventually updates to the minibuffer will stop after
+user input, filtering, and searching have exhausted looking for possible
+candidates.
+
+   Async collections suit long-running shell commands, such as ‘locate’.
+With each new input, a new process starts while the old process is
+killed.  The collection is refreshed anew with each new process.
+Meanwhile the user can provide more input characters (for further
+narrowing) or select a candidate from the visible collection.
+
+     (defun counsel-locate-function (str)
+       (or
+        (counsel-more-chars)
+        (progn
+          (counsel--async-command
+           (format "locate %s '%s'"
+     	      (mapconcat #'identity counsel-locate-options " ")
+     	      (counsel-unquote-regex-parens
+     	       (ivy--regex str))))
+          '("" "working..."))))
+
+     ;;;###autoload
+     (defun counsel-locate (&optional initial-input)
+       "Call the \"locate\" shell command.
+     INITIAL-INPUT can be given as the initial minibuffer input."
+       (interactive)
+       (ivy-read "Locate: " #'counsel-locate-function
+     	    :initial-input initial-input
+     	    :dynamic-collection t
+     	    :history 'counsel-locate-history
+     	    :action (lambda (file)
+     		      (with-ivy-window
+     			(when file
+     			  (find-file file))))
+     	    :unwind #'counsel-delete-process
+     	    :caller 'counsel-locate))
+
+   Here are the interesting features of the above functions, in the
+order that they appear:
+
+   • ‘counsel-locate-function’ takes a string argument and returns a
+     list of strings.  Note that it’s not compatible with
+     ‘all-completions’, but since we’re not using that here, might as
+     well use one argument instead of three.
+   • ‘counsel-more-chars’ is a simple function that returns e.g.  ‘'("2
+     chars more")’ asking the user for more input.
+   • ‘counsel--async-command’ is a very easy API simplification that
+     takes a single string argument suitable for
+     ‘shell-command-to-string’.  So you could prototype your function as
+     non-async using ‘shell-command-to-string’ and ‘split-string’ to
+     produce a collection, then decide that you want async and simply
+     swap in ‘counsel--async-command’.
+   • ‘counsel-locate’ is an interactive function with an optional
+     ‘initial-input’.
+   • ‘#'counsel-locate-function’ is passed as the ‘collection’ argument.
+   • ‘dynamic-collection’ is set to t, since this is an async
+     collection.
+   • ‘action’ argument uses ‘with-ivy-window’ wrapper, since we want to
+     open the selected file in the same window from which
+     ‘counsel-locate’ was called.
+   • ‘unwind’ argument is set to ‘#'counsel-delete-process’: when we
+     press ‘C-g’ we want to kill the running process created by
+     ‘counsel--async-command’.
+   • ‘caller’ argument identifies this command for easier customization.

+8.5 Example - ‘ivy-read-with-extra-properties’
+==============================================
+
+This is another example to show how to associate additional values to
+each displayed strings.
+
+     (defun find-candidates-function (str pred _)
+       (let ((props '(1 2))
+     	(strs '("foo" "foo2")))
+         (cl-mapcar (lambda (s p) (propertize s 'property p))
+     	       strs
+     	       props)))
+
+     (defun find-candidates ()
+       (interactive)
+       (ivy-read "Find symbols: "
+     	    #'find-candidates-function
+     	    :action (lambda (x)
+     		      (message "Value: %s" (get-text-property 0 'property x)
+     		       ))))
+
+   Here are the interesting features of the above function:
+
+   • ‘find-candidates-function’ builds up a list of strings and
+     associates "foo" with the value 1 and "foo2" with 2.
+   • ‘find-candidates’ is an interactive function.
+   • ‘#'find-candidates’ is passed as the ‘collection’ argument.
+   • ‘action’ gets passed the selected string with the associated value.
+     It then retrieves that value and displays it.
