# readline

## NAME



           readline - get a line from a user with editing
    


## SYNOPSIS



           **#include <stdio.h>**
           **#include <readline/readline.h>**
           **#include <readline/history.h>**
    
           _char *_
           **readline**(_const char *prompt_);
    


## DESCRIPTION



           **readline** reads a line from the terminal and return it, using
           **prompt** as a prompt.  If **prompt** is **NULL** or the empty string,
           **readline** does not issue a prompt.  The line returned is allocated
           with malloc(3); the caller must free it when finished.  The line
           returned has the final newline removed, so only the text of the
           line remains.  Since it's possible to enter characters into the
           line while quoting them to disable any **readline** editing function
           they might normally have, this line may include embedded newlines
           and other special characters.
    
           **readline** offers editing capabilities while the user is entering
           the line.  By default, the line editing commands are similar to
           those of emacs.  A vi-style line editing interface is also
           available.
    
           This manual page describes only the most basic use of **readline**.
           Much more functionality is available; see _The GNU Readline Library_
           and _The GNU History Library_ for additional information.
    


## RETURN VALUE



           **readline** returns the text of the line read.  A blank line returns
           the empty string.  If **EOF** is encountered while reading a line, and
           the line is empty, **readline** returns **NULL**.  If an **EOF** is read with
           a non-empty line, it is treated as a newline.
    


## NOTATION



           This section uses Emacs-style editing concepts and uses its
           notation for keystrokes.  Control keys are denoted by C-_key_ , e.g.,
           C-n means Control-N.  Similarly, _meta_ keys are denoted by M-_key_ ,
           so M-x means Meta-X.  The Meta key is often labeled “Alt” or
           “Option”.
    
           On keyboards without a _Meta_ key, M-_x_ means ESC _x_ , i.e., press and
           release the Escape key, then press and release the _x_ key, in
           sequence.  This makes ESC the _meta prefix_.  The combination M-C-_x_
           means ESC Control-_x_ : press and release the Escape key, then press
           and hold the Control key while pressing the _x_ key, then release
           both.
    
           On some keyboards, the Meta key modifier produces characters with
           the eighth bit (0200) set.  You can use the **enable-meta-key**
           variable to control whether or not it does this, if the keyboard
           allows it.  On many others, the terminal or terminal emulator
           converts the metafied key to a key sequence beginning with ESC as
           described in the preceding paragraph.
    
           If your _Meta_ key produces a key sequence with the ESC meta prefix,
           you can make M-_key_ key bindings you specify (see **Readline Key**
           **Bindings** below) do the same thing by setting the **force-meta-prefix**
           variable.
    
           **Readline** commands may be given numeric _arguments_ , which normally
           act as a repeat count.  Sometimes, however, it is the sign of the
           argument that is significant.  Passing a negative argument to a
           command that acts in the forward direction (e.g., **kill-line**) makes
           that command act in a backward direction.  Commands whose behavior
           with arguments deviates from this are noted below.
    
           The _point_ is the current cursor position, and _mark_ refers to a
           saved cursor position.  The text between the point and mark is
           referred to as the _region_.
    
           When a command is described as _killing_ text, the text deleted is
           saved for possible future retrieval (_yanking_).  The killed text is
           saved in a _kill ring_.  Consecutive kills accumulate the deleted
           text into one unit, which can be yanked all at once.  Commands
           which do not kill text separate the chunks of text on the kill
           ring.
    


## INITIALIZATION FILE



           **Readline** is customized by putting commands in an initialization
           file (the _inputrc_ file).  The name of this file is taken from the
           value of the **INPUTRC** environment variable.  If that variable is
           unset, the default is _~/.inputrc_.  If that file  does not exist or
           cannot be read, **readline** looks for _/etc/inputrc_.  When a program
           that uses the **readline** library starts up, **readline** reads the
           initialization file and sets the key bindings and variables found
           there, before reading any user input.
    
           There are only a few basic constructs allowed in the inputrc file.
           Blank lines are ignored.  Lines beginning with a **#** are comments.
           Lines beginning with a **$** indicate conditional constructs.  Other
           lines denote key bindings and variable settings.
    
           The default key-bindings in this document may be changed using key
           binding commands in the _inputrc_ file.  Programs that use this
           library may add their own commands and bindings.
    
           For example, placing
    
                  M-Control-u: universal-argument
           or
                  C-Meta-u: universal-argument
    
           into the _inputrc_ would make M-C-u execute the **readline** command
           _universal-argument_.
    
           Key bindings may contain the following symbolic character names:
           _DEL_ , _ESC_ , _ESCAPE_ , _LFD_ , _NEWLINE_ , _RET_ , _RETURN_ , _RUBOUT_ (a destructive
           backspace), _SPACE_ , _SPC_ , and _TAB_.
    
           In addition to command names, **readline** allows keys to be bound to
           a string that is inserted when the key is pressed (a _macro_).  The
           difference between a macro and a command is that a macro is
           enclosed in single or double quotes.
    
       **Key Bindings**
           The syntax for controlling key bindings in the _inputrc_ file is
           simple.  All that is required is the name of the command or the
           text of a macro and a key sequence to which it should be bound.
           The key sequence may be specified in one of two ways: as a
           symbolic key name, possibly with _Meta-_ or _Control-_ prefixes, or as
           a key sequence composed of one or more characters enclosed in
           double quotes.  The key sequence and name are separated by a
           colon.  There can be no whitespace between the name and the colon.
    
           When using the form **keyname** :_function-name_ or _macro_ , _keyname_ is the
           name of a key spelled out in English.  For example:
    
                  Control-u: universal-argument
                  Meta-Rubout: backward-kill-word
                  Control-o: "> output"
    
           In the above example, _C-u_ is bound to the function
           **universal-argument** , _M-DEL_ is bound to the function
           **backward-kill-word** , and _C-o_ is bound to run the macro expressed on
           the right hand side (that is, to insert the text “> output” into
           the line).
    
           In the second form, **"keyseq"** :_function-name_ or _macro_ , **keyseq**
           differs from **keyname** above in that strings denoting an entire key
           sequence may be specified by placing the sequence within double
           quotes.  Some GNU Emacs style key escapes can be used, as in the
           following example, but none of the symbolic character names are
           recognized.
    
                  "\C-u": universal-argument
                  "\C-x\C-r": re-read-init-file
                  "\e[11~": "Function Key 1"
    
           In this example, _C-u_ is again bound to the function
           **universal-argument**.  _C-x C-r_ is bound to the function
           **re-read-init-file** , and _ESC [ 1 1 ~_ is bound to insert the text
           “Function Key 1”.
    
           The full set of GNU Emacs style escape sequences available when
           specifying key sequences is
                  **\C-** A control prefix.
                  **\M-** Adding the meta prefix or converting the following
                         character to a meta character, as described below
                         under **force-meta-prefix**.
                  **\e** An escape character.
                  **\\** Backslash.
                  **\"** Literal ", a double quote.
                  **\'** Literal ', a single quote.
    
           In addition to the GNU Emacs style escape sequences, a second set
           of backslash escapes is available:
                  **\a** alert (bell)
                  **\b** backspace
                  **\d** delete
                  **\f** form feed
                  **\n** newline
                  **\r** carriage return
                  **\t** horizontal tab
                  **\v** vertical tab
                  **\**_nnn_   The eight-bit character whose value is the octal
                         value _nnn_ (one to three digits).
                  **\x** _HH_   The eight-bit character whose value is the
                         hexadecimal value _HH_ (one or two hex digits).
    
           When entering the text of a macro, single or double quotes must be
           used to indicate a macro definition.  Unquoted text is assumed to
           be a function name.  The backslash escapes described above are
           expanded in the macro body.  Backslash quotes any other character
           in the macro text, including " and '.
    
           **Bash** will display or modify the current **readline** key bindings with
           the **bind** builtin command.  The **-o emacs** or **-o vi** options to the
           **set** builtin change the editing mode during interactive use.  Other
           programs using this library provide similar mechanisms.  A user
           may always edit the _inputrc_ file and have **readline** re-read it if a
           program does not provide any other means to incorporate new
           bindings.
    
       **Variables**
           **Readline** has variables that can be used to further customize its
           behavior.  A variable may be set in the _inputrc_ file with a
           statement of the form
    
                  **set** _variable-name value_
    
           Except where noted, **readline** variables can take the values **On** or
           **Off**(without regard to case).  Unrecognized variable names are
           ignored.  When **readline** reads a variable value, empty or null
           values, “on” (case-insensitive), and “1” are equivalent to **On**.
           All other values are equivalent to **Off**.
    
           The variables and their default values are:
    
           **active-region-start-color**
                  A string variable that controls the text color and
                  background when displaying the text in the active region
                  (see the description of **enable-active-region** below).  This
                  string must not take up any physical character positions on
                  the display, so it should consist only of terminal escape
                  sequences.  It is output to the terminal before displaying
                  the text in the active region.  This variable is reset to
                  the default value whenever the terminal type changes.  The
                  default value is the string that puts the terminal in
                  standout mode, as obtained from the terminal's terminfo
                  description.  A sample value might be “\e[01;33m”.
           **active-region-end-color**
                  A string variable that “undoes” the effects of
                  **active-region-start-color** and restores “normal” terminal
                  display appearance after displaying text in the active
                  region.  This string must not take up any physical
                  character positions on the display, so it should consist
                  only of terminal escape sequences.  It is output to the
                  terminal after displaying the text in the active region.
                  This variable is reset to the default value whenever the
                  terminal type changes.  The default value is the string
                  that restores the terminal from standout mode, as obtained
                  from the terminal's terminfo description.  A sample value
                  might be “\e[0m”.
           **bell-style (audible)**
                  Controls what happens when **readline** wants to ring the
                  terminal bell.  If set to **none** , **readline** never rings the
                  bell.  If set to **visible** , **readline** uses a visible bell if
                  one is available.  If set to **audible** , **readline** attempts to
                  ring the terminal's bell.
           **bind-tty-special-chars (On)**
                  If set to **On** , **readline** attempts to bind the control
                  characters that are treated specially by the kernel's
                  terminal driver to their **readline** equivalents.  These
                  override the default **readline** bindings described here.
                  Type “stty -a” at a **bash** prompt to see your current
                  terminal settings, including the special control characters
                  (usually **cchars**).
           **blink-matching-paren (Off)**
                  If set to **On** , **readline** attempts to briefly move the cursor
                  to an opening parenthesis when a closing parenthesis is
                  inserted.
           **colored-completion-prefix (Off)**
                  If set to **On** , when listing completions, **readline** displays
                  the common prefix of the set of possible completions using
                  a different color.  The color definitions are taken from
                  the value of the **LS_COLORS** environment variable.  If there
                  is a color definition in **$LS_COLORS** for the custom suffix
                  “readline-colored-completion-prefix”, **readline** uses this
                  color for the common prefix instead of its default.
           **colored-stats (Off)**
                  If set to **On** , **readline** displays possible completions using
                  different colors to indicate their file type.  The color
                  definitions are taken from the value of the **LS_COLORS**
                  environment variable.
           **comment-begin (** “**#** ”**)**
                  The string that the **readline insert-comment** command
                  inserts.  This command is bound to **M-#** in emacs mode and to
                  **#** in vi command mode.
           **completion-display-width (-1)**
                  The number of screen columns used to display possible
                  matches when performing completion.  The value is ignored
                  if it is less than 0 or greater than the terminal screen
                  width.  A value of 0 causes matches to be displayed one per
                  line.  The default value is -1.
           **completion-ignore-case (Off)**
                  If set to **On** , **readline** performs filename matching and
                  completion in a case-insensitive fashion.
           **completion-map-case (Off)**
                  If set to **On** , and **completion-ignore-case** is enabled,
                  **readline** treats hyphens (_-_) and underscores (___) as
                  equivalent when performing case-insensitive filename
                  matching and completion.
           **completion-prefix-display-length**(0)
                  The maximum length in characters of the common prefix of a
                  list of possible completions that is displayed without
                  modification.  When set to a value greater than zero,
                  **readline** replaces common prefixes longer than this value
                  with an ellipsis when displaying possible completions.  If
                  a completion begins with a period, and **eadline** is
                  completing filenames, it uses three underscores instead of
                  an ellipsis.
           **completion-query-items (100)**
                  This determines when the user is queried about viewing the
                  number of possible completions generated by the
                  **possible-completions** command.  It may be set to any integer
                  value greater than or equal to zero.  If the number of
                  possible completions is greater than or equal to the value
                  of this variable, **readline** asks whether or not the user
                  wishes to view them; otherwise **readline** simply lists them
                  on the terminal.  A zero value means **readline** should never
                  ask; negative values are treated as zero.
           **convert-meta (On)**
                  If set to **On** , **readline** converts characters it reads that
                  have the eighth bit set to an ASCII key sequence by
                  clearing the eighth bit and prefixing it with an escape
                  character (converting the character to have the meta
                  prefix).  The default is _On_ , but **readline** sets it to _Off_ if
                  the locale contains characters whose encodings may include
                  bytes with the eighth bit set.  This variable is dependent
                  on the **LC_CTYPE** locale category, and may change if the
                  locale changes.  This variable also affects key bindings;
                  see the description of **force-meta-prefix** below.
           **disable-completion (Off)**
                  If set to **On** , **readline** inhibits word completion.
                  Completion characters are inserted into the line as if they
                  had been mapped to **self-insert**.
           **echo-control-characters (On)**
                  When set to **On** , on operating systems that indicate they
                  support it, **readline** echoes a character corresponding to a
                  signal generated from the keyboard.
           **editing-mode (emacs)**
                  Controls whether **readline** uses a set of key bindings
                  similar to _Emacs_ or _vi_.  **editing-mode** can be set to either
                  **emacs** or **vi**.
           **emacs-mode-string (@)**
                  If the _show-mode-in-prompt_ variable is enabled, this string
                  is displayed immediately before the last line of the
                  primary prompt when emacs editing mode is active.  The
                  value is expanded like a key binding, so the standard set
                  of meta- and control- prefixes and backslash escape
                  sequences is available.  The \1 and \2 escapes begin and
                  end sequences of non-printing characters, which can be used
                  to embed a terminal control sequence into the mode string.
           **enable-active-region (On)**
                  When this variable is set to _On_ , **readline** allows certain
                  commands to designate the region as _active_.  When the
                  region is active, **readline** highlights the text in the
                  region using the value of the **active-region-start-color**
                  variable, which defaults to the string that enables the
                  terminal's standout mode.  The active region shows the text
                  inserted by bracketed-paste and any matching text found by
                  incremental and non-incremental history searches.
           **enable-bracketed-paste (On)**
                  When set to **On** , **readline** configures the terminal to insert
                  each paste into the editing buffer as a single string of
                  characters, instead of treating each character as if it had
                  been read from the keyboard.  This is called
                  _bracketed-paste mode_ ; it prevents **readline** from executing
                  any editing commands bound to key sequences appearing in
                  the pasted text.
           **enable-keypad (Off)**
                  When set to **On** , **readline** tries to enable the application
                  keypad when it is called.  Some systems need this to enable
                  the arrow keys.
           **enable-meta-key (On)**
                  When set to **On** , **readline** tries to enable any meta modifier
                  key the terminal claims to support.  On many terminals, the
                  Meta key is used to send eight-bit characters; this
                  variable checks for the terminal capability that indicates
                  the terminal can enable and disable a mode that sets the
                  eighth bit of a character (0200) if the Meta key is held
                  down when the character is typed (a meta character).
           **expand-tilde (Off)**
                  If set to **On** , **readline** performs tilde expansion when it
                  attempts word completion.
           **force-meta-prefix (Off)**
                  If set to **On** , **readline** modifies its behavior when binding
                  key sequences containing \M- or Meta- (see **Key Bindings**
                  above) by converting a key sequence of the form \M-_C_ or
                  Meta-_C_ to the two-character sequence **ESC** _C_ (adding the meta
                  prefix).  If **force-meta-prefix** is set to **Off**(the default),
                  **readline** uses the value of the **convert-meta** variable to
                  determine whether to perform this conversion: if
                  **convert-meta** is **On** , **readline** performs the conversion
                  described above; if it is **Off** , **readline** converts _C_ to a
                  meta character by setting the eighth bit (0200).
           **history-preserve-point (Off)**
                  If set to **On** , the history code attempts to place point at
                  the same location on each history line retrieved with
                  **previous-history** or **next-history**.
           **history-size (unset)**
                  Set the maximum number of history entries saved in the
                  history list.  If set to zero, any existing history entries
                  are deleted and no new entries are saved.  If set to a
                  value less than zero, the number of history entries is not
                  limited.  By default, the number of history entries is not
                  limited.  Setting _history-size_ to a non-numeric value will
                  set the maximum number of history entries to 500.
           **horizontal-scroll-mode (Off)**
                  Setting this variable to **On** makes **readline** use a single
                  line for display, scrolling the input horizontally on a
                  single screen line when it becomes longer than the screen
                  width rather than wrapping to a new line.  This setting is
                  automatically enabled for terminals of height 1.
           **input-meta (Off)**
                  If set to **On** , **readline** enables eight-bit input (that is, it
                  does not clear the eighth bit in the characters it reads),
                  regardless of what the terminal claims it can support.  The
                  default is _Off_ , but **readline** sets it to _On_ if the locale
                  contains characters whose encodings may include bytes with
                  the eighth bit set.  This variable is dependent on the
                  **LC_CTYPE** locale category, and its value may change if the
                  locale changes.  The name **meta-flag** is a synonym for
                  **input-meta**.
           **isearch-terminators (** “**C-[C-j** ”**)**
                  The string of characters that should terminate an
                  incremental search without subsequently executing the
                  character as a command.  If this variable has not been
                  given a value, the characters _ESC_ and **C-j** terminate an
                  incremental search.
           **keymap (emacs)**
                  Set the current **readline** keymap.  The set of valid keymap
                  names is _emacs, emacs-standard, emacs-meta, emacs-ctlx, vi,_
                  _vi-command_ , and _vi-insert_.  _vi_ is equivalent to _vi-command_ ;
                  _emacs_ is equivalent to _emacs-standard_.  The default value
                  is _emacs_ ; the value of **editing-mode** also affects the
                  default keymap.
           **keyseq-timeout (500)**
                  Specifies the duration **readline** will wait for a character
                  when reading an ambiguous key sequence (one that can form a
                  complete key sequence using the input read so far, or can
                  take additional input to complete a longer key sequence).
                  If **readline** does not receive any input within the timeout,
                  it uses the shorter but complete key sequence.  The value
                  is specified in milliseconds, so a value of 1000 means that
                  **readline** will wait one second for additional input.  If
                  this variable is set to a value less than or equal to zero,
                  or to a non-numeric value, **readline** waits until another key
                  is pressed to decide which key sequence to complete.
           **mark-directories (On)**
                  If set to **On** , completed directory names have a slash
                  appended.
           **mark-modified-lines (Off)**
                  If set to **On** , **readline** displays history lines that have
                  been modified with a preceding asterisk (*****).
           **mark-symlinked-directories (Off)**
                  If set to **On** , completed names which are symbolic links to
                  directories have a slash appended, subject to the value of
                  **mark-directories**.
           **match-hidden-files (On)**
                  This variable, when set to **On** , forces **readline** to match
                  files whose names begin with a “.”  (hidden files) when
                  performing filename completion.  If set to **Off** , the user
                  must include the leading “.”  in the filename to be
                  completed.
           **menu-complete-display-prefix (Off)**
                  If set to **On** , menu completion displays the common prefix of
                  the list of possible completions (which may be empty)
                  before cycling through the list.
           **output-meta (Off)**
                  If set to **On** , **readline** displays characters with the eighth
                  bit set directly rather than as a meta-prefixed escape
                  sequence.  The default is _Off_ , but **readline** sets it to _On_
                  if the locale contains characters whose encodings may
                  include bytes with the eighth bit set.  This variable is
                  dependent on the **LC_CTYPE** locale category, and its value
                  may change if the locale changes.
           **page-completions (On)**
                  If set to **On** , **readline** uses an internal pager resembling
                  more(1) to display a screenful of possible completions at a
                  time.
           **prefer-visible-bell**
                  See **bell-style**.
           **print-completions-horizontally (Off)**
                  If set to **On** , **readline** displays completions with matches
                  sorted horizontally in alphabetical order, rather than down
                  the screen.
           **revert-all-at-newline (Off)**
                  If set to **On** , **readline** will undo all changes to history
                  lines before returning when executing **accept-line**.  By
                  default, history lines may be modified and retain
                  individual undo lists across calls to **readline()**.
           **search-ignore-case (Off)**
                  If set to **On** , **readline** performs incremental and non-
                  incremental history list searches in a case-insensitive
                  fashion.
           **show-all-if-ambiguous (Off)**
                  This alters the default behavior of the completion
                  functions.  If set to **On** , words which have more than one
                  possible completion cause the matches to be listed
                  immediately instead of ringing the bell.
           **show-all-if-unmodified (Off)**
                  This alters the default behavior of the completion
                  functions in a fashion similar to **show-all-if-ambiguous**.
                  If set to **On** , words which have more than one possible
                  completion without any possible partial completion (the
                  possible completions don't share a common prefix) cause the
                  matches to be listed immediately instead of ringing the
                  bell.
           **show-mode-in-prompt (Off)**
                  If set to **On** , add a string to the beginning of the prompt
                  indicating the editing mode: emacs, vi command, or vi
                  insertion.  The mode strings are user-settable (e.g.,
                  _emacs-mode-string_).
           **skip-completed-text (Off)**
                  If set to **On** , this alters the default completion behavior
                  when inserting a single match into the line.  It's only
                  active when performing completion in the middle of a word.
                  If enabled, **readline** does not insert characters from the
                  completion that match characters after point in the word
                  being completed, so portions of the word following the
                  cursor are not duplicated.
           **vi-cmd-mode-string ((cmd))**
                  If the _show-mode-in-prompt_ variable is enabled, this string
                  is displayed immediately before the last line of the
                  primary prompt when vi editing mode is active and in
                  command mode.  The value is expanded like a key binding, so
                  the standard set of meta- and control- prefixes and
                  backslash escape sequences is available.  The \1 and \2
                  escapes begin and end sequences of non-printing characters,
                  which can be used to embed a terminal control sequence into
                  the mode string.
           **vi-ins-mode-string ((ins))**
                  If the _show-mode-in-prompt_ variable is enabled, this string
                  is displayed immediately before the last line of the
                  primary prompt when vi editing mode is active and in
                  insertion mode.  The value is expanded like a key binding,
                  so the standard set of meta- and control- prefixes and
                  backslash escape sequences is available.  The \1 and \2
                  escapes begin and end sequences of non-printing characters,
                  which can be used to embed a terminal control sequence into
                  the mode string.
           **visible-stats (Off)**
                  If set to **On** , a character denoting a file's type as
                  reported by stat(2) is appended to the filename when
                  listing possible completions.
    
       **Conditional Constructs**
           **Readline** implements a facility similar in spirit to the
           conditional compilation features of the C preprocessor which
           allows key bindings and variable settings to be performed as the
           result of tests.  There are four parser directives available.
    
           **$if** The **$if** construct allows bindings to be made based on the
                  editing mode, the terminal being used, or the application
                  using **readline**.  The text of the test, after any comparison
                  operator, extends to the end of the line; unless otherwise
                  noted, no characters are required to isolate it.
    
                  **mode** The **mode=** form of the **$if** directive is used to test
                         whether **readline** is in emacs or vi mode.  This may
                         be used in conjunction with the **set keymap** command,
                         for instance, to set bindings in the _emacs-standard_
                         and _emacs-ctlx_ keymaps only if **readline** is starting
                         out in emacs mode.
    
                  **term** The **term=** form may be used to include terminal-
                         specific key bindings, perhaps to bind the key
                         sequences output by the terminal's function keys.
                         The word on the right side of the **=** is tested
                         against both the full name of the terminal and the
                         portion of the terminal name before the first **-**.
                         This allows _xterm_ to match both _xterm_ and
                         _xterm-256color_ , for instance.
    
                  **version**
                         The **version** test may be used to perform comparisons
                         against specific **readline** versions.  The **version**
                         expands to the current **readline** version.  The set of
                         comparison operators includes **=** , (and **==**), **!=** , **< =**,
                         **> =**, **<** , and **>**.  The version number supplied on the
                         right side of the operator consists of a major
                         version number, an optional decimal point, and an
                         optional minor version (e.g., **7.1**).  If the minor
                         version is omitted, it defaults to **0**.  The operator
                         may be separated from the string **version** and from
                         the version number argument by whitespace.
    
                  _application_
                         The _application_ construct is used to include
                         application-specific settings.  Each program using
                         the **readline** library sets the _application name_ , and
                         an initialization file can test for a particular
                         value.  This could be used to bind key sequences to
                         functions useful for a specific program.  For
                         instance, the following command adds a key sequence
                         that quotes the current or previous word in **bash** :
    
                         **$if** Bash
                         # Quote the current or previous word
                         "\C-xq": "\eb\"\ef\""
                         **$endif**
    
                  _variable_
                         The _variable_ construct provides simple equality
                         tests for **readline** variables and values.  The
                         permitted comparison operators are _=_ , _==_ , and _!=_.
                         The variable name must be separated from the
                         comparison operator by whitespace; the operator may
                         be separated from the value on the right hand side
                         by whitespace.  String and boolean variables may be
                         tested.  Boolean variables must be tested against
                         the values _on_ and _off_.
    
           **$else** Commands in this branch of the **$if** directive are executed
                  if the test fails.
    
           **$endif** This command, as seen in the previous example, terminates
                  an **$if** command.
    
           **$include**
                  This directive takes a single filename as an argument and
                  reads commands and key bindings from that file.  For
                  example, the following directive would read _/etc/inputrc_ :
    
                  **$include** _/etc/inputrc_
    


## SEARCHING



           **Readline** provides commands for searching through the command
           history for lines containing a specified string.  There are two
           search modes: _incremental_ and _non-incremental_.
    
           Incremental searches begin before the user has finished typing the
           search string.  As each character of the search string is typed,
           **readline** displays the next entry from the history matching the
           string typed so far.  An incremental search requires only as many
           characters as needed to find the desired history entry.  When
           using emacs editing mode, type **C-r** to search backward in the
           history for a particular string.  Typing **C-s** searches forward
           through the history.  The characters present in the value of the
           **isearch-terminators** variable are used to terminate an incremental
           search.  If that variable has not been assigned a value, _ESC_ and
           **C-j** terminate an incremental search.  **C-g** aborts an incremental
           search and restores the original line.  When the search is
           terminated, the history entry containing the search string becomes
           the current line.
    
           To find other matching entries in the history list, type **C-r** or
           **C-s** as appropriate.  This searches backward or forward in the
           history for the next entry matching the search string typed so
           far.  Any other key sequence bound to a **readline** command
           terminates the search and executes that command.  For instance, a
           newline terminates the search and accepts the line, thereby
           executing the command from the history list.  A movement command
           will terminate the search, make the last line found the current
           line, and begin editing.
    
           **Readline** remembers the last incremental search string.  If two
           **C-r** s are typed without any intervening characters defining a new
           search string, **readline** uses any remembered search string.
    
           Non-incremental searches read the entire search string before
           starting to search for matching history entries.  The search
           string may be typed by the user or be part of the contents of the
           current line.
    


## EDITING COMMANDS



           The following is a list of the names of the commands and the
           default key sequences to which they are bound.  Command names
           without an accompanying key sequence are unbound by default.
    
           In the following descriptions, _point_ refers to the current cursor
           position, and _mark_ refers to a cursor position saved by the
           **set-mark** command.  The text between the point and mark is referred
           to as the _region_.  **Readline** has the concept of an _active region_ :
           when the region is active, **readline** redisplay highlights the
           region using the value of the **active-region-start-color** variable.
           The **enable-active-region** variable turns this on and off.  Several
           commands set the region to active; those are noted below.
    
       **Commands for Moving**
           **beginning-of-line (C-a)**
                  Move to the start of the current line.  This may also be
                  bound to the Home key on some keyboards.
           **end-of-line (C-e)**
                  Move to the end of the line.  This may also be bound to the
                  End key on some keyboards.
           **forward-char (C-f)**
                  Move forward a character.  This may also be bound to the
                  right arrow key on some keyboards.
           **backward-char (C-b)**
                  Move back a character.
           **forward-word (M-f)**
                  Move forward to the end of the next word.  Words are
                  composed of alphanumeric characters (letters and digits).
           **backward-word (M-b)**
                  Move back to the start of the current or previous word.
                  Words are composed of alphanumeric characters (letters and
                  digits).
           **previous-screen-line**
                  Attempt to move point to the same physical screen column on
                  the previous physical screen line.  This will not have the
                  desired effect if the current **readline** line does not take
                  up more than one physical line or if point is not greater
                  than the length of the prompt plus the screen width.
           **next-screen-line**
                  Attempt to move point to the same physical screen column on
                  the next physical screen line.  This will not have the
                  desired effect if the current **readline** line does not take
                  up more than one physical line or if the length of the
                  current **readline** line is not greater than the length of the
                  prompt plus the screen width.
           **clear-display (M-C-l)**
                  Clear the screen and, if possible, the terminal's
                  scrollback buffer, then redraw the current line, leaving
                  the current line at the top of the screen.
           **clear-screen (C-l)**
                  Clear the screen, then redraw the current line, leaving the
                  current line at the top of the screen.  With a numeric
                  argument, refresh the current line without clearing the
                  screen.
           **redraw-current-line**
                  Refresh the current line.
    
       **Commands for Manipulating the History**
           **accept-line (Newline, Return)**
                  Accept the line regardless of where the cursor is.  If this
                  line is non-empty, it may be added to the history list for
                  future recall with **add_history()**.  If the line is a
                  modified history line, restore the history line to its
                  original state.
           **previous-history (C-p)**
                  Fetch the previous command from the history list, moving
                  back in the list.  This may also be bound to the up arrow
                  key on some keyboards.
           **next-history (C-n)**
                  Fetch the next command from the history list, moving
                  forward in the list.  This may also be bound to the down
                  arrow key on some keyboards.
           **beginning-of-history (M- <)**
                  Move to the first line in the history.
           **end-of-history (M- >)**
                  Move to the end of the input history, i.e., the line
                  currently being entered.
           **operate-and-get-next (C-o)**
                  Accept the current line for return to the calling
                  application as if a newline had been entered, and fetch the
                  next line relative to the current line from the history for
                  editing.  A numeric argument, if supplied, specifies the
                  history entry to use instead of the current line.
           **fetch-history**
                  With a numeric argument, fetch that entry from the history
                  list and make it the current line.  Without an argument,
                  move back to the first entry in the history list.
           **reverse-search-history (C-r)**
                  Search backward starting at the current line and moving
                  “up” through the history as necessary.  This is an
                  incremental search.  This command sets the region to the
                  matched text and activates the region.
           **forward-search-history (C-s)**
                  Search forward starting at the current line and moving
                  “down” through the history as necessary.  This is an
                  incremental search.  This command sets the region to the
                  matched text and activates the region.
           **non-incremental-reverse-search-history (M-p)**
                  Search backward through the history starting at the current
                  line using a non-incremental search for a string supplied
                  by the user.  The search string may match anywhere in a
                  history line.
           **non-incremental-forward-search-history (M-n)**
                  Search forward through the history using a non-incremental
                  search for a string supplied by the user.  The search
                  string may match anywhere in a history line.
           **history-search-backward**
                  Search backward through the history for the string of
                  characters between the start of the current line and the
                  point.  The search string must match at the beginning of a
                  history line.  This is a non-incremental search.  This may
                  be bound to the Page Up key on some keyboards.
           **history-search-forward**
                  Search forward through the history for the string of
                  characters between the start of the current line and the
                  point.  The search string must match at the beginning of a
                  history line.  This is a non-incremental search.  This may
                  be bound to the Page Down key on some keyboards.
           **history-substring-search-backward**
                  Search backward through the history for the string of
                  characters between the start of the current line and the
                  point.  The search string may match anywhere in a history
                  line.  This is a non-incremental search.
           **history-substring-search-forward**
                  Search forward through the history for the string of
                  characters between the start of the current line and the
                  point.  The search string may match anywhere in a history
                  line.  This is a non-incremental search.
           **yank-nth-arg (M-C-y)**
                  Insert the first argument to the previous command (usually
                  the second word on the previous line) at point.  With an
                  argument _n_ , insert the _n_ th word from the previous command
                  (the words in the previous command begin with word 0).  A
                  negative argument inserts the _n_ th word from the end of the
                  previous command.  Once the argument _n_ is computed, this
                  uses the history expansion facilities to extract the _n_ th
                  word, as if the “!_n_ ” history expansion had been specified.
           **yank-last-arg (M-., M-_)**
                  Insert the last argument to the previous command (the last
                  word of the previous history entry).  With a numeric
                  argument, behave exactly like **yank-nth-arg**.  Successive
                  calls to **yank-last-arg** move back through the history list,
                  inserting the last word (or the word specified by the
                  argument to the first call) of each line in turn.  Any
                  numeric argument supplied to these successive calls
                  determines the direction to move through the history.  A
                  negative argument switches the direction through the
                  history (back or forward).  This uses the history expansion
                  facilities to extract the last word, as if the “!$” history
                  expansion had been specified.
    
       **Commands for Changing Text**
           _end-of-file_ **(usually C-d)**
                  The character indicating end-of-file as set, for example,
                  by stty(1).  If this character is read when there are no
                  characters on the line, and point is at the beginning of
                  the line, **readline** interprets it as the end of input and
                  returns **EOF**.
           **delete-char (C-d)**
                  Delete the character at point.  If this function is bound
                  to the same character as the tty **EOF** character, as **C-d**
                  commonly is, see above for the effects.  This may also be
                  bound to the Delete key on some keyboards.
           **backward-delete-char (Rubout)**
                  Delete the character behind the cursor.  When given a
                  numeric argument, save the deleted text on the kill ring.
           **forward-backward-delete-char**
                  Delete the character under the cursor, unless the cursor is
                  at the end of the line, in which case the character behind
                  the cursor is deleted.
           **quoted-insert (C-q, C-v)**
                  Add the next character typed to the line verbatim.  This is
                  how to insert characters like **C-q** , for example.
           **tab-insert (M-TAB)**
                  Insert a tab character.
           **self-insert (a, b, A, 1, !,**...**)**
                  Insert the character typed.
           **bracketed-paste-begin**
                  This function is intended to be bound to the “bracketed
                  paste” escape sequence sent by some terminals, and such a
                  binding is assigned by default.  It allows **readline** to
                  insert the pasted text as a single unit without treating
                  each character as if it had been read from the keyboard.
                  The pasted characters are inserted as if each one was bound
                  to **self-insert** instead of executing any editing commands.
                  Bracketed paste sets the region to the inserted text and
                  activates the region.
           **transpose-chars (C-t)**
                  Drag the character before point forward over the character
                  at point, moving point forward as well.  If point is at the
                  end of the line, then this transposes the two characters
                  before point.  Negative arguments have no effect.
           **transpose-words (M-t)**
                  Drag the word before point past the word after point,
                  moving point past that word as well.  If point is at the
                  end of the line, this transposes the last two words on the
                  line.
           **upcase-word (M-u)**
                  Uppercase the current (or following) word.  With a negative
                  argument, uppercase the previous word, but do not move
                  point.
           **downcase-word (M-l)**
                  Lowercase the current (or following) word.  With a negative
                  argument, lowercase the previous word, but do not move
                  point.
           **capitalize-word (M-c)**
                  Capitalize the current (or following) word.  With a
                  negative argument, capitalize the previous word, but do not
                  move point.
           **overwrite-mode**
                  Toggle overwrite mode.  With an explicit positive numeric
                  argument, switches to overwrite mode.  With an explicit
                  non-positive numeric argument, switches to insert mode.
                  This command affects only **emacs** mode; **vi** mode does
                  overwrite differently.  Each call to _readline()_ starts in
                  insert mode.
                  In overwrite mode, characters bound to **self-insert** replace
                  the text at point rather than pushing the text to the
                  right.  Characters bound to **backward-delete-char** replace
                  the character before point with a space.  By default, this
                  command is unbound, but may be bound to the Insert key on
                  some keyboards.
    
       **Killing and Yanking**
           **kill-line (C-k)**
                  Kill the text from point to the end of the current line.
                  With a negative numeric argument, kill backward from the
                  cursor to the beginning of the line.
           **backward-kill-line (C-x Rubout)**
                  Kill backward to the beginning of the current line.  With a
                  negative numeric argument, kill forward from the cursor to
                  the end of the line.
           **unix-line-discard (C-u)**
                  Kill backward from point to the beginning of the line,
                  saving the killed text on the kill-ring.
           **kill-whole-line**
                  Kill all characters on the current line, no matter where
                  point is.
           **kill-word (M-d)**
                  Kill from point to the end of the current word, or if
                  between words, to the end of the next word.  Word
                  boundaries are the same as those used by **forward-word**.
           **backward-kill-word (M-Rubout)**
                  Kill the word behind point.  Word boundaries are the same
                  as those used by **backward-word**.
           **unix-word-rubout (C-w)**
                  Kill the word behind point, using white space as a word
                  boundary, saving the killed text on the kill-ring.
           **unix-filename-rubout**
                  Kill the word behind point, using white space and the slash
                  character as the word boundaries, saving the killed text on
                  the kill-ring.
           **delete-horizontal-space (M-\)**
                  Delete all spaces and tabs around point.
           **kill-region**
                  Kill the text in the current region.
           **copy-region-as-kill**
                  Copy the text in the region to the kill buffer, so it can
                  be yanked immediately.
           **copy-backward-word**
                  Copy the word before point to the kill buffer.  The word
                  boundaries are the same as **backward-word**.
           **copy-forward-word**
                  Copy the word following point to the kill buffer.  The word
                  boundaries are the same as **forward-word**.
           **yank (C-y)**
                  Yank the top of the kill ring into the buffer at point.
           **yank-pop (M-y)**
                  Rotate the kill ring, and yank the new top.  Only works
                  following **yank** or **yank-pop**.
    
       **Numeric Arguments**
           **digit-argument (M-0, M-1,**...**, M--)**
                  Add this digit to the argument already accumulating, or
                  start a new argument.  M-- starts a negative argument.
           **universal-argument**
                  This is another way to specify an argument.  If this
                  command is followed by one or more digits, optionally with
                  a leading minus sign, those digits define the argument.  If
                  the command is followed by digits, executing
                  **universal-argument** again ends the numeric argument, but is
                  otherwise ignored.  As a special case, if this command is
                  immediately followed by a character that is neither a digit
                  nor minus sign, the argument count for the next command is
                  multiplied by four.  The argument count is initially one,
                  so executing this function the first time makes the
                  argument count four, a second time makes the argument count
                  sixteen, and so on.
    
       **Completing**
           **complete (TAB)**
                  Attempt to perform completion on the text before point.
                  The actual completion performed is application-specific.
                  **Bash** , for instance, attempts programmable completion first,
                  otherwise treating the text as a variable (if the text
                  begins with **$**), username (if the text begins with **~**),
                  hostname (if the text begins with **@**), or command (including
                  aliases, functions, and builtins) in turn.  If none of
                  these produces a match, it falls back to filename
                  completion.  **Gdb** , on the other hand, allows completion of
                  program functions and variables, and only attempts filename
                  completion under certain circumstances.  The default
                  **readline** completion is filename completion.
           **possible-completions (M-?)**
                  List the possible completions of the text before point.
                  When displaying completions, **readline** sets the number of
                  columns used for display to the value of **completion-**
                  **display-width** , the value of the environment variable
                  **COLUMNS** , or the screen width, in that order.
           **insert-completions (M-*)**
                  Insert all completions of the text before point that would
                  have been generated by **possible-completions** , separated by a
                  space.
           **menu-complete**
                  Similar to **complete** , but replaces the word to be completed
                  with a single match from the list of possible completions.
                  Repeatedly executing **menu-complete** steps through the list
                  of possible completions, inserting each match in turn.  At
                  the end of the list of completions, **menu-complete** rings the
                  bell (subject to the setting of **bell-style**) and restores
                  the original text.  An argument of _n_ moves _n_ positions
                  forward in the list of matches; a negative argument moves
                  backward through the list.  This command is intended to be
                  bound to **TAB** , but is unbound by default.
           **menu-complete-backward**
                  Identical to **menu-complete** , but moves backward through the
                  list of possible completions, as if **menu-complete** had been
                  given a negative argument.  This command is unbound by
                  default.
           **export-completions**
                  Perform completion on the word before point as described
                  above and write the list of possible completions to
                  **readline** 's output stream using the following format,
                  writing information on separate lines:
    
                  •      the number of matches _N_ ;
                  •      the word being completed;
                  •      _S_ :_E_ , where _S_ and _E_ are the start and end offsets of
                         the word in the **readline** line buffer; then
                  •      each match, one per line
    
                  If there are no matches, the first line will be “0”, and
                  this command does not print any output after the _S_ :_E_.  If
                  there is only a single match, this prints a single line
                  containing it.  If there is more than one match, this
                  prints the common prefix of the matches, which may be
                  empty, on the first line after the _S_ :_E_ , then the matches on
                  subsequent lines.  In this case, _N_ will include the first
                  line with the common prefix.
    
                  The user or application should be able to accommodate the
                  possibility of a blank line.  The intent is that the user
                  or application reads _N_ lines after the line containing _S_ :_E_
                  to obtain the match list.  This command is unbound by
                  default.
    
           **delete-char-or-list**
                  Deletes the character under the cursor if not at the
                  beginning or end of the line (like **delete-char**).  At the
                  end of the line, it behaves identically to
                  **possible-completions**.  This command is unbound by default.
    
       **Keyboard Macros**
           **start-kbd-macro (C-x ()**
                  Begin saving the characters typed into the current keyboard
                  macro.
           **end-kbd-macro (C-x ))**
                  Stop saving the characters typed into the current keyboard
                  macro and store the definition.
           **call-last-kbd-macro (C-x e)**
                  Re-execute the last keyboard macro defined, by making the
                  characters in the macro appear as if typed at the keyboard.
           **print-last-kbd-macro ()**
                  Print the last keyboard macro defined in a format suitable
                  for the _inputrc_ file.
    
       **Miscellaneous**
           **re-read-init-file (C-x C-r)**
                  Read in the contents of the _inputrc_ file, and incorporate
                  any bindings or variable assignments found there.
           **abort (C-g)**
                  Abort the current editing command and ring the terminal's
                  bell (subject to the setting of **bell-style**).
           **do-lowercase-version (M-A, M-B, M-**_x_**,**...**)**
                  If the metafied character _x_ is uppercase, run the command
                  that is bound to the corresponding metafied lowercase
                  character.  The behavior is undefined if _x_ is already
                  lowercase.
           **prefix-meta (ESC)**
                  Metafy the next character typed.  **ESC f** is equivalent to
                  **Meta-f**.
           **undo (C-_, C-x C-u)**
                  Incremental undo, separately remembered for each line.
           **revert-line (M-r)**
                  Undo all changes made to this line.  This is like executing
                  the **undo** command enough times to return the line to its
                  initial state.
           **tilde-expand (M-~)**
                  Perform tilde expansion on the current word.
           **set-mark (C-@, M- <space>)**
                  Set the mark to the point.  If a numeric argument is
                  supplied, set the mark to that position.
           **exchange-point-and-mark (C-x C-x)**
                  Swap the point with the mark.  Set the current cursor
                  position to the saved position, then set the mark to the
                  old cursor position.
           **character-search (C-])**
                  Read a character and move point to the next occurrence of
                  that character.  A negative argument searches for previous
                  occurrences.
           **character-search-backward (M-C-])**
                  Read a character and move point to the previous occurrence
                  of that character.  A negative argument searches for
                  subsequent occurrences.
           **skip-csi-sequence**
                  Read enough characters to consume a multi-key sequence such
                  as those defined for keys like Home and End.  CSI sequences
                  begin with a Control Sequence Indicator (CSI), usually _ESC_
                  _[_.  If this sequence is bound to “\e[”, keys producing CSI
                  sequences have no effect unless explicitly bound to a
                  **readline** command, instead of inserting stray characters
                  into the editing buffer.  This is unbound by default, but
                  usually bound to _ESC [_.
           **insert-comment (M-#)**
                  Without a numeric argument, insert the value of the
                  **readline comment-begin** variable at the beginning of the
                  current line.  If a numeric argument is supplied, this
                  command acts as a toggle: if the characters at the
                  beginning of the line do not match the value of
                  **comment-begin** , insert the value; otherwise delete the
                  characters in **comment-begin** from the beginning of the line.
                  In either case, the line is accepted as if a newline had
                  been typed.  The default value of **comment-begin** causes this
                  command to make the current line a shell comment.  If a
                  numeric argument causes the comment character to be
                  removed, the line will be executed by the shell.
           **dump-functions**
                  Print all of the functions and their key bindings to the
                  **readline** output stream.  If a numeric argument is supplied,
                  the output is formatted in such a way that it can be made
                  part of an _inputrc_ file.
           **dump-variables**
                  Print all of the settable variables and their values to the
                  **readline** output stream.  If a numeric argument is supplied,
                  the output is formatted in such a way that it can be made
                  part of an _inputrc_ file.
           **dump-macros**
                  Print all of the **readline** key sequences bound to macros and
                  the strings they output to the **readline** output stream.  If
                  a numeric argument is supplied, the output is formatted in
                  such a way that it can be made part of an _inputrc_ file.
           **execute-named-command (M-x)**
                  Read a bindable **readline** command name from the input and
                  execute the function to which it's bound, as if the key
                  sequence to which it was bound appeared in the input.  If
                  this function is supplied with a numeric argument, it
                  passes that argument to the function it executes.
           **emacs-editing-mode (C-e)**
                  When in **vi** command mode, this switches **readline** to **emacs**
                  editing mode.
           **vi-editing-mode (M-C-j)**
                  When in **emacs** editing mode, this switches to **vi** editing
                  mode.
    


## DEFAULT KEY BINDINGS



           The following is a list of the default emacs and vi bindings.
           Characters with the eighth bit set are written as M-<character>,
           and are referred to as _metafied_ characters.  The printable ASCII
           characters not mentioned in the list of emacs standard bindings
           are bound to the **self-insert** function, which just inserts the
           given character into the input line.  In vi insertion mode, all
           characters not specifically mentioned are bound to **self-insert**.
           Characters assigned to signal generation by stty(1) or the
           terminal driver, such as C-Z or C-C, retain that function.  Upper
           and lower case metafied characters are bound to the same function
           in the emacs mode meta keymap.  The remaining characters are
           unbound, which causes **readline** to ring the bell (subject to the
           setting of the **bell-style** variable).
