DESCRIPTION

readline will read a line from the terminal and  return  it,
     using  prompt  as a prompt.  If prompt is null, no prompt is
     issued.  The line returned is allocated with  malloc(3),  so
     the  caller  must  free it when finished.  The line returned
     has the final newline removed, so only the text of the  line
     remains.

     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.

     In  the  following  descriptions,  keymap  can  be  one   of
     emacs_keymap,      emacs_meta_keymap,     emacs_ctlx_keymap,
     vi_insertion_keymap, or vi_movement_keymap.

     rl_add_defun makes name appear as a bindable  readline  com-
     mand,  and  makes  function be the function called when that
     command is invoked.  If key is not -1, it is bound to  func-
     tion in the current keymap.

     rl_bind_key causes key to invoke function.  The  binding  is
     made in the current keymap.

     rl_unbind_key removes the binding for  key  in  the  current
     keymap.

     rl_bind_key_in_map makes the  key  entry  in  keymap  invoke
     function.

     rl_unbind_key_in_map removes the binding for key  in  keymap
     keymap.


     rl_macro_bind makes keyseq insert  the  string  macro.   The
     binding is performed in keymap.

     rl_variable_bind sets the value  of  the  readline  variable
     variable to value.

     rl_parse_and_bind takes as an argument a line  of  the  same
     form  as  the readline startup file (see INITIALIZATION FILE
     below) and executes the commands therein.

     rl_translate_keyseq converts keyseq into a new string, stor-
     ing  the  result in array.  This translates control and meta
     prefixes and the readline character  escape  sequences  (see
     Key  Bindings below).  The length of the translated sequence
     is returned in *len.

     rl_named_function returns the function that is executed when
     the readline command command is invoked.

     rl_function_of_keyseq returns the function that is  executed
     when  keyseq is read and keymap is the current keymap.  type
     is set to indicate whether the return value corresponds to a
     function, macro, or auxiliary keymap.

     rl_invoking_keyseqs returns all of the key sequences in  the
     current keymap that invoke function.

     rl_invoking_keyseqs_in_map returns all of the key  sequences
     in keymap that invoke function.

     rl_function_dumper prints all of the readline functions  and
     their  bindings  to the readline output stream.  If readable
     is non-zero, the output is formattted so that it can be read
     back in to restore the bindings.

     rl_funmap_names returns an array of all known readline bind-
     able function names.  The array is sorted.

RETURN VALUE

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

     Unless otherwise stated, the other  functions  return  0  on
     success and non-zero on failure.

NOTATION

An emacs-style notation is used to denote keystrokes.   Con-
     trol  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.   (On keyboards without a meta key, M-x means ESC x,
     i.e., press the Escape key then the x key.  This  makes  ESC
     the meta prefix.  The combination M-C-x means ESC-Control-x,
     or press the Escape key then  hold  the  Control  key  while
     pressing the x key.)

     Readline commands may be given numeric arguments, which nor-
     mally  act as a repeat count.  Sometimes, however, it is the
     sign of the argument that is significant.  Passing  a  nega-
     tive  argument  to a command that acts in the forward direc-
     tion (e.g., kill-line) causes that command to act in a back-
     ward  direction.   Commands  whose  behavior  with arguments
     deviates from this are noted.

     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
     cause the text to be accumulated 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 initializa-
     tion file.  The name of this file is taken from the value of
     the INPUTRC  variable.   If  that  variable  is  unset,  the
     default  is ~/.inputrc.  When a program which uses the read-
     line library starts up, the init file is read, and  the  key
     bindings  and variables are set.  There are only a few basic
     constructs allowed in the readline init 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.  Each pro-
     gram using this library may add its own commands  and  bind-
     ings.

     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.

     The following symbolic character names are recognized  while
     processing  key  bindings:  RUBOUT,  DEL, ESC, LFD, NEWLINE,
     RET, RETURN, SPC, SPACE, 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).

  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 name may be specified in one of two
     ways: as a symbolic key name, possibly with  Meta-  or  Con-
     trol-  prefixes,  or as a key sequence.  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.

          "\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 escape sequences is

          \C-  control prefix

          \M-  meta prefix

          \e   an escape character

          \\   backslash

          " \" literal "

          \'   literal '

     When entering the text of a macro, single or  double  quotes
     should  be  used  to  indicate a macro definition.  Unquoted
     text is assumed to be a function name.  Backslash will quote
     any character in the macro text, including " and '.

     Bash  allows  the  current  readline  key  bindings  to   be
     displayed  or  modified  with the bind builtin command.  The
     editing mode may be switched during interactive use by using            
the  -o  option  to the set builtin command.  Other programs
     using this library provide similar mechanisms.  The  inputrc
     file may be edited and re-read 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.  The variables and their default values are:

     horizontal-scroll-mode (Off)
          When set 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.
     editing-mode (emacs)
          Controls whether readline begins  with  a  set  of  key
          bindings  similar  to emacs or vi.  editing-mode can be
          set to either emacs or vi.
     mark-modified-lines (Off)
          If set to On, history lines that have been modified are
          displayed with a preceding asterisk (*).
     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.
     comment-begin (``#'')
          The string  that  is  inserted  in  vi  mode  when  the
          vi-comment command is executed.
     meta-flag (Off)
          If set to On,  readline  will  enable  eight-bit  input
          (that is, it will not strip the high bit from the char-
          acters it  reads),  regardless  of  what  the  terminal
          claims it can support.
     convert-meta (On)
          If set to On, readline will convert characters with the
          eighth  bit  set  to an ASCII key sequence by stripping
          the eighth bit and prepending an escape  character  (in
          effect, using escape as the meta prefix).
     output-meta (Off)
          If set to On, readline will display characters with the
          eighth  bit set directly rather than as a meta-prefixed
          escape sequence.
     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,  the  user is asked
          whether or not he wishes to view them;  otherwise  they
          are simply listed on the terminal.
     keymap (emacs)
          Set the current readline keymap.  The set of legal key-
          map  names is emacs, emacs-standard, emacs-meta, emacs-
          ctlx, vi, vi-move, 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.
     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.
     expand-tilde (Off)
          If set to on, tilde expansion is performed  when  read-
          line attempts word completion.

  Conditional Constructs
     Readline implements a facility similar in spirit to the con-
     ditional  compilation  features  of the C preprocessor which
     allows key bindings and variable settings to be performed as
     the  result  of  tests.   There  are three parser directives
     used.

     $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
          extends  to  the  end  of  the  line; 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  key-
               map  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 the full name of the terminal and the por-
               tion  of  the  terminal  name  before the first -.
               This allows sun to match both sun and sun-cmd, for
               instance.



          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 particu-
               lar  value.   This  could  be  used  to  bind  key
               sequences  to functions useful for a specific pro-
               gram.  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

     $endif
          This command, as you saw in the previous example,  ter-
          minates an $if command.

     $else
          Commands in this branch of the $if directive  are  exe-
          cuted if the test fails.

EDITING COMMANDS

The following is a list of the names of the commands and the
     default key sequences to which they are bound.

  Commands for Moving
     beginning-of-line (C-a)
          Move to the start of the current line.
     end-of-line (C-e)
          Move to the end of the line.
     forward-char (C-f)
          Move forward a character.
     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 this, or the previous,  word.
          Words  are composed of alphanumeric characters (letters
          and digits).
     clear-screen (C-l)
          Clear the screen leaving the current line at the top of
          the screen.  With an argument, refresh the current line
          without clearing the screen.
     redraw-current-line
          Refresh the current line.  By default, this is unbound.




  Commands for Manipulating the History
     accept-line (Newline, Return)
          Accept the line regardless of where the cursor is.   If
          this  line is non-empty, add it to the history list. If
          the line is a modified history line, then  restore  the
          history line to its original state.
     previous-history (C-p)
          Fetch the previous command from the history list,  mov-
          ing back in the list.
     next-history (C-n)
          Fetch the next command from the  history  list,  moving
          forward in the list.
     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.
     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.
     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.
     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.
     non-incremental-forward-search-history (M-n)
          Search   forward   through   the   history   using    a
          non-incremental  search  for  a  string supplied by the
          user.
     history-search-forward
          Search forward through the history for  the  string  of
          characters  between  the  start of the current line and
          the current point.  This is a  non-incremental  search.
          By default, this command is unbound.
     history-search-backward
          Search backward through the history for the  string  of
          characters  between  the  start of the current line and
          the current point.  This is a  non-incremental  search.
          By default, this command is unbound.
     yank-nth-arg (M-C-y)
          Insert the first argument to the previous command (usu-
          ally  the  second  word  on the previous line) at point
          (the current cursor position).   With  an  argument  n,
          insert  the  nth  word  from  the previous command (the
          words in the previous command begin with  word  0).   A
          negative  argument inserts the nth word from the end of
          the previous command.
     yank-last-arg (M-., M-_)


          Insert the last argument to the previous  command  (the
          last  word  on  the  previous line).  With an argument,
          behave exactly like yank-nth-arg.

  Commands for Changing Text
     delete-char (C-d)
          Delete the character under the cursor.  If point is  at
          the  beginning  of the line, there are no characters in
          the line, and the last character  typed  was  not  C-d,
          then return EOF.
     backward-delete-char (Rubout)
          Delete the character behind the cursor.  When  given  a
          numeric   argument,   save  the  deleted  text  on  the
          kill-ring.
     quoted-insert (C-q, C-v)
          Add the next character that you type to the line verba-
          tim.   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.
     transpose-chars (C-t)
          Drag the character before point forward over the  char-
          acter at point.  Point moves forward as well.  If point
          is at the end of the line, then transpose the two char-
          acters before point.  Negative arguments don't work.
     transpose-words (M-t)
          Drag the word behind the cursor past the word in  front
          of the cursor moving the cursor over that word as well.
     upcase-word (M-u)
          Uppercase the current  (or  following)  word.   With  a
          negative  argument,  do  the  previous word, but do not
          move point.
     downcase-word (M-l)
          Lowercase the current  (or  following)  word.   With  a
          negative  argument,  do  the  previous word, but do not
          move point.
     capitalize-word (M-c)
          Capitalize the current (or  following)  word.   With  a
          negative  argument,  do  the  previous word, but do not
          move point.

  Killing and Yanking
     kill-line (C-k)
          Kill the text from the current cursor position  to  the
          end of the line.
     backward-kill-line (C-x Rubout)
          Kill backward to the beginning of the line.
     unix-line-discard (C-u)
          Kill backward from point to the beginning of the line.
     kill-whole-line


          Kill all characters on  the  current  line,  no  matter
          where the cursor is.  By default, this is unbound.
     kill-word (M-d)
          Kill from the cursor 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 the cursor.  Word  boundaries  are
          the same as those used by backward-word.
     unix-word-rubout (C-w)
          Kill the word behind the cursor, using white space as a
          word  boundary.  The word boundaries are different from
          backward-kill-word.
     delete-horizontal-space
          Delete all spaces and tabs around point.   By  default,
          this is unbound.
     yank (C-y)
          Yank the top of the kill ring into the  buffer  at  the
          cursor.
     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
          Each time this is executed, the argument count is  mul-
          tiplied  by four.  The argument count is initially one,
          so executing this function the  first  time  makes  the
          argument  count four.  By default, this is not bound to
          a key.

  Completing
     complete (TAB)
          Attempt to perform completion on the text before point.
          The   actual   completion   performed  is  application-
          specific.   Bash,  for  instance,  attempts  completion
          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 and functions) in turn.  If none of these  pro-
          duces  a match, filename completion is attempted.  Gdb,
          on the other hand, allows completion of  program  func-
          tions and variables, and only attempts filename comple-
          tion under certain circumstances.
     possible-completions (M-?)
          List the possible completions of the text before point.
     insert-completions
          Insert all completions of the text  before  point  that
          would  have been generated by possible-completions.  By


          default, this is not bound to a key.

  Keyboard Macros
     start-kbd-macro (C-x ()
          Begin saving the characters typed into the current key-
          board macro.
     end-kbd-macro (C-x ))
          Stop saving the characters typed into the current  key-
          board macro and save 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.

  Miscellaneous
     re-read-init-file (C-x C-r)
          Read in the contents of your init 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-uppercase-version (M-a, M-b, ...)
          Run the command that  is  bound  to  the  corresponding
          uppercase character.
     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  typ-
          ing the undo command enough times to return the line to
          its initial state.
     tilde-expand (M-~)
          Perform tilde expansion on the current word.
     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.
     emacs-editing-mode (C-e)
          When in vi editing mode, this causes a switch to  emacs
          editing mode.
     vi-editing-mode (M-C-j)
          When in emacs editing mode, this causes a switch to  vi
          editing mode.

DEFAULT KEY BINDINGS

The following is a list of the default emacs  and  vi  bind-
     ings.   Characters  with  the  8th 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  func-
     tion,  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).

BUG REPORTS

If you find a bug in readline, you should  report  it.   But
     first,  you  should  make  sure that it really is a bug, and
     that it appears  in  the  latest  version  of  the  readline
     library that you have.

     Once you have determined that a bug actually exists, mail  a
     bug report to bash-maintainers@prep.ai.MIT.Edu.  If you have
     a fix, you are welcome to mail that  as  well!   Suggestions
     and  `philosophical'  bug  reports  may  be  mailed  to bug-
     bash@prep.ai.MIT.Edu  or  posted  to  the  Usenet  newsgroup
     gnu.bash.bug.

     Comments and bug reports concerning this manual page  should
     be directed to chet@ins.CWRU.Edu.
