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 _m_a_l_l_o_c(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
_e_m_a_c_s__k_e_y_m_a_p, _e_m_a_c_s__m_e_t_a__k_e_y_m_a_p, _e_m_a_c_s__c_t_l_x__k_e_y_m_a_p,
_v_i__i_n_s_e_r_t_i_o_n__k_e_y_m_a_p, _o_r _v_i__m_o_v_e_m_e_n_t__k_e_y_m_a_p.
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.

READLINE(3) C LIBRARY FUNCTIONS READLINE(3)
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-_k_e_y, e.g., C-n means Control-N.
Similarly, _m_e_t_a keys are denoted by M-_k_e_y, so M-x means
GNU Last change: 1994 July 26 3
READLINE(3) C LIBRARY FUNCTIONS READLINE(3)
Meta-X. (On keyboards without a _m_e_t_a key, M-_x means ESC _x,
i.e., press the Escape key then the _x key. This makes ESC
the _m_e_t_a _p_r_e_f_i_x. 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 _a_r_g_u_m_e_n_t_s, 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 _k_i_l_l_i_n_g text, the text
deleted is saved for possible future retrieval (_y_a_n_k_i_n_g).
The killed text is saved in a _k_i_l_l-_r_i_n_g. 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 ~/._i_n_p_u_t_r_c. 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 ~/._i_n_p_u_t_r_c would make M-C-u execute the readline
command _u_n_i_v_e_r_s_a_l-_a_r_g_u_m_e_n_t.
The following symbolic character names are recognized while
processing key bindings: _R_U_B_O_U_T, _D_E_L, _E_S_C, _L_F_D, _N_E_W_L_I_N_E,
_R_E_T, _R_E_T_U_R_N, _S_P_C, _S_P_A_C_E, and _T_A_B. In addition to command
names, readline allows keys to be bound to a string that is
inserted when the key is pressed (a _m_a_c_r_o).
Key Bindings
The syntax for controlling key bindings in the ~/._i_n_p_u_t_r_c
file is simple. All that is required is the name of the
GNU Last change: 1994 July 26 4
READLINE(3) C LIBRARY FUNCTIONS READLINE(3)
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 _M_e_t_a- or _C_o_n_-
_t_r_o_l- prefixes, or as a key sequence. When using the form
keyname:_f_u_n_c_t_i_o_n-_n_a_m_e or _m_a_c_r_o, _k_e_y_n_a_m_e 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-_D_E_L 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 >&_o_u_t_p_u_t into the line).
In the second form, "keyseq":_f_u_n_c_t_i_o_n-_n_a_m_e or _m_a_c_r_o, 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 _E_S_C [ _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
GNU Last change: 1994 July 26 5
READLINE(3) C LIBRARY FUNCTIONS READLINE(3)
the -o option to the set builtin command. Other programs
using this library provide similar mechanisms. The _i_n_p_u_t_r_c
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 _i_n_p_u_t_r_c file
with a statement of the form
set _v_a_r_i_a_b_l_e-_n_a_m_e _v_a_l_u_e
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 _e_m_a_c_s or _v_i. 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 _m_e_t_a _p_r_e_f_i_x).
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
GNU Last change: 1994 July 26 6
READLINE(3) C LIBRARY FUNCTIONS READLINE(3)
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 _e_m_a_c_s, _e_m_a_c_s-_s_t_a_n_d_a_r_d, _e_m_a_c_s-_m_e_t_a, _e_m_a_c_s-
_c_t_l_x, _v_i, _v_i-_m_o_v_e, _v_i-_c_o_m_m_a_n_d, and _v_i-_i_n_s_e_r_t. _v_i is
equivalent to _v_i-_c_o_m_m_a_n_d; _e_m_a_c_s is equivalent to
_e_m_a_c_s-_s_t_a_n_d_a_r_d. The default value is _e_m_a_c_s; 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
_e_m_a_c_s-_s_t_a_n_d_a_r_d and _e_m_a_c_s-_c_t_l_x 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 _s_u_n to match both _s_u_n and _s_u_n-_c_m_d, for
instance.
GNU Last change: 1994 July 26 7
READLINE(3) C LIBRARY FUNCTIONS READLINE(3)
application
The application construct is used to include
application-specific settings. Each program using
the readline library sets the _a_p_p_l_i_c_a_t_i_o_n _n_a_m_e,
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.
GNU Last change: 1994 July 26 8
READLINE(3) C LIBRARY FUNCTIONS READLINE(3)
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-_)
GNU Last change: 1994 July 26 9
READLINE(3) C LIBRARY FUNCTIONS READLINE(3)
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
GNU Last change: 1994 July 26 10
READLINE(3) C LIBRARY FUNCTIONS READLINE(3)
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
GNU Last change: 1994 July 26 11
READLINE(3) C LIBRARY FUNCTIONS READLINE(3)
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 _i_n_p_u_t_r_c 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 _m_e_t_a_f_i_e_d characters.
The printable ASCII characters not mentioned in the list of
GNU Last change: 1994 July 26 12
READLINE(3) C LIBRARY FUNCTIONS READLINE(3)
emacs standard bindings are bound to the _s_e_l_f-_i_n_s_e_r_t func-
tion, which just inserts the given character into the input
line. In vi insertion mode, all characters not specifically
mentioned are bound to _s_e_l_f-_i_n_s_e_r_t. Characters assigned to
signal generation by _s_t_t_y(1) or the terminal driver, such as
C-Z or C-C, retain that function. Upper and lower case
_m_e_t_a_f_i_e_d 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).
