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
function 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,
storing 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 exe-
cuted 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
bindable 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
reading 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 newline.
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.
Control keys are denoted by C-key, e.g., C-n means Con-
trol-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 Con-
trol key while pressing the x key.)
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) causes that command to act in
a backward direction. Commands whose behavior with argu-
ments 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 initial-
ization 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
readline 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 program using this library may add its 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.
The following symbolic character names are recognized
while processing key bindings: RUBOUT, DEL, ESC, LFD, NEW-
LINE, 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
Control- 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 univer-
sal-argument, M-DEL is bound to the function back-
ward-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, key-
seq 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 uni-
versal-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 dis-
played 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 bind-
ings.
Variables
Readline has variables that can be used to further cus-
tomize 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 audi-
ble, 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
characters it reads), regardless of what the termi-
nal 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 pre-
fix).
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 gener-
ated 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 vari-
able, 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
keymap 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
readline attempts word completion.
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 per-
formed 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 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 termi-
nal-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 portion 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 applica-
tion 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
$endif This command, as you saw in the previous example,
terminates an $if command.
$else Commands in this branch of the $if directive are
executed 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 charac-
ters (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,
moving back in the list.
next-history (C-n)
Fetch the next command from the history list, mov-
ing 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
(usually the second word on the previous line) at
point (the current cursor position). With an argu-
ment n, insert the nth word from the previous com-
mand (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 charac-
ters 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
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.
transpose-chars (C-t)
Drag the character before point forward over the
character at point. Point moves forward as well.
If point is at the end of the line, then transpose
the two characters before point. Negative argu-
ments 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 dif-
ferent 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 accumulat-
ing, or start a new argument. M-- starts a nega-
tive argument.
universal-argument
Each time this is executed, the argument count is
multiplied by four. The argument count is ini-
tially 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 applica-
tion-specific. Bash, for instance, attempts com-
pletion 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 produces a match, filename comple-
tion is attempted. Gdb, on the other hand, allows
completion of program functions and variables, and
only attempts filename completion 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-comple-
tions. By default, this is not bound to a key.
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 save the definition.
call-last-kbd-macro (C-x e)
Re-execute the last keyboard macro defined, by mak-
ing 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 incor-
porate any bindings or variable assignments found
there.
abort (C-g)
Abort the current editing command and ring the ter-
minal'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 equiva-
lent 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
typing 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 argu-
ment 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
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. Charac-
ters 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 remain-
ing characters are unbound, which causes readline to ring
the bell (subject to the setting of the bell-style vari-
able).
