NAME
readline - get a line from a user with editing
SYNOPSIS
#include <stdio.h>
#include <readline.h>
#include <history.h>
char *readline (prompt)
char *prompt;
COPYRIGHT
Readline is Copyright (C) 1989, 1991, 1993, 1995, 1996 by
the Free Software Foundation, Inc.
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.
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.
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 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. 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 begin-
ning with a # are comments. Lines beginning with a $ indi-
cate conditional constructs. Other lines denote key bind-
ings 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 com-
mand 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 Control- pre-
fixes, 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 GNU Emacs style escape
sequences is
\C- control prefix
\M- meta prefix
\e an escape character
\\ backslash
" \" literal "
\' literal '
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 character whose ASCII code is the octal value
nnn (one to three digits)
\xnnn
the character whose ASCII code is the hexadecimal
value nnn (one to three digits)
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. In the macro body,
the backslash escapes described above are expanded.
Backslash will quote any other 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:
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
insert-comment command is executed. This command is
bound to M-# in emacs mode and to # in vi command mode.
completion-ignore-case (Off)
If set to On, readline performs filename matching and
completion in a case-insensitive fashion.
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.
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).
disable-completion (Off)
If set to On, readline will inhibit word completion.
Completion characters will be inserted into the line as
if they had been mapped to self-insert.
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.
enable-keypad (Off)
When set to On, readline will try to enable the appli-
cation keypad when it is called. Some systems need
this to enable the arrow keys.
expand-tilde (Off)
If set to on, tilde expansion is performed when read-
line attempts word completion.
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.
input-meta (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. The name meta-flag is a synonym
for this variable.
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 will ter-
minate an incremental search.
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.
mark-directories (On)
If set to On, complete<d directory names have a slash
appended.
mark-modified-lines (Off)
If set to On, history lines that have been modified are
displayed with a preceding asterisk (*).
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.
print-completions-horizontally (Off)
If set to On, readline will display completions with
matches sorted horizontally in alphabetical order,
rather than down the screen.
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.
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 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 four 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 seen 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.
$include
This directive takes a single filename as an argument
and reads commands and 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 typ-
ing 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. The characters present in the
value of the isearch-terminators variable are used to ter-
minate an incremental search. If that variable has not been
assigned a value the Escape and Control-J characters will
terminate an incremental search. Control-G will abort an
incremental search and restore 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 Control-S or
Control-R as appropriate. This will search backward or for-
ward in the history for the next line matching the search
string typed so far. Any other key sequence bound to a
readline command will terminate the search and execute that
command. For instance, a newline will terminate the search
and accept the line, thereby executing the command from the
history list.
Non-incremental searches read the entire search string
before starting to search for matching history lines. 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.
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 the current or 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.
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 cursor position (the point). This is a
non-incremental search.
history-search-backward
Search backward through the history for the string of
characters between the start of the current line and
the point. This is a non-incremental search.
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 of the previous history entry). With an
argument, behave exactly like yank-nth-arg. Successive
calls to yank-last-arg move back through the history
list, inserting the last argument of each line in turn.
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 bound to
Bdelete-char, 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.
forward-backward-delete-char
Delete the character under the cursor, unless the cur-
sor is at the end of the line, in which case the char-
acter behind the cursor is deleted. By default, this
is not bound to a key.
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
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 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, 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.
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.
The killed text is saved on the kill-ring.
kill-whole-line
Kill all characters on the current line, no matter
where the cursor is.
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 (M-\)
Delete all spaces and tabs around point.
kill-region
Kill the text between the point and mark (saved cursor
position). This text is referred to as the region.
copy-region-as-kill
Copy the text in the region to the kill buffer.
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 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
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, exe-
cuting universal-argument again ends the numeric argu-
ment, but is otherwise ignored. As a special case, if
this command is immediately followed by a character
that is neither a digit or 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 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 (M-*)
Insert all completions of the text before point that
would have been generated by possible-completions.
menu-complete
Similar to complete, but replaces the word to be com-
pleted with a single match from the list of possible
completions. Repeated execution of menu-complete steps
through the list of possible completions, inserting
each match in turn. At the end of the list of comple-
tions, the bell is rung and the original text is
restored. An argument of n moves n positions forward
in the list of matches; a negative argument may be used
to move backward through the list. This command is
intended to be bound to TAB, but 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). If at
the end of the line, 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 key-
board macro.
end-kbd-macro (C-x ))
Stop saving the characters typed into the current key-
board 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.
Miscellaneous
re-read-init-file (C-x C-r)
Read in the contents of the inputrc file, and incor-
porate 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, M-x, ...)
If the metafied character x is lowercase, run the com-
mand that is bound to the corresponding uppercase char-
acter.
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 exe-
cuting 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 current point. If a numeric argu-
ment is supplied, the mark is set to that position.
exchange-point-and-mark (C-x C-x)
Swap the point with the mark. The current cursor posi-
tion is set to the saved position, and the old cursor
position is saved as the mark.
character-search (C-])
A character is read and point is moved to the next
occurrence of that character. A negative count
searches for previous occurrences.
character-search-backward (M-C-])
A character is read and point is moved to the previous
occurrence of that character. A negative count
searches for subsequent occurrences.
insert-comment (M-#)
The value of the readline comment-begin variable is
inserted at the beginning of the current line, and the
line is accepted as if a newline had been typed. This
makes the current line a shell comment.
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 ouput. 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).
