readline - get a line from a user with editing
#include <stdio.h>#include <readline/readline.h>#include <readline/history.h>
readline (const char *prompt);
Readline is Copyright (C) 1989-2001 by the Free Software Foundation, Inc.
readlinewill read a line from the terminaland return it, usingpromptas a prompt. If promptis NULL or the empty string, no prompt is issued.The line returned is allocated withmalloc(3);the caller must free it when finished. The line returnedhas the final newline removed, so only the text of the lineremains.
readlineoffers editing capabilities while the user is entering theline.By default, the line editing commandsare similar to those of emacs.A vi-style line editing interface is also available.
This manual page describes only the most basic use of readline.Much more functionality is available; seeThe GNU Readline Library and The GNU History Libraryfor additional information.
readlinereturns the text of the line read. A blank linereturns the empty string. IfEOFis encountered while reading a line, and the line is empty,NULLis returned. If anEOFis read with a non-empty line, it istreated as a newline.
An emacs-style notation is used to denotekeystrokes. Control keys are denoted by C-key, e.g., C-nmeans Control-N. Similarly, metakeys are denoted by M-key, so M-x means Meta-X. (On keyboardswithout a metakey, M-x means ESC x, i.e., press the Escape keythen thexkey. This makes ESC the meta prefix.The combination M-C-x means ESC-Control-x,or press the Escape keythen hold the Control key while pressing thexkey.)
Readline commands may be given numericarguments,which normally act as a repeat count. Sometimes, however, it is thesign of the argument that is significant. Passing a negative argumentto a command that acts in the forward direction (e.g., kill-line)causes that command to act in a backward direction. Commands whosebehavior with arguments deviates from this are noted.
When a command is described as killing text, the textdeleted is saved for possible future retrieval(yanking). The killed text is saved in akill ring. Consecutive kills cause the text to beaccumulated into one unit, which can be yanked all at once. Commands which do not kill text separate the chunks of texton the kill ring.
Readline is customized by putting commands in an initializationfile (the inputrc file).The name of this file is taken from the value of theINPUTRCenvironment variable. If that variable is unset, the default is~/.inputrc.When a program which uses the readline library starts up, theinit file is read, and the key bindings and variables are set.There are only a few basic constructs allowed in thereadline 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 commandsand bindings.
For example, placing
- C-Meta-u: universal-argument
into the inputrcwould make M-C-u execute the readline commanduniversal-argument.
The following symbolic character names are recognized whileprocessing key bindings:DEL,ESC,ESCAPE,LFD,NEWLINE,RET,RETURN,RUBOUT,SPACE,SPC,andTAB.
In addition to command names, readline allows keys to be boundto a string that is inserted when the key is pressed (a macro).
The syntax for controlling key bindings in theinputrcfile is simple. All that is required is the name of thecommand or the text of a macro and a key sequence to whichit 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,keynameis the name of a key spelled out in English. For example:
- Control-u: universal-argument
Control-o: "> output"
In the above example,C-uis bound to the functionuniversal-argument,M-DELis bound to the functionbackward-kill-word,andC-ois bound to run the macroexpressed on the right hand side (that is, to insert the text``> output''into the line).
In the second form, "keyseq":function-name or macro,keyseqdiffers fromkeynameabove in that strings denotingan entire key sequence may be specified by placing the sequencewithin double quotes. Some GNU Emacs style key escapes can beused, as in the following example, but the symbolic character namesare not recognized.
- "\C-u": universal-argument
"\e[11~": "Function Key 1"
In this example,C-uis again bound to the functionuniversal-argument.C-x C-ris bound to the functionre-read-init-file,and ESC [ 1 1 ~is bound to insert the text``Function Key 1''.
The full set of GNU Emacs style escape sequences available when specifyingkey sequences is
- control prefix
- meta prefix
- an escape character
- literal ", a double quote
- literal ', a single quote
In addition to the GNU Emacs style escape sequences, a secondset of backslash escapes is available:
- alert (bell)
- form feed
- carriage return
- horizontal tab
- vertical tab
- the eight-bit character whose value is the octal value nnn(one to three digits)
- the eight-bit character whose value is the hexadecimal value HH(one or two hex digits)
When entering the text of a macro, single or double quotes shouldbe used to indicate a macro definition. Unquoted textis 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 '.
Bashallows the current readline key bindings to be displayed or modifiedwith thebindbuiltin command. The editing mode may be switched during interactiveuse by using the-ooption to thesetbuiltin command. Other programs using this library providesimilar mechanisms. Theinputrcfile may be edited and re-read if a program does not provideany other means to incorporate new bindings.
Readline has variables that can be used to further customize itsbehavior. A variable may be set in theinputrcfile with a statement of the form
set variable-name value
Except where noted, readline variables can take the valuesOnorOff(without regard to case).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 tovisible, 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 theinsert-commentcommand is executed.This command is bound toM-#in emacs mode and to#in vi command mode.
- completion-ignore-case (Off)
- If set to On, readline performs filename matching and completionin a case-insensitive fashion.
- completion-query-items (100)
- This determines when the user is queried about viewingthe number of possible completionsgenerated by the possible-completions command.It may be set to any integer value greater than or equal tozero. If the number of possible completions is greater thanor equal to the value of this variable, the user is asked whetheror not he wishes to view them; otherwise they are simply listedon the terminal.
- convert-meta (On)
- If set to On, readline will convert characters with theeighth bit set to an ASCII key sequenceby stripping the eighth bit and prefixing it with anescape 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 beenmapped to self-insert.
- editing-mode (emacs)
- Controls whether readline begins with a set of key bindings similarto emacs or vi.editing-modecan be set to eitheremacsorvi.
- enable-keypad (Off)
- When set to On, readline will try to enable the applicationkeypad when it is called. Some systems need this to enable thearrow keys.
- expand-tilde (Off)
- If set to on, tilde expansion is performed when readlineattempts word completion.
- If set to on, the history code attempts to place point at the same location on each history line retrived with previous-history or next-history.
- 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 itbecomes 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 clear the eighth bit in the characters it reads),regardless of what the terminal claims it can support. The namemeta-flagis a synonym for this variable.
- isearch-terminators (``C-[ C-J'')
- The string of characters that should terminate an incrementalsearch without subsequently executing the character as a command.If this variable has not been given a value, the charactersESC and C-J will terminate an incremental search.
- keymap (emacs)
- Set the current readline keymap. The set of legal keymap names isemacs, emacs-standard, emacs-meta, emacs-ctlx, vi, vi-move,vi-command, andvi-insert.vi is equivalent to vi-command; emacs isequivalent to emacs-standard. The default value isemacs.The value ofediting-modealso affects the default keymap.
- mark-directories (On)
- If set to On, completed directory names have a slashappended.
- mark-modified-lines (Off)
- If set to On, history lines that have been modified are displayedwith a preceding asterisk (*).
- match-hidden-files (On)
- This variable, when set to On, causes readline to match files whose names begin with a `.' (hidden files) when performing filename completion, unless the leading `.' is supplied by the user in the filename to be completed.
- output-meta (Off)
- If set to On, readline will display characters with theeighth bit set directly rather than as a meta-prefixed escapesequence.
- print-completions-horizontally (Off)
- If set to On, readline will display completions with matchessorted horizontally in alphabetical order, rather than down the screen.
- show-all-if-ambiguous (Off)
- This alters the default behavior of the completion functions. Ifset toon,words which have more than one possible completion cause thematches 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 possiblecompletions.
Readline implements a facility similar in spirit to the conditionalcompilation features of the C preprocessor which allows keybindings and variable settings to be performed as the resultof tests. There are four parser directives used.
- The $ifconstruct allows bindings to be made based on theediting mode, the terminal being used, or the application usingreadline. The text of the test extends to the end of the line;no characters are required to isolate it.
- The mode= form of the $if directive is used to testwhether readline is in emacs or vi mode.This may be used in conjunctionwith the set keymap command, for instance, to set bindings inthe emacs-standard and emacs-ctlx keymaps only ifreadline is starting out in emacs mode.
- The term= form may be used to include terminal-specifickey bindings, perhaps to bind the key sequences output by theterminal's function keys. The word on the right side of the=is tested against the full name of the terminal and the portionof the terminal name before the first -. This allowssunto match bothsunandsun-cmd,for instance.
- The application construct is used to includeapplication-specific settings. Each program using the readlinelibrary sets the application name, and an initializationfile can test for a particular value.This could be used to bind key sequences to functions useful fora specific program. For instance, the following command adds akey sequence that quotes the current or previous word in Bash:
$if Bash# Quote the current or previous word"\C-xq": "\eb\"\ef\""$endif
- This command, as seen in the previous example, terminates an$if command.
- Commands in this branch of the $if directive are executed ifthe test fails.
- This directive takes a single filename as an argument and reads commandsand bindings from that file. For example, the following directivewould read /etc/inputrc:
Readline provides commands for searching through the command historyfor lines containing a specified string.There are two search modes:incrementalandnon-incremental.
Incremental searches begin before the user has finished typing thesearch string.As each character of the search string is typed, readline displaysthe next entry from the history matching the string typed so far.An incremental search requires only as many characters as needed tofind the desired history entry.To search backward in the history for a particular string, typeC-r. Typing C-s searches forward through the history.The characters present in the value of the isearch-terminatorsvariable are used to terminate an incremental search.If that variable has not been assigned a value the Escape andC-J characters will terminate an incremental search.C-G will abort an incremental search and restore the originalline.When the search is terminated, the history entry containing thesearch string becomes the current line.
To find other matching entries in the history list, type C-s orC-r as appropriate.This will search backward or forward in the history for the nextline matching the search string typed so far.Any other key sequence bound to a readline command will terminatethe search and execute that command.For instance, a newline will terminate the search and acceptthe line, thereby executing the command from the history list.A movement command will terminate the search, make the last line foundthe current line, and begin editing.
Non-incremental searches read the entire search string before startingto search for matching history lines. The search string may betyped by the user or be part of the contents of the current line.
The following is a list of the names of the commands and the defaultkey sequences to which they are bound.Command names without an accompanying key sequence are unbound by default.
In the following descriptions, point refers to the current cursorposition, and mark refers to a cursor position saved by theset-mark command.The text between the point and mark is referred to as the region.
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)

- forward-word (M-f)
- Move forward to the end of the next word. Words are composed ofalphanumeric characters (letters and digits).
- backward-word (M-b)
- Move back to the start of the current or previous word. Words arecomposed 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 thescreen.
- 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 isnon-empty, it may be added to the history list for future recall withadd_history().If the line is a modified history line, the history line is restored to its original state.
- previous-history (C-p)
- Fetch the previous command from the history list, moving back inthe list.
- next-history (C-n)
- Fetch the next command from the history list, moving forward in thelist.
- 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 beingentered.
- reverse-search-history (C-r)
- Search backward starting at the current line and moving `up' throughthe history as necessary. This is an incremental search.
- forward-search-history (C-s)
- Search forward starting at the current line and moving `down' throughthe history as necessary. This is an incremental search.
- non-incremental-reverse-search-history (M-p)
- Search backward through the history starting at the current lineusing 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 searchfor a string supplied by the user.
- Search forward through the history for the string of charactersbetween the start of the current line and the current cursorposition (the point).This is a non-incremental search.
- Search backward through the history for the string of charactersbetween 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 (usuallythe second word on the previous line) at point.With an argumentn,insert the nth word from the previous command (the wordsin the previous command begin with word 0). A negative argumentinserts 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 ofthe previous history entry). With an argument,behave exactly like yank-nth-arg.Successive calls to yank-last-arg move back through the historylist, inserting the last argument of each line in turn.
Commands for Changing Text
- delete-char (C-d)
- Delete the character at point. If point is at thebeginning of the line, there are no characters in the line, andthe last character typed was not bound to delete-char, then returnEOF.
- backward-delete-char (Rubout)
- Delete the character behind the cursor. When given a numeric argument,save the deleted text on the kill ring.
- Delete the character under the cursor, unless the cursor is at theend of the line, in which case the character behind the cursor isdeleted.
- quoted-insert (C-q, C-v)
- Add the next character that you type to the line verbatim. This ishow 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,moving point forward as well.If point is at the end of the line, then this transposesthe two characters before point.Negative arguments have no effect.
- transpose-words (M-t)
- Drag the word before point past the word after point,moving point over that word as well.If point is at the end of the line, this transposesthe last two words on the line.
- upcase-word (M-u)
- Uppercase the current (or following) word. With a negative argument,uppercase the previous word, but do not move point.
- downcase-word (M-l)
- Lowercase the current (or following) word. With a negative argument,lowercase the previous word, but do not move point.
- capitalize-word (M-c)
- Capitalize the current (or following) word. With a negative argument,capitalize the previous word, but do not move point.
Killing and Yanking
- kill-line (C-k)
- Kill the text from point 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 all characters on the current line, no matter where point is.
- kill-word (M-d)
- Kill from point the end of the current word, or if betweenwords, to the end of the next word. Word boundaries are the same asthose used by forward-word.
- backward-kill-word (M-Rubout)
- Kill the word behind point.Word boundaries are the same as those used by backward-word.
- unix-word-rubout (C-w)
- Kill the word behind point, using white space as a word boundary.The killed text is saved on the kill-ring.
- delete-horizontal-space (M-\)
- Delete all spaces and tabs around point.
- Kill the text between the point and mark (saved cursor position).This text is referred to as the region.
- Copy the text in the region to the kill buffer.
- Copy the word before point to the kill buffer.The word boundaries are the same as backward-word.
- Copy the word following point to the kill buffer.The word boundaries are the same as forward-word.
- yank (C-y)
- Yank the top of the kill ring into the buffer at point.
- yank-pop (M-y)
- Rotate the kill ring, and yank the new top. Only works followingyankoryank-pop.
- digit-argument (M-0, M-1, ..., M--)
- Add this digit to the argument already accumulating, or start a newargument. M-- starts a negative argument.
- This is another way to specify an argument.If this command is followed by one or more digits, optionally with aleading minus sign, those digits define the argument.If the command is followed by digits, executinguniversal-argumentagain ends the numeric argument, but is otherwise ignored.As a special case, if this command is immediately followed by acharacter that is neither a digit or minus sign, the argument countfor the next command is multiplied by four.The argument count is initially one, so executing this function thefirst time makes the argument count four, a second time makes theargument count sixteen, and so on.
- 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 @), orcommand (including aliases and functions) in turn. If noneof these produces a match, filename completion is attempted.Gdb,on the other hand,allows completion of program functions and variables, andonly attempts filename completion 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 pointthat would have been generated bypossible-completions.
- Similar to complete, but replaces the word to be completedwith a single match from the list of possible completions.Repeated execution of menu-complete steps through the listof possible completions, inserting each match in turn.At the end of the list of completions, the bell is rung(subject to the setting of Bbell-style)and the original text is restored.An argument of n moves n positions forward in the listof matches; a negative argument may be used to move backward through the list.This command is intended to be bound to TAB, but is unboundby default.
- Deletes the character under the cursor if not at the beginning orend of the line (like delete-char).If at the end of the line, behaves identically topossible-completions.
- 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 macroand store the definition.
- call-last-kbd-macro (C-x e)
- Re-execute the last keyboard macro defined, by making the charactersin the macro appear as if typed at the keyboard.
- re-read-init-file (C-x C-r)
- Read in the contents of the inputrc file, and incorporateany bindings or variable assignments found there.
- abort (C-g)
- Abort the current editing command andring the terminal's bell (subject to the setting ofbell-style).
- do-uppercase-version (M-a, M-b, M-x, ...)
- If the metafied character x is lowercase, run the commandthat is bound to the corresponding uppercase character.
- prefix-meta (ESC)
- Metafy the next character typed.ESCfis equivalent toMeta-f.
- undo (C-_, C-x C-u)
- Incremental undo, separately remembered for each line.
- revert-line (M-r)
- Undo all changes made to this line. This is like executing theundocommand enough times to return the line to its initial state.
- tilde-expand (M-&)
- Perform tilde expansion on the current word.
- set-mark (C-@, M-<space>)
- Set the mark to the point. If anumeric argument 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 position is set tothe 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 thatcharacter. 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 thatcharacter. A negative count searches for subsequent occurrences.
- insert-comment (M-#)
- The value of the readlinecomment-beginvariable is inserted at the beginning of the current line, and the lineis accepted as if a newline had been typed. The default value ofcomment-beginmakes the current line a shell comment.
- Print all of the functions and their key bindings to thereadline output stream. If a numeric argument is supplied,the output is formatted in such a way that it can be made partof an inputrc file.
- Print all of the settable variables and their values to thereadline output stream. If a numeric argument is supplied,the output is formatted in such a way that it can be made partof an inputrc file.
- Print all of the readline key sequences bound to macros and thestrings they ouput. If a numeric argument is supplied,the output is formatted in such a way that it can be made partof an inputrc file.
- emacs-editing-mode (C-e)
- When inviediting mode, this causes a switch toemacsediting mode.
- vi-editing-mode (M-C-j)
- When inemacsediting mode, this causes a switch toviediting mode.
DEFAULT KEY BINDINGS
The following is a list of the default emacs and vi bindings.Characters with the eighth bit set are written as M-<character>, andare referred to asmetafiedcharacters.The printable ASCII characters not mentioned in the list of emacsstandard bindings are bound to theself-insertfunction, which just inserts the given character into the input line.In vi insertion mode, all characters not specifically mentioned arebound toself-insert.Characters assigned to signal generation bystty(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 inthe emacs mode meta keymap.The remaining characters are unbound, which causes readlineto ring the bell (subject to the setting of thebell-stylevariable).
