1.2 Readline Interaction

+ + +

Often during an interactive session you type in a long line of text, only to notice that the first word on the line is misspelled. The Readline library gives you a set of commands for manipulating the text as you type it in, allowing you to just fix your typo, and not forcing you to retype the majority of the line. Using these editing commands, you move the cursor to the place that needs correction, and delete or insert the text of the corrections. Then, when you are satisfied with -the line, you simply press RET. You do not have to be at the -end of the line to press RET; the entire line is accepted +the line, you simply press RET.

If the description for a command says that it ‘kills’ text, then you can be sure that you can get the text back in a different (or the same) place later. -

- -When you use a kill command, the text is saved in a kill-ring. +

+

When you use a kill command, the text is saved in a kill-ring. Any number of consecutive kills save all of the killed text together, so that when you yank it back, you get it all. The kill ring is not line specific; the text that you killed on a previously typed line is available to be yanked back later, when you are typing another line. - -

1.2.4 Readline Arguments

+ +

You can pass numeric arguments to Readline commands. Sometimes the +argument acts as a repeat count, other times it is the sign of the argument that is significant. If you pass a negative argument to a command which normally acts in a forward direction, that command will act in a backward direction. For example, to kill text back to the -start of the line, you might type `M-- C-k'. -

- -The general way to pass numeric arguments to a command is to type meta -digits before the command. If the first `digit' typed is a minus -sign (`-'), then the sign of the argument will be negative. Once +start of the line, you might type ‘M-- C-k’. +

+

The general way to pass numeric arguments to a command is to type meta +digits before the command. If the first ‘digit’ typed is a minus +sign (‘-’), then the sign of the argument will be negative. Once you have typed one meta digit to get the argument started, you can type the remainder of the digits, and then the command. For example, to give -the C-d command an argument of 10, you could type `M-1 0 C-d', +the C-d command an argument of 10, you could type ‘M-1 0 C-d’, which will delete the next ten characters on the input line. -

+

Incremental searches begin before the user has finished typing 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. To search backward in the history for a particular string, type -C-r. Typing C-s searches forward through the history. -The characters present in the value of the isearch-terminators variable +C-r. Typing C-s searches forward through the history. +The characters present in the value of the isearch-terminators variable are used to terminate an incremental search. -If that variable has not been assigned a value, the ESC and -C-J characters will terminate an incremental search. -C-g will abort an incremental search and restore the original line. +If that variable has not been assigned a value, the ESC and +C-J characters will terminate an incremental search. +C-g will abort an incremental search and restore the original line.

To find other matching entries in the history list, type C-r or +C-s as appropriate. This will search backward or forward in the history for the next entry matching the search string typed so far.

1.3.2 Conditional Init 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 performed as the result of tests. There are four parser directives used. -

- -

-
$if -
The $if construct allows bindings to be made based on the +

+
+
$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, after any comparison operator, extends to the end of the line; unless otherwise noted, 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. +

+
+
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 terminal-specific +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 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 both 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, +terminal’s function keys. The word on the right side of the +‘=’ is tested against both 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. -

version -
The version test may be used to perform comparisons against +

+
+
version
+

The version test may be used to perform comparisons against specific Readline versions. -The version expands to the current Readline version. +The version expands to the current Readline version. The set of comparison operators includes -`=' (and `=='), `!=', `<=', `>=', `<', -and `>'. +‘=’ (and ‘==’), ‘!=’, ‘<=’, ‘>=’, ‘<’, +and ‘>’. The version number supplied on the right side of the operator consists of a major version number, an optional decimal point, and an optional -minor version (e.g., `7.1'). If the minor version is omitted, it -is assumed to be `0'. -The operator may be separated from the string version and +minor version (e.g., ‘7.1’). If the minor version is omitted, it +is assumed to be ‘0’. +The operator may be separated from the string version and from the version number argument by whitespace. The following example sets a variable if the Readline version being used is 7.0 or newer: -
 
$if version >= 7.0
+

+
$if version >= 7.0
 set show-mode-in-prompt on

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
+

+
$if Bash
 # Quote the current or previous word
-"\C-xq": "\eb\"\ef\""
+"\C-xq": "\eb\"\ef\""
 $endif
-

+

+

The variable construct provides simple equality tests for Readline variables and values. -The permitted comparison operators are `=', `==', and `!='. +The permitted comparison operators are ‘=’, ‘==’, and ‘!=’. The variable name must be separated from the comparison operator by whitespace; the operator may be separated from the value on the right hand side by whitespace. Both string and boolean variables may be tested. Boolean variables must be -tested against the values on and off. -The following example is equivalent to the mode=emacs test described +tested against the values on and off. +The following example is equivalent to the mode=emacs test described above: -
 
$if editing-mode == emacs
+

$if editing-mode == emacs

This command, as seen in the previous example, terminates an +$if command. +

2.2 Custom Functions

Readline provides many functions for manipulating the text of +the line, but it isn’t possible to anticipate the needs of all programs.

+

readline.h defines a C preprocessor variable that should +be treated as an integer, RL_READLINE_VERSION, which may be used to conditionally compile application code depending on the installed Readline version. The value is a hexadecimal encoding of the major and minor version numbers of the library, -of the form 0xMMmm. MM is the two-digit major -version number; mm is the two-digit minor version number. +of the form 0xMMmm. MM is the two-digit major +version number; mm is the two-digit minor version number.

+
+

2.4.1 Naming a Function

+ +

The user can dynamically change the bindings of keys while using Readline. This is done by representing the function with a descriptive name. The user is able to type the descriptive name when referring to the function. Thus, in an init file, one might find -

+

+
+
Meta-Rubout:	backward-kill-word
+
-
 
Meta-Rubout:	backward-kill-word

- -This binds the keystroke Meta-Rubout to the function -descriptively named backward-kill-word. You, as the +

This binds the keystroke Meta-Rubout to the function +descriptively named backward-kill-word. You, as the programmer, should bind the functions you write to descriptive names as well. Readline provides a function for doing that: -

- - -

-
Function: int rl_add_defun (const char *name, rl_command_func_t *function, int key) -
Add name to the list of named functions. Make function be -the function that gets called. If key is not -1, then bind it to -function using rl_bind_key(). -
-

+
+
Function: int rl_add_defun (const char *name, rl_command_func_t *function, int key)
+

Add name to the list of named functions. Make function be +the function that gets called. If key is not -1, then bind it to +function using rl_bind_key(). +

+ +

Using this function alone is sufficient for most applications. It is the recommended way to add a few functions to the default functions that Readline has built in. If you need to do something other than adding a function to Readline, you may need to use the underlying functions described below. -

2.4.2 Selecting a Keymap

There is a class of signals that can be sent to the process currently reading input from the keyboard.

1.2 Readline Interaction

+ + +

Often during an interactive session you type in a long line of text, only to notice that the first word on the line is misspelled. The Readline library gives you a set of commands for manipulating the text as you type it in, allowing you to just fix your typo, and not forcing you to retype the majority of the line. Using these editing commands, you move the cursor to the place that needs correction, and delete or insert the text of the corrections. Then, when you are satisfied with -the line, you simply press RET. You do not have to be at the -end of the line to press RET; the entire line is accepted +the line, you simply press RET.

- -If the description for a command says that it `kills' text, then you can +(‘Cut’ and ‘paste’ are more recent jargon for ‘kill’ and ‘yank’.) +

+

If the description for a command says that it ‘kills’ text, then you can be sure that you can get the text back in a different (or the same) place later. -

- -When you use a kill command, the text is saved in a kill-ring. +

+

When you use a kill command, the text is saved in a kill-ring. Any number of consecutive kills save all of the killed text together, so that when you yank it back, you get it all. The kill ring is not line specific; the text that you killed on a previously typed line is available to be yanked back later, when you are typing another line. - -

- -Here is the list of commands for killing text. -

1.2.4 Readline Arguments

+ +

You can pass numeric arguments to Readline commands. Sometimes the +argument acts as a repeat count, other times it is the sign of the argument that is significant. If you pass a negative argument to a command which normally acts in a forward direction, that command will act in a backward direction. For example, to kill text back to the -start of the line, you might type `M-- C-k'. -

- -The general way to pass numeric arguments to a command is to type meta -digits before the command. If the first `digit' typed is a minus -sign (`-'), then the sign of the argument will be negative. Once +start of the line, you might type ‘M-- C-k’. +

+

The general way to pass numeric arguments to a command is to type meta +digits before the command. If the first ‘digit’ typed is a minus +sign (‘-’), then the sign of the argument will be negative. Once you have typed one meta digit to get the argument started, you can type the remainder of the digits, and then the command. For example, to give -the C-d command an argument of 10, you could type `M-1 0 C-d', +the C-d command an argument of 10, you could type ‘M-1 0 C-d’, which will delete the next ten characters on the input line. -

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 typing the +There are two search modes: incremental and non-incremental. +

+

Incremental searches begin before the user has finished typing 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. To search backward in the history for a particular string, type -C-r. Typing C-s searches forward through the history. -The characters present in the value of the isearch-terminators variable +C-r.

1.3.2 Conditional Init 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 performed as the result of tests. There are four parser directives used. -

- -

-
$if -
The $if construct allows bindings to be made based on the +

+
+
$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, after any comparison operator, extends to the end of the line; unless otherwise noted, 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. +

+
+
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 terminal-specific +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 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 both 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, +terminal’s function keys. The word on the right side of the +‘=’ is tested against both 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. -

version -
The version test may be used to perform comparisons against +

+
+
version
+

The version test may be used to perform comparisons against specific Readline versions. -The version expands to the current Readline version. +The version expands to the current Readline version. The set of comparison operators includes -`=' (and `=='), `!=', `<=', `>=', `<', -and `>'. +‘=’ (and ‘==’), ‘!=’, ‘<=’, ‘>=’, ‘<’, +and ‘>’. The version number supplied on the right side of the operator consists of a major version number, an optional decimal point, and an optional -minor version (e.g., `7.1'). If the minor version is omitted, it -is assumed to be `0'. -The operator may be separated from the string version and +minor version (e.g., ‘7.1’). If the minor version is omitted, it +is assumed to be ‘0’. +The operator may be separated from the string version and from the version number argument by whitespace. The following example sets a variable if the Readline version being used is 7.0 or newer: -
 
$if version >= 7.0
+

+
$if version >= 7.0
 set show-mode-in-prompt on

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

+
$if Bash
 # Quote the current or previous word
-"\C-xq": "\eb\"\ef\""
+"\C-xq": "\eb\"\ef\""

+

The variable construct provides simple equality tests for Readline variables and values. -The permitted comparison operators are `=', `==', and `!='. +The permitted comparison operators are ‘=’, ‘==’, and ‘!=’. The variable name must be separated from the comparison operator by whitespace; the operator may be separated from the value on the right hand side by whitespace. Both string and boolean variables may be tested. Boolean variables must be -tested against the values on and off. -The following example is equivalent to the mode=emacs test described +tested against the values on and off. +The following example is equivalent to the mode=emacs test described above: -
 
$if editing-mode == emacs

$if editing-mode == emacs
 set show-mode-in-prompt on

This command, as seen in the previous example, terminates an +$if command. +

1.4.3 Commands For Changing Text

+ +
+
end-of-file (usually C-d)
+

The character indicating end-of-file as set, for example, by +stty. If this character is read when there are no characters on the line, and point is at the beginning of the line, Readline -interprets it as the end of input and returns EOF. -

+

Insert yourself. +

+
+
bracketed-paste-begin ()
+

This function is intended to be bound to the "bracketed paste" escape sequence sent by some terminals, and such a binding is assigned by default. It allows Readline to insert the pasted text as a single unit without treating each character as if it had been read from the keyboard. The characters -are inserted as if each one was bound to self-insert instead of +are inserted as if each one was bound to self-insert instead of executing any editing commands. -
