| <!--docid::SEC2::--> |
| <P> |
| |
| The following paragraphs describe the notation used to represent |
| keystrokes. |
| </P><P> |
| |
| The text <KBD>C-k</KBD> is read as `Control-K' and describes the character |
| produced when the <KBD>k</KBD> key is pressed while the Control key |
| is depressed. |
| </P><P> |
| |
| The text <KBD>M-k</KBD> is read as `Meta-K' and describes the character |
| produced when the Meta key (if you have one) is depressed, and the <KBD>k</KBD> |
| key is pressed. |
| The Meta key is labeled <KBD>ALT</KBD> on many keyboards. |
| On keyboards with two keys labeled <KBD>ALT</KBD> (usually to either side of |
| the space bar), the <KBD>ALT</KBD> on the left side is generally set to |
| work as a Meta key. |
| The <KBD>ALT</KBD> key on the right may also be configured to work as a |
| Meta key or may be configured as some other modifier, such as a |
| Compose key for typing accented characters. |
| </P><P> |
| |
| If you do not have a Meta or <KBD>ALT</KBD> key, or another key working as |
| a Meta key, the identical keystroke can be generated by typing <KBD>ESC</KBD> |
| <EM>first</EM>, and then typing <KBD>k</KBD>. |
| Either process is known as <EM>metafying</EM> the <KBD>k</KBD> key. |
| </P><P> |
| |
| The text <KBD>M-C-k</KBD> is read as `Meta-Control-k' and describes the |
| character produced by <EM>metafying</EM> <KBD>C-k</KBD>. |
| </P><P> |
| |
| In addition, several keys have their own names. Specifically, |
| <KBD>DEL</KBD>, <KBD>ESC</KBD>, <KBD>LFD</KBD>, <KBD>SPC</KBD>, <KBD>RET</KBD>, and <KBD>TAB</KBD> all |
| stand for themselves when seen in this text, or in an init file |
| (see section <A HREF="rluserman.html#SEC9">1.3 Readline Init File</A>). |
| If your keyboard lacks a <KBD>LFD</KBD> key, typing <KBD>C-j</KBD> will |
| produce the desired character. |
| The <KBD>RET</KBD> key may be labeled <KBD>Return</KBD> or <KBD>Enter</KBD> on |
| some keyboards. |

| <!--docid::SEC3::--> |
| <P> |
| |
| 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 <KBD>RET</KBD>. You do not have to be at the |
| end of the line to press <KBD>RET</KBD>; the entire line is accepted |
| regardless of the location of the cursor within the line. |

| In order to enter characters into the line, simply type them. The typed |
| character appears where the cursor was, and then the cursor moves one |
| space to the right. If you mistype a character, you can use your |
| erase character to back up and delete the mistyped character. |
| </P><P> |
| |
| Sometimes you may mistype a character, and |
| not notice the error until you have typed several other characters. In |
| that case, you can type <KBD>C-b</KBD> to move the cursor to the left, and then |
| correct your mistake. Afterwards, you can move the cursor to the right |
| with <KBD>C-f</KBD>. |
| </P><P> |
| |
| When you add text in the middle of a line, you will notice that characters |
| to the right of the cursor are `pushed over' to make room for the text |
| that you have inserted. Likewise, when you delete text behind the cursor, |
| characters to the right of the cursor are `pulled back' to fill in the |
| blank space created by the removal of the text. A list of the bare |
| essentials for editing the text of an input line follows. |
| </P><P> |
| |
| <DL COMPACT> |
| <DT><KBD>C-b</KBD> |
| <DD>Move back one character. |
| <DT><KBD>C-f</KBD> |

| </DL> |
| <P> |
| |
| (Depending on your configuration, the <KBD>Backspace</KBD> key be set to |
| delete the character to the left of the cursor and the <KBD>DEL</KBD> key set |
| to delete the character underneath the cursor, like <KBD>C-d</KBD>, rather |

| <!--docid::SEC5::--> |
| <P> |
| |
| The above table describes the most basic keystrokes that you need |
| in order to do editing of the input line. For your convenience, many |
| other commands have been added in addition to <KBD>C-b</KBD>, <KBD>C-f</KBD>, |
| <KBD>C-d</KBD>, and <KBD>DEL</KBD>. Here are some commands for moving more rapidly |
| about the line. |
| </P><P> |
| |
| <DL COMPACT> |
| <DT><KBD>C-a</KBD> |
| <DD>Move to the start of the line. |
| <DT><KBD>C-e</KBD> |
| <DD>Move to the end of the line. |
| <DT><KBD>M-f</KBD> |
| <DD>Move forward a word, where a word is composed of letters and digits. |
| <DT><KBD>M-b</KBD> |
| <DD>Move backward a word. |
| <DT><KBD>C-l</KBD> |
| <DD>Clear the screen, reprinting the current line at the top. |
| </DL> |
| <P> |
| |
| Notice how <KBD>C-f</KBD> moves forward a character, while <KBD>M-f</KBD> moves |
| forward a word. It is a loose convention that control keystrokes |
| operate on characters while meta keystrokes operate on words. |

| <EM>Killing</EM> text means to delete the text from the line, but to save |
| it away for later use, usually by <EM>yanking</EM> (re-inserting) |
| it back into the line. |
| (`Cut' and `paste' are more recent jargon for `kill' and `yank'.) |
| </P><P> |
| |
| 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. |
| </P><P> |
| |
| When you use a kill command, the text is saved in a <EM>kill-ring</EM>. |
| 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. |
| <A NAME="IDX3"></A> |
| </P><P> |
| |
| Here is the list of commands for killing text. |
| </P><P> |
| |
| <DL COMPACT> |
| <DT><KBD>C-k</KBD> |
| <DD>Kill the text from the current cursor position to the end of the line. |
| <P> |
| |
| <DT><KBD>M-d</KBD> |
| <DD>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 <KBD>M-f</KBD>. |
| <P> |
| |
| <DT><KBD>M-<KBD>DEL</KBD></KBD> |
| <DD>Kill from the cursor the start of the current word, or, if between |
| words, to the start of the previous word. |
| Word boundaries are the same as those used by <KBD>M-b</KBD>. |
| <P> |
| |
| <DT><KBD>C-w</KBD> |
| <DD>Kill from the cursor to the previous whitespace. This is different than |
| <KBD>M-<KBD>DEL</KBD></KBD> because the word boundaries differ. |
| <P> |
| |
| </DL> |
| <P> |
| |
| Here is how to <EM>yank</EM> the text back into the line. Yanking |

| <H3> 1.2.4 Readline Arguments </H3> |
| <!--docid::SEC7::--> |
| <P> |
| |
| You can pass numeric arguments to Readline commands. Sometimes the |
| argument acts as a repeat count, other times it is the <I>sign</I> 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 <SAMP>`M-- C-k'</SAMP>. |
| </P><P> |
| |
| 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 (<SAMP>`-'</SAMP>), 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 <KBD>C-d</KBD> command an argument of 10, you could type <SAMP>`M-1 0 C-d'</SAMP>, |
| which will delete the next ten characters on the input line. |

| <H3> 1.2.5 Searching for Commands in the History </H3> |
| <!--docid::SEC8::--> |
| <P> |
| |
| Readline provides commands for searching through the command history |
| for lines containing a specified string. |
| There are two search modes: <EM>incremental</EM> and <EM>non-incremental</EM>. |
| </P><P> |
| |
| 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 |
| <KBD>C-r</KBD>. Typing <KBD>C-s</KBD> searches forward through the history. |
| The characters present in the value of the <CODE>isearch-terminators</CODE> variable |
| are used to terminate an incremental search. |
| If that variable has not been assigned a value, the <KBD>ESC</KBD> and |
| <KBD>C-J</KBD> characters will terminate an incremental search. |
| <KBD>C-g</KBD> 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. |
| </P><P> |
| |
| To find other matching entries in the history list, type <KBD>C-r</KBD> or |
| <KBD>C-s</KBD> as appropriate. |
| This will search backward or forward in the history for the next |
| entry 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 <KBD>RET</KBD> will terminate the search and accept |
| the line, thereby executing the command from the history list. |
| A movement command will terminate the search, make the last line found |
| the current line, and begin editing. |
| </P><P> |
| |
| Readline remembers the last incremental search string. If two |
| <KBD>C-r</KBD>s are typed without any intervening characters defining a new |
| search string, any remembered search string is used. |
| </P><P> |
| |
| 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. |

| <H2> 1.3 Readline Init File </H2> |
| <!--docid::SEC9::--> |
| <P> |
| |
| Although the Readline library comes with a set of Emacs-like |
| keybindings installed by default, it is possible to use a different set |
| of keybindings. |
| Any user can customize programs that use Readline by putting |
| commands in an <EM>inputrc</EM> file, conventionally in his home directory. |
| The name of this |
| file is taken from the value of the environment variable <CODE>INPUTRC</CODE>. If |
| that variable is unset, the default is <TT>`~/.inputrc'</TT>. |
| </P><P> |
| |
| When a program which uses the Readline library starts up, the |
| init file is read, and the key bindings are set. |
| </P><P> |
| |
| In addition, the <CODE>C-x C-r</CODE> command re-reads this init file, thus |
| incorporating any changes that you might have made to it. |

| <H3> 1.3.1 Readline Init File Syntax </H3> |
| <!--docid::SEC10::--> |
| <P> |
| |
| There are only a few basic constructs allowed in the |
| Readline init file. Blank lines are ignored. |
| Lines beginning with a <SAMP>`#'</SAMP> are comments. |
| Lines beginning with a <SAMP>`$'</SAMP> indicate conditional |
| constructs (see section <A HREF="rluserman.html#SEC11">1.3.2 Conditional Init Constructs</A>). Other lines |
| denote variable settings and key bindings. |
| </P><P> |
| |
| <DL COMPACT> |
| <DT>Variable Settings |
| <DD>You can modify the run-time behavior of Readline by |
| altering the values of variables in Readline |
| using the <CODE>set</CODE> command within the init file. |
| The syntax is simple: |
| <P> |
| |
| <TABLE><tr><td> </td><td class=example><pre>set <VAR>variable</VAR> <VAR>value</VAR> |
| </pre></td></tr></table></P><P> |
| |
| Here, for example, is how to |
| change from the default Emacs-like key binding to use |
| <CODE>vi</CODE> line editing commands: |
| </P><P> |
| |
| <TABLE><tr><td> </td><td class=example><pre>set editing-mode vi |
| </pre></td></tr></table></P><P> |
| |
| Variable names and values, where appropriate, are recognized without regard |
| to case. Unrecognized variable names are ignored. |
| </P><P> |
| |
| Boolean variables (those that can be set to on or off) are set to on if |
| the value is null or empty, <VAR>on</VAR> (case-insensitive), or 1. Any other |
| value results in the variable being set to off. |
| </P><P> |
| |
| A great deal of run-time behavior is changeable with the following |
| variables. |
| </P><P> |
| |
| <A NAME="IDX4"></A> |
| <DL COMPACT> |
| |
| <DT><CODE>bell-style</CODE> |
| <DD><A NAME="IDX5"></A> |
| Controls what happens when Readline wants to ring the terminal bell. |
| If set to <SAMP>`none'</SAMP>, Readline never rings the bell. If set to |
| <SAMP>`visible'</SAMP>, Readline uses a visible bell if one is available. |
| If set to <SAMP>`audible'</SAMP> (the default), Readline attempts to ring |
| the terminal's bell. |
| <P> |
| |
| <DT><CODE>bind-tty-special-chars</CODE> |
| <DD><A NAME="IDX6"></A> |
| If set to <SAMP>`on'</SAMP>, Readline attempts to bind the control characters |
| treated specially by the kernel's terminal driver to their Readline |
| equivalents. |
| <P> |
| |
| <DT><CODE>comment-begin</CODE> |
| <DD><A NAME="IDX7"></A> |
| The string to insert at the beginning of the line when the |
| <CODE>insert-comment</CODE> command is executed. The default value |
| is <CODE>"#"</CODE>. |
| <P> |
| |
| <DT><CODE>completion-ignore-case</CODE> |
| <DD>If set to <SAMP>`on'</SAMP>, Readline performs filename matching and completion |
| in a case-insensitive fashion. |
| The default value is <SAMP>`off'</SAMP>. |
| <P> |
| |
| <DT><CODE>completion-query-items</CODE> |
| <DD><A NAME="IDX8"></A> |
| The number of possible completions that determines when the user is |
| asked whether the list of possibilities should be displayed. |
| If the number of possible completions is greater than this value, |
| Readline will ask the user whether or not he wishes to view |
| them; otherwise, they are simply listed. |
| This variable must be set to an integer value greater than or equal to 0. |
| A negative value means Readline should never ask. |
| The default limit is <CODE>100</CODE>. |
| <P> |
| |
| <DT><CODE>convert-meta</CODE> |
| <DD><A NAME="IDX9"></A> |
| If set to <SAMP>`on'</SAMP>, Readline will convert characters with the |
| eighth bit set to an ASCII key sequence by stripping the eighth |
| bit and prefixing an <KBD>ESC</KBD> character, converting them to a |
| meta-prefixed key sequence. The default value is <SAMP>`on'</SAMP>. |
| <P> |
| |
| <DT><CODE>disable-completion</CODE> |
| <DD><A NAME="IDX10"></A> |
| If set to <SAMP>`On'</SAMP>, Readline will inhibit word completion. |
| Completion characters will be inserted into the line as if they had |
| been mapped to <CODE>self-insert</CODE>. The default is <SAMP>`off'</SAMP>. |
| <P> |
| |
| <DT><CODE>editing-mode</CODE> |
| <DD><A NAME="IDX11"></A> |
| The <CODE>editing-mode</CODE> variable controls which default set of |
| key bindings is used. By default, Readline starts up in Emacs editing |
| mode, where the keystrokes are most similar to Emacs. This variable can be |
| set to either <SAMP>`emacs'</SAMP> or <SAMP>`vi'</SAMP>. |
| <P> |
| |
| <DT><CODE>enable-keypad</CODE> |
| <DD><A NAME="IDX12"></A> |
| When set to <SAMP>`on'</SAMP>, Readline will try to enable the application |
| keypad when it is called. Some systems need this to enable the |
| arrow keys. The default is <SAMP>`off'</SAMP>. |
| <P> |
| |
| <DT><CODE>expand-tilde</CODE> |
| <DD><A NAME="IDX13"></A> |
| If set to <SAMP>`on'</SAMP>, tilde expansion is performed when Readline |
| attempts word completion. The default is <SAMP>`off'</SAMP>. |
| <P> |
| |
| <DT><CODE>history-preserve-point</CODE> |
| <DD><A NAME="IDX14"></A> |
| If set to <SAMP>`on'</SAMP>, the history code attempts to place point at the |
| same location on each history line retrieved with <CODE>previous-history</CODE> |
| or <CODE>next-history</CODE>. The default is <SAMP>`off'</SAMP>. |
| <P> |
| |
| <DT><CODE>horizontal-scroll-mode</CODE> |
| <DD><A NAME="IDX15"></A> |
| This variable can be set to either <SAMP>`on'</SAMP> or <SAMP>`off'</SAMP>. Setting it |
| to <SAMP>`on'</SAMP> means that the text of the lines being edited will scroll |
| horizontally on a single screen line when they are longer than the width |
| of the screen, instead of wrapping onto a new screen line. By default, |
| this variable is set to <SAMP>`off'</SAMP>. |
| <P> |
| |
| <DT><CODE>input-meta</CODE> |
| <DD><A NAME="IDX16"></A> |
| <A NAME="IDX17"></A> |
| If set to <SAMP>`on'</SAMP>, Readline will enable eight-bit input (it |
| will not clear the eighth bit in the characters it reads), |
| regardless of what the terminal claims it can support. The |
| default value is <SAMP>`off'</SAMP>. The name <CODE>meta-flag</CODE> is a |
| synonym for this variable. |
| <P> |
| |
| <DT><CODE>isearch-terminators</CODE> |
| <DD><A NAME="IDX18"></A> |
| The string of characters that should terminate an incremental search without |
| subsequently executing the character as a command (see section <A HREF="rluserman.html#SEC8">1.2.5 Searching for Commands in the History</A>). |
| If this variable has not been given a value, the characters <KBD>ESC</KBD> and |
| <KBD>C-J</KBD> will terminate an incremental search. |
| <P> |
| |
| <DT><CODE>keymap</CODE> |
| <DD><A NAME="IDX19"></A> |
| Sets Readline's idea of the current keymap for key binding commands. |
| Acceptable <CODE>keymap</CODE> names are |
| <CODE>emacs</CODE>, |
| <CODE>emacs-standard</CODE>, |
| <CODE>emacs-meta</CODE>, |
| <CODE>emacs-ctlx</CODE>, |
| <CODE>vi</CODE>, |
| <CODE>vi-move</CODE>, |
| <CODE>vi-command</CODE>, and |
| <CODE>vi-insert</CODE>. |
| <CODE>vi</CODE> is equivalent to <CODE>vi-command</CODE>; <CODE>emacs</CODE> is |
| equivalent to <CODE>emacs-standard</CODE>. The default value is <CODE>emacs</CODE>. |
| The value of the <CODE>editing-mode</CODE> variable also affects the |
| default keymap. |
| <P> |
| |
| <DT><CODE>mark-directories</CODE> |
| <DD>If set to <SAMP>`on'</SAMP>, completed directory names have a slash |
| appended. The default is <SAMP>`on'</SAMP>. |
| <P> |
| |
| <DT><CODE>mark-modified-lines</CODE> |
| <DD><A NAME="IDX20"></A> |
| This variable, when set to <SAMP>`on'</SAMP>, causes Readline to display an |
| asterisk (<SAMP>`*'</SAMP>) at the start of history lines which have been modified. |
| This variable is <SAMP>`off'</SAMP> by default. |
| <P> |
| |
| <DT><CODE>mark-symlinked-directories</CODE> |
| <DD><A NAME="IDX21"></A> |
| If set to <SAMP>`on'</SAMP>, completed names which are symbolic links |
| to directories have a slash appended (subject to the value of |
| <CODE>mark-directories</CODE>). |
| The default is <SAMP>`off'</SAMP>. |
| <P> |
| |
| <DT><CODE>match-hidden-files</CODE> |
| <DD><A NAME="IDX22"></A> |
| This variable, when set to <SAMP>`on'</SAMP>, causes Readline to match files whose |
| names begin with a <SAMP>`.'</SAMP> (hidden files) when performing filename |
| completion, unless the leading <SAMP>`.'</SAMP> is |
| supplied by the user in the filename to be completed. |
| This variable is <SAMP>`on'</SAMP> by default. |
| <P> |
| |
| <DT><CODE>output-meta</CODE> |
| <DD><A NAME="IDX23"></A> |
| If set to <SAMP>`on'</SAMP>, Readline will display characters with the |
| eighth bit set directly rather than as a meta-prefixed escape |
| sequence. The default is <SAMP>`off'</SAMP>. |
| <P> |
| |
| <DT><CODE>page-completions</CODE> |
| <DD><A NAME="IDX24"></A> |
| If set to <SAMP>`on'</SAMP>, Readline uses an internal <CODE>more</CODE>-like pager |
| to display a screenful of possible completions at a time. |
| This variable is <SAMP>`on'</SAMP> by default. |
| <P> |
| |
| <DT><CODE>print-completions-horizontally</CODE> |
| <DD>If set to <SAMP>`on'</SAMP>, Readline will display completions with matches |
| sorted horizontally in alphabetical order, rather than down the screen. |
| The default is <SAMP>`off'</SAMP>. |
| <P> |
| |
| <DT><CODE>show-all-if-ambiguous</CODE> |
| <DD><A NAME="IDX25"></A> |
| This alters the default behavior of the completion functions. If |
| set to <SAMP>`on'</SAMP>, |
| words which have more than one possible completion cause the |
| matches to be listed immediately instead of ringing the bell. |
| The default value is <SAMP>`off'</SAMP>. |
| <P> |
| |
| <DT><CODE>show-all-if-unmodified</CODE> |
| <DD><A NAME="IDX26"></A> |
| This alters the default behavior of the completion functions in |
| a fashion similar to <VAR>show-all-if-ambiguous</VAR>. |
| If set to <SAMP>`on'</SAMP>, |
| words which have more than one possible completion without any |
| possible partial completion (the possible completions don't share |
| a common prefix) cause the matches to be listed immediately instead |
| of ringing the bell. |
| The default value is <SAMP>`off'</SAMP>. |
| <P> |
| |
| <DT><CODE>visible-stats</CODE> |
| <DD><A NAME="IDX27"></A> |
| If set to <SAMP>`on'</SAMP>, a character denoting a file's type |
| is appended to the filename when listing possible |
| completions. The default is <SAMP>`off'</SAMP>. |
| <P> |
| |
| </DL> |
| <P> |
| |
| <DT>Key Bindings |
| <DD>The syntax for controlling key bindings in the init file is |
| simple. First you need to find the name of the command that you |
| want to change. The following sections contain tables of the command |
| name, the default keybinding, if any, and a short description of what |
| the command does. |
| <P> |
| |
| Once you know the name of the command, simply place on a line |
| in the init file the name of the key |
| you wish to bind the command to, a colon, and then the name of the |
| command. The name of the key |
| can be expressed in different ways, depending on what you find most |
| comfortable. |
| </P><P> |

| In addition to command names, readline allows keys to be bound |
| to a string that is inserted when the key is pressed (a <VAR>macro</VAR>). |

| <DL COMPACT> |
| <DT><VAR>keyname</VAR>: <VAR>function-name</VAR> or <VAR>macro</VAR> |

| <H3> 1.3.2 Conditional Init Constructs </H3> |
| <!--docid::SEC11::--> |
| <P> |
| |
| 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. |
| </P><P> |
| |
| <DL COMPACT> |
| <DT><CODE>$if</CODE> |
| <DD>The <CODE>$if</CODE> 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. |
| <P> |
| |
| <DL COMPACT> |
| <DT><CODE>mode</CODE> |
| <DD>The <CODE>mode=</CODE> form of the <CODE>$if</CODE> directive is used to test |
| whether Readline is in <CODE>emacs</CODE> or <CODE>vi</CODE> mode. |
| This may be used in conjunction |
| with the <SAMP>`set keymap'</SAMP> command, for instance, to set bindings in |
| the <CODE>emacs-standard</CODE> and <CODE>emacs-ctlx</CODE> keymaps only if |
| Readline is starting out in <CODE>emacs</CODE> mode. |
| <P> |
| |
| <DT><CODE>term</CODE> |
| <DD>The <CODE>term=</CODE> form may be used to include terminal-specific |
| key bindings, perhaps to bind the key sequences output by the |
| terminal's function keys. The word on the right side of the |
| <SAMP>`='</SAMP> is tested against both the full name of the terminal and |
| the portion of the terminal name before the first <SAMP>`-'</SAMP>. This |
| allows <CODE>sun</CODE> to match both <CODE>sun</CODE> and <CODE>sun-cmd</CODE>, |
| for instance. |
| <P> |
| |
| <DT><CODE>application</CODE> |
| <DD>The <VAR>application</VAR> construct is used to include |
| application-specific settings. Each program using the Readline |
| library sets the <VAR>application name</VAR>, and you can test for |
| a particular value. |
| This could be used to bind key sequences to functions useful for |
| a specific program. For instance, the following command adds a |
| key sequence that quotes the current or previous word in Bash: |
| <TABLE><tr><td> </td><td class=example><pre>$if Bash |
| # Quote the current or previous word |
| "\C-xq": "\eb\"\ef\"" |
| $endif |
| </pre></td></tr></table></DL> |
| <P> |
| |
| <DT><CODE>$endif</CODE> |
| <DD>This command, as seen in the previous example, terminates an |
| <CODE>$if</CODE> command. |
| <P> |
| |
| <DT><CODE>$else</CODE> |
| <DD>Commands in this branch of the <CODE>$if</CODE> directive are executed if |
| the test fails. |
| <P> |
| |
| <DT><CODE>$include</CODE> |
| <DD>This directive takes a single filename as an argument and reads commands |
| and bindings from that file. |
| For example, the following directive reads from <TT>`/etc/inputrc'</TT>: |
| <TABLE><tr><td> </td><td class=example><pre>$include /etc/inputrc |
| </pre></td></tr></table></DL> |

| <!--docid::SEC22::--> |
| <P> |
| |
| While the Readline library does not have a full set of <CODE>vi</CODE> |
| editing functions, it does contain enough to allow simple editing |
| of the line. The Readline <CODE>vi</CODE> mode behaves as specified in |
| the POSIX 1003.2 standard. |
| </P><P> |
| |
| In order to switch interactively between <CODE>emacs</CODE> and <CODE>vi</CODE> |
| editing modes, use the command <KBD>M-C-j</KBD> (bound to emacs-editing-mode |
| when in <CODE>vi</CODE> mode and to vi-editing-mode in <CODE>emacs</CODE> mode). |
| The Readline default is <CODE>emacs</CODE> mode. |
| </P><P> |
| |
| When you enter a line in <CODE>vi</CODE> mode, you are already placed in |
| `insertion' mode, as if you had typed an <SAMP>`i'</SAMP>. Pressing <KBD>ESC</KBD> |
| switches you into `command' mode, where you can edit the text of the |
| line with the standard <CODE>vi</CODE> movement keys, move to previous |
| history lines with <SAMP>`k'</SAMP> and subsequent lines with <SAMP>`j'</SAMP>, and |
| so forth. |

| PREAMBLE |
| <P> |
| |
| The purpose of this License is to make a manual, textbook, or other |
| functional and useful document <EM>free</EM> in the sense of freedom: to |
| assure everyone the effective freedom to copy and redistribute it, |
| with or without modifying it, either commercially or noncommercially. |
| Secondarily, this License preserves for the author and publisher a way |
| to get credit for their work, while not being considered responsible |
| for modifications made by others. |
| </P><P> |
| |
| This License is a kind of "copyleft", which means that derivative |
| works of the document must themselves be free in the same sense. It |
| complements the GNU General Public License, which is a copyleft |
| license designed for free software. |
| </P><P> |
| |
| We have designed this License in order to use it for manuals for free |
| software, because free software needs free documentation: a free |
| program should come with manuals providing the same freedoms that the |
| software does. But this License is not limited to software manuals; |
| it can be used for any textual work, regardless of subject matter or |
| whether it is published as a printed book. We recommend this License |
| principally for works whose purpose is instruction or reference. |
| </P><P> |
| |
| <LI> |
| APPLICABILITY AND DEFINITIONS |
| <P> |
| |
| This License applies to any manual or other work, in any medium, that |
| contains a notice placed by the copyright holder saying it can be |
| distributed under the terms of this License. Such a notice grants a |
| world-wide, royalty-free license, unlimited in duration, to use that |
| work under the conditions stated herein. The "Document", below, |
| refers to any such manual or work. Any member of the public is a |
| licensee, and is addressed as "you". You accept the license if you |
| copy, modify or distribute the work in a way requiring permission |
| under copyright law. |
| </P><P> |
| |
| A "Modified Version" of the Document means any work containing the |
| Document or a portion of it, either copied verbatim, or with |
| modifications and/or translated into another language. |
| </P><P> |
| |
| A "Secondary Section" is a named appendix or a front-matter section |
| of the Document that deals exclusively with the relationship of the |
| publishers or authors of the Document to the Document's overall |
| subject (or to related matters) and contains nothing that could fall |
| directly within that overall subject. (Thus, if the Document is in |
| part a textbook of mathematics, a Secondary Section may not explain |
| any mathematics.) The relationship could be a matter of historical |
| connection with the subject or with related matters, or of legal, |
| commercial, philosophical, ethical or political position regarding |
| them. |
| </P><P> |
| |
| The "Invariant Sections" are certain Secondary Sections whose titles |
| are designated, as being those of Invariant Sections, in the notice |
| that says that the Document is released under this License. If a |
| section does not fit the above definition of Secondary then it is not |
| allowed to be designated as Invariant. The Document may contain zero |
| Invariant Sections. If the Document does not identify any Invariant |
| Sections then there are none. |
| </P><P> |
| |
| The "Cover Texts" are certain short passages of text that are listed, |
| as Front-Cover Texts or Back-Cover Texts, in the notice that says that |
| the Document is released under this License. A Front-Cover Text may |
| be at most 5 words, and a Back-Cover Text may be at most 25 words. |
| </P><P> |
| |
| A "Transparent" copy of the Document means a machine-readable copy, |
| represented in a format whose specification is available to the |
| general public, that is suitable for revising the document |
| straightforwardly with generic text editors or (for images composed of |
| pixels) generic paint programs or (for drawings) some widely available |
| drawing editor, and that is suitable for input to text formatters or |
| for automatic translation to a variety of formats suitable for input |
| to text formatters. A copy made in an otherwise Transparent file |
| format whose markup, or absence of markup, has been arranged to thwart |
| or discourage subsequent modification by readers is not Transparent. |
| An image format is not Transparent if used for any substantial amount |
| of text. A copy that is not "Transparent" is called "Opaque". |
| </P><P> |
| |
| Examples of suitable formats for Transparent copies include plain |
| ASCII without markup, Texinfo input format, LaTeX input |
| format, <FONT SIZE="-1">SGML</FONT> or <FONT SIZE="-1">XML</FONT> using a publicly available |
| <FONT SIZE="-1">DTD</FONT>, and standard-conforming simple <FONT SIZE="-1">HTML</FONT>, |
| PostScript or <FONT SIZE="-1">PDF</FONT> designed for human modification. Examples |
| of transparent image formats include <FONT SIZE="-1">PNG</FONT>, <FONT SIZE="-1">XCF</FONT> and |
| <FONT SIZE="-1">JPG</FONT>. Opaque formats include proprietary formats that can be |
| read and edited only by proprietary word processors, <FONT SIZE="-1">SGML</FONT> or |
| <FONT SIZE="-1">XML</FONT> for which the <FONT SIZE="-1">DTD</FONT> and/or processing tools are |
| not generally available, and the machine-generated <FONT SIZE="-1">HTML</FONT>, |
| PostScript or <FONT SIZE="-1">PDF</FONT> produced by some word processors for |
| output purposes only. |
| </P><P> |
| |
| The "Title Page" means, for a printed book, the title page itself, |
| plus such following pages as are needed to hold, legibly, the material |
| this License requires to appear in the title page. For works in |
| formats which do not have any title page as such, "Title Page" means |
| the text near the most prominent appearance of the work's title, |
| preceding the beginning of the body of the text. |
| </P><P> |
| |
| A section "Entitled XYZ" means a named subunit of the Document whose |
| title either is precisely XYZ or contains XYZ in parentheses following |
| text that translates XYZ in another language. (Here XYZ stands for a |
| specific section name mentioned below, such as "Acknowledgements", |
| "Dedications", "Endorsements", or "History".) To "Preserve the Title" |
| of such a section when you modify the Document means that it remains a |
| section "Entitled XYZ" according to this definition. |
| </P><P> |
| |
| The Document may include Warranty Disclaimers next to the notice which |
| states that this License applies to the Document. These Warranty |
| Disclaimers are considered to be included by reference in this |
| License, but only as regards disclaiming warranties: any other |
| implication that these Warranty Disclaimers may have is void and has |
| no effect on the meaning of this License. |
| </P><P> |
| |
| <LI> |
| VERBATIM COPYING |
| <P> |
| |
| You may copy and distribute the Document in any medium, either |
| commercially or noncommercially, provided that this License, the |
| copyright notices, and the license notice saying this License applies |
| to the Document are reproduced in all copies, and that you add no other |
| conditions whatsoever to those of this License. You may not use |
| technical measures to obstruct or control the reading or further |
| copying of the copies you make or distribute. However, you may accept |
| compensation in exchange for copies. If you distribute a large enough |
| number of copies you must also follow the conditions in section 3. |
| </P><P> |
| |
| You may also lend copies, under the same conditions stated above, and |
| you may publicly display copies. |
| </P><P> |
| |
| <LI> |
| COPYING IN QUANTITY |
| <P> |
| |
| If you publish printed copies (or copies in media that commonly have |
| printed covers) of the Document, numbering more than 100, and the |
| Document's license notice requires Cover Texts, you must enclose the |
| copies in covers that carry, clearly and legibly, all these Cover |
| Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on |
| the back cover. Both covers must also clearly and legibly identify |
| you as the publisher of these copies. The front cover must present |
| the full title with all words of the title equally prominent and |
| visible. You may add other material on the covers in addition. |
| Copying with changes limited to the covers, as long as they preserve |
| the title of the Document and satisfy these conditions, can be treated |
| as verbatim copying in other respects. |
| </P><P> |
| |
| If the required texts for either cover are too voluminous to fit |
| legibly, you should put the first ones listed (as many as fit |
| reasonably) on the actual cover, and continue the rest onto adjacent |
| pages. |
| </P><P> |
| |
| If you publish or distribute Opaque copies of the Document numbering |
| more than 100, you must either include a machine-readable Transparent |
| copy along with each Opaque copy, or state in or with each Opaque copy |
| a computer-network location from which the general network-using |
| public has access to download using public-standard network protocols |
| a complete Transparent copy of the Document, free of added material. |
| If you use the latter option, you must take reasonably prudent steps, |
| when you begin distribution of Opaque copies in quantity, to ensure |
| that this Transparent copy will remain thus accessible at the stated |
| location until at least one year after the last time you distribute an |
| Opaque copy (directly or through your agents or retailers) of that |
| edition to the public. |
| </P><P> |
| |
| It is requested, but not required, that you contact the authors of the |
| Document well before redistributing any large number of copies, to give |
| them a chance to provide you with an updated version of the Document. |
| </P><P> |
| |
| <LI> |
| MODIFICATIONS |
| <P> |
| |
| You may copy and distribute a Modified Version of the Document under |
| the conditions of sections 2 and 3 above, provided that you release |
| the Modified Version under precisely this License, with the Modified |
| Version filling the role of the Document, thus licensing distribution |
| and modification of the Modified Version to whoever possesses a copy |
| of it. In addition, you must do these things in the Modified Version: |
| </P><P> |
| |
| <OL> |
| <LI> |
| Use in the Title Page (and on the covers, if any) a title distinct |
| from that of the Document, and from those of previous versions |
| (which should, if there were any, be listed in the History section |
| of the Document). You may use the same title as a previous version |
| if the original publisher of that version gives permission. |
| <P> |
| |
| <LI> |
| List on the Title Page, as authors, one or more persons or entities |
| responsible for authorship of the modifications in the Modified |
| Version, together with at least five of the principal authors of the |
| Document (all of its principal authors, if it has fewer than five), |
| unless they release you from this requirement. |
| <P> |
| |
| <LI> |
| State on the Title page the name of the publisher of the |
| Modified Version, as the publisher. |
| <P> |
| |
| <LI> |
| Preserve all the copyright notices of the Document. |
| <P> |
| |
| <LI> |
| Add an appropriate copyright notice for your modifications |
| adjacent to the other copyright notices. |
| <P> |
| |
| <LI> |
| Include, immediately after the copyright notices, a license notice |
| giving the public permission to use the Modified Version under the |
| terms of this License, in the form shown in the Addendum below. |
| <P> |
| |
| <LI> |
| Preserve in that license notice the full lists of Invariant Sections |
| and required Cover Texts given in the Document's license notice. |
| <P> |
| |
| <LI> |
| Include an unaltered copy of this License. |
| <P> |
| |
| <LI> |
| Preserve the section Entitled "History", Preserve its Title, and add |
| to it an item stating at least the title, year, new authors, and |
| publisher of the Modified Version as given on the Title Page. If |
| there is no section Entitled "History" in the Document, create one |
| stating the title, year, authors, and publisher of the Document as |
| given on its Title Page, then add an item describing the Modified |
| Version as stated in the previous sentence. |
| <P> |
| |
| <LI> |
| Preserve the network location, if any, given in the Document for |
| public access to a Transparent copy of the Document, and likewise |
| the network locations given in the Document for previous versions |
| it was based on. These may be placed in the "History" section. |
| You may omit a network location for a work that was published at |
| least four years before the Document itself, or if the original |
| publisher of the version it refers to gives permission. |
| <P> |
| |
| <LI> |
| For any section Entitled "Acknowledgements" or "Dedications", Preserve |
| the Title of the section, and preserve in the section all the |
| substance and tone of each of the contributor acknowledgements and/or |
| dedications given therein. |
| <P> |
| |
| <LI> |
| Preserve all the Invariant Sections of the Document, |
| unaltered in their text and in their titles. Section numbers |
| or the equivalent are not considered part of the section titles. |
| <P> |
| |
| <LI> |
| Delete any section Entitled "Endorsements". Such a section |
| may not be included in the Modified Version. |
| <P> |
| |
| <LI> |
| Do not retitle any existing section to be Entitled "Endorsements" or |
| to conflict in title with any Invariant Section. |
| <P> |
| |
| <LI> |
| Preserve any Warranty Disclaimers. |
| </OL> |
| <P> |
| |
| If the Modified Version includes new front-matter sections or |
| appendices that qualify as Secondary Sections and contain no material |
| copied from the Document, you may at your option designate some or all |
| of these sections as invariant. To do this, add their titles to the |
| list of Invariant Sections in the Modified Version's license notice. |
| These titles must be distinct from any other section titles. |
| </P><P> |
| |
| You may add a section Entitled "Endorsements", provided it contains |
| nothing but endorsements of your Modified Version by various |
| parties--for example, statements of peer review or that the text has |
| been approved by an organization as the authoritative definition of a |
| standard. |
| </P><P> |
| |
| You may add a passage of up to five words as a Front-Cover Text, and a |
| passage of up to 25 words as a Back-Cover Text, to the end of the list |
| of Cover Texts in the Modified Version. Only one passage of |
| Front-Cover Text and one of Back-Cover Text may be added by (or |
| through arrangements made by) any one entity. If the Document already |
| includes a cover text for the same cover, previously added by you or |
| by arrangement made by the same entity you are acting on behalf of, |
| you may not add another; but you may replace the old one, on explicit |
| permission from the previous publisher that added the old one. |
| </P><P> |
| |
| The author(s) and publisher(s) of the Document do not by this License |
| give permission to use their names for publicity for or to assert or |
| imply endorsement of any Modified Version. |
| </P><P> |
| |
| <LI> |
| COMBINING DOCUMENTS |
| <P> |
| |
| You may combine the Document with other documents released under this |
| License, under the terms defined in section 4 above for modified |
| versions, provided that you include in the combination all of the |
| Invariant Sections of all of the original documents, unmodified, and |
| list them all as Invariant Sections of your combined work in its |
| license notice, and that you preserve all their Warranty Disclaimers. |
| </P><P> |
| |
| The combined work need only contain one copy of this License, and |
| multiple identical Invariant Sections may be replaced with a single |
| copy. If there are multiple Invariant Sections with the same name but |
| different contents, make the title of each such section unique by |
| adding at the end of it, in parentheses, the name of the original |
| author or publisher of that section if known, or else a unique number. |
| Make the same adjustment to the section titles in the list of |
| Invariant Sections in the license notice of the combined work. |
| </P><P> |
| |
| In the combination, you must combine any sections Entitled "History" |
| in the various original documents, forming one section Entitled |
| "History"; likewise combine any sections Entitled "Acknowledgements", |
| and any sections Entitled "Dedications". You must delete all |
| sections Entitled "Endorsements." |
| </P><P> |
| |
| <LI> |
| COLLECTIONS OF DOCUMENTS |
| <P> |
| |
| You may make a collection consisting of the Document and other documents |
| released under this License, and replace the individual copies of this |
| License in the various documents with a single copy that is included in |
| the collection, provided that you follow the rules of this License for |
| verbatim copying of each of the documents in all other respects. |
| </P><P> |
| |
| You may extract a single document from such a collection, and distribute |
| it individually under this License, provided you insert a copy of this |
| License into the extracted document, and follow this License in all |
| other respects regarding verbatim copying of that document. |
| </P><P> |
| |
| <LI> |
| AGGREGATION WITH INDEPENDENT WORKS |
| <P> |
| |
| A compilation of the Document or its derivatives with other separate |
| and independent documents or works, in or on a volume of a storage or |
| distribution medium, is called an "aggregate" if the copyright |
| resulting from the compilation is not used to limit the legal rights |
| of the compilation's users beyond what the individual works permit. |
| When the Document is included an aggregate, this License does not |
| apply to the other works in the aggregate which are not themselves |
| derivative works of the Document. |
| </P><P> |
| |
| If the Cover Text requirement of section 3 is applicable to these |
| copies of the Document, then if the Document is less than one half of |
| the entire aggregate, the Document's Cover Texts may be placed on |
| covers that bracket the Document within the aggregate, or the |
| electronic equivalent of covers if the Document is in electronic form. |
| Otherwise they must appear on printed covers that bracket the whole |
| aggregate. |
| </P><P> |
| |
| <LI> |
| TRANSLATION |
| <P> |
| |
| Translation is considered a kind of modification, so you may |
| distribute translations of the Document under the terms of section 4. |
| Replacing Invariant Sections with translations requires special |
| permission from their copyright holders, but you may include |
| translations of some or all Invariant Sections in addition to the |
| original versions of these Invariant Sections. You may include a |
| translation of this License, and all the license notices in the |
| Document, and any Warranty Disclaimers, provided that you also include |
| the original English version of this License and the original versions |
| of those notices and disclaimers. In case of a disagreement between |
| the translation and the original version of this License or a notice |
| or disclaimer, the original version will prevail. |
| </P><P> |
| |
| If a section in the Document is Entitled "Acknowledgements", |
| "Dedications", or "History", the requirement (section 4) to Preserve |
| its Title (section 1) will typically require changing the actual |
| title. |
| </P><P> |
| |
| <LI> |
| TERMINATION |
| <P> |
| |
| You may not copy, modify, sublicense, or distribute the Document except |
| as expressly provided for under this License. Any other attempt to |
| copy, modify, sublicense or distribute the Document is void, and will |
| automatically terminate your rights under this License. However, |
| parties who have received copies, or rights, from you under this |
| License will not have their licenses terminated so long as such |
| parties remain in full compliance. |
| </P><P> |
| |
| <LI> |
| FUTURE REVISIONS OF THIS LICENSE |
| <P> |
| |
| The Free Software Foundation may publish new, revised versions |
| of the GNU Free Documentation License from time to time. Such new |
| versions will be similar in spirit to the present version, but may |
| differ in detail to address new problems or concerns. See |
| <A HREF="http://www.gnu.org/copyleft/">http://www.gnu.org/copyleft/</A>. |
| </P><P> |
| |
| Each version of the License is given a distinguishing version number. |
