Otherwise, nothing is changed, and a -1 is -returned. - -.Fn2 int history_search_prefix "const char *string" "int direction" -Search the history for \fIstring\fP, starting at the current history -offset. The search is anchored: matching lines must begin with -\fIstring\fP. If \fIdirection\fP is less than 0, then the search is -through previous entries, otherwise through subsequent entries. -If \fIstring\fP is found, then the -current history index is set to that entry, and the return value is 0. -Otherwise, nothing is changed, and a -1 is returned. - -.Fn3 int history_search_pos "const char *string" "int direction" "int pos" -Search for \fIstring\fP in the history list, starting at \fIpos\fP, an -absolute index into the list. If \fIdirection\fP is negative, the search -proceeds backward from \fIpos\fP, otherwise forward. Returns the absolute -index of the history element where \fIstring\fP was found, or -1 otherwise. - -.SS Managing the History File -The History library can read the history from and write it to a file. -This section documents the functions for managing a history file. - -.Fn1 int read_history "const char *filename" -Add the contents of \fIfilename\fP to the history list, a line at a time. -If \fIfilename\fP is \fBNULL\fP, then read from \fI~/.history\fP. -Returns 0 if successful, or \fBerrno\fP if not. - -.Fn3 int read_history_range "const char *filename" "int from" "int to" -Read a range of lines from \fIfilename\fP, adding them to the history list. -Start reading at line \fIfrom\fP and end at \fIto\fP. -If \fIfrom\fP is zero, start at the beginning. If \fIto\fP is less than -\fIfrom\fP, then read until the end of the file. If \fIfilename\fP is -\fBNULL\fP, then read from \fI~/.history\fP. Returns 0 if successful, -or \fBerrno\fP if not. - -.Fn1 int write_history "const char *filename" -Write the current history to \fIfilename\fP, overwriting \fIfilename\fP -if necessary. -If \fIfilename\fP is \fBNULL\fP, then write the history list to \fI~/.history\fP. -Returns 0 on success, or \fBerrno\fP on a read or write error. - - -.Fn2 int append_history "int nelements" "const char *filename" -Append the last \fInelements\fP of the history list to \fIfilename\fP. -If \fIfilename\fP is \fBNULL\fP, then append to \fI~/.history\fP. -Returns 0 on success, or \fBerrno\fP on a read or write error. - -.Fn2 int history_truncate_file "const char *filename" "int nlines" -Truncate the history file \fIfilename\fP, leaving only the last -\fInlines\fP lines. -If \fIfilename\fP is \fBNULL\fP, then \fI~/.history\fP is truncated. -Returns 0 on success, or \fBerrno\fP on failure. - -.SS History Expansion - -These functions implement history expansion. - -.Fn2 int history_expand "char *string" "char **output" -Expand \fIstring\fP, placing the result into \fIoutput\fP, a pointer -to a string. Returns: -.RS -.PD 0 -.TP -0 -If no expansions took place (or, if the only change in -the text was the removal of escape characters preceding the history expansion -character); -.TP -1 -if expansions did take place; -.TP --1 -if there was an error in expansion; -.TP -2 -if the returned line should be displayed, but not executed, -as with the \fB:p\fP modifier. -.PD -.RE -If an error ocurred in expansion, then \fIoutput\fP contains a descriptive -error message. - -.Fn3 "char *" get_history_event "const char *string" "int *cindex" "int qchar" -Returns the text of the history event beginning at \fIstring\fP + -\fI*cindex\fP. \fI*cindex\fP is modified to point to after the event -specifier. At function entry, \fIcindex\fP points to the index into -\fIstring\fP where the history event specification begins. \fIqchar\fP -is a character that is allowed to end the event specification in addition -to the ``normal'' terminating characters. - -.Fn1 "char **" history_tokenize "const char *string" -Return an array of tokens parsed out of \fIstring\fP, much as the -shell might. -The tokens are split on the characters in the -\fBhistory_word_delimiters\fP variable, -and shell quoting conventions are obeyed. - -.Fn3 "char *" history_arg_extract "int first" "int last" "const char *string" -Extract a string segment consisting of the \fIfirst\fP through \fIlast\fP -arguments present in \fIstring\fP.

If -.B prompt -is \fBNULL\fP or the empty string, no prompt is issued. -The line returned is allocated with -.IR malloc (3); -the caller must free it when finished. The line returned -has the final newline removed, so only the text of the line -remains. -.LP -.B 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. -.LP -This manual page describes only the most basic use of \fBreadline\fP. -Much more functionality is available; see -\fIThe GNU Readline Library\fP and \fIThe GNU History Library\fP -for additional information. -.SH RETURN VALUE -.LP -.B readline -returns the text of the line read. A blank line -returns the empty string. If -.B EOF -is encountered while reading a line, and the line is empty, -.B NULL -is returned. If an -.B EOF -is read with a non\-empty line, it is -treated as a newline. -.SH NOTATION -.LP -An emacs-style notation is used to denote -keystrokes. Control keys are denoted by C\-\fIkey\fR, e.g., C\-n -means Control\-N. Similarly, -.I meta -keys are denoted by M\-\fIkey\fR, so M\-x means Meta\-X. (On keyboards -without a -.I meta -key, M\-\fIx\fP means ESC \fIx\fP, i.e., press the Escape key -then the -.I x -key. This makes ESC the \fImeta prefix\fP. -The combination M\-C\-\fIx\fP means ESC\-Control\-\fIx\fP, -or press the Escape key -then hold the Control key while pressing the -.I x -key.) -.PP -Readline commands may be given numeric -.IR arguments , -which normally act as a repeat count. Sometimes, however, it is the -sign of the argument that is significant. Passing a negative argument -to a command that acts in the forward direction (e.g., \fBkill\-line\fP) -causes that command to act in a backward direction. Commands whose -behavior with arguments deviates from this are noted. -.PP -When a command is described as \fIkilling\fP text, the text -deleted is saved for possible future retrieval -(\fIyanking\fP). The killed text is saved in a -\fIkill ring\fP. 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. -.SH INITIALIZATION FILE -.LP -Readline is customized by putting commands in an initialization -file (the \fIinputrc\fP file). -The name of this file is taken from the value of the -.B INPUTRC -environment variable. If that variable is unset, the default is -.IR ~/.inputrc . -When a program which uses the readline library starts up, the -init file is read, and the key bindings and variables are set. -There are only a few basic constructs allowed in the -readline init file. Blank lines are ignored. -Lines beginning with a \fB#\fP are comments. -Lines beginning with a \fB$\fP indicate conditional constructs. -Other lines denote key bindings and variable settings. -Each program using this library may add its own commands -and bindings. -.PP -For example, placing -.RS -.PP -M\-Control\-u: universal\-argument -.RE -or -.RS -C\-Meta\-u: universal\-argument -.RE -.sp -into the -.I inputrc -would make M\-C\-u execute the readline command -.IR universal\-argument . -.PP -The following symbolic character names are recognized while -processing key bindings: -.IR DEL , -.IR ESC , -.IR ESCAPE , -.IR LFD , -.IR NEWLINE , -.IR RET , -.IR RETURN , -.IR RUBOUT , -.IR SPACE , -.IR SPC , -and -.IR TAB . -.PP -In addition to command names, readline allows keys to be bound -to a string that is inserted when the key is pressed (a \fImacro\fP). -.PP -.SS Key Bindings -.PP -The syntax for controlling key bindings in the -.I 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 \fIMeta\-\fP or \fIControl\-\fP -prefixes, or as a key sequence. -.PP -When using the form \fBkeyname\fP:\^\fIfunction-name\fP or \fImacro\fP, -.I keyname -is the name of a key spelled out in English. For example: -.sp -.RS -Control\-u: universal\-argument -.br -Meta\-Rubout: backward\-kill\-word -.br -Control\-o: "> output" -.RE -.LP -In the above example, -.I C\-u -is bound to the function -.BR universal\-argument , -.I M-DEL -is bound to the function -.BR backward\-kill\-word , -and -.I C\-o -is bound to run the macro -expressed on the right hand side (that is, to insert the text -.if t \f(CW> output\fP -.if n ``> output'' -into the line). -.PP -In the second form, \fB"keyseq"\fP:\^\fIfunction\-name\fP or \fImacro\fP, -.B keyseq -differs from -.B 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, but the symbolic character names -are not recognized. -.sp -.RS -"\eC\-u": universal\-argument -.br -"\eC\-x\eC\-r": re\-read\-init\-file -.br -"\ee[11~": "Function Key 1" -.RE -.PP -In this example, -.I C-u -is again bound to the function -.BR universal\-argument . -.I "C-x C-r" -is bound to the function -.BR re\-read\-init\-file , -and -.I "ESC [ 1 1 ~" -is bound to insert the text -.if t \f(CWFunction Key 1\fP. -.if n ``Function Key 1''. -.PP -The full set of GNU Emacs style escape sequences available when specifying -key sequences is -.RS -.PD 0 -.TP -.B \eC\- -control prefix -.TP -.B \eM\- -meta prefix -.TP -.B \ee -an escape character -.TP -.B \e\e -backslash -.TP -.B \e" -literal ", a double quote -.TP -.B \e' -literal ', a single quote -.RE -.PD -.PP -In addition to the GNU Emacs style escape sequences, a second -set of backslash escapes is available: -.RS -.PD 0 -.TP -.B \ea -alert (bell) -.TP -.B \eb -backspace -.TP -.B \ed -delete -.TP -.B \ef -form feed -.TP -.B \en -newline -.TP -.B \er -carriage return -.TP -.B \et -horizontal tab -.TP -.B \ev -vertical tab -.TP -.B \e\fInnn\fP -the character whose ASCII code is the octal value \fInnn\fP -(one to three digits) -.TP -.B \ex\fInnn\fP -the character whose ASCII code is the hexadecimal value \fInnn\fP -(one to three digits) -.RE -.PD -.PP -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 '. -.PP -.B Bash -allows the current readline key bindings to be displayed or modified -with the -.B bind -builtin command. The editing mode may be switched during interactive -use by using the -.B \-o -option to the -.B set -builtin command. Other programs using this library provide -similar mechanisms. The -.I inputrc -file may be edited and re-read if a program does not provide -any other means to incorporate new bindings. -.SS Variables -.PP -Readline has variables that can be used to further customize its -behavior. A variable may be set in the -.I inputrc -file with a statement of the form -.RS -.PP -\fBset\fP \fIvariable\-name\fP \fIvalue\fP -.RE -.PP -Except where noted, readline variables can take the values -.B On -or -.B Off -(without regard to case). -The variables and their default values are: -.PP -.PD 0 -.TP -.B bell\-style (audible) -Controls what happens when readline wants to ring the terminal bell. -If set to \fBnone\fP, readline never rings the bell. If set to -\fBvisible\fP, readline uses a visible bell if one is available. -If set to \fBaudible\fP, readline attempts to ring the terminal's bell. -.TP -.B comment\-begin (``#'') -The string that is inserted in \fBvi\fP mode when the -.B insert\-comment -command is executed. -This command is bound to -.B M\-# -in emacs mode and to -.B # -in vi command mode. -.TP -.B completion\-ignore\-case (Off) -If set to \fBOn\fP, readline performs filename matching and completion -in a case\-insensitive fashion. -.TP -.B completion\-query\-items (100) -This determines when the user is queried about viewing -the number of possible completions -generated by the \fBpossible\-completions\fP 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. -.TP -.B convert\-meta (On) -If set to \fBOn\fP, readline will convert characters with the -eighth bit set to an ASCII key sequence -by stripping the eighth bit and prefixing it with an -escape character (in effect, using escape as the \fImeta prefix\fP). -.TP -.B disable\-completion (Off) -If set to \fBOn\fP, readline will inhibit word completion. Completion -characters will be inserted into the line as if they had been -mapped to \fBself-insert\fP. -.TP -.B editing\-mode (emacs) -Controls whether readline begins with a set of key bindings similar -to emacs or vi. -.B editing\-mode -can be set to either -.B emacs -or -.BR vi . -.TP -.B enable\-keypad (Off) -When set to \fBOn\fP, readline will try to enable the application -keypad when it is called. Some systems need this to enable the -arrow keys. -.TP -.B expand\-tilde (Off) -If set to \fBon\fP, tilde expansion is performed when readline -attempts word completion. -.TP -.B horizontal\-scroll\-mode (Off) -When set to \fBOn\fP, 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. -.TP -.B input\-meta (Off) -If set to \fBOn\fP, 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 name -.B meta\-flag -is a synonym for this variable. -.TP -.B 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 -\fIESC\fP and \fIC\-J\fP will terminate an incremental search. -.TP -.B keymap (emacs) -Set the current readline keymap. The set of legal keymap names is -\fIemacs, emacs-standard, emacs-meta, emacs-ctlx, vi, vi-move, -vi-command\fP, and -.IR vi-insert . -\fIvi\fP is equivalent to \fIvi-command\fP; \fIemacs\fP is -equivalent to \fIemacs-standard\fP. The default value is -.IR emacs . -The value of -.B editing\-mode -also affects the default keymap. -.TP -.B mark\-directories (On) -If set to \fBOn\fP, completed directory names have a slash -appended. -.TP -.B mark\-modified\-lines (Off) -If set to \fBOn\fP, history lines that have been modified are displayed -with a preceding asterisk (\fB*\fP). -.TP -.B output\-meta (Off) -If set to \fBOn\fP, readline will display characters with the -eighth bit set directly rather than as a meta-prefixed escape -sequence. -.TP -.B print\-completions\-horizontally (Off) -If set to \fBOn\fP, readline will display completions with matches -sorted horizontally in alphabetical order, rather than down the screen. -.TP -.B show\-all\-if\-ambiguous (Off) -This alters the default behavior of the completion functions. If -set to -.BR on , -words which have more than one possible completion cause the -matches to be listed immediately instead of ringing the bell. -.TP -.B visible\-stats (Off) -If set to \fBOn\fP, a character denoting a file's type as reported -by \fIstat\fP(2) is appended to the filename when listing possible -completions. -.PD -.SS Conditional Constructs -.PP -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. -.IP \fB$if\fP -The -.B $if -construct allows bindings to be made based on the -editing mode, the terminal being used, or the application using -readline. The text of the test extends to the end of the line; -no characters are required to isolate it. -.RS -.IP \fBmode\fP -The \fBmode=\fP form of the \fB$if\fP directive is used to test -whether readline is in emacs or vi mode. -This may be used in conjunction -with the \fBset keymap\fP command, for instance, to set bindings in -the \fIemacs-standard\fP and \fIemacs-ctlx\fP keymaps only if -readline is starting out in emacs mode. -.IP \fBterm\fP -The \fBterm=\fP 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 -.B = -is tested against the full name of the terminal and the portion -of the terminal name before the first \fB\-\fP. This allows -.I sun -to match both -.I sun -and -.IR sun\-cmd , -for instance. -.IP \fBapplication\fP -The \fBapplication\fP construct is used to include -application-specific settings. Each program using the readline -library sets the \fIapplication name\fP, and an initialization -file can test for a particular value. -This could be used to bind key sequences to functions useful for -a specific program. For instance, the following command adds a -key sequence that quotes the current or previous word in Bash: -.sp 1 -.RS -.nf -\fB$if\fP Bash -# Quote the current or previous word -"\eC-xq": "\eeb\e"\eef\e"" -\fB$endif\fP -.fi -.RE -.RE -.IP \fB$endif\fP -This command, as seen in the previous example, terminates an -\fB$if\fP command. -.IP \fB$else\fP -Commands in this branch of the \fB$if\fP directive are executed if -the test fails. -.IP \fB$include\fP -This directive takes a single filename as an argument and reads commands -and bindings from that file. For example, the following directive -would read \fI/etc/inputrc\fP: -.sp 1 -.RS -.nf -\fB$include\fP \^ \fI/etc/inputrc\fP -.fi -.RE -.SH SEARCHING -.PP -Readline provides commands for searching through the command history -for lines containing a specified string. -There are two search modes: -.I incremental -and -.IR non-incremental . -.PP -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 -\fBC\-r\fP. Typing \fBC\-s\fP searches forward through the history. -The characters present in the value of the \fBisearch-terminators\fP -variable are used to terminate an incremental search. -If that variable has not been assigned a value the \fIEscape\fP and -\fBC\-J\fP characters will terminate an incremental search. -\fBC\-G\fP 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. -.PP -To find other matching entries in the history list, type \fBC\-s\fP or -\fBC\-r\fP as appropriate. -This will search backward or forward 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. -A movement command will terminate the search, make the last line found -the current line, and begin editing. -.PP -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. -.SH EDITING COMMANDS -.PP -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. -.PP -In the following descriptions, \fIpoint\fP refers to the current cursor -position, and \fImark\fP refers to a cursor position saved by the -\fBset\-mark\fP command. -The text between the point and mark is referred to as the \fIregion\fP. -.SS Commands for Moving -.PP -.PD 0 -.TP -.B beginning\-of\-line (C\-a) -Move to the start of the current line. -.TP -.B end\-of\-line (C\-e) -Move to the end of the line. -.TP -.B forward\-char (C\-f) -Move forward a character. -.TP -.B backward\-char (C\-b) -Move back a character. -.TP -.B forward\-word (M\-f) -Move forward to the end of the next word.

This is an incremental search. -.TP -.B 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. -.TP -.B 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. -.TP -.B non\-incremental\-forward\-search\-history (M\-n) -Search forward through the history using a non-incremental search -for a string supplied by the user. -.TP -.B 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 \fIpoint\fP). -This is a non-incremental search. -.TP -.B 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. -.TP -.B yank\-nth\-arg (M\-C\-y) -Insert the first argument to the previous command (usually -the second word on the previous line) at point. -With an argument -.IR n , -insert the \fIn\fPth word from the previous command (the words -in the previous command begin with word 0). A negative argument -inserts the \fIn\fPth word from the end of the previous command. -.TP -.B -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 \fByank\-nth\-arg\fP. -Successive calls to \fByank\-last\-arg\fP move back through the history -list, inserting the last argument of each line in turn. -.PD -.SS Commands for Changing Text -.PP -.PD 0 -.TP -.B delete\-char (C\-d) -Delete the character at point.
