39 | .SH DESCRIPTION |
40 | .LP | |
41 | .B readline | |
42 | will read a line from the terminal | |
43 | and return it, using | |
44 | .B prompt | |
45 | as a prompt. If | |
46 | .B prompt | |
9255ee31 EZ |
47 | is \fBNULL\fP or the empty string, no prompt is issued. |
48 | The line returned is allocated with | |
49 | .IR malloc (3); | |
50 | the caller must free it when finished. The line returned | |
d60d9f65 SS |
51 | has the final newline removed, so only the text of the line |
52 | remains. | |
53 | .LP | |
54 | .B readline | |
55 | offers editing capabilities while the user is entering the | |
56 | line. | |
57 | By default, the line editing commands | |
58 | are similar to those of emacs. | |
59 | A vi\-style line editing interface is also available. | |
9255ee31 EZ |
60 | .LP |
61 | This manual page describes only the most basic use of \fBreadline\fP. | |
62 | Much more functionality is available; see | |
63 | \fIThe GNU Readline Library\fP and \fIThe GNU History Library\fP | |
64 | for additional information. | |
d60d9f65 SS |
65 | .SH RETURN VALUE |
66 | .LP | |
67 | .B readline | |
68 | returns the text of the line read. A blank line | |
69 | returns the empty string. If | |
70 | .B EOF | |
71 | is encountered while reading a line, and the line is empty, | |
72 | .B NULL | |
73 | is returned. If an | |
74 | .B EOF | |
75 | is read with a non\-empty line, it is | |
76 | treated as a newline. | |
77 | .SH NOTATION | |
78 | .LP | |
79 | An emacs-style notation is used to denote | |
80 | keystrokes. Control keys are denoted by C\-\fIkey\fR, e.g., C\-n | |
81 | means Control\-N. Similarly, | |
82 | .I meta | |
83 | keys are denoted by M\-\fIkey\fR, so M\-x means Meta\-X. (On keyboards | |
84 | without a | |
85 | .I meta | |
86 | key, M\-\fIx\fP means ESC \fIx\fP, i.e., press the Escape key | |
87 | then the | |
88 | .I x | |
89 | key. This makes ESC the \fImeta prefix\fP. | |
90 | The combination M\-C\-\fIx\fP means ESC\-Control\-\fIx\fP, | |
91 | or press the Escape key | |
92 | then hold the Control key while pressing the | |
93 | .I x | |
94 | key.) | |
95 | .PP | |
96 | Readline commands may be given numeric | |
97 | .IR arguments , | |
98 | which normally act as a repeat count. Sometimes, however, it is the | |
99 | sign of the argument that is significant. Passing a negative argument | |
100 | to a command that acts in the forward direction (e.g., \fBkill\-line\fP) | |
101 | causes that command to act in a backward direction. Commands whose | |
102 | behavior with arguments deviates from this are noted. | |
103 | .PP | |
104 | When a command is described as \fIkilling\fP text, the text | |
105 | deleted is saved for possible future retrieval | |
106 | (\fIyanking\fP). The killed text is saved in a | |
107 | \fIkill ring\fP. Consecutive kills cause the text to be | |
108 | accumulated into one unit, which can be yanked all at once. | |
109 | Commands which do not kill text separate the chunks of text | |
110 | on the kill ring. | |
111 | .SH INITIALIZATION FILE | |
112 | .LP | |
113 | Readline is customized by putting commands in an initialization | |
114 | file (the \fIinputrc\fP file). | |
115 | The name of this file is taken from the value of the | |
116 | .B INPUTRC | |
117 | environment variable. If that variable is unset, the default is | |
118 | .IR ~/.inputrc . | |
119 | When a program which uses the readline library starts up, the | |
120 | init file is read, and the key bindings and variables are set. | |
121 | There are only a few basic constructs allowed in the | |
122 | readline init file. Blank lines are ignored. | |
123 | Lines beginning with a \fB#\fP are comments. | |
124 | Lines beginning with a \fB$\fP indicate conditional constructs. | |
125 | Other lines denote key bindings and variable settings. | |
126 | Each program using this library may add its own commands | |
127 | and bindings. | |
128 | .PP | |
129 | For example, placing | |
130 | .RS | |
131 | .PP | |
132 | M\-Control\-u: universal\-argument | |

141 | would make M\-C\-u execute the readline command | |
142 | .IR universal\-argument . | |
143 | .PP | |
144 | The following symbolic character names are recognized while | |
145 | processing key bindings: | |
d60d9f65 SS |
146 | .IR DEL , |
147 | .IR ESC , | |
9255ee31 | 148 | .IR ESCAPE , |

d60d9f65 SS |
159 | In addition to command names, readline allows keys to be bound |
160 | to a string that is inserted when the key is pressed (a \fImacro\fP). | |
161 | .PP | |
162 | .SS Key Bindings | |
163 | .PP | |
164 | The syntax for controlling key bindings in the | |
165 | .I inputrc | |
166 | file is simple. All that is required is the name of the | |
167 | command or the text of a macro and a key sequence to which | |
168 | it should be bound. The name may be specified in one of two ways: | |
169 | as a symbolic key name, possibly with \fIMeta\-\fP or \fIControl\-\fP | |
170 | prefixes, or as a key sequence. | |
9255ee31 | 171 | .PP |
d60d9f65 SS |
172 | When using the form \fBkeyname\fP:\^\fIfunction-name\fP or \fImacro\fP, |
173 | .I keyname | |
174 | is the name of a key spelled out in English. For example: | |
175 | .sp | |
176 | .RS | |
177 | Control\-u: universal\-argument | |
178 | .br | |
179 | Meta\-Rubout: backward\-kill\-word | |
180 | .br | |
9255ee31 | 181 | Control\-o: "> output" |
d60d9f65 SS |
182 | .RE |
183 | .LP | |
184 | In the above example, | |
185 | .I C\-u | |
186 | is bound to the function | |
187 | .BR universal\-argument , | |
188 | .I M-DEL | |
189 | is bound to the function | |
190 | .BR backward\-kill\-word , | |
191 | and | |
192 | .I C\-o | |
193 | is bound to run the macro | |
194 | expressed on the right hand side (that is, to insert the text | |
9255ee31 EZ |
195 | .if t \f(CW> output\fP |
196 | .if n ``> output'' | |
d60d9f65 SS |
197 | into the line). |
198 | .PP | |
199 | In the second form, \fB"keyseq"\fP:\^\fIfunction\-name\fP or \fImacro\fP, | |
200 | .B keyseq | |
201 | differs from | |
202 | .B keyname | |
203 | above in that strings denoting | |
204 | an entire key sequence may be specified by placing the sequence | |
205 | within double quotes. Some GNU Emacs style key escapes can be | |
9255ee31 EZ |
206 | used, as in the following example, but the symbolic character names |
207 | are not recognized. | |

215 | .RE | |
216 | .PP | |
217 | In this example, | |
218 | .I C-u | |
219 | is again bound to the function | |
220 | .BR universal\-argument . | |
221 | .I "C-x C-r" | |
222 | is bound to the function | |
223 | .BR re\-read\-init\-file , | |

307 | .B \-o | |
308 | option to the | |

310 | builtin command. Other programs using this library provide | |
311 | similar mechanisms. The | |

313 | file may be edited and re-read if a program does not provide | |
314 | any other means to incorporate new bindings. | |
315 | .SS Variables | |
316 | .PP | |
317 | Readline has variables that can be used to further customize its | |
318 | behavior. A variable may be set in the | |

320 | file with a statement of the form | |
321 | .RS | |

332 | .PP | |
333 | .PD 0 | |
334 | .TP | |
335 | .B bell\-style (audible) | |
336 | Controls what happens when readline wants to ring the terminal bell. | |
337 | If set to \fBnone\fP, readline never rings the bell. If set to | |
338 | \fBvisible\fP, readline uses a visible bell if one is available. | |
339 | If set to \fBaudible\fP, readline attempts to ring the terminal's bell. | |
340 | .TP | |
341 | .B comment\-begin (``#'') | |
342 | The string that is inserted in \fBvi\fP mode when the | |
343 | .B insert\-comment | |
344 | command is executed. | |
345 | This command is bound to | |
346 | .B M\-# | |
347 | in emacs mode and to | |
348 | .B # | |
349 | in vi command mode. | |
350 | .TP | |
351 | .B completion\-ignore\-case (Off) | |
352 | If set to \fBOn\fP, readline performs filename matching and completion | |
353 | in a case\-insensitive fashion. | |
354 | .TP | |
355 | .B completion\-query\-items (100) | |
356 | This determines when the user is queried about viewing | |
357 | the number of possible completions | |
358 | generated by the \fBpossible\-completions\fP command. | |
359 | It may be set to any integer value greater than or equal to | |
360 | zero. If the number of possible completions is greater than | |
361 | or equal to the value of this variable, the user is asked whether | |
362 | or not he wishes to view them; otherwise they are simply listed | |
363 | on the terminal. | |
364 | .TP | |
365 | .B convert\-meta (On) | |
366 | If set to \fBOn\fP, readline will convert characters with the | |
367 | eighth bit set to an ASCII key sequence | |
9255ee31 | 368 | by stripping the eighth bit and prefixing it with an |
d60d9f65 SS |
369 | escape character (in effect, using escape as the \fImeta prefix\fP). |
370 | .TP | |
371 | .B disable\-completion (Off) | |
372 | If set to \fBOn\fP, readline will inhibit word completion. Completion | |
373 | characters will be inserted into the line as if they had been | |
374 | mapped to \fBself-insert\fP. | |
375 | .TP | |
376 | .B editing\-mode (emacs) | |
377 | Controls whether readline begins with a set of key bindings similar | |
9255ee31 | 378 | to emacs or vi. |
d60d9f65 SS |
379 | .B editing\-mode |
380 | can be set to either | |
381 | .B emacs | |
382 | or | |
383 | .BR vi . | |
384 | .TP | |
385 | .B enable\-keypad (Off) | |
386 | When set to \fBOn\fP, readline will try to enable the application | |
387 | keypad when it is called. Some systems need this to enable the | |
388 | arrow keys. | |
389 | .TP | |
390 | .B expand\-tilde (Off) | |
391 | If set to \fBon\fP, tilde expansion is performed when readline | |
392 | attempts word completion. | |
393 | .TP | |
9255ee31 EZ |
394 | .B history-preserve-point |
395 | If set to \fBon\fP, the history code attempts to place point at the | |
396 | same location on each history line retrived with \fBprevious-history\fP | |
397 | or \fBnext-history\fP. | |
398 | .TP | |
d60d9f65 SS |
399 | .B horizontal\-scroll\-mode (Off) |
400 | When set to \fBOn\fP, makes readline use a single line for display, | |
401 | scrolling the input horizontally on a single screen line when it | |
402 | becomes longer than the screen width rather than wrapping to a new line. | |
403 | .TP | |
c862e87b JM |
404 | .B input\-meta (Off) |
405 | If set to \fBOn\fP, readline will enable eight-bit input (that is, | |
9255ee31 | 406 | it will not clear the eighth bit in the characters it reads), |
c862e87b JM |
407 | regardless of what the terminal claims it can support. The name |
408 | .B meta\-flag | |
409 | is a synonym for this variable. | |
410 | .TP | |
9255ee31 | 411 | .B isearch\-terminators (``C\-[ C\-J'') |
c862e87b JM |
412 | The string of characters that should terminate an incremental |
413 | search without subsequently executing the character as a command. | |
414 | If this variable has not been given a value, the characters | |
415 | \fIESC\fP and \fIC\-J\fP will terminate an incremental search. | |
416 | .TP | |
d60d9f65 SS |
417 | .B keymap (emacs) |
418 | Set the current readline keymap. The set of legal keymap names is | |
419 | \fIemacs, emacs-standard, emacs-meta, emacs-ctlx, vi, vi-move, | |
420 | vi-command\fP, and | |
421 | .IR vi-insert . | |
422 | \fIvi\fP is equivalent to \fIvi-command\fP; \fIemacs\fP is | |
423 | equivalent to \fIemacs-standard\fP. The default value is | |
9255ee31 EZ |
424 | .IR emacs . |
425 | The value of | |
d60d9f65 SS |
426 | .B editing\-mode |
427 | also affects the default keymap. | |
428 | .TP | |
429 | .B mark\-directories (On) | |
9255ee31 | 430 | If set to \fBOn\fP, completed directory names have a slash |
d60d9f65 SS |
431 | appended. |
432 | .TP | |
433 | .B mark\-modified\-lines (Off) | |
434 | If set to \fBOn\fP, history lines that have been modified are displayed | |
435 | with a preceding asterisk (\fB*\fP). | |
436 | .TP | |
9255ee31 EZ |
437 | .B mark\-symlinked\-directories (Off) |
438 | If set to \fBOn\fP, completed names which are symbolic links to directories | |
439 | have a slash appended (subject to the value of | |
440 | \fBmark\-directories\fP). | |
441 | .TP | |
442 | .B match\-hidden\-files (On) | |
443 | This variable, when set to \fBOn\fP, causes readline to match files whose | |
444 | names begin with a `.' (hidden files) when performing filename | |
445 | completion, unless the leading `.' is | |
446 | supplied by the user in the filename to be completed. | |
447 | .TP | |
d60d9f65 SS |
448 | .B output\-meta (Off) |
449 | If set to \fBOn\fP, readline will display characters with the | |
450 | eighth bit set directly rather than as a meta-prefixed escape | |
451 | sequence. | |
452 | .TP | |
9255ee31 EZ |
453 | .B page\-completions (On) |
454 | If set to \fBOn\fP, readline uses an internal \fImore\fP-like pager | |
455 | to display a screenful of possible completions at a time. | |
456 | .TP | |
d60d9f65 SS |
457 | .B print\-completions\-horizontally (Off) |
458 | If set to \fBOn\fP, readline will display completions with matches | |
459 | sorted horizontally in alphabetical order, rather than down the screen. | |
460 | .TP | |
461 | .B show\-all\-if\-ambiguous (Off) | |
462 | This alters the default behavior of the completion functions. If | |
463 | set to | |
464 | .BR on , | |

473 | .SS Conditional Constructs | |
474 | .PP | |
475 | Readline implements a facility similar in spirit to the conditional | |
476 | compilation features of the C preprocessor which allows key | |
477 | bindings and variable settings to be performed as the result | |
478 | of tests. There are four parser directives used. | |
479 | .IP \fB$if\fP | |
480 | The | |
481 | .B $if | |
482 | construct allows bindings to be made based on the | |
483 | editing mode, the terminal being used, or the application using | |
484 | readline. The text of the test extends to the end of the line; | |
485 | no characters are required to isolate it. | |
486 | .RS | |
487 | .IP \fBmode\fP | |
488 | The \fBmode=\fP form of the \fB$if\fP directive is used to test | |
489 | whether readline is in emacs or vi mode. | |
490 | This may be used in conjunction | |
491 | with the \fBset keymap\fP command, for instance, to set bindings in | |
492 | the \fIemacs-standard\fP and \fIemacs-ctlx\fP keymaps only if | |
493 | readline is starting out in emacs mode. | |
494 | .IP \fBterm\fP | |
495 | The \fBterm=\fP form may be used to include terminal-specific | |
496 | key bindings, perhaps to bind the key sequences output by the | |
497 | terminal's function keys. The word on the right side of the | |
498 | .B = | |
499 | is tested against the full name of the terminal and the portion | |
500 | of the terminal name before the first \fB\-\fP. This allows | |
501 | .I sun | |
502 | to match both | |
503 | .I sun | |
504 | and | |
505 | .IR sun\-cmd , | |
506 | for instance. | |
507 | .IP \fBapplication\fP | |
508 | The \fBapplication\fP construct is used to include | |
509 | application-specific settings. Each program using the readline | |
510 | library sets the \fIapplication name\fP, and an initialization | |
511 | file can test for a particular value. | |
512 | This could be used to bind key sequences to functions useful for | |
513 | a specific program. For instance, the following command adds a | |
514 | key sequence that quotes the current or previous word in Bash: | |
515 | .sp 1 | |
516 | .RS | |
517 | .nf | |
9255ee31 | 518 | \fB$if\fP Bash |
d60d9f65 SS |
519 | # Quote the current or previous word |
520 | "\eC-xq": "\eeb\e"\eef\e"" | |
521 | \fB$endif\fP | |
522 | .fi | |
523 | .RE | |
524 | .RE | |
525 | .IP \fB$endif\fP | |
526 | This command, as seen in the previous example, terminates an | |
527 | \fB$if\fP command. | |
528 | .IP \fB$else\fP | |
529 | Commands in this branch of the \fB$if\fP directive are executed if | |
530 | the test fails. | |
531 | .IP \fB$include\fP | |
532 | This directive takes a single filename as an argument and reads commands | |
533 | and bindings from that file. For example, the following directive | |
534 | would read \fI/etc/inputrc\fP: | |
535 | .sp 1 | |
536 | .RS | |
537 | .nf | |
538 | \fB$include\fP \^ \fI/etc/inputrc\fP | |
539 | .fi | |
540 | .RE | |
541 | .SH SEARCHING | |
542 | .PP | |
543 | Readline provides commands for searching through the command history | |
544 | for lines containing a specified string. | |
545 | There are two search modes: | |
546 | .I incremental | |
547 | and | |
548 | .IR non-incremental . | |
549 | .PP | |
550 | Incremental searches begin before the user has finished typing the | |
551 | search string. | |
552 | As each character of the search string is typed, readline displays | |
553 | the next entry from the history matching the string typed so far. | |
554 | An incremental search requires only as many characters as needed to | |
555 | find the desired history entry. | |
9255ee31 EZ |
556 | To search backward in the history for a particular string, type |
557 | \fBC\-r\fP. Typing \fBC\-s\fP searches forward through the history. | |
558 | The characters present in the value of the \fBisearch-terminators\fP | |
c862e87b | 559 | variable are used to terminate an incremental search. |
9255ee31 EZ |
560 | If that variable has not been assigned a value the \fIEscape\fP and |
561 | \fBC\-J\fP characters will terminate an incremental search. | |
562 | \fBC\-G\fP will abort an incremental search and restore the original | |
d60d9f65 SS |
563 | line. |
564 | When the search is terminated, the history entry containing the | |
565 | search string becomes the current line. | |
9255ee31 EZ |
566 | .PP |
567 | To find other matching entries in the history list, type \fBC\-s\fP or | |
568 | \fBC\-r\fP as appropriate. | |
d60d9f65 SS |
569 | This will search backward or forward in the history for the next |
570 | line matching the search string typed so far. | |
571 | Any other key sequence bound to a readline command will terminate | |
572 | the search and execute that command. | |
9255ee31 | 573 | For instance, a newline will terminate the search and accept |
d60d9f65 | 574 | the line, thereby executing the command from the history list. |
9255ee31 EZ |
575 | A movement command will terminate the search, make the last line found |
576 | the current line, and begin editing. | |
d60d9f65 SS |
577 | .PP |
578 | Non-incremental searches read the entire search string before starting | |
579 | to search for matching history lines. The search string may be | |
580 | typed by the user or be part of the contents of the current line. | |
581 | .SH EDITING COMMANDS | |
582 | .PP | |
583 | The following is a list of the names of the commands and the default | |
584 | key sequences to which they are bound. | |
585 | Command names without an accompanying key sequence are unbound by default. | |
9255ee31 EZ |
586 | .PP |
587 | In the following descriptions, \fIpoint\fP refers to the current cursor | |
588 | position, and \fImark\fP refers to a cursor position saved by the | |
589 | \fBset\-mark\fP command. | |
590 | The text between the point and mark is referred to as the \fIregion\fP. | |

1000 | .SH DEFAULT KEY BINDINGS | |
1001 | .LP | |
1002 | The following is a list of the default emacs and vi bindings. | |
9255ee31 | 1003 | Characters with the eighth bit set are written as M\-<character>, and |
d60d9f65 SS |
1004 | are referred to as |
1005 | .I metafied | |
1006 | characters. | |
1007 | The printable ASCII characters not mentioned in the list of emacs | |
1008 | standard bindings are bound to the | |
9255ee31 | 1009 | .B self\-insert |
d60d9f65 SS |
1010 | function, which just inserts the given character into the input line. |
1011 | In vi insertion mode, all characters not specifically mentioned are | |
1012 | bound to | |
9255ee31 | 1013 | .BR self\-insert . |
d60d9f65 SS |
1014 | Characters assigned to signal generation by |
1015 | .IR stty (1) | |
1016 | or the terminal driver, such as C-Z or C-C, | |
1017 | retain that function. | |
9255ee31 EZ |
1018 | Upper and lower case metafied characters are bound to the same function in |
1019 | the emacs mode meta keymap. | |
d60d9f65 SS |
1020 | The remaining characters are unbound, which causes readline |
1021 | to ring the bell (subject to the setting of the | |
1022 | .B bell\-style | |
1023 | variable). | |
