40 | .SH DESCRIPTION | |
41 | .LP | |
42 | .B readline | |
43 | will read a line from the terminal | |
44 | and return it, using | |
45 | .B prompt | |
46 | as a prompt. If | |
47 | .B prompt | |
48 | is null, no prompt is issued. The line returned is allocated with | |
49 | .IR malloc (3), | |
50 | so the caller must free it when finished. The line returned | |
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. | |
60 | .SH RETURN VALUE | |
61 | .LP | |
62 | .B readline | |
63 | returns the text of the line read. A blank line | |
64 | returns the empty string. If | |
65 | .B EOF | |
66 | is encountered while reading a line, and the line is empty, | |
67 | .B NULL | |
68 | is returned. If an | |
69 | .B EOF | |
70 | is read with a non\-empty line, it is | |
71 | treated as a newline. | |
72 | .SH NOTATION | |
73 | .LP | |
74 | An emacs-style notation is used to denote | |
75 | keystrokes. Control keys are denoted by C\-\fIkey\fR, e.g., C\-n | |
76 | means Control\-N. Similarly, | |
77 | .I meta | |
78 | keys are denoted by M\-\fIkey\fR, so M\-x means Meta\-X. (On keyboards | |
79 | without a | |
80 | .I meta | |
81 | key, M\-\fIx\fP means ESC \fIx\fP, i.e., press the Escape key | |
82 | then the | |
83 | .I x | |
84 | key. This makes ESC the \fImeta prefix\fP. | |
85 | The combination M\-C\-\fIx\fP means ESC\-Control\-\fIx\fP, | |
86 | or press the Escape key | |
87 | then hold the Control key while pressing the | |
88 | .I x | |
89 | key.) | |
90 | .PP | |
91 | Readline commands may be given numeric | |
92 | .IR arguments , | |
93 | which normally act as a repeat count. Sometimes, however, it is the | |
94 | sign of the argument that is significant. Passing a negative argument | |
95 | to a command that acts in the forward direction (e.g., \fBkill\-line\fP) | |
96 | causes that command to act in a backward direction. Commands whose | |
97 | behavior with arguments deviates from this are noted. | |
98 | .PP | |
99 | When a command is described as \fIkilling\fP text, the text | |
100 | deleted is saved for possible future retrieval | |
101 | (\fIyanking\fP). The killed text is saved in a | |
102 | \fIkill ring\fP. Consecutive kills cause the text to be | |
103 | accumulated into one unit, which can be yanked all at once. | |
104 | Commands which do not kill text separate the chunks of text | |
105 | on the kill ring. | |
106 | .SH INITIALIZATION FILE | |
107 | .LP | |
108 | Readline is customized by putting commands in an initialization | |
109 | file (the \fIinputrc\fP file). | |
110 | The name of this file is taken from the value of the | |
111 | .B INPUTRC | |
112 | environment variable. If that variable is unset, the default is | |
113 | .IR ~/.inputrc . | |
114 | When a program which uses the readline library starts up, the | |
115 | init file is read, and the key bindings and variables are set. | |
116 | There are only a few basic constructs allowed in the | |
117 | readline init file. Blank lines are ignored. | |
118 | Lines beginning with a \fB#\fP are comments. | |
119 | Lines beginning with a \fB$\fP indicate conditional constructs. | |
120 | Other lines denote key bindings and variable settings. | |
121 | Each program using this library may add its own commands | |
122 | and bindings. | |
123 | .PP | |
124 | For example, placing | |
125 | .RS | |
126 | .PP | |
127 | M\-Control\-u: universal\-argument | |
128 | .RE | |
129 | or | |
130 | .RS | |
131 | C\-Meta\-u: universal\-argument | |
132 | .RE | |
133 | into the | |
134 | .I inputrc | |
135 | would make M\-C\-u execute the readline command | |
136 | .IR universal\-argument . | |
137 | .PP | |
138 | The following symbolic character names are recognized while | |
139 | processing key bindings: | |
140 | .IR RUBOUT , | |
141 | .IR DEL , | |
142 | .IR ESC , | |
143 | .IR LFD , | |
144 | .IR NEWLINE , | |
145 | .IR RET , | |
146 | .IR RETURN , | |
147 | .IR SPC , | |
148 | .IR SPACE , | |
149 | and | |
150 | .IR TAB . | |
151 | In addition to command names, readline allows keys to be bound | |
152 | to a string that is inserted when the key is pressed (a \fImacro\fP). | |
153 | .PP | |
154 | .SS Key Bindings | |
155 | .PP | |
156 | The syntax for controlling key bindings in the | |
157 | .I inputrc | |
158 | file is simple. All that is required is the name of the | |
159 | command or the text of a macro and a key sequence to which | |
160 | it should be bound. The name may be specified in one of two ways: | |
161 | as a symbolic key name, possibly with \fIMeta\-\fP or \fIControl\-\fP | |
162 | prefixes, or as a key sequence. | |
163 | When using the form \fBkeyname\fP:\^\fIfunction-name\fP or \fImacro\fP, | |
164 | .I keyname | |
165 | is the name of a key spelled out in English. For example: | |
166 | .sp | |
167 | .RS | |
168 | Control\-u: universal\-argument | |
169 | .br | |
170 | Meta\-Rubout: backward\-kill\-word | |
171 | .br | |
172 | Control\-o: ">&output" | |
173 | .RE | |
174 | .LP | |
175 | In the above example, | |
176 | .I C\-u | |
177 | is bound to the function | |
178 | .BR universal\-argument , | |
179 | .I M-DEL | |
180 | is bound to the function | |
181 | .BR backward\-kill\-word , | |
182 | and | |
183 | .I C\-o | |
184 | is bound to run the macro | |
185 | expressed on the right hand side (that is, to insert the text | |
186 | .I >&output | |
187 | into the line). | |
188 | .PP | |
189 | In the second form, \fB"keyseq"\fP:\^\fIfunction\-name\fP or \fImacro\fP, | |
190 | .B keyseq | |
191 | differs from | |
192 | .B keyname | |
193 | above in that strings denoting | |
194 | an entire key sequence may be specified by placing the sequence | |
195 | within double quotes. Some GNU Emacs style key escapes can be | |
196 | used, as in the following example. | |
197 | .sp | |
198 | .RS | |
199 | "\eC\-u": universal\-argument | |
200 | .br | |
201 | "\eC\-x\eC\-r": re\-read\-init\-file | |
202 | .br | |
203 | "\ee[11~": "Function Key 1" | |
204 | .RE | |
205 | .PP | |
206 | In this example, | |
207 | .I C-u | |
208 | is again bound to the function | |
209 | .BR universal\-argument . | |
210 | .I "C-x C-r" | |
211 | is bound to the function | |
212 | .BR re\-read\-init\-file , | |
213 | and | |
214 | .I "ESC [ 1 1 ~" | |
215 | is bound to insert the text | |
216 | .BR "Function Key 1" . | |

277 | .RE | |
278 | .PD | |
279 | .PP | |
280 | When entering the text of a macro, single or double quotes should | |
281 | be used to indicate a macro definition. Unquoted text | |
282 | is assumed to be a function name. | |
283 | In the macro body, the backslash escapes described above are expanded. | |
284 | Backslash will quote any other character in the macro text, | |
285 | including " and '. | |
286 | .PP | |
287 | .B Bash | |
288 | allows the current readline key bindings to be displayed or modified | |
289 | with the | |
290 | .B bind | |
291 | builtin command. The editing mode may be switched during interactive | |
292 | use by using the | |
293 | .B \-o | |
294 | option to the | |
295 | .B set | |
296 | builtin command. Other programs using this library provide | |
297 | similar mechanisms. The | |
298 | .I inputrc | |
299 | file may be edited and re-read if a program does not provide | |
300 | any other means to incorporate new bindings. | |
301 | .SS Variables | |
302 | .PP | |
303 | Readline has variables that can be used to further customize its | |
304 | behavior. A variable may be set in the | |
305 | .I inputrc | |
306 | file with a statement of the form | |
307 | .RS | |
308 | .PP | |
309 | \fBset\fP \fIvariable\-name\fP \fIvalue\fP | |
310 | .RE | |
311 | .PP | |
312 | Except where noted, readline variables can take the values | |
313 | .B On | |
314 | or | |
315 | .BR Off . | |
316 | The variables and their default values are: | |
317 | .PP | |
318 | .PD 0 | |
319 | .TP | |
320 | .B bell\-style (audible) | |
321 | Controls what happens when readline wants to ring the terminal bell. | |
322 | If set to \fBnone\fP, readline never rings the bell. If set to | |
323 | \fBvisible\fP, readline uses a visible bell if one is available. | |
324 | If set to \fBaudible\fP, readline attempts to ring the terminal's bell. | |
325 | .TP | |
326 | .B comment\-begin (``#'') | |
327 | The string that is inserted in \fBvi\fP mode when the | |
328 | .B insert\-comment | |
329 | command is executed. | |
330 | This command is bound to | |
331 | .B M\-# | |
332 | in emacs mode and to | |
333 | .B # | |
334 | in vi command mode. | |
335 | .TP | |
336 | .B completion\-ignore\-case (Off) | |
337 | If set to \fBOn\fP, readline performs filename matching and completion | |
338 | in a case\-insensitive fashion. | |
339 | .TP | |
340 | .B completion\-query\-items (100) | |
341 | This determines when the user is queried about viewing | |
342 | the number of possible completions | |
343 | generated by the \fBpossible\-completions\fP command. | |
344 | It may be set to any integer value greater than or equal to | |
345 | zero. If the number of possible completions is greater than | |
346 | or equal to the value of this variable, the user is asked whether | |
347 | or not he wishes to view them; otherwise they are simply listed | |
348 | on the terminal. | |
349 | .TP | |
350 | .B convert\-meta (On) | |
351 | If set to \fBOn\fP, readline will convert characters with the | |
352 | eighth bit set to an ASCII key sequence | |
353 | by stripping the eighth bit and prepending an | |
354 | escape character (in effect, using escape as the \fImeta prefix\fP). | |
355 | .TP | |
356 | .B disable\-completion (Off) | |
357 | If set to \fBOn\fP, readline will inhibit word completion. Completion | |
358 | characters will be inserted into the line as if they had been | |
359 | mapped to \fBself-insert\fP. | |
360 | .TP | |
361 | .B editing\-mode (emacs) | |
362 | Controls whether readline begins with a set of key bindings similar | |
363 | to \fIemacs\fP or \fIvi\fP. | |
364 | .B editing\-mode | |
365 | can be set to either | |
366 | .B emacs | |
367 | or | |
368 | .BR vi . | |
369 | .TP | |
370 | .B enable\-keypad (Off) | |
371 | When set to \fBOn\fP, readline will try to enable the application | |
372 | keypad when it is called. Some systems need this to enable the | |
373 | arrow keys. | |
374 | .TP | |
375 | .B expand\-tilde (Off) | |
376 | If set to \fBon\fP, tilde expansion is performed when readline | |
377 | attempts word completion. | |
378 | .TP | |
379 | .B horizontal\-scroll\-mode (Off) | |
380 | When set to \fBOn\fP, makes readline use a single line for display, | |
381 | scrolling the input horizontally on a single screen line when it | |
382 | becomes longer than the screen width rather than wrapping to a new line. | |
383 | .TP | |
c862e87b JM |
384 | .B input\-meta (Off) |
385 | If set to \fBOn\fP, readline will enable eight-bit input (that is, | |
386 | it will not strip the high bit from the characters it reads), | |
387 | regardless of what the terminal claims it can support. The name | |
388 | .B meta\-flag | |
389 | is a synonym for this variable. | |
390 | .TP | |
391 | .B isearch\-terminators (``C\-[C\-J'') | |
392 | The string of characters that should terminate an incremental | |
393 | search without subsequently executing the character as a command. | |
394 | If this variable has not been given a value, the characters | |
395 | \fIESC\fP and \fIC\-J\fP will terminate an incremental search. | |
396 | .TP | |
d60d9f65 SS |
397 | .B keymap (emacs) |
398 | Set the current readline keymap. The set of legal keymap names is | |
399 | \fIemacs, emacs-standard, emacs-meta, emacs-ctlx, vi, vi-move, | |
400 | vi-command\fP, and | |
401 | .IR vi-insert . | |
402 | \fIvi\fP is equivalent to \fIvi-command\fP; \fIemacs\fP is | |
403 | equivalent to \fIemacs-standard\fP. The default value is | |
404 | .IR emacs ; | |
405 | the value of | |
406 | .B editing\-mode | |
407 | also affects the default keymap. | |
408 | .TP | |
409 | .B mark\-directories (On) | |
410 | If set to \fBOn\fP, complete<d directory names have a slash | |
411 | appended. | |
412 | .TP | |
413 | .B mark\-modified\-lines (Off) | |
414 | If set to \fBOn\fP, history lines that have been modified are displayed | |
415 | with a preceding asterisk (\fB*\fP). | |
416 | .TP | |
d60d9f65 SS |
417 | .B output\-meta (Off) |
418 | If set to \fBOn\fP, readline will display characters with the | |
419 | eighth bit set directly rather than as a meta-prefixed escape | |
420 | sequence. | |
421 | .TP | |
422 | .B print\-completions\-horizontally (Off) | |
423 | If set to \fBOn\fP, readline will display completions with matches | |
424 | sorted horizontally in alphabetical order, rather than down the screen. | |
425 | .TP | |
426 | .B show\-all\-if\-ambiguous (Off) | |
427 | This alters the default behavior of the completion functions. If | |
428 | set to | |
429 | .BR on , | |
430 | words which have more than one possible completion cause the | |
431 | matches to be listed immediately instead of ringing the bell. | |
432 | .TP | |
433 | .B visible\-stats (Off) | |
434 | If set to \fBOn\fP, a character denoting a file's type as reported | |
435 | by \fBstat\fP(2) is appended to the filename when listing possible | |
436 | completions. | |
437 | .PD | |
438 | .SS Conditional Constructs | |
439 | .PP | |
440 | Readline implements a facility similar in spirit to the conditional | |
441 | compilation features of the C preprocessor which allows key | |
442 | bindings and variable settings to be performed as the result | |
443 | of tests. There are four parser directives used. | |
444 | .IP \fB$if\fP | |
445 | The | |
446 | .B $if | |
447 | construct allows bindings to be made based on the | |
448 | editing mode, the terminal being used, or the application using | |
449 | readline. The text of the test extends to the end of the line; | |
450 | no characters are required to isolate it. | |
451 | .RS | |
452 | .IP \fBmode\fP | |
453 | The \fBmode=\fP form of the \fB$if\fP directive is used to test | |
454 | whether readline is in emacs or vi mode. | |
455 | This may be used in conjunction | |
456 | with the \fBset keymap\fP command, for instance, to set bindings in | |
457 | the \fIemacs-standard\fP and \fIemacs-ctlx\fP keymaps only if | |
458 | readline is starting out in emacs mode. | |
459 | .IP \fBterm\fP | |
460 | The \fBterm=\fP form may be used to include terminal-specific | |
461 | key bindings, perhaps to bind the key sequences output by the | |
462 | terminal's function keys. The word on the right side of the | |
463 | .B = | |
464 | is tested against the full name of the terminal and the portion | |
465 | of the terminal name before the first \fB\-\fP. This allows | |
466 | .I sun | |
467 | to match both | |
468 | .I sun | |
469 | and | |
470 | .IR sun\-cmd , | |
471 | for instance. | |
472 | .IP \fBapplication\fP | |
473 | The \fBapplication\fP construct is used to include | |
474 | application-specific settings. Each program using the readline | |
475 | library sets the \fIapplication name\fP, and an initialization | |
476 | file can test for a particular value. | |
477 | This could be used to bind key sequences to functions useful for | |
478 | a specific program. For instance, the following command adds a | |
479 | key sequence that quotes the current or previous word in Bash: | |
480 | .sp 1 | |
481 | .RS | |
482 | .nf | |
483 | \fB$if\fP bash | |
484 | # Quote the current or previous word | |
485 | "\eC-xq": "\eeb\e"\eef\e"" | |
486 | \fB$endif\fP | |
487 | .fi | |
488 | .RE | |
489 | .RE | |
490 | .IP \fB$endif\fP | |
491 | This command, as seen in the previous example, terminates an | |
492 | \fB$if\fP command. | |
493 | .IP \fB$else\fP | |
494 | Commands in this branch of the \fB$if\fP directive are executed if | |
495 | the test fails. | |
496 | .IP \fB$include\fP | |
497 | This directive takes a single filename as an argument and reads commands | |
498 | and bindings from that file. For example, the following directive | |

506 | .SH SEARCHING | |
507 | .PP | |
508 | Readline provides commands for searching through the command history | |
509 | for lines containing a specified string. | |
510 | There are two search modes: | |
511 | .I incremental | |
512 | and | |
513 | .IR non-incremental . | |
514 | .PP | |
515 | Incremental searches begin before the user has finished typing the | |
516 | search string. | |
517 | As each character of the search string is typed, readline displays | |
518 | the next entry from the history matching the string typed so far. | |
519 | An incremental search requires only as many characters as needed to | |
520 | find the desired history entry. | |
c862e87b JM |
521 | The characters present in the value of the \fIisearch-terminators\fP |
522 | variable are used to terminate an incremental search. | |
523 | If that variable has not been assigned a value the Escape and | |
524 | Control-J characters will terminate an incremental search. | |
d60d9f65 SS |
525 | Control-G will abort an incremental search and restore the original |
526 | line. | |
527 | When the search is terminated, the history entry containing the | |
528 | search string becomes the current line. | |
529 | To find other matching entries in the history list, type Control-S or | |
530 | Control-R as appropriate. | |
531 | This will search backward or forward in the history for the next | |
532 | line matching the search string typed so far. | |
533 | Any other key sequence bound to a readline command will terminate | |
534 | the search and execute that command. | |
535 | For instance, a \fInewline\fP will terminate the search and accept | |
536 | the line, thereby executing the command from the history list. | |
537 | .PP | |
538 | Non-incremental searches read the entire search string before starting | |
539 | to search for matching history lines. The search string may be | |
540 | typed by the user or be part of the contents of the current line. | |
541 | .SH EDITING COMMANDS | |
542 | .PP | |
543 | The following is a list of the names of the commands and the default | |
544 | key sequences to which they are bound. | |

806 | Similar to \fBcomplete\fP, but replaces the word to be completed | |
807 | with a single match from the list of possible completions. | |
808 | Repeated execution of \fBmenu\-complete\fP steps through the list | |
809 | of possible completions, inserting each match in turn. | |
810 | At the end of the list of completions, the bell is rung and the | |

938 | The printable ASCII characters not mentioned in the list of emacs | |
939 | standard bindings are bound to the | |

942 | In vi insertion mode, all characters not specifically mentioned are | |
943 | bound to | |

945 | Characters assigned to signal generation by | |

948 | retain that function. | |

950 | .I metafied | |
951 | characters are bound to the same function in the emacs mode | |
952 | meta keymap. | |
