| 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 |
| 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 |
| 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 | .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. |
| 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 |
| 133 | .RE |
| 134 | or |
| 135 | .RS |
| 136 | C\-Meta\-u: universal\-argument |
| 137 | .RE |
| 138 | .sp |
| 139 | into the |
| 140 | .I inputrc |
| 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: |
| 146 | .IR DEL , |
| 147 | .IR ESC , |
| 148 | .IR ESCAPE , |
| 149 | .IR LFD , |
| 150 | .IR NEWLINE , |
| 151 | .IR RET , |
| 152 | .IR RETURN , |
| 153 | .IR RUBOUT , |
| 154 | .IR SPACE , |
| 155 | .IR SPC , |
| 156 | and |
| 157 | .IR TAB . |
| 158 | .PP |
| 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. |
| 171 | .PP |
| 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 |
| 181 | Control\-o: "> output" |
| 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 |
| 195 | .if t \f(CW> output\fP |
| 196 | .if n ``> output'' |
| 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 |
| 206 | used, as in the following example, but the symbolic character names |
| 207 | are not recognized. |
| 208 | .sp |
| 209 | .RS |
| 210 | "\eC\-u": universal\-argument |
| 211 | .br |
| 212 | "\eC\-x\eC\-r": re\-read\-init\-file |
| 213 | .br |
| 214 | "\ee[11~": "Function Key 1" |
| 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 , |
| 224 | and |
| 225 | .I "ESC [ 1 1 ~" |
| 226 | is bound to insert the text |
| 227 | .if t \f(CWFunction Key 1\fP. |
| 228 | .if n ``Function Key 1''. |
| 229 | .PP |

| 287 | .TP |
| 288 | .B \ex\fIHH\fP |

| 290 | (one or two hex digits) |
| 291 | .RE |
| 292 | .PD |
| 293 | .PP |
| 294 | When entering the text of a macro, single or double quotes should |
| 295 | be used to indicate a macro definition. Unquoted text |
| 296 | is assumed to be a function name. |
| 297 | In the macro body, the backslash escapes described above are expanded. |
| 298 | Backslash will quote any other character in the macro text, |
| 299 | including " and '. |
| 300 | .PP |
| 301 | .B Bash |
| 302 | allows the current readline key bindings to be displayed or modified |
| 303 | with the |
| 304 | .B bind |
| 305 | builtin command. The editing mode may be switched during interactive |
| 306 | use by using the |
| 307 | .B \-o |
| 308 | option to the |
| 309 | .B set |
| 310 | builtin command. Other programs using this library provide |
| 311 | similar mechanisms. The |
| 312 | .I inputrc |
| 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 |
| 319 | .I inputrc |
| 320 | file with a statement of the form |
| 321 | .RS |
| 322 | .PP |
| 323 | \fBset\fP \fIvariable\-name\fP \fIvalue\fP |
| 324 | .RE |
| 325 | .PP |
| 326 | Except where noted, readline variables can take the values |
| 327 | .B On |
| 328 | or |
| 329 | .B Off |
| 330 | (without regard to case). |
| 331 | The variables and their default values are: |
| 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 |
| 368 | by stripping the eighth bit and prefixing it with an |
| 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 |
| 378 | to emacs or vi. |
| 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 |
| 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 |
| 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 |
| 404 | .B input\-meta (Off) |
| 405 | If set to \fBOn\fP, readline will enable eight-bit input (that is, |
| 406 | it will not clear the eighth bit in the characters it reads), |
| 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 |
| 411 | .B isearch\-terminators (``C\-[ C\-J'') |
| 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 |
| 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 |
| 424 | .IR emacs . |
| 425 | The value of |
| 426 | .B editing\-mode |
| 427 | also affects the default keymap. |
| 428 | .TP |
| 429 | .B mark\-directories (On) |
| 430 | If set to \fBOn\fP, completed directory names have a slash |
| 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 |
| 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 |
| 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 |
| 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 |
| 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 , |
| 465 | words which have more than one possible completion cause the |
| 466 | matches to be listed immediately instead of ringing the bell. |
| 467 | .TP |
| 468 | .B visible\-stats (Off) |
| 469 | If set to \fBOn\fP, a character denoting a file's type as reported |
| 470 | by \fIstat\fP(2) is appended to the filename when listing possible |
| 471 | completions. |
| 472 | .PD |
| 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 |

| 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 |
| 518 | \fB$if\fP Bash |
| 519 | # Quote the current or previous word |

| 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 |

| 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. |
| 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 |
| 559 | variable are used to terminate an incremental search. |
| 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 |
| 563 | line. |
| 564 | When the search is terminated, the history entry containing the |
| 565 | search string becomes the current line. |
| 566 | .PP |
| 567 | To find other matching entries in the history list, type \fBC\-s\fP or |
| 568 | \fBC\-r\fP as appropriate. |
| 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. |
| 573 | For instance, a newline will terminate the search and accept |
| 574 | the line, thereby executing the command from the history list. |
| 575 | A movement command will terminate the search, make the last line found |
| 576 | the current line, and begin editing. |
| 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. |

| 1000 | .SH DEFAULT KEY BINDINGS |
| 1001 | .LP |
| 1002 | The following is a list of the default emacs and vi bindings. |
| 1003 | Characters with the eighth bit set are written as M\-<character>, and |
| 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 |
| 1009 | .B self\-insert |
| 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 |
| 1013 | .BR self\-insert . |
| 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. |
| 1018 | Upper and lower case metafied characters are bound to the same function in |
| 1019 | the emacs mode meta keymap. |
| 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). |
