22 | r\bre\bea\bad\bdl\bli\bin\bne\be will read a line from the terminal and return it, | |
23 | using p\bpr\bro\bom\bmp\bpt\bt as a prompt. If p\bpr\bro\bom\bmp\bpt\bt is null, no prompt is | |
24 | issued. The line returned is allocated with _\bm_\ba_\bl_\bl_\bo_\bc(3), so | |
25 | the caller must free it when finished. The line returned | |
26 | has the final newline removed, so only the text of the | |
27 | line remains. | |
28 | ||
29 | r\bre\bea\bad\bdl\bli\bin\bne\be offers editing capabilities while the user is | |
30 | entering the line. By default, the line editing commands | |
31 | are similar to those of emacs. A vi-style line editing | |
32 | interface is also available. | |

35 | r\bre\bea\bad\bdl\bli\bin\bne\be returns the text of the line read. A blank line | |
36 | returns the empty string. If E\bEO\bOF\bF is encountered while | |
37 | reading a line, and the line is empty, N\bNU\bUL\bLL\bL is returned. | |
38 | If an E\bEO\bOF\bF is read with a non-empty line, it is treated as | |
39 | a newline. | |

42 | An emacs-style notation is used to denote keystrokes. | |
43 | Control keys are denoted by C-_\bk_\be_\by, e.g., C-n means Con- | |
44 | trol-N. Similarly, _\bm_\be_\bt_\ba keys are denoted by M-_\bk_\be_\by, so M-x | |
45 | means Meta-X. (On keyboards without a _\bm_\be_\bt_\ba key, M-_\bx means | |
46 | ESC _\bx, i.e., press the Escape key then the _\bx key. This | |
47 | makes ESC the _\bm_\be_\bt_\ba _\bp_\br_\be_\bf_\bi_\bx. The combination M-C-_\bx means | |
48 | ESC-Control-_\bx, or press the Escape key then hold the Con- | |
49 | trol key while pressing the _\bx key.) | |
50 | ||
51 | Readline commands may be given numeric _\ba_\br_\bg_\bu_\bm_\be_\bn_\bt_\bs, which | |
52 | normally act as a repeat count. Sometimes, however, it is | |
53 | the sign of the argument that is significant. Passing a | |
54 | negative argument to a command that acts in the forward | |
55 | direction (e.g., k\bki\bil\bll\bl-\b-l\bli\bin\bne\be) causes that command to act in | |
56 | a backward direction. Commands whose behavior with argu- | |
57 | ments deviates from this are noted. | |
58 | ||
59 | When a command is described as _\bk_\bi_\bl_\bl_\bi_\bn_\bg text, the text | |
60 | deleted is saved for possible future retrieval (_\by_\ba_\bn_\bk_\bi_\bn_\bg). | |

73 | The killed text is saved in a _\bk_\bi_\bl_\bl _\br_\bi_\bn_\bg. Consecutive | |
74 | kills cause the text to be accumulated into one unit, | |
75 | which can be yanked all at once. Commands which do not | |
76 | kill text separate the chunks of text on the kill ring. | |

79 | Readline is customized by putting commands in an initial- | |
80 | ization file (the _\bi_\bn_\bp_\bu_\bt_\br_\bc file). The name of this file is | |
81 | taken from the value of the I\bIN\bNP\bPU\bUT\bTR\bRC\bC environment variable. | |
82 | If that variable is unset, the default is _\b~_\b/_\b._\bi_\bn_\bp_\bu_\bt_\br_\bc. | |
83 | When a program which uses the readline library starts up, | |
84 | the init file is read, and the key bindings and variables | |
85 | are set. There are only a few basic constructs allowed in | |
86 | the readline init file. Blank lines are ignored. Lines | |
87 | beginning with a #\b# are comments. Lines beginning with a $\b$ | |
88 | indicate conditional constructs. Other lines denote key | |
89 | bindings and variable settings. Each program using this | |
90 | library may add its own commands and bindings. | |
91 | ||
92 | For example, placing | |
93 | ||
94 | M-Control-u: universal-argument | |
95 | or | |
96 | C-Meta-u: universal-argument | |
97 | into the _\bi_\bn_\bp_\bu_\bt_\br_\bc would make M-C-u execute the readline | |
98 | command _\bu_\bn_\bi_\bv_\be_\br_\bs_\ba_\bl_\b-_\ba_\br_\bg_\bu_\bm_\be_\bn_\bt. | |
99 | ||
100 | The following symbolic character names are recognized | |
101 | while processing key bindings: _\bR_\bU_\bB_\bO_\bU_\bT, _\bD_\bE_\bL, _\bE_\bS_\bC, _\bL_\bF_\bD, _\bN_\bE_\bW_\b- | |
102 | _\bL_\bI_\bN_\bE, _\bR_\bE_\bT, _\bR_\bE_\bT_\bU_\bR_\bN, _\bS_\bP_\bC, _\bS_\bP_\bA_\bC_\bE, and _\bT_\bA_\bB. In addition to | |
103 | command names, readline allows keys to be bound to a | |
104 | string that is inserted when the key is pressed (a _\bm_\ba_\bc_\br_\bo). | |
105 | ||

108 | The syntax for controlling key bindings in the _\bi_\bn_\bp_\bu_\bt_\br_\bc | |
109 | file is simple. All that is required is the name of the | |
110 | command or the text of a macro and a key sequence to which | |
111 | it should be bound. The name may be specified in one of | |
112 | two ways: as a symbolic key name, possibly with _\bM_\be_\bt_\ba_\b- or | |
113 | _\bC_\bo_\bn_\bt_\br_\bo_\bl_\b- prefixes, or as a key sequence. When using the | |
114 | form k\bke\bey\byn\bna\bam\bme\be:_\bf_\bu_\bn_\bc_\bt_\bi_\bo_\bn_\b-_\bn_\ba_\bm_\be or _\bm_\ba_\bc_\br_\bo, _\bk_\be_\by_\bn_\ba_\bm_\be is the name | |
115 | of a key spelled out in English. For example: | |
116 | ||
117 | Control-u: universal-argument | |
118 | Meta-Rubout: backward-kill-word | |
119 | Control-o: ">&output" | |
120 | ||
121 | In the above example, _\bC_\b-_\bu is bound to the function u\bun\bni\biv\bve\ber\br-\b- | |
122 | s\bsa\bal\bl-\b-a\bar\brg\bgu\bum\bme\ben\bnt\bt, _\bM_\b-_\bD_\bE_\bL is bound to the function b\bba\bac\bck\bk-\b- | |
123 | w\bwa\bar\brd\bd-\b-k\bki\bil\bll\bl-\b-w\bwo\bor\brd\bd, and _\bC_\b-_\bo is bound to run the macro | |
124 | expressed on the right hand side (that is, to insert the | |
125 | text _\b>_\b&_\bo_\bu_\bt_\bp_\bu_\bt into the line). | |

139 | In the second form, "\b"k\bke\bey\bys\bse\beq\bq"\b":_\bf_\bu_\bn_\bc_\bt_\bi_\bo_\bn_\b-_\bn_\ba_\bm_\be or _\bm_\ba_\bc_\br_\bo, k\bke\bey\by-\b- | |
140 | s\bse\beq\bq differs from k\bke\bey\byn\bna\bam\bme\be above in that strings denoting an | |
141 | entire key sequence may be specified by placing the | |
142 | sequence within double quotes. Some GNU Emacs style key | |
143 | escapes can be used, as in the following example. | |
144 | ||
145 | "\C-u": universal-argument | |
146 | "\C-x\C-r": re-read-init-file | |
147 | "\e[11~": "Function Key 1" | |
148 | ||
149 | In this example, _\bC_\b-_\bu is again bound to the function u\bun\bni\bi-\b- | |
150 | v\bve\ber\brs\bsa\bal\bl-\b-a\bar\brg\bgu\bum\bme\ben\bnt\bt. _\bC_\b-_\bx _\bC_\b-_\br is bound to the function | |
151 | r\bre\be-\b-r\bre\bea\bad\bd-\b-i\bin\bni\bit\bt-\b-f\bfi\bil\ble\be, and _\bE_\bS_\bC _\b[ _\b1 _\b1 _\b~ is bound to insert the | |
152 | text F\bFu\bun\bnc\bct\bti\bio\bon\bn K\bKe\bey\by 1\b1. The full set of GNU Emacs style | |
153 | escape sequences is | |
154 | \\b\C\bC-\b- control prefix | |
155 | \\b\M\bM-\b- meta prefix | |
156 | \\b\e\be an escape character | |
157 | \\b\\\b\ backslash | |
158 | \\b\"\b" literal " | |
159 | \\b\'\b' literal ' | |
160 | ||
161 | In addition to the GNU Emacs style escape sequences, a | |
162 | second set of backslash escapes is available: | |
163 | \\b\a\ba alert (bell) | |
164 | \\b\b\bb backspace | |
165 | \\b\d\bd delete | |
166 | \\b\f\bf form feed | |
167 | \\b\n\bn newline | |
168 | \\b\r\br carriage return | |
169 | \\b\t\bt horizontal tab | |
170 | \\b\v\bv vertical tab | |
171 | \\b\_\bn_\bn_\bn the character whose ASCII code is the octal | |
172 | value _\bn_\bn_\bn (one to three digits) | |
173 | \\b\x\bx_\bn_\bn_\bn the character whose ASCII code is the hex- | |
174 | adecimal value _\bn_\bn_\bn (one to three digits) | |
175 | ||
176 | When entering the text of a macro, single or double quotes | |
177 | should be used to indicate a macro definition. Unquoted | |
178 | text is assumed to be a function name. In the macro body, | |
179 | the backslash escapes described above are expanded. Back- | |
180 | slash will quote any other character in the macro text, | |
181 | including " and '. | |
182 | ||
183 | B\bBa\bas\bsh\bh allows the current readline key bindings to be dis- | |
184 | played or modified with the b\bbi\bin\bnd\bd builtin command. The | |
185 | editing mode may be switched during interactive use by | |
186 | using the -\b-o\bo option to the s\bse\bet\bt builtin command. Other | |
187 | programs using this library provide similar mechanisms. | |
188 | The _\bi_\bn_\bp_\bu_\bt_\br_\bc file may be edited and re-read if a program | |
189 | does not provide any other means to incorporate new bind- | |
190 | ings. | |

206 | Readline has variables that can be used to further cus- | |
207 | tomize its behavior. A variable may be set in the _\bi_\bn_\bp_\bu_\bt_\br_\bc | |
208 | file with a statement of the form | |
209 | ||
210 | s\bse\bet\bt _\bv_\ba_\br_\bi_\ba_\bb_\bl_\be_\b-_\bn_\ba_\bm_\be _\bv_\ba_\bl_\bu_\be | |
211 | ||
212 | Except where noted, readline variables can take the values | |
213 | O\bOn\bn or O\bOf\bff\bf. The variables and their default values are: | |
214 | ||
215 | b\bbe\bel\bll\bl-\b-s\bst\bty\byl\ble\be (\b(a\bau\bud\bdi\bib\bbl\ble\be)\b) | |
216 | Controls what happens when readline wants to ring | |
217 | the terminal bell. If set to n\bno\bon\bne\be, readline never | |
218 | rings the bell. If set to v\bvi\bis\bsi\bib\bbl\ble\be, readline uses a | |
219 | visible bell if one is available. If set to a\bau\bud\bdi\bi-\b- | |
220 | b\bbl\ble\be, readline attempts to ring the terminal's bell. | |
221 | c\bco\bom\bmm\bme\ben\bnt\bt-\b-b\bbe\beg\bgi\bin\bn (\b(`\b``\b`#\b#'\b''\b')\b) | |
222 | The string that is inserted in v\bvi\bi mode when the | |
223 | i\bin\bns\bse\ber\brt\bt-\b-c\bco\bom\bmm\bme\ben\bnt\bt command is executed. This command | |
224 | is bound to M\bM-\b-#\b# in emacs mode and to #\b# in vi com- | |
225 | mand mode. | |
226 | c\bco\bom\bmp\bpl\ble\bet\bti\bio\bon\bn-\b-i\big\bgn\bno\bor\bre\be-\b-c\bca\bas\bse\be (\b(O\bOf\bff\bf)\b) | |
227 | If set to O\bOn\bn, readline performs filename matching | |
228 | and completion in a case-insensitive fashion. | |
229 | c\bco\bom\bmp\bpl\ble\bet\bti\bio\bon\bn-\b-q\bqu\bue\ber\bry\by-\b-i\bit\bte\bem\bms\bs (\b(1\b10\b00\b0)\b) | |
230 | This determines when the user is queried about | |
231 | viewing the number of possible completions gener- | |
232 | ated by the p\bpo\bos\bss\bsi\bib\bbl\ble\be-\b-c\bco\bom\bmp\bpl\ble\bet\bti\bio\bon\bns\bs command. It may | |
233 | be set to any integer value greater than or equal | |
234 | to zero. If the number of possible completions is | |
235 | greater than or equal to the value of this vari- | |
236 | able, the user is asked whether or not he wishes to | |
237 | view them; otherwise they are simply listed on the | |
238 | terminal. | |
239 | c\bco\bon\bnv\bve\ber\brt\bt-\b-m\bme\bet\bta\ba (\b(O\bOn\bn)\b) | |
240 | If set to O\bOn\bn, readline will convert characters with | |
241 | the eighth bit set to an ASCII key sequence by | |
242 | stripping the eighth bit and prepending an escape | |
243 | character (in effect, using escape as the _\bm_\be_\bt_\ba _\bp_\br_\be_\b- | |
244 | _\bf_\bi_\bx). | |

247 | tion. Completion characters will be inserted into | |
248 | the line as if they had been mapped to s\bse\bel\blf\bf-\b-i\bin\bns\bse\ber\brt\bt. | |
249 | e\bed\bdi\bit\bti\bin\bng\bg-\b-m\bmo\bod\bde\be (\b(e\bem\bma\bac\bcs\bs)\b) | |
250 | Controls whether readline begins with a set of key | |
251 | bindings similar to _\be_\bm_\ba_\bc_\bs or _\bv_\bi. e\bed\bdi\bit\bti\bin\bng\bg-\b-m\bmo\bod\bde\be can | |

277 | k\bke\bey\bym\bma\bap\bp (\b(e\bem\bma\bac\bcs\bs)\b) | |

281 | _\bv_\bi is equivalent to _\bv_\bi_\b-_\bc_\bo_\bm_\bm_\ba_\bn_\bd; _\be_\bm_\ba_\bc_\bs is equivalent | |
282 | to _\be_\bm_\ba_\bc_\bs_\b-_\bs_\bt_\ba_\bn_\bd_\ba_\br_\bd. The default value is _\be_\bm_\ba_\bc_\bs; the | |

292 | If set to O\bOn\bn, readline will enable eight-bit input | |
293 | (that is, it will not strip the high bit from the | |
294 | characters it reads), regardless of what the termi- | |
295 | nal claims it can support. | |
296 | o\bou\but\btp\bpu\but\bt-\b-m\bme\bet\bta\ba (\b(O\bOf\bff\bf)\b) | |

305 | This alters the default behavior of the completion | |
306 | functions. If set to o\bon\bn, words which have more | |
307 | than one possible completion cause the matches to | |
308 | be listed immediately instead of ringing the bell. | |

315 | Readline implements a facility similar in spirit to the | |
316 | conditional compilation features of the C preprocessor | |
317 | which allows key bindings and variable settings to be per- | |
318 | formed as the result of tests. There are four parser | |
319 | directives used. | |
320 | ||
321 | $\b$i\bif\bf The $\b$i\bif\bf construct allows bindings to be made based | |
322 | on the editing mode, the terminal being used, or | |
323 | the application using readline. The text of the | |
324 | test extends to the end of the line; no characters | |

339 | m\bmo\bod\bde\be The m\bmo\bod\bde\be=\b= form of the $\b$i\bif\bf directive is used | |
340 | to test whether readline is in emacs or vi | |
341 | mode. This may be used in conjunction with | |
342 | the s\bse\bet\bt k\bke\bey\bym\bma\bap\bp command, for instance, to set | |
343 | bindings in the _\be_\bm_\ba_\bc_\bs_\b-_\bs_\bt_\ba_\bn_\bd_\ba_\br_\bd and _\be_\bm_\ba_\bc_\bs_\b- | |
344 | _\bc_\bt_\bl_\bx keymaps only if readline is starting | |
345 | out in emacs mode. | |
346 | ||
347 | t\bte\ber\brm\bm The t\bte\ber\brm\bm=\b= form may be used to include termi- | |
348 | nal-specific key bindings, perhaps to bind | |
349 | the key sequences output by the terminal's | |
350 | function keys. The word on the right side | |
351 | of the =\b= is tested against the full name of | |
352 | the terminal and the portion of the terminal | |
353 | name before the first -\b-. This allows _\bs_\bu_\bn to | |
354 | match both _\bs_\bu_\bn and _\bs_\bu_\bn_\b-_\bc_\bm_\bd, for instance. | |
355 | ||
356 | a\bap\bpp\bpl\bli\bic\bca\bat\bti\bio\bon\bn | |
357 | The a\bap\bpp\bpl\bli\bic\bca\bat\bti\bio\bon\bn construct is used to include | |
358 | application-specific settings. Each program | |
359 | using the readline library sets the _\ba_\bp_\bp_\bl_\bi_\bc_\ba_\b- | |
360 | _\bt_\bi_\bo_\bn _\bn_\ba_\bm_\be, and an initialization file can | |
361 | test for a particular value. This could be | |
362 | used to bind key sequences to functions use- | |
363 | ful for a specific program. For instance, | |
364 | the following command adds a key sequence | |
365 | that quotes the current or previous word in | |
366 | Bash: | |
367 | ||
368 | $\b$i\bif\bf bash | |
369 | # Quote the current or previous word | |
370 | "\C-xq": "\eb\"\ef\"" | |
371 | $\b$e\ben\bnd\bdi\bif\bf | |
372 | ||
373 | $\b$e\ben\bnd\bdi\bif\bf This command, as seen in the previous example, ter- | |
374 | minates an $\b$i\bif\bf command. | |
375 | ||
376 | $\b$e\bel\bls\bse\be Commands in this branch of the $\b$i\bif\bf directive are | |
377 | executed if the test fails. | |
378 | ||
379 | $\b$i\bin\bnc\bcl\blu\bud\bde\be | |
380 | This directive takes a single filename as an argu- | |
381 | ment and reads commands and bindings from that | |
382 | file. For example, the following directive would | |
383 | read _\b/_\be_\bt_\bc_\b/_\bi_\bn_\bp_\bu_\bt_\br_\bc: | |
384 | ||
385 | $\b$i\bin\bnc\bcl\blu\bud\bde\be _\b/_\be_\bt_\bc_\b/_\bi_\bn_\bp_\bu_\bt_\br_\bc | |

388 | Readline provides commands for searching through the com- | |
389 | mand history for lines containing a specified string. | |
390 | There are two search modes: _\bi_\bn_\bc_\br_\be_\bm_\be_\bn_\bt_\ba_\bl and _\bn_\bo_\bn_\b- | |

404 | ||
405 | Incremental searches begin before the user has finished | |
406 | typing the search string. As each character of the search | |
407 | string is typed, readline displays the next entry from the | |
408 | history matching the string typed so far. An incremental | |
409 | search requires only as many characters as needed to find | |
410 | the desired history entry. The Escape character is used | |
411 | to terminate an incremental search. Control-J will also | |
412 | terminate the search. Control-G will abort an incremental | |
413 | search and restore the original line. When the search is | |
414 | terminated, the history entry containing the search string | |
415 | becomes the current line. To find other matching entries | |
416 | in the history list, type Control-S or Control-R as appro- | |
417 | priate. This will search backward or forward in the his- | |
418 | tory for the next line matching the search string typed so | |
419 | far. Any other key sequence bound to a readline command | |
420 | will terminate the search and execute that command. For | |
421 | instance, a _\bn_\be_\bw_\bl_\bi_\bn_\be will terminate the search and accept | |
422 | the line, thereby executing the command from the history | |
423 | list. | |
424 | ||
425 | Non-incremental searches read the entire search string | |
426 | before starting to search for matching history lines. The | |
427 | search string may be typed by the user or be part of the | |
428 | contents of the current line. | |

667 | followed by a character that is neither a digit or | |
668 | minus sign, the argument count for the next command | |
669 | is multiplied by four. The argument count is ini- | |
670 | tially one, so executing this function the first | |
671 | time makes the argument count four, a second time | |
672 | makes the argument count sixteen, and so on. | |

676 | Attempt to perform completion on the text before | |

678 | tion-specific. B\bBa\bas\bsh\bh, for instance, attempts com- | |

680 | text begins with $\b$), username (if the text begins | |
681 | with ~\b~), hostname (if the text begins with @\b@), or | |
682 | command (including aliases and functions) in turn. | |
683 | If none of these produces a match, filename comple- | |
684 | tion is attempted. G\bGd\bdb\bb, on the other hand, allows | |
685 | completion of program functions and variables, and | |

700 | tions, inserting each match in turn. At the end of | |
701 | the list of completions, the bell is rung and the | |
702 | original text is restored. An argument of _\bn moves | |
703 | _\bn positions forward in the list of matches; a nega- | |
704 | tive argument may be used to move backward through | |
705 | the list. This command is intended to be bound to | |

823 | input line. In vi insertion mode, all characters not | |
824 | specifically mentioned are bound to _\bs_\be_\bl_\bf_\b-_\bi_\bn_\bs_\be_\br_\bt. Charac- | |
825 | ters assigned to signal generation by _\bs_\bt_\bt_\by(1) or the ter- | |
