5 5 NAME
6 6 tecla, teclarc - User interface provided by the tecla library.
7 7
8 8 DESCRIPTION
9 9 This man page describes the command-line editing features that are
10 10 available to users of programs that read keyboard input via the tecla
11 11 library. Users of the tcsh shell will find the default key bindings
12 12 very familiar. Users of the bash shell will also find it quite
13 13 familiar, but with a few minor differences, most notably in how forward
14 14 and backward searches through the list of historical commands are
15 15 performed. There are two major editing modes, one with emacs-like key
16 16 bindings and another with vi-like key bindings. By default emacs mode
17 17 is enabled, but vi(1) mode can alternatively be selected via the user's
18 18 configuration file. This file can also be used to change the bindings
19 19 of individual keys to suit the user's preferences. By default, tab
20 20 completion is provided. If the application hasn't reconfigured this to
21 21 complete other types of symbols, then tab completion completes file
22 22 names.
23 23
24 24 Key Sequence Notation
25 25 In the rest of this man page, and also in all tecla configuration
26 26 files, key sequences are expressed as follows.
27 27
28 28 ^A or C-a
29 29 This is a 'CONTROL-A', entered by pressing the CONTROL key
30 30 at the same time as the 'A' key.
31 31
32 32
33 33 \E or M-
34 34 In key sequences, both of these notations can be entered
35 35 either by pressing the ESCAPE key, then the following key,
36 36 or by pressing the META key at the same time as the
37 37 following key. Thus the key sequence M-p can be typed in
38 38 two ways, by pressing the ESCAPE key, followed by pressing
39 39 'P', or by pressing the META key at the same time as 'P'.
40 40
41 41
42 42 up
43 43 This refers to the up-arrow key.
44 44
45 45
46 46 down
47 47 This refers to the down-arrow key.
48 48
49 49
50 50 left
51 51 This refers to the left-arrow key.
52 52
53 53
54 54 right
55 55 This refers to the right-arrow key.
56 56
57 57
58 58 a
59 59 This is just a normal 'A' key.
60 60
61 61
62 62 The Tecla Configuration File
63 63 By default, tecla looks for a file called .teclarc in your home
64 64 directory (ie. ~/.teclarc). If it finds this file, it reads it,
65 65 interpreting each line as defining a new key binding or an editing
66 66 configuration option. Since the emacs key-bindings are installed by
67 67 default, if you want to use the non-default vi editing mode, the most
68 68 important item to go in this file is the following line:
69 69
70 70 edit-mode vi
71 71
72 72
73 73
74 74 This will re-configure the default bindings for vi-mode. The complete
75 75 set of arguments that this command accepts are:
76 76
77 77 vi
78 78 Install key bindings like those of the vi editor.
79 79
80 80
81 81 emacs
82 82 Install key bindings like those of the emacs editor. This is
83 83 the default.
84 84
85 85
86 86 none
87 87 Use just the native line editing facilities provided by the
88 88 terminal driver.
89 89
90 90
91 91
92 92 To prevent the terminal bell from being rung, such as when an
93 93 unrecognized control-sequence is typed, place the following line in the
94 94 configuration file:
95 95
96 96 nobeep
97 97
98 98
99 99
100 100 An example of a key binding line in the configuration file is the
101 101 following.
102 102
103 103 bind M-[2~ insert-mode
104 104
105 105
106 106
107 107 On many keyboards, the above key sequence is generated when one presses
108 108 the insert key, so with this key binding, one can toggle between the
109 109 emacs-mode insert and overwrite modes by hitting one key. One could
110 110 also do it by typing out the above sequence of characters one by one.
111 111 As explained above, the M- part of this sequence can be typed either by
112 112 pressing the ESCAPE key before the following key, or by pressing the
113 113 META key at the same time as the following key. Thus if you had set the
114 114 above key binding, and the insert key on your keyboard didn't generate
115 115 the above key sequence, you could still type it in either of the
116 116 following 2 ways.
117 117
118 118 1. Hit the ESCAPE key momentarily, then press '[', then '2',
119 119 then finally '~'.
120 120
121 121 2. Press the META key at the same time as pressing the '[' key,
122 122 then press '2', then '~'.
123 123
124 124
125 125 If you set a key binding for a key sequence that is already bound to a
126 126 function, the new binding overrides the old one. If in the new binding
127 127 you omit the name of the new function to bind to the key sequence, the
128 128 original binding becomes undefined.
129 129
130 130
131 131 Starting with versions of libtecla later than 1.3.3 it is now possible
132 132 to bind key sequences that begin with a printable character. Previously
133 133 key sequences were required to start with a CONTROL or META character.
134 134
135 135
136 136 Note that the special keywords "up", "down", "left", and "right" refer
137 137 to the arrow keys, and are thus not treated as key sequences. So, for
138 138 example, to rebind the up and down arrow keys to use the history search
139 139 mechanism instead of the simple history recall method, you could place
140 140 the following in your configuration file:
141 141
142 142 bind up history-search-backwards
143 143 bind down history-search-backwards
144 144
145 145
146 146
147 147 To unbind an existing binding, you can do this with the bind command by
148 148 omitting to name any action to rebind the key sequence to. For example,
149 149 by not specifying an action function, the following command unbinds the
150 150 default beginning-of-line action from the ^A key sequence:
151 151
152 152 bind ^A
153 153
154 154
155 155
156 156 If you create a ~/.teclarc configuration file, but it appears to have
157 157 no effect on the program, check the documentation of the program to see
158 158 if the author chose a different name for this file.
159 159
160 160 Filename and Tilde Completion
161 161 With the default key bindings, pressing the TAB key (aka. ^I) results
162 162 in tecla attempting to complete the incomplete file name that precedes
163 163 the cursor. Tecla searches backwards from the cursor, looking for the
164 164 start of the file name, stopping when it hits either a space or the
165 165 start of the line. If more than one file has the specified prefix, then
166 166 tecla completes the file name up to the point at which the ambiguous
167 167 matches start to differ, then lists the possible matches.
168 168
169 169
170 170 In addition to literally written file names, tecla can complete files
171 171 that start with ~/ and ~user/ expressions and that contain $envvar
172 172 expressions. In particular, if you hit TAB within an incomplete ~user,
173 173 expression, tecla will attempt to complete the username, listing any
174 174 ambiguous matches.
175 175
176 176
177 177 The completion binding is implemented using the cpl_complete_word()
178 178 function, which is also available separately to users of this library.
179 179 See the cpl_complete_word(3TECLA) man page for more details.
180 180
181 181 Filename Expansion
182 182 With the default key bindings, pressing ^X* causes tecla to expand the
183 183 file name that precedes the cursor, replacing ~/ and ~user/ expressions
184 184 with the corresponding home directories, and replacing $envvar
185 185 expressions with the value of the specified environment variable, then
186 186 if there are any wildcards, replacing the so far expanded file name
187 187 with a space-separated list of the files which match the wild cards.
188 188
189 189
190 190 The expansion binding is implemented using the ef_expand_file()
191 191 function. See the ef_expand_file(3TECLA) man page for more details.
192 192
193 193 Recalling Previously Typed Lines
194 194 Every time that a new line is entered by the user, it is appended to a
195 195 list of historical input lines maintained within the GetLine resource
196 196 object. You can traverse up and down this list using the up and down
197 197 arrow keys. Alternatively, you can do the same with the ^P, and ^N
198 198 keys, and in vi command mode you can alternatively use the k and j
199 199 characters. Thus pressing up-arrow once, replaces the current input
200 200 line with the previously entered line. Pressing up-arrow again,
201 201 replaces this with the line that was entered before it, etc.. Having
202 202 gone back one or more lines into the history list, one can return to
203 203 newer lines by pressing down-arrow one or more times. If you do this
204 204 sufficient times, you will return to the original line that you were
205 205 entering when you first hit up-arrow.
206 206
207 207
208 208 Note that in vi mode, all of the history recall functions switch the
209 209 library into command mode.
210 210
211 211
212 212 In emacs mode the M-p and M-n keys work just like the ^P and ^N keys,
213 213 except that they skip all but those historical lines which share the
214 214 prefix that precedes the cursor. In vi command mode the upper case 'K'
215 215 and 'J' characters do the same thing, except that the string that they
216 216 search for includes the character under the cursor as well as what
217 217 precedes it.
218 218
219 219
220 220 Thus for example, suppose that you were in emacs mode, and you had just
221 221 entered the following list of commands in the order shown:
222 222
223 223 ls ~/tecla/
224 224 cd ~/tecla
225 225 ls -l getline.c
226 226 emacs ~/tecla/getline.c
227 227
228 228
229 229
230 230 If you next typed:
231 231
232 232 ls
233 233
234 234
235 235
236 236 and then hit M-p, then rather than returning the previously typed emacs
237 237 line, which doesn't start with "ls", tecla would recall the "ls -l
238 238 getline.c" line. Pressing M-p again would recall the "ls ~/tecla/"
239 239 line.
240 240
241 241
242 242 Note that if the string that you are searching for, contains any of the
243 243 special characters, *, ?, or '[', then it is interpreted as a pattern
244 244 to be matched. Thus, continuing with the above example, after typing
245 245 in the list of commands shown, if you then typed:
246 246
247 247 *tecla*
248 248
249 249
250 250
251 251 and hit M-p, then the "emacs ~/tecla/getline.c" line would be recalled
252 252 first, since it contains the word tecla somewhere in the line,
253 253 Similarly, hitting M-p again, would recall the "ls ~/tecla/" line, and
254 254 hitting it once more would recall the "ls ~/tecla/" line. The pattern
255 255 syntax is the same as that described for file name expansion, in the
256 256 ef_expand_file(3TECLA).
257 257
258 258 History Files
259 259 Authors of programs that use the tecla library have the option of
260 260 saving historical command-lines in a file before exiting, and
261 261 subsequently reading them back in from this file when the program is
262 262 next started. There is no standard name for this file, since it makes
263 263 sense for each application to use its own history file, so that
264 264 commands from different applications don't get mixed up.
265 265
266 266 International Character Sets
267 267 Since libtecla version 1.4.0, tecla has been 8-bit clean. This means
268 268 that all 8-bit characters that are printable in the user's current
269 269 locale are now displayed verbatim and included in the returned input
270 270 line. Assuming that the calling program correctly contains a call like
271 271 the following,
272 272
273 273 setlocale(LC_CTYPE, "");
274 274
275 275
276 276
277 277 then the current locale is determined by the first of the environment
278 278 variables LC_CTYPE, LC_ALL, and LANG, that is found to contain a valid
279 279 locale name. If none of these variables are defined, or the program
280 280 neglects to call setlocale, then the default C locale is used, which is
281 281 US 7-bit ASCII. On most unix-like platforms, you can get a list of
282 282 valid locales by typing the command:
283 283
284 284 locale -a
285 285
286 286
287 287
288 288 at the shell prompt.
289 289
290 290 Meta Keys and Locales
291 291 Beware that in most locales other than the default C locale, META
292 292 characters become printable, and they are then no longer considered to
293 293 match M-c style key bindings. This allows international characters to
294 294 be entered with the compose key without unexpectedly triggering META
295 295 key bindings. You can still invoke META bindings, since there are
296 296 actually two ways to do this. For example the binding M-c can also be
297 297 invoked by pressing the ESCAPE key momentarily, then pressing the c
298 298 key, and this will work regardless of locale. Moreover, many modern
299 299 terminal emulators, such as gnome's gnome-terminal's and KDE's konsole
300 300 terminals, already generate escape pairs like this when you use the
301 301 META key, rather than a real meta character, and other emulators
302 302 usually have a way to request this behavior, so you can continue to use
303 303 the META key on most systems.
304 304
305 305
306 306 For example, although xterm terminal emulators generate real 8-bit meta
307 307 characters by default when you use the META key, they can be configured
308 308 to output the equivalent escape pair by setting their EightBitInput X
309 309 resource to False. You can either do this by placing a line like the
310 310 following in your ~/.Xdefaults file,
311 311
312 312 XTerm*EightBitInput: False
313 313
314 314
315 315
316 316 or by starting an xterm with an -xrm '*EightBitInput: False' command-
317 317 line argument. In recent versions of xterm you can toggle this feature
318 318 on and off with the 'Meta Sends Escape' option in the menu that is
319 319 displayed when you press the left mouse button and the CONTROL key
320 320 within an xterm window. In CDE, dtterms can be similarly coerced to
321 321 generate escape pairs in place of meta characters, by setting the
322 322 Dtterm*KshMode resource to True.
323 323
324 324 Entering International Characters
325 325 If you don't have a keyboard that generates all of the international
326 326 characters that you need, there is usually a compose key that will
327 327 allow you to enter special characters, or a way to create one. For
328 328 example, under X windows on unix-like systems, if your keyboard doesn't
329 329 have a compose key, you can designate a redundant key to serve this
330 330 purpose with the xmodmap command. For example, on many PC keyboards
331 331 there is a microsoft-windows key, which is otherwise useless under
332 332 Linux. On a laptop, for example, the xev program might report that
333 333 pressing this key generates keycode 115. To turn this key into a
334 334 COMPOSE key, do the following:
335 335
336 336 xmodmap -e 'keycode 115 = Multi_key'
337 337
338 338
339 339
340 340 Type this key followed by a " character to enter an 'I' with a umlaut
341 341 over it.
342 342
343 343 The Available Key Binding Functions
344 344 The following is a list of the editing functions provided by the tecla
345 345 library. The names in the leftmost column of the list can be used in
346 346 configuration files to specify which function a given key or
347 347 combination of keys should invoke. They are also used in the next two
348 348 sections to list the default key bindings in emacs and vi modes.
349 349
350 350 user-interrupt
351 351 Send a SIGINT signal to the parent
352 352 process.
353 353
354 354

382 382 Toggle between insert mode and overwrite
383 383 mode.
384 384
385 385
386 386 beginning-of-line
387 387 Move the cursor to the beginning of the
388 388 line.
389 389
390 390
391 391 end-of-line
392 392 Move the cursor to the end of the line.
393 393
394 394
395 395 delete-line
396 396 Delete the contents of the current line.
397 397
398 398
399 399 kill-line
400 400 Delete everything that follows the
401 401 cursor.
402 402
403 403
404 404 backward-kill-line
405 405 Delete all characters between the cursor
406 406 and the start of the line.
407 407
408 408
409 409 forward-word
410 410 Move to the end of the word which follows
411 411 the cursor.
412 412
413 413
414 414 forward-to-word
415 415 Move the cursor to the start of the word
416 416 that follows the cursor.
417 417
418 418
419 419 backward-word
420 420 Move to the start of the word which
421 421 precedes the cursor.
422 422
423 423
424 424 goto-column
425 425 Move the cursor to the 1-relative column
426 426 in the line specified by any preceding
427 427 digit-argument sequences (see Entering
428 428 Repeat Counts below).
429 429
430 430
431 431 find-parenthesis
432 432 If the cursor is currently over a
433 433 parenthesis character, move it to the
434 434 matching parenthesis character. If not
435 435 over a parenthesis character move right
436 436 to the next close parenthesis.
437 437
438 438
439 439 forward-delete-char
440 440 Delete the character under the cursor.
441 441
442 442
443 443 backward-delete-char
444 444 Delete the character which precedes the
445 445 cursor.
446 446
447 447
448 448 list-or-eof
449 449 This is intended for binding to ^D. When
450 450 invoked when the cursor is within the
451 451 line it displays all possible completions
452 452 then redisplays the line unchanged. When
453 453 invoked on an empty line, it signals end-
454 454 of-input (EOF) to the caller of
455 455 gl_get_line().
456 456
457 457
458 458 del-char-or-list-or-eof
459 459 This is intended for binding to ^D. When
460 460 invoked when the cursor is within the
461 461 line it invokes forward-delete-char. When
462 462 invoked at the end of the line it
463 463 displays all possible completions then
464 464 redisplays the line unchanged. When
465 465 invoked on an empty line, it signals end-
466 466 of-input (EOF) to the caller of
467 467 gl_get_line().
468 468
469 469
470 470 forward-delete-word
471 471 Delete the word which follows the cursor.
472 472
473 473
474 474 backward-delete-word
475 475 Delete the word which precedes the
476 476 cursor.
477 477
478 478
479 479 upcase-word
480 480 Convert all of the characters of the word
481 481 which follows the cursor, to upper case.
482 482
483 483
484 484 downcase-word
485 485 Convert all of the characters of the word
486 486 which follows the cursor, to lower case.
487 487
488 488
489 489 capitalize-word
490 490 Capitalize the word which follows the
491 491 cursor.
492 492

661 661 of the line, after appending a newline
662 662 character. The newline character is
663 663 normally '\n', but will be the first
664 664 character of the key sequence that
665 665 invoked the newline action, if this
666 666 happens to be a printable character. If
667 667 the action was invoked by the '\n'
668 668 newline character or the '\r' carriage
669 669 return character, the line is appended to
670 670 the history buffer.

1231 1231 Note that ^I is what the TAB key generates, and that ^@ can be
1232 1232 generated not only by pressing the CONTROL key and the @ key
1233 1233 simultaneously, but also by pressing the CONTROL key and the space bar
1234 1234 at the same time.
1235 1235
1236 1236 Default Key Bindings in vi Mode
1237 1237 The following default key bindings are designed to mimic the vi style
1238 1238 of editing as closely as possible. This means that very few editing
1239 1239 functions are provided in the initial character input mode, editing
1240 1240 functions instead being provided by the vi command mode. The vi command
1241 1241 mode is entered whenever the ESCAPE character is pressed, or whenever a
1242 1242 key sequence that starts with a meta character is entered. In addition
1243 1243 to mimicing vi, libtecla provides bindings for tab completion, wild-
1244 1244 card expansion of file names, and historical line recall.
1245 1245
1246 1246
1247 1247 To learn how to tell the tecla library to use vi mode instead of the
1248 1248 default emacs editing mode, see the earlier section entitled The Tecla
1249 1249 Configuration File.
1250 1250
1251 1251
1252 1252 Under UNIX the terminal driver sets a number of special keys for
1253 1253 certain functions. The tecla library attempts to use the same key
1254 1254 bindings to maintain consistency, binding them both in input mode and
1255 1255 in command mode. The key sequences shown for the following 6 bindings
1256 1256 are thus just examples of what they will probably be set to. If you
1257 1257 have used the stty command to change these keys, then the default
1258 1258 bindings should match.

1305 1305 Note that above, most of the bindings are defined twice, once as a raw
1306 1306 control code like ^C and then a second time as a META character like
1307 1307 M-^C. The former is the binding for vi input mode, whereas the latter
1308 1308 is the binding for vi command mode. Once in command mode all key
1309 1309 sequences that the user types that they don't explicitly start with an
1310 1310 ESCAPE or a META key, have their first key secretly converted to a META
1311 1311 character before the key sequence is looked up in the key binding
1312 1312 table. Thus, once in command mode, when you type the letter i, for
1313 1313 example, the tecla library actually looks up the binding for M-i.
1314 1314
1315 1315
1316 1316 The cursor keys are referred to by name, as follows. This is necessary
1317 1317 because different types of terminals generate different key sequences
1318 1318 when their cursor keys are pressed.

1337 1337 The cursor keys normally generate a key sequence that start with an

1339 1339 command mode (if you aren't already in command mode).

1410 1410 The following are the key bindings that are defined in vi command mode,
1411 1411 this being specified by them all starting with a META character. As
1412 1412 mentioned above, once in command mode the initial meta character is
1413 1413 optional. For example, you might enter command mode by typing ESCAPE,
1414 1414 and then press 'H' twice to move the cursor two positions to the left.
1415 1415 Both 'H' characters get quietly converted to M-h before being compared
1416 1416 to the key binding table, the first one because ESCAPE followed by a
1417 1417 character is always converted to the equivalent META character, and the
1418 1418 second because command mode was already active.

1957 1957 Note that ^I is what the TAB key generates.
1958 1958
1959 1959 Entering Repeat Counts
1960 1960 Many of the key binding functions described previously, take an
1961 1961 optional count, typed in before the target key sequence. This is
1962 1962 interpreted as a repeat count by most bindings. A notable exception is
1963 1963 the goto-column binding, which interprets the count as a column number.
1964 1964
1965 1965
1966 1966 By default you can specify this count argument by pressing the META key
1967 1967 while typing in the numeric count. This relies on the digit-argument
1968 1968 action being bound to 'META-0', 'META-1' etc. Once any one of these
1969 1969 bindings has been activated, you can optionally take your finger off
1970 1970 the META key to type in the rest of the number, since every numeric
1971 1971 digit thereafter is treated as part of the number, unless it is
1972 1972 preceded by the literal-next binding. As soon as a non-digit, or
1973 1973 literal digit key is pressed the repeat count is terminated and either
1974 1974 causes the just typed character to be added to the line that many
1975 1975 times, or causes the next key binding function to be given that
1976 1976 argument.
1977 1977
1978 1978
1979 1979 For example, in emacs mode, typing:
1980 1980
1981 1981 M-12a
1982 1982
1983 1983
1984 1984
1985 1985 causes the letter 'a' to be added to the line 12 times, whereas
1986 1986
1987 1987 M-4M-c
1988 1988
1989 1989
1990 1990
1991 1991 Capitalizes the next 4 words.
1992 1992
1993 1993
1994 1994 In vi command mode the meta modifier is automatically added to all
1995 1995 characters typed in, so to enter a count in vi command-mode, just
1996 1996 involves typing in the number, just as it does in the vi editor itself.
1997 1997 So for example, in vi command mode, typing:
1998 1998
1999 1999 4w2x
2000 2000
2001 2001
2002 2002
2003 2003 moves the cursor four words to the right, then deletes two characters.
2004 2004
2005 2005
2006 2006 You can also bind digit-argument to other key sequences. If these end
2007 2007 in a numeric digit, that digit gets appended to the current repeat
2008 2008 count. If it doesn't end in a numeric digit, a new repeat count is
2009 2009 started with a value of zero, and can be completed by typing in the
2010 2010 number, after letting go of the key which triggered the digit-argument
2011 2011 action.
