Users of the 35 \fBtcsh shell\fR will find the default key bindings very familiar. Users of the 36 \fBbash\fR shell will also find it quite familiar, but with a few minor 37 differences, most notably in how forward and backward searches through the list 38 of historical commands are performed. There are two major editing modes, one 39 with \fBemacs\fR-like key bindings and another with \fBvi\fR-like key bindings. 40 By default \fBemacs\fR mode is enabled, but \fBvi\fR(1) mode can alternatively 41 be selected via the user's configuration file. This file can also be used to 42 change the bindings of individual keys to suit the user's preferences. By 43 default, tab completion is provided. If the application hasn't reconfigured 44 this to complete other types of symbols, then tab completion completes file 45 names. 46 .SS "Key Sequence Notation" 47 .sp 48 .LP 49 In the rest of this man page, and also in all tecla configuration files, key 50 sequences are expressed as follows. 51 .sp 52 .ne 2 53 .na 54 \fB\fB^A\fR or \fBC-a\fR\fR 55 .ad 56 .RS 13n 57 This is a 'CONTROL-A', entered by pressing the CONTROL key at the same time as 58 the 'A' key. 59 .RE 60 61 .sp 62 .ne 2 63 .na 64 \fB\fB\E\fR or \fBM-\fR\fR 65 .ad 66 .RS 13n 67 In key sequences, both of these notations can be entered either by pressing the 68 ESCAPE key, then the following key, or by pressing the META key at the same 69 time as the following key. Thus the key sequence \fBM-p\fR can be typed in two 70 ways, by pressing the ESCAPE key, followed by pressing 'P', or by pressing the 71 META key at the same time as 'P'. 72 .RE 73 74 .sp 75 .ne 2 76 .na 77 \fBup\fR 78 .ad 79 .RS 13n 80 This refers to the up-arrow key. 81 .RE 82 83 .sp 84 .ne 2 85 .na 86 \fBdown\fR 87 .ad 88 .RS 13n 89 This refers to the down-arrow key. 90 .RE 91 92 .sp 93 .ne 2 94 .na 95 \fBleft\fR 96 .ad 97 .RS 13n 98 This refers to the left-arrow key. 99 .RE 100 101 .sp 102 .ne 2 103 .na 104 \fBright\fR 105 .ad 106 .RS 13n 107 This refers to the right-arrow key. 108 .RE 109 110 .sp 111 .ne 2 112 .na 113 \fBa\fR 114 .ad 115 .RS 13n 116 This is just a normal 'A' key. 117 .RE 118 119 .SS "The Tecla Configuration File" 120 .sp 121 .LP 122 By default, tecla looks for a file called \fB\&.teclarc\fR in your home 123 directory (ie. \fB~/.teclarc\fR). If it finds this file, it reads it, 124 interpreting each line as defining a new key binding or an editing 125 configuration option. Since the \fBemacs\fR key-bindings are installed by 126 default, if you want to use the non-default \fBvi\fR editing mode, the most 127 important item to go in this file is the following line: 128 .sp 129 .in +2 130 .nf 131 edit-mode vi 132 .fi 133 .in -2 134 135 .sp 136 .LP 137 This will re-configure the default bindings for \fBvi\fR-mode. The complete set 138 of arguments that this command accepts are: 139 .sp 140 .ne 2 141 .na 142 \fBvi\fR 143 .ad 144 .RS 9n 145 Install key bindings like those of the \fBvi\fR editor. 146 .RE 147 148 .sp 149 .ne 2 150 .na 151 \fBemacs\fR 152 .ad 153 .RS 9n 154 Install key bindings like those of the \fBemacs\fR editor. This is the default. 155 .RE 156 157 .sp 158 .ne 2 159 .na 160 \fBnone\fR 161 .ad 162 .RS 9n 163 Use just the native line editing facilities provided by the terminal driver. 164 .RE 165 166 .sp 167 .LP 168 To prevent the terminal bell from being rung, such as when an unrecognized 169 control-sequence is typed, place the following line in the configuration file: 170 .sp 171 .in +2 172 .nf 173 nobeep 174 .fi 175 .in -2 176 177 .sp 178 .LP 179 An example of a key binding line in the configuration file is the following. 180 .sp 181 .in +2 182 .nf 183 bind M-[2~ insert-mode 184 .fi 185 .in -2 186 187 .sp 188 .LP 189 On many keyboards, the above key sequence is generated when one presses the 190 insert key, so with this key binding, one can toggle between the 191 \fBemacs\fR-mode insert and overwrite modes by hitting one key. One could also 192 do it by typing out the above sequence of characters one by one. As explained 193 above, the \fBM-\fR part of this sequence can be typed either by pressing the 194 ESCAPE key before the following key, or by pressing the META key at the same 195 time as the following key. Thus if you had set the above key binding, and the 196 insert key on your keyboard didn't generate the above key sequence, you could 197 still type it in either of the following 2 ways. 198 .RS +4 199 .TP 200 1. 201 Hit the ESCAPE key momentarily, then press '[', then '2', then finally '~'. 202 .RE 203 .RS +4 204 .TP 205 2. 206 Press the META key at the same time as pressing the '[' key, then press '2', 207 then '~'. 208 .RE 209 .sp 210 .LP 211 If you set a key binding for a key sequence that is already bound to a 212 function, the new binding overrides the old one. If in the new binding you omit 213 the name of the new function to bind to the key sequence, the original binding 214 becomes undefined. 215 .sp 216 .LP 217 Starting with versions of \fBlibtecla\fR later than 1.3.3 it is now possible to 218 bind key sequences that begin with a printable character. Previously key 219 sequences were required to start with a CONTROL or META character. 220 .sp 221 .LP 222 Note that the special keywords "up", "down", "left", and "right" refer to the 223 arrow keys, and are thus not treated as key sequences. So, for example, to 224 rebind the up and down arrow keys to use the history search mechanism instead 225 of the simple history recall method, you could place the following in your 226 configuration file: 227 .sp 228 .in +2 229 .nf 230 bind up history-search-backwards 231 bind down history-search-backwards 232 .fi 233 .in -2 234 235 .sp 236 .LP 237 To unbind an existing binding, you can do this with the bind command by 238 omitting to name any action to rebind the key sequence to. For example, by not 239 specifying an action function, the following command unbinds the default 240 beginning-of-line action from the \fB^A\fR key sequence: 241 .sp 242 .in +2 243 .nf 244 bind ^A 245 .fi 246 .in -2 247 248 .sp 249 .LP 250 If you create a \fB~/.teclarc\fR configuration file, but it appears to have no 251 effect on the program, check the documentation of the program to see if the 252 author chose a different name for this file. 253 .SS "Filename and Tilde Completion" 254 .sp 255 .LP 256 With the default key bindings, pressing the TAB key (aka. \fB^I\fR) results in 257 tecla attempting to complete the incomplete file name that precedes the cursor. 258 Tecla searches backwards from the cursor, looking for the start of the file 259 name, stopping when it hits either a space or the start of the line. If more 260 than one file has the specified prefix, then tecla completes the file name up 261 to the point at which the ambiguous matches start to differ, then lists the 262 possible matches. 263 .sp 264 .LP 265 In addition to literally written file names, tecla can complete files that 266 start with \fB~/\fR and \fB~user/\fR expressions and that contain \fB$envvar\fR 267 expressions. In particular, if you hit TAB within an incomplete \fB~user\fR, 268 expression, tecla will attempt to complete the username, listing any ambiguous 269 matches. 270 .sp 271 .LP 272 The completion binding is implemented using the \fBcpl_complete_word()\fR 273 function, which is also available separately to users of this library. See the 274 \fBcpl_complete_word\fR(3TECLA) man page for more details. 275 .SS "Filename Expansion" 276 .sp 277 .LP 278 With the default key bindings, pressing \fB^X*\fR causes tecla to expand the 279 file name that precedes the cursor, replacing \fB~/\fR and \fB~user/\fR 280 expressions with the corresponding home directories, and replacing 281 \fB$envvar\fR expressions with the value of the specified environment variable, 282 then if there are any wildcards, replacing the so far expanded file name with a 283 space-separated list of the files which match the wild cards. 284 .sp 285 .LP 286 The expansion binding is implemented using the \fBef_expand_file()\fR function. 287 See the \fBef_expand_file\fR(3TECLA) man page for more details. 288 .SS "Recalling Previously Typed Lines" 289 .sp 290 .LP 291 Every time that a new line is entered by the user, it is appended to a list of 292 historical input lines maintained within the \fBGetLine\fR resource object. You 293 can traverse up and down this list using the up and down arrow keys. 294 Alternatively, you can do the same with the \fB^P\fR, and \fB^N\fR keys, and in 295 \fBvi\fR command mode you can alternatively use the k and j characters. Thus 296 pressing up-arrow once, replaces the current input line with the previously 297 entered line. Pressing up-arrow again, replaces this with the line that was 298 entered before it, etc.. Having gone back one or more lines into the history 299 list, one can return to newer lines by pressing down-arrow one or more times. 300 If you do this sufficient times, you will return to the original line that you 301 were entering when you first hit up-arrow. 302 .sp 303 .LP 304 Note that in \fBvi\fR mode, all of the history recall functions switch the 305 library into command mode. 306 .sp 307 .LP 308 In \fBemacs\fR mode the \fBM-p\fR and \fBM-n\fR keys work just like the 309 \fB^P\fR and \fB^N\fR keys, except that they skip all but those historical 310 lines which share the prefix that precedes the cursor. In \fBvi\fR command mode 311 the upper case 'K' and 'J' characters do the same thing, except that the string 312 that they search for includes the character under the cursor as well as what 313 precedes it. 314 .sp 315 .LP 316 Thus for example, suppose that you were in \fBemacs\fR mode, and you had just 317 entered the following list of commands in the order shown: 318 .sp 319 .in +2 320 .nf 321 ls ~/tecla/ 322 cd ~/tecla 323 ls -l getline.c 324 \fBemacs\fR ~/tecla/getline.c 325 .fi 326 .in -2 327 328 .sp 329 .LP 330 If you next typed: 331 .sp 332 .in +2 333 .nf 334 ls 335 .fi 336 .in -2 337 338 .sp 339 .LP 340 and then hit \fBM-p\fR, then rather than returning the previously typed 341 \fBemacs\fR line, which doesn't start with "ls", tecla would recall the "ls -l 342 getline.c" line. Pressing \fBM-p\fR again would recall the "ls ~/tecla/" line. 343 .sp 344 .LP 345 Note that if the string that you are searching for, contains any of the special 346 characters, *, ?, or '[', then it is interpretted as a pattern to be matched. 347 Thus, cotinuing with the above example, after typing in the list of commands 348 shown, if you then typed: 349 .sp 350 .in +2 351 .nf 352 *tecla* 353 .fi 354 .in -2 355 356 .sp 357 .LP 358 and hit \fBM-p\fR, then the "\fBemacs\fR ~/tecla/getline.c" line would be 359 recalled first, since it contains the word tecla somewhere in the line, 360 Similarly, hitting \fBM-p\fR again, would recall the "ls ~/tecla/" line, and 361 hitting it once more would recall the "ls ~/tecla/" line. The pattern syntax is 362 the same as that described for file name expansion, in the 363 \fBef_expand_file\fR(3TECLA). 364 .SS "History Files" 365 .sp 366 .LP 367 Authors of programs that use the tecla library have the option of saving 368 historical command-lines in a file before exiting, and subsequently reading 369 them back in from this file when the program is next started. There is no 370 standard name for this file, since it makes sense for each application to use 371 its own history file, so that commands from different applications don't get 372 mixed up. 373 .SS "International Character Sets" 374 .sp 375 .LP 376 Since \fBlibtecla\fR version 1.4.0, tecla has been 8-bit clean. This means that 377 all 8-bit characters that are printable in the user's current locale are now 378 displayed verbatim and included in the returned input line. Assuming that the 379 calling program correctly contains a call like the following, 380 .sp 381 .in +2 382 .nf 383 setlocale(LC_CTYPE, ""); 384 .fi 385 .in -2 386 387 .sp 388 .LP 389 then the current locale is determined by the first of the environment variables 390 \fBLC_CTYPE\fR, \fBLC_ALL\fR, and \fBLANG\fR, that is found to contain a valid 391 locale name. If none of these variables are defined, or the program neglects to 392 call \fBsetlocale\fR, then the default C locale is used, which is US 7-bit 393 ASCII. On most unix-like platforms, you can get a list of valid locales by 394 typing the command: 395 .sp 396 .in +2 397 .nf 398 locale -a 399 .fi 400 .in -2 401 402 .sp 403 .LP 404 at the shell prompt. 405 .SS "Meta Keys and Locales" 406 .sp 407 .LP 408 Beware that in most locales other than the default C locale, META characters 409 become printable, and they are then no longer considered to match \fBM-c\fR 410 style key bindings. This allows international characters to be entered with the 411 compose key without unexpectedly triggering META key bindings. You can still 412 invoke META bindings, since there are actually two ways to do this. For example 413 the binding \fBM-c\fR can also be invoked by pressing the ESCAPE key 414 momentarily, then pressing the c key, and this will work regardless of locale. 415 Moreover, many modern terminal emulators, such as gnome's gnome-terminal's and 416 KDE's konsole terminals, already generate escape pairs like this when you use 417 the META key, rather than a real meta character, and other emulators usually 418 have a way to request this behavior, so you can continue to use the META key on 419 most systems. 420 .sp 421 .LP 422 For example, although xterm terminal emulators generate real 8-bit meta 423 characters by default when you use the META key, they can be configured to 424 output the equivalent escape pair by setting their \fBEightBitInput\fR X 425 resource to False. You can either do this by placing a line like the following 426 in your \fB~/.Xdefaults\fR file, 427 .sp 428 .in +2 429 .nf 430 XTerm*EightBitInput: False 431 .fi 432 .in -2 433 434 .sp 435 .LP 436 or by starting an \fBxterm\fR with an \fB-xrm\fR \&'*EightBitInput: False' 437 command-line argument. In recent versions of xterm you can toggle this feature 438 on and off with the 'Meta Sends Escape' option in the menu that is displayed 439 when you press the left mouse button and the CONTROL key within an xterm 440 window. In CDE, dtterms can be similarly coerced to generate escape pairs in 441 place of meta characters, by setting the \fBDtterm*KshMode\fR resource to True. 442 .SS "Entering International Characters" 443 .sp 444 .LP 445 If you don't have a keyboard that generates all of the international characters 446 that you need, there is usually a compose key that will allow you to enter 447 special characters, or a way to create one. For example, under X windows on 448 unix-like systems, if your keyboard doesn't have a compose key, you can 449 designate a redundant key to serve this purpose with the xmodmap command. For 450 example, on many PC keyboards there is a microsoft-windows key, which is 451 otherwise useless under Linux. On a laptop, for example, the \fBxev\fR program 452 might report that pressing this key generates keycode 115. To turn this key 453 into a COMPOSE key, do the following: 454 .sp 455 .in +2 456 .nf 457 xmodmap -e 'keycode 115 = Multi_key' 458 .fi 459 .in -2 460 461 .sp 462 .LP 463 Type this key followed by a " character to enter an 'I' with a umlaut over it. 464 .SS "The Available Key Binding Functions" 465 .sp 466 .LP 467 The following is a list of the editing functions provided by the tecla library. 468 The names in the leftmost column of the list can be used in configuration files 469 to specify which function a given key or combination of keys should invoke. 470 They are also used in the next two sections to list the default key bindings in 471 \fBemacs\fR and \fBvi\fR modes. 472 .sp 473 .ne 2 474 .na 475 \fBuser-interrupt\fR 476 .ad 477 .RS 30n 478 Send a SIGINT signal to the parent process. 479 .RE 480 481 .sp 482 .ne 2 483 .na 484 \fBsuspend\fR 485 .ad 486 .RS 30n 487 Suspend the parent process. 488 .RE 489 490 .sp 491 .ne 2 492 .na 493 \fBstop-output\fR 494 .ad 495 .RS 30n 496 Pause terminal output. 497 .RE 498 499 .sp 500 .ne 2 501 .na 502 \fBstart-output\fR 503 .ad 504 .RS 30n 505 Resume paused terminal output. 506 .RE 507 508 .sp 509 .ne 2 510 .na 511 \fBliteral-next\fR 512 .ad 513 .RS 30n 514 Arrange for the next character to be treated as a normal character.

This is interpreted as a repeat count 3570 by most bindings. A notable exception is the goto-column binding, which 3571 interprets the count as a column number. 3572 .sp 3573 .LP 3574 By default you can specify this count argument by pressing the META key while 3575 typing in the numeric count. This relies on the digit-argument action being 3576 bound to 'META-0', 'META-1' etc. Once any one of these bindings has been 3577 activated, you can optionally take your finger off the META key to type in the 3578 rest of the number, since every numeric digit thereafter is treated as part of 3579 the number, unless it is preceded by the literal-next binding. As soon as a 3580 non-digit, or literal digit key is pressed the repeat count is terminated and 3581 either causes the just typed character to be added to the line that many times, 3582 or causes the next key binding function to be given that argument. 3583 .sp 3584 .LP 3585 For example, in \fBemacs\fR mode, typing: 3586 .sp 3587 .in +2 3588 .nf 3589 M-12a 3590 .fi 3591 .in -2 3592 3593 .sp 3594 .LP 3595 causes the letter 'a' to be added to the line 12 times, whereas 3596 .sp 3597 .in +2 3598 .nf 3599 M-4M-c 3600 .fi 3601 .in -2 3602 3603 .sp 3604 .LP 3605 Capitalizes the next 4 words. 3606 .sp 3607 .LP 3608 In \fBvi\fR command mode the meta modifier is automatically added to all 3609 characters typed in, so to enter a count in \fBvi\fR command-mode, just 3610 involves typing in the number, just as it does in the \fBvi\fR editor itself. 3611 So for example, in vi command mode, typing: 3612 .sp 3613 .in +2 3614 .nf 3615 4w2x 3616 .fi 3617 .in -2 3618 3619 .sp 3620 .LP 3621 moves the cursor four words to the right, then deletes two characters. 3622 .sp 3623 .LP 3624 You can also bind digit-argument to other key sequences. If these end in a 3625 numeric digit, that digit gets appended to the current repeat count. If it 3626 doesn't end in a numeric digit, a new repeat count is started with a value of 3627 zero, and can be completed by typing in the number, after letting go of the key 3628 which triggered the digit-argument action. 3629 .SH FILES 3630 .sp 3631 .ne 2 3632 .na 3633 \fB\fB/usr/lib/libtecla.so\fR\fR 3634 .ad 3635 .RS 27n 3636 The tecla library 3637 .RE 3638 3639 .sp 3640 .ne 2 3641 .na 3642 \fB\fB/usr/include/libtecla.h\fR\fR 3643 .ad 3644 .RS 27n 3645 The tecla header file 3646 .RE 3647 3648 .sp 3649 .ne 2 3650 .na 3651 \fB\fB~/.teclarc\fR\fR 3652 .ad 3653 .RS 27n 3654 The personal tecla customization file 3655 .RE 3656 3657 .SH ATTRIBUTES 3658 .sp 3659 .LP 3660 See \fBattributes\fR(5) for descriptions of the following attributes: 3661 .sp 3662 3663 .sp 3664 .TS 3665 box; 3666 c | c 3667 l | l . 3668 ATTRIBUTE TYPE ATTRIBUTE VALUE 3669 _ 3670 Interface Stability Evolving 3671 .TE 3672 3673 .SH SEE ALSO 3674 .sp 3675 .LP 3676 \fBvi\fR(1), \fBcpl_complete_word\fR(3TECLA), \fBef_expand_file\fR(3TECLA), 3677 \fBgl_get_line\fR(3TECLA), \fBgl_io_mode\fR(3TECLA), \fBlibtecla\fR(3LIB), 3678 \fBpca_lookup_file\fR(3TECLA), \fBattributes\fR(5)
