  27 .TH TECLA 5 "April 9, 2016"
  28 .SH NAME
  29 tecla, teclarc \- User interface provided by the tecla library.
  30 .SH DESCRIPTION
  31 .LP
  32 This man page describes the command-line editing features that are available to
  33 users of programs that read keyboard input via the tecla library. Users of the
  34 \fBtcsh shell\fR will find the default key bindings very familiar. Users of the
  35 \fBbash\fR shell will also find it quite familiar, but with a few minor
  36 differences, most notably in how forward and backward searches through the list
  37 of historical commands are performed. There are two major editing modes, one
  38 with \fBemacs\fR-like key bindings and another with \fBvi\fR-like key bindings.
  39 By default \fBemacs\fR mode is enabled, but \fBvi\fR(1) mode can alternatively
  40 be selected via the user's configuration file. This file can also be used to
  41 change the bindings of individual keys to suit the user's preferences. By
  42 default, tab completion is provided. If the application hasn't reconfigured
  43 this to complete other types of symbols, then tab completion completes file
  44 names.
  45 .SS "Key Sequence Notation"
  46 .LP
  47 In the rest of this man page, and also in all tecla configuration files, key
  48 sequences are expressed as follows.
  49 .sp
  50 .ne 2
  51 .na
  52 \fB\fB^A\fR or \fBC-a\fR\fR
  53 .ad
  54 .RS 13n
  55 This is a 'CONTROL-A', entered by pressing the CONTROL key at the same time as
  56 the 'A' key.
  57 .RE
  58 
  59 .sp
  60 .ne 2
  61 .na
  62 \fB\eE\fR or \fBM-\fR
  63 .ad
  64 .RS 13n
  65 In key sequences, both of these notations can be entered either by pressing the
  66 ESCAPE key, then the following key, or by pressing the META key at the same
  67 time as the following key. Thus the key sequence \fBM-p\fR can be typed in two
  68 ways, by pressing the ESCAPE key, followed by pressing 'P', or by pressing the
  69 META key at the same time as 'P'.

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

1510 Under UNIX the terminal driver sets a number of special keys for certain

2010 provided by the \fBvi\fR command mode. The \fBvi\fR command mode is entered
2011 whenever the ESCAPE character is pressed, or whenever a key sequence that
2012 starts with a meta character is entered. In addition to mimicing \fBvi\fR,
2013 \fBlibtecla\fR provides bindings for tab completion, wild-card expansion of
2014 file names, and historical line recall.

2017 To learn how to tell the tecla library to use \fBvi\fR mode instead of the
2018 default \fBemacs\fR editing mode, see the earlier section entitled The Tecla
2019 Configuration File.

2022 Under UNIX the terminal driver sets a number of special keys for certain
2023 functions. The tecla library attempts to use the same key bindings to maintain
2024 consistency, binding them both in input mode and in command mode. The key
2025 sequences shown for the following 6 bindings are thus just examples of what
2026 they will probably be set to. If you have used the \fBstty\fR command to change
2027 these keys, then the default bindings should match.

2129 Note that above, most of the bindings are defined twice, once as a raw control
2130 code like \fB^C\fR and then a second time as a META character like \fBM-^C\fR.
2131 The former is the binding for \fBvi\fR input mode, whereas the latter is the
2132 binding for \fBvi\fR command mode. Once in command mode all key sequences that
2133 the user types that they don't explicitly start with an ESCAPE or a META key,
2134 have their first key secretly converted to a META character before the key
2135 sequence is looked up in the key binding table. Thus, once in command mode,
2136 when you type the letter i, for example, the tecla library actually looks up
2137 the binding for \fBM-i\fR.

2334 The following are the key bindings that are defined in \fBvi\fR command mode,
2335 this being specified by them all starting with a META character. As mentioned
2336 above, once in command mode the initial meta character is optional. For
2337 example, you might enter command mode by typing ESCAPE, and then press 'H'
2338 twice to move the cursor two positions to the left. Both 'H' characters get
2339 quietly converted to \fBM-h\fR before being compared to the key binding table,
2340 the first one because ESCAPE followed by a character is always converted to the
2341 equivalent META character, and the second because command mode was already
2342 active.

3551 Note that \fB^I\fR is what the TAB key generates.
3552 .SS "Entering Repeat Counts"
3553 .LP
3554 Many of the key binding functions described previously, take an optional count,
3555 typed in before the target key sequence. This is interpreted as a repeat count
3556 by most bindings. A notable exception is the goto-column binding, which
3557 interprets the count as a column number.
3558 .sp
3559 .LP
3560 By default you can specify this count argument by pressing the META key while
3561 typing in the numeric count. This relies on the digit-argument action being
3562 bound to 'META-0', 'META-1' etc. Once any one of these bindings has been
3563 activated, you can optionally take your finger off the META key to type in the
3564 rest of the number, since every numeric digit thereafter is treated as part of
3565 the number, unless it is preceded by the literal-next binding. As soon as a
3566 non-digit, or literal digit key is pressed the repeat count is terminated and
3567 either causes the just typed character to be added to the line that many times,
3568 or causes the next key binding function to be given that argument.
3569 .sp
3570 .LP
3571 For example, in \fBemacs\fR mode, typing:
3572 .sp
3573 .in +2
3574 .nf
3575 M-12a
3576 .fi
3577 .in -2
3578 
3579 .sp
3580 .LP
3581 causes the letter 'a' to be added to the line 12 times, whereas
3582 .sp
3583 .in +2
3584 .nf
3585 M-4M-c
3586 .fi
3587 .in -2
3588 
3589 .sp
3590 .LP
3591 Capitalizes the next 4 words.
3592 .sp
3593 .LP
3594 In \fBvi\fR command mode the meta modifier is automatically added to all
3595 characters typed in, so to enter a count in \fBvi\fR command-mode, just
3596 involves typing in the number, just as it does in the \fBvi\fR editor itself.
3597 So for example, in vi command mode, typing:
3598 .sp
3599 .in +2
3600 .nf
3601 4w2x
3602 .fi
3603 .in -2
3604 
3605 .sp
3606 .LP
3607 moves the cursor four words to the right, then deletes two characters.
3608 .sp
3609 .LP
3610 You can also bind digit-argument to other key sequences. If these end in a
3611 numeric digit, that digit gets appended to the current repeat count. If it
3612 doesn't end in a numeric digit, a new repeat count is started with a value of
3613 zero, and can be completed by typing in the number, after letting go of the key
3614 which triggered the digit-argument action.
