# create a file grab_test in $HOME: |
| 6 |
|
| 7 |
sub on_sel_grab { |
| 8 |
warn "you selected ", $_[0]->selection; |
| 9 |
() |
| 10 |
} |
| 11 |
|
| 12 |
# start a rxvt using it: |
| 13 |
|
| 14 |
rxvt --perl-lib $HOME -pe grab_test |
| 15 |
|
| 16 |
DESCRIPTION |
| 17 |
Everytime a terminal object gets created, scripts specified via the |
| 18 |
"perl" resource are loaded and associated with it. |
| 19 |
|
| 20 |
Scripts are compiled in a 'use strict' and 'use utf8' environment, and |
| 21 |
thus must be encoded as UTF-8. |
| 22 |
|
| 23 |
Each script will only ever be loaded once, even in rxvtd, where scripts |
| 24 |
will be shared (but not enabled) for all terminals. |
| 25 |
|
| 26 |
Prepackaged Extensions |
| 27 |
This section describes the extensiosn delivered with this version. You |
| 28 |
can find them in /opt/rxvt/lib/urxvt/perl/. |
| 29 |
|
| 30 |
You can activate them like this: |
| 31 |
|
| 32 |
rxvt -pe <extensionname> |
| 33 |
|
| 34 |
selection |
| 35 |
Intelligent selection. This etxension tries to be more intelligent |
| 36 |
when the user extends selections (double-click). |
| 37 |
|
| 38 |
It also offers the following bindable event: |
| 39 |
|
| 40 |
rot13 |
| 41 |
Rot-13 the selection when activated. Used via keyboard trigger: |
| 42 |
|
| 43 |
URxvt.keysym.C-M-r: perl:selection:rot13 |
| 44 |
|
| 45 |
digital-clock |
| 46 |
Displays a digital clock using the built-in overlay. |
| 47 |
|
| 48 |
example-refresh-hooks |
| 49 |
Displays a very simple digital clock in the upper right corner of |
| 50 |
the window. Illustrates overwriting the refresh callbacks to create |
| 51 |
your own overlays or changes. |
| 52 |
|
| 53 |
General API Considerations |
| 54 |
All objects (such as terminals, time watchers etc.) are typical |
| 55 |
reference-to-hash objects. The hash can be used to store anything you |
| 56 |
like. All members starting with an underscore (such as "_ptr" or |
| 57 |
"_hook") are reserved for internal uses and MUST NOT be accessed or |
| 58 |
modified). |
| 59 |
|
| 60 |
When objects are destroyed on the C++ side, the perl object hashes are |
| 61 |
emptied, so its best to store related objects such as time watchers and |
| 62 |
the like inside the terminal object so they get destroyed as soon as the |
| 63 |
terminal is destroyed. |
| 64 |
|
| 65 |
Hooks |
| 66 |
The following subroutines can be declared in loaded scripts, and will be |
| 67 |
called whenever the relevant event happens. |
| 68 |
|
| 69 |
The first argument passed to them is an object private to each terminal |
| 70 |
and extension package. You can call all "urxvt::term" methods on it, but |
| 71 |
its not a real "urxvt::term" object. Instead, the real "urxvt::term" |
| 72 |
object that is shared between all packages is stored in the "term" |
| 73 |
member. |
| 74 |
|
| 75 |
All of them must return a boolean value. If it is true, then the event |
| 76 |
counts as being *consumed*, and the invocation of other hooks is |
| 77 |
skipped, and the relevant action might not be carried out by the C++ |
| 78 |
code. |
| 79 |
|
| 80 |
When in doubt, return a false value (preferably "()"). |
| 81 |
|
| 82 |
on_init $term |
| 83 |
Called after a new terminal object has been initialized, but before |
| 84 |
windows are created or the command gets run. |
| 85 |
|
| 86 |
on_reset $term |
| 87 |
Called after the screen is "reset" for any reason, such as resizing |
| 88 |
or control sequences. Here is where you can react on changes to |
| 89 |
size-related variables. |
| 90 |
|
| 91 |
on_start $term |
| 92 |
Called at the very end of initialisation of a new terminal, just |
| 93 |
before returning to the mainloop. |
| 94 |
|
| 95 |
on_sel_make $term, $eventtime |
| 96 |
Called whenever a selection has been made by the user, but before |
| 97 |
the selection text is copied, so changes to the beginning, end or |
| 98 |
type of the selection will be honored. |
| 99 |
|
| 100 |
Returning a true value aborts selection making by urxvt, in which |
| 101 |
case you have to make a selection yourself by calling |
| 102 |
"$term->selection_grab". |
| 103 |
|
| 104 |
on_sel_grab $term, $eventtime |
| 105 |
Called whenever a selection has been copied, but before the |
| 106 |
selection is requested from the server. The selection text can be |
| 107 |
queried and changed by calling "$term->selection". |
| 108 |
|
| 109 |
Returning a true value aborts selection grabbing. It will still be |
| 110 |
hilighted. |
| 111 |
|
| 112 |
on_sel_extend $term |
| 113 |
Called whenever the user tries to extend the selection (e.g. with a |
| 114 |
double click) and is either supposed to return false (normal |
| 115 |
operation), or should extend the selection itelf and return true to |
| 116 |
suppress the built-in processing. |
| 117 |
|
| 118 |
See the selection example extension. |
| 119 |
|
| 120 |
on_focus_in $term |
| 121 |
Called whenever the window gets the keyboard focus, before urxvt |
| 122 |
does focus in processing. |
| 123 |
|
| 124 |
on_focus_out $term |
| 125 |
Called wheneever the window loses keyboard focus, before urxvt does |
| 126 |
focus out processing. |
| 127 |
|
| 128 |
on_view_change $term, $offset |
| 129 |
Called whenever the view offset changes, i..e the user or program |
| 130 |
scrolls. Offset 0 means display the normal terminal, positive values |
| 131 |
show this many lines of scrollback. |
| 132 |
|
| 133 |
on_scroll_back $term, $lines, $saved |
| 134 |
Called whenever lines scroll out of the terminal area into the |
| 135 |
scrollback buffer. $lines is the number of lines scrolled out and |
| 136 |
may be larger than the scroll back buffer or the terminal. |
| 137 |
|
| 138 |
It is called before lines are scrolled out (so rows 0 .. min ($lines |
| 139 |
- 1, $nrow - 1) represent the lines to be scrolled out). $saved is |
| 140 |
the total number of lines that will be in the scrollback buffer. |
| 141 |
|
| 142 |
on_tty_activity $term *NYI* |
| 143 |
Called whenever the program(s) running in the urxvt window send |
| 144 |
output. |
| 145 |
|
| 146 |
on_refresh_begin $term |
| 147 |
Called just before the screen gets redrawn. Can be used for overlay |
| 148 |
or similar effects by modify terminal contents in refresh_begin, and |
| 149 |
restoring them in refresh_end. The built-in overlay and selection |
| 150 |
display code is run after this hook, and takes precedence. |
| 151 |
|
| 152 |
on_refresh_end $term |
| 153 |
Called just after the screen gets redrawn. See "on_refresh_begin". |
| 154 |
|
| 155 |
on_keyboard_command $term, $string |
| 156 |
Called whenever the user presses a key combination that has a |
| 157 |
"perl:string" action bound to it (see description of the keysym |
| 158 |
resource in the rxvt(1) manpage). |
| 159 |
|
| 160 |
Variables in the "urxvt" Package |
| 161 |
$urxvt::TERM |
| 162 |
The current terminal. Whenever a callback/Hook is bein executed, |
| 163 |
this variable stores the current "urxvt::term" object. |
| 164 |
|
| 165 |
Functions in the "urxvt" Package |
| 166 |
urxvt::fatal $errormessage |
| 167 |
Fatally aborts execution with the given error message. Avoid at all |
| 168 |
costs! The only time this is acceptable is when the terminal process |
| 169 |
starts up. |
| 170 |
|
| 171 |
urxvt::warn $string |
| 172 |
Calls "rxvt_warn" with the given string which should not include a |
| 173 |
newline. The module also overwrites the "warn" builtin with a |
| 174 |
function that calls this function. |
| 175 |
|
| 176 |
Using this function has the advantage that its output ends up in the |
| 177 |
correct place, e.g. on stderr of the connecting urxvtc client. |
| 178 |
|
| 179 |
$time = urxvt::NOW |
| 180 |
Returns the "current time" (as per the event loop). |
| 181 |
|
| 182 |
RENDITION |
| 183 |
Rendition bitsets contain information about colour, font, font styles |
| 184 |
and similar information for each screen cell. |
| 185 |
|
| 186 |
The following "macros" deal with changes in rendition sets. You should |
| 187 |
never just create a bitset, you should always modify an existing one, as |
| 188 |
they contain important information required for correct operation of |
| 189 |
rxvt-unicode. |
| 190 |
|
| 191 |
$rend = urxvt::DEFAULT_RSTYLE |
| 192 |
Returns the default rendition, as used when the terminal is starting |
| 193 |
up or being reset. Useful as a base to start when creating |
| 194 |
renditions. |
| 195 |
|
| 196 |
$rend = urxvt::OVERLAY_RSTYLE |
| 197 |
Return the rendition mask used for overlays by default. |
| 198 |
|
| 199 |
$rendbit = urxvt::RS_Bold, RS_Italic, RS_Blink, RS_RVid, RS_Uline |
| 200 |
Return the bit that enabled bold, italic, blink, reverse-video and |
| 201 |
underline, respectively. To enable such a style, just logically OR |
| 202 |
it into the bitset. |
| 203 |
|
| 204 |
$foreground = urxvt::GET_BASEFG $rend |
| 205 |
$background = urxvt::GET_BASEBG $rend |
| 206 |
Return the foreground/background colour index, respectively. |
| 207 |
|
| 208 |
$rend = urxvt::SET_FGCOLOR ($rend, $new_colour) |
| 209 |
$rend = urxvt::SET_BGCOLOR ($rend, $new_colour) |
| 210 |
Replace the foreground/background colour in the rendition mask with |
| 211 |
the specified one. |
| 212 |
|
| 213 |
$value = urxvt::GET_CUSTOM ($rend) |
| 214 |
Return the "custom" value: Every rendition has 5 bits for use by |
| 215 |
extensions. They can be set and changed as you like and are |
| 216 |
initially zero. |
| 217 |
|
| 218 |
$rend = urxvt::SET_CUSTOM ($rend, $new_value) |
| 219 |
Change the custom value. |
| 220 |
|
| 221 |
The "urxvt::term" Class |
| 222 |
$value = $term->resource ($name[, $newval]) |
| 223 |
Returns the current resource value associated with a given name and |
| 224 |
optionally sets a new value. Setting values is most useful in the |
| 225 |
"init" hook. Unset resources are returned and accepted as "undef". |
| 226 |
|
| 227 |
The new value must be properly encoded to a suitable character |
| 228 |
encoding before passing it to this method. Similarly, the returned |
| 229 |
value may need to be converted from the used encoding to text. |
| 230 |
|
| 231 |
Resource names are as defined in src/rsinc.h. Colours can be |
| 232 |
specified as resource names of the form "color+<index>", e.g. |
| 233 |
"color+5". (will likely change). |
| 234 |
|
| 235 |
Please note that resource strings will currently only be freed when |
| 236 |
the terminal is destroyed, so changing options frequently will eat |
| 237 |
memory. |
| 238 |
|
| 239 |
Here is a a likely non-exhaustive list of resource names, not all of |
| 240 |
which are supported in every build, please see the source to see the |
| 241 |

($row, $col) = $term->selection_mark ([$row, $col]) |
| 257 |
($row, $col) = $term->selection_beg ([$row, $col]) |
| 258 |
($row, $col) = $term->selection_end ([$row, $col]) |
| 259 |
Return the current values of the selection mark, begin or end |
| 260 |
positions, and optionally set them to new values. |
| 261 |
|
| 262 |
$success = $term->selection_grab ($eventtime) |
| 263 |
Try to request the primary selection from the server (for example, |
| 264 |
as set by the next method). |
| 265 |
|
| 266 |
$oldtext = $term->selection ([$newtext]) |
| 267 |
Return the current selection text and optionally replace it by |
| 268 |
$newtext. |
| 269 |
|
| 270 |
#=item $term->overlay ($x, $y, $text) # #Create a simple multi-line |
| 271 |
overlay box. See the next method for details. # #=cut |
| 272 |
|
| 273 |
sub urxvt::term::scr_overlay { die; my ($self, $x, $y, $text) = @_; |
| 274 |
|
| 275 |
my @lines = split /\n/, $text; |
| 276 |
|
| 277 |
my $w = 0; |
| 278 |
for (map $self->strwidth ($_), @lines) { |
| 279 |
$w = $_ if $w < $_; |
| 280 |
} |
| 281 |
|
| 282 |
$self->scr_overlay_new ($x, $y, $w, scalar @lines); |
| 283 |
$self->scr_overlay_set (0, $_, $lines[$_]) for 0.. $#lines; |
| 284 |
} |
| 285 |
|
| 286 |
$term->overlay ($x, $y, $width, $height[, $rstyle[, $border]]) |
| 287 |
Create a new (empty) overlay at the given position with the given |
| 288 |
width/height. $rstyle defines the initial rendition style (default: |
| 289 |
"OVERLAY_RSTYLE"). |
| 290 |
|
| 291 |
If $border is 2 (default), then a decorative border will be put |
| 292 |
around the box. |
| 293 |
|
| 294 |
If either $x or $y is negative, then this is counted from the |
| 295 |
right/bottom side, respectively. |
| 296 |
|
| 297 |
This method returns an urxvt::overlay object. The overlay will be |
| 298 |
visible as long as the perl object is referenced. |
| 299 |
|
| 300 |
The methods currently supported on "urxvt::overlay" objects are: |
| 301 |
|
| 302 |
$overlay->set ($x, $y, $text, $rend) |
| 303 |
Similar to "$term->ROW_t" and "$term->ROW_r" in that it puts |
| 304 |
text in rxvt-unicode's special encoding and an array of |
| 305 |
rendition values at a specific position inside the overlay. |
| 306 |
|
| 307 |
$overlay->hide |
| 308 |
If visible, hide the overlay, but do not destroy it. |
| 309 |
|
| 310 |
$overlay->show |
| 311 |
If hidden, display the overlay again. |
| 312 |
|
| 313 |
$cellwidth = $term->strwidth $string |
| 314 |
Returns the number of screen-cells this string would need. Correctly |
| 315 |
accounts for wide and combining characters. |
| 316 |
|
| 317 |
$octets = $term->locale_encode $string |
| 318 |
Convert the given text string into the corresponding locale |
| 319 |
encoding. |
| 320 |
|
| 321 |
$string = $term->locale_decode $octets |
| 322 |
Convert the given locale-encoded octets into a perl string. |
| 323 |
|
| 324 |
$term->tt_write ($octets) |
| 325 |
Write the octets given in $data to the tty (i.e. as program input). |
| 326 |
To pass characters instead of octets, you should convert your |
| 327 |
strings first to the locale-specific encoding using |
| 328 |
"$term->locale_encode". |
| 329 |
|
| 330 |
$nrow = $term->nrow |
| 331 |
$ncol = $term->ncol |
| 332 |
Return the number of rows/columns of the terminal window (i.e. as |
| 333 |
specified by "-geometry", excluding any scrollback). |
| 334 |
|
| 335 |
$nsaved = $term->nsaved |
| 336 |
Returns the number of lines in the scrollback buffer. |
| 337 |
|
| 338 |
$view_start = $term->view_start ([$newvalue]) |
| 339 |
Returns the negative row number of the topmost line. Minimum value |
| 340 |
is 0, which displays the normal terminal contents. Larger values |
| 341 |
scroll this many lines into the scrollback buffer. |
| 342 |
|
| 343 |
$term->want_refresh |
| 344 |
Requests a screen refresh. At the next opportunity, rxvt-unicode |
| 345 |
will compare the on-screen display with its stored representation. |
| 346 |
If they differ, it redraws the differences. |
| 347 |
|
| 348 |
Used after changing terminal contents to display them. |
| 349 |
|
| 350 |
$text = $term->ROW_t ($row_number[, $new_text[, $start_col]]) |
| 351 |
Returns the text of the entire row with number $row_number. Row 0 is |
| 352 |
the topmost terminal line, row "$term->$ncol-1" is the bottommost |
| 353 |
terminal line. The scrollback buffer starts at line -1 and extends |
| 354 |
to line "-$term->nsaved". Nothing will be returned if a nonexistent |
| 355 |
line is requested. |
| 356 |
|
| 357 |
If $new_text is specified, it will replace characters in the current |
| 358 |
line, starting at column $start_col (default 0), which is useful to |
| 359 |
replace only parts of a line. The font index in the rendition will |
| 360 |
automatically be updated. |
| 361 |
|
| 362 |
$text is in a special encoding: tabs and wide characters that use |
| 363 |
more than one cell when displayed are padded with urxvt::NOCHAR |
| 364 |
characters ("chr 65535"). Characters with combining characters and |
| 365 |
other characters that do not fit into the normal tetx encoding will |
| 366 |
be replaced with characters in the private use area. |
| 367 |
|
| 368 |
You have to obey this encoding when changing text. The advantage is |
| 369 |
that "substr" and similar functions work on screen cells and not on |
| 370 |
characters. |
| 371 |
|
| 372 |
The methods "$term->special_encode" and "$term->special_decode" can |
| 373 |
be used to convert normal strings into this encoding and vice versa. |
| 374 |
|
| 375 |
$rend = $term->ROW_r ($row_number[, $new_rend[, $start_col]]) |
| 376 |
Like "$term->ROW_t", but returns an arrayref with rendition bitsets. |
| 377 |
Rendition bitsets contain information about colour, font, font |
| 378 |
styles and similar information. See also "$term->ROW_t". |
| 379 |
|
| 380 |
When setting rendition, the font mask will be ignored. |
| 381 |
|
| 382 |
See the section on RENDITION, above. |
| 383 |
|
| 384 |
$length = $term->ROW_l ($row_number[, $new_length]) |
| 385 |
Returns the number of screen cells that are in use ("the line |
| 386 |
length"). Unlike the urxvt core, this returns "$term->ncol" if the |
| 387 |
line is joined with the following one. |
| 388 |
|
| 389 |
$bool = $term->is_longer ($row_number) |
| 390 |
Returns true if the row is part of a multiple-row logical "line" |
| 391 |
(i.e. joined with the following row), which means all characters are |
| 392 |
in use and it is continued on the next row (and possibly a |
| 393 |
continuation of the previous row(s)). |
| 394 |
|
| 395 |
$line = $term->line ($row_number) |
| 396 |
Create and return a new "urxvt::line" object that stores information |
| 397 |
about the logical line that row $row_number is part of. It supports |
| 398 |
the following methods: |
| 399 |
|
| 400 |
$text = $line->t |
| 401 |
Returns the full text of the line, similar to "ROW_t" |
| 402 |
|
| 403 |
$rend = $line->r |
| 404 |
Returns the full rendition array of the line, similar to "ROW_r" |
| 405 |
|
| 406 |
$length = $line->l |
| 407 |
Returns the length of the line in cells, similar to "ROW_l". |
| 408 |
|
| 409 |
$rownum = $line->beg |
| 410 |
$rownum = $line->end |
| 411 |
Return the row number of the first/last row of the line, |
| 412 |
respectively. |
| 413 |
|
| 414 |
$offset = $line->offset_of ($row, $col) |
| 415 |
Returns the character offset of the given row|col pair within |
| 416 |
the logical line. |
| 417 |
|
| 418 |
($row, $col) = $line->coord_of ($offset) |
| 419 |
Translates a string offset into terminal coordinates again. |
| 420 |

($row, $col) = $line->coord_of ($offset) =item $text = |
| 422 |
$term->special_encode $string |
| 423 |
Converts a perl string into the special encoding used by |
| 424 |
rxvt-unicode, where one character corresponds to one screen cell. |
| 425 |
See "$term->ROW_t" for details. |
| 426 |
|
| 427 |
$string = $term->special_decode $text |
| 428 |
Converts rxvt-unicodes text reprsentation into a perl string. See |
| 429 |
"$term->ROW_t" for details. |
| 430 |

| 431 |
The "urxvt::timer" Class |
| 432 |
This class implements timer watchers/events. Time is represented as a |
| 433 |
fractional number of seconds since the epoch. Example: |
| 434 |
|
| 435 |
$term->{overlay} = $term->overlay (-1, 0, 8, 1, urxvt::OVERLAY_RSTYLE, 0); |
| 436 |
$term->{timer} = urxvt::timer |
| 437 |
->new |
| 438 |
->interval (1) |
| 439 |
->cb (sub { |
| 440 |
$term->{overlay}->set (0, 0, |
| 441 |
sprintf "%2d:%02d:%02d", (localtime urxvt::NOW)[2,1,0]); |
| 442 |
}); |
| 443 |
|
| 444 |
$timer = new urxvt::timer |
| 445 |
Create a new timer object in started state. It is scheduled to fire |
| 446 |
immediately. |
| 447 |
|
| 448 |
$timer = $timer->cb (sub { my ($timer) = @_; ... }) |
| 449 |
Set the callback to be called when the timer triggers. |
| 450 |
|
| 451 |
$tstamp = $timer->at |
| 452 |
Return the time this watcher will fire next. |
| 453 |
|
| 454 |
$timer = $timer->set ($tstamp) |
| 455 |
Set the time the event is generated to $tstamp. |
| 456 |
|
| 457 |
$timer = $timer->interval ($interval) |
| 458 |
Normally (and when $interval is 0), the timer will automatically |
| 459 |
stop after it has fired once. If $interval is non-zero, then the |
| 460 |
timer is automatically rescheduled at the given intervals. |
| 461 |
|
| 462 |
$timer = $timer->start |
| 463 |
Start the timer. |
| 464 |
|
| 465 |
$timer = $timer->start ($tstamp) |
| 466 |
Set the event trigger time to $tstamp and start the timer. |
| 467 |
|
| 468 |
$timer = $timer->stop |
| 469 |
Stop the timer. |
| 470 |
|
| 471 |
The "urxvt::iow" Class |
| 472 |
This class implements io watchers/events. Example: |
| 473 |
|
| 474 |
$term->{socket} = ... |
| 475 |
$term->{iow} = urxvt::iow |
| 476 |
->new |
| 477 |
->fd (fileno $term->{socket}) |
| 478 |
->events (1) # wait for read data |
| 479 |
->start |
| 480 |
->cb (sub { |
| 481 |
my ($iow, $revents) = @_; |
| 482 |
# $revents must be 1 here, no need to check |
| 483 |
sysread $term->{socket}, my $buf, 8192 |
| 484 |
or end-of-file; |
| 485 |
}); |
| 486 |
|
| 487 |
$iow = new urxvt::iow |
| 488 |
Create a new io watcher object in stopped state. |
| 489 |
|
| 490 |
$iow = $iow->cb (sub { my ($iow, $reventmask) = @_; ... }) |
| 491 |
Set the callback to be called when io events are triggered. |
| 492 |
$reventmask is a bitset as described in the "events" method. |
| 493 |
|
| 494 |
$iow = $iow->fd ($fd) |
| 495 |
Set the filedescriptor (not handle) to watch. |
| 496 |
|
| 497 |
$iow = $iow->events ($eventmask) |
| 498 |
Set the event mask to watch. Bit #0 (value 1) enables watching for |
| 499 |
read data, Bit #1 (value 2) enables watching for write data. |
| 500 |
|
| 501 |
$iow = $iow->start |
| 502 |
Start watching for requested events on the given handle. |
| 503 |
|
| 504 |
$iow = $iow->stop |
| 505 |
Stop watching for events on the given filehandle. |
| 506 |
|
| 507 |
ENVIRONMENT |
| 508 |
URXVT_PERL_VERBOSITY |
| 509 |
This variable controls the verbosity level of the perl extension. Higher |
| 510 |
numbers indicate more verbose output. |
| 511 |
|
| 512 |
0 - only fatal messages |
| 513 |
3 - script loading and management |
| 514 |
10 - all events received |
| 515 |
