157 Everytime a terminal object gets created, extension scripts specified via
158 the \f(CW\*(C`perl\*(C'\fR resource are loaded and associated with it.
159 .PP
160 Scripts are compiled in a 'use strict' and 'use utf8' environment, and
161 thus must be encoded as \s-1UTF\-8\s0.
162 .PP
163 Each script will only ever be loaded once, even in @@RXVT_NAME@@d, where
164 scripts will be shared (but not enabled) for all terminals.

166 .IX Header "PREPACKAGED EXTENSIONS"
167 This section describes the extensions delivered with this release. You can
168 find them in \fI@@RXVT_LIBDIR@@/urxvt/perl/\fR.
169 .PP
170 You can activate them like this:

175 .IP "selection (enabled by default)" 4
176 .IX Item "selection (enabled by default)"
177 (More) intelligent selection. This extension tries to be more intelligent
178 when the user extends selections (double\-click and further clicks). Right
179 now, it tries to select words, urls and complete shell-quoted
180 arguments, which is very convenient, too, if your \fIls\fR supports
181 \&\f(CW\*(C`\-\-quoting\-style=shell\*(C'\fR.
182 .Sp
183 A double-click usually selects the word under the cursor, further clicks
184 will enlarge the selection.
185 .Sp
186 The selection works by trying to match a number of regexes and displaying
187 them in increasing order of length. You can add your own regexes by
188 specifying resources of the form:
189 .Sp
190 .Vb 3
191 \& URxvt.selection.pattern-0: perl-regex
192 \& URxvt.selection.pattern-1: perl-regex
193 \& ...
194 .Ve
195 .Sp
196 The index number (0, 1...) must not have any holes, and each regex must
197 contain at least one pair of capturing parentheses, which will be used for
198 the match. For example, the followign adds a regex that matches everything
199 between two vertical bars:
200 .Sp
201 .Vb 1
202 \& URxvt.selection.pattern-0: \e\e|([^|]+)\e\e|
203 .Ve
204 .Sp
205 You can look at the source of the selection extension to see more
206 interesting uses, such as parsing a line from beginning to end.
207 .Sp
208 This extension also offers the following bindable keyboard command:
209 .RS 4
210 .IP "rot13" 4
211 .IX Item "rot13"
212 Rot\-13 the selection when activated. Used via keyboard trigger:

220 .IP "option-popup (enabled by default)" 4
221 .IX Item "option-popup (enabled by default)"
222 Binds a popup menu to Ctrl\-Button2 that lets you toggle (some) options at
223 runtime.
224 .IP "selection-popup (enabled by default)" 4
225 .IX Item "selection-popup (enabled by default)"
226 Binds a popup menu to Ctrl\-Button3 that lets you convert the selection
227 text into various other formats/action (such as uri unescaping, perl
228 evalution, web-browser starting etc.), depending on content.
229 .IP "searchable\-scrollback<hotkey> (enabled by default)" 4
230 .IX Item "searchable-scrollback<hotkey> (enabled by default)"
231 Adds regex search functionality to the scrollback buffer, triggered
232 by a hotkey (default: \f(CW\*(C`M\-s\*(C'\fR). While in search mode, normal terminal
233 input/output is suspended and a regex is displayed at the bottom of the
234 screen.
235 .Sp
236 Inputting characters appends them to the regex and continues incremental
237 search. \f(CW\*(C`BackSpace\*(C'\fR removes a character from the regex, \f(CW\*(C`Up\*(C'\fR and \f(CW\*(C`Down\*(C'\fR
238 search upwards/downwards in the scrollback buffer, \f(CW\*(C`End\*(C'\fR jumps to the
239 bottom. \f(CW\*(C`Escape\*(C'\fR leaves search mode and returns to the point where search
240 was started, while \f(CW\*(C`Enter\*(C'\fR or \f(CW\*(C`Return\*(C'\fR stay at the current position and
241 additionally stores the first match in the current line into the primary
242 selection.
243 .IP "selection-autotransform" 4
244 .IX Item "selection-autotransform"
245 This selection allows you to do automatic transforms on a selection
246 whenever a selection is made.
247 .Sp
248 It works by specifying perl snippets (most useful is a single \f(CW\*(C`s///\*(C'\fR
249 operator) that modify \f(CW$_\fR as resources:
250 .Sp
251 .Vb 3
252 \& URxvt.selection-autotransform.0: transform
253 \& URxvt.selection-autotransform.1: transform
254 \& ...
255 .Ve
256 .Sp
257 For example, the following will transform selections of the form
258 \&\f(CW\*(C`filename:number\*(C'\fR, often seen in compiler messages, into \f(CW\*(C`vi +$filename
259 $word\*(C'\fR:
260 .Sp
261 .Vb 1
262 \& URxvt.selection-autotransform.0: s/^(\e\eS+):(\e\ed+):?$/vi +$2 \e\eQ$1\e\eE\e\ex0d/
263 .Ve
264 .Sp
265 And this example matches the same,but replaces it with vi-commands you can
266 paste directly into your (vi :) editor:
267 .Sp
268 .Vb 1
269 \& URxvt.selection-autotransform.0: s/^(S+):(d+):?$/\e\ex1b:e \e\eQ$1\e\eE\e\ex0d:$2\e\ex0d/
270 .Ve
271 .IP "mark-urls" 4
272 .IX Item "mark-urls"
273 Uses per-line display filtering (\f(CW\*(C`on_line_update\*(C'\fR) to underline urls and
274 make them clickable. When middle\-clicked, the program specified in the
275 resource \f(CW\*(C`urlLauncher\*(C'\fR (default \f(CW\*(C`x\-www\-browser\*(C'\fR) will be started with
276 the \s-1URL\s0 as first argument.
277 .IP "block-graphics-to-ascii" 4
278 .IX Item "block-graphics-to-ascii"
279 A not very useful example of filtering all text output to the terminal,
280 by replacing all line-drawing characters (U+2500 .. U+259F) by a
281 similar-looking ascii character.
282 .IP "digital-clock" 4
283 .IX Item "digital-clock"
284 Displays a digital clock using the built-in overlay.
285 .IP "example-refresh-hooks" 4
286 .IX Item "example-refresh-hooks"
287 Displays a very simple digital clock in the upper right corner of the
288 window. Illustrates overwriting the refresh callbacks to create your own
289 overlays or changes.

292 .Sh "General \s-1API\s0 Considerations"
293 .IX Subsection "General API Considerations"
294 All objects (such as terminals, time watchers etc.) are typical
295 reference-to-hash objects. The hash can be used to store anything you
296 like. All members starting with an underscore (such as \f(CW\*(C`_ptr\*(C'\fR or
297 \&\f(CW\*(C`_hook\*(C'\fR) are reserved for internal uses and \fB\s-1MUST\s0 \s-1NOT\s0\fR be accessed or
298 modified).
299 .PP
300 When objects are destroyed on the \*(C+ side, the perl object hashes are
301 emptied, so its best to store related objects such as time watchers and
302 the like inside the terminal object so they get destroyed as soon as the
303 terminal is destroyed.
304 .PP
305 Argument names also often indicate the type of a parameter. Here are some
306 hints on what they mean:
307 .IP "$text" 4
308 .IX Item "$text"
309 Rxvt-unicodes special way of encoding text, where one \*(L"unicode\*(R" character
310 always represents one screen cell. See ROW_t for a discussion of this format.
311 .IP "$string" 4
312 .IX Item "$string"
313 A perl text string, with an emphasis on \fItext\fR. It can store all unicode
314 characters and is to be distinguished with text encoded in a specific
315 encoding (often locale\-specific) and binary data.
316 .IP "$octets" 4
317 .IX Item "$octets"
318 Either binary data or \- more common \- a text string encoded in a
319 locale-specific way.
320 .Sh "Extension Objects"
321 .IX Subsection "Extension Objects"
322 Very perl extension is a perl class. A separate perl object is created
323 for each terminal and each extension and passed as the first parameter to
324 hooks. So extensions can use their \f(CW$self\fR object without having to think
325 about other extensions, with the exception of methods and members that
326 begin with an underscore character \f(CW\*(C`_\*(C'\fR: these are reserved for internal
327 use.
328 .PP
329 Although it isn't a \f(CW\*(C`urxvt::term\*(C'\fR object, you can call all methods of the
330 \&\f(CW\*(C`urxvt::term\*(C'\fR class on this object.
331 .PP
332 It has the following methods and data members:
333 .ie n .IP "$urxvt_term = $self\->{term}" 4
334 .el .IP "$urxvt_term = \f(CW$self\fR\->{term}" 4
335 .IX Item "$urxvt_term = $self->{term}"
336 Returns the \f(CW\*(C`urxvt::term\*(C'\fR object associated with this instance of the
337 extension. This member \fImust not\fR be changed in any way.
338 .ie n .IP "$self\->enable ($hook_name => $cb\fR, [$hook_name => \f(CW$cb..])" 4
339 .el .IP "$self\->enable ($hook_name => \f(CW$cb\fR, [$hook_name => \f(CW$cb\fR..])" 4
340 .IX Item "$self->enable ($hook_name => $cb, [$hook_name => $cb..])"
341 Dynamically enable the given hooks (named without the \f(CW\*(C`on_\*(C'\fR prefix) for
342 this extension, replacing any previous hook. This is useful when you want
343 to overwrite time-critical hooks only temporarily.
344 .ie n .IP "$self\->disable ($hook_name[, $hook_name..])" 4
345 .el .IP "$self\->disable ($hook_name[, \f(CW$hook_name\fR..])" 4
346 .IX Item "$self->disable ($hook_name[, $hook_name..])"
347 Dynamically disable the given hooks.
348 .Sh "Hooks"
349 .IX Subsection "Hooks"
350 The following subroutines can be declared in extension files, and will be
351 called whenever the relevant event happens.
352 .PP
353 The first argument passed to them is an extension oject as described in
354 the in the \f(CW\*(C`Extension Objects\*(C'\fR section.
355 .PP
356 \&\fBAll\fR of these hooks must return a boolean value. If it is true, then the
357 event counts as being \fIconsumed\fR, and the invocation of other hooks is
358 skipped, and the relevant action might not be carried out by the \*(C+ code.
359 .PP
360 \&\fIWhen in doubt, return a false value (preferably \f(CI\*(C`()\*(C'\fI).\fR
361 .ie n .IP "on_init $term" 4
362 .el .IP "on_init \f(CW$term\fR" 4
363 .IX Item "on_init $term"
364 Called after a new terminal object has been initialized, but before
365 windows are created or the command gets run. Most methods are unsafe to
366 call or deliver senseless data, as terminal size and other characteristics
367 have not yet been determined. You can safely query and change resources,
368 though.
369 .ie n .IP "on_reset $term" 4
370 .el .IP "on_reset \f(CW$term\fR" 4
371 .IX Item "on_reset $term"
372 Called after the screen is \*(L"reset\*(R" for any reason, such as resizing or
373 control sequences. Here is where you can react on changes to size-related
374 variables.
375 .ie n .IP "on_start $term" 4
376 .el .IP "on_start \f(CW$term\fR" 4
377 .IX Item "on_start $term"
378 Called at the very end of initialisation of a new terminal, just before
379 returning to the mainloop.
380 .ie n .IP "on_sel_make $term\fR, \f(CW$eventtime" 4
381 .el .IP "on_sel_make \f(CW$term\fR, \f(CW$eventtime\fR" 4
382 .IX Item "on_sel_make $term, $eventtime"
383 Called whenever a selection has been made by the user, but before the
384 selection text is copied, so changes to the beginning, end or type of the
385 selection will be honored.
386 .Sp
387 Returning a true value aborts selection making by urxvt, in which case you
388 have to make a selection yourself by calling \f(CW\*(C`$term\->selection_grab\*(C'\fR.
389 .ie n .IP "on_sel_grab $term\fR, \f(CW$eventtime" 4
390 .el .IP "on_sel_grab \f(CW$term\fR, \f(CW$eventtime\fR" 4
391 .IX Item "on_sel_grab $term, $eventtime"
392 Called whenever a selection has been copied, but before the selection is
393 requested from the server. The selection text can be queried and changed
394 by calling \f(CW\*(C`$term\->selection\*(C'\fR.
395 .Sp
396 Returning a true value aborts selection grabbing. It will still be hilighted.
397 .ie n .IP "on_sel_extend $term" 4
398 .el .IP "on_sel_extend \f(CW$term\fR" 4
399 .IX Item "on_sel_extend $term"
400 Called whenever the user tries to extend the selection (e.g. with a double
401 click) and is either supposed to return false (normal operation), or
402 should extend the selection itelf and return true to suppress the built-in
403 processing. This can happen multiple times, as long as the callback
404 returns true, it will be called on every further click by the user and is
405 supposed to enlarge the selection more and more, if possible.
406 .Sp
407 See the \fIselection\fR example extension.
408 .ie n .IP "on_view_change $term\fR, \f(CW$offset" 4
409 .el .IP "on_view_change \f(CW$term\fR, \f(CW$offset\fR" 4
410 .IX Item "on_view_change $term, $offset"
411 Called whenever the view offset changes, i..e the user or program
412 scrolls. Offset \f(CW0\fR means display the normal terminal, positive values
413 show this many lines of scrollback.
414 .ie n .IP "on_scroll_back $term\fR, \f(CW$lines\fR, \f(CW$saved" 4

416 .IX Item "on_scroll_back $term, $lines, $saved"
417 Called whenever lines scroll out of the terminal area into the scrollback
418 buffer. \f(CW$lines\fR is the number of lines scrolled out and may be larger
419 than the scroll back buffer or the terminal.
420 .Sp
421 It is called before lines are scrolled out (so rows 0 .. min ($lines \- 1,
422 \&\f(CW$nrow\fR \- 1) represent the lines to be scrolled out). \f(CW$saved\fR is the total
423 number of lines that will be in the scrollback buffer.
424 .ie n .IP "on_osc_seq $term\fR, \f(CW$string" 4
425 .el .IP "on_osc_seq \f(CW$term\fR, \f(CW$string\fR" 4
426 .IX Item "on_osc_seq $term, $string"
427 Called whenever the \fB\s-1ESC\s0 ] 777 ; string \s-1ST\s0\fR command sequence (\s-1OSC\s0 =
428 operating system command) is processed. Cursor position and other state
429 information is up-to-date when this happens. For interoperability, the
430 string should start with the extension name and a colon, to distinguish
431 it from commands for other extensions, and this might be enforced in the
432 future.
433 .Sp

1102 This class implements timer watchers/events. Time is represented as a
1103 fractional number of seconds since the epoch. Example:
1104 .PP
1105 .Vb 8
1106 \& $term->{overlay} = $term->overlay (-1, 0, 8, 1, urxvt::OVERLAY_RSTYLE, 0);

1117 Create a new timer object in started state. It is scheduled to fire
1118 immediately.
1119 .ie n .IP "$timer = $timer\fR\->cb (sub { my ($timer) = \f(CW@_; ... })" 4

1134 Normally (and when \f(CW$interval\fR is \f(CW0\fR), the timer will automatically
1135 stop after it has fired once. If \f(CW$interval\fR is non\-zero, then the timer
1136 is automatically rescheduled at the given intervals.

1142 .el .IP "$timer = \f(CW$timer\fR\->start ($tstamp)" 4
1143 .IX Item "$timer = $timer->start ($tstamp)"
1144 Set the event trigger time to \f(CW$tstamp\fR and start the timer.
