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.

167 This section describes the extensions delivered with this release. You can
168 find them in \fI@@RXVT_LIBDIR@@/urxvt/perl/\fR.

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

226 .IP "option-popup (enabled by default)" 4
227 .IX Item "option-popup (enabled by default)"
228 Binds a popup menu to Ctrl\-Button2 that lets you toggle (some) options at
229 runtime.
230 .IP "selection-popup (enabled by default)" 4
231 .IX Item "selection-popup (enabled by default)"
232 Binds a popup menu to Ctrl\-Button3 that lets you convert the selection
233 text into various other formats/action (such as uri unescaping, perl
234 evaluation, web-browser starting etc.), depending on content.
235 .Sp
236 Other extensions can extend this popup menu by pushing a code reference
237 onto \f(CW\*(C`@{ $term\-\*(C'\fR{selection_popup_hook} }>, that is called whenever the
238 popup is displayed.
239 .Sp
240 It's sole argument is the popup menu, which can be modified. The selection
241 is in \f(CW$_\fR, which can be used to decide wether to add something or not.
242 It should either return nothing or a string and a code reference. The
243 string will be used as button text and the code reference will be called
244 when the button gets activated and should transform \f(CW$_\fR.
245 .Sp
246 The following will add an entry \f(CW\*(C`a to b\*(C'\fR that transforms all \f(CW\*(C`a\*(C'\fRs in
247 the selection to \f(CW\*(C`b\*(C'\fRs, but only if the selection currently contains any
248 \&\f(CW\*(C`a\*(C'\fRs:
249 .Sp
250 .Vb 4
251 \& push @{ $self->{term}{selection_popup_hook} }, sub {
252 \& /a/ ? ("a to be" => sub { s/a/b/g }
253 \& : ()
254 \& };
255 .Ve
256 .IP "searchable\-scrollback<hotkey> (enabled by default)" 4
257 .IX Item "searchable-scrollback<hotkey> (enabled by default)"
258 Adds regex search functionality to the scrollback buffer, triggered
259 by a hotkey (default: \f(CW\*(C`M\-s\*(C'\fR). While in search mode, normal terminal
260 input/output is suspended and a regex is displayed at the bottom of the
261 screen.
262 .Sp
263 Inputting characters appends them to the regex and continues incremental
264 search. \f(CW\*(C`BackSpace\*(C'\fR removes a character from the regex, \f(CW\*(C`Up\*(C'\fR and \f(CW\*(C`Down\*(C'\fR
265 search upwards/downwards in the scrollback buffer, \f(CW\*(C`End\*(C'\fR jumps to the
266 bottom. \f(CW\*(C`Escape\*(C'\fR leaves search mode and returns to the point where search
267 was started, while \f(CW\*(C`Enter\*(C'\fR or \f(CW\*(C`Return\*(C'\fR stay at the current position and
268 additionally stores the first match in the current line into the primary
269 selection.
270 .IP "selection-autotransform" 4
271 .IX Item "selection-autotransform"
272 This selection allows you to do automatic transforms on a selection
273 whenever a selection is made.
274 .Sp
275 It works by specifying perl snippets (most useful is a single \f(CW\*(C`s///\*(C'\fR
276 operator) that modify \f(CW$_\fR as resources:
277 .Sp
278 .Vb 3
279 \& URxvt.selection-autotransform.0: transform
280 \& URxvt.selection-autotransform.1: transform
281 \& ...
282 .Ve
283 .Sp
284 For example, the following will transform selections of the form
285 \&\f(CW\*(C`filename:number\*(C'\fR, often seen in compiler messages, into \f(CW\*(C`vi +$filename
286 $word\*(C'\fR:
287 .Sp
288 .Vb 1
289 \& URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\e\ed+):?$/vi +$2 \e\eQ$1\e\eE\e\ex0d/
290 .Ve
291 .Sp
292 And this example matches the same,but replaces it with vi-commands you can
293 paste directly into your (vi :) editor:
294 .Sp
295 .Vb 1
296 \& URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\e\ed+):?$/:e \e\eQ$1\e\eE\e\ex0d:$2\e\ex0d/
297 .Ve
298 .Sp
299 Of course, this can be modified to suit your needs and your editor :)
300 .Sp
301 To expand the example above to typical perl error messages (\*(L"\s-1XXX\s0 at
302 \&\s-1FILENAME\s0 line \s-1YYY\s0.\*(R"), you need a slightly more elaborate solution:
303 .Sp
304 .Vb 2
305 \& URxvt.selection.pattern-0: ( at .*? line \e\ed+[,.])
306 \& URxvt.selection-autotransform.0: s/^ at (.*?) line (\e\ed+)[,.]$/:e \e\eQ$1\eE\e\ex0d:$2\e\ex0d/
307 .Ve
308 .Sp
309 The first line tells the selection code to treat the unchanging part of
310 every error message as a selection pattern, and the second line transforms
311 the message into vi commands to load the file.
312 .IP "readline" 4
313 .IX Item "readline"
314 A support package that tries to make editing with readline easier. At the
315 moment, it reacts to clicking with the left mouse button by trying to
316 move the text cursor to this position. It does so by generating as many
317 cursor-left or cursor-right keypresses as required (the this only works
318 for programs that correctly support wide characters).
319 .Sp
320 It only works when clicking into the same line (possibly extended over
321 multiple rows) as the text cursor and on the primary screen, to reduce the
322 risk of misinterpreting. The normal selection isn't disabled, so quick
323 successive clicks might interfere with selection creation in harmless
324 ways.
325 .IP "tabbed" 4
326 .IX Item "tabbed"
327 This transforms the terminal into a tabbar with additional terminals, that
328 is, it implements what is commonly refered to as \*(L"tabbed terminal\*(R". The topmost line
329 displays a \*(L"[\s-1NEW\s0]\*(R" button, which, when clicked, will add a new tab, followed by one
330 button per tab.
331 .Sp
332 Clicking a button will activate that tab. Pressing \fBShift-Left\fR and
333 \&\fBShift-Right\fR will switch to the tab left or right of the current one,
334 while \fBShift-Down\fR creates a new tab.
335 .IP "mark-urls" 4
336 .IX Item "mark-urls"
337 Uses per-line display filtering (\f(CW\*(C`on_line_update\*(C'\fR) to underline urls and
338 make them clickable. When middle\-clicked, the program specified in the
339 resource \f(CW\*(C`urlLauncher\*(C'\fR (default \f(CW\*(C`x\-www\-browser\*(C'\fR) will be started with
340 the \s-1URL\s0 as first argument.
341 .IP "automove-background" 4
342 .IX Item "automove-background"
343 This is basically a one-line extension that dynamically changes the background pixmap offset
344 to the window position, in effect creating the same effect as pseudo transparency with
345 a custom pixmap. No scaling is supported in this mode. Exmaple:
346 .Sp
347 .Vb 1
348 \& @@RXVT_NAME@@ -pixmap background.xpm -pe automove-background
349 .Ve
350 .IP "block-graphics-to-ascii" 4
351 .IX Item "block-graphics-to-ascii"
352 A not very useful example of filtering all text output to the terminal,
353 by replacing all line-drawing characters (U+2500 .. U+259F) by a
354 similar-looking ascii character.
355 .IP "digital-clock" 4
356 .IX Item "digital-clock"
357 Displays a digital clock using the built-in overlay.
358 .IP "example-refresh-hooks" 4
359 .IX Item "example-refresh-hooks"
360 Displays a very simple digital clock in the upper right corner of the
361 window. Illustrates overwriting the refresh callbacks to create your own
362 overlays or changes.
363 .IP "selection-pastebin" 4
364 .IX Item "selection-pastebin"
365 This is a little rarely useful extension that Uploads the selection as
366 textfile to a remote site (or does other things). (The implementation is
367 not currently secure for use in a multiuser environment as it writes to
368 \&\fI/tmp\fR directly.).
369 .Sp
370 It listens to the \f(CW\*(C`selection\-pastebin:remote\-pastebin\*(C'\fR keyboard command,
371 i.e.
372 .Sp
373 .Vb 1
374 \& URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
375 .Ve
376 .Sp
377 Pressing this combination runs a command with \f(CW\*(C`%\*(C'\fR replaced by the name of
378 the textfile. This command can be set via a resource:
379 .Sp
380 .Vb 1
381 \& URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
382 .Ve
383 .Sp
384 And the default is likely not useful to anybody but the few people around
385 here :)
386 .Sp
387 The name of the textfile is the hex encoded md5 sum of the selection, so
388 the same content should lead to the same filename.
389 .Sp
390 After a successful upload the selection will be replaced by the text given
391 in the \f(CW\*(C`selection\-pastebin\-url\*(C'\fR resource (again, the % is the placeholder
392 for the filename):
393 .Sp
394 .Vb 1
395 \& URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/%
396 .Ve
397 .SH "API DOCUMENTATION"
398 .IX Header "API DOCUMENTATION"
399 .Sh "General \s-1API\s0 Considerations"
400 .IX Subsection "General API Considerations"
401 All objects (such as terminals, time watchers etc.) are typical
402 reference-to-hash objects. The hash can be used to store anything you
403 like. All members starting with an underscore (such as \f(CW\*(C`_ptr\*(C'\fR or
404 \&\f(CW\*(C`_hook\*(C'\fR) are reserved for internal uses and \fB\s-1MUST\s0 \s-1NOT\s0\fR be accessed or
405 modified).
406 .PP
407 When objects are destroyed on the \*(C+ side, the perl object hashes are
408 emptied, so its best to store related objects such as time watchers and
409 the like inside the terminal object so they get destroyed as soon as the
410 terminal is destroyed.
411 .PP
412 Argument names also often indicate the type of a parameter. Here are some
413 hints on what they mean:
414 .IP "$text" 4
415 .IX Item "$text"
416 Rxvt-unicodes special way of encoding text, where one \*(L"unicode\*(R" character
417 always represents one screen cell. See ROW_t for a discussion of this format.
418 .IP "$string" 4
419 .IX Item "$string"
420 A perl text string, with an emphasis on \fItext\fR. It can store all unicode
421 characters and is to be distinguished with text encoded in a specific
422 encoding (often locale\-specific) and binary data.
423 .IP "$octets" 4
424 .IX Item "$octets"
425 Either binary data or \- more common \- a text string encoded in a
426 locale-specific way.
427 .Sh "Extension Objects"
428 .IX Subsection "Extension Objects"
429 Very perl extension is a perl class. A separate perl object is created
430 for each terminal and each extension and passed as the first parameter to
431 hooks. So extensions can use their \f(CW$self\fR object without having to think
432 about other extensions, with the exception of methods and members that
433 begin with an underscore character \f(CW\*(C`_\*(C'\fR: these are reserved for internal
434 use.
435 .PP
436 Although it isn't a \f(CW\*(C`urxvt::term\*(C'\fR object, you can call all methods of the
437 \&\f(CW\*(C`urxvt::term\*(C'\fR class on this object.
438 .PP
439 It has the following methods and data members:
440 .ie n .IP "$urxvt_term = $self\->{term}" 4
441 .el .IP "$urxvt_term = \f(CW$self\fR\->{term}" 4
442 .IX Item "$urxvt_term = $self->{term}"
443 Returns the \f(CW\*(C`urxvt::term\*(C'\fR object associated with this instance of the
444 extension. This member \fImust not\fR be changed in any way.
445 .ie n .IP "$self\->enable ($hook_name => $cb\fR, [$hook_name => \f(CW$cb..])" 4
446 .el .IP "$self\->enable ($hook_name => \f(CW$cb\fR, [$hook_name => \f(CW$cb\fR..])" 4
447 .IX Item "$self->enable ($hook_name => $cb, [$hook_name => $cb..])"
448 Dynamically enable the given hooks (named without the \f(CW\*(C`on_\*(C'\fR prefix) for
449 this extension, replacing any previous hook. This is useful when you want
450 to overwrite time-critical hooks only temporarily.
451 .ie n .IP "$self\->disable ($hook_name[, $hook_name..])" 4
452 .el .IP "$self\->disable ($hook_name[, \f(CW$hook_name\fR..])" 4

470 .IX Item "on_init $term"
471 Called after a new terminal object has been initialized, but before
472 windows are created or the command gets run. Most methods are unsafe to
473 call or deliver senseless data, as terminal size and other characteristics
474 have not yet been determined. You can safely query and change resources
475 and options, though. For many purposes the \f(CW\*(C`on_start\*(C'\fR hook is a better
476 place.
477 .ie n .IP "on_start $term" 4
478 .el .IP "on_start \f(CW$term\fR" 4
479 .IX Item "on_start $term"
480 Called at the very end of initialisation of a new terminal, just before

490 .IX Item "on_reset $term"
491 Called after the screen is \*(L"reset\*(R" for any reason, such as resizing or

493 variables.
494 .ie n .IP "on_child_start $term\fR, \f(CW$pid" 4

507 selection text is copied, so changes to the beginning, end or type of the
508 selection will be honored.
509 .Sp
510 Returning a true value aborts selection making by urxvt, in which case you
511 have to make a selection yourself by calling \f(CW\*(C`$term\->selection_grab\*(C'\fR.

515 Called whenever a selection has been copied, but before the selection is
516 requested from the server. The selection text can be queried and changed
517 by calling \f(CW\*(C`$term\->selection\*(C'\fR.

521 .el .IP "on_sel_extend \f(CW$term\fR" 4
522 .IX Item "on_sel_extend $term"
523 Called whenever the user tries to extend the selection (e.g. with a double
524 click) and is either supposed to return false (normal operation), or
525 should extend the selection itelf and return true to suppress the built-in
526 processing. This can happen multiple times, as long as the callback
527 returns true, it will be called on every further click by the user and is
528 supposed to enlarge the selection more and more, if possible.

539 .IX Item "on_scroll_back $term, $lines, $saved"
540 Called whenever lines scroll out of the terminal area into the scrollback
541 buffer. \f(CW$lines\fR is the number of lines scrolled out and may be larger
542 than the scroll back buffer or the terminal.
543 .Sp
544 It is called before lines are scrolled out (so rows 0 .. min ($lines \- 1,
545 \&\f(CW$nrow\fR \- 1) represent the lines to be scrolled out). \f(CW$saved\fR is the total
546 number of lines that will be in the scrollback buffer.

550 Called whenever the \fB\s-1ESC\s0 ] 777 ; string \s-1ST\s0\fR command sequence (\s-1OSC\s0 =
551 operating system command) is processed. Cursor position and other state
552 information is up-to-date when this happens. For interoperability, the
553 string should start with the extension name and a colon, to distinguish
554 it from commands for other extensions, and this might be enforced in the
555 future.
556 .Sp
557 Be careful not ever to trust (in a security sense) the data you receive,
558 as its source can not easily be controleld (e\-mail content, messages from
559 other users on the same system etc.).

561 .el .IP "on_add_lines \f(CW$term\fR, \f(CW$string\fR" 4
562 .IX Item "on_add_lines $term, $string"
563 Called whenever text is about to be output, with the text as argument. You
564 can filter/change and output the text yourself by returning a true value
565 and calling \f(CW\*(C`$term\->scr_add_lines\*(C'\fR yourself. Please note that this
566 might be very slow, however, as your hook is called for \fBall\fR text being
567 output.
568 .ie n .IP "on_tt_write $term\fR, \f(CW$octets" 4
569 .el .IP "on_tt_write \f(CW$term\fR, \f(CW$octets\fR" 4

574 .el .IP "on_line_update \f(CW$term\fR, \f(CW$row\fR" 4
575 .IX Item "on_line_update $term, $row"
576 Called whenever a line was updated or changed. Can be used to filter
577 screen output (e.g. underline urls or other useless stuff). Only lines
578 that are being shown will be filtered, and, due to performance reasons,
579 not always immediately.
580 .Sp
581 The row number is always the topmost row of the line if the line spans
582 multiple rows.
583 .Sp
584 Please note that, if you change the line, then the hook might get called
585 later with the already-modified line (e.g. if unrelated parts change), so
586 you cannot just toggle rendition bits, but only set them.

591 or similar effects by modify terminal contents in refresh_begin, and
592 restoring them in refresh_end. The built-in overlay and selection display
593 code is run after this hook, and takes precedence.

793 \&\f(CW\*(C`AnyEvent\*(C'\fR module \- any module using it will work inside urxvt without
794 further programming. The only exception is that you cannot wait on
795 condition variables, but non-blocking condvar use is ok. What this means
796 is that you cannot use blocking APIs, but the non-blocking variant should
797 work.
