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.

170 This section describes the extensions delivered with this release. You can

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

238 .IP "option-popup (enabled by default)" 4
239 .IX Item "option-popup (enabled by default)"
240 Binds a popup menu to Ctrl\-Button2 that lets you toggle (some) options at
241 runtime.
242 .Sp
243 Other extensions can extend this popup menu by pushing a code reference
244 onto \f(CW\*(C`@{ $term\-\*(C'\fR{option_popup_hook} }>, which gets called whenever the
245 popup is being displayed.
246 .Sp
247 It's sole argument is the popup menu, which can be modified. It should
248 either return nothing or a string, the initial boolean value and a code
249 reference. The string will be used as button text and the code reference
250 will be called when the toggle changes, with the new boolean value as
251 first argument.
252 .Sp
253 The following will add an entry \f(CW\*(C`myoption\*(C'\fR that changes
254 \&\f(CW\*(C`$self\-\*(C'\fR{myoption}>:
255 .Sp
256 .Vb 3

259 \& };
260 .Ve
261 .IP "selection-popup (enabled by default)" 4
262 .IX Item "selection-popup (enabled by default)"
263 Binds a popup menu to Ctrl\-Button3 that lets you convert the selection
264 text into various other formats/action (such as uri unescaping, perl
265 evaluation, web-browser starting etc.), depending on content.
266 .Sp
267 Other extensions can extend this popup menu by pushing a code reference
268 onto \f(CW\*(C`@{ $term\-\*(C'\fR{selection_popup_hook} }>, which gets called whenever the
269 popup is being displayed.
270 .Sp
271 It's sole argument is the popup menu, which can be modified. The selection
272 is in \f(CW$_\fR, which can be used to decide whether to add something or not.
273 It should either return nothing or a string and a code reference. The
274 string will be used as button text and the code reference will be called
275 when the button gets activated and should transform \f(CW$_\fR.
276 .Sp
277 The following will add an entry \f(CW\*(C`a to b\*(C'\fR that transforms all \f(CW\*(C`a\*(C'\fRs in
278 the selection to \f(CW\*(C`b\*(C'\fRs, but only if the selection currently contains any
279 \&\f(CW\*(C`a\*(C'\fRs:
280 .Sp
281 .Vb 4
282 \& push @{ $self->{term}{selection_popup_hook} }, sub {
283 \& /a/ ? ("a to be" => sub { s/a/b/g }

287 .IP "searchable\-scrollback<hotkey> (enabled by default)" 4
288 .IX Item "searchable-scrollback<hotkey> (enabled by default)"
289 Adds regex search functionality to the scrollback buffer, triggered
290 by a hotkey (default: \f(CW\*(C`M\-s\*(C'\fR). While in search mode, normal terminal
291 input/output is suspended and a regex is displayed at the bottom of the
292 screen.
293 .Sp
294 Inputting characters appends them to the regex and continues incremental
295 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
296 search upwards/downwards in the scrollback buffer, \f(CW\*(C`End\*(C'\fR jumps to the
297 bottom. \f(CW\*(C`Escape\*(C'\fR leaves search mode and returns to the point where search
298 was started, while \f(CW\*(C`Enter\*(C'\fR or \f(CW\*(C`Return\*(C'\fR stay at the current position and
299 additionally stores the first match in the current line into the primary
300 selection if the \f(CW\*(C`Shift\*(C'\fR modifier is active.
301 .Sp
302 The regex defaults to \*(L"(?i)\*(R", resulting in a case-insensitive search. To
303 get a case-sensitive search you can delete this prefix using \f(CW\*(C`BackSpace\*(C'\fR
304 or simply use an uppercase character which removes the \*(L"(?i)\*(R" prefix.
305 .Sp
306 See perlre for more info about perl regular expression syntax.
307 .IP "readline (enabled by default)" 4
308 .IX Item "readline (enabled by default)"
309 A support package that tries to make editing with readline easier. At
310 the moment, it reacts to clicking shift-left mouse button by trying to
311 move the text cursor to this position. It does so by generating as many
312 cursor-left or cursor-right keypresses as required (the this only works
313 for programs that correctly support wide characters).
314 .Sp
315 To avoid too many false positives, this is only done when:
316 .RS 4
317 .IP "\- the tty is in \s-1ICANON\s0 state." 4
318 .IX Item "- the tty is in ICANON state."
319 .PD 0
320 .IP "\- the text cursor is visible." 4
321 .IX Item "- the text cursor is visible."
322 .IP "\- the primary screen is currently being displayed." 4
323 .IX Item "- the primary screen is currently being displayed."
324 .IP "\- the mouse is on the same (multi\-row\-) line as the text cursor." 4
325 .IX Item "- the mouse is on the same (multi-row-) line as the text cursor."
326 .RE
327 .RS 4
328 .PD
329 .Sp
330 The normal selection mechanism isn't disabled, so quick successive clicks
331 might interfere with selection creation in harmless ways.
332 .RE
333 .IP "selection-autotransform" 4
334 .IX Item "selection-autotransform"
335 This selection allows you to do automatic transforms on a selection
336 whenever a selection is made.
337 .Sp
338 It works by specifying perl snippets (most useful is a single \f(CW\*(C`s///\*(C'\fR
339 operator) that modify \f(CW$_\fR as resources:
340 .Sp
341 .Vb 3
342 \& URxvt.selection-autotransform.0: transform
343 \& URxvt.selection-autotransform.1: transform
344 \& ...
345 .Ve
346 .Sp
347 For example, the following will transform selections of the form
348 \&\f(CW\*(C`filename:number\*(C'\fR, often seen in compiler messages, into \f(CW\*(C`vi +$filename
349 $word\*(C'\fR:
350 .Sp
351 .Vb 1
352 \& URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\e\ed+):?$/vi +$2 \e\eQ$1\e\eE\e\ex0d/
353 .Ve
354 .Sp
355 And this example matches the same,but replaces it with vi-commands you can
356 paste directly into your (vi :) editor:
357 .Sp
358 .Vb 1
359 \& URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\e\ed+):?$/:e \e\eQ$1\e\eE\e\ex0d:$2\e\ex0d/
360 .Ve
361 .Sp
362 Of course, this can be modified to suit your needs and your editor :)
363 .Sp
364 To expand the example above to typical perl error messages (\*(L"\s-1XXX\s0 at
365 \&\s-1FILENAME\s0 line \s-1YYY\s0.\*(R"), you need a slightly more elaborate solution:
366 .Sp
367 .Vb 2
368 \& URxvt.selection.pattern-0: ( at .*? line \e\ed+[,.])
369 \& URxvt.selection-autotransform.0: s/^ at (.*?) line (\e\ed+)[,.]$/:e \e\eQ$1\eE\e\ex0d:$2\e\ex0d/
370 .Ve
371 .Sp
372 The first line tells the selection code to treat the unchanging part of
373 every error message as a selection pattern, and the second line transforms
374 the message into vi commands to load the file.
375 .IP "tabbed" 4
376 .IX Item "tabbed"
377 This transforms the terminal into a tabbar with additional terminals, that
378 is, it implements what is commonly referred to as \*(L"tabbed terminal\*(R". The topmost line
379 displays a \*(L"[\s-1NEW\s0]\*(R" button, which, when clicked, will add a new tab, followed by one
380 button per tab.
381 .Sp
382 Clicking a button will activate that tab. Pressing \fBShift-Left\fR and
383 \&\fBShift-Right\fR will switch to the tab left or right of the current one,
384 while \fBShift-Down\fR creates a new tab.
385 .Sp
386 The tabbar itself can be configured similarly to a normal terminal, but
387 with a resource class of \f(CW\*(C`URxvt.tabbed\*(C'\fR. In addition, it supports the
388 following four resources (shown with defaults):
389 .Sp
390 .Vb 4
391 \& URxvt.tabbed.tabbar-fg: <colour-index, default 3>
392 \& URxvt.tabbed.tabbar-bg: <colour-index, default 0>
393 \& URxvt.tabbed.tab-fg: <colour-index, default 0>
394 \& URxvt.tabbed.tab-bg: <colour-index, default 1>
395 .Ve
396 .Sp
397 See \fI\s-1COLOR\s0 \s-1AND\s0 \s-1GRAPHICS\s0\fR in the @@RXVT_NAME@@(1) manpage for valid
398 indices.
399 .IP "matcher" 4
400 .IX Item "matcher"
401 Uses per-line display filtering (\f(CW\*(C`on_line_update\*(C'\fR) to underline text
402 matching a certain pattern and make it clickable. When clicked with the
403 mouse button specified in the \f(CW\*(C`matcher.button\*(C'\fR resource (default 2, or
404 middle), the program specified in the \f(CW\*(C`matcher.launcher\*(C'\fR resource
405 (default, the \f(CW\*(C`urlLauncher\*(C'\fR resource, \f(CW\*(C`sensible\-browser\*(C'\fR) will be started
406 with the matched text as first argument. The default configuration is
407 suitable for matching URLs and launching a web browser, like the
408 former \*(L"mark\-urls\*(R" extension.
409 .Sp
410 The default pattern to match URLs can be overridden with the
411 \&\f(CW\*(C`matcher.pattern.0\*(C'\fR resource, and additional patterns can be specified
412 with numbered patterns, in a manner similar to the \*(L"selection\*(R" extension.
413 The launcher can also be overridden on a per-pattern basis.
414 .Sp
415 It is possible to activate the most recently seen match from the keyboard.
416 Simply bind a keysym to \*(L"perl:matcher\*(R" as seen in the example below.

433 OnTheSpot editing in general, but it seems to work at leats for \s-1SCIM\s0 and
434 kinput2.

442 .IP "kuake<hotkey>" 4
443 .IX Item "kuake<hotkey>"
444 A very primitive quake-console-like extension. It was inspired by a
445 description of how the programs \f(CW\*(C`kuake\*(C'\fR and \f(CW\*(C`yakuake\*(C'\fR work: Whenever the
446 user presses a global accelerator key (by default \f(CW\*(C`F10\*(C'\fR), the terminal
447 will show or hide itself. Another press of the accelerator key will hide
448 or show it again.
449 .Sp
450 Initially, the window will not be shown when using this extension.
451 .Sp
452 This is useful if you need a single terminal thats not using any desktop
453 space most of the time but is quickly available at the press of a key.

462 This is basically a very small extension that dynamically changes the
463 background pixmap offset to the window position, in effect creating the
464 same effect as pseudo transparency with a custom pixmap. No scaling is
465 supported in this mode. Example:

483 .IX Item "remote-clipboard"
484 Somewhat of a misnomer, this extension adds two menu entries to the
485 selection popup that allows one ti run external commands to store the
486 selection somewhere and fetch it again.
487 .Sp
488 We use it to implement a \*(L"distributed selection mechanism\*(R", which just
489 means that one command uploads the file to a remote server, and another
490 reads it.
491 .Sp
492 The commands can be set using the \f(CW\*(C`URxvt.remote\-selection.store\*(C'\fR and
493 \&\f(CW\*(C`URxvt.remote\-selection.fetch\*(C'\fR resources. The first should read the
494 selection to store from \s-1STDIN\s0 (always in \s-1UTF\-8\s0), the second should provide
495 the selection data on \s-1STDOUT\s0 (also in \s-1UTF\-8\s0).
496 .Sp
497 The defaults (which are likely useless to you) use rsh and cat:
498 .Sp
499 .Vb 2

502 .Ve
503 .IP "selection-pastebin" 4
504 .IX Item "selection-pastebin"
505 This is a little rarely useful extension that Uploads the selection as
506 textfile to a remote site (or does other things). (The implementation is
507 not currently secure for use in a multiuser environment as it writes to
508 \&\fI/tmp\fR directly.).
509 .Sp
510 It listens to the \f(CW\*(C`selection\-pastebin:remote\-pastebin\*(C'\fR keyboard command,
511 i.e.
512 .Sp
513 .Vb 1
514 \& URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
515 .Ve
516 .Sp
517 Pressing this combination runs a command with \f(CW\*(C`%\*(C'\fR replaced by the name of
518 the textfile. This command can be set via a resource:
519 .Sp
520 .Vb 1
521 \& URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
522 .Ve
523 .Sp
524 And the default is likely not useful to anybody but the few people around
525 here :)
526 .Sp
527 The name of the textfile is the hex encoded md5 sum of the selection, so
528 the same content should lead to the same filename.
529 .Sp
530 After a successful upload the selection will be replaced by the text given
531 in the \f(CW\*(C`selection\-pastebin\-url\*(C'\fR resource (again, the % is the placeholder
532 for the filename):
533 .Sp

539 the double \f(CW\*(C`/\*(C'\fR characters as comment start. Use \f(CW\*(C`\e057\e057\*(C'\fR instead,
540 which works regardless of wether xrdb is used to parse the resource file

551 All objects (such as terminals, time watchers etc.) are typical
552 reference-to-hash objects. The hash can be used to store anything you
553 like. All members starting with an underscore (such as \f(CW\*(C`_ptr\*(C'\fR or
554 \&\f(CW\*(C`_hook\*(C'\fR) are reserved for internal uses and \fB\s-1MUST\s0 \s-1NOT\s0\fR be accessed or
555 modified).
556 .PP
557 When objects are destroyed on the \*(C+ side, the perl object hashes are
558 emptied, so its best to store related objects such as time watchers and
559 the like inside the terminal object so they get destroyed as soon as the
560 terminal is destroyed.
561 .PP
562 Argument names also often indicate the type of a parameter. Here are some
563 hints on what they mean:
564 .IP "$text" 4

570 A perl text string, with an emphasis on \fItext\fR. It can store all unicode

575 Either binary data or \- more common \- a text string encoded in a
576 locale-specific way.
577 .Sh "Extension Objects"
578 .IX Subsection "Extension Objects"
579 Every perl extension is a perl class. A separate perl object is created
580 for each terminal, and each terminal has its own set of extenion objects,
581 which are passed as the first parameter to hooks. So extensions can use
582 their \f(CW$self\fR object without having to think about clashes with other
583 extensions or other terminals, with the exception of methods and members
584 that begin with an underscore character \f(CW\*(C`_\*(C'\fR: these are reserved for
585 internal use.
586 .PP
587 Although it isn't a \f(CW\*(C`urxvt::term\*(C'\fR object, you can call all methods of the
588 \&\f(CW\*(C`urxvt::term\*(C'\fR class on this object.

623 windows are created or the command gets run. Most methods are unsafe to
624 call or deliver senseless data, as terminal size and other characteristics
625 have not yet been determined. You can safely query and change resources
