157 Every time 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

164 scripts will be shared (but not enabled) for all terminals.

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:

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 following 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 Another example: Programs I use often output \*(L"absolute path: \*(R" at the
212 beginning of a line when they process multiple files. The following
213 pattern matches the filename (note, there is a single space at the very
214 end):
215 .Sp
216 .Vb 1
217 \& URxvt.selection.pattern-0: ^(/[^:]+):\e
218 .Ve
219 .Sp
220 You can look at the source of the selection extension to see more
221 interesting uses, such as parsing a line from beginning to end.

235 .IP "option-popup (enabled by default)" 4
236 .IX Item "option-popup (enabled by default)"
237 Binds a popup menu to Ctrl\-Button2 that lets you toggle (some) options at
238 runtime.
239 .Sp
240 Other extensions can extend this popup menu by pushing a code reference
241 onto \f(CW\*(C`@{ $term\-\*(C'\fR{option_popup_hook} }>, which gets called whenever the
242 popup is being displayed.
243 .Sp
244 It's sole argument is the popup menu, which can be modified. It should
245 either return nothing or a string, the initial boolean value and a code
246 reference. The string will be used as button text and the code reference
247 will be called when the toggle changes, with the new boolean value as
248 first argument.
249 .Sp
250 The following will add an entry \f(CW\*(C`myoption\*(C'\fR that changes
251 \&\f(CW\*(C`$self\-\*(C'\fR{myoption}>:
252 .Sp
253 .Vb 3
254 \& push @{ $self->{term}{option_popup_hook} }, sub {
255 \& ("my option" => $myoption, sub { $self->{myoption} = $_[0] })
256 \& };
257 .Ve
258 .IP "selection-popup (enabled by default)" 4
259 .IX Item "selection-popup (enabled by default)"
260 Binds a popup menu to Ctrl\-Button3 that lets you convert the selection
261 text into various other formats/action (such as uri unescaping, perl
262 evaluation, web-browser starting etc.), depending on content.
263 .Sp
264 Other extensions can extend this popup menu by pushing a code reference
265 onto \f(CW\*(C`@{ $term\-\*(C'\fR{selection_popup_hook} }>, which gets called whenever the
266 popup is being displayed.
267 .Sp
268 It's sole argument is the popup menu, which can be modified. The selection
269 is in \f(CW$_\fR, which can be used to decide whether to add something or not.
270 It should either return nothing or a string and a code reference. The
271 string will be used as button text and the code reference will be called
272 when the button gets activated and should transform \f(CW$_\fR.
273 .Sp
274 The following will add an entry \f(CW\*(C`a to b\*(C'\fR that transforms all \f(CW\*(C`a\*(C'\fRs in
275 the selection to \f(CW\*(C`b\*(C'\fRs, but only if the selection currently contains any
276 \&\f(CW\*(C`a\*(C'\fRs:
277 .Sp
278 .Vb 4
279 \& push @{ $self->{term}{selection_popup_hook} }, sub {
280 \& /a/ ? ("a to be" => sub { s/a/b/g }
281 \& : ()
282 \& };
283 .Ve
284 .IP "searchable\-scrollback<hotkey> (enabled by default)" 4
285 .IX Item "searchable-scrollback<hotkey> (enabled by default)"
286 Adds regex search functionality to the scrollback buffer, triggered
287 by a hotkey (default: \f(CW\*(C`M\-s\*(C'\fR). While in search mode, normal terminal
288 input/output is suspended and a regex is displayed at the bottom of the
289 screen.
290 .Sp
291 Inputting characters appends them to the regex and continues incremental
292 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
293 search upwards/downwards in the scrollback buffer, \f(CW\*(C`End\*(C'\fR jumps to the
294 bottom. \f(CW\*(C`Escape\*(C'\fR leaves search mode and returns to the point where search
295 was started, while \f(CW\*(C`Enter\*(C'\fR or \f(CW\*(C`Return\*(C'\fR stay at the current position and
296 additionally stores the first match in the current line into the primary
297 selection.
298 .Sp
299 The regex defaults to \*(L"(?i)\*(R", resulting in a case-insensitive search. To
300 get a case-sensitive search you can delete this prefix using \f(CW\*(C`BackSpace\*(C'\fR
301 or simply use an uppercase character which removes the \*(L"(?i)\*(R" prefix.
302 .Sp
303 See perlre for more info about perl regular expression syntax.
304 .IP "readline (enabled by default)" 4
305 .IX Item "readline (enabled by default)"
306 A support package that tries to make editing with readline easier. At
307 the moment, it reacts to clicking shift-left mouse button by trying to
308 move the text cursor to this position. It does so by generating as many
309 cursor-left or cursor-right keypresses as required (the this only works
310 for programs that correctly support wide characters).
311 .Sp
312 To avoid too many false positives, this is only done when:
313 .RS 4
314 .IP "\- the tty is in \s-1ICANON\s0 state." 4
315 .IX Item "- the tty is in ICANON state."
316 .PD 0
317 .IP "\- the text cursor is visible." 4
318 .IX Item "- the text cursor is visible."
319 .IP "\- the primary screen is currently being displayed." 4
320 .IX Item "- the primary screen is currently being displayed."
321 .IP "\- the mouse is on the same (multi\-row\-) line as the text cursor." 4
322 .IX Item "- the mouse is on the same (multi-row-) line as the text cursor."
323 .RE
324 .RS 4
325 .PD
326 .Sp
327 The normal selection mechanism isn't disabled, so quick successive clicks
328 might interfere with selection creation in harmless ways.
329 .RE
330 .IP "selection-autotransform" 4
331 .IX Item "selection-autotransform"
332 This selection allows you to do automatic transforms on a selection
333 whenever a selection is made.
334 .Sp
335 It works by specifying perl snippets (most useful is a single \f(CW\*(C`s///\*(C'\fR
336 operator) that modify \f(CW$_\fR as resources:
337 .Sp
338 .Vb 3
339 \& URxvt.selection-autotransform.0: transform
340 \& URxvt.selection-autotransform.1: transform
341 \& ...
342 .Ve
343 .Sp
344 For example, the following will transform selections of the form
345 \&\f(CW\*(C`filename:number\*(C'\fR, often seen in compiler messages, into \f(CW\*(C`vi +$filename
346 $word\*(C'\fR:
347 .Sp
348 .Vb 1
349 \& URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\e\ed+):?$/vi +$2 \e\eQ$1\e\eE\e\ex0d/
350 .Ve
351 .Sp
352 And this example matches the same,but replaces it with vi-commands you can
353 paste directly into your (vi :) editor:
354 .Sp
355 .Vb 1
356 \& URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\e\ed+):?$/:e \e\eQ$1\e\eE\e\ex0d:$2\e\ex0d/
357 .Ve
358 .Sp
359 Of course, this can be modified to suit your needs and your editor :)
360 .Sp
361 To expand the example above to typical perl error messages (\*(L"\s-1XXX\s0 at
362 \&\s-1FILENAME\s0 line \s-1YYY\s0.\*(R"), you need a slightly more elaborate solution:
363 .Sp
364 .Vb 2
365 \& URxvt.selection.pattern-0: ( at .*? line \e\ed+[,.])
366 \& URxvt.selection-autotransform.0: s/^ at (.*?) line (\e\ed+)[,.]$/:e \e\eQ$1\eE\e\ex0d:$2\e\ex0d/
367 .Ve
368 .Sp
369 The first line tells the selection code to treat the unchanging part of
370 every error message as a selection pattern, and the second line transforms
371 the message into vi commands to load the file.
372 .IP "tabbed" 4
373 .IX Item "tabbed"
374 This transforms the terminal into a tabbar with additional terminals, that
375 is, it implements what is commonly referred to as \*(L"tabbed terminal\*(R". The topmost line
376 displays a \*(L"[\s-1NEW\s0]\*(R" button, which, when clicked, will add a new tab, followed by one
377 button per tab.
378 .Sp
379 Clicking a button will activate that tab. Pressing \fBShift-Left\fR and
380 \&\fBShift-Right\fR will switch to the tab left or right of the current one,
381 while \fBShift-Down\fR creates a new tab.
382 .Sp
383 The tabbar itself can be configured similarly to a normal terminal, but
384 with a resource class of \f(CW\*(C`URxvt.tabbed\*(C'\fR. In addition, it supports the
385 following four resources (shown with defaults):
386 .Sp
387 .Vb 4
388 \& URxvt.tabbed.tabbar-fg: <colour-index, default 3>
389 \& URxvt.tabbed.tabbar-bg: <colour-index, default 0>
390 \& URxvt.tabbed.tab-fg: <colour-index, default 0>
391 \& URxvt.tabbed.tab-bg: <colour-index, default 1>
392 .Ve
393 .Sp
394 See \fI\s-1COLOR\s0 \s-1AND\s0 \s-1GRAPHICS\s0\fR in the @@RXVT_NAME@@(1) manpage for valid
395 indices.
396 .IP "matcher" 4
397 .IX Item "matcher"
398 Uses per-line display filtering (\f(CW\*(C`on_line_update\*(C'\fR) to underline text
399 matching a certain pattern and make it clickable. When clicked with the
400 mouse button specified in the \f(CW\*(C`matcher.button\*(C'\fR resource (default 2, or
401 middle), the program specified in the \f(CW\*(C`matcher.launcher\*(C'\fR resource
402 (default, the \f(CW\*(C`urlLauncher\*(C'\fR resource, \f(CW\*(C`sensible\-browser\*(C'\fR) will be started
403 with the matched text as first argument. The default configuration is
404 suitable for matching URLs and launching a web browser, like the
405 former \*(L"mark\-urls\*(R" extension.
406 .Sp
407 The default pattern to match URLs can be overridden with the
408 \&\f(CW\*(C`matcher.pattern.0\*(C'\fR resource, and additional patterns can be specified
409 with numbered patterns, in a manner similar to the \*(L"selection\*(R" extension.
410 The launcher can also be overridden on a per-pattern basis.
411 .Sp
412 Example configuration:

425 This (experimental) perl extension implements OnTheSpot editing. It does
426 not work perfectly, and some input methods don't seem to work well with
427 OnTheSpot editing in general, but it seems to work at leats for \s-1SCIM\s0 and
428 kinput2.

436 .IP "kuake<hotkey>" 4
437 .IX Item "kuake<hotkey>"
438 A very primitive quake-console-like extension. It was inspired by a
439 description of how the programs \f(CW\*(C`kuake\*(C'\fR and \f(CW\*(C`yakuake\*(C'\fR work: Whenever the
440 user presses a global accelerator key (by default \f(CW\*(C`F10\*(C'\fR), the terminal
441 will show or hide itself. Another press of the accelerator key will hide
442 or show it again.
443 .Sp
444 Initially, the window will not be shown when using this extension.
445 .Sp
446 This is useful if you need a single terminal thats not using any desktop
447 space most of the time but is quickly available at the press of a key.
448 .Sp
449 The accelerator key is grabbed regardless of any modifiers, so this
450 extension will actually grab a physical key just for this function.
451 .Sp
452 If you want a quake-like animation, tell your window manager to do so
453 (fvwm can do it).
454 .IP "automove-background" 4
455 .IX Item "automove-background"
456 This is basically a very small extension that dynamically changes the

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

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

532 \&\fINote to xrdb users:\fR xrdb uses the C preprocessor, which might interpret
533 the double \f(CW\*(C`/\*(C'\fR characters as comment start. Use \f(CW\*(C`\e057\e057\*(C'\fR instead,
534 which works regardless of wether xrdb is used to parse the resource file

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

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