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

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"

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 }

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 "readline (enabled by default)" 4
271 .IX Item "readline (enabled by default)"
272 A support package that tries to make editing with readline easier. At the
273 moment, it reacts to clicking with the left mouse button by trying to
274 move the text cursor to this position. It does so by generating as many
275 cursor-left or cursor-right keypresses as required (the this only works
276 for programs that correctly support wide characters).
277 .Sp
278 To avoid too many false positives, this is only done when:
279 .RS 4
280 .IP "\- the mouse is on the same (multi\-row\-) line as the text cursor." 4
281 .IX Item "- the mouse is on the same (multi-row-) line as the text cursor."
282 .PD 0
283 .IP "\- the primary screen is currently being displayed." 4
284 .IX Item "- the primary screen is currently being displayed."
285 .IP "\- the text cursor is visible." 4
286 .IX Item "- the text cursor is visible."
287 .RE
288 .RS 4
289 .PD
290 .Sp
291 The normal selection mechanism isn't disabled, so quick successive clicks
292 might interfere with selection creation in harmless ways.
293 .RE
294 .IP "selection-autotransform" 4
295 .IX Item "selection-autotransform"
296 This selection allows you to do automatic transforms on a selection
297 whenever a selection is made.
298 .Sp
299 It works by specifying perl snippets (most useful is a single \f(CW\*(C`s///\*(C'\fR
300 operator) that modify \f(CW$_\fR as resources:
301 .Sp
302 .Vb 3
303 \& URxvt.selection-autotransform.0: transform
304 \& URxvt.selection-autotransform.1: transform
305 \& ...
306 .Ve
307 .Sp
308 For example, the following will transform selections of the form
309 \&\f(CW\*(C`filename:number\*(C'\fR, often seen in compiler messages, into \f(CW\*(C`vi +$filename
310 $word\*(C'\fR:
311 .Sp
312 .Vb 1
313 \& URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\e\ed+):?$/vi +$2 \e\eQ$1\e\eE\e\ex0d/
314 .Ve
315 .Sp
316 And this example matches the same,but replaces it with vi-commands you can
317 paste directly into your (vi :) editor:
318 .Sp
319 .Vb 1
320 \& URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\e\ed+):?$/:e \e\eQ$1\e\eE\e\ex0d:$2\e\ex0d/
321 .Ve
322 .Sp
323 Of course, this can be modified to suit your needs and your editor :)
324 .Sp
325 To expand the example above to typical perl error messages (\*(L"\s-1XXX\s0 at
326 \&\s-1FILENAME\s0 line \s-1YYY\s0.\*(R"), you need a slightly more elaborate solution:
327 .Sp
328 .Vb 2
329 \& URxvt.selection.pattern-0: ( at .*? line \e\ed+[,.])
330 \& URxvt.selection-autotransform.0: s/^ at (.*?) line (\e\ed+)[,.]$/:e \e\eQ$1\eE\e\ex0d:$2\e\ex0d/
331 .Ve
332 .Sp
333 The first line tells the selection code to treat the unchanging part of
334 every error message as a selection pattern, and the second line transforms
335 the message into vi commands to load the file.
336 .IP "tabbed" 4
337 .IX Item "tabbed"
338 This transforms the terminal into a tabbar with additional terminals, that
339 is, it implements what is commonly refered to as \*(L"tabbed terminal\*(R". The topmost line
340 displays a \*(L"[\s-1NEW\s0]\*(R" button, which, when clicked, will add a new tab, followed by one
341 button per tab.
342 .Sp
343 Clicking a button will activate that tab. Pressing \fBShift-Left\fR and
344 \&\fBShift-Right\fR will switch to the tab left or right of the current one,
345 while \fBShift-Down\fR creates a new tab.
346 .IP "mark-urls" 4
347 .IX Item "mark-urls"
348 Uses per-line display filtering (\f(CW\*(C`on_line_update\*(C'\fR) to underline urls and
349 make them clickable. When middle\-clicked, the program specified in the
350 resource \f(CW\*(C`urlLauncher\*(C'\fR (default \f(CW\*(C`x\-www\-browser\*(C'\fR) will be started with
351 the \s-1URL\s0 as first argument.
352 .IP "automove-background" 4
353 .IX Item "automove-background"
354 This is basically a one-line extension that dynamically changes the background pixmap offset
355 to the window position, in effect creating the same effect as pseudo transparency with
356 a custom pixmap. No scaling is supported in this mode. Exmaple:
357 .Sp
358 .Vb 1
359 \& @@RXVT_NAME@@ -pixmap background.xpm -pe automove-background
360 .Ve
361 .IP "block-graphics-to-ascii" 4
362 .IX Item "block-graphics-to-ascii"
363 A not very useful example of filtering all text output to the terminal,
364 by replacing all line-drawing characters (U+2500 .. U+259F) by a
365 similar-looking ascii character.
366 .IP "digital-clock" 4
367 .IX Item "digital-clock"
368 Displays a digital clock using the built-in overlay.
369 .IP "example-refresh-hooks" 4
370 .IX Item "example-refresh-hooks"
371 Displays a very simple digital clock in the upper right corner of the
372 window. Illustrates overwriting the refresh callbacks to create your own
373 overlays or changes.
374 .IP "selection-pastebin" 4
375 .IX Item "selection-pastebin"
376 This is a little rarely useful extension that Uploads the selection as
377 textfile to a remote site (or does other things). (The implementation is
378 not currently secure for use in a multiuser environment as it writes to
379 \&\fI/tmp\fR directly.).
380 .Sp
381 It listens to the \f(CW\*(C`selection\-pastebin:remote\-pastebin\*(C'\fR keyboard command,
382 i.e.
383 .Sp
384 .Vb 1
385 \& URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
386 .Ve
387 .Sp
388 Pressing this combination runs a command with \f(CW\*(C`%\*(C'\fR replaced by the name of
389 the textfile. This command can be set via a resource:
390 .Sp
391 .Vb 1
392 \& URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
393 .Ve
394 .Sp
395 And the default is likely not useful to anybody but the few people around
396 here :)
397 .Sp
398 The name of the textfile is the hex encoded md5 sum of the selection, so
399 the same content should lead to the same filename.
400 .Sp
401 After a successful upload the selection will be replaced by the text given
402 in the \f(CW\*(C`selection\-pastebin\-url\*(C'\fR resource (again, the % is the placeholder
403 for the filename):
404 .Sp
405 .Vb 1
406 \& URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/%
407 .Ve

411 .IX Subsection "General API Considerations"
412 All objects (such as terminals, time watchers etc.) are typical
413 reference-to-hash objects. The hash can be used to store anything you
414 like. All members starting with an underscore (such as \f(CW\*(C`_ptr\*(C'\fR or
415 \&\f(CW\*(C`_hook\*(C'\fR) are reserved for internal uses and \fB\s-1MUST\s0 \s-1NOT\s0\fR be accessed or
416 modified).
417 .PP
418 When objects are destroyed on the \*(C+ side, the perl object hashes are
419 emptied, so its best to store related objects such as time watchers and
420 the like inside the terminal object so they get destroyed as soon as the
421 terminal is destroyed.
422 .PP
423 Argument names also often indicate the type of a parameter. Here are some
424 hints on what they mean:
425 .IP "$text" 4
426 .IX Item "$text"
427 Rxvt-unicodes special way of encoding text, where one \*(L"unicode\*(R" character
428 always represents one screen cell. See ROW_t for a discussion of this format.
429 .IP "$string" 4
430 .IX Item "$string"
431 A perl text string, with an emphasis on \fItext\fR. It can store all unicode
432 characters and is to be distinguished with text encoded in a specific
433 encoding (often locale\-specific) and binary data.
434 .IP "$octets" 4
435 .IX Item "$octets"
436 Either binary data or \- more common \- a text string encoded in a
437 locale-specific way.
438 .Sh "Extension Objects"
439 .IX Subsection "Extension Objects"
440 Very perl extension is a perl class. A separate perl object is created
441 for each terminal and each extension and passed as the first parameter to
442 hooks. So extensions can use their \f(CW$self\fR object without having to think
443 about other extensions, with the exception of methods and members that
444 begin with an underscore character \f(CW\*(C`_\*(C'\fR: these are reserved for internal
445 use.
446 .PP
447 Although it isn't a \f(CW\*(C`urxvt::term\*(C'\fR object, you can call all methods of the
448 \&\f(CW\*(C`urxvt::term\*(C'\fR class on this object.
449 .PP
450 It has the following methods and data members:
451 .ie n .IP "$urxvt_term = $self\->{term}" 4
452 .el .IP "$urxvt_term = \f(CW$self\fR\->{term}" 4
453 .IX Item "$urxvt_term = $self->{term}"
454 Returns the \f(CW\*(C`urxvt::term\*(C'\fR object associated with this instance of the
455 extension. This member \fImust not\fR be changed in any way.
456 .ie n .IP "$self\->enable ($hook_name => $cb\fR, [$hook_name => \f(CW$cb..])" 4

482 Called after a new terminal object has been initialized, but before
483 windows are created or the command gets run. Most methods are unsafe to
484 call or deliver senseless data, as terminal size and other characteristics
485 have not yet been determined. You can safely query and change resources
486 and options, though. For many purposes the \f(CW\*(C`on_start\*(C'\fR hook is a better
487 place.

534 Called whenever the user tries to extend the selection (e.g. with a double
535 click) and is either supposed to return false (normal operation), or
536 should extend the selection itelf and return true to suppress the built-in
537 processing. This can happen multiple times, as long as the callback

550 .IX Item "on_scroll_back $term, $lines, $saved"
551 Called whenever lines scroll out of the terminal area into the scrollback
552 buffer. \f(CW$lines\fR is the number of lines scrolled out and may be larger
553 than the scroll back buffer or the terminal.
554 .Sp
555 It is called before lines are scrolled out (so rows 0 .. min ($lines \- 1,
556 \&\f(CW$nrow\fR \- 1) represent the lines to be scrolled out). \f(CW$saved\fR is the total
557 number of lines that will be in the scrollback buffer.

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

572 .el .IP "on_add_lines \f(CW$term\fR, \f(CW$string\fR" 4
573 .IX Item "on_add_lines $term, $string"
574 Called whenever text is about to be output, with the text as argument. You
575 can filter/change and output the text yourself by returning a true value
576 and calling \f(CW\*(C`$term\->scr_add_lines\*(C'\fR yourself. Please note that this
577 might be very slow, however, as your hook is called for \fBall\fR text being
578 output.

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