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

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 {

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 tty is in \s-1ICANON\s0 state." 4
281 .IX Item "- the tty is in ICANON state."
282 .PD 0

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

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

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

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

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

563 Called whenever the \fB\s-1ESC\s0 ] 777 ; string \s-1ST\s0\fR command sequence (\s-1OSC\s0 =
564 operating system command) is processed. Cursor position and other state
565 information is up-to-date when this happens. For interoperability, the
566 string should start with the extension name and a colon, to distinguish
567 it from commands for other extensions, and this might be enforced in the
568 future.

570 Be careful not ever to trust (in a security sense) the data you receive,
571 as its source can not easily be controleld (e\-mail content, messages from

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

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