26PREPACKAGED EXTENSIONS
27 This section describes the extensions delivered with this release. You
28 can find them in /opt/rxvt/lib/urxvt/perl/.
29
30 You can activate them like this:
31
32 rxvt -pe <extensionname>
33
34 Or by adding them to the resource for extensions loaded by default:
35
36 URxvt.perl-ext-common: default,automove-background,selection-autotransform
37
38 selection (enabled by default)
39 (More) intelligent selection. This extension tries to be more
40 intelligent when the user extends selections (double-click and
41 further clicks). Right now, it tries to select words, urls and
42 complete shell-quoted arguments, which is very convenient, too, if
43 your ls supports "--quoting-style=shell".
44
45 A double-click usually selects the word under the cursor, further
46 clicks will enlarge the selection.
47
48 The selection works by trying to match a number of regexes and
49 displaying them in increasing order of length. You can add your own
50 regexes by specifying resources of the form:
51
52 URxvt.selection.pattern-0: perl-regex
53 URxvt.selection.pattern-1: perl-regex
54 ...
55
56 The index number (0, 1...) must not have any holes, and each regex
57 must contain at least one pair of capturing parentheses, which will
58 be used for the match. For example, the followign adds a regex that
59 matches everything between two vertical bars:
60
61 URxvt.selection.pattern-0: \\|([^|]+)\\|
62
63 You can look at the source of the selection extension to see more
64 interesting uses, such as parsing a line from beginning to end.
65
66 This extension also offers following bindable keyboard commands:
67
68 rot13
69 Rot-13 the selection when activated. Used via keyboard trigger:
70
71 URxvt.keysym.C-M-r: perl:selection:rot13
72
73 option-popup (enabled by default)
74 Binds a popup menu to Ctrl-Button2 that lets you toggle (some)
75 options at runtime.
76
77 selection-popup (enabled by default)
78 Binds a popup menu to Ctrl-Button3 that lets you convert the
79 selection text into various other formats/action (such as uri
80 unescaping, perl evaluation, web-browser starting etc.), depending
81 on content.
82
83 Other extensions can extend this popup menu by pushing a code
84 reference onto "@{ $term-"{selection_popup_hook} }>, that is called
85 whenever the popup is displayed.
86
87 It's sole argument is the popup menu, which can be modified. The
88 selection is in $_, which can be used to decide wether to add
89 something or not. It should either return nothing or a string and a
90 code reference. The string will be used as button text and the code
91 reference will be called when the button gets activated and should
92 transform $_.
93
94 The following will add an entry "a to b" that transforms all "a"s in
95 the selection to "b"s, but only if the selection currently contains
96 any "a"s:
97
98 push @{ $self->{term}{selection_popup_hook} }, sub {
99 /a/ ? ("a to be" => sub { s/a/b/g }
100 : ()
101 };
102
103 searchable-scrollback<hotkey> (enabled by default)
104 Adds regex search functionality to the scrollback buffer, triggered
105 by a hotkey (default: "M-s"). While in search mode, normal terminal
106 input/output is suspended and a regex is displayed at the bottom of
107 the screen.
108
109 Inputting characters appends them to the regex and continues
110 incremental search. "BackSpace" removes a character from the regex,
111 "Up" and "Down" search upwards/downwards in the scrollback buffer,
112 "End" jumps to the bottom. "Escape" leaves search mode and returns
113 to the point where search was started, while "Enter" or "Return"
114 stay at the current position and additionally stores the first match
115 in the current line into the primary selection.
116
117 readline (enabled by default)
118 A support package that tries to make editing with readline easier.
119 At the moment, it reacts to clicking with the left mouse button by
120 trying to move the text cursor to this position. It does so by
121 generating as many cursor-left or cursor-right keypresses as
122 required (the this only works for programs that correctly support
123 wide characters).
124
125 To avoid too many false positives, this is only done when:
126
127 - the tty is in ICANON state.
128 - the text cursor is visible.
129 - the primary screen is currently being displayed.
130 - the mouse is on the same (multi-row-) line as the text cursor.
131
132 The normal selection mechanism isn't disabled, so quick successive
133 clicks might interfere with selection creation in harmless ways.
134
135 selection-autotransform
136 This selection allows you to do automatic transforms on a selection
137 whenever a selection is made.
138
139 It works by specifying perl snippets (most useful is a single "s///"
140 operator) that modify $_ as resources:
141
142 URxvt.selection-autotransform.0: transform
143 URxvt.selection-autotransform.1: transform
144 ...
145
146 For example, the following will transform selections of the form
147 "filename:number", often seen in compiler messages, into "vi
148 +$filename $word":
149
150 URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/
151
152 And this example matches the same,but replaces it with vi-commands
153 you can paste directly into your (vi :) editor:
154
155 URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/
156
157 Of course, this can be modified to suit your needs and your editor
158 :)
159
160 To expand the example above to typical perl error messages ("XXX at
161 FILENAME line YYY."), you need a slightly more elaborate solution:
162
163 URxvt.selection.pattern-0: ( at .*? line \\d+[,.])
164 URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/
165
166 The first line tells the selection code to treat the unchanging part
167 of every error message as a selection pattern, and the second line
168 transforms the message into vi commands to load the file.
169
170 tabbed
171 This transforms the terminal into a tabbar with additional
172 terminals, that is, it implements what is commonly refered to as
173 "tabbed terminal". The topmost line displays a "[NEW]" button,
174 which, when clicked, will add a new tab, followed by one button per
175 tab.
176
177 Clicking a button will activate that tab. Pressing Shift-Left and
178 Shift-Right will switch to the tab left or right of the current one,
179 while Shift-Down creates a new tab.
180
181 mark-urls
182 Uses per-line display filtering ("on_line_update") to underline urls
183 and make them clickable. When middle-clicked, the program specified
184 in the resource "urlLauncher" (default "x-www-browser") will be
185 started with the URL as first argument.
186
187 automove-background
188 This is basically a one-line extension that dynamically changes the
189 background pixmap offset to the window position, in effect creating
190 the same effect as pseudo transparency with a custom pixmap. No
191 scaling is supported in this mode. Exmaple:
192
193 rxvt -pixmap background.xpm -pe automove-background
194
195 block-graphics-to-ascii
196 A not very useful example of filtering all text output to the
197 terminal, by replacing all line-drawing characters (U+2500 ..
198 U+259F) by a similar-looking ascii character.
199
200 digital-clock
201 Displays a digital clock using the built-in overlay.
202
203 example-refresh-hooks
204 Displays a very simple digital clock in the upper right corner of
205 the window. Illustrates overwriting the refresh callbacks to create
206 your own overlays or changes.
207
208 selection-pastebin
209 This is a little rarely useful extension that Uploads the selection
210 as textfile to a remote site (or does other things). (The
211 implementation is not currently secure for use in a multiuser
212 environment as it writes to /tmp directly.).
213
214 It listens to the "selection-pastebin:remote-pastebin" keyboard
215 command, i.e.
216
217 URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
218
219 Pressing this combination runs a command with "%" replaced by the
220 name of the textfile. This command can be set via a resource:
221
222 URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
223
224 And the default is likely not useful to anybody but the few people
225 around here :)
226
227 The name of the textfile is the hex encoded md5 sum of the
228 selection, so the same content should lead to the same filename.
229
230 After a successful upload the selection will be replaced by the text
231 given in the "selection-pastebin-url" resource (again, the % is the
232 placeholder for the filename):
233
234 URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/%

37 248
249 Argument names also often indicate the type of a parameter. Here are
250 some hints on what they mean:
251
252 $text
253 Rxvt-unicodes special way of encoding text, where one "unicode"
254 character always represents one screen cell. See ROW_t for a
255 discussion of this format.
256
257 $string
258 A perl text string, with an emphasis on *text*. It can store all
259 unicode characters and is to be distinguished with text encoded in a
260 specific encoding (often locale-specific) and binary data.
261
262 $octets
263 Either binary data or - more common - a text string encoded in a
264 locale-specific way.
265
266 Extension Objects
267 Very perl extension is a perl class. A separate perl object is created
268 for each terminal and each extension and passed as the first parameter
269 to hooks. So extensions can use their $self object without having to
270 think about other extensions, with the exception of methods and members
271 that begin with an underscore character "_": these are reserved for
272 internal use.
273
274 Although it isn't a "urxvt::term" object, you can call all methods of
275 the "urxvt::term" class on this object.
276
277 It has the following methods and data members:
278
279 $urxvt_term = $self->{term}
280 Returns the "urxvt::term" object associated with this instance of
281 the extension. This member *must not* be changed in any way.
282
283 $self->enable ($hook_name => $cb, [$hook_name => $cb..])
284 Dynamically enable the given hooks (named without the "on_" prefix)
285 for this extension, replacing any previous hook. This is useful when
286 you want to overwrite time-critical hooks only temporarily.
287
288 $self->disable ($hook_name[, $hook_name..])
289 Dynamically disable the given hooks.

50 Called after a new terminal object has been initialized, but before 305 Called after a new terminal object has been initialized, but before
51 windows are created or the command gets run. 306 windows are created or the command gets run. Most methods are unsafe
307 to call or deliver senseless data, as terminal size and other
308 characteristics have not yet been determined. You can safely query
309 and change resources and options, though. For many purposes the
310 "on_start" hook is a better place.
311
312 on_start $term
313 Called at the very end of initialisation of a new terminal, just
314 before trying to map (display) the toplevel and returning to the
315 mainloop.
316
317 on_destroy $term
318 Called whenever something tries to destroy terminal, before doing
319 anything yet. If this hook returns true, then destruction is
320 skipped, but this is rarely a good idea.
52 321
53 on_reset $term 322 on_reset $term

60 before returning to the mainloop. 329
330 on_child_exit $term, $status
331 Called just after the child process has exited. $status is the
332 status from "waitpid".
61 333
62 on_sel_make $term, $eventtime 334 on_sel_make $term, $eventtime

78 350
79 on_focus_in $term 351 on_sel_extend $term
80 Called whenever the window gets the keyboard focus, before urxvt 352 Called whenever the user tries to extend the selection (e.g. with a
81 does focus in processing. 353 double click) and is either supposed to return false (normal
354 operation), or should extend the selection itelf and return true to
355 suppress the built-in processing. This can happen multiple times, as
356 long as the callback returns true, it will be called on every
357 further click by the user and is supposed to enlarge the selection
358 more and more, if possible.
82 359
83 on_focus_out $term 360 See the selection example extension.
84 Called wheneever the window loses keyboard focus, before urxvt does
85 focus out processing.
86 361
87 on_view_change $term, $offset 362 on_view_change $term, $offset
88 Called whenever the view offset changes, i..e the user or program 363 Called whenever the view offset changes, i..e the user or program
89 scrolls. Offset 0 means display the normal terminal, positive values 364 scrolls. Offset 0 means display the normal terminal, positive values

98 - 1, $nrow - 1) represent the lines to be scrolled out). $saved is 373 - 1, $nrow - 1) represent the lines to be scrolled out). $saved is
99 the total number of lines that will be in the scrollback buffer. 374 the total number of lines that will be in the scrollback buffer.
100 375
101 on_tty_activity $term *NYI* 376 on_osc_seq $term, $string
102 Called whenever the program(s) running in the urxvt window send 377 Called whenever the ESC ] 777 ; string ST command sequence (OSC =
103 output. 378 operating system command) is processed. Cursor position and other
379 state information is up-to-date when this happens. For
380 interoperability, the string should start with the extension name
381 and a colon, to distinguish it from commands for other extensions,
382 and this might be enforced in the future.
383
384 Be careful not ever to trust (in a security sense) the data you
385 receive, as its source can not easily be controleld (e-mail content,
386 messages from other users on the same system etc.).
387
388 on_add_lines $term, $string
389 Called whenever text is about to be output, with the text as
390 argument. You can filter/change and output the text yourself by
391 returning a true value and calling "$term->scr_add_lines" yourself.
392 Please note that this might be very slow, however, as your hook is
393 called for all text being output.
394
395 on_tt_write $term, $octets
396 Called whenever some data is written to the tty/pty and can be used
397 to suppress or filter tty input.
398
399 on_line_update $term, $row
400 Called whenever a line was updated or changed. Can be used to filter
401 screen output (e.g. underline urls or other useless stuff). Only
402 lines that are being shown will be filtered, and, due to performance
403 reasons, not always immediately.
404
405 The row number is always the topmost row of the line if the line
406 spans multiple rows.
407
408 Please note that, if you change the line, then the hook might get
409 called later with the already-modified line (e.g. if unrelated parts
410 change), so you cannot just toggle rendition bits, but only set
411 them.
104 412
105 on_refresh_begin $term 413 on_refresh_begin $term
106 Called just before the screen gets redrawn. Can be used for overlay 414 Called just before the screen gets redrawn. Can be used for overlay
107 or similar effects by modify terminal contents in refresh_begin, and 415 or similar effects by modify terminal contents in refresh_begin, and
108 restoring them in refresh_end. The built-in overlay and selection 416 restoring them in refresh_end. The built-in overlay and selection
114 on_keyboard_command $term, $string 422 on_keyboard_command $term, $string
115 Called whenever the user presses a key combination that has a 423 Called whenever the user presses a key combination that has a
116 "perl:string" action bound to it (see description of the keysym 424 "perl:string" action bound to it (see description of the keysym
117 resource in the rxvt(1) manpage). 425 resource in the rxvt(1) manpage).
118 426
427 on_x_event $term, $event
428 Called on every X event received on the vt window (and possibly
429 other windows). Should only be used as a last resort. Most event
430 structure members are not passed.
431
432 on_focus_in $term
433 Called whenever the window gets the keyboard focus, before
434 rxvt-unicode does focus in processing.
435
436 on_focus_out $term
437 Called wheneever the window loses keyboard focus, before
438 rxvt-unicode does focus out processing.
439
440 on_configure_notify $term, $event
441 on_property_notify $term, $event
442 on_key_press $term, $event, $keysym, $octets
443 on_key_release $term, $event, $keysym

445 on_button_release $term, $event
446 on_motion_notify $term, $event
447 on_map_notify $term, $event
448 on_unmap_notify $term, $event
449 Called whenever the corresponding X event is received for the
450 terminal If the hook returns true, then the even will be ignored by
451 rxvt-unicode.
452
453 The event is a hash with most values as named by Xlib (see the
454 XEvent manpage), with the additional members "row" and "col", which
455 are the (real, not screen-based) row and column under the mouse
456 cursor.
457
458 "on_key_press" additionally receives the string rxvt-unicode would
459 output, if any, in locale-specific encoding.
460
461 subwindow.
462
463 on_client_message $term, $event
464 on_wm_protocols $term, $event
465 on_wm_delete_window $term, $event
466 Called when various types of ClientMessage events are received (all
467 with format=32, WM_PROTOCOLS or WM_PROTOCOLS:WM_DELETE_WINDOW).
468
469 Variables in the "urxvt" Package
470 $urxvt::LIBDIR
471 The rxvt-unicode library directory, where, among other things, the
472 perl modules and scripts are stored.
473
474 $urxvt::RESCLASS, $urxvt::RESCLASS
475 The resource class and name rxvt-unicode uses to look up X
476 resources.
477
478 $urxvt::RXVTNAME
479 The basename of the installed binaries, usually "urxvt".
480
481 $urxvt::TERM
482 The current terminal. This variable stores the current "urxvt::term"
483 object, whenever a callback/hook is executing.
484
485 @urxvt::TERM_INIT
486 All coderefs in this array will be called as methods of the next
487 newly created "urxvt::term" object (during the "on_init" phase). The
488 array gets cleared before the codereferences that were in it are
489 being executed, so coderefs can push themselves onto it again if
490 they so desire.
491
492 This complements to the perl-eval commandline option, but gets
493 executed first.
494
495 @urxvt::TERM_EXT
496 Works similar to @TERM_INIT, but contains perl package/class names,
497 which get registered as normal extensions after calling the hooks in
498 @TERM_INIT but before other extensions. Gets cleared just like
499 @TERM_INIT.

541 RENDITION
542 Rendition bitsets contain information about colour, font, font styles
543 and similar information for each screen cell.
544
545 The following "macros" deal with changes in rendition sets. You should
546 never just create a bitset, you should always modify an existing one, as
547 they contain important information required for correct operation of
548 rxvt-unicode.
549
550 $rend = urxvt::DEFAULT_RSTYLE
551 Returns the default rendition, as used when the terminal is starting
552 up or being reset. Useful as a base to start when creating
553 renditions.
554
555 $rend = urxvt::OVERLAY_RSTYLE
556 Return the rendition mask used for overlays by default.
557
558 $rendbit = urxvt::RS_Bold, RS_Italic, RS_Blink, RS_RVid, RS_Uline
559 Return the bit that enabled bold, italic, blink, reverse-video and
560 underline, respectively. To enable such a style, just logically OR
561 it into the bitset.
562
563 $foreground = urxvt::GET_BASEFG $rend
564 $background = urxvt::GET_BASEBG $rend
565 Return the foreground/background colour index, respectively.
566
567 $rend = urxvt::SET_FGCOLOR $rend, $new_colour
568 $rend = urxvt::SET_BGCOLOR $rend, $new_colour
569 Replace the foreground/background colour in the rendition mask with
570 the specified one.
571
572 $value = urxvt::GET_CUSTOM $rend
573 Return the "custom" value: Every rendition has 5 bits for use by
574 extensions. They can be set and changed as you like and are
575 initially zero.
576
577 $rend = urxvt::SET_CUSTOM $rend, $new_value
578 Change the custom value.
579
580 The "urxvt::anyevent" Class
581 The sole purpose of this class is to deliver an interface to the
582 "AnyEvent" module - any module using it will work inside urxvt without
583 further programming. The only exception is that you cannot wait on
584 condition variables, but non-blocking condvar use is ok. What this means
585 is that you cannot use blocking APIs, but the non-blocking variant
586 should work.
587
136 The "urxvt::term" Class 588 The "urxvt::term" Class
589 $term = new urxvt::term $envhashref, $rxvtname, [arg...]
590 Creates a new terminal, very similar as if you had started it with
591 system "$rxvtname, arg...". $envhashref must be a reference to a
592 %ENV-like hash which defines the environment of the new terminal.
593
594 Croaks (and probably outputs an error message) if the new instance
595 couldn't be created. Returns "undef" if the new instance didn't
596 initialise perl, and the terminal object otherwise. The "init" and
597 "start" hooks will be called during this call.
598
599 $term->destroy
600 Destroy the terminal object (close the window, free resources etc.).
601 Please note that rxvt will not exit as long as any event watchers
602 (timers, io watchers) are still active.
603
604 $term->exec_async ($cmd[, @args])
605 Works like the combination of the "fork"/"exec" builtins, which
606 executes ("starts") programs in the background. This function takes
607 care of setting the user environment before exec'ing the command
608 (e.g. "PATH") and should be preferred over explicit calls to "exec"
609 or "system".
610
611 Returns the pid of the subprocess or "undef" on error.
612
613 $isset = $term->option ($optval[, $set])
614 Returns true if the option specified by $optval is enabled, and
615 optionally change it. All option values are stored by name in the
616 hash %urxvt::OPTION. Options not enabled in this binary are not in
617 the hash.

664 $value = $term->x_resource ($pattern)
665 Returns the X-Resource for the given pattern, excluding the program
666 or class name, i.e. "$term->x_resource ("boldFont")" should return
667 the same value as used by this instance of rxvt-unicode. Returns
668 "undef" if no resource with that pattern exists.
669
670 This method should only be called during the "on_start" hook, as
671 there is only one resource database per display, and later
672 invocations might return the wrong resources.
673
674 $success = $term->parse_keysym ($keysym_spec, $command_string)
675 Adds a keymap translation exactly as specified via a resource. See
676 the "keysym" resource in the rxvt(1) manpage.
677
678 $rend = $term->rstyle ([$new_rstyle])
679 Return and optionally change the current rendition. Text that is
680 output by the terminal application will use this style.
681
682 ($row, $col) = $term->screen_cur ([$row, $col])
683 Return the current coordinates of the text cursor position and
684 optionally set it (which is usually bad as applications don't expect
685 that).
170 686
171 ($row, $col) = $term->selection_mark ([$row, $col]) 687 ($row, $col) = $term->selection_mark ([$row, $col])
172 ($row, $col) = $term->selection_beg ([$row, $col]) 688 ($row, $col) = $term->selection_beg ([$row, $col])
173 ($row, $col) = $term->selection_end ([$row, $col]) 689 ($row, $col) = $term->selection_end ([$row, $col])
174 Return the current values of the selection mark, begin or end 690 Return the current values of the selection mark, begin or end
175 positions, and optionally set them to new values. 691 positions, and optionally set them to new values.
176 692
693 $term->selection_make ($eventtime[, $rectangular])
694 Tries to make a selection as set by "selection_beg" and
695 "selection_end". If $rectangular is true (default: false), a
696 rectangular selection will be made. This is the prefered function to
697 make a selection.
698
177 $success = $term->selection_grab ($eventtime) 699 $success = $term->selection_grab ($eventtime)
178 Try to request the primary selection from the server (for example, 700 Try to request the primary selection text from the server (for
179 as set by the next method). 701 example, as set by the next method). No visual feedback will be
702 given. This function is mostly useful from within "on_sel_grab"
703 hooks.
180 704
181 $oldtext = $term->selection ([$newtext]) 705 $oldtext = $term->selection ([$newtext])
182 Return the current selection text and optionally replace it by 706 Return the current selection text and optionally replace it by
183 $newtext. 707 $newtext.
184 708
185 $term->scr_overlay ($x, $y, $text) 709 $term->overlay_simple ($x, $y, $text)
186 Create a simple multi-line overlay box. See the next method for 710 Create a simple multi-line overlay box. See the next method for
187 details. 711 details.
188 712
189 $term->scr_overlay_new ($x, $y, $width, $height) 713 $term->overlay ($x, $y, $width, $height[, $rstyle[, $border]])
190 Create a new (empty) overlay at the given position with the given 714 Create a new (empty) overlay at the given position with the given
191 width/height. A border will be put around the box. If either $x or 715 width/height. $rstyle defines the initial rendition style (default:
716 "OVERLAY_RSTYLE").
717
718 If $border is 2 (default), then a decorative border will be put
719 around the box.
720
192 $y is negative, then this is counted from the right/bottom side, 721 If either $x or $y is negative, then this is counted from the
193 respectively. 722 right/bottom side, respectively.
194 723
195 $term->scr_overlay_off 724 This method returns an urxvt::overlay object. The overlay will be
196 Switch the overlay off again. 725 visible as long as the perl object is referenced.
197 726
198 $term->scr_overlay_set_char ($x, $y, $char, $rend = OVERLAY_RSTYLE) 727 The methods currently supported on "urxvt::overlay" objects are:
199 Put a single character (specified numerically) at the given overlay
200 position.
201 728
202 $term->scr_overlay_set ($x, $y, $text) 729 $overlay->set ($x, $y, $text, $rend)
203 Write a string at the given position into the overlay. 730 Similar to "$term->ROW_t" and "$term->ROW_r" in that it puts
731 text in rxvt-unicode's special encoding and an array of
732 rendition values at a specific position inside the overlay.
204 733
734 $overlay->hide
735 If visible, hide the overlay, but do not destroy it.
736
737 $overlay->show
738 If hidden, display the overlay again.
739
740 $popup = $term->popup ($event)
741 Creates a new "urxvt::popup" object that implements a popup menu.
742 The $event *must* be the event causing the menu to pop up (a button
743 event, currently).
744
205 $cellwidth = $term->strwidth $string 745 $cellwidth = $term->strwidth ($string)
206 Returns the number of screen-cells this string would need. Correctly 746 Returns the number of screen-cells this string would need. Correctly
207 accounts for wide and combining characters. 747 accounts for wide and combining characters.
208 748
209 $octets = $term->locale_encode $string 749 $octets = $term->locale_encode ($string)
210 Convert the given text string into the corresponding locale 750 Convert the given text string into the corresponding locale
211 encoding. 751 encoding.
212 752
213 $string = $term->locale_decode $octets 753 $string = $term->locale_decode ($octets)
214 Convert the given locale-encoded octets into a perl string. 754 Convert the given locale-encoded octets into a perl string.
755
756 $term->scr_xor_span ($beg_row, $beg_col, $end_row, $end_col[, $rstyle])
757 XORs the rendition values in the given span with the provided value
758 (default: "RS_RVid"), which *MUST NOT* contain font styles. Useful
759 in refresh hooks to provide effects similar to the selection.
760
761 $term->scr_xor_rect ($beg_row, $beg_col, $end_row, $end_col[, $rstyle1[,
762 $rstyle2]])
763 Similar to "scr_xor_span", but xors a rectangle instead. Trailing
764 whitespace will additionally be xored with the $rstyle2, which
765 defaults to "RS_RVid | RS_Uline", which removes reverse video again
766 and underlines it instead. Both styles *MUST NOT* contain font
767 styles.
768
769 $term->scr_bell
770 Ring the bell!
771
772 $term->scr_add_lines ($string)
773 Write the given text string to the screen, as if output by the
774 application running inside the terminal. It may not contain command
775 sequences (escape codes), but is free to use line feeds, carriage
776 returns and tabs. The string is a normal text string, not in
777 locale-dependent encoding.
778
779 Normally its not a good idea to use this function, as programs might
780 be confused by changes in cursor position or scrolling. Its useful
781 inside a "on_add_lines" hook, though.
782
783 $term->scr_change_screen ($screen)
784 Switch to given screen - 0 primary, 1 secondary.
785
786 $term->cmd_parse ($octets)
787 Similar to "scr_add_lines", but the argument must be in the
788 locale-specific encoding of the terminal and can contain command
789 sequences (escape codes) that will be interpreted.
215 790
216 $term->tt_write ($octets) 791 $term->tt_write ($octets)
217 Write the octets given in $data to the tty (i.e. as program input). 792 Write the octets given in $data to the tty (i.e. as program input).
218 To pass characters instead of octets, you should convetr you strings 793 To pass characters instead of octets, you should convert your
219 first to the locale-specific encoding using "$term->locale_encode". 794 strings first to the locale-specific encoding using
795 "$term->locale_encode".
796
797 $old_events = $term->pty_ev_events ([$new_events])
798 Replaces the event mask of the pty watcher by the given event mask.
799 Can be used to suppress input and output handling to the pty/tty.
800 See the description of "urxvt::timer->events". Make sure to always
801 restore the previous value.
802
803 $fd = $term->pty_fd
804 Returns the master file descriptor for the pty in use, or -1 if no
805 pty is used.
806
807 $windowid = $term->parent
808 Return the window id of the toplevel window.
809
810 $windowid = $term->vt
811 Return the window id of the terminal window.
812
813 $term->vt_emask_add ($x_event_mask)
814 Adds the specified events to the vt event mask. Useful e.g. when you
815 want to receive pointer events all the times:
816
817 $term->vt_emask_add (urxvt::PointerMotionMask);
818
819 $window_width = $term->width
820 $window_height = $term->height
821 $font_width = $term->fwidth
822 $font_height = $term->fheight
823 $font_ascent = $term->fbase
824 $terminal_rows = $term->nrow
825 $terminal_columns = $term->ncol
826 $has_focus = $term->focus
827 $is_mapped = $term->mapped
828 $max_scrollback = $term->saveLines
829 $nrow_plus_saveLines = $term->total_rows
830 $topmost_scrollback_row = $term->top_row
831 Return various integers describing terminal characteristics.
832
833 $x_display = $term->display_id
834 Return the DISPLAY used by rxvt-unicode.
835
836 $lc_ctype = $term->locale
837 Returns the LC_CTYPE category string used by this rxvt-unicode.
838
839 $env = $term->env
840 Returns a copy of the environment in effect for the terminal as a
841 hashref similar to "\%ENV".
842
843 $modifiermask = $term->ModLevel3Mask
844 $modifiermask = $term->ModMetaMask
845 $modifiermask = $term->ModNumLockMask
846 Return the modifier masks corresponding to the "ISO Level 3 Shift"
847 (often AltGr), the meta key (often Alt) and the num lock key, if
848 applicable.
849
850 $screen = $term->current_screen
851 Returns the currently displayed screen (0 primary, 1 secondary).
852
853 $cursor_is_hidden = $term->hidden_cursor
854 Returns wether the cursor is currently hidden or not.
855
856 $view_start = $term->view_start ([$newvalue])
857 Returns the row number of the topmost displayed line. Maximum value
858 is 0, which displays the normal terminal contents. Lower values
859 scroll this many lines into the scrollback buffer.
860
861 $term->want_refresh
862 Requests a screen refresh. At the next opportunity, rxvt-unicode
863 will compare the on-screen display with its stored representation.
864 If they differ, it redraws the differences.
865
866 Used after changing terminal contents to display them.
867
868 $text = $term->ROW_t ($row_number[, $new_text[, $start_col]])
869 Returns the text of the entire row with number $row_number. Row 0 is
870 the topmost terminal line, row "$term->$ncol-1" is the bottommost
871 terminal line. The scrollback buffer starts at line -1 and extends
872 to line "-$term->nsaved". Nothing will be returned if a nonexistent
873 line is requested.
874
875 If $new_text is specified, it will replace characters in the current
876 line, starting at column $start_col (default 0), which is useful to
877 replace only parts of a line. The font index in the rendition will
878 automatically be updated.
879
880 $text is in a special encoding: tabs and wide characters that use
881 more than one cell when displayed are padded with $urxvt::NOCHAR
882 (chr 65535) characters. Characters with combining characters and
883 other characters that do not fit into the normal tetx encoding will
884 be replaced with characters in the private use area.
885
886 You have to obey this encoding when changing text. The advantage is
887 that "substr" and similar functions work on screen cells and not on
888 characters.
889
890 The methods "$term->special_encode" and "$term->special_decode" can
891 be used to convert normal strings into this encoding and vice versa.
892
893 $rend = $term->ROW_r ($row_number[, $new_rend[, $start_col]])
894 Like "$term->ROW_t", but returns an arrayref with rendition bitsets.
895 Rendition bitsets contain information about colour, font, font
896 styles and similar information. See also "$term->ROW_t".
897
898 When setting rendition, the font mask will be ignored.
899
900 See the section on RENDITION, above.
901
902 $length = $term->ROW_l ($row_number[, $new_length])
903 Returns the number of screen cells that are in use ("the line
904 length"). Unlike the urxvt core, this returns "$term->ncol" if the
905 line is joined with the following one.
906
907 $bool = $term->is_longer ($row_number)
908 Returns true if the row is part of a multiple-row logical "line"
909 (i.e. joined with the following row), which means all characters are
910 in use and it is continued on the next row (and possibly a
911 continuation of the previous row(s)).
912
913 $line = $term->line ($row_number)
914 Create and return a new "urxvt::line" object that stores information
915 about the logical line that row $row_number is part of. It supports
916 the following methods:
917
918 $text = $line->t ([$new_text])
919 Returns or replaces the full text of the line, similar to
920 "ROW_t"
921
922 $rend = $line->r ([$new_rend])
923 Returns or replaces the full rendition array of the line,
924 similar to "ROW_r"
925
926 $length = $line->l
927 Returns the length of the line in cells, similar to "ROW_l".
928
929 $rownum = $line->beg
930 $rownum = $line->end
931 Return the row number of the first/last row of the line,
932 respectively.
933
934 $offset = $line->offset_of ($row, $col)
935 Returns the character offset of the given row|col pair within
936 the logical line. Works for rows outside the line, too, and
937 returns corresponding offsets outside the string.
938
939 ($row, $col) = $line->coord_of ($offset)
940 Translates a string offset into terminal coordinates again.
941
942 $text = $term->special_encode $string
943 Converts a perl string into the special encoding used by
944 rxvt-unicode, where one character corresponds to one screen cell.
945 See "$term->ROW_t" for details.
946
947 $string = $term->special_decode $text
948 Converts rxvt-unicodes text reprsentation into a perl string. See
949 "$term->ROW_t" for details.
950
951 $success = $term->grab_button ($button, $modifiermask)
952 Registers a synchronous button grab. See the XGrabButton manpage.
953
954 $success = $term->grab ($eventtime[, $sync])
955 Calls XGrabPointer and XGrabKeyboard in asynchronous (default) or
956 synchronous ($sync is true). Also remembers the grab timestampe.
957
958 $term->allow_events_async
