18DESCRIPTION 16DESCRIPTION
19 On startup, rxvt will scan /opt/rxvt/lib/urxvt/perl-ext/ for files and 17 Everytime a terminal object gets created, extension scripts specified
20 will load them. Everytime a terminal object gets created, the directory 18 via the "perl" resource are loaded and associated with it.
21 specified by the "perl-lib" resource will be additionally scanned. 19
20 Scripts are compiled in a 'use strict' and 'use utf8' environment, and
21 thus must be encoded as UTF-8.

23 Each script will only ever be loaded once, even in rxvtd, where scripts 23 Each script will only ever be loaded once, even in rxvtd, where scripts
24 will be shared for all terminals. 24 will be shared (but not enabled) for all terminals.
25 25
26 Hooks in scripts specified by "perl-lib" will only be called for the 26PREPACKAGED EXTENSIONS
27 terminals created with that specific option value. 27 This section describes the extensions delivered with this release. You
28 can find them in /opt/rxvt/lib/urxvt/perl/.
28 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 selection-autotransform
118 This selection allows you to do automatic transforms on a selection
119 whenever a selection is made.
120
121 It works by specifying perl snippets (most useful is a single "s///"
122 operator) that modify $_ as resources:
123
124 URxvt.selection-autotransform.0: transform
125 URxvt.selection-autotransform.1: transform
126 ...
127
128 For example, the following will transform selections of the form
129 "filename:number", often seen in compiler messages, into "vi
130 +$filename $word":
131
132 URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/
133
134 And this example matches the same,but replaces it with vi-commands
135 you can paste directly into your (vi :) editor:
136
137 URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/
138
139 Of course, this can be modified to suit your needs and your editor
140 :)
141
142 To expand the example above to typical perl error messages ("XXX at
143 FILENAME line YYY."), you need a slightly more elaborate solution:
144
145 URxvt.selection.pattern-0: ( at .*? line \\d+[,.])
146 URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/
147
148 The first line tells the selection code to treat the unchanging part
149 of every error message as a selection pattern, and the second line
150 transforms the message into vi commands to load the file.
151
152 readline
153 A support package that tries to make editing with readline easier.
154 At the moment, it reacts to clicking with the left mouse button by
155 trying to move the text cursor to this position. It does so by
156 generating as many cursor-left or cursor-right keypresses as
157 required (the this only works for programs that correctly support
158 wide characters).
159
160 It only works when clicking into the same line (possibly extended
161 over multiple rows) as the text cursor and on the primary screen, to
162 reduce the risk of misinterpreting. The normal selection isn't
163 disabled, so quick successive clicks might interfere with selection
164 creation in harmless ways.
165
166 tabbed
167 This transforms the terminal into a tabbar with additional
168 terminals, that is, it implements what is commonly refered to as
169 "tabbed terminal". The topmost line displays a "[NEW]" button,
170 which, when clicked, will add a new tab, followed by one button per
171 tab.
172
173 Clicking a button will activate that tab. Pressing Shift-Left and
174 Shift-Right will switch to the tab left or right of the current one,
175 while Shift-Down creates a new tab.
176
177 mark-urls
178 Uses per-line display filtering ("on_line_update") to underline urls
179 and make them clickable. When middle-clicked, the program specified
180 in the resource "urlLauncher" (default "x-www-browser") will be
181 started with the URL as first argument.
182
183 automove-background
184 This is basically a one-line extension that dynamically changes the
185 background pixmap offset to the window position, in effect creating
186 the same effect as pseudo transparency with a custom pixmap. No
187 scaling is supported in this mode. Exmaple:
188
189 rxvt -pixmap background.xpm -pe automove-background
190
191 block-graphics-to-ascii
192 A not very useful example of filtering all text output to the
193 terminal, by replacing all line-drawing characters (U+2500 ..
194 U+259F) by a similar-looking ascii character.
195
196 digital-clock
197 Displays a digital clock using the built-in overlay.
198
199 example-refresh-hooks
200 Displays a very simple digital clock in the upper right corner of
201 the window. Illustrates overwriting the refresh callbacks to create
202 your own overlays or changes.
203
204 selection-pastebin
205 This is a little rarely useful extension that Uploads the selection
206 as textfile to a remote site (or does other things). (The
207 implementation is not currently secure for use in a multiuser
208 environment as it writes to /tmp directly.).
209
210 It listens to the "selection-pastebin:remote-pastebin" keyboard
211 command, i.e.
212
213 URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
214
215 Pressing this combination runs a command with "%" replaced by the
216 name of the textfile. This command can be set via a resource:
217
218 URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
219
220 And the default is likely not useful to anybody but the few people
221 around here :)
222
223 The name of the textfile is the hex encoded md5 sum of the
224 selection, so the same content should lead to the same filename.
225
226 After a successful upload the selection will be replaced by the text
227 given in the "selection-pastebin-url" resource (again, the % is the
228 placeholder for the filename):
229
230 URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/%

40 244
245 Argument names also often indicate the type of a parameter. Here are
246 some hints on what they mean:
247
248 $text
249 Rxvt-unicodes special way of encoding text, where one "unicode"
250 character always represents one screen cell. See ROW_t for a
251 discussion of this format.
252
253 $string
254 A perl text string, with an emphasis on *text*. It can store all
255 unicode characters and is to be distinguished with text encoded in a
256 specific encoding (often locale-specific) and binary data.
257
258 $octets
259 Either binary data or - more common - a text string encoded in a
260 locale-specific way.
261
262 Extension Objects
263 Very perl extension is a perl class. A separate perl object is created
264 for each terminal and each extension and passed as the first parameter
265 to hooks. So extensions can use their $self object without having to
266 think about other extensions, with the exception of methods and members
267 that begin with an underscore character "_": these are reserved for
268 internal use.
269
270 Although it isn't a "urxvt::term" object, you can call all methods of
271 the "urxvt::term" class on this object.
272
273 It has the following methods and data members:
274
275 $urxvt_term = $self->{term}
276 Returns the "urxvt::term" object associated with this instance of
277 the extension. This member *must not* be changed in any way.
278
279 $self->enable ($hook_name => $cb, [$hook_name => $cb..])
280 Dynamically enable the given hooks (named without the "on_" prefix)
281 for this extension, replacing any previous hook. This is useful when
282 you want to overwrite time-critical hooks only temporarily.
283
284 $self->disable ($hook_name[, $hook_name..])
285 Dynamically disable the given hooks.
286

52 on_init $term 300 on_init $term
53 Called after a new terminal object has been initialized, but before 301 Called after a new terminal object has been initialized, but before
54 windows are created or the command gets run. 302 windows are created or the command gets run. Most methods are unsafe
303 to call or deliver senseless data, as terminal size and other
304 characteristics have not yet been determined. You can safely query
305 and change resources and options, though. For many purposes the
306 "on_start" hook is a better place.
307
308 on_start $term
309 Called at the very end of initialisation of a new terminal, just
310 before trying to map (display) the toplevel and returning to the
311 mainloop.
312
313 on_destroy $term
314 Called whenever something tries to destroy terminal, before doing
315 anything yet. If this hook returns true, then destruction is
316 skipped, but this is rarely a good idea.
55 317
56 on_reset $term 318 on_reset $term
57 Called after the screen is "reset" for any reason, such as resizing 319 Called after the screen is "reset" for any reason, such as resizing

63 before returning to the mainloop. 325
326 on_child_exit $term, $status
327 Called just after the child process has exited. $status is the
328 status from "waitpid".
64 329
65 on_sel_make $term, $eventtime 330 on_sel_make $term, $eventtime
66 Called whenever a selection has been made by the user, but before 331 Called whenever a selection has been made by the user, but before
67 the selection text is copied, so changes to the beginning, end or 332 the selection text is copied, so changes to the beginning, end or

81 346
82 on_focus_in $term 347 on_sel_extend $term
83 Called whenever the window gets the keyboard focus, before urxvt 348 Called whenever the user tries to extend the selection (e.g. with a
84 does focus in processing. 349 double click) and is either supposed to return false (normal
350 operation), or should extend the selection itelf and return true to
351 suppress the built-in processing. This can happen multiple times, as
352 long as the callback returns true, it will be called on every
353 further click by the user and is supposed to enlarge the selection
354 more and more, if possible.
85 355
86 on_focus_out $term 356 See the selection example extension.
87 Called wheneever the window loses keyboard focus, before urxvt does
88 focus out processing.
89 357
90 on_view_change $term, $offset 358 on_view_change $term, $offset
91 Called whenever the view offset changes, i..e the user or program 359 Called whenever the view offset changes, i..e the user or program
92 scrolls. Offset 0 means display the normal terminal, positive values 360 scrolls. Offset 0 means display the normal terminal, positive values
93 show this many lines of scrollback. 361 show this many lines of scrollback.

100 It is called before lines are scrolled out (so rows 0 .. min ($lines 368 It is called before lines are scrolled out (so rows 0 .. min ($lines
101 - 1, $nrow - 1) represent the lines to be scrolled out). $saved is 369 - 1, $nrow - 1) represent the lines to be scrolled out). $saved is
102 the total number of lines that will be in the scrollback buffer. 370 the total number of lines that will be in the scrollback buffer.
103 371
104 on_tty_activity $term *NYI* 372 on_osc_seq $term, $string
105 Called whenever the program(s) running in the urxvt window send 373 Called whenever the ESC ] 777 ; string ST command sequence (OSC =
106 output. 374 operating system command) is processed. Cursor position and other
375 state information is up-to-date when this happens. For
376 interoperability, the string should start with the extension name
377 and a colon, to distinguish it from commands for other extensions,
378 and this might be enforced in the future.
379
380 Be careful not ever to trust (in a security sense) the data you
381 receive, as its source can not easily be controleld (e-mail content,
382 messages from other users on the same system etc.).
383
384 on_add_lines $term, $string
385 Called whenever text is about to be output, with the text as
386 argument. You can filter/change and output the text yourself by
387 returning a true value and calling "$term->scr_add_lines" yourself.
388 Please note that this might be very slow, however, as your hook is
389 called for all text being output.
390
391 on_tt_write $term, $octets
392 Called whenever some data is written to the tty/pty and can be used
393 to suppress or filter tty input.
394
395 on_line_update $term, $row
396 Called whenever a line was updated or changed. Can be used to filter
397 screen output (e.g. underline urls or other useless stuff). Only
398 lines that are being shown will be filtered, and, due to performance
399 reasons, not always immediately.
400
401 The row number is always the topmost row of the line if the line
402 spans multiple rows.
403
404 Please note that, if you change the line, then the hook might get
405 called later with the already-modified line (e.g. if unrelated parts
406 change), so you cannot just toggle rendition bits, but only set
407 them.
107 408
108 on_refresh_begin $term 409 on_refresh_begin $term
109 Called just before the screen gets redrawn. Can be used for overlay 410 Called just before the screen gets redrawn. Can be used for overlay
110 or similar effects by modify terminal contents in refresh_begin, and 411 or similar effects by modify terminal contents in refresh_begin, and
111 restoring them in refresh_end. The built-in overlay and selection 412 restoring them in refresh_end. The built-in overlay and selection
112 display code is run after this hook, and takes precedence. 413 display code is run after this hook, and takes precedence.
113 414
114 on_refresh_end $term 415 on_refresh_end $term
115 Called just after the screen gets redrawn. See "on_refresh_begin". 416 Called just after the screen gets redrawn. See "on_refresh_begin".
116 417
418 on_keyboard_command $term, $string
419 Called whenever the user presses a key combination that has a
420 "perl:string" action bound to it (see description of the keysym
421 resource in the rxvt(1) manpage).
422
423 on_x_event $term, $event
424 Called on every X event received on the vt window (and possibly
425 other windows). Should only be used as a last resort. Most event
426 structure members are not passed.
427
428 on_focus_in $term
429 Called whenever the window gets the keyboard focus, before
430 rxvt-unicode does focus in processing.
431
432 on_focus_out $term
433 Called wheneever the window loses keyboard focus, before
434 rxvt-unicode does focus out processing.
435
436 on_configure_notify $term, $event
437 on_property_notify $term, $event
438 on_key_press $term, $event, $keysym, $octets
439 on_key_release $term, $event, $keysym
440 on_button_press $term, $event
441 on_button_release $term, $event
442 on_motion_notify $term, $event
443 on_map_notify $term, $event
444 on_unmap_notify $term, $event
445 Called whenever the corresponding X event is received for the
446 terminal If the hook returns true, then the even will be ignored by
447 rxvt-unicode.
448
449 The event is a hash with most values as named by Xlib (see the
450 XEvent manpage), with the additional members "row" and "col", which
451 are the (real, not screen-based) row and column under the mouse
452 cursor.
453
454 "on_key_press" additionally receives the string rxvt-unicode would
455 output, if any, in locale-specific encoding.
456
457 subwindow.
458
459 on_client_message $term, $event
460 on_wm_protocols $term, $event
461 on_wm_delete_window $term, $event
462 Called when various types of ClientMessage events are received (all
463 with format=32, WM_PROTOCOLS or WM_PROTOCOLS:WM_DELETE_WINDOW).
464
465 Variables in the "urxvt" Package
466 $urxvt::LIBDIR
467 The rxvt-unicode library directory, where, among other things, the
468 perl modules and scripts are stored.
469
470 $urxvt::RESCLASS, $urxvt::RESCLASS
471 The resource class and name rxvt-unicode uses to look up X
472 resources.
473
474 $urxvt::RXVTNAME
475 The basename of the installed binaries, usually "urxvt".
476
477 $urxvt::TERM
478 The current terminal. This variable stores the current "urxvt::term"
479 object, whenever a callback/hook is executing.
480
481 @urxvt::TERM_INIT
482 All coderefs in this array will be called as methods of the next
483 newly created "urxvt::term" object (during the "on_init" phase). The
484 array gets cleared before the codereferences that were in it are
485 being executed, so coderefs can push themselves onto it again if
486 they so desire.
487
488 This complements to the perl-eval commandline option, but gets

491 @urxvt::TERM_EXT
492 Works similar to @TERM_INIT, but contains perl package/class names,
493 which get registered as normal extensions after calling the hooks in
494 @TERM_INIT but before other extensions. Gets cleared just like
495 @TERM_INIT.

537 RENDITION
538 Rendition bitsets contain information about colour, font, font styles
539 and similar information for each screen cell.
540
541 The following "macros" deal with changes in rendition sets. You should
542 never just create a bitset, you should always modify an existing one, as
543 they contain important information required for correct operation of
544 rxvt-unicode.
545
546 $rend = urxvt::DEFAULT_RSTYLE
547 Returns the default rendition, as used when the terminal is starting
548 up or being reset. Useful as a base to start when creating
549 renditions.
550
551 $rend = urxvt::OVERLAY_RSTYLE
552 Return the rendition mask used for overlays by default.
553
554 $rendbit = urxvt::RS_Bold, RS_Italic, RS_Blink, RS_RVid, RS_Uline
555 Return the bit that enabled bold, italic, blink, reverse-video and
556 underline, respectively. To enable such a style, just logically OR
557 it into the bitset.
558
559 $foreground = urxvt::GET_BASEFG $rend
560 $background = urxvt::GET_BASEBG $rend
561 Return the foreground/background colour index, respectively.
562
563 $rend = urxvt::SET_FGCOLOR $rend, $new_colour
564 $rend = urxvt::SET_BGCOLOR $rend, $new_colour
565 Replace the foreground/background colour in the rendition mask with
566 the specified one.
567
568 $value = urxvt::GET_CUSTOM $rend
569 Return the "custom" value: Every rendition has 5 bits for use by
570 extensions. They can be set and changed as you like and are
571 initially zero.
572
573 $rend = urxvt::SET_CUSTOM $rend, $new_value
574 Change the custom value.
575
576 The "urxvt::anyevent" Class
577 The sole purpose of this class is to deliver an interface to the
578 "AnyEvent" module - any module using it will work inside urxvt without
579 further programming. The only exception is that you cannot wait on
580 condition variables, but non-blocking condvar use is ok. What this means
581 is that you cannot use blocking APIs, but the non-blocking variant
582 should work.
583
134 The "urxvt::term" Class 584 The "urxvt::term" Class
585 $term = new urxvt::term $envhashref, $rxvtname, [arg...]
586 Creates a new terminal, very similar as if you had started it with
587 system "$rxvtname, arg...". $envhashref must be a reference to a
588 %ENV-like hash which defines the environment of the new terminal.
589
590 Croaks (and probably outputs an error message) if the new instance
591 couldn't be created. Returns "undef" if the new instance didn't
592 initialise perl, and the terminal object otherwise. The "init" and
593 "start" hooks will be called during this call.
594
595 $term->destroy
596 Destroy the terminal object (close the window, free resources etc.).
597 Please note that rxvt will not exit as long as any event watchers
598 (timers, io watchers) are still active.
599
600 $term->exec_async ($cmd[, @args])
601 Works like the combination of the "fork"/"exec" builtins, which
602 executes ("starts") programs in the background. This function takes
603 care of setting the user environment before exec'ing the command
604 (e.g. "PATH") and should be preferred over explicit calls to "exec"
605 or "system".
606
607 Returns the pid of the subprocess or "undef" on error.
608
609 $isset = $term->option ($optval[, $set])
610 Returns true if the option specified by $optval is enabled, and
611 optionally change it. All option values are stored by name in the
612 hash %urxvt::OPTION. Options not enabled in this binary are not in
613 the hash.

660 $value = $term->x_resource ($pattern)
661 Returns the X-Resource for the given pattern, excluding the program
662 or class name, i.e. "$term->x_resource ("boldFont")" should return
663 the same value as used by this instance of rxvt-unicode. Returns
664 "undef" if no resource with that pattern exists.
665
666 This method should only be called during the "on_start" hook, as
667 there is only one resource database per display, and later
668 invocations might return the wrong resources.
669
670 $success = $term->parse_keysym ($keysym_spec, $command_string)
671 Adds a keymap translation exactly as specified via a resource. See
672 the "keysym" resource in the rxvt(1) manpage.
673
674 $rend = $term->rstyle ([$new_rstyle])
675 Return and optionally change the current rendition. Text that is
676 output by the terminal application will use this style.
677
678 ($row, $col) = $term->screen_cur ([$row, $col])
679 Return the current coordinates of the text cursor position and
680 optionally set it (which is usually bad as applications don't expect
681 that).
168 682
169 ($row, $col) = $term->selection_mark ([$row, $col]) 683 ($row, $col) = $term->selection_mark ([$row, $col])
170 ($row, $col) = $term->selection_beg ([$row, $col]) 684 ($row, $col) = $term->selection_beg ([$row, $col])
171 ($row, $col) = $term->selection_end ([$row, $col]) 685 ($row, $col) = $term->selection_end ([$row, $col])
172 Return the current values of the selection mark, begin or end 686 Return the current values of the selection mark, begin or end
173 positions, and optionally set them to new values. 687 positions, and optionally set them to new values.
174 688
689 $term->selection_make ($eventtime[, $rectangular])
690 Tries to make a selection as set by "selection_beg" and
691 "selection_end". If $rectangular is true (default: false), a
692 rectangular selection will be made. This is the prefered function to
693 make a selection.
694
175 $success = $term->selection_grab ($eventtime) 695 $success = $term->selection_grab ($eventtime)
176 Try to request the primary selection from the server (for example, 696 Try to request the primary selection text from the server (for
177 as set by the next method). 697 example, as set by the next method). No visual feedback will be
698 given. This function is mostly useful from within "on_sel_grab"
699 hooks.
178 700
179 $oldtext = $term->selection ([$newtext]) 701 $oldtext = $term->selection ([$newtext])
180 Return the current selection text and optionally replace it by 702 Return the current selection text and optionally replace it by
181 $newtext. 703 $newtext.
182 704
183 $term->scr_overlay ($x, $y, $text) 705 $term->overlay_simple ($x, $y, $text)
184 Create a simple multi-line overlay box. See the next method for 706 Create a simple multi-line overlay box. See the next method for
185 details. 707 details.
186 708
187 $term->scr_overlay_new ($x, $y, $width, $height) 709 $term->overlay ($x, $y, $width, $height[, $rstyle[, $border]])
188 Create a new (empty) overlay at the given position with the given 710 Create a new (empty) overlay at the given position with the given
189 width/height. A border will be put around the box. If either $x or 711 width/height. $rstyle defines the initial rendition style (default:
712 "OVERLAY_RSTYLE").
713
714 If $border is 2 (default), then a decorative border will be put
715 around the box.
716
190 $y is negative, then this is counted from the right/bottom side, 717 If either $x or $y is negative, then this is counted from the
191 respectively. 718 right/bottom side, respectively.
192 719
193 $term->scr_overlay_off 720 This method returns an urxvt::overlay object. The overlay will be
194 Switch the overlay off again. 721 visible as long as the perl object is referenced.
195 722
196 $term->scr_overlay_set_char ($x, $y, $char, $rend = OVERLAY_RSTYLE) 723 The methods currently supported on "urxvt::overlay" objects are:
197 Put a single character (specified numerically) at the given overlay
198 position.
199 724
200 $term->scr_overlay_set ($x, $y, $text) 725 $overlay->set ($x, $y, $text, $rend)
201 Write a string at the given position into the overlay. 726 Similar to "$term->ROW_t" and "$term->ROW_r" in that it puts
727 text in rxvt-unicode's special encoding and an array of
728 rendition values at a specific position inside the overlay.
202 729
730 $overlay->hide
731 If visible, hide the overlay, but do not destroy it.
732
733 $overlay->show
734 If hidden, display the overlay again.
735
736 $popup = $term->popup ($event)
737 Creates a new "urxvt::popup" object that implements a popup menu.
738 The $event *must* be the event causing the menu to pop up (a button
739 event, currently).
740
203 $cellwidth = $term->strwidth $string 741 $cellwidth = $term->strwidth ($string)
204 Returns the number of screen-cells this string would need. Correctly 742 Returns the number of screen-cells this string would need. Correctly
205 accounts for wide and combining characters. 743 accounts for wide and combining characters.
206 744
207 $octets = $term->locale_encode $string 745 $octets = $term->locale_encode ($string)
208 Convert the given text string into the corresponding locale 746 Convert the given text string into the corresponding locale
209 encoding. 747 encoding.
210 748
211 $string = $term->locale_decode $octets 749 $string = $term->locale_decode ($octets)
212 Convert the given locale-encoded octets into a perl string. 750 Convert the given locale-encoded octets into a perl string.
751
752 $term->scr_xor_span ($beg_row, $beg_col, $end_row, $end_col[, $rstyle])
753 XORs the rendition values in the given span with the provided value
754 (default: "RS_RVid"), which *MUST NOT* contain font styles. Useful
755 in refresh hooks to provide effects similar to the selection.
756
757 $term->scr_xor_rect ($beg_row, $beg_col, $end_row, $end_col[, $rstyle1[,
758 $rstyle2]])
759 Similar to "scr_xor_span", but xors a rectangle instead. Trailing
760 whitespace will additionally be xored with the $rstyle2, which
761 defaults to "RS_RVid | RS_Uline", which removes reverse video again
762 and underlines it instead. Both styles *MUST NOT* contain font
763 styles.
764
765 $term->scr_bell
766 Ring the bell!
767
768 $term->scr_add_lines ($string)
769 Write the given text string to the screen, as if output by the
770 application running inside the terminal. It may not contain command
771 sequences (escape codes), but is free to use line feeds, carriage
772 returns and tabs. The string is a normal text string, not in
773 locale-dependent encoding.
774
775 Normally its not a good idea to use this function, as programs might
776 be confused by changes in cursor position or scrolling. Its useful
777 inside a "on_add_lines" hook, though.
778
779 $term->scr_change_screen ($screen)
780 Switch to given screen - 0 primary, 1 secondary.
781
782 $term->cmd_parse ($octets)
783 Similar to "scr_add_lines", but the argument must be in the
784 locale-specific encoding of the terminal and can contain command
785 sequences (escape codes) that will be interpreted.
213 786
214 $term->tt_write ($octets) 787 $term->tt_write ($octets)
215 Write the octets given in $data to the tty (i.e. as program input). 788 Write the octets given in $data to the tty (i.e. as program input).
216 To pass characters instead of octets, you should convetr you strings 789 To pass characters instead of octets, you should convert your
217 first to the locale-specific encoding using "$term->locale_encode". 790 strings first to the locale-specific encoding using
791 "$term->locale_encode".
792
793 $old_events = $term->pty_ev_events ([$new_events])
794 Replaces the event mask of the pty watcher by the given event mask.
795 Can be used to suppress input and output handling to the pty/tty.
796 See the description of "urxvt::timer->events". Make sure to always
797 restore the previous value.
798
799 $windowid = $term->parent
800 Return the window id of the toplevel window.
801
802 $windowid = $term->vt
803 Return the window id of the terminal window.
804
805 $term->vt_emask_add ($x_event_mask)
806 Adds the specified events to the vt event mask. Useful e.g. when you
807 want to receive pointer events all the times:
808
809 $term->vt_emask_add (urxvt::PointerMotionMask);
810
811 $window_width = $term->width
812 $window_height = $term->height
813 $font_width = $term->fwidth
814 $font_height = $term->fheight
815 $font_ascent = $term->fbase
816 $terminal_rows = $term->nrow
817 $terminal_columns = $term->ncol
818 $has_focus = $term->focus
819 $is_mapped = $term->mapped
820 $max_scrollback = $term->saveLines
821 $nrow_plus_saveLines = $term->total_rows
822 $topmost_scrollback_row = $term->top_row
823 Return various integers describing terminal characteristics.
824
825 $x_display = $term->display_id
826 Return the DISPLAY used by rxvt-unicode.
827
828 $lc_ctype = $term->locale
829 Returns the LC_CTYPE category string used by this rxvt-unicode.
830
831 $env = $term->env
832 Returns a copy of the environment in effect for the terminal as a
833 hashref similar to "\%ENV".
834
835 $modifiermask = $term->ModLevel3Mask
836 $modifiermask = $term->ModMetaMask
837 $modifiermask = $term->ModNumLockMask
838 Return the modifier masks corresponding to the "ISO Level 3 Shift"
839 (often AltGr), the meta key (often Alt) and the num lock key, if
840 applicable.
841
842 $screen = $term->current_screen
843 Returns the currently displayed screen (0 primary, 1 secondary).
844
845 $view_start = $term->view_start ([$newvalue])
846 Returns the row number of the topmost displayed line. Maximum value
847 is 0, which displays the normal terminal contents. Lower values
848 scroll this many lines into the scrollback buffer.
849
850 $term->want_refresh
851 Requests a screen refresh. At the next opportunity, rxvt-unicode
852 will compare the on-screen display with its stored representation.
853 If they differ, it redraws the differences.
854
855 Used after changing terminal contents to display them.
856
857 $text = $term->ROW_t ($row_number[, $new_text[, $start_col]])
858 Returns the text of the entire row with number $row_number. Row 0 is
859 the topmost terminal line, row "$term->$ncol-1" is the bottommost
860 terminal line. The scrollback buffer starts at line -1 and extends
861 to line "-$term->nsaved". Nothing will be returned if a nonexistent
862 line is requested.
863
864 If $new_text is specified, it will replace characters in the current
865 line, starting at column $start_col (default 0), which is useful to
866 replace only parts of a line. The font index in the rendition will
867 automatically be updated.
868
869 $text is in a special encoding: tabs and wide characters that use
870 more than one cell when displayed are padded with $urxvt::NOCHAR
871 characters. Characters with combining characters and other
872 characters that do not fit into the normal tetx encoding will be
873 replaced with characters in the private use area.
874
875 You have to obey this encoding when changing text. The advantage is
876 that "substr" and similar functions work on screen cells and not on
877 characters.
878
879 The methods "$term->special_encode" and "$term->special_decode" can
880 be used to convert normal strings into this encoding and vice versa.
881
882 $rend = $term->ROW_r ($row_number[, $new_rend[, $start_col]])
883 Like "$term->ROW_t", but returns an arrayref with rendition bitsets.
884 Rendition bitsets contain information about colour, font, font
885 styles and similar information. See also "$term->ROW_t".
886
887 When setting rendition, the font mask will be ignored.
888
889 See the section on RENDITION, above.
890
891 $length = $term->ROW_l ($row_number[, $new_length])
892 Returns the number of screen cells that are in use ("the line
893 length"). Unlike the urxvt core, this returns "$term->ncol" if the
894 line is joined with the following one.
895
896 $bool = $term->is_longer ($row_number)
897 Returns true if the row is part of a multiple-row logical "line"
898 (i.e. joined with the following row), which means all characters are
899 in use and it is continued on the next row (and possibly a
900 continuation of the previous row(s)).
901
902 $line = $term->line ($row_number)
903 Create and return a new "urxvt::line" object that stores information
904 about the logical line that row $row_number is part of. It supports
905 the following methods:
906
907 $text = $line->t ([$new_text])
908 Returns or replaces the full text of the line, similar to
909 "ROW_t"
910
911 $rend = $line->r ([$new_rend])
912 Returns or replaces the full rendition array of the line,
913 similar to "ROW_r"
914
915 $length = $line->l
916 Returns the length of the line in cells, similar to "ROW_l".
917
918 $rownum = $line->beg
919 $rownum = $line->end
920 Return the row number of the first/last row of the line,
921 respectively.
922
923 $offset = $line->offset_of ($row, $col)
924 Returns the character offset of the given row|col pair within
925 the logical line. Works for rows outside the line, too, and
926 returns corresponding offsets outside the string.
927
928 ($row, $col) = $line->coord_of ($offset)
929 Translates a string offset into terminal coordinates again.
930
931 $text = $term->special_encode $string
932 Converts a perl string into the special encoding used by
933 rxvt-unicode, where one character corresponds to one screen cell.
934 See "$term->ROW_t" for details.
935
936 $string = $term->special_decode $text
937 Converts rxvt-unicodes text reprsentation into a perl string. See
938 "$term->ROW_t" for details.
939
940 $success = $term->grab_button ($button, $modifiermask)
941 Registers a synchronous button grab. See the XGrabButton manpage.

943 $success = $term->grab ($eventtime[, $sync])
944 Calls XGrabPointer and XGrabKeyboard in asynchronous (default) or
945 synchronous ($sync is true). Also remembers the grab timestampe.
946
947 $term->allow_events_async
948 Calls XAllowEvents with AsyncBoth for the most recent grab.
949
950 $term->allow_events_sync
951 Calls XAllowEvents with SyncBoth for the most recent grab.
952
953 $term->allow_events_replay
954 Calls XAllowEvents with both ReplayPointer and ReplayKeyboard for
955 the most recent grab.
956
957 $term->ungrab
958 Calls XUngrab for the most recent grab. Is called automatically on
959 evaluation errors, as it is better to lose the grab in the error
960 case as the session.
