35 Intelligent selection. This extension tries to be more intelligent 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
36 when the user extends selections (double-click). Right now, it tries 40 intelligent when the user extends selections (double-click and
37 to select urls and complete shell-quoted arguments, which is very 41 further clicks). Right now, it tries to select words, urls and
42 complete shell-quoted arguments, which is very convenient, too, if
38 convenient, too, if your ls supports "--quoting-style=shell". 43 your ls supports "--quoting-style=shell".
39 44
40 It also offers the following bindable event: 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 Another example: Programs I use often output "absolute path: " at
64 the beginning of a line when they process multiple files. The
65 following pattern matches the filename (note, there is a single
66 space at the very end):
67
68 URxvt.selection.pattern-0: ^(/[^:]+):\
69
70 You can look at the source of the selection extension to see more
71 interesting uses, such as parsing a line from beginning to end.
72
73 This extension also offers following bindable keyboard commands:
41 74
42 rot13 75 rot13
43 Rot-13 the selection when activated. Used via keyboard trigger: 76 Rot-13 the selection when activated. Used via keyboard trigger:

45 URxvt.keysym.C-M-r: perl:selection:rot13 78 URxvt.keysym.C-M-r: perl:selection:rot13
46 79
80 option-popup (enabled by default)
81 Binds a popup menu to Ctrl-Button2 that lets you toggle (some)
82 options at runtime.
83
84 Other extensions can extend this popup menu by pushing a code
85 reference onto "@{ $term-"{option_popup_hook} }>, which gets called
86 whenever the popup is being displayed.
87
88 It's sole argument is the popup menu, which can be modified. It
89 should either return nothing or a string, the initial boolean value
90 and a code reference. The string will be used as button text and the
91 code reference will be called when the toggle changes, with the new
92 boolean value as first argument.
93
94 The following will add an entry "myoption" that changes
95 "$self-"{myoption}>:
96
97 push @{ $self->{term}{option_popup_hook} }, sub {
98 ("my option" => $myoption, sub { $self->{myoption} = $_[0] })
99 };
100
101 selection-popup (enabled by default)
102 Binds a popup menu to Ctrl-Button3 that lets you convert the
103 selection text into various other formats/action (such as uri
104 unescaping, perl evaluation, web-browser starting etc.), depending
105 on content.
106
107 Other extensions can extend this popup menu by pushing a code
108 reference onto "@{ $term-"{selection_popup_hook} }>, which gets
109 called whenever the popup is being displayed.
110
111 It's sole argument is the popup menu, which can be modified. The
112 selection is in $_, which can be used to decide wether to add
113 something or not. It should either return nothing or a string and a
114 code reference. The string will be used as button text and the code
115 reference will be called when the button gets activated and should
116 transform $_.
117
118 The following will add an entry "a to b" that transforms all "a"s in
119 the selection to "b"s, but only if the selection currently contains
120 any "a"s:
121
122 push @{ $self->{term}{selection_popup_hook} }, sub {
123 /a/ ? ("a to be" => sub { s/a/b/g }
124 : ()
125 };
126
127 searchable-scrollback<hotkey> (enabled by default)
128 Adds regex search functionality to the scrollback buffer, triggered
129 by a hotkey (default: "M-s"). While in search mode, normal terminal
130 input/output is suspended and a regex is displayed at the bottom of
131 the screen.
132
133 Inputting characters appends them to the regex and continues
134 incremental search. "BackSpace" removes a character from the regex,
135 "Up" and "Down" search upwards/downwards in the scrollback buffer,
136 "End" jumps to the bottom. "Escape" leaves search mode and returns
137 to the point where search was started, while "Enter" or "Return"
138 stay at the current position and additionally stores the first match
139 in the current line into the primary selection.
140
141 The regex defaults to "(?i)", resulting in a case-insensitive
142 search. To get a case-sensitive search you can delete this prefix
143 using "BackSpace" or simply use an uppercase character which removes
144 the "(?i)" prefix.
145
146 See perlre for more info about perl regular expression syntax.
147
148 readline (enabled by default)
149 A support package that tries to make editing with readline easier.
150 At the moment, it reacts to clicking shift-left mouse button by
151 trying to move the text cursor to this position. It does so by
152 generating as many cursor-left or cursor-right keypresses as
153 required (the this only works for programs that correctly support
154 wide characters).
155
156 To avoid too many false positives, this is only done when:
157
158 - the tty is in ICANON state.
159 - the text cursor is visible.
160 - the primary screen is currently being displayed.
161 - the mouse is on the same (multi-row-) line as the text cursor.
162
163 The normal selection mechanism isn't disabled, so quick successive
164 clicks might interfere with selection creation in harmless ways.
165
166 selection-autotransform
167 This selection allows you to do automatic transforms on a selection
168 whenever a selection is made.
169
170 It works by specifying perl snippets (most useful is a single "s///"
171 operator) that modify $_ as resources:
172
173 URxvt.selection-autotransform.0: transform
174 URxvt.selection-autotransform.1: transform
175 ...
176
177 For example, the following will transform selections of the form
178 "filename:number", often seen in compiler messages, into "vi
179 +$filename $word":
180
181 URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/
182
183 And this example matches the same,but replaces it with vi-commands
184 you can paste directly into your (vi :) editor:
185
186 URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/
187
188 Of course, this can be modified to suit your needs and your editor
189 :)
190
191 To expand the example above to typical perl error messages ("XXX at
192 FILENAME line YYY."), you need a slightly more elaborate solution:
193
194 URxvt.selection.pattern-0: ( at .*? line \\d+[,.])
195 URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/
196
197 The first line tells the selection code to treat the unchanging part
198 of every error message as a selection pattern, and the second line
199 transforms the message into vi commands to load the file.
200
201 tabbed
202 This transforms the terminal into a tabbar with additional
203 terminals, that is, it implements what is commonly refered to as
204 "tabbed terminal". The topmost line displays a "[NEW]" button,
205 which, when clicked, will add a new tab, followed by one button per
206 tab.
207
208 Clicking a button will activate that tab. Pressing Shift-Left and
209 Shift-Right will switch to the tab left or right of the current one,
210 while Shift-Down creates a new tab.
211
212 The tabbar itself can be configured similarly to a normal terminal,
213 but with a resource class of "URxvt.tabbed". In addition, it
214 supports the following four resources (shown with defaults):
215
216 URxvt.tabbed.tabbar-fg: <colour-index, default 3>
217 URxvt.tabbed.tabbar-bg: <colour-index, default 0>
218 URxvt.tabbed.tab-fg: <colour-index, default 0>
219 URxvt.tabbed.tab-bg: <colour-index, default 1>
220
221 See *COLOR AND GRAPHICS* in the rxvt(1) manpage for valid indices.
222
223 mark-urls
224 Uses per-line display filtering ("on_line_update") to underline urls
225 and make them clickable. When middle-clicked, the program specified
226 in the resource "urlLauncher" (default "x-www-browser") will be
227 started with the URL as first argument.
228
229 xim-onthespot
230 This (experimental) perl extension implements OnTheSpot editing. It
231 does not work perfectly, and some input methods don't seem to work
232 well with OnTheSpot editing in general, but it seems to work at
233 leats for SCIM and kinput2.
234
235 You enable it by specifying this extension and a preedit style of
236 "OnTheSpot", i.e.:
237
238 rxvt -pt OnTheSpot -pe xim-onthespot
239
240 kuake<hotkey>
241 A very primitive quake-console-like extension. It was inspired by a
242 description of how the programs "kuake" and "yakuake" work: Whenever
243 the user presses a global accelerator key (by default "F10"), the
244 terminal will show or hide itself. Another press of the accelerator
245 key will hide or show it again.
246
247 Initially, the window will not be shown when using this extension.
248
249 This is useful if you need a single terminal thats not using any
250 desktop space most of the time but is quickly available at the press
251 of a key.
252
253 The accelerator key is grabbed regardless of any modifers, so this
254 extension will actually grab a physical key just for this function.
255
256 If you want a quake-like animation, tell your window manager to do
257 so (fvwm can do it).
258
259 automove-background
260 This is basically a very small extension that dynamically changes
261 the background pixmap offset to the window position, in effect
262 creating the same effect as pseudo transparency with a custom
263 pixmap. No scaling is supported in this mode. Exmaple:
264
265 rxvt -pixmap background.xpm -pe automove-background
266
267 block-graphics-to-ascii
268 A not very useful example of filtering all text output to the
269 terminal by replacing all line-drawing characters (U+2500 .. U+259F)
270 by a similar-looking ascii character.
271
47 digital-clock 272 digital-clock
48 Displays a digital clock using the built-in overlay. 273 Displays a digital clock using the built-in overlay.
274
275 remote-clipboard
276 Somewhat of a misnomer, this extension adds two menu entries to the
277 selection popup that allows one ti run external commands to store
278 the selection somewhere and fetch it again.
279
280 We use it to implement a "distributed selection mechanism", which
281 just means that one command uploads the file to a remote server, and
282 another reads it.
283
284 The commands can be set using the "URxvt.remote-selection.store" and
285 "URxvt.remote-selection.fetch" resources. The first should read the
286 selection to store from STDIN (always in UTF-8), the second should
287 provide the selection data on STDOUT (also in UTF-8).
288
289 The defaults (which are likely useless to you) use rsh and cat:
290
291 URxvt.remote-selection.store: rsh ruth 'cat >/tmp/distributed-selection'
292 URxvt.remote-selection.fetch: rsh ruth 'cat /tmp/distributed-selection'
293
294 selection-pastebin
295 This is a little rarely useful extension that Uploads the selection
296 as textfile to a remote site (or does other things). (The
297 implementation is not currently secure for use in a multiuser
298 environment as it writes to /tmp directly.).
299
300 It listens to the "selection-pastebin:remote-pastebin" keyboard
301 command, i.e.
302
303 URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
304
305 Pressing this combination runs a command with "%" replaced by the
306 name of the textfile. This command can be set via a resource:
307
308 URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
309
310 And the default is likely not useful to anybody but the few people
311 around here :)
312
313 The name of the textfile is the hex encoded md5 sum of the
314 selection, so the same content should lead to the same filename.
315
316 After a successful upload the selection will be replaced by the text
317 given in the "selection-pastebin-url" resource (again, the % is the
318 placeholder for the filename):
319
320 URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/%
49 321

66 339
340 Argument names also often indicate the type of a parameter. Here are
341 some hints on what they mean:
342
343 $text
344 Rxvt-unicodes special way of encoding text, where one "unicode"
345 character always represents one screen cell. See ROW_t for a
346 discussion of this format.
347
348 $string
349 A perl text string, with an emphasis on *text*. It can store all
350 unicode characters and is to be distinguished with text encoded in a
351 specific encoding (often locale-specific) and binary data.
352
353 $octets
354 Either binary data or - more common - a text string encoded in a
355 locale-specific way.
356
357 Extension Objects
358 Every perl extension is a perl class. A separate perl object is created
359 for each terminal and each extension and passed as the first parameter
360 to hooks. So extensions can use their $self object without having to
361 think about other extensions, with the exception of methods and members
362 that begin with an underscore character "_": these are reserved for
363 internal use.
364
365 Although it isn't a "urxvt::term" object, you can call all methods of
366 the "urxvt::term" class on this object.
367
368 It has the following methods and data members:
369
370 $urxvt_term = $self->{term}
371 Returns the "urxvt::term" object associated with this instance of
372 the extension. This member *must not* be changed in any way.
373
374 $self->enable ($hook_name => $cb, [$hook_name => $cb..])
375 Dynamically enable the given hooks (named without the "on_" prefix)
376 for this extension, replacing any previous hook. This is useful when
377 you want to overwrite time-critical hooks only temporarily.
378
379 $self->disable ($hook_name[, $hook_name..])
380 Dynamically disable the given hooks.
381

159 486
487 on_add_lines $term, $string
488 Called whenever text is about to be output, with the text as
489 argument. You can filter/change and output the text yourself by
490 returning a true value and calling "$term->scr_add_lines" yourself.
491 Please note that this might be very slow, however, as your hook is
492 called for all text being output.
493
494 on_tt_write $term, $octets
495 Called whenever some data is written to the tty/pty and can be used
496 to suppress or filter tty input.
497
498 on_line_update $term, $row
499 Called whenever a line was updated or changed. Can be used to filter
500 screen output (e.g. underline urls or other useless stuff). Only
501 lines that are being shown will be filtered, and, due to performance
502 reasons, not always immediately.
503
504 The row number is always the topmost row of the line if the line
505 spans multiple rows.
506
507 Please note that, if you change the line, then the hook might get
508 called later with the already-modified line (e.g. if unrelated parts
509 change), so you cannot just toggle rendition bits, but only set
510 them.
511
160 on_refresh_begin $term 512 on_refresh_begin $term
161 Called just before the screen gets redrawn. Can be used for overlay 513 Called just before the screen gets redrawn. Can be used for overlay
162 or similar effects by modify terminal contents in refresh_begin, and 514 or similar effects by modify terminal contents in refresh_begin, and
163 restoring them in refresh_end. The built-in overlay and selection 515 restoring them in refresh_end. The built-in overlay and selection
164 display code is run after this hook, and takes precedence. 516 display code is run after this hook, and takes precedence.
165 517
166 on_refresh_end $term 518 on_refresh_end $term
167 Called just after the screen gets redrawn. See "on_refresh_begin". 519 Called just after the screen gets redrawn. See "on_refresh_begin".
168 520
169 on_keyboard_command $term, $string 521 on_user_command $term, $string
170 Called whenever the user presses a key combination that has a 522 Called whenever the a user-configured event is being activated (e.g.
171 "perl:string" action bound to it (see description of the keysym 523 via a "perl:string" action bound to a key, see description of the
172 resource in the rxvt(1) manpage). 524 keysym resource in the rxvt(1) manpage).
525
526 The event is simply the action string. This interface is assumed to
527 change slightly in the future.
528
529 on_resize_all_windows $tern, $new_width, $new_height
530 Called just after the new window size has been calculcated, but
531 before windows are actually being resized or hints are being set. If
532 this hook returns TRUE, setting of the window hints is being
533 skipped.
534
535 on_x_event $term, $event
536 Called on every X event received on the vt window (and possibly
537 other windows). Should only be used as a last resort. Most event
538 structure members are not passed.
539
540 on_root_event $term, $event
541 Like "on_x_event", but is called for events on the root window.
542
543 on_focus_in $term
544 Called whenever the window gets the keyboard focus, before
545 rxvt-unicode does focus in processing.
546
547 on_focus_out $term
548 Called wheneever the window loses keyboard focus, before
549 rxvt-unicode does focus out processing.
550
551 on_configure_notify $term, $event
552 on_property_notify $term, $event
553 on_key_press $term, $event, $keysym, $octets

556 on_button_release $term, $event
557 on_motion_notify $term, $event
558 on_map_notify $term, $event
559 on_unmap_notify $term, $event
560 Called whenever the corresponding X event is received for the
561 terminal If the hook returns true, then the even will be ignored by
562 rxvt-unicode.
563
564 The event is a hash with most values as named by Xlib (see the
565 XEvent manpage), with the additional members "row" and "col", which
566 are the (real, not screen-based) row and column under the mouse
567 cursor.
568
569 "on_key_press" additionally receives the string rxvt-unicode would
570 output, if any, in locale-specific encoding.
571
572 subwindow.
573
574 on_client_message $term, $event
575 on_wm_protocols $term, $event
576 on_wm_delete_window $term, $event
577 Called when various types of ClientMessage events are received (all
578 with format=32, WM_PROTOCOLS or WM_PROTOCOLS:WM_DELETE_WINDOW).
173 579
174 Variables in the "urxvt" Package 580 Variables in the "urxvt" Package

582 The rxvt-unicode library directory, where, among other things, the
583 perl modules and scripts are stored.

585 $urxvt::RESCLASS, $urxvt::RESCLASS
586 The resource class and name rxvt-unicode uses to look up X
587 resources.

594 object, whenever a callback/hook is executing.
595
596 @urxvt::TERM_INIT
597 All coderefs in this array will be called as methods of the next
598 newly created "urxvt::term" object (during the "on_init" phase). The
599 array gets cleared before the codereferences that were in it are
600 being executed, so coderefs can push themselves onto it again if
601 they so desire.
602
603 This complements to the perl-eval commandline option, but gets
604 executed first.
605
606 @urxvt::TERM_EXT
607 Works similar to @TERM_INIT, but contains perl package/class names,
608 which get registered as normal extensions after calling the hooks in
609 @TERM_INIT but before other extensions. Gets cleared just like
610 @TERM_INIT.

630 regardless of wether they are started, being destroyed etc., so be
631 careful. Only term objects that have perl extensions attached will
632 be returned (because there is no urxvt::term objet associated with
633 others).

233 Change the custom value. 697 Change the custom value.
234 698
699 The "urxvt::anyevent" Class
700 The sole purpose of this class is to deliver an interface to the
701 "AnyEvent" module - any module using it will work inside urxvt without
702 further programming. The only exception is that you cannot wait on
703 condition variables, but non-blocking condvar use is ok. What this means
704 is that you cannot use blocking APIs, but the non-blocking variant
705 should work.
706
235 The "urxvt::term" Class 707 The "urxvt::term" Class
708 $term = new urxvt::term $envhashref, $rxvtname, [arg...]
709 Creates a new terminal, very similar as if you had started it with
710 system "$rxvtname, arg...". $envhashref must be a reference to a
711 %ENV-like hash which defines the environment of the new terminal.
712
713 Croaks (and probably outputs an error message) if the new instance
714 couldn't be created. Returns "undef" if the new instance didn't
715 initialise perl, and the terminal object otherwise. The "init" and
716 "start" hooks will be called before this call returns, and are free
717 to refer to global data (which is race free).
718
719 $term->destroy
720 Destroy the terminal object (close the window, free resources etc.).
721 Please note that rxvt will not exit as long as any event watchers
722 (timers, io watchers) are still active.
723
724 $term->exec_async ($cmd[, @args])
725 Works like the combination of the "fork"/"exec" builtins, which
726 executes ("starts") programs in the background. This function takes
727 care of setting the user environment before exec'ing the command
728 (e.g. "PATH") and should be preferred over explicit calls to "exec"
729 or "system".
730
731 Returns the pid of the subprocess or "undef" on error.
732
733 $isset = $term->option ($optval[, $set])
734 Returns true if the option specified by $optval is enabled, and
735 optionally change it. All option values are stored by name in the
736 hash %urxvt::OPTION. Options not enabled in this binary are not in
737 the hash.

238 optionally sets a new value. Setting values is most useful in the 751 optionally sets a new value. Setting values is most useful in the

784 $value = $term->x_resource ($pattern)
785 Returns the X-Resource for the given pattern, excluding the program
786 or class name, i.e. "$term->x_resource ("boldFont")" should return
787 the same value as used by this instance of rxvt-unicode. Returns
788 "undef" if no resource with that pattern exists.
789
790 This method should only be called during the "on_start" hook, as
791 there is only one resource database per display, and later
792 invocations might return the wrong resources.
793
794 $success = $term->parse_keysym ($keysym_spec, $command_string)
795 Adds a keymap translation exactly as specified via a resource. See
796 the "keysym" resource in the rxvt(1) manpage.
797
798 $rend = $term->rstyle ([$new_rstyle])
799 Return and optionally change the current rendition. Text that is
800 output by the terminal application will use this style.
801
802 ($row, $col) = $term->screen_cur ([$row, $col])
803 Return the current coordinates of the text cursor position and
804 optionally set it (which is usually bad as applications don't expect
805 that).
269 806
270 ($row, $col) = $term->selection_mark ([$row, $col]) 807 ($row, $col) = $term->selection_mark ([$row, $col])

272 ($row, $col) = $term->selection_end ([$row, $col]) 809 ($row, $col) = $term->selection_end ([$row, $col])
273 Return the current values of the selection mark, begin or end 810 Return the current values of the selection mark, begin or end
274 positions, and optionally set them to new values. 811 positions, and optionally set them to new values.
275 812
813 $term->selection_make ($eventtime[, $rectangular])
814 Tries to make a selection as set by "selection_beg" and
815 "selection_end". If $rectangular is true (default: false), a
816 rectangular selection will be made. This is the prefered function to
817 make a selection.
818
276 $success = $term->selection_grab ($eventtime) 819 $success = $term->selection_grab ($eventtime)
277 Try to request the primary selection from the server (for example, 820 Try to request the primary selection text from the server (for
278 as set by the next method). 821 example, as set by the next method). No visual feedback will be
822 given. This function is mostly useful from within "on_sel_grab"
823 hooks.
279 824
280 $oldtext = $term->selection ([$newtext]) 825 $oldtext = $term->selection ([$newtext])
281 Return the current selection text and optionally replace it by 826 Return the current selection text and optionally replace it by
282 $newtext. 827 $newtext.

863 event, currently).
864
327 $cellwidth = $term->strwidth $string 865 $cellwidth = $term->strwidth ($string)
328 Returns the number of screen-cells this string would need. Correctly 866 Returns the number of screen-cells this string would need. Correctly

875
876 $term->scr_xor_span ($beg_row, $beg_col, $end_row, $end_col[, $rstyle])
877 XORs the rendition values in the given span with the provided value
878 (default: "RS_RVid"), which *MUST NOT* contain font styles. Useful
879 in refresh hooks to provide effects similar to the selection.
880
881 $term->scr_xor_rect ($beg_row, $beg_col, $end_row, $end_col[, $rstyle1[,
882 $rstyle2]])
883 Similar to "scr_xor_span", but xors a rectangle instead. Trailing
884 whitespace will additionally be xored with the $rstyle2, which
885 defaults to "RS_RVid | RS_Uline", which removes reverse video again
886 and underlines it instead. Both styles *MUST NOT* contain font
887 styles.
888
889 $term->scr_bell
890 Ring the bell!
891
892 $term->scr_add_lines ($string)
893 Write the given text string to the screen, as if output by the
894 application running inside the terminal. It may not contain command
895 sequences (escape codes), but is free to use line feeds, carriage
896 returns and tabs. The string is a normal text string, not in
897 locale-dependent encoding.
898
899 Normally its not a good idea to use this function, as programs might
900 be confused by changes in cursor position or scrolling. Its useful
901 inside a "on_add_lines" hook, though.
902
903 $term->scr_change_screen ($screen)
904 Switch to given screen - 0 primary, 1 secondary.
905
906 $term->cmd_parse ($octets)
907 Similar to "scr_add_lines", but the argument must be in the
908 locale-specific encoding of the terminal and can contain command
909 sequences (escape codes) that will be interpreted.
337 910
338 $term->tt_write ($octets) 911 $term->tt_write ($octets)
339 Write the octets given in $data to the tty (i.e. as program input). 912 Write the octets given in $data to the tty (i.e. as program input).
340 To pass characters instead of octets, you should convert your 913 To pass characters instead of octets, you should convert your
341 strings first to the locale-specific encoding using 914 strings first to the locale-specific encoding using
342 "$term->locale_encode". 915 "$term->locale_encode".
