40=over 4 47=over 4
41 48
42=item selection 49=item selection (enabled by default)
43 50
44Miscellaneous selection modifications. 51(More) intelligent selection. This extension tries to be more intelligent
52when the user extends selections (double-click and further clicks). Right
53now, it tries to select words, urls and complete shell-quoted
54arguments, which is very convenient, too, if your F<ls> supports
55C<--quoting-style=shell>.
56
57A double-click usually selects the word under the cursor, further clicks
58will enlarge the selection.
59
60The selection works by trying to match a number of regexes and displaying
61them in increasing order of length. You can add your own regexes by
62specifying resources of the form:
63
64 URxvt.selection.pattern-0: perl-regex
65 URxvt.selection.pattern-1: perl-regex
66 ...
67
68The index number (0, 1...) must not have any holes, and each regex must
69contain at least one pair of capturing parentheses, which will be used for
70the match. For example, the following adds a regex that matches everything
71between two vertical bars:
72
73 URxvt.selection.pattern-0: \\|([^|]+)\\|
74
75Another example: Programs I use often output "absolute path: " at the
76beginning of a line when they process multiple files. The following
77pattern matches the filename (note, there is a single space at the very
78end):
79
80 URxvt.selection.pattern-0: ^(/[^:]+):\
81
82You can look at the source of the selection extension to see more
83interesting uses, such as parsing a line from beginning to end.
84
85This extension also offers following bindable keyboard commands:

54=back 95=back
55 96
97=item option-popup (enabled by default)
98
99Binds a popup menu to Ctrl-Button2 that lets you toggle (some) options at
100runtime.
101
102Other extensions can extend this popup menu by pushing a code reference
103onto C<@{ $term->{option_popup_hook} }>, which gets called whenever the
104popup is being displayed.
105
106Its sole argument is the popup menu, which can be modified. It should
107either return nothing or a string, the initial boolean value and a code
108reference. The string will be used as button text and the code reference
109will be called when the toggle changes, with the new boolean value as
110first argument.
111
112The following will add an entry C<myoption> that changes
113C<< $self->{myoption} >>:
114
115 push @{ $self->{term}{option_popup_hook} }, sub {
116 ("my option" => $myoption, sub { $self->{myoption} = $_[0] })
117 };
118
119=item selection-popup (enabled by default)
120
121Binds a popup menu to Ctrl-Button3 that lets you convert the selection
122text into various other formats/action (such as uri unescaping, perl
123evaluation, web-browser starting etc.), depending on content.
124
125Other extensions can extend this popup menu by pushing a code reference
126onto C<@{ $term->{selection_popup_hook} }>, which gets called whenever the
127popup is being displayed.
128
129Its sole argument is the popup menu, which can be modified. The selection
130is in C<$_>, which can be used to decide whether to add something or not.
131It should either return nothing or a string and a code reference. The
132string will be used as button text and the code reference will be called
133when the button gets activated and should transform C<$_>.
134
135The following will add an entry C<a to b> that transforms all C<a>s in
136the selection to C<b>s, but only if the selection currently contains any
137C<a>s:
138
139 push @{ $self->{term}{selection_popup_hook} }, sub {
140 /a/ ? ("a to b" => sub { s/a/b/g }
141 : ()
142 };
143
144=item searchable-scrollback<hotkey> (enabled by default)
145
146Adds regex search functionality to the scrollback buffer, triggered
147by a hotkey (default: C<M-s>). While in search mode, normal terminal
148input/output is suspended and a regex is displayed at the bottom of the
149screen.
150
151Inputting characters appends them to the regex and continues incremental
152search. C<BackSpace> removes a character from the regex, C<Up> and C<Down>
153search upwards/downwards in the scrollback buffer, C<End> jumps to the
154bottom. C<Escape> leaves search mode and returns to the point where search
155was started, while C<Enter> or C<Return> stay at the current position and
156additionally stores the first match in the current line into the primary
157selection if the C<Shift> modifier is active.
158
159The regex defaults to "(?i)", resulting in a case-insensitive search. To
160get a case-sensitive search you can delete this prefix using C<BackSpace>
161or simply use an uppercase character which removes the "(?i)" prefix.
162
163See L<perlre> for more info about perl regular expression syntax.
164
165=item readline (enabled by default)
166
167A support package that tries to make editing with readline easier. At
168the moment, it reacts to clicking shift-left mouse button by trying to
169move the text cursor to this position. It does so by generating as many
170cursor-left or cursor-right keypresses as required (this only works
171for programs that correctly support wide characters).
172
173To avoid too many false positives, this is only done when:
174
175=over 4
176
177=item - the tty is in ICANON state.
178
179=item - the text cursor is visible.
180
181=item - the primary screen is currently being displayed.
182
183=item - the mouse is on the same (multi-row-) line as the text cursor.
184
185=back
186
187The normal selection mechanism isn't disabled, so quick successive clicks
188might interfere with selection creation in harmless ways.
189
190=item selection-autotransform
191
192This selection allows you to do automatic transforms on a selection
193whenever a selection is made.
194
195It works by specifying perl snippets (most useful is a single C<s///>
196operator) that modify C<$_> as resources:
197
198 URxvt.selection-autotransform.0: transform
199 URxvt.selection-autotransform.1: transform
200 ...
201
202For example, the following will transform selections of the form
203C<filename:number>, often seen in compiler messages, into C<vi +$filename
204$word>:
205
206 URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/
207
208And this example matches the same,but replaces it with vi-commands you can
209paste directly into your (vi :) editor:
210
211 URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/
212
213Of course, this can be modified to suit your needs and your editor :)
214
215To expand the example above to typical perl error messages ("XXX at
216FILENAME line YYY."), you need a slightly more elaborate solution:
217
218 URxvt.selection.pattern-0: ( at .*? line \\d+[,.])
219 URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/
220
221The first line tells the selection code to treat the unchanging part of
222every error message as a selection pattern, and the second line transforms
223the message into vi commands to load the file.
224
225=item tabbed
226
227This transforms the terminal into a tabbar with additional terminals, that
228is, it implements what is commonly referred to as "tabbed terminal". The topmost line
229displays a "[NEW]" button, which, when clicked, will add a new tab, followed by one
230button per tab.
231
232Clicking a button will activate that tab. Pressing B<Shift-Left> and
233B<Shift-Right> will switch to the tab left or right of the current one,
234while B<Shift-Down> creates a new tab.
235
236The tabbar itself can be configured similarly to a normal terminal, but
237with a resource class of C<URxvt.tabbed>. In addition, it supports the
238following four resources (shown with defaults):
239
240 URxvt.tabbed.tabbar-fg: <colour-index, default 3>
241 URxvt.tabbed.tabbar-bg: <colour-index, default 0>
242 URxvt.tabbed.tab-fg: <colour-index, default 0>
243 URxvt.tabbed.tab-bg: <colour-index, default 1>
244
245See I<COLOR AND GRAPHICS> in the @@RXVT_NAME@@(1) manpage for valid
246indices.
247
248=item matcher
249
250Uses per-line display filtering (C<on_line_update>) to underline text
251matching a certain pattern and make it clickable. When clicked with the
252mouse button specified in the C<matcher.button> resource (default 2, or
253middle), the program specified in the C<matcher.launcher> resource
254(default, the C<urlLauncher> resource, C<sensible-browser>) will be started
255with the matched text as first argument. The default configuration is
256suitable for matching URLs and launching a web browser, like the
257former "mark-urls" extension.
258
259The default pattern to match URLs can be overridden with the
260C<matcher.pattern.0> resource, and additional patterns can be specified
261with numbered patterns, in a manner similar to the "selection" extension.
262The launcher can also be overridden on a per-pattern basis.
263
264It is possible to activate the most recently seen match or a list of matches
265from the keyboard. Simply bind a keysym to "perl:matcher:last" or
266"perl:matcher:list" as seen in the example below.
267
268Example configuration:
269
270 URxvt.perl-ext: default,matcher
271 URxvt.urlLauncher: sensible-browser
272 URxvt.keysym.C-Delete: perl:matcher:last
273 URxvt.keysym.M-Delete: perl:matcher:list
274 URxvt.matcher.button: 1
275 URxvt.matcher.pattern.1: \\bwww\\.[\\w-]+\\.[\\w./?&@#-]*[\\w/-]
276 URxvt.matcher.pattern.2: \\B(/\\S+?):(\\d+)(?=:|$)
277 URxvt.matcher.launcher.2: gvim +$2 $1
278
279=item xim-onthespot
280
281This (experimental) perl extension implements OnTheSpot editing. It does
282not work perfectly, and some input methods don't seem to work well with
283OnTheSpot editing in general, but it seems to work at least for SCIM and
284kinput2.
285
286You enable it by specifying this extension and a preedit style of
287C<OnTheSpot>, i.e.:
288
289 @@RXVT_NAME@@ -pt OnTheSpot -pe xim-onthespot
290
291=item kuake<hotkey>
292
293A very primitive quake-console-like extension. It was inspired by a
294description of how the programs C<kuake> and C<yakuake> work: Whenever the
295user presses a global accelerator key (by default C<F10>), the terminal
296will show or hide itself. Another press of the accelerator key will hide
297or show it again.
298
299Initially, the window will not be shown when using this extension.
300
301This is useful if you need a single terminal that is not using any desktop
302space most of the time but is quickly available at the press of a key.
303
304The accelerator key is grabbed regardless of any modifiers, so this
305extension will actually grab a physical key just for this function.
306
307If you want a quake-like animation, tell your window manager to do so
308(fvwm can do it).
309
310=item overlay-osc
311
312This extension implements some OSC commands to display timed popups on the
313screen - useful for status displays from within scripts. You have to read
314the sources for more info.
315
316=item block-graphics-to-ascii
317
318A not very useful example of filtering all text output to the terminal
319by replacing all line-drawing characters (U+2500 .. U+259F) by a
320similar-looking ascii character.
321
56=item digital-clock 322=item digital-clock
323
324Displays a digital clock using the built-in overlay.
325
326=item remote-clipboard
327
328Somewhat of a misnomer, this extension adds two menu entries to the
329selection popup that allows one to run external commands to store the
330selection somewhere and fetch it again.
331
332We use it to implement a "distributed selection mechanism", which just
333means that one command uploads the file to a remote server, and another
334reads it.
335
336The commands can be set using the C<URxvt.remote-selection.store> and
337C<URxvt.remote-selection.fetch> resources. The first should read the
338selection to store from STDIN (always in UTF-8), the second should provide
339the selection data on STDOUT (also in UTF-8).
340
341The defaults (which are likely useless to you) use rsh and cat:
342
343 URxvt.remote-selection.store: rsh ruth 'cat >/tmp/distributed-selection'
344 URxvt.remote-selection.fetch: rsh ruth 'cat /tmp/distributed-selection'
345
346=item selection-pastebin
347
348This is a little rarely useful extension that uploads the selection as
349textfile to a remote site (or does other things). (The implementation is
350not currently secure for use in a multiuser environment as it writes to
351F</tmp> directly.).
352
353It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
354i.e.
355
356 URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
357
358Pressing this combination runs a command with C<%> replaced by the name of
359the textfile. This command can be set via a resource:
360
361 URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
362
363And the default is likely not useful to anybody but the few people around
364here :)
365
366The name of the textfile is the hex encoded md5 sum of the selection, so
367the same content should lead to the same filename.
368
369After a successful upload the selection will be replaced by the text given
370in the C<selection-pastebin-url> resource (again, the % is the placeholder
371for the filename):
372
373 URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/%
374
375I<Note to xrdb users:> xrdb uses the C preprocessor, which might interpret
376the double C</> characters as comment start. Use C<\057\057> instead,
377which works regardless of whether xrdb is used to parse the resource file
378or not.
379
380=item macosx-clipboard and macosx-clipboard-native
381
382These two modules implement an extended clipboard for Mac OS X. They are
383used like this:
384
385 URxvt.perl-ext-common: default,macosx-clipboard
386 URxvt.keysym.M-c: perl:macosx-clipboard:copy
387 URxvt.keysym.M-v: perl:macosx-clipboard:paste
388
389The difference between them is that the native variant requires a
390perl from apple's devkit or so, and C<macosx-clipboard> requires the
391C<Mac::Pasteboard> module, works with other perls, has fewer bugs, is
392simpler etc. etc.

404
405=item bell-command
406
407Runs the command specified by the C<URxvt.bell-command> resource when
408a bell event occurs. For example, the following pops up a notification
409bubble with the text "Beep, Beep" using notify-send:

430Argument names also often indicate the type of a parameter. Here are some
431hints on what they mean:
432
433=over 4
434
435=item $text
436
437Rxvt-unicode's special way of encoding text, where one "unicode" character
438always represents one screen cell. See L<ROW_t> for a discussion of this format.
439
440=item $string
441
442A perl text string, with an emphasis on I<text>. It can store all unicode
443characters and is to be distinguished with text encoded in a specific
444encoding (often locale-specific) and binary data.
445
446=item $octets
447
448Either binary data or - more common - a text string encoded in a
449locale-specific way.
450
451=item $keysym
452
453an integer that is a valid X11 keysym code. You can convert a string
454into a keysym and viceversa by using C<XStringToKeysym> and
455C<XKeysymToString>.
456
457=back
458
459=head2 Extension Objects
460
461Every perl extension is a perl class. A separate perl object is created
462for each terminal, and each terminal has its own set of extension objects,
463which are passed as the first parameter to hooks. So extensions can use
464their C<$self> object without having to think about clashes with other
465extensions or other terminals, with the exception of methods and members
466that begin with an underscore character C<_>: these are reserved for
467internal use.
468
469Although it isn't a C<urxvt::term> object, you can call all methods of the
470C<urxvt::term> class on this object.
471
472It has the following methods and data members:
473
474=over 4
475
476=item $urxvt_term = $self->{term}
477
478Returns the C<urxvt::term> object associated with this instance of the
479extension. This member I<must not> be changed in any way.
480
481=item $self->enable ($hook_name => $cb, [$hook_name => $cb..])
482
483Dynamically enable the given hooks (named without the C<on_> prefix) for
484this extension, replacing any previous hook. This is useful when you want
485to overwrite time-critical hooks only temporarily.
486

129Called whenever the window gets the keyboard focus, before urxvt does 562Called whenever the user tries to extend the selection (e.g. with a double
130focus in processing. 563click) and is either supposed to return false (normal operation), or
564should extend the selection itself and return true to suppress the built-in
565processing. This can happen multiple times, as long as the callback
566returns true, it will be called on every further click by the user and is
567supposed to enlarge the selection more and more, if possible.
131 568
132=item on_focus_out $term 569See the F<selection> example extension.

152 586
153=item on_tty_activity $term *NYI* 587=item on_osc_seq $term, $op, $args, $resp
154 588
155Called whenever the program(s) running in the urxvt window send output. 589Called on every OSC sequence and can be used to suppress it or modify its
590behaviour. The default should be to return an empty list. A true value
591suppresses execution of the request completely. Make sure you don't get
592confused by recursive invocations when you output an OSC sequence within
593this callback.
594
595C<on_osc_seq_perl> should be used for new behaviour.
596
597=item on_osc_seq_perl $term, $args, $resp
598
599Called whenever the B<ESC ] 777 ; string ST> command sequence (OSC =
600operating system command) is processed. Cursor position and other state
601information is up-to-date when this happens. For interoperability, the
602string should start with the extension name (sans -osc) and a semicolon,
603to distinguish it from commands for other extensions, and this might be
604enforced in the future.
605
606For example, C<overlay-osc> uses this:
607
608 sub on_osc_seq_perl {
609 my ($self, $osc, $resp) = @_;
610
611 return unless $osc =~ s/^overlay;//;
612
613 ... process remaining $osc string
614 }
615
616Be careful not ever to trust (in a security sense) the data you receive,
617as its source can not easily be controlled (e-mail content, messages from
618other users on the same system etc.).
619
620For responses, C<$resp> contains the end-of-args separator used by the
621sender.
622
623=item on_add_lines $term, $string
624
625Called whenever text is about to be output, with the text as argument. You
626can filter/change and output the text yourself by returning a true value
627and calling C<< $term->scr_add_lines >> yourself. Please note that this
628might be very slow, however, as your hook is called for B<all> text being
629output.
630
631=item on_tt_write $term, $octets
632
633Called whenever some data is written to the tty/pty and can be used to
634suppress or filter tty input.
635
636=item on_tt_paste $term, $octets
637
638Called whenever text is about to be pasted, with the text as argument. You
639can filter/change and paste the text yourself by returning a true value
640and calling C<< $term->tt_paste >> yourself. C<$octets> is
641locale-encoded.
642
643=item on_line_update $term, $row
644
645Called whenever a line was updated or changed. Can be used to filter
646screen output (e.g. underline urls or other useless stuff). Only lines
647that are being shown will be filtered, and, due to performance reasons,
648not always immediately.
649
650The row number is always the topmost row of the line if the line spans
651multiple rows.
652
653Please note that, if you change the line, then the hook might get called
654later with the already-modified line (e.g. if unrelated parts change), so
655you cannot just toggle rendition bits, but only set them.
156 656
157=item on_refresh_begin $term 657=item on_refresh_begin $term
158 658
159Called just before the screen gets redrawn. Can be used for overlay 659Called just before the screen gets redrawn. Can be used for overlay or
160or similar effects by modify terminal contents in refresh_begin, and 660similar effects by modifying the terminal contents in refresh_begin, and
161restoring them in refresh_end. The built-in overlay and selection display 661restoring them in refresh_end. The built-in overlay and selection display
162code is run after this hook, and takes precedence. 662code is run after this hook, and takes precedence.

167 667
168=item on_keyboard_command $term, $string 668=item on_user_command $term, $string
169 669
170Called whenever the user presses a key combination that has a 670Called whenever a user-configured event is being activated (e.g. via
171C<perl:string> action bound to it (see description of the B<keysym> 671a C<perl:string> action bound to a key, see description of the B<keysym>
172resource in the @@RXVT_NAME@@(1) manpage). 672resource in the @@RXVT_NAME@@(1) manpage).
173 673
674The event is simply the action string. This interface is assumed to change
675slightly in the future.
676
677=item on_register_command $term, $keysym, $modifiermask, $string
678
679Called after parsing a keysym resource but before registering the
680associated binding. If this hook returns TRUE the binding is not
681registered. It can be used to modify a binding by calling
682C<register_command>.
683
684=item on_resize_all_windows $term, $new_width, $new_height
685
686Called just after the new window size has been calculated, but before
687windows are actually being resized or hints are being set. If this hook
688returns TRUE, setting of the window hints is being skipped.
689
690=item on_x_event $term, $event
691
692Called on every X event received on the vt window (and possibly other
693windows). Should only be used as a last resort. Most event structure
694members are not passed.
695
696=item on_root_event $term, $event

698Like C<on_x_event>, but is called for events on the root window.
699
700=item on_focus_in $term
701
702Called whenever the window gets the keyboard focus, before rxvt-unicode
703does focus in processing.
704
705=item on_focus_out $term
706
707Called whenever the window loses keyboard focus, before rxvt-unicode does
708focus out processing.

725
726=item on_unmap_notify $term, $event
727
728Called whenever the corresponding X event is received for the terminal. If
729the hook returns true, then the event will be ignored by rxvt-unicode.
730
731The event is a hash with most values as named by Xlib (see the XEvent
732manpage), with the additional members C<row> and C<col>, which are the
733(real, not screen-based) row and column under the mouse cursor.
734
735C<on_key_press> additionally receives the string rxvt-unicode would
736output, if any, in locale-specific encoding.

1185further programming. The only exception is that you cannot wait on
1186condition variables, but non-blocking condvar use is ok. What this means
1187is that you cannot use blocking APIs, but the non-blocking variant should

1297
1298Creates a new terminal, very similar as if you had started it with system
1299C<$rxvtname, arg...>. C<$envhashref> must be a reference to a C<%ENV>-like
1300hash which defines the environment of the new terminal.
1301
1302Croaks (and probably outputs an error message) if the new instance
1303couldn't be created. Returns C<undef> if the new instance didn't
1304initialise perl, and the terminal object otherwise. The C<init> and
1305C<start> hooks will be called before this call returns, and are free to
1306refer to global data (which is race free).

1329the user environment before exec'ing the command (e.g. C<PATH>) and should
1330be preferred over explicit calls to C<exec> or C<system>.

1417
1418This method should only be called during the C<on_start> hook, as there is

1430C<parse_keysym>, as it expects a parsed key description, and can be
1431used only inside either the C<on_init> hook, to add a binding, or the

1452When arguments are given, then the selection coordinates are set to
1453C<$row> and C<$col>, and the selection screen is set to the current
1454screen.

1457
1458Returns the current selection screen, and then optionally sets it.

1460=item $term->selection_make ($eventtime[, $rectangular])
1461
1462Tries to make a selection as set by C<selection_beg> and
1463C<selection_end>. If C<$rectangular> is true (default: false), a
1464rectangular selection will be made. This is the preferred function to make

1936
1937Calls XGrabPointer and XGrabKeyboard in asynchronous (default) or
1938synchronous (C<$sync> is true). Also remembers the grab timestamp.
1939
1940=item $term->allow_events_async
1941
1942Calls XAllowEvents with AsyncBoth for the most recent grab.
1943
1944=item $term->allow_events_sync
1945
1946Calls XAllowEvents with SyncBoth for the most recent grab.
1947
1948=item $term->allow_events_replay
1949
1950Calls XAllowEvents with both ReplayPointer and ReplayKeyboard for the most
1951recent grab.
1952
1953=item $term->ungrab
1954
1955Calls XUngrabPointer and XUngrabKeyboard for the most recent grab. Is called automatically on
1956evaluation errors, as it is better to lose the grab in the error case as
1957the session.
