48		56
49	It also offers the following bindable event:	57	A double-click usually selects the word under the cursor, further clicks
		58	will enlarge the selection.
		59
		60	The selection works by trying to match a number of regexes and displaying
		61	them in increasing order of length. You can add your own regexes by
		62	specifying resources of the form:
		63
		64	URxvt.selection.pattern-0: perl-regex
		65	URxvt.selection.pattern-1: perl-regex
		66	...
		67
		68	The index number (0, 1...) must not have any holes, and each regex must
		69	contain at least one pair of capturing parentheses, which will be used for
		70	the match. For example, the following adds a regex that matches everything
		71	between two vertical bars:
		72
		73	URxvt.selection.pattern-0: \\|([^|]+)\\|
		74
		75	Another example: Programs I use often output "absolute path: " at the
		76	beginning of a line when they process multiple files. The following
		77	pattern matches the filename (note, there is a single space at the very
		78	end):
		79
		80	URxvt.selection.pattern-0: ^(/[^:]+):\
		81
		82	You can look at the source of the selection extension to see more
		83	interesting uses, such as parsing a line from beginning to end.
		84
		85	This extension also offers following bindable keyboard commands:

		97	=item option-popup (enabled by default)
		98
		99	Binds a popup menu to Ctrl-Button2 that lets you toggle (some) options at
		100	runtime.
		101
		102	Other extensions can extend this popup menu by pushing a code reference
		103	onto C<@{ $term->{option_popup_hook} }>, which gets called whenever the
		104	popup is being displayed.
		105
		106	Its sole argument is the popup menu, which can be modified. It should
		107	either return nothing or a string, the initial boolean value and a code
		108	reference. The string will be used as button text and the code reference
		109	will be called when the toggle changes, with the new boolean value as
		110	first argument.
		111
		112	The following will add an entry C<myoption> that changes
		113	C<< $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
		121	Binds a popup menu to Ctrl-Button3 that lets you convert the selection
		122	text into various other formats/action (such as uri unescaping, perl
		123	evaluation, web-browser starting etc.), depending on content.
		124
		125	Other extensions can extend this popup menu by pushing a code reference
		126	onto C<@{ $term->{selection_popup_hook} }>, which gets called whenever the
		127	popup is being displayed.
		128
		129	Its sole argument is the popup menu, which can be modified. The selection
		130	is in C<$_>, which can be used to decide whether to add something or not.
		131	It should either return nothing or a string and a code reference. The
		132	string will be used as button text and the code reference will be called
		133	when the button gets activated and should transform C<$_>.
		134
		135	The following will add an entry C<a to b> that transforms all C<a>s in
		136	the selection to C<b>s, but only if the selection currently contains any
		137	C<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
		146	Adds regex search functionality to the scrollback buffer, triggered
		147	by a hotkey (default: C<M-s>). While in search mode, normal terminal
		148	input/output is suspended and a regex is displayed at the bottom of the
		149	screen.
		150
		151	Inputting characters appends them to the regex and continues incremental
		152	search. C<BackSpace> removes a character from the regex, C<Up> and C<Down>
		153	search upwards/downwards in the scrollback buffer, C<End> jumps to the
		154	bottom. C<Escape> leaves search mode and returns to the point where search
		155	was started, while C<Enter> or C<Return> stay at the current position and
		156	additionally stores the first match in the current line into the primary
		157	selection if the C<Shift> modifier is active.
		158
		159	The regex defaults to "(?i)", resulting in a case-insensitive search. To
		160	get a case-sensitive search you can delete this prefix using C<BackSpace>
		161	or simply use an uppercase character which removes the "(?i)" prefix.
		162
		163	See L<perlre> for more info about perl regular expression syntax.
		164
		165	=item readline (enabled by default)
		166
		167	A support package that tries to make editing with readline easier. At
		168	the moment, it reacts to clicking shift-left mouse button by trying to
		169	move the text cursor to this position. It does so by generating as many
		170	cursor-left or cursor-right keypresses as required (this only works
		171	for programs that correctly support wide characters).
		172
		173	To 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
		187	The normal selection mechanism isn't disabled, so quick successive clicks
		188	might interfere with selection creation in harmless ways.
		189
		190	=item selection-autotransform
		191
		192	This selection allows you to do automatic transforms on a selection
		193	whenever a selection is made.
		194
		195	It works by specifying perl snippets (most useful is a single C<s///>
		196	operator) that modify C<$_> as resources:
		197
		198	URxvt.selection-autotransform.0: transform
		199	URxvt.selection-autotransform.1: transform
		200	...
		201
		202	For example, the following will transform selections of the form
		203	C<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$1\\E\\x0d/
		207
		208	And this example matches the same,but replaces it with vi-commands you can
		209	paste directly into your (vi :) editor:
		210
		211	URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/
		212
		213	Of course, this can be modified to suit your needs and your editor :)
		214
		215	To expand the example above to typical perl error messages ("XXX at
		216	FILENAME line YYY."), you need a slightly more elaborate solution:
		217
		218	URxvt.selection.pattern-0: ( at .*? line \\d+[,.])
		219	URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/
		220
		221	The first line tells the selection code to treat the unchanging part of
		222	every error message as a selection pattern, and the second line transforms
		223	the message into vi commands to load the file.
		224
		225	=item tabbed
		226
		227	This transforms the terminal into a tabbar with additional terminals, that
		228	is, it implements what is commonly referred to as "tabbed terminal". The topmost line
		229	displays a "[NEW]" button, which, when clicked, will add a new tab, followed by one
		230	button per tab.
		231
		232	Clicking a button will activate that tab. Pressing B<Shift-Left> and
		233	B<Shift-Right> will switch to the tab left or right of the current one,
		234	while B<Shift-Down> creates a new tab.
		235
		236	The tabbar itself can be configured similarly to a normal terminal, but
		237	with a resource class of C<URxvt.tabbed>. In addition, it supports the
		238	following 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
		245	See I<COLOR AND GRAPHICS> in the @@RXVT_NAME@@(1) manpage for valid
		246	indices.
		247
		248	=item matcher
		249
		250	Uses per-line display filtering (C<on_line_update>) to underline text
		251	matching a certain pattern and make it clickable. When clicked with the
		252	mouse button specified in the C<matcher.button> resource (default 2, or
		253	middle), the program specified in the C<matcher.launcher> resource
		254	(default, the C<urlLauncher> resource, C<sensible-browser>) will be started
		255	with the matched text as first argument. The default configuration is
		256	suitable for matching URLs and launching a web browser, like the
		257	former "mark-urls" extension.
		258
		259	The default pattern to match URLs can be overridden with the
		260	C<matcher.pattern.0> resource, and additional patterns can be specified
		261	with numbered patterns, in a manner similar to the "selection" extension.
		262	The launcher can also be overridden on a per-pattern basis.
		263
		264	It is possible to activate the most recently seen match or a list of matches
		265	from the keyboard. Simply bind a keysym to "perl:matcher:last" or
		266	"perl:matcher:list" as seen in the example below.
		267
		268	Example 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
		281	This (experimental) perl extension implements OnTheSpot editing. It does
		282	not work perfectly, and some input methods don't seem to work well with
		283	OnTheSpot editing in general, but it seems to work at least for SCIM and
		284	kinput2.
		285
		286	You enable it by specifying this extension and a preedit style of
		287	C<OnTheSpot>, i.e.:
		288
		289	@@RXVT_NAME@@ -pt OnTheSpot -pe xim-onthespot
		290
		291	=item kuake<hotkey>
		292
		293	A very primitive quake-console-like extension. It was inspired by a
		294	description of how the programs C<kuake> and C<yakuake> work: Whenever the
		295	user presses a global accelerator key (by default C<F10>), the terminal
		296	will show or hide itself. Another press of the accelerator key will hide
		297	or show it again.
		298
		299	Initially, the window will not be shown when using this extension.
		300
		301	This is useful if you need a single terminal that is not using any desktop
		302	space most of the time but is quickly available at the press of a key.
		303
		304	The accelerator key is grabbed regardless of any modifiers, so this
		305	extension will actually grab a physical key just for this function.
		306
		307	If you want a quake-like animation, tell your window manager to do so
		308	(fvwm can do it).
		309
		310	=item overlay-osc
		311
		312	This extension implements some OSC commands to display timed popups on the
		313	screen - useful for status displays from within scripts. You have to read
		314	the sources for more info.
		315
		316	=item block-graphics-to-ascii
		317
		318	A not very useful example of filtering all text output to the terminal
		319	by replacing all line-drawing characters (U+2500 .. U+259F) by a
		320	similar-looking ascii character.
		321
61	=item digital-clock	322	=item digital-clock
62		323
63	Displays a digital clock using the built-in overlay.	324	Displays a digital clock using the built-in overlay.
		325
		326	=item remote-clipboard
		327
		328	Somewhat of a misnomer, this extension adds two menu entries to the
		329	selection popup that allows one to run external commands to store the
		330	selection somewhere and fetch it again.
		331
		332	We use it to implement a "distributed selection mechanism", which just
		333	means that one command uploads the file to a remote server, and another
		334	reads it.
		335
		336	The commands can be set using the C<URxvt.remote-selection.store> and
		337	C<URxvt.remote-selection.fetch> resources. The first should read the
		338	selection to store from STDIN (always in UTF-8), the second should provide
		339	the selection data on STDOUT (also in UTF-8).
		340
		341	The 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
		348	This is a little rarely useful extension that uploads the selection as
		349	textfile to a remote site (or does other things). (The implementation is
		350	not currently secure for use in a multiuser environment as it writes to
		351	F</tmp> directly.).
		352
		353	It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
		354	i.e.
		355
		356	URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
		357
		358	Pressing this combination runs a command with C<%> replaced by the name of
		359	the 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
		363	And the default is likely not useful to anybody but the few people around
		364	here :)
		365
		366	The name of the textfile is the hex encoded md5 sum of the selection, so
		367	the same content should lead to the same filename.
		368
		369	After a successful upload the selection will be replaced by the text given
		370	in the C<selection-pastebin-url> resource (again, the % is the placeholder
		371	for the filename):
		372
		373	URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/%
		374
		375	I<Note to xrdb users:> xrdb uses the C preprocessor, which might interpret
		376	the double C</> characters as comment start. Use C<\057\057> instead,
		377	which works regardless of whether xrdb is used to parse the resource file
		378	or not.
		379
		380	=item macosx-clipboard and macosx-clipboard-native
		381
		382	These two modules implement an extended clipboard for Mac OS X. They are
		383	used 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
		389	The difference between them is that the native variant requires a
		390	perl from apple's devkit or so, and C<macosx-clipboard> requires the
		391	C<Mac::Pasteboard> module, works with other perls, has fewer bugs, is
		392	simpler etc. etc.

		422	Argument names also often indicate the type of a parameter. Here are some
		423	hints on what they mean:
		424
		425	=over 4
		426
		427	=item $text
		428
		429	Rxvt-unicode's special way of encoding text, where one "unicode" character
		430	always represents one screen cell. See L<ROW_t> for a discussion of this format.
		431
		432	=item $string
		433
		434	A perl text string, with an emphasis on I<text>. It can store all unicode
		435	characters and is to be distinguished with text encoded in a specific
		436	encoding (often locale-specific) and binary data.
		437
		438	=item $octets
		439
		440	Either binary data or - more common - a text string encoded in a
		441	locale-specific way.
		442
		443	=back
		444
		445	=head2 Extension Objects
		446
		447	Every perl extension is a perl class. A separate perl object is created
		448	for each terminal, and each terminal has its own set of extension objects,
		449	which are passed as the first parameter to hooks. So extensions can use
		450	their C<$self> object without having to think about clashes with other
		451	extensions or other terminals, with the exception of methods and members
		452	that begin with an underscore character C<_>: these are reserved for
		453	internal use.
		454
		455	Although it isn't a C<urxvt::term> object, you can call all methods of the
		456	C<urxvt::term> class on this object.
		457
		458	It has the following methods and data members:
		459
		460	=over 4
		461
		462	=item $urxvt_term = $self->{term}
		463
		464	Returns the C<urxvt::term> object associated with this instance of the
		465	extension. This member I<must not> be changed in any way.
		466
		467	=item $self->enable ($hook_name => $cb, [$hook_name => $cb..])
		468
		469	Dynamically enable the given hooks (named without the C<on_> prefix) for
		470	this extension, replacing any previous hook. This is useful when you want
		471	to overwrite time-critical hooks only temporarily.
		472
		473	=item $self->disable ($hook_name[, $hook_name..])
		474
		475	Dynamically disable the given hooks.

		576	behaviour. The default should be to return an empty list. A true value
		577	suppresses execution of the request completely. Make sure you don't get
		578	confused by recursive invocations when you output an OSC sequence within

		582
		583	=item on_osc_seq_perl $term, $args, $resp
		584
		585	Called whenever the B<ESC ] 777 ; string ST> command sequence (OSC =
		586	operating system command) is processed. Cursor position and other state
		587	information is up-to-date when this happens. For interoperability, the
		588	string should start with the extension name (sans -osc) and a semicolon,
		589	to distinguish it from commands for other extensions, and this might be
		590	enforced in the future.
		591
		592	For example, C<overlay-osc> uses this:

		600	}
		601
		602	Be careful not ever to trust (in a security sense) the data you receive,
		603	as its source can not easily be controlled (e-mail content, messages from
		604	other users on the same system etc.).
		605
		606	For responses, C<$resp> contains the end-of-args separator used by the
		607	sender.
		608
		609	=item on_add_lines $term, $string
		610
		611	Called whenever text is about to be output, with the text as argument. You
		612	can filter/change and output the text yourself by returning a true value
		613	and calling C<< $term->scr_add_lines >> yourself. Please note that this

		615	output.
		616
		617	=item on_tt_write $term, $octets

		620	suppress or filter tty input.
		621
		622	=item on_tt_paste $term, $octets
		623
		624	Called whenever text is about to be pasted, with the text as argument. You
		625	can filter/change and paste the text yourself by returning a true value
		626	and calling C<< $term->tt_paste >> yourself. C<$octets> is
		627	locale-encoded.
		628
		629	=item on_line_update $term, $row
		630
		631	Called whenever a line was updated or changed. Can be used to filter
		632	screen output (e.g. underline urls or other useless stuff). Only lines
		633	that are being shown will be filtered, and, due to performance reasons,
		634	not always immediately.
		635
		636	The row number is always the topmost row of the line if the line spans
		637	multiple rows.
		638
		639	Please note that, if you change the line, then the hook might get called
		640	later with the already-modified line (e.g. if unrelated parts change), so
		641	you cannot just toggle rendition bits, but only set them.
