48		53
49	It also offers the following bindable event:	54	A double-click usually selects the word under the cursor, further clicks
		55	will enlarge the selection.
		56
		57	The selection works by trying to match a number of regexes and displaying
		58	them in increasing order of length. You can add your own regexes by
		59	specifying resources of the form:
		60
		61	URxvt.selection.pattern-0: perl-regex
		62	URxvt.selection.pattern-1: perl-regex
		63	...
		64
		65	The index number (0, 1...) must not have any holes, and each regex must
		66	contain at least one pair of capturing parentheses, which will be used for
		67	the match. For example, the following adds a regex that matches everything
		68	between two vertical bars:
		69
		70	URxvt.selection.pattern-0: \\|([^|]+)\\|
		71
		72	Another example: Programs I use often output "absolute path: " at the
		73	beginning of a line when they process multiple files. The following
		74	pattern matches the filename (note, there is a single space at the very
		75	end):
		76
		77	URxvt.selection.pattern-0: ^(/[^:]+):\
		78
		79	You can look at the source of the selection extension to see more
		80	interesting uses, such as parsing a line from beginning to end.
		81
		82	This extension also offers following bindable keyboard commands:

		154	selection.

81	Displays a digital clock using the built-in overlay.	156	The regex defaults to "(?i)", resulting in a case-insensitive search. To
		157	get a case-sensitive search you can delete this prefix using C<BackSpace>
		158	or simply use an uppercase character which removes the "(?i)" prefix.
82		159
83	=item mark-urls	160	See L<perlre> for more info about perl regular expression syntax.
84		161
		162	=item readline (enabled by default)
		163
		164	A support package that tries to make editing with readline easier. At
		165	the moment, it reacts to clicking shift-left mouse button by trying to
		166	move the text cursor to this position. It does so by generating as many
		167	cursor-left or cursor-right keypresses as required (the this only works
		168	for programs that correctly support wide characters).
		169
		170	To avoid too many false positives, this is only done when:
		171
		172	=over 4
		173
		174	=item - the tty is in ICANON state.
		175
		176	=item - the text cursor is visible.
		177
		178	=item - the primary screen is currently being displayed.
		179
		180	=item - the mouse is on the same (multi-row-) line as the text cursor.
		181
		182	=back
		183
		184	The normal selection mechanism isn't disabled, so quick successive clicks
		185	might interfere with selection creation in harmless ways.
		186
		187	=item selection-autotransform
		188
		189	This selection allows you to do automatic transforms on a selection
		190	whenever a selection is made.
		191
		192	It works by specifying perl snippets (most useful is a single C<s///>
		193	operator) that modify C<$_> as resources:
		194
		195	URxvt.selection-autotransform.0: transform
		196	URxvt.selection-autotransform.1: transform
		197	...
		198
		199	For example, the following will transform selections of the form
		200	C<filename:number>, often seen in compiler messages, into C<vi +$filename
		201	$word>:
		202
		203	URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/
		204
		205	And this example matches the same,but replaces it with vi-commands you can
		206	paste directly into your (vi :) editor:
		207
		208	URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/
		209
		210	Of course, this can be modified to suit your needs and your editor :)
		211
		212	To expand the example above to typical perl error messages ("XXX at
		213	FILENAME line YYY."), you need a slightly more elaborate solution:
		214
		215	URxvt.selection.pattern-0: ( at .*? line \\d+[,.])
		216	URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/
		217
		218	The first line tells the selection code to treat the unchanging part of
		219	every error message as a selection pattern, and the second line transforms
		220	the message into vi commands to load the file.
		221
		222	=item tabbed
		223
		224	This transforms the terminal into a tabbar with additional terminals, that
		225	is, it implements what is commonly referred to as "tabbed terminal". The topmost line
		226	displays a "[NEW]" button, which, when clicked, will add a new tab, followed by one
		227	button per tab.
		228
		229	Clicking a button will activate that tab. Pressing B<Shift-Left> and
		230	B<Shift-Right> will switch to the tab left or right of the current one,
		231	while B<Shift-Down> creates a new tab.
		232
		233	The tabbar itself can be configured similarly to a normal terminal, but
		234	with a resource class of C<URxvt.tabbed>. In addition, it supports the
		235	following four resources (shown with defaults):
		236
		237	URxvt.tabbed.tabbar-fg: <colour-index, default 3>
		238	URxvt.tabbed.tabbar-bg: <colour-index, default 0>
		239	URxvt.tabbed.tab-fg: <colour-index, default 0>
		240	URxvt.tabbed.tab-bg: <colour-index, default 1>
		241
		242	See I<COLOR AND GRAPHICS> in the @@RXVT_NAME@@(1) manpage for valid
		243	indices.
		244
		245	=item matcher
		246
85	Uses per-line display filtering (C<on_line_update>) to underline urls.	247	Uses per-line display filtering (C<on_line_update>) to underline text
		248	matching a certain pattern and make it clickable. When clicked with the
		249	mouse button specified in the C<matcher.button> resource (default 2, or
		250	middle), the program specified in the C<matcher.launcher> resource
		251	(default, the C<urlLauncher> resource, C<sensible-browser>) will be started
		252	with the matched text as first argument. The default configuration is
		253	suitable for matching URLs and launching a web browser, like the
		254	former "mark-urls" extension.
		255
		256	The default pattern to match URLs can be overridden with the
		257	C<matcher.pattern.0> resource, and additional patterns can be specified
		258	with numbered patterns, in a manner similar to the "selection" extension.
		259	The launcher can also be overridden on a per-pattern basis.
		260
		261	Example configuration:
		262
		263	URxvt.perl-ext: default,matcher
		264	URxvt.urlLauncher: sensible-browser
		265	URxvt.keysym.C-Delete: perl:matcher
		266	URxvt.matcher.button: 1
		267	URxvt.matcher.pattern.1: \\bwww\\.[\\w-]+\\.[\\w./?&@#-]*[\\w/-]
		268	URxvt.matcher.pattern.2: \\B(/\\S+?):(\\d+)(?=:|$)
		269	URxvt.matcher.launcher.2: gvim +$2 $1
		270
		271	=item xim-onthespot
		272
		273	This (experimental) perl extension implements OnTheSpot editing. It does
		274	not work perfectly, and some input methods don't seem to work well with
		275	OnTheSpot editing in general, but it seems to work at leats for SCIM and
		276	kinput2.
		277
		278	You enable it by specifying this extension and a preedit style of
		279	C<OnTheSpot>, i.e.:
		280
		281	@@RXVT_NAME@@ -pt OnTheSpot -pe xim-onthespot
		282
		283	=item kuake<hotkey>
		284
		285	A very primitive quake-console-like extension. It was inspired by a
		286	description of how the programs C<kuake> and C<yakuake> work: Whenever the
		287	user presses a global accelerator key (by default C<F10>), the terminal
		288	will show or hide itself. Another press of the accelerator key will hide
		289	or show it again.
		290
		291	Initially, the window will not be shown when using this extension.
		292
		293	This is useful if you need a single terminal thats not using any desktop
		294	space most of the time but is quickly available at the press of a key.
		295
		296	The accelerator key is grabbed regardless of any modifiers, so this
		297	extension will actually grab a physical key just for this function.
		298
		299	If you want a quake-like animation, tell your window manager to do so
		300	(fvwm can do it).
		301
		302	=item automove-background
		303
		304	This is basically a very small extension that dynamically changes the
		305	background pixmap offset to the window position, in effect creating the
		306	same effect as pseudo transparency with a custom pixmap. No scaling is
		307	supported in this mode. Example:
		308
		309	@@RXVT_NAME@@ -pixmap background.xpm -pe automove-background
		310
		311	L<http://wiki.archlinux.org/index.php/Perl_Background_Rotation/Extensions>
		312	shows how this extension can be used to implement an automatically blurred
		313	transparent background.

		320
		321	=item digital-clock
		322
		323	Displays a digital clock using the built-in overlay.
		324
		325	=item remote-clipboard
		326
		327	Somewhat of a misnomer, this extension adds two menu entries to the
		328	selection popup that allows one ti run external commands to store the
		329	selection somewhere and fetch it again.
		330
		331	We use it to implement a "distributed selection mechanism", which just
		332	means that one command uploads the file to a remote server, and another
		333	reads it.
		334
		335	The commands can be set using the C<URxvt.remote-selection.store> and
		336	C<URxvt.remote-selection.fetch> resources. The first should read the
		337	selection to store from STDIN (always in UTF-8), the second should provide
		338	the selection data on STDOUT (also in UTF-8).
		339
		340	The defaults (which are likely useless to you) use rsh and cat:
		341
		342	URxvt.remote-selection.store: rsh ruth 'cat >/tmp/distributed-selection'
		343	URxvt.remote-selection.fetch: rsh ruth 'cat /tmp/distributed-selection'
		344
		345	=item selection-pastebin
		346
		347	This is a little rarely useful extension that Uploads the selection as
		348	textfile to a remote site (or does other things). (The implementation is
		349	not currently secure for use in a multiuser environment as it writes to
		350	F</tmp> directly.).
		351
		352	It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
		353	i.e.
		354
		355	URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
		356
		357	Pressing this combination runs a command with C<%> replaced by the name of
		358	the textfile. This command can be set via a resource:
		359
		360	URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
		361
		362	And the default is likely not useful to anybody but the few people around
		363	here :)
		364
		365	The name of the textfile is the hex encoded md5 sum of the selection, so
		366	the same content should lead to the same filename.
		367
		368	After a successful upload the selection will be replaced by the text given
		369	in the C<selection-pastebin-url> resource (again, the % is the placeholder
		370	for the filename):
		371
		372	URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/%
		373
		374	I<Note to xrdb users:> xrdb uses the C preprocessor, which might interpret
		375	the double C</> characters as comment start. Use C<\057\057> instead,
		376	which works regardless of wether xrdb is used to parse the resource file
		377	or not.
