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 followign 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:

71	=item digital-clock	105	Other extensions can extend this popup menu by pushing a code reference
		106	onto C<@{ $term->{selection_popup_hook} }>, that is called whenever the
		107	popup is displayed.
72		108
73	Displays a digital clock using the built-in overlay.	109	It's sole argument is the popup menu, which can be modified. The selection
		110	is in C<$_>, which can be used to decide wether to add something or not.
		111	It should either return nothing or a string and a code reference. The
		112	string will be used as button text and the code reference will be called
		113	when the button gets activated and should transform C<$_>.
		114
		115	The following will add an entry C<a to b> that transforms all C<a>s in
		116	the selection to C<b>s, but only if the selection currently contains any
		117	C<a>s:
		118
		119	push @{ $self->{term}{selection_popup_hook} }, sub {
		120	/a/ ? ("a to be" => sub { s/a/b/g }
		121	: ()
		122	};
		123
		124	=item searchable-scrollback<hotkey> (enabled by default)
		125
		126	Adds regex search functionality to the scrollback buffer, triggered
		127	by a hotkey (default: C<M-s>). While in search mode, normal terminal
		128	input/output is suspended and a regex is displayed at the bottom of the
		129	screen.
		130
		131	Inputting characters appends them to the regex and continues incremental
		132	search. C<BackSpace> removes a character from the regex, C<Up> and C<Down>
		133	search upwards/downwards in the scrollback buffer, C<End> jumps to the
		134	bottom. C<Escape> leaves search mode and returns to the point where search
		135	was started, while C<Enter> or C<Return> stay at the current position and
		136	additionally stores the first match in the current line into the primary
		137	selection.
		138
		139	=item readline (enabled by default)
		140
		141	A support package that tries to make editing with readline easier. At the
		142	moment, it reacts to clicking with the left mouse button by trying to
		143	move the text cursor to this position. It does so by generating as many
		144	cursor-left or cursor-right keypresses as required (the this only works
		145	for programs that correctly support wide characters).
		146
		147	To avoid too many false positives, this is only done when:
		148
		149	=over 4
		150
		151	=item - the tty is in ICANON state.
		152
		153	=item - the text cursor is visible.
		154
		155	=item - the primary screen is currently being displayed.
		156
		157	=item - the mouse is on the same (multi-row-) line as the text cursor.
		158
		159	=back
		160
		161	The normal selection mechanism isn't disabled, so quick successive clicks
		162	might interfere with selection creation in harmless ways.
		163
		164	=item selection-autotransform
		165
		166	This selection allows you to do automatic transforms on a selection
		167	whenever a selection is made.
		168
		169	It works by specifying perl snippets (most useful is a single C<s///>
		170	operator) that modify C<$_> as resources:
		171
		172	URxvt.selection-autotransform.0: transform
		173	URxvt.selection-autotransform.1: transform
		174	...
		175
		176	For example, the following will transform selections of the form
		177	C<filename:number>, often seen in compiler messages, into C<vi +$filename
		178	$word>:
		179
		180	URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/
		181
		182	And this example matches the same,but replaces it with vi-commands you can
		183	paste directly into your (vi :) editor:
		184
		185	URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/
		186
		187	Of course, this can be modified to suit your needs and your editor :)
		188
		189	To expand the example above to typical perl error messages ("XXX at
		190	FILENAME line YYY."), you need a slightly more elaborate solution:
		191
		192	URxvt.selection.pattern-0: ( at .*? line \\d+[,.])
		193	URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/
		194
		195	The first line tells the selection code to treat the unchanging part of
		196	every error message as a selection pattern, and the second line transforms
		197	the message into vi commands to load the file.
		198
		199	=item tabbed
		200
		201	This transforms the terminal into a tabbar with additional terminals, that
		202	is, it implements what is commonly refered to as "tabbed terminal". The topmost line
		203	displays a "[NEW]" button, which, when clicked, will add a new tab, followed by one
		204	button per tab.
		205
		206	Clicking a button will activate that tab. Pressing B<Shift-Left> and
		207	B<Shift-Right> will switch to the tab left or right of the current one,
		208	while B<Shift-Down> creates a new tab.
74		209
75	=item mark-urls	210	=item mark-urls
76		211
77	Uses per-line display filtering (C<on_line_update>) to underline urls.	212	Uses per-line display filtering (C<on_line_update>) to underline urls and
		213	make them clickable. When middle-clicked, the program specified in the
		214	resource C<urlLauncher> (default C<x-www-browser>) will be started with
		215	the URL as first argument.
		216
		217	=item xim-onthespot
		218
		219	This (experimental) perl extension implements OnTheSpot editing. It does
		220	not work perfectly, and some input methods don't seem to work well with
		221	OnTheSpot editing in general, but it seems to work at leats for SCIM and
		222	kinput2.
		223
		224	You enable it by specifying this extension and a preedit style of
		225	C<OnTheSpot>, i.e.:
		226
		227	@@RXVT_NAME@@ -pt OnTheSpot -pe xim-onthespot
		228
		229	=item automove-background
		230
		231	This is basically a one-line extension that dynamically changes the background pixmap offset
		232	to the window position, in effect creating the same effect as pseudo transparency with
		233	a custom pixmap. No scaling is supported in this mode. Exmaple:
		234
		235	@@RXVT_NAME@@ -pixmap background.xpm -pe automove-background

		243	=item digital-clock
		244
		245	Displays a digital clock using the built-in overlay.
		246
		247	=item remote-clipboard
		248
		249	Somewhat of a misnomer, this extension adds two menu entries to the
		250	selection popup that allows one ti run external commands to store the
		251	selection somewhere and fetch it again.
		252
		253	We use it to implement a "distributed selection mechanism", which just
		254	means that one command uploads the file to a remote server, and another
		255	reads it.
		256
		257	The commands can be set using the C<URxvt.remote-selection.store> and
		258	C<URxvt.remote-selection.fetch> resources. The first should read the
		259	selection to store from STDIN (always in UTF-8), the second should provide
		260	the selection data on STDOUT (also in UTF-8).
		261
		262	The defaults (which are likely useless to you) use rsh and cat:
		263
		264	URxvt.remote-selection.store: rsh ruth 'cat >/tmp/distributed-selection'
		265	URxvt.remote-selection.fetch: rsh ruth 'cat /tmp/distributed-selection'
		266
		267	=item selection-pastebin
		268
		269	This is a little rarely useful extension that Uploads the selection as
		270	textfile to a remote site (or does other things). (The implementation is
		271	not currently secure for use in a multiuser environment as it writes to
		272	F</tmp> directly.).
		273
		274	It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
		275	i.e.
		276
		277	URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
		278
		279	Pressing this combination runs a command with C<%> replaced by the name of
		280	the textfile. This command can be set via a resource:
		281
		282	URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
		283
		284	And the default is likely not useful to anybody but the few people around
		285	here :)
		286
		287	The name of the textfile is the hex encoded md5 sum of the selection, so
		288	the same content should lead to the same filename.
		289
		290	After a successful upload the selection will be replaced by the text given
		291	in the C<selection-pastebin-url> resource (again, the % is the placeholder
		292	for the filename):
		293
		294	URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/%

		342	=head2 Extension Objects
		343
		344	Very perl extension is a perl class. A separate perl object is created
		345	for each terminal and each extension and passed as the first parameter to
		346	hooks. So extensions can use their C<$self> object without having to think
		347	about other extensions, with the exception of methods and members that
		348	begin with an underscore character C<_>: these are reserved for internal
		349	use.
		350
		351	Although it isn't a C<urxvt::term> object, you can call all methods of the
		352	C<urxvt::term> class on this object.
