		41	further clicks). Right now, it tries to select words, urls and
		42	complete shell-quoted arguments, which is very convenient, too, if
		43	your ls supports "--quoting-style=shell".
37		44
38	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	You can look at the source of the selection extension to see more
		64	interesting uses, such as parsing a line from beginning to end.
		65

		72
		73	option-popup (enabled by default)
		74	Binds a popup menu to Ctrl-Button2 that lets you toggle (some)
		75	options at runtime.
		76
		77	selection-popup (enabled by default)
		78	Binds a popup menu to Ctrl-Button3 that lets you convert the
		79	selection text into various other formats/action (such as uri
		80	unescaping, perl evaluation, web-browser starting etc.), depending
		81	on content.
		82
		83	Other extensions can extend this popup menu by pushing a code
		84	reference onto "@{ $term-"{selection_popup_hook} }>, that is called
		85	whenever the popup is displayed.
		86
		87	It's sole argument is the popup menu, which can be modified. The
		88	selection is in $_, which can be used to decide wether to add
		89	something or not. It should either return nothing or a string and a
		90	code reference. The string will be used as button text and the code
		91	reference will be called when the button gets activated and should
		92	transform $_.
		93
		94	The following will add an entry "a to b" that transforms all "a"s in
		95	the selection to "b"s, but only if the selection currently contains
		96	any "a"s:
		97
		98	push @{ $self->{term}{selection_popup_hook} }, sub {
		99	/a/ ? ("a to be" => sub { s/a/b/g }
		100	: ()
		101	};
		102
		103	searchable-scrollback<hotkey> (enabled by default)
		104	Adds regex search functionality to the scrollback buffer, triggered
		105	by a hotkey (default: "M-s"). While in search mode, normal terminal
		106	input/output is suspended and a regex is displayed at the bottom of
		107	the screen.
		108
		109	Inputting characters appends them to the regex and continues
		110	incremental search. "BackSpace" removes a character from the regex,
		111	"Up" and "Down" search upwards/downwards in the scrollback buffer,
		112	"End" jumps to the bottom. "Escape" leaves search mode and returns
		113	to the point where search was started, while "Enter" or "Return"
		114	stay at the current position and additionally stores the first match
		115	in the current line into the primary selection.
		116
		117	readline (enabled by default)
		118	A support package that tries to make editing with readline easier.
		119	At the moment, it reacts to clicking with the left mouse button by
		120	trying to move the text cursor to this position. It does so by
		121	generating as many cursor-left or cursor-right keypresses as
		122	required (the this only works for programs that correctly support
		123	wide characters).
		124
		125	To avoid too many false positives, this is only done when:
		126
		127	- the mouse is on the same (multi-row-) line as the text cursor.
		128	- the primary screen is currently being displayed.
		129	- the text cursor is visible.
		130
		131	The normal selection mechanism isn't disabled, so quick successive
		132	clicks might interfere with selection creation in harmless ways.
		133
		134	selection-autotransform
		135	This selection allows you to do automatic transforms on a selection
		136	whenever a selection is made.
		137
		138	It works by specifying perl snippets (most useful is a single "s///"
		139	operator) that modify $_ as resources:
		140
		141	URxvt.selection-autotransform.0: transform
		142	URxvt.selection-autotransform.1: transform
		143	...
		144
		145	For example, the following will transform selections of the form
		146	"filename:number", often seen in compiler messages, into "vi
		147	+$filename $word":
		148
		149	URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/
		150
		151	And this example matches the same,but replaces it with vi-commands
		152	you can paste directly into your (vi :) editor:
		153
		154	URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/
		155
		156	Of course, this can be modified to suit your needs and your editor
		157	:)
		158
		159	To expand the example above to typical perl error messages ("XXX at
		160	FILENAME line YYY."), you need a slightly more elaborate solution:
		161
		162	URxvt.selection.pattern-0: ( at .*? line \\d+[,.])
		163	URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/
		164
		165	The first line tells the selection code to treat the unchanging part
		166	of every error message as a selection pattern, and the second line
		167	transforms the message into vi commands to load the file.
		168
		169	tabbed
		170	This transforms the terminal into a tabbar with additional
		171	terminals, that is, it implements what is commonly refered to as
		172	"tabbed terminal". The topmost line displays a "[NEW]" button,
		173	which, when clicked, will add a new tab, followed by one button per
		174	tab.
		175
		176	Clicking a button will activate that tab. Pressing Shift-Left and
		177	Shift-Right will switch to the tab left or right of the current one,
		178	while Shift-Down creates a new tab.
		179
		180	mark-urls
		181	Uses per-line display filtering ("on_line_update") to underline urls
		182	and make them clickable. When middle-clicked, the program specified
		183	in the resource "urlLauncher" (default "x-www-browser") will be
		184	started with the URL as first argument.
		185
		186	automove-background
		187	This is basically a one-line extension that dynamically changes the
		188	background pixmap offset to the window position, in effect creating
		189	the same effect as pseudo transparency with a custom pixmap. No
		190	scaling is supported in this mode. Exmaple:
		191
		192	rxvt -pixmap background.xpm -pe automove-background
		193
		194	block-graphics-to-ascii
		195	A not very useful example of filtering all text output to the
		196	terminal, by replacing all line-drawing characters (U+2500 ..
		197	U+259F) by a similar-looking ascii character.

52		206
		207	selection-pastebin
		208	This is a little rarely useful extension that Uploads the selection
		209	as textfile to a remote site (or does other things). (The
		210	implementation is not currently secure for use in a multiuser
		211	environment as it writes to /tmp directly.).
		212
		213	It listens to the "selection-pastebin:remote-pastebin" keyboard
		214	command, i.e.
		215
		216	URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
		217
		218	Pressing this combination runs a command with "%" replaced by the
		219	name of the textfile. This command can be set via a resource:
		220
		221	URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
		222
		223	And the default is likely not useful to anybody but the few people
		224	around here :)
		225
		226	The name of the textfile is the hex encoded md5 sum of the
		227	selection, so the same content should lead to the same filename.
		228
		229	After a successful upload the selection will be replaced by the text
		230	given in the "selection-pastebin-url" resource (again, the % is the
		231	placeholder for the filename):
		232
		233	URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/%

64		247
		248	Argument names also often indicate the type of a parameter. Here are
		249	some hints on what they mean:
		250
		251	$text
		252	Rxvt-unicodes special way of encoding text, where one "unicode"
		253	character always represents one screen cell. See ROW_t for a
		254	discussion of this format.
		255
		256	$string
		257	A perl text string, with an emphasis on text. It can store all
		258	unicode characters and is to be distinguished with text encoded in a
		259	specific encoding (often locale-specific) and binary data.
		260
		261	$octets
		262	Either binary data or - more common - a text string encoded in a
		263	locale-specific way.
		264
		265	Extension Objects
		266	Very perl extension is a perl class. A separate perl object is created
		267	for each terminal and each extension and passed as the first parameter
		268	to hooks. So extensions can use their $self object without having to
		269	think about other extensions, with the exception of methods and members
		270	that begin with an underscore character "_": these are reserved for
		271	internal use.
		272
		273	Although it isn't a "urxvt::term" object, you can call all methods of
		274	the "urxvt::term" class on this object.
		275
		276	It has the following methods and data members:
		277
		278	$urxvt_term = $self->{term}
		279	Returns the "urxvt::term" object associated with this instance of
		280	the extension. This member must not be changed in any way.
		281
		282	$self->enable ($hook_name => $cb, [$hook_name => $cb..])
		283	Dynamically enable the given hooks (named without the "on_" prefix)
		284	for this extension, replacing any previous hook. This is useful when
		285	you want to overwrite time-critical hooks only temporarily.
		286
		287	$self->disable ($hook_name[, $hook_name..])
		288	Dynamically disable the given hooks.

		378	state information is up-to-date when this happens. For
		379	interoperability, the string should start with the extension name
		380	and a colon, to distinguish it from commands for other extensions,
		381	and this might be enforced in the future.
		382
		383	Be careful not ever to trust (in a security sense) the data you
		384	receive, as its source can not easily be controleld (e-mail content,
		385	messages from other users on the same system etc.).
		386
		387	on_add_lines $term, $string
		388	Called whenever text is about to be output, with the text as
		389	argument. You can filter/change and output the text yourself by
		390	returning a true value and calling "$term->scr_add_lines" yourself.
		391	Please note that this might be very slow, however, as your hook is
		392	called for all text being output.
		393
		394	on_tt_write $term, $octets
		395	Called whenever some data is written to the tty/pty and can be used
		396	to suppress or filter tty input.
		397
		398	on_line_update $term, $row
		399	Called whenever a line was updated or changed. Can be used to filter
		400	screen output (e.g. underline urls or other useless stuff). Only
		401	lines that are being shown will be filtered, and, due to performance
		402	reasons, not always immediately.
		403
		404	The row number is always the topmost row of the line if the line
		405	spans multiple rows.
		406
		407	Please note that, if you change the line, then the hook might get
		408	called later with the already-modified line (e.g. if unrelated parts
		409	change), so you cannot just toggle rendition bits, but only set
		410	them.

		593	Croaks (and probably outputs an error message) if the new instance
		594	couldn't be created. Returns "undef" if the new instance didn't
