39		40
		41	A double-click usually selects the word under the cursor, further
		42	clicks will enlarge the selection.
		43
		44	The selection works by trying to match a number of regexes and
		45	displaying them in increasing order of length. You can add your own
		46	regexes by specifying resources of the form:
		47
		48	URxvt.selection.pattern-0: perl-regex
		49	URxvt.selection.pattern-1: perl-regex
		50	...
		51
		52	The index number (0, 1...) must not have any holes, and each regex
		53	must contain at least one pair of capturing parentheses, which will
		54	be used for the match. For example, the followign adds a regex that
		55	matches everything between two vertical bars:
		56
		57	URxvt.selection.pattern-0: \\\|([^\|]+)\\\|
		58
		59	You can look at the source of the selection extension to see more
		60	interesting uses, such as parsing a line from beginning to end.
		61

		68
		69	option-popup (enabled by default)
		70	Binds a popup menu to Ctrl-Button2 that lets you toggle (some)
		71	options at runtime.
		72
		73	selection-popup (enabled by default)
		74	Binds a popup menu to Ctrl-Button3 that lets you convert the
		75	selection text into various other formats/action (such as uri
		76	unescaping, perl evalution, web-browser starting etc.), depending on
		77	content.
		78
		79	searchable-scrollback<hotkey> (enabled by default)
		80	Adds regex search functionality to the scrollback buffer, triggered
		81	by a hotkey (default: "M-s"). While in search mode, normal terminal
		82	input/output is suspended and a regex is displayed at the bottom of
		83	the screen.
		84
		85	Inputting characters appends them to the regex and continues
		86	incremental search. "BackSpace" removes a character from the regex,
		87	"Up" and "Down" search upwards/downwards in the scrollback buffer,
		88	"End" jumps to the bottom. "Escape" leaves search mode and returns
		89	to the point where search was started, while "Enter" or "Return"
		90	stay at the current position and additionally stores the first match
		91	in the current line into the primary selection.
		92
		93	selection-autotransform
		94	This selection allows you to do automatic transforms on a selection
		95	whenever a selection is made.
		96
		97	It works by specifying perl snippets (most useful is a single "s///"
		98	operator) that modify $_ as resources:
		99
		100	URxvt.selection-autotransform.0: transform
		101	URxvt.selection-autotransform.1: transform
		102	...
		103
		104	For example, the following will transform selections of the form
		105	"filename:number", often seen in compiler messages, into "vi
		106	+$filename $word":
		107
		108	URxvt.selection-autotransform.0: s/^(\\S+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/
		109
		110	And this example matches the same,but replaces it with vi-commands
		111	you can paste directly into your (vi :) editor:
		112
		113	URxvt.selection-autotransform.0: s/^(S+):(d+):?$/\\x1b:e \\Q$1\\E\\x0d:$2\\x0d/
		114
		115	Of course, this can be modified to suit your needs and your editor
		116	:)
		117
		118	To expand the example above to typical perl error messages ("XXX at
		119	FILENAME line YYY."), you need a slightly more elaborate solution:
		120
		121	URxvt.selection.pattern-0: ( at .*? line \\d+\\.)
		122	URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)\\.$/\x1b:e \\Q$1\E\\x0d:$2\\x0d/
		123
		124	The first line tells the selection code to treat the unchanging part
		125	of every error message as a selection pattern, and the second line
		126	transforms the message into vi commands to load the file.
		127
		128	mark-urls
		129	Uses per-line display filtering ("on_line_update") to underline urls
		130	and make them clickable. When middle-clicked, the program specified
		131	in the resource "urlLauncher" (default "x-www-browser") will be
		132	started with the URL as first argument.
		133
		134	block-graphics-to-ascii
		135	A not very useful example of filtering all text output to the
		136	terminal, by replacing all line-drawing characters (U+2500 ..
		137	U+259F) by a similar-looking ascii character.

66		159
		160	Argument names also often indicate the type of a parameter. Here are
		161	some hints on what they mean:
		162
		163	$text
		164	Rxvt-unicodes special way of encoding text, where one "unicode"
		165	character always represents one screen cell. See ROW_t for a
		166	discussion of this format.
		167
		168	$string
		169	A perl text string, with an emphasis on text. It can store all
		170	unicode characters and is to be distinguished with text encoded in a
		171	specific encoding (often locale-specific) and binary data.
		172
		173	$octets
		174	Either binary data or - more common - a text string encoded in a
		175	locale-specific way.
		176
		177	Extension Objects
		178	Very perl extension is a perl class. A separate perl object is created
		179	for each terminal and each extension and passed as the first parameter
		180	to hooks. So extensions can use their $self object without having to
		181	think about other extensions, with the exception of methods and members
		182	that begin with an underscore character "_": these are reserved for
		183	internal use.
		184
		185	Although it isn't a "urxvt::term" object, you can call all methods of
		186	the "urxvt::term" class on this object.
		187
		188	It has the following methods and data members:
		189
		190	$urxvt_term = $self->{term}
		191	Returns the "urxvt::term" object associated with this instance of
		192	the extension. This member must not be changed in any way.
		193
		194	$self->enable ($hook_name => $cb, [$hook_name => $cb..])
		195	Dynamically enable the given hooks (named without the "on_" prefix)
		196	for this extension, replacing any previous hook. This is useful when
		197	you want to overwrite time-critical hooks only temporarily.
		198
		199	$self->disable ($hook_name[, $hook_name..])
		200	Dynamically disable the given hooks.

		306	Please note that, if you change the line, then the hook might get

		438	The "urxvt::anyevent" Class
		439	The sole purpose of this class is to deliver an interface to the

		443	is that you cannot use blocking APIs, but the non-blocking variant
		444	should work.
