50	A double-click usually selects the word under the cursor, further clicks	54	automatically. For this to work the extension B<must> define META
51	will enlarge the selection.	55	comments for its resources.
52
53	The selection works by trying to match a number of regexes and displaying
54	them in increasing order of length. You can add your own regexes by
55	specifying resources of the form:
56
57	URxvt.selection.pattern-0: perl-regex
58	URxvt.selection.pattern-1: perl-regex
59	...
60
61	The index number (0, 1...) must not have any holes, and each regex must
62	contain at least one pair of capturing parentheses, which will be used for
63	the match. For example, the followign adds a regex that matches everything
64	between two vertical bars:
65
66	URxvt.selection.pattern-0: \\|([^|]+)\\|
67
68	You can look at the source of the selection extension to see more
69	interesting uses, such as parsing a line from beginning to end.
70
71	This extension also offers the following bindable keyboard command:
72
73	=over 4
74
75	=item rot13
76
77	Rot-13 the selection when activated. Used via keyboard trigger:
78
79	URxvt.keysym.C-M-r: perl:selection:rot13
80
81	=back
82
83	=item option-popup (enabled by default)
84
85	Binds a popup menu to Ctrl-Button2 that lets you toggle (some) options at
86	runtime.
87
88	=item selection-popup (enabled by default)
89
90	Binds a popup menu to Ctrl-Button3 that lets you convert the selection
91	text into various other formats/action (such as uri unescaping, perl
92	evalution, web-browser starting etc.), depending on content.
93
94	=item searchable-scrollback<hotkey> (enabled by default)
95
96	Adds regex search functionality to the scrollback buffer, triggered
97	by a hotkey (default: C<M-s>). While in search mode, normal terminal
98	input/output is suspended and a regex is displayed at the bottom of the
99	screen.
100
101	Inputting characters appends them to the regex and continues incremental
102	search. C<BackSpace> removes a character from the regex, C<Up> and C<Down>
103	search upwards/downwards in the scrollback buffer, C<End> jumps to the
104	bottom. C<Escape> leaves search mode and returns to the point where search
105	was started, while C<Enter> or C<Return> stay at the current position and
106	additionally stores the first match in the current line into the primary
107	selection.
108
109	=item selection-autotransform
110
111	This selection allows you to do automatic transforms on a selection
112	whenever a selection is made.
113
114	It works by specifying perl snippets (most useful is a single C<s///>
115	operator) that modify C<$_> as resources:
116
117	URxvt.selection-autotransform.0: transform
118	URxvt.selection-autotransform.1: transform
119	...
120
121	For example, the following will transform selections of the form
122	C<filename:number>, often seen in compiler messages, into C<vi +$filename
123	$word>:
124
125	URxvt.selection-autotransform.0: s/^(\\S+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/
126
127	And this example matches the same,but replaces it with vi-commands you can
128	paste directly into your (vi :) editor:
129
130	URxvt.selection-autotransform.0: s/^(S+):(d+):?$/\\x1b:e \\Q$1\\E\\x0d:$2\\x0d/
131
132	Of course, this can be modified to suit your needs and your editor :)
133
134	To expand the example above to typical perl error messages ("XXX at
135	FILENAME line YYY."), you need a slightly more elaborate solution:
136
137	URxvt.selection.pattern-0: ( at .*? line \\d+\\.)
138	URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)\\.$/\x1b:e \\Q$1\E\\x0d:$2\\x0d/
139
140	The first line tells the selection code to treat the unchanging part of
141	every error message as a selection pattern, and the second line transforms
142	the message into vi commands to load the file.
143
144	=item mark-urls
145
146	Uses per-line display filtering (C<on_line_update>) to underline urls and
147	make them clickable. When middle-clicked, the program specified in the
148	resource C<urlLauncher> (default C<x-www-browser>) will be started with
149	the URL as first argument.
150
151	=item block-graphics-to-ascii
152
153	A not very useful example of filtering all text output to the terminal,
154	by replacing all line-drawing characters (U+2500 .. U+259F) by a
155	similar-looking ascii character.
156
157	=item digital-clock
158
159	Displays a digital clock using the built-in overlay.
160
161	=item example-refresh-hooks
162
163	Displays a very simple digital clock in the upper right corner of the
164	window. Illustrates overwriting the refresh callbacks to create your own

		118
		119	Rxvt-unicode recognizes special meta comments in extensions that define
		120	different types of metadata. These comments are scanned whenever a
		121	terminal is created and are typically used to autoload extensions when
		122	their resources or command line parameters are used.
		123
		124	Currently, it recognises these comments below. Individual components are

		146
		147	#:META:RESOURCE:tr:boolean:set root pixmap as background
		148
		149	=item #:META:OSC:number:desc
		150
		151	The OSC comment specifies an OSC sequence, where C<number> is the
		152	numerical OSC code and C<desc> is a short description that is currently
		153	unused.
		154
		155	This will cause the extension to be autoloaded when the OSC sequence is
		156	used for the first time.
		157
		158	Note that autoloading carries some extra responsibilities with it:
		159	although the terminal cnanot really protect itself against malicious
		160	sources of command sequences, therefore relying on the programs running
		161	I<inside> to sanitize data that they output, it is very common for
		162	programs to emit command sequences from untrusted sources.
		163
		164	While this means that extensions should, as a defense-in-depth mechanism,
		165	always consider whether OSC sequences are safe, autoloading automatically
		166	exposes any autoloaded extension in all terminal windows, so extra care
		167	should be taken.
		168
		169	Example: the background extension registers OSC C<20> like this:
		170
		171	#:META:OSC:20:change/query background image
		172
		173	=item #:META:OSC_PERL:prefix:desc
		174
		175	The same as the OSC comment, but for the Perl OSC sequence (C<777>). The
		176	C<prefix> should be unique among extensions, of course, which is most
		177	easily arranged by using the extension name, although this is not
		178	required.
		179
		180	Example: the overlay-osc extension registers its Perl OSC like this:
