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 following bindable keyboard commands:
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	=item remote-pastebin
82
83	Upload the selection as textfile to a remote site.
84
85	URxvt.keysym.C-M-e: perl:selection:remote-pastebin
86
87	To set the command to upload the file set this resource:
88
89	URxvt.selection-pastebin-cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
90
91	The % is the placeholder for the textfile. The name of the textfile is the hex encoded
92	md5 sum of the selection.
93	After an successful upload the selection will be replaced by the following url
94	(the % is the placeholder for the filename):
95
96	URxvt.selection-pastebin-url: http://www.ta-sa.org/files/txt/%
97
98	=back
99
100	=item option-popup (enabled by default)
101
102	Binds a popup menu to Ctrl-Button2 that lets you toggle (some) options at
103	runtime.
104
105	=item selection-popup (enabled by default)
106
107	Binds a popup menu to Ctrl-Button3 that lets you convert the selection
108	text into various other formats/action (such as uri unescaping, perl
109	evalution, web-browser starting etc.), depending on content.
110
111	=item searchable-scrollback<hotkey> (enabled by default)
112
113	Adds regex search functionality to the scrollback buffer, triggered
114	by a hotkey (default: C<M-s>). While in search mode, normal terminal
115	input/output is suspended and a regex is displayed at the bottom of the
116	screen.
117
118	Inputting characters appends them to the regex and continues incremental
119	search. C<BackSpace> removes a character from the regex, C<Up> and C<Down>
120	search upwards/downwards in the scrollback buffer, C<End> jumps to the
121	bottom. C<Escape> leaves search mode and returns to the point where search
122	was started, while C<Enter> or C<Return> stay at the current position and
123	additionally stores the first match in the current line into the primary
124	selection.
125
126	=item selection-autotransform
127
128	This selection allows you to do automatic transforms on a selection
129	whenever a selection is made.
130
131	It works by specifying perl snippets (most useful is a single C<s///>
132	operator) that modify C<$_> as resources:
133
134	URxvt.selection-autotransform.0: transform
135	URxvt.selection-autotransform.1: transform
136	...
137
138	For example, the following will transform selections of the form
139	C<filename:number>, often seen in compiler messages, into C<vi +$filename
140	$word>:
141
142	URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/
143
144	And this example matches the same,but replaces it with vi-commands you can
145	paste directly into your (vi :) editor:
146
147	URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/\\x1b:e \\Q$1\\E\\x0d:$2\\x0d/
148
149	Of course, this can be modified to suit your needs and your editor :)
150
151	To expand the example above to typical perl error messages ("XXX at
152	FILENAME line YYY."), you need a slightly more elaborate solution:
153
154	URxvt.selection.pattern-0: ( at .*? line \\d+\\.)
155	URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)\\.$/\x1b:e \\Q$1\E\\x0d:$2\\x0d/
156
157	The first line tells the selection code to treat the unchanging part of
158	every error message as a selection pattern, and the second line transforms
159	the message into vi commands to load the file.
160
161	=item mark-urls
162
163	Uses per-line display filtering (C<on_line_update>) to underline urls and
164	make them clickable. When middle-clicked, the program specified in the
165	resource C<urlLauncher> (default C<x-www-browser>) will be started with
166	the URL as first argument.
167
168	=item block-graphics-to-ascii
169
170	A not very useful example of filtering all text output to the terminal,
171	by replacing all line-drawing characters (U+2500 .. U+259F) by a
172	similar-looking ascii character.
173
174	=item digital-clock
175
176	Displays a digital clock using the built-in overlay.
177
178	=item example-refresh-hooks
179
180	Displays a very simple digital clock in the upper right corner of the
181	window. Illustrates overwriting the refresh callbacks to create your own
182	overlays or changes.
