45	when the user extends selections (double-click and further clicks). Right	49	loaded automatically when used.
46	now, it tries to select words, urls and complete shell-quoted
47	arguments, which is very convenient, too, if your F<ls> supports
48	C<--quoting-style=shell>.
49
50	A double-click usually selects the word under the cursor, further clicks
51	will enlarge the selection.
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	=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	Other extensions can extend this popup menu by pushing a code reference onto
95	C<@urxvt::ext::selection_popup::hook>, that is called whenever the popup is displayed.
96
97	It's sole argument is the popup menu, which can be modified. The selection
98	is in C<$_>, which can be used to decide wether to add something or not.
99	It should either return nothing or a string and a code reference. The
100	string will be used as button text and the code reference will be called
101	when the button gets activated and should transform C<$_>.
102
103	The following will add an entry C<a to b> that transforms all C<a>s in
104	the selection to C<b>s, but only if the selection currently contains any
105	C<a>s:
106
107	push urxvt::ext::selection_popup::hook, sub {
108	/a/ ? ("a to be" => sub { s/a/b/g }
109	: ()
110	};
111
112	=item searchable-scrollback<hotkey> (enabled by default)
113
114	Adds regex search functionality to the scrollback buffer, triggered
115	by a hotkey (default: C<M-s>). While in search mode, normal terminal
116	input/output is suspended and a regex is displayed at the bottom of the
117	screen.
118
119	Inputting characters appends them to the regex and continues incremental
120	search. C<BackSpace> removes a character from the regex, C<Up> and C<Down>
121	search upwards/downwards in the scrollback buffer, C<End> jumps to the
122	bottom. C<Escape> leaves search mode and returns to the point where search
123	was started, while C<Enter> or C<Return> stay at the current position and
124	additionally stores the first match in the current line into the primary
125	selection.
126
127	=item selection-autotransform
128
129	This selection allows you to do automatic transforms on a selection
130	whenever a selection is made.
131
132	It works by specifying perl snippets (most useful is a single C<s///>
133	operator) that modify C<$_> as resources:
134
135	URxvt.selection-autotransform.0: transform
136	URxvt.selection-autotransform.1: transform
137	...
138
139	For example, the following will transform selections of the form
140	C<filename:number>, often seen in compiler messages, into C<vi +$filename
141	$word>:
142
143	URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/
144
145	And this example matches the same,but replaces it with vi-commands you can
146	paste directly into your (vi :) editor:
147
148	URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/\\x1b:e \\Q$1\\E\\x0d:$2\\x0d/
149
150	Of course, this can be modified to suit your needs and your editor :)
151
152	To expand the example above to typical perl error messages ("XXX at
153	FILENAME line YYY."), you need a slightly more elaborate solution:
154
155	URxvt.selection.pattern-0: ( at .*? line \\d+\\.)
156	URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)\\.$/\x1b:e \\Q$1\E\\x0d:$2\\x0d/
157
158	The first line tells the selection code to treat the unchanging part of
159	every error message as a selection pattern, and the second line transforms
160	the message into vi commands to load the file.
161
162	=item mark-urls
163
164	Uses per-line display filtering (C<on_line_update>) to underline urls and
165	make them clickable. When middle-clicked, the program specified in the
166	resource C<urlLauncher> (default C<x-www-browser>) will be started with
167	the URL as first argument.
168
169	=item block-graphics-to-ascii
170
171	A not very useful example of filtering all text output to the terminal,
172	by replacing all line-drawing characters (U+2500 .. U+259F) by a
173	similar-looking ascii character.
174
175	=item digital-clock
176
177	Displays a digital clock using the built-in overlay.
178
179	=item example-refresh-hooks
180
181	Displays a very simple digital clock in the upper right corner of the
182	window. Illustrates overwriting the refresh callbacks to create your own
183	overlays or changes.
184
185	=item selection-pastebin
186
187	This is a little rarely useful extension that Uploads the selection as
188	textfile to a remote site (or does other things). (The implementation is
189	not currently secure for use in a multiuser environment as it writes to
190	F</tmp> directly.).
191
192	It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
193	i.e.
194
195	URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
196
197	Pressing this combination runs a command with C<%> replaced by the name of
198	the textfile. This command can be set via a resource:
199
200	URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
201
202	And the default is likely not useful to anybody but the few people around
203	here :)
204
205	The name of the textfile is the hex encoded md5 sum of the selection, so
206	the same content should lead to the same filename.
207
208	After a successful upload the selection will be replaced by the text given
209	in the C<selection-pastebin-url> resource (again, the % is the placeholder
210	for the filename):
211
212	URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/%
