51	arguments, which is very convenient, too, if your F<ls> supports	55	automatically. For this to work the extension B<must> define META
52	C<--quoting-style=shell>.	56	comments for its resources.
53
54	A double-click usually selects the word under the cursor, further clicks
55	will enlarge the selection.
56
57	The selection works by trying to match a number of regexes and displaying
58	them in increasing order of length. You can add your own regexes by
59	specifying resources of the form:
60
61	URxvt.selection.pattern-0: perl-regex
62	URxvt.selection.pattern-1: perl-regex
63	...
64
65	The index number (0, 1...) must not have any holes, and each regex must
66	contain at least one pair of capturing parentheses, which will be used for
67	the match. For example, the followign adds a regex that matches everything
68	between two vertical bars:
69
70	URxvt.selection.pattern-0: \\|([^|]+)\\|
71
72	You can look at the source of the selection extension to see more
73	interesting uses, such as parsing a line from beginning to end.
74
75	This extension also offers following bindable keyboard commands:
76
77	=over 4
78
79	=item rot13
80
81	Rot-13 the selection when activated. Used via keyboard trigger:
82
83	URxvt.keysym.C-M-r: perl:selection:rot13
84
85	=back
86
87	=item option-popup (enabled by default)
88
89	Binds a popup menu to Ctrl-Button2 that lets you toggle (some) options at
90	runtime.
91
92	=item selection-popup (enabled by default)
93
94	Binds a popup menu to Ctrl-Button3 that lets you convert the selection
95	text into various other formats/action (such as uri unescaping, perl
96	evalution, web-browser starting etc.), depending on content.
97
98	Other extensions can extend this popup menu by pushing a code reference
99	onto C<@{ $term->{selection_popup_hook} }>, that is called whenever the
100	popup is displayed.
101
102	It's sole argument is the popup menu, which can be modified. The selection
103	is in C<$_>, which can be used to decide wether to add something or not.
104	It should either return nothing or a string and a code reference. The
105	string will be used as button text and the code reference will be called
106	when the button gets activated and should transform C<$_>.
107
108	The following will add an entry C<a to b> that transforms all C<a>s in
109	the selection to C<b>s, but only if the selection currently contains any
110	C<a>s:
111
112	push @{ $self->{term}{selection_popup_hook} }, sub {
113	/a/ ? ("a to be" => sub { s/a/b/g }
114	: ()
115	};
116
117	=item searchable-scrollback<hotkey> (enabled by default)
118
119	Adds regex search functionality to the scrollback buffer, triggered
120	by a hotkey (default: C<M-s>). While in search mode, normal terminal
121	input/output is suspended and a regex is displayed at the bottom of the
122	screen.
123
124	Inputting characters appends them to the regex and continues incremental
125	search. C<BackSpace> removes a character from the regex, C<Up> and C<Down>
126	search upwards/downwards in the scrollback buffer, C<End> jumps to the
127	bottom. C<Escape> leaves search mode and returns to the point where search
128	was started, while C<Enter> or C<Return> stay at the current position and
129	additionally stores the first match in the current line into the primary
130	selection.
131
132	=item selection-autotransform
133
134	This selection allows you to do automatic transforms on a selection
135	whenever a selection is made.
136
137	It works by specifying perl snippets (most useful is a single C<s///>
138	operator) that modify C<$_> as resources:
139
140	URxvt.selection-autotransform.0: transform
141	URxvt.selection-autotransform.1: transform
142	...
143
144	For example, the following will transform selections of the form
145	C<filename:number>, often seen in compiler messages, into C<vi +$filename
146	$word>:
147
148	URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/
149
150	And this example matches the same,but replaces it with vi-commands you can
151	paste directly into your (vi :) editor:
152
153	URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/
154
155	Of course, this can be modified to suit your needs and your editor :)
156
157	To expand the example above to typical perl error messages ("XXX at
158	FILENAME line YYY."), you need a slightly more elaborate solution:
159
160	URxvt.selection.pattern-0: ( at .*? line \\d+[,.])
161	URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/
162
163	The first line tells the selection code to treat the unchanging part of
164	every error message as a selection pattern, and the second line transforms
165	the message into vi commands to load the file.
166
167	=item mark-urls
168
169	Uses per-line display filtering (C<on_line_update>) to underline urls and
170	make them clickable. When middle-clicked, the program specified in the
171	resource C<urlLauncher> (default C<x-www-browser>) will be started with
172	the URL as first argument.
173
174	=item automove-background
175
176	This is basically a one-line extension that dynamically changes the background pixmap offset
177	to the window position, in effect creating the same effect as pseudo transparency with
178	a custom pixmap. No scaling is supported in this mode. Exmaple:
179
180	@@RXVT_NAME@@ -pixmap background.xpm -pe automove-background
181
182	=item block-graphics-to-ascii
183
184	A not very useful example of filtering all text output to the terminal,
185	by replacing all line-drawing characters (U+2500 .. U+259F) by a
186	similar-looking ascii character.
187
188	=item digital-clock
189
190	Displays a digital clock using the built-in overlay.
191
192	=item example-refresh-hooks
193
194	Displays a very simple digital clock in the upper right corner of the
195	window. Illustrates overwriting the refresh callbacks to create your own
196	overlays or changes.
197
198	=item selection-pastebin
199
200	This is a little rarely useful extension that Uploads the selection as
201	textfile to a remote site (or does other things). (The implementation is
202	not currently secure for use in a multiuser environment as it writes to
203	F</tmp> directly.).
204
205	It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
206	i.e.
207
208	URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
209
210	Pressing this combination runs a command with C<%> replaced by the name of
211	the textfile. This command can be set via a resource:
212
213	URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
214
215	And the default is likely not useful to anybody but the few people around
216	here :)
217
218	The name of the textfile is the hex encoded md5 sum of the selection, so
219	the same content should lead to the same filename.
220
221	After a successful upload the selection will be replaced by the text given
222	in the C<selection-pastebin-url> resource (again, the % is the placeholder
223	for the filename):
224
225	URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/%
