51	will enlarge the selection.	55	automatically. For this to work the extension B<must> define META
52		56	comments for its resources.
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	Don't run it in a hook, otherwise the menu will grow and grow. Instead put
113	it at the toplevel of your extension.
114
115	=item searchable-scrollback<hotkey> (enabled by default)
116
117	Adds regex search functionality to the scrollback buffer, triggered
118	by a hotkey (default: C<M-s>). While in search mode, normal terminal
119	input/output is suspended and a regex is displayed at the bottom of the
120	screen.
121
122	Inputting characters appends them to the regex and continues incremental
123	search. C<BackSpace> removes a character from the regex, C<Up> and C<Down>
124	search upwards/downwards in the scrollback buffer, C<End> jumps to the
125	bottom. C<Escape> leaves search mode and returns to the point where search
126	was started, while C<Enter> or C<Return> stay at the current position and
127	additionally stores the first match in the current line into the primary
128	selection.
129
130	=item selection-autotransform
131
132	This selection allows you to do automatic transforms on a selection
133	whenever a selection is made.
134
135	It works by specifying perl snippets (most useful is a single C<s///>
136	operator) that modify C<$_> as resources:
137
138	URxvt.selection-autotransform.0: transform
139	URxvt.selection-autotransform.1: transform
140	...
141
142	For example, the following will transform selections of the form
143	C<filename:number>, often seen in compiler messages, into C<vi +$filename
144	$word>:
145
146	URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/
147
148	And this example matches the same,but replaces it with vi-commands you can
149	paste directly into your (vi :) editor:
150
151	URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/
152
153	Of course, this can be modified to suit your needs and your editor :)
154
155	To expand the example above to typical perl error messages ("XXX at
156	FILENAME line YYY."), you need a slightly more elaborate solution:
157
158	URxvt.selection.pattern-0: ( at .*? line \\d+[,.])
159	URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/
160
161	The first line tells the selection code to treat the unchanging part of
162	every error message as a selection pattern, and the second line transforms
163	the message into vi commands to load the file.
164
165	=item mark-urls
166
167	Uses per-line display filtering (C<on_line_update>) to underline urls and
168	make them clickable. When middle-clicked, the program specified in the
169	resource C<urlLauncher> (default C<x-www-browser>) will be started with
170	the URL as first argument.
171
172	=item automove-background
173
174	This is basically a one-line extension that dynamically changes the background pixmap offset
175	to the window position, in effect creating the same effect as pseudo transparency with
176	a custom pixmap. No scaling is supported in this mode. Exmaple:
177
178	@@RXVT_NAME@@ -pixmap background.xpm -pe automove-background
179
180	=item block-graphics-to-ascii
181
182	A not very useful example of filtering all text output to the terminal,
183	by replacing all line-drawing characters (U+2500 .. U+259F) by a
184	similar-looking ascii character.
185
186	=item digital-clock
187
188	Displays a digital clock using the built-in overlay.
189
190	=item example-refresh-hooks
191
192	Displays a very simple digital clock in the upper right corner of the
193	window. Illustrates overwriting the refresh callbacks to create your own
194	overlays or changes.
195
196	=item selection-pastebin
197
198	This is a little rarely useful extension that Uploads the selection as
199	textfile to a remote site (or does other things). (The implementation is
200	not currently secure for use in a multiuser environment as it writes to
201	F</tmp> directly.).
202
203	It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
204	i.e.
205
206	URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
207
208	Pressing this combination runs a command with C<%> replaced by the name of
209	the textfile. This command can be set via a resource:
210
211	URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
212
213	And the default is likely not useful to anybody but the few people around
214	here :)
215
216	The name of the textfile is the hex encoded md5 sum of the selection, so
217	the same content should lead to the same filename.
218
219	After a successful upload the selection will be replaced by the text given
220	in the C<selection-pastebin-url> resource (again, the % is the placeholder
221	for the filename):
222
223	URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/%
