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	evaluation, 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 @{ $self->{term}{selection_popup_hook} }, sub {
113	/a/ ? ("a to be" => sub { s/a/b/g }
114	: ()
115	};
116
117	=item searchable-scrollback<hotkey> (enabled by default)
118
119	Adds regex search functionality to the scrollback buffer, triggered
120	by a hotkey (default: C<M-s>). While in search mode, normal terminal
121	input/output is suspended and a regex is displayed at the bottom of the
122	screen.
123
124	Inputting characters appends them to the regex and continues incremental
125	search. C<BackSpace> removes a character from the regex, C<Up> and C<Down>
126	search upwards/downwards in the scrollback buffer, C<End> jumps to the
127	bottom. C<Escape> leaves search mode and returns to the point where search
128	was started, while C<Enter> or C<Return> stay at the current position and
129	additionally stores the first match in the current line into the primary
130	selection.
131
132	=item readline (enabled by default)
133
134	A support package that tries to make editing with readline easier. At the
135	moment, it reacts to clicking with the left mouse button by trying to
136	move the text cursor to this position. It does so by generating as many
137	cursor-left or cursor-right keypresses as required (the this only works
138	for programs that correctly support wide characters).
139
140	To avoid too many false positives, this is only done when:
141
142	=over 4
143
144	=item - the mouse is on the same (multi-row-) line as the text cursor.
145
146	=item - the primary screen is currently being displayed.
147
148	=item - the text cursor is visible.
149
150	=back
151
152	The normal selection mechanism isn't disabled, so quick successive clicks
153	might interfere with selection creation in harmless ways.
154
155	=item selection-autotransform
156
157	This selection allows you to do automatic transforms on a selection
158	whenever a selection is made.
159
160	It works by specifying perl snippets (most useful is a single C<s///>
161	operator) that modify C<$_> as resources:
162
163	URxvt.selection-autotransform.0: transform
164	URxvt.selection-autotransform.1: transform
165	...
166
167	For example, the following will transform selections of the form
168	C<filename:number>, often seen in compiler messages, into C<vi +$filename
169	$word>:
170
171	URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/
172
173	And this example matches the same,but replaces it with vi-commands you can
174	paste directly into your (vi :) editor:
175
176	URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/
177
178	Of course, this can be modified to suit your needs and your editor :)
179
180	To expand the example above to typical perl error messages ("XXX at
181	FILENAME line YYY."), you need a slightly more elaborate solution:
182
183	URxvt.selection.pattern-0: ( at .*? line \\d+[,.])
184	URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/
185
186	The first line tells the selection code to treat the unchanging part of
187	every error message as a selection pattern, and the second line transforms
188	the message into vi commands to load the file.
189
190	=item tabbed
191
192	This transforms the terminal into a tabbar with additional terminals, that
193	is, it implements what is commonly refered to as "tabbed terminal". The topmost line
194	displays a "[NEW]" button, which, when clicked, will add a new tab, followed by one
195	button per tab.
196
197	Clicking a button will activate that tab. Pressing B<Shift-Left> and
198	B<Shift-Right> will switch to the tab left or right of the current one,
199	while B<Shift-Down> creates a new tab.
200
201	=item mark-urls
202
203	Uses per-line display filtering (C<on_line_update>) to underline urls and
204	make them clickable. When middle-clicked, the program specified in the
205	resource C<urlLauncher> (default C<x-www-browser>) will be started with
206	the URL as first argument.
207
208	=item automove-background
209
210	This is basically a one-line extension that dynamically changes the background pixmap offset
211	to the window position, in effect creating the same effect as pseudo transparency with
212	a custom pixmap. No scaling is supported in this mode. Exmaple:
213
214	@@RXVT_NAME@@ -pixmap background.xpm -pe automove-background
215
216	=item block-graphics-to-ascii
217
218	A not very useful example of filtering all text output to the terminal,
219	by replacing all line-drawing characters (U+2500 .. U+259F) by a
220	similar-looking ascii character.
221
222	=item digital-clock
223
224	Displays a digital clock using the built-in overlay.
225
226	=item example-refresh-hooks
227
228	Displays a very simple digital clock in the upper right corner of the
229	window. Illustrates overwriting the refresh callbacks to create your own
230	overlays or changes.
231
232	=item selection-pastebin
233
234	This is a little rarely useful extension that Uploads the selection as
235	textfile to a remote site (or does other things). (The implementation is
236	not currently secure for use in a multiuser environment as it writes to
237	F</tmp> directly.).
238
239	It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
240	i.e.
241
242	URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
243
244	Pressing this combination runs a command with C<%> replaced by the name of
245	the textfile. This command can be set via a resource:
246
247	URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
248
249	And the default is likely not useful to anybody but the few people around
250	here :)
251
252	The name of the textfile is the hex encoded md5 sum of the selection, so
253	the same content should lead to the same filename.
254
255	After a successful upload the selection will be replaced by the text given
256	in the C<selection-pastebin-url> resource (again, the % is the placeholder
257	for the filename):
258
259	URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/%
