46	=item selection (enabled by default)
47
48	(More) intelligent selection. This extension tries to be more intelligent
49	when the user extends selections (double-click and further clicks). Right
50	now, it tries to select words, urls and complete shell-quoted
51	arguments, which is very convenient, too, if your F<ls> supports
52	C<--quoting-style=shell>.
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 @{ $self->{term}{selection_popup_hook} }, sub {
113	/a/ ? ("a to be" => sub { s/a/b/g }
114	: ()
115	};
116
117	=item searchable-scrollback<hotkey> (enabled by default)
118
119	Adds regex search functionality to the scrollback buffer, triggered
120	by a hotkey (default: C<M-s>). While in search mode, normal terminal
121	input/output is suspended and a regex is displayed at the bottom of the
122	screen.
123
124	Inputting characters appends them to the regex and continues incremental
125	search. C<BackSpace> removes a character from the regex, C<Up> and C<Down>
126	search upwards/downwards in the scrollback buffer, C<End> jumps to the
127	bottom. C<Escape> leaves search mode and returns to the point where search
128	was started, while C<Enter> or C<Return> stay at the current position and
129	additionally stores the first match in the current line into the primary
130	selection.
131
132	=item selection-autotransform
133
134	This selection allows you to do automatic transforms on a selection
135	whenever a selection is made.
136
137	It works by specifying perl snippets (most useful is a single C<s///>
138	operator) that modify C<$_> 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 tabbed
168
169	This transforms the terminal into a tabbar with additional terminals, that
170	is, it implements what is commonly refered to as "tabbed terminal". The topmost line
171	displays a "[NEW]" button, which, when clicked, will add a new tab, followed by one
172	button per tab.
173
174	Clicking a button will activate that tab. Pressing B<Shift-Left> and
175	B<Shift-Right> will switch to the tab left or right of the current one,
176	while B<Shift-Down> creates a new tab.
177
178	=item mark-urls
179
180	Uses per-line display filtering (C<on_line_update>) to underline urls and
181	make them clickable. When middle-clicked, the program specified in the
182	resource C<urlLauncher> (default C<x-www-browser>) will be started with
183	the URL as first argument.
184
185	=item automove-background
186
187	This is basically a one-line extension that dynamically changes the background pixmap offset
188	to the window position, in effect creating the same effect as pseudo transparency with
189	a custom pixmap. No scaling is supported in this mode. Exmaple:
190
191	@@RXVT_NAME@@ -pixmap background.xpm -pe automove-background
192
193	=item block-graphics-to-ascii
194
195	A not very useful example of filtering all text output to the terminal,
196	by replacing all line-drawing characters (U+2500 .. U+259F) by a
197	similar-looking ascii character.
198
199	=item digital-clock
200
201	Displays a digital clock using the built-in overlay.
202
203	=item example-refresh-hooks
204
205	Displays a very simple digital clock in the upper right corner of the
206	window. Illustrates overwriting the refresh callbacks to create your own
207	overlays or changes.
208
209	=item selection-pastebin
210
211	This is a little rarely useful extension that Uploads the selection as
212	textfile to a remote site (or does other things). (The implementation is
213	not currently secure for use in a multiuser environment as it writes to
214	F</tmp> directly.).
215
216	It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
217	i.e.
218
219	URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
220
221	Pressing this combination runs a command with C<%> replaced by the name of
222	the textfile. This command can be set via a resource:
223
224	URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
225
226	And the default is likely not useful to anybody but the few people around
227	here :)
228
229	The name of the textfile is the hex encoded md5 sum of the selection, so
230	the same content should lead to the same filename.
231
232	After a successful upload the selection will be replaced by the text given
233	in the C<selection-pastebin-url> resource (again, the % is the placeholder
234	for the filename):
235
236	URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/%
