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 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 tty is in ICANON state.
145
146	=item - the text cursor is visible.
147
148	=item - the primary screen is currently being displayed.
149
150	=item - the mouse is on the same (multi-row-) line as the text cursor.
151
152	=back
153
154	The normal selection mechanism isn't disabled, so quick successive clicks
155	might interfere with selection creation in harmless ways.
156
157	=item selection-autotransform
158
159	This selection allows you to do automatic transforms on a selection
160	whenever a selection is made.
161
162	It works by specifying perl snippets (most useful is a single C<s///>
163	operator) that modify C<$_> as resources:
164
165	URxvt.selection-autotransform.0: transform
166	URxvt.selection-autotransform.1: transform
167	...
168
169	For example, the following will transform selections of the form
170	C<filename:number>, often seen in compiler messages, into C<vi +$filename
171	$word>:
172
173	URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/
174
175	And this example matches the same,but replaces it with vi-commands you can
176	paste directly into your (vi :) editor:
177
178	URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/
179
180	Of course, this can be modified to suit your needs and your editor :)
181
182	To expand the example above to typical perl error messages ("XXX at
183	FILENAME line YYY."), you need a slightly more elaborate solution:
184
185	URxvt.selection.pattern-0: ( at .*? line \\d+[,.])
186	URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/
187
188	The first line tells the selection code to treat the unchanging part of
189	every error message as a selection pattern, and the second line transforms
190	the message into vi commands to load the file.
191
192	=item tabbed
193
194	This transforms the terminal into a tabbar with additional terminals, that
195	is, it implements what is commonly refered to as "tabbed terminal". The topmost line
196	displays a "[NEW]" button, which, when clicked, will add a new tab, followed by one
197	button per tab.
198
199	Clicking a button will activate that tab. Pressing B<Shift-Left> and
200	B<Shift-Right> will switch to the tab left or right of the current one,
201	while B<Shift-Down> creates a new tab.
202
203	=item mark-urls
204
205	Uses per-line display filtering (C<on_line_update>) to underline urls and
206	make them clickable. When middle-clicked, the program specified in the
207	resource C<urlLauncher> (default C<x-www-browser>) will be started with
208	the URL as first argument.
209
210	=item automove-background
211
212	This is basically a one-line extension that dynamically changes the background pixmap offset
213	to the window position, in effect creating the same effect as pseudo transparency with
214	a custom pixmap. No scaling is supported in this mode. Exmaple:
215
216	@@RXVT_NAME@@ -pixmap background.xpm -pe automove-background
217
218	=item block-graphics-to-ascii
219
220	A not very useful example of filtering all text output to the terminal,
221	by replacing all line-drawing characters (U+2500 .. U+259F) by a
222	similar-looking ascii character.
223
224	=item digital-clock
225
226	Displays a digital clock using the built-in overlay.
227
228	=item example-refresh-hooks
229
230	Displays a very simple digital clock in the upper right corner of the
231	window. Illustrates overwriting the refresh callbacks to create your own
232	overlays or changes.
233
234	=item selection-pastebin
235
236	This is a little rarely useful extension that Uploads the selection as
237	textfile to a remote site (or does other things). (The implementation is
238	not currently secure for use in a multiuser environment as it writes to
239	F</tmp> directly.).
240
241	It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
242	i.e.
243
244	URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
245
246	Pressing this combination runs a command with C<%> replaced by the name of
247	the textfile. This command can be set via a resource:
248
249	URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
250
251	And the default is likely not useful to anybody but the few people around
252	here :)
253
254	The name of the textfile is the hex encoded md5 sum of the selection, so
255	the same content should lead to the same filename.
256
257	After a successful upload the selection will be replaced by the text given
258	in the C<selection-pastebin-url> resource (again, the % is the placeholder
259	for the filename):
260
261	URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/%
