51	arguments, which is very convenient, too, if your F<ls> supports	55	comments for its resources.
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 following adds a regex that matches everything
68	between two vertical bars:
69
70	URxvt.selection.pattern-0: \\|([^|]+)\\|
71
72	Another example: Programs I use often output "absolute path: " at the
73	beginning of a line when they process multiple files. The following
74	pattern matches the filename (note, there is a single space at the very
75	end):
76
77	URxvt.selection.pattern-0: ^(/[^:]+):\
78
79	You can look at the source of the selection extension to see more
80	interesting uses, such as parsing a line from beginning to end.
81
82	This extension also offers following bindable keyboard commands:
83
84	=over 4
85
86	=item rot13
87
88	Rot-13 the selection when activated. Used via keyboard trigger:
89
90	URxvt.keysym.C-M-r: perl:selection:rot13
91
92	=back
93
94	=item option-popup (enabled by default)
95
96	Binds a popup menu to Ctrl-Button2 that lets you toggle (some) options at
97	runtime.
98
99	Other extensions can extend this popup menu by pushing a code reference
100	onto C<@{ $term->{option_popup_hook} }>, which gets called whenever the
101	popup is being displayed.
102
103	It's sole argument is the popup menu, which can be modified. It should
104	either return nothing or a string, the initial boolean value and a code
105	reference. The string will be used as button text and the code reference
106	will be called when the toggle changes, with the new boolean value as
107	first argument.
108
109	The following will add an entry C<myoption> that changes
110	C<$self->{myoption}>:
111
112	push @{ $self->{term}{option_popup_hook} }, sub {
113	("my option" => $myoption, sub { $self->{myoption} = $_[0] })
114	};
115
116	=item selection-popup (enabled by default)
117
118	Binds a popup menu to Ctrl-Button3 that lets you convert the selection
119	text into various other formats/action (such as uri unescaping, perl
120	evaluation, web-browser starting etc.), depending on content.
121
122	Other extensions can extend this popup menu by pushing a code reference
123	onto C<@{ $term->{selection_popup_hook} }>, which gets called whenever the
124	popup is being displayed.
125
126	It's sole argument is the popup menu, which can be modified. The selection
127	is in C<$_>, which can be used to decide whether to add something or not.
128	It should either return nothing or a string and a code reference. The
129	string will be used as button text and the code reference will be called
130	when the button gets activated and should transform C<$_>.
131
132	The following will add an entry C<a to b> that transforms all C<a>s in
133	the selection to C<b>s, but only if the selection currently contains any
134	C<a>s:
135
136	push @{ $self->{term}{selection_popup_hook} }, sub {
137	/a/ ? ("a to be" => sub { s/a/b/g }
138	: ()
139	};
140
141	=item searchable-scrollback<hotkey> (enabled by default)
142
143	Adds regex search functionality to the scrollback buffer, triggered
144	by a hotkey (default: C<M-s>). While in search mode, normal terminal
145	input/output is suspended and a regex is displayed at the bottom of the
146	screen.
147
148	Inputting characters appends them to the regex and continues incremental
149	search. C<BackSpace> removes a character from the regex, C<Up> and C<Down>
150	search upwards/downwards in the scrollback buffer, C<End> jumps to the
151	bottom. C<Escape> leaves search mode and returns to the point where search
152	was started, while C<Enter> or C<Return> stay at the current position and
153	additionally stores the first match in the current line into the primary
154	selection.
155
156	The regex defaults to "(?i)", resulting in a case-insensitive search. To
157	get a case-sensitive search you can delete this prefix using C<BackSpace>
158	or simply use an uppercase character which removes the "(?i)" prefix.
159
160	See L<perlre> for more info about perl regular expression syntax.
161
162	=item readline (enabled by default)
163
164	A support package that tries to make editing with readline easier. At
165	the moment, it reacts to clicking shift-left mouse button by trying to
166	move the text cursor to this position. It does so by generating as many
167	cursor-left or cursor-right keypresses as required (the this only works
168	for programs that correctly support wide characters).
169
170	To avoid too many false positives, this is only done when:
171
172	=over 4
173
174	=item - the tty is in ICANON state.
175
176	=item - the text cursor is visible.
177
178	=item - the primary screen is currently being displayed.
179
180	=item - the mouse is on the same (multi-row-) line as the text cursor.
181
182	=back
183
184	The normal selection mechanism isn't disabled, so quick successive clicks
185	might interfere with selection creation in harmless ways.
186
187	=item selection-autotransform
188
189	This selection allows you to do automatic transforms on a selection
190	whenever a selection is made.
191
192	It works by specifying perl snippets (most useful is a single C<s///>
193	operator) that modify C<$_> as resources:
194
195	URxvt.selection-autotransform.0: transform
196	URxvt.selection-autotransform.1: transform
197	...
198
199	For example, the following will transform selections of the form
200	C<filename:number>, often seen in compiler messages, into C<vi +$filename
201	$word>:
202
203	URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/
204
205	And this example matches the same,but replaces it with vi-commands you can
206	paste directly into your (vi :) editor:
207
208	URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/
209
210	Of course, this can be modified to suit your needs and your editor :)
211
212	To expand the example above to typical perl error messages ("XXX at
213	FILENAME line YYY."), you need a slightly more elaborate solution:
214
215	URxvt.selection.pattern-0: ( at .*? line \\d+[,.])
216	URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/
217
218	The first line tells the selection code to treat the unchanging part of
219	every error message as a selection pattern, and the second line transforms
220	the message into vi commands to load the file.
221
222	=item tabbed
223
224	This transforms the terminal into a tabbar with additional terminals, that
225	is, it implements what is commonly referred to as "tabbed terminal". The topmost line
226	displays a "[NEW]" button, which, when clicked, will add a new tab, followed by one
227	button per tab.
228
229	Clicking a button will activate that tab. Pressing B<Shift-Left> and
230	B<Shift-Right> will switch to the tab left or right of the current one,
231	while B<Shift-Down> creates a new tab.
232
233	The tabbar itself can be configured similarly to a normal terminal, but
234	with a resource class of C<URxvt.tabbed>. In addition, it supports the
235	following four resources (shown with defaults):
236
237	URxvt.tabbed.tabbar-fg: <colour-index, default 3>
238	URxvt.tabbed.tabbar-bg: <colour-index, default 0>
239	URxvt.tabbed.tab-fg: <colour-index, default 0>
240	URxvt.tabbed.tab-bg: <colour-index, default 1>
241
242	See I<COLOR AND GRAPHICS> in the @@RXVT_NAME@@(1) manpage for valid
243	indices.
244
245	=item matcher
246
247	Uses per-line display filtering (C<on_line_update>) to underline text
248	matching a certain pattern and make it clickable. When clicked with the
249	mouse button specified in the C<matcher.button> resource (default 2, or
250	middle), the program specified in the C<matcher.launcher> resource
251	(default, the C<urlLauncher> resource, C<sensible-browser>) will be started
252	with the matched text as first argument. The default configuration is
253	suitable for matching URLs and launching a web browser, like the
254	former "mark-urls" extension.
255
256	The default pattern to match URLs can be overridden with the
257	C<matcher.pattern.0> resource, and additional patterns can be specified
258	with numbered patterns, in a manner similar to the "selection" extension.
259	The launcher can also be overridden on a per-pattern basis.
260
261	Example configuration:
262
263	URxvt.perl-ext: default,matcher
264	URxvt.urlLauncher: sensible-browser
265	URxvt.matcher.button: 1
266	URxvt.matcher.pattern.1: \\bwww\\.[\\w-]+\\.[\\w./?&@#-]*[\\w/-]
267	URxvt.matcher.pattern.2: \\B(/\\S+?):(\\d+)(?=:|$)
268	URxvt.matcher.launcher.2: gvim +$2 $1
269
270	=item xim-onthespot
271
272	This (experimental) perl extension implements OnTheSpot editing. It does
273	not work perfectly, and some input methods don't seem to work well with
274	OnTheSpot editing in general, but it seems to work at leats for SCIM and
275	kinput2.
276
277	You enable it by specifying this extension and a preedit style of
278	C<OnTheSpot>, i.e.:
279
280	@@RXVT_NAME@@ -pt OnTheSpot -pe xim-onthespot
281
282	=item kuake<hotkey>
283
284	A very primitive quake-console-like extension. It was inspired by a
285	description of how the programs C<kuake> and C<yakuake> work: Whenever the
286	user presses a global accelerator key (by default C<F10>), the terminal
287	will show or hide itself. Another press of the accelerator key will hide
288	or show it again.
289
290	Initially, the window will not be shown when using this extension.
291
292	This is useful if you need a single terminal thats not using any desktop
293	space most of the time but is quickly available at the press of a key.
294
295	The accelerator key is grabbed regardless of any modifiers, so this
296	extension will actually grab a physical key just for this function.
297
298	If you want a quake-like animation, tell your window manager to do so
299	(fvwm can do it).
300
301	=item automove-background
302
303	This is basically a very small extension that dynamically changes the
304	background pixmap offset to the window position, in effect creating the
305	same effect as pseudo transparency with a custom pixmap. No scaling is
306	supported in this mode. Example:
307
308	@@RXVT_NAME@@ -pixmap background.xpm -pe automove-background
309
310	=item block-graphics-to-ascii
311
312	A not very useful example of filtering all text output to the terminal
313	by replacing all line-drawing characters (U+2500 .. U+259F) by a
314	similar-looking ascii character.
315
316	=item digital-clock
317
318	Displays a digital clock using the built-in overlay.
319
320	=item remote-clipboard
321
322	Somewhat of a misnomer, this extension adds two menu entries to the
323	selection popup that allows one ti run external commands to store the
324	selection somewhere and fetch it again.
325
326	We use it to implement a "distributed selection mechanism", which just
327	means that one command uploads the file to a remote server, and another
328	reads it.
329
330	The commands can be set using the C<URxvt.remote-selection.store> and
331	C<URxvt.remote-selection.fetch> resources. The first should read the
332	selection to store from STDIN (always in UTF-8), the second should provide
333	the selection data on STDOUT (also in UTF-8).
334
335	The defaults (which are likely useless to you) use rsh and cat:
336
337	URxvt.remote-selection.store: rsh ruth 'cat >/tmp/distributed-selection'
338	URxvt.remote-selection.fetch: rsh ruth 'cat /tmp/distributed-selection'
339
340	=item selection-pastebin
341
342	This is a little rarely useful extension that Uploads the selection as
343	textfile to a remote site (or does other things). (The implementation is
344	not currently secure for use in a multiuser environment as it writes to
345	F</tmp> directly.).
346
347	It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
348	i.e.
349
350	URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
351
352	Pressing this combination runs a command with C<%> replaced by the name of
353	the textfile. This command can be set via a resource:
354
355	URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
356
357	And the default is likely not useful to anybody but the few people around
358	here :)
359
360	The name of the textfile is the hex encoded md5 sum of the selection, so
361	the same content should lead to the same filename.
362
363	After a successful upload the selection will be replaced by the text given
364	in the C<selection-pastebin-url> resource (again, the % is the placeholder
365	for the filename):
366
367	URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/%
368
369	I<Note to xrdb users:> xrdb uses the C preprocessor, which might interpret
370	the double C</> characters as comment start. Use C<\057\057> instead,
371	which works regardless of wether xrdb is used to parse the resource file
372	or not.
373
374	=item example-refresh-hooks
375
376	Displays a very simple digital clock in the upper right corner of the
377	window. Illustrates overwriting the refresh callbacks to create your own
378	overlays or changes.
