49	=item selection (enabled by default)
50
51	(More) intelligent selection. This extension tries to be more intelligent
52	when the user extends selections (double-click and further clicks). Right
53	now, it tries to select words, urls and complete shell-quoted
54	arguments, which is very convenient, too, if your F<ls> supports
55	C<--quoting-style=shell>.
56
57	A double-click usually selects the word under the cursor, further clicks
58	will enlarge the selection.
59
60	The selection works by trying to match a number of regexes and displaying
61	them in increasing order of length. You can add your own regexes by
62	specifying resources of the form:
63
64	URxvt.selection.pattern-0: perl-regex
65	URxvt.selection.pattern-1: perl-regex
66	...
67
68	The index number (0, 1...) must not have any holes, and each regex must
69	contain at least one pair of capturing parentheses, which will be used for
70	the match. For example, the following adds a regex that matches everything
71	between two vertical bars:
72
73	URxvt.selection.pattern-0: \\|([^|]+)\\|
74
75	Another example: Programs I use often output "absolute path: " at the
76	beginning of a line when they process multiple files. The following
77	pattern matches the filename (note, there is a single space at the very
78	end):
79
80	URxvt.selection.pattern-0: ^(/[^:]+):\
81
82	You can look at the source of the selection extension to see more
83	interesting uses, such as parsing a line from beginning to end.
84
85	This extension also offers following bindable keyboard commands:
86
87	=over 4
88
89	=item rot13
90
91	Rot-13 the selection when activated. Used via keyboard trigger:
92
93	URxvt.keysym.C-M-r: perl:selection:rot13
94
95	=back
96
97	=item option-popup (enabled by default)
98
99	Binds a popup menu to Ctrl-Button2 that lets you toggle (some) options at
100	runtime.
101
102	Other extensions can extend this popup menu by pushing a code reference
103	onto C<@{ $term->{option_popup_hook} }>, which gets called whenever the
104	popup is being displayed.
105
106	Its sole argument is the popup menu, which can be modified. It should
107	either return nothing or a string, the initial boolean value and a code
108	reference. The string will be used as button text and the code reference
109	will be called when the toggle changes, with the new boolean value as
110	first argument.
111
112	The following will add an entry C<myoption> that changes
113	C<$self->{myoption}>:
114
115	push @{ $self->{term}{option_popup_hook} }, sub {
116	("my option" => $myoption, sub { $self->{myoption} = $_[0] })
117	};
118
119	=item selection-popup (enabled by default)
120
121	Binds a popup menu to Ctrl-Button3 that lets you convert the selection
122	text into various other formats/action (such as uri unescaping, perl
123	evaluation, web-browser starting etc.), depending on content.
124
125	Other extensions can extend this popup menu by pushing a code reference
126	onto C<@{ $term->{selection_popup_hook} }>, which gets called whenever the
127	popup is being displayed.
128
129	Its sole argument is the popup menu, which can be modified. The selection
130	is in C<$_>, which can be used to decide whether to add something or not.
131	It should either return nothing or a string and a code reference. The
132	string will be used as button text and the code reference will be called
133	when the button gets activated and should transform C<$_>.
134
135	The following will add an entry C<a to b> that transforms all C<a>s in
136	the selection to C<b>s, but only if the selection currently contains any
137	C<a>s:
138
139	push @{ $self->{term}{selection_popup_hook} }, sub {
140	/a/ ? ("a to b" => sub { s/a/b/g }
141	: ()
142	};
143
144	=item searchable-scrollback<hotkey> (enabled by default)
145
146	Adds regex search functionality to the scrollback buffer, triggered
147	by a hotkey (default: C<M-s>). While in search mode, normal terminal
148	input/output is suspended and a regex is displayed at the bottom of the
149	screen.
150
151	Inputting characters appends them to the regex and continues incremental
152	search. C<BackSpace> removes a character from the regex, C<Up> and C<Down>
153	search upwards/downwards in the scrollback buffer, C<End> jumps to the
154	bottom. C<Escape> leaves search mode and returns to the point where search
155	was started, while C<Enter> or C<Return> stay at the current position and
156	additionally stores the first match in the current line into the primary
157	selection if the C<Shift> modifier is active.
158
159	The regex defaults to "(?i)", resulting in a case-insensitive search. To
160	get a case-sensitive search you can delete this prefix using C<BackSpace>
161	or simply use an uppercase character which removes the "(?i)" prefix.
162
163	See L<perlre> for more info about perl regular expression syntax.
164
165	=item readline (enabled by default)
166
167	A support package that tries to make editing with readline easier. At
168	the moment, it reacts to clicking shift-left mouse button by trying to
169	move the text cursor to this position. It does so by generating as many
170	cursor-left or cursor-right keypresses as required (the this only works
171	for programs that correctly support wide characters).
172
173	To avoid too many false positives, this is only done when:
174
175	=over 4
176
177	=item - the tty is in ICANON state.
178
179	=item - the text cursor is visible.
180
181	=item - the primary screen is currently being displayed.
182
183	=item - the mouse is on the same (multi-row-) line as the text cursor.
184
185	=back
186
187	The normal selection mechanism isn't disabled, so quick successive clicks
188	might interfere with selection creation in harmless ways.
189
190	=item selection-autotransform
191
192	This selection allows you to do automatic transforms on a selection
193	whenever a selection is made.
194
195	It works by specifying perl snippets (most useful is a single C<s///>
196	operator) that modify C<$_> as resources:
197
198	URxvt.selection-autotransform.0: transform
199	URxvt.selection-autotransform.1: transform
200	...
201
202	For example, the following will transform selections of the form
203	C<filename:number>, often seen in compiler messages, into C<vi +$filename
204	$word>:
205
206	URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/
207
208	And this example matches the same,but replaces it with vi-commands you can
209	paste directly into your (vi :) editor:
210
211	URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/
212
213	Of course, this can be modified to suit your needs and your editor :)
214
215	To expand the example above to typical perl error messages ("XXX at
216	FILENAME line YYY."), you need a slightly more elaborate solution:
217
218	URxvt.selection.pattern-0: ( at .*? line \\d+[,.])
219	URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/
220
221	The first line tells the selection code to treat the unchanging part of
222	every error message as a selection pattern, and the second line transforms
223	the message into vi commands to load the file.
224
225	=item tabbed
226
227	This transforms the terminal into a tabbar with additional terminals, that
228	is, it implements what is commonly referred to as "tabbed terminal". The topmost line
229	displays a "[NEW]" button, which, when clicked, will add a new tab, followed by one
230	button per tab.
231
232	Clicking a button will activate that tab. Pressing B<Shift-Left> and
233	B<Shift-Right> will switch to the tab left or right of the current one,
234	while B<Shift-Down> creates a new tab.
235
236	The tabbar itself can be configured similarly to a normal terminal, but
237	with a resource class of C<URxvt.tabbed>. In addition, it supports the
238	following four resources (shown with defaults):
239
240	URxvt.tabbed.tabbar-fg: <colour-index, default 3>
241	URxvt.tabbed.tabbar-bg: <colour-index, default 0>
242	URxvt.tabbed.tab-fg: <colour-index, default 0>
243	URxvt.tabbed.tab-bg: <colour-index, default 1>
244
245	See I<COLOR AND GRAPHICS> in the @@RXVT_NAME@@(1) manpage for valid
246	indices.
247
248	=item matcher
249
250	Uses per-line display filtering (C<on_line_update>) to underline text
251	matching a certain pattern and make it clickable. When clicked with the
252	mouse button specified in the C<matcher.button> resource (default 2, or
253	middle), the program specified in the C<matcher.launcher> resource
254	(default, the C<urlLauncher> resource, C<sensible-browser>) will be started
255	with the matched text as first argument. The default configuration is
256	suitable for matching URLs and launching a web browser, like the
257	former "mark-urls" extension.
258
259	The default pattern to match URLs can be overridden with the
260	C<matcher.pattern.0> resource, and additional patterns can be specified
261	with numbered patterns, in a manner similar to the "selection" extension.
262	The launcher can also be overridden on a per-pattern basis.
263
264	It is possible to activate the most recently seen match from the keyboard.
265	Simply bind a keysym to "perl:matcher" as seen in the example below.
266
267	Example configuration:
268
269	URxvt.perl-ext: default,matcher
270	URxvt.urlLauncher: sensible-browser
271	URxvt.keysym.C-Delete: perl:matcher
272	URxvt.matcher.button: 1
273	URxvt.matcher.pattern.1: \\bwww\\.[\\w-]+\\.[\\w./?&@#-]*[\\w/-]
274	URxvt.matcher.pattern.2: \\B(/\\S+?):(\\d+)(?=:|$)
275	URxvt.matcher.launcher.2: gvim +$2 $1
276
277	=item xim-onthespot
278
279	This (experimental) perl extension implements OnTheSpot editing. It does
280	not work perfectly, and some input methods don't seem to work well with
281	OnTheSpot editing in general, but it seems to work at least for SCIM and
282	kinput2.
283
284	You enable it by specifying this extension and a preedit style of
285	C<OnTheSpot>, i.e.:
286
287	@@RXVT_NAME@@ -pt OnTheSpot -pe xim-onthespot
288
289	=item kuake<hotkey>
290
291	A very primitive quake-console-like extension. It was inspired by a
292	description of how the programs C<kuake> and C<yakuake> work: Whenever the
293	user presses a global accelerator key (by default C<F10>), the terminal
294	will show or hide itself. Another press of the accelerator key will hide
295	or show it again.
296
297	Initially, the window will not be shown when using this extension.
298
299	This is useful if you need a single terminal that is not using any desktop
300	space most of the time but is quickly available at the press of a key.
301
302	The accelerator key is grabbed regardless of any modifiers, so this
303	extension will actually grab a physical key just for this function.
304
305	If you want a quake-like animation, tell your window manager to do so
306	(fvwm can do it).
307
308	=item automove-background
309
310	This is basically a very small extension that dynamically changes the
311	background pixmap offset to the window position, in effect creating the
312	same effect as pseudo transparency with a custom pixmap. No scaling is
313	supported in this mode. Example:
314
315	@@RXVT_NAME@@ -pixmap background.xpm -pe automove-background
316
317	L<http://wiki.archlinux.org/index.php/Perl_Background_Rotation/Extensions>
318	shows how this extension can be used to implement an automatically blurred
319	transparent background.
320
321	=item block-graphics-to-ascii
322
323	A not very useful example of filtering all text output to the terminal
324	by replacing all line-drawing characters (U+2500 .. U+259F) by a
325	similar-looking ascii character.
326
327	=item digital-clock
328
329	Displays a digital clock using the built-in overlay.
330
331	=item remote-clipboard
332
333	Somewhat of a misnomer, this extension adds two menu entries to the
334	selection popup that allows one to run external commands to store the
335	selection somewhere and fetch it again.
336
337	We use it to implement a "distributed selection mechanism", which just
338	means that one command uploads the file to a remote server, and another
339	reads it.
340
341	The commands can be set using the C<URxvt.remote-selection.store> and
342	C<URxvt.remote-selection.fetch> resources. The first should read the
343	selection to store from STDIN (always in UTF-8), the second should provide
344	the selection data on STDOUT (also in UTF-8).
345
346	The defaults (which are likely useless to you) use rsh and cat:
347
348	URxvt.remote-selection.store: rsh ruth 'cat >/tmp/distributed-selection'
349	URxvt.remote-selection.fetch: rsh ruth 'cat /tmp/distributed-selection'
350
351	=item selection-pastebin
352
353	This is a little rarely useful extension that Uploads the selection as
354	textfile to a remote site (or does other things). (The implementation is
355	not currently secure for use in a multiuser environment as it writes to
356	F</tmp> directly.).
357
358	It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
359	i.e.
360
361	URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
362
363	Pressing this combination runs a command with C<%> replaced by the name of
364	the textfile. This command can be set via a resource:
365
366	URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
367
368	And the default is likely not useful to anybody but the few people around
369	here :)
370
371	The name of the textfile is the hex encoded md5 sum of the selection, so
372	the same content should lead to the same filename.
373
374	After a successful upload the selection will be replaced by the text given
375	in the C<selection-pastebin-url> resource (again, the % is the placeholder
376	for the filename):
377
378	URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/%
379
380	I<Note to xrdb users:> xrdb uses the C preprocessor, which might interpret
381	the double C</> characters as comment start. Use C<\057\057> instead,
382	which works regardless of wether xrdb is used to parse the resource file
383	or not.
384
385	=item example-refresh-hooks
386
387	Displays a very simple digital clock in the upper right corner of the
388	window. Illustrates overwriting the refresh callbacks to create your own
389	overlays or changes.
