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 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.keysym.C-Delete: perl:matcher
266	URxvt.matcher.button: 1
267	URxvt.matcher.pattern.1: \\bwww\\.[\\w-]+\\.[\\w./?&@#-]*[\\w/-]
268	URxvt.matcher.pattern.2: \\B(/\\S+?):(\\d+)(?=:|$)
269	URxvt.matcher.launcher.2: gvim +$2 $1
270
271	=item xim-onthespot
272
273	This (experimental) perl extension implements OnTheSpot editing. It does
274	not work perfectly, and some input methods don't seem to work well with
275	OnTheSpot editing in general, but it seems to work at leats for SCIM and
276	kinput2.
277
278	You enable it by specifying this extension and a preedit style of
279	C<OnTheSpot>, i.e.:
280
281	@@RXVT_NAME@@ -pt OnTheSpot -pe xim-onthespot
282
283	=item kuake<hotkey>
284
285	A very primitive quake-console-like extension. It was inspired by a
286	description of how the programs C<kuake> and C<yakuake> work: Whenever the
287	user presses a global accelerator key (by default C<F10>), the terminal
288	will show or hide itself. Another press of the accelerator key will hide
289	or show it again.
290
291	Initially, the window will not be shown when using this extension.
292
293	This is useful if you need a single terminal thats not using any desktop
294	space most of the time but is quickly available at the press of a key.
295
296	The accelerator key is grabbed regardless of any modifiers, so this
297	extension will actually grab a physical key just for this function.
298
299	If you want a quake-like animation, tell your window manager to do so
300	(fvwm can do it).
301
302	=item automove-background
303
304	This is basically a very small extension that dynamically changes the
305	background pixmap offset to the window position, in effect creating the
306	same effect as pseudo transparency with a custom pixmap. No scaling is
307	supported in this mode. Example:
308
309	@@RXVT_NAME@@ -pixmap background.xpm -pe automove-background
310
311	=item block-graphics-to-ascii
312
313	A not very useful example of filtering all text output to the terminal
314	by replacing all line-drawing characters (U+2500 .. U+259F) by a
315	similar-looking ascii character.
316
317	=item digital-clock
318
319	Displays a digital clock using the built-in overlay.
320
321	=item remote-clipboard
322
323	Somewhat of a misnomer, this extension adds two menu entries to the
324	selection popup that allows one ti run external commands to store the
325	selection somewhere and fetch it again.
326
327	We use it to implement a "distributed selection mechanism", which just
328	means that one command uploads the file to a remote server, and another
329	reads it.
330
331	The commands can be set using the C<URxvt.remote-selection.store> and
332	C<URxvt.remote-selection.fetch> resources. The first should read the
333	selection to store from STDIN (always in UTF-8), the second should provide
334	the selection data on STDOUT (also in UTF-8).
335
336	The defaults (which are likely useless to you) use rsh and cat:
337
338	URxvt.remote-selection.store: rsh ruth 'cat >/tmp/distributed-selection'
339	URxvt.remote-selection.fetch: rsh ruth 'cat /tmp/distributed-selection'
340
341	=item selection-pastebin
342
343	This is a little rarely useful extension that Uploads the selection as
344	textfile to a remote site (or does other things). (The implementation is
345	not currently secure for use in a multiuser environment as it writes to
346	F</tmp> directly.).
347
348	It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
349	i.e.
350
351	URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
352
353	Pressing this combination runs a command with C<%> replaced by the name of
354	the textfile. This command can be set via a resource:
355
356	URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
357
358	And the default is likely not useful to anybody but the few people around
359	here :)
360
361	The name of the textfile is the hex encoded md5 sum of the selection, so
362	the same content should lead to the same filename.
363
364	After a successful upload the selection will be replaced by the text given
365	in the C<selection-pastebin-url> resource (again, the % is the placeholder
366	for the filename):
367
368	URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/%
369
370	I<Note to xrdb users:> xrdb uses the C preprocessor, which might interpret
371	the double C</> characters as comment start. Use C<\057\057> instead,
372	which works regardless of wether xrdb is used to parse the resource file
373	or not.
374
375	=item example-refresh-hooks
376
377	Displays a very simple digital clock in the upper right corner of the
378	window. Illustrates overwriting the refresh callbacks to create your own
379	overlays or changes.
