48	(More) intelligent selection. This extension tries to be more intelligent	52	below. Similarly to builtin resources, extension resources can also be

50	now, it tries to select words, urls and complete shell-quoted	54	C<->), in which case the corresponding extension is loaded
51	arguments, which is very convenient, too, if your F<ls> supports	55	automatically. For this to work the extension B<must> define META
52	C<--quoting-style=shell>.	56	comments for its resources.
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	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 wether 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	=item readline (enabled by default)
157
158	A support package that tries to make editing with readline easier. At
159	the moment, it reacts to clicking shift-left mouse button by trying to
160	move the text cursor to this position. It does so by generating as many
161	cursor-left or cursor-right keypresses as required (the this only works
162	for programs that correctly support wide characters).
163
164	To avoid too many false positives, this is only done when:
165
166	=over 4
167
168	=item - the tty is in ICANON state.
169
170	=item - the text cursor is visible.
171
172	=item - the primary screen is currently being displayed.
173
174	=item - the mouse is on the same (multi-row-) line as the text cursor.
175
176	=back
177
178	The normal selection mechanism isn't disabled, so quick successive clicks
179	might interfere with selection creation in harmless ways.
180
181	=item selection-autotransform
182
183	This selection allows you to do automatic transforms on a selection
184	whenever a selection is made.
185
186	It works by specifying perl snippets (most useful is a single C<s///>
187	operator) that modify C<$_> as resources:
188
189	URxvt.selection-autotransform.0: transform
190	URxvt.selection-autotransform.1: transform
191	...
192
193	For example, the following will transform selections of the form
194	C<filename:number>, often seen in compiler messages, into C<vi +$filename
195	$word>:
196
197	URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/
198
199	And this example matches the same,but replaces it with vi-commands you can
200	paste directly into your (vi :) editor:
201
202	URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/
203
204	Of course, this can be modified to suit your needs and your editor :)
205
206	To expand the example above to typical perl error messages ("XXX at
207	FILENAME line YYY."), you need a slightly more elaborate solution:
208
209	URxvt.selection.pattern-0: ( at .*? line \\d+[,.])
210	URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/
211
212	The first line tells the selection code to treat the unchanging part of
213	every error message as a selection pattern, and the second line transforms
214	the message into vi commands to load the file.
215
216	=item tabbed
217
218	This transforms the terminal into a tabbar with additional terminals, that
219	is, it implements what is commonly refered to as "tabbed terminal". The topmost line
220	displays a "[NEW]" button, which, when clicked, will add a new tab, followed by one
221	button per tab.
222
223	Clicking a button will activate that tab. Pressing B<Shift-Left> and
224	B<Shift-Right> will switch to the tab left or right of the current one,
225	while B<Shift-Down> creates a new tab.
226
227	The tabbar itself can be configured similarly to a normal terminal, but
228	with a resource class of C<URxvt.tabbed>. In addition, it supports the
229	following four resources (shown with defaults):
230
231	URxvt.tabbed.tabbar-fg: <colour-index, default 3>
232	URxvt.tabbed.tabbar-bg: <colour-index, default 0>
233	URxvt.tabbed.tab-fg: <colour-index, default 0>
234	URxvt.tabbed.tab-bg: <colour-index, default 1>
235
236	See I<COLOR AND GRAPHICS> in the @@RXVT_NAME@@(1) manpage for valid
237	indices.
238
239	=item mark-urls
240
241	Uses per-line display filtering (C<on_line_update>) to underline urls and
242	make them clickable. When middle-clicked, the program specified in the
243	resource C<urlLauncher> (default C<x-www-browser>) will be started with
244	the URL as first argument.
245
246	=item xim-onthespot
247
248	This (experimental) perl extension implements OnTheSpot editing. It does
249	not work perfectly, and some input methods don't seem to work well with
250	OnTheSpot editing in general, but it seems to work at leats for SCIM and
251	kinput2.
252
253	You enable it by specifying this extension and a preedit style of
254	C<OnTheSpot>, i.e.:
255
256	@@RXVT_NAME@@ -pt OnTheSpot -pe xim-onthespot
257
258	=item automove-background
259
260	This is basically a one-line extension that dynamically changes the background pixmap offset
261	to the window position, in effect creating the same effect as pseudo transparency with
262	a custom pixmap. No scaling is supported in this mode. Exmaple:
263
264	@@RXVT_NAME@@ -pixmap background.xpm -pe automove-background
265
266	=item block-graphics-to-ascii
267
268	A not very useful example of filtering all text output to the terminal,
269	by replacing all line-drawing characters (U+2500 .. U+259F) by a
270	similar-looking ascii character.
271
272	=item digital-clock
273
274	Displays a digital clock using the built-in overlay.
275
276	=item remote-clipboard
277
278	Somewhat of a misnomer, this extension adds two menu entries to the
279	selection popup that allows one ti run external commands to store the
280	selection somewhere and fetch it again.
281
282	We use it to implement a "distributed selection mechanism", which just
283	means that one command uploads the file to a remote server, and another
284	reads it.
285
286	The commands can be set using the C<URxvt.remote-selection.store> and
287	C<URxvt.remote-selection.fetch> resources. The first should read the
288	selection to store from STDIN (always in UTF-8), the second should provide
289	the selection data on STDOUT (also in UTF-8).
290
291	The defaults (which are likely useless to you) use rsh and cat:
292
293	URxvt.remote-selection.store: rsh ruth 'cat >/tmp/distributed-selection'
294	URxvt.remote-selection.fetch: rsh ruth 'cat /tmp/distributed-selection'
295
296	=item selection-pastebin
297
298	This is a little rarely useful extension that Uploads the selection as
299	textfile to a remote site (or does other things). (The implementation is
300	not currently secure for use in a multiuser environment as it writes to
301	F</tmp> directly.).
302
303	It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
304	i.e.
305
306	URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
307
308	Pressing this combination runs a command with C<%> replaced by the name of
309	the textfile. This command can be set via a resource:
310
311	URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
312
313	And the default is likely not useful to anybody but the few people around
314	here :)
315
316	The name of the textfile is the hex encoded md5 sum of the selection, so
317	the same content should lead to the same filename.
318
319	After a successful upload the selection will be replaced by the text given
320	in the C<selection-pastebin-url> resource (again, the % is the placeholder
321	for the filename):
322
323	URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/%
324
325	=item example-refresh-hooks
326
327	Displays a very simple digital clock in the upper right corner of the
328	window. Illustrates overwriting the refresh callbacks to create your own
329	overlays or changes.
