46	now, it tries to select words, urls and complete shell-quoted
47	arguments, which is very convenient, too, if your F<ls> supports
48	C<--quoting-style=shell>.
49
50	A double-click usually selects the word under the cursor, further clicks
51	will enlarge the selection.
52
53	The selection works by trying to match a number of regexes and displaying
54	them in increasing order of length. You can add your own regexes by
55	specifying resources of the form:
56
57	URxvt.selection.pattern-0: perl-regex
58	URxvt.selection.pattern-1: perl-regex
59	...
60
61	The index number (0, 1...) must not have any holes, and each regex must
62	contain at least one pair of capturing parentheses, which will be used for
63	the match. For example, the followign adds a regex that matches everything
64	between two vertical bars:
65
66	URxvt.selection.pattern-0: \\|([^|]+)\\|
67
68	You can look at the source of the selection extension to see more
69	interesting uses, such as parsing a line from beginning to end.
70
71	This extension also offers following bindable keyboard commands:
72
73	=over 4
74
75	=item rot13
76
77	Rot-13 the selection when activated. Used via keyboard trigger:
78
79	URxvt.keysym.C-M-r: perl:selection:rot13
80
81	=back
82
83	=item option-popup (enabled by default)
84
85	Binds a popup menu to Ctrl-Button2 that lets you toggle (some) options at
86	runtime.
87
88	=item selection-popup (enabled by default)
89
90	Binds a popup menu to Ctrl-Button3 that lets you convert the selection
91	text into various other formats/action (such as uri unescaping, perl
92	evalution, web-browser starting etc.), depending on content.
93
94	Other extensions can extend this popup menu by pushing a code reference
95	onto C<@{ $term->{selection_popup_hook} }>, that is called whenever the
96	popup is displayed.
97
98	It's sole argument is the popup menu, which can be modified. The selection
99	is in C<$_>, which can be used to decide wether to add something or not.
100	It should either return nothing or a string and a code reference. The
101	string will be used as button text and the code reference will be called
102	when the button gets activated and should transform C<$_>.
103
104	The following will add an entry C<a to b> that transforms all C<a>s in
105	the selection to C<b>s, but only if the selection currently contains any
106	C<a>s:
107
108	push @{ $self->{term}{selection_popup_hook} }, sub {
109	/a/ ? ("a to be" => sub { s/a/b/g }
110	: ()
111	};
112
113	=item searchable-scrollback<hotkey> (enabled by default)
114
115	Adds regex search functionality to the scrollback buffer, triggered
116	by a hotkey (default: C<M-s>). While in search mode, normal terminal
117	input/output is suspended and a regex is displayed at the bottom of the
118	screen.
119
120	Inputting characters appends them to the regex and continues incremental
121	search. C<BackSpace> removes a character from the regex, C<Up> and C<Down>
122	search upwards/downwards in the scrollback buffer, C<End> jumps to the
123	bottom. C<Escape> leaves search mode and returns to the point where search
124	was started, while C<Enter> or C<Return> stay at the current position and
125	additionally stores the first match in the current line into the primary
126	selection.
127
128	=item selection-autotransform
129
130	This selection allows you to do automatic transforms on a selection
131	whenever a selection is made.
132
133	It works by specifying perl snippets (most useful is a single C<s///>
134	operator) that modify C<$_> as resources:
135
136	URxvt.selection-autotransform.0: transform
137	URxvt.selection-autotransform.1: transform
138	...
139
140	For example, the following will transform selections of the form
141	C<filename:number>, often seen in compiler messages, into C<vi +$filename
142	$word>:
143
144	URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/
145
146	And this example matches the same,but replaces it with vi-commands you can
147	paste directly into your (vi :) editor:
148
149	URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/
150
151	Of course, this can be modified to suit your needs and your editor :)
152
153	To expand the example above to typical perl error messages ("XXX at
154	FILENAME line YYY."), you need a slightly more elaborate solution:
155
156	URxvt.selection.pattern-0: ( at .*? line \\d+[,.])
157	URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/
158
159	The first line tells the selection code to treat the unchanging part of
160	every error message as a selection pattern, and the second line transforms
161	the message into vi commands to load the file.
162
163	=item mark-urls
164
165	Uses per-line display filtering (C<on_line_update>) to underline urls and
166	make them clickable. When middle-clicked, the program specified in the
167	resource C<urlLauncher> (default C<x-www-browser>) will be started with
168	the URL as first argument.
169
170	=item automove-background
171
172	This is basically a one-line extension that dynamically changes the background pixmap offset
173	to the window position, in effect creating the same effect as pseudo transparency with
174	a custom pixmap. No scaling is supported in this mode. Exmaple:
175
176	@@RXVT_NAME@@ -pixmap background.xpm -pe automove-background
177
178	=item block-graphics-to-ascii
179
180	A not very useful example of filtering all text output to the terminal,
181	by replacing all line-drawing characters (U+2500 .. U+259F) by a
182	similar-looking ascii character.
183
184	=item digital-clock
185
186	Displays a digital clock using the built-in overlay.
187
188	=item example-refresh-hooks
189
190	Displays a very simple digital clock in the upper right corner of the
191	window. Illustrates overwriting the refresh callbacks to create your own
192	overlays or changes.
193
194	=item selection-pastebin
195
196	This is a little rarely useful extension that Uploads the selection as
197	textfile to a remote site (or does other things). (The implementation is
198	not currently secure for use in a multiuser environment as it writes to
199	F</tmp> directly.).
200
201	It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
202	i.e.
203
204	URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
205
206	Pressing this combination runs a command with C<%> replaced by the name of
207	the textfile. This command can be set via a resource:
208
209	URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
210
211	And the default is likely not useful to anybody but the few people around
212	here :)
213
214	The name of the textfile is the hex encoded md5 sum of the selection, so
215	the same content should lead to the same filename.
216
217	After a successful upload the selection will be replaced by the text given
218	in the C<selection-pastebin-url> resource (again, the % is the placeholder
219	for the filename):
220
221	URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/%
