48C<--quoting-style=shell>.
48 49
49It also offers the following bindable event: 50A double-click usually selects the word under the cursor, further clicks
51will enlarge the selection.
52
53The selection works by trying to match a number of regexes and displaying
54them in increasing order of length. You can add your own regexes by
55specifying resources of the form:
56
57 URxvt.selection.pattern-0: perl-regex
58 URxvt.selection.pattern-1: perl-regex
59 ...
60
61The index number (0, 1...) must not have any holes, and each regex must
62contain at least one pair of capturing parentheses, which will be used for
63the match. For example, the followign adds a regex that matches everything
64between two vertical bars:
65
66 URxvt.selection.pattern-0: \\|([^|]+)\\|
67
68You can look at the source of the selection extension to see more
69interesting uses, such as parsing a line from beginning to end.
70
71This extension also offers the following bindable keyboard command:

61=item digital-clock 83=item option-popup (enabled by default)
62 84
63Displays a digital clock using the built-in overlay. 85Binds a popup menu to Ctrl-Button2 that lets you toggle (some) options at
86runtime.
87
88=item selection-popup (enabled by default)
89
90Binds a popup menu to Ctrl-Button3 that lets you convert the selection
91text into various other formats/action (such as uri unescaping, perl
92evalution, web-browser starting etc.), depending on content.
93
94=item searchable-scrollback<hotkey> (enabled by default)
95
96Adds regex search functionality to the scrollback buffer, triggered
97by a hotkey (default: C<M-s>). While in search mode, normal terminal
98input/output is suspended and a regex is displayed at the bottom of the
99screen.
100
101Inputting characters appends them to the regex and continues incremental
102search. C<BackSpace> removes a character from the regex, C<Up> and C<Down>
103search upwards/downwards in the scrollback buffer, C<End> jumps to the
104bottom. C<Escape> leaves search mode and returns to the point where search
105was started, while C<Enter> or C<Return> stay at the current position and
106additionally stores the first match in the current line into the primary
107selection.
108
109=item selection-autotransform
110
111This selection allows you to do automatic transforms on a selection
112whenever a selection is made.
113
114It works by specifying perl snippets (most useful is a single C<s///>
115operator) that modify C<$_> as resources:
116
117 URxvt.selection-autotransform.0: transform
118 URxvt.selection-autotransform.1: transform
119 ...
120
121For example, the following will transform selections of the form
122C<filename:number>, often seen in compiler messages, into C<vi +$filename
123$word>:
124
125 URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/
126
127And this example matches the same,but replaces it with vi-commands you can
128paste directly into your (vi :) editor:
129
130 URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/\\x1b:e \\Q$1\\E\\x0d:$2\\x0d/
131
132Of course, this can be modified to suit your needs and your editor :)
133
134To expand the example above to typical perl error messages ("XXX at
135FILENAME line YYY."), you need a slightly more elaborate solution:
136
137 URxvt.selection.pattern-0: ( at .*? line \\d+\\.)
138 URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)\\.$/\x1b:e \\Q$1\E\\x0d:$2\\x0d/
139
140The first line tells the selection code to treat the unchanging part of
141every error message as a selection pattern, and the second line transforms
142the message into vi commands to load the file.

207=head2 Extension Objects
208
209Very perl extension is a perl class. A separate perl object is created
210for each terminal and each extension and passed as the first parameter to
211hooks. So extensions can use their C<$self> object without having to think
212about other extensions, with the exception of methods and members that
213begin with an underscore character C<_>: these are reserved for internal
214use.
215
216Although it isn't a C<urxvt::term> object, you can call all methods of the
217C<urxvt::term> class on this object.
218
219It has the following methods and data members:
220

226extension. This member I<must not> be changed in any way.
227
228=item $self->enable ($hook_name => $cb, [$hook_name => $cb..])
229
230Dynamically enable the given hooks (named without the C<on_> prefix) for
231this extension, replacing any previous hook. This is useful when you want
232to overwrite time-critical hooks only temporarily.

234=item $self->disable ($hook_name[, $hook_name..])
