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 following bindable keyboard commands:

83Upload the selection as textfile to a remote site.

87To set the command to upload the file set this resource:
88
89 URxvt.selection-pastebin-cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
90
91The % is the placeholder for the textfile. The name of the textfile is the hex encoded
92md5 sum of the selection.
93After an successful upload the selection will be replaced by the following url

61=item digital-clock 100=item option-popup (enabled by default)
62 101
63Displays a digital clock using the built-in overlay. 102Binds a popup menu to Ctrl-Button2 that lets you toggle (some) options at
103runtime.
104
105=item selection-popup (enabled by default)
106
107Binds a popup menu to Ctrl-Button3 that lets you convert the selection
108text into various other formats/action (such as uri unescaping, perl
109evalution, web-browser starting etc.), depending on content.
110
111=item searchable-scrollback<hotkey> (enabled by default)
112
113Adds regex search functionality to the scrollback buffer, triggered
114by a hotkey (default: C<M-s>). While in search mode, normal terminal
115input/output is suspended and a regex is displayed at the bottom of the
116screen.
117
118Inputting characters appends them to the regex and continues incremental
119search. C<BackSpace> removes a character from the regex, C<Up> and C<Down>
120search upwards/downwards in the scrollback buffer, C<End> jumps to the
121bottom. C<Escape> leaves search mode and returns to the point where search
122was started, while C<Enter> or C<Return> stay at the current position and
123additionally stores the first match in the current line into the primary
124selection.
125
126=item selection-autotransform
127
128This selection allows you to do automatic transforms on a selection
129whenever a selection is made.
130
131It works by specifying perl snippets (most useful is a single C<s///>
132operator) that modify C<$_> as resources:
133
134 URxvt.selection-autotransform.0: transform
135 URxvt.selection-autotransform.1: transform
136 ...
137
138For example, the following will transform selections of the form
139C<filename:number>, often seen in compiler messages, into C<vi +$filename
140$word>:
141
142 URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/
143
144And this example matches the same,but replaces it with vi-commands you can
145paste directly into your (vi :) editor:
146
147 URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/\\x1b:e \\Q$1\\E\\x0d:$2\\x0d/
148
149Of course, this can be modified to suit your needs and your editor :)
150
151To expand the example above to typical perl error messages ("XXX at
152FILENAME line YYY."), you need a slightly more elaborate solution:
153
154 URxvt.selection.pattern-0: ( at .*? line \\d+\\.)
155 URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)\\.$/\x1b:e \\Q$1\E\\x0d:$2\\x0d/
156
157The first line tells the selection code to treat the unchanging part of
158every error message as a selection pattern, and the second line transforms
159the message into vi commands to load the file.

224=head2 Extension Objects
225
226Very perl extension is a perl class. A separate perl object is created
227for each terminal and each extension and passed as the first parameter to
228hooks. So extensions can use their C<$self> object without having to think
229about other extensions, with the exception of methods and members that
230begin with an underscore character C<_>: these are reserved for internal
231use.
232
233Although it isn't a C<urxvt::term> object, you can call all methods of the
234C<urxvt::term> class on this object.
235
236It has the following methods and data members:
237
238=over 4

240=item $urxvt_term = $self->{term}

243extension. This member I<must not> be changed in any way.
244
245=item $self->enable ($hook_name => $cb, [$hook_name => $cb..])
246
247Dynamically enable the given hooks (named without the C<on_> prefix) for
248this extension, replacing any previous hook. This is useful when you want
249to overwrite time-critical hooks only temporarily.
