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:

83=item option-popup (enabled by default)
84
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<$_> as resources:
116
117 URxvt.selection-autotransform.0: transform
118 URxvt.selection-autotransform.1: transform
119 ...
120
121For example, the following will transform selections of the form
122C<word:number> into C<vi +$number $word>:
123
124 URxvt.selection-autotransform.0: s/^(S+):(d+):?$/vi +$2 $1\\x0d/
125
126And this example matches the same,but replaces it with vi-commands you can
127paste directory into your (vi :) editor:
128
129 URxvt.selection-autotransform.0: s/^(S+):(d+):?$/\\x1b:e $1\\x0d:$2\\x0d/
130
131=item mark-urls
132
133Uses per-line display filtering (C<on_line_update>) to underline urls and
134make them clickable. When middle-clicked, the program specified in the
135resource C<urlLauncher> (default C<x-www-browser>) will be started with
136the URL as first argument.

194=head2 Extension Objects
195
196Very perl extension is a perl class. A separate perl object is created
197for each terminal and each extension and passed as the first parameter to
198hooks. So extensions can use their C<$self> object without having to think
199about other extensions, with the exception of methods and members that
200begin with an underscore character C<_>: these are reserved for internal
201use.
202
203Although it isn't a C<urxvt::term> object, you can call all methods of the
204C<urxvt::term> class on this object.
205
206It has the following methods and data members:
207

213extension. This member I<must not> be changed in any way.

216
217Dynamically enable the given hooks (named without the C<on_> prefix) for
218this extension, replacing any previous hook. This is useful when you want
219to overwrite time-critical hooks only temporarily.
