41 45
42=item selection (enabled by default) 46 URxvt.perl-ext-common: default,selection-autotransform
43 47
44(More) intelligent selection. This extension tries to be more intelligent 48Extensions that add command line parameters or resources on their own are
45when the user extends selections (double-click and further clicks). Right 49loaded automatically when used.
46now, it tries to select words, urls and complete shell-quoted
47arguments, which is very convenient, too, if your F<ls> supports
48C<--quoting-style=shell>.
49
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:
72
73=over 4
74
75=item rot13
76
77Rot-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
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.
137
138=item block-graphics-to-ascii
139
140A not very useful example of filtering all text output to the terminal,
141by replacing all line-drawing characters (U+2500 .. U+259F) by a
142similar-looking ascii character.
143
144=item digital-clock
145
146Displays a digital clock using the built-in overlay.
147
148=item example-refresh-hooks
149
150Displays a very simple digital clock in the upper right corner of the
151window. Illustrates overwriting the refresh callbacks to create your own
152overlays or changes.

783=head2 The C<urxvt::term::extension> class
784
785Each extension attached to a terminal object is represented by
786a C<urxvt::term::extension> object.
787
788You can use these objects, which are passed to all callbacks to store any
789state related to the terminal and extension instance.
790
791The methods (And data members) documented below can be called on extension
792objects, in addition to call methods documented for the <urxvt::term>
793class.

836
837Dynamically enable the given hooks (named without the C<on_> prefix) for
838this extension, replacing any hook previously installed via C<enable> in
839this extension.
840
841This is useful when you want to overwrite time-critical hooks only
842temporarily.
843
844To install additional callbacks for the same hook, you can use the C<on>
845method of the C<urxvt::term> class.

885Similar to the C<enable> enable, but installs additional callbacks for
886the given hook(s) (that is, it doesn't replace existing callbacks), and
887returns a guard object. When the guard object is destroyed the callbacks
