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:

70 93
71=item digital-clock 94Other extensions can extend this popup menu by pushing a code reference onto
95C<@urxvt::ext::selection_popup::hook>, that is called whenever the popup is displayed.
72 96
73Displays a digital clock using the built-in overlay. 97It's sole argument is the popup menu, which can be modified. The selection
98is in C<$_>, which can be used to decide wether to add something or not.
99It should either return nothing or a string and a code reference. The
100string will be used as button text and the code reference will be called
101when the button gets activated and should transform C<$_>.
102
103The following will add an entry C<a to b> that transforms all C<a>s in
104the selection to C<b>s, but only if the selection currently contains any
105C<a>s:
106
107 push urxvt::ext::selection_popup::hook, sub {
108 /a/ ? ("a to be" => sub { s/a/b/g }
109 : ()
110 };
111
112Don't run it in a hook, otherwise the menu will grow and grow. Instead put
113it at the toplevel of your extension.
114
115=item searchable-scrollback<hotkey> (enabled by default)
116
117Adds regex search functionality to the scrollback buffer, triggered
118by a hotkey (default: C<M-s>). While in search mode, normal terminal
119input/output is suspended and a regex is displayed at the bottom of the
120screen.
121
122Inputting characters appends them to the regex and continues incremental
123search. C<BackSpace> removes a character from the regex, C<Up> and C<Down>
124search upwards/downwards in the scrollback buffer, C<End> jumps to the
125bottom. C<Escape> leaves search mode and returns to the point where search
126was started, while C<Enter> or C<Return> stay at the current position and
127additionally stores the first match in the current line into the primary
128selection.
129
130=item selection-autotransform
131
132This selection allows you to do automatic transforms on a selection
133whenever a selection is made.
134
135It works by specifying perl snippets (most useful is a single C<s///>
136operator) that modify C<$_> as resources:
137
138 URxvt.selection-autotransform.0: transform
139 URxvt.selection-autotransform.1: transform
140 ...
141
142For example, the following will transform selections of the form
143C<filename:number>, often seen in compiler messages, into C<vi +$filename
144$word>:
145
146 URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/
147
148And this example matches the same,but replaces it with vi-commands you can
149paste directly into your (vi :) editor:
150
151 URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/
152
153Of course, this can be modified to suit your needs and your editor :)
154
155To expand the example above to typical perl error messages ("XXX at
156FILENAME line YYY."), you need a slightly more elaborate solution:
157
158 URxvt.selection.pattern-0: ( at .*? line \\d+[,.])
159 URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/
160
161The first line tells the selection code to treat the unchanging part of
162every error message as a selection pattern, and the second line transforms
163the message into vi commands to load the file.

168make them clickable. When middle-clicked, the program specified in the
169resource C<urlLauncher> (default C<x-www-browser>) will be started with
170the URL as first argument.
171
172=item automove-background
173
174This is basically a one-line extension that dynamically changes the background pixmap offset
175to the window position, in effect creating the same effect as pseudo transparency with
176a custom pixmap. No scaling is supported in this mode. Exmaple:

196=item selection-pastebin
197
198This is a little rarely useful extension that Uploads the selection as
199textfile to a remote site (or does other things). (The implementation is
200not currently secure for use in a multiuser environment as it writes to
201F</tmp> directly.).
202
203It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
204i.e.
205
206 URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
207
208Pressing this combination runs a command with C<%> replaced by the name of
209the textfile. This command can be set via a resource:
210
211 URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
212
213And the default is likely not useful to anybody but the few people around
214here :)
215
216The name of the textfile is the hex encoded md5 sum of the selection, so
217the same content should lead to the same filename.
218
219After a successful upload the selection will be replaced by the text given
220in the C<selection-pastebin-url> resource (again, the % is the placeholder
221for the filename):
222

265=head2 Extension Objects
266
267Very perl extension is a perl class. A separate perl object is created
268for each terminal and each extension and passed as the first parameter to
269hooks. So extensions can use their C<$self> object without having to think
270about other extensions, with the exception of methods and members that
271begin with an underscore character C<_>: these are reserved for internal
272use.
273
274Although it isn't a C<urxvt::term> object, you can call all methods of the
275C<urxvt::term> class on this object.

277It has the following methods and data members:

951the user environment before exec'ing the command (e.g. C<PATH>) and should
