52C<--quoting-style=shell>.
48 53
49It also offers the following bindable event: 54A double-click usually selects the word under the cursor, further clicks
55will enlarge the selection.
56
57The selection works by trying to match a number of regexes and displaying
58them in increasing order of length. You can add your own regexes by
59specifying resources of the form:
60
61 URxvt.selection.pattern-0: perl-regex
62 URxvt.selection.pattern-1: perl-regex
63 ...
64
65The index number (0, 1...) must not have any holes, and each regex must
66contain at least one pair of capturing parentheses, which will be used for
67the match. For example, the followign adds a regex that matches everything
68between two vertical bars:
69
70 URxvt.selection.pattern-0: \\|([^|]+)\\|
71
72You can look at the source of the selection extension to see more
73interesting uses, such as parsing a line from beginning to end.
74
75This extension also offers following bindable keyboard commands:

65 91
66=item digital-clock 92=item selection-popup (enabled by default)
67 93
68Displays a digital clock using the built-in overlay. 94Binds a popup menu to Ctrl-Button3 that lets you convert the selection
95text into various other formats/action (such as uri unescaping, perl
96evalution, web-browser starting etc.), depending on content.
97
98Other extensions can extend this popup menu by pushing a code reference
99onto C<@{ $term->{selection_popup_hook} }>, that is called whenever the
100popup is displayed.
101
102It's sole argument is the popup menu, which can be modified. The selection
103is in C<$_>, which can be used to decide wether to add something or not.
104It should either return nothing or a string and a code reference. The
105string will be used as button text and the code reference will be called
106when the button gets activated and should transform C<$_>.
107
108The following will add an entry C<a to b> that transforms all C<a>s in
109the selection to C<b>s, but only if the selection currently contains any
110C<a>s:
111
112 push @{ $self->{term}{selection_popup_hook} }, sub {
113 /a/ ? ("a to be" => sub { s/a/b/g }
114 : ()
115 };
116
117=item searchable-scrollback<hotkey> (enabled by default)
118
119Adds regex search functionality to the scrollback buffer, triggered
120by a hotkey (default: C<M-s>). While in search mode, normal terminal
121input/output is suspended and a regex is displayed at the bottom of the
122screen.
123
124Inputting characters appends them to the regex and continues incremental
125search. C<BackSpace> removes a character from the regex, C<Up> and C<Down>
126search upwards/downwards in the scrollback buffer, C<End> jumps to the
127bottom. C<Escape> leaves search mode and returns to the point where search
128was started, while C<Enter> or C<Return> stay at the current position and
129additionally stores the first match in the current line into the primary
130selection.
131
132=item selection-autotransform
133
134This selection allows you to do automatic transforms on a selection
135whenever a selection is made.
136
137It works by specifying perl snippets (most useful is a single C<s///>
138operator) that modify C<$_> as resources:
139
140 URxvt.selection-autotransform.0: transform
141 URxvt.selection-autotransform.1: transform
142 ...
143
144For example, the following will transform selections of the form
145C<filename:number>, often seen in compiler messages, into C<vi +$filename
146$word>:
147
148 URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/
149
150And this example matches the same,but replaces it with vi-commands you can
151paste directly into your (vi :) editor:
152
153 URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/
154
155Of course, this can be modified to suit your needs and your editor :)
156
157To expand the example above to typical perl error messages ("XXX at
158FILENAME line YYY."), you need a slightly more elaborate solution:
159
160 URxvt.selection.pattern-0: ( at .*? line \\d+[,.])
161 URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/
162
163The first line tells the selection code to treat the unchanging part of
164every error message as a selection pattern, and the second line transforms
165the message into vi commands to load the file.

170make them clickable. When middle-clicked, the program specified in the
171resource C<urlLauncher> (default C<x-www-browser>) will be started with
172the URL as first argument.
173
174=item automove-background
175
176This is basically a one-line extension that dynamically changes the background pixmap offset
177to the window position, in effect creating the same effect as pseudo transparency with
178a custom pixmap. No scaling is supported in this mode. Exmaple:

85 197
198=item selection-pastebin
199
200This is a little rarely useful extension that Uploads the selection as
201textfile to a remote site (or does other things). (The implementation is
202not currently secure for use in a multiuser environment as it writes to
203F</tmp> directly.).
204
205It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
206i.e.
207
208 URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
209
210Pressing this combination runs a command with C<%> replaced by the name of
211the textfile. This command can be set via a resource:
212
213 URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
214
215And the default is likely not useful to anybody but the few people around
216here :)
217
218The name of the textfile is the hex encoded md5 sum of the selection, so
219the same content should lead to the same filename.
220
221After a successful upload the selection will be replaced by the text given
222in the C<selection-pastebin-url> resource (again, the % is the placeholder
223for the filename):

267=head2 Extension Objects
268
269Very perl extension is a perl class. A separate perl object is created
270for each terminal and each extension and passed as the first parameter to
271hooks. So extensions can use their C<$self> object without having to think
272about other extensions, with the exception of methods and members that
273begin with an underscore character C<_>: these are reserved for internal
274use.
275
276Although it isn't a C<urxvt::term> object, you can call all methods of the
277C<urxvt::term> class on this object.
278
279It has the following methods and data members:

292to overwrite time-critical hooks only temporarily.
