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:

66=item digital-clock 88=item selection-popup (enabled by default)
67 89
68Displays a digital clock using the built-in overlay. 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
94Other extensions can extend this popup menu by pushing a code reference
95onto C<@{ $term->{selection_popup_hook} }>, that is called whenever the
96popup is displayed.
97
98It's sole argument is the popup menu, which can be modified. The selection
99is in C<$_>, which can be used to decide wether to add something or not.
100It should either return nothing or a string and a code reference. The
101string will be used as button text and the code reference will be called
102when the button gets activated and should transform C<$_>.
103
104The following will add an entry C<a to b> that transforms all C<a>s in
105the selection to C<b>s, but only if the selection currently contains any
106C<a>s:
107
108 push @{ $self->{term}{selection_popup_hook} }, sub {
109 /a/ ? ("a to be" => sub { s/a/b/g }
110 : ()
111 };
112
113=item searchable-scrollback<hotkey> (enabled by default)
114
115Adds regex search functionality to the scrollback buffer, triggered
116by a hotkey (default: C<M-s>). While in search mode, normal terminal
117input/output is suspended and a regex is displayed at the bottom of the
118screen.
119
120Inputting characters appends them to the regex and continues incremental
121search. C<BackSpace> removes a character from the regex, C<Up> and C<Down>
122search upwards/downwards in the scrollback buffer, C<End> jumps to the
123bottom. C<Escape> leaves search mode and returns to the point where search
124was started, while C<Enter> or C<Return> stay at the current position and
125additionally stores the first match in the current line into the primary
126selection.
127
128=item selection-autotransform
129
130This selection allows you to do automatic transforms on a selection
131whenever a selection is made.
132
133It works by specifying perl snippets (most useful is a single C<s///>
134operator) that modify C<$_> as resources:
135
136 URxvt.selection-autotransform.0: transform
137 URxvt.selection-autotransform.1: transform
138 ...
139
140For example, the following will transform selections of the form
141C<filename:number>, often seen in compiler messages, into C<vi +$filename
142$word>:
143
144 URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/
145
146And this example matches the same,but replaces it with vi-commands you can
147paste directly into your (vi :) editor:
148
149 URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/
150
151Of course, this can be modified to suit your needs and your editor :)
152
153To expand the example above to typical perl error messages ("XXX at
154FILENAME line YYY."), you need a slightly more elaborate solution:
155
156 URxvt.selection.pattern-0: ( at .*? line \\d+[,.])
157 URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/
158
159The first line tells the selection code to treat the unchanging part of
160every error message as a selection pattern, and the second line transforms
161the message into vi commands to load the file.

166make them clickable. When middle-clicked, the program specified in the
167resource C<urlLauncher> (default C<x-www-browser>) will be started with
168the URL as first argument.
169
170=item automove-background
171
172This is basically a one-line extension that dynamically changes the background pixmap offset
173to the window position, in effect creating the same effect as pseudo transparency with
174a custom pixmap. No scaling is supported in this mode. Exmaple:

85 193
194=item selection-pastebin
195
196This is a little rarely useful extension that Uploads the selection as
197textfile to a remote site (or does other things). (The implementation is
198not currently secure for use in a multiuser environment as it writes to
199F</tmp> directly.).
200
201It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
202i.e.
203
204 URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
205
206Pressing this combination runs a command with C<%> replaced by the name of
207the textfile. This command can be set via a resource:
208
209 URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
210
211And the default is likely not useful to anybody but the few people around
212here :)
213
214The name of the textfile is the hex encoded md5 sum of the selection, so
215the same content should lead to the same filename.
216
217After a successful upload the selection will be replaced by the text given
218in the C<selection-pastebin-url> resource (again, the % is the placeholder
219for the filename):
220

263=head2 Extension Objects
264
265Very perl extension is a perl class. A separate perl object is created
266for each terminal and each extension and passed as the first parameter to
267hooks. So extensions can use their C<$self> object without having to think
268about other extensions, with the exception of methods and members that
269begin with an underscore character C<_>: these are reserved for internal
270use.
271
272Although it isn't a C<urxvt::term> object, you can call all methods of the
273C<urxvt::term> class on this object.
274
275It has the following methods and data members:

288to overwrite time-critical hooks only temporarily.

922Creates a new terminal, very similar as if you had started it with system
923C<$rxvtname, arg...>. C<$envhashref> must be a reference to a C<%ENV>-like
924hash which defines the environment of the new terminal.
925
926Croaks (and probably outputs an error message) if the new instance
927couldn't be created. Returns C<undef> if the new instance didn't
928initialise perl, and the terminal object otherwise. The C<init> and

949the user environment before exec'ing the command (e.g. C<PATH>) and should
950be preferred over explicit calls to C<exec> or C<system>.
