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.

81 108
82=item digital-clock 109=item selection-autotransform
83 110
84Displays a digital clock using the built-in overlay. 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<$_> as resources:
116
117 URxvt.selection-autotransform.0: transform
118 URxvt.selection-autotransform.1: transform
119 ...
120
121For example, the following will transform selections of the form
122C<filename:number>, often seen in compiler messages, into C<vi +$filename
123$word>:
124
125 URxvt.selection-autotransform.0: s/^(\\S+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/
126
127And this example matches the same,but replaces it with vi-commands you can
128paste directly into your (vi :) editor:
129
130 URxvt.selection-autotransform.0: s/^(S+):(d+):?$/\\x1b:e \\Q$1\\E\\x0d:$2\\x0d/
131
132Of course, this can be modified to suit your needs and your editor :)
133
134To expand the example above to typical perl error messages ("XXX at
135FILENAME line YYY."), you need a slightly more elaborate solution:
136
137 URxvt.selection.pattern-0: ( at .*? line \\d+\\.)
138 URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)\\.$/\x1b:e \\Q$1\E\\x0d:$2\\x0d/
139
140The first line tells the selection code to treat the unchanging part of
141every error message as a selection pattern, and the second line transforms
142the message into vi commands to load the file.

357

359
360=item $term = new urxvt [arg...]
361
362Creates a new terminal, very similar as if you had started it with
363C<system $binfile, arg...>. Croaks (and probably outputs an error message)
364if the new instance couldn't be created. Returns C<undef> if the new
365instance didn't initialise perl, and the terminal object otherwise. The
366C<init> and C<start> hooks will be called during the call.
367
368=item urxvt::fatal $errormessage
369
370Fatally aborts execution with the given error message. Avoid at all
371costs! The only time this is acceptable is when the terminal process
372starts up.
373
374=item urxvt::warn $string
375
376Calls C<rxvt_warn> with the given string which should not include a
377newline. The module also overwrites the C<warn> builtin with a function
378that calls this function.
379
380Using this function has the advantage that its output ends up in the
381correct place, e.g. on stderr of the connecting urxvtc client.
382
383=item $is_safe = urxvt::safe

385Returns true when it is safe to do potentially unsafe things, such as
386evaluating perl code specified by the user. This is true when urxvt was
387started setuid or setgid.
