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 the following bindable keyboard command:

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.

81Displays a digital clock using the built-in overlay. 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<$_> as resources:
116
117 URxvt.selection-autotransform.0: transform
118 URxvt.selection-autotransform.1: transform
119 ...
120
121For example, the following will transform selections of the form
122C<filename:number>, often seen in compiler messages, into C<vi +$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 :)

349
350=over 4
351
352=item $term = new urxvt [arg...]
353
354Creates a new terminal, very similar as if you had started it with
355C<system $binfile, arg...>. Croaks (and probably outputs an error message)
356if the new instance couldn't be created. Returns C<undef> if the new
357instance didn't initialise perl, and the terminal object otherwise. The
358C<init> and C<start> hooks will be called during the call.
359
360=item urxvt::fatal $errormessage
361
362Fatally aborts execution with the given error message. Avoid at all
363costs! The only time this is acceptable is when the terminal process
364starts up.
365
366=item urxvt::warn $string
367
368Calls C<rxvt_warn> with the given string which should not include a
369newline. The module also overwrites the C<warn> builtin with a function
370that calls this function.
371
372Using this function has the advantage that its output ends up in the
373correct place, e.g. on stderr of the connecting urxvtc client.
374
375=item $is_safe = urxvt::safe
376
377Returns true when it is safe to do potentially unsafe things, such as
378evaluating perl code specified by the user. This is true when urxvt was
379started setuid or setgid.

856Creates a new terminal, very similar as if you had started it with system
857C<$rxvtname, arg...>. C<$envhashref> must be a reference to a C<%ENV>-like
858hash which defines the environment of the new terminal.

860Croaks (and probably outputs an error message) if the new instance
