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.

71This extension also offers following bindable keyboard commands:

69text into various other formats/action. 91text into various other formats/action (such as uri unescaping, perl
92evalution, web-browser starting etc.), depending on content.
70 93
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.
96
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 {

123was started, while C<Enter> or C<Return> stay at the current position and
124additionally stores the first match in the current line into the primary
125selection.
80 126
81Displays a digital clock using the built-in overlay. 127=item selection-autotransform
128
129This selection allows you to do automatic transforms on a selection
130whenever a selection is made.
131
132It works by specifying perl snippets (most useful is a single C<s///>
133operator) that modify C<$_> as resources:
134
135 URxvt.selection-autotransform.0: transform
136 URxvt.selection-autotransform.1: transform
137 ...
138
139For example, the following will transform selections of the form
140C<filename:number>, often seen in compiler messages, into C<vi +$filename
141$word>:
142
143 URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/
144
145And this example matches the same,but replaces it with vi-commands you can
146paste directly into your (vi :) editor:
147
148 URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/\\x1b:e \\Q$1\\E\\x0d:$2\\x0d/
149
150Of course, this can be modified to suit your needs and your editor :)
151
152To expand the example above to typical perl error messages ("XXX at
153FILENAME line YYY."), you need a slightly more elaborate solution:
154
155 URxvt.selection.pattern-0: ( at .*? line \\d+\\.)
156 URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)\\.$/\x1b:e \\Q$1\E\\x0d:$2\\x0d/
157
158The first line tells the selection code to treat the unchanging part of
159every error message as a selection pattern, and the second line transforms
160the message into vi commands to load the file.

185=item selection-pastebin
186
187This is a little rarely useful extension that Uploads the selection as
188textfile to a remote site (or does other things). (The implementation is
189not currently secure for use in a multiuser environment as it writes to
190F</tmp> directly.).
191
192It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
193i.e.
194
195 URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
196
197Pressing this combination runs a command with C<%> replaced by the name of
198the textfile. This command can be set via a resource:
199
200 URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
201
202And the default is likely not useful to anybody but the few people around
203here :)
204
205The name of the textfile is the hex encoded md5 sum of the selection, so
206the same content should lead to the same filename.
207
208After a successful upload the selection will be replaced by the text given
209in the C<selection-pastebin-url> resource (again, the % is the placeholder
210for the filename):
211
212 URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/%

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

365
366=item urxvt::warn $string

368Calls C<rxvt_warn> with the given string which should not include a
