52 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.

91=item digital-clock 109=item selection-autotransform
92 110
93Displays 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$word>:
124
125 URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/
126
127And this example matches the same,but replaces it with vi-commands you can
128paste directly into your (vi :) editor:
129
130 URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/\\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.

166
167=item selection-pastebin
168
169This is a little rarely useful extension that Uploads the selection as
170textfile to a remote site (or does other things). (The implementation is
171not currently secure for use in a multiuser environment as it writes to
172F</tmp> directly.).
173
174It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
175i.e.
176
177 URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
178
179Pressing this combination runs a command with C<%> replaced by the name of
180the textfile. This command can be set via a resource:
181
182 URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
183
184And the default is likely not useful to anybody but the few people around
185here :)
186
187The name of the textfile is the hex encoded md5 sum of the selection, so
188the same content should lead to the same filename.
189
190After a successful upload the selection will be replaced by the text given
191in the C<selection-pastebin-url> resource (again, the % is the placeholder
192for the filename):
193
194 URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/%
