98Other extensions can extend this popup menu by pushing a code reference
99onto C<@{ $term->{selection_popup_hook} }>, that is called whenever the
100popup is displayed.
101
102It's sole argument is the popup menu, which can be modified. The selection
103is in C<$_>, which can be used to decide wether to add something or not.
104It should either return nothing or a string and a code reference. The
105string will be used as button text and the code reference will be called
106when the button gets activated and should transform C<$_>.

156
157To expand the example above to typical perl error messages ("XXX at
158FILENAME line YYY."), you need a slightly more elaborate solution:
159
160 URxvt.selection.pattern-0: ( at .*? line \\d+[,.])
161 URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/
162
163The first line tells the selection code to treat the unchanging part of
164every error message as a selection pattern, and the second line transforms
165the message into vi commands to load the file.

176This is basically a one-line extension that dynamically changes the background pixmap offset

198=item selection-pastebin
199
200This is a little rarely useful extension that Uploads the selection as
201textfile to a remote site (or does other things). (The implementation is
202not currently secure for use in a multiuser environment as it writes to
203F</tmp> directly.).
204
205It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
206i.e.
207
208 URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
209
210Pressing this combination runs a command with C<%> replaced by the name of
211the textfile. This command can be set via a resource:
212
213 URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
214
215And the default is likely not useful to anybody but the few people around
216here :)
217
218The name of the textfile is the hex encoded md5 sum of the selection, so
219the same content should lead to the same filename.
220
221After a successful upload the selection will be replaced by the text given
222in the C<selection-pastebin-url> resource (again, the % is the placeholder
223for the filename):
224
225 URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/%
