139=item readline (enabled by default)
140
141A support package that tries to make editing with readline easier. At the
142moment, it reacts to clicking with the left mouse button by trying to
143move the text cursor to this position. It does so by generating as many
144cursor-left or cursor-right keypresses as required (the this only works
145for programs that correctly support wide characters).
146
147To avoid too many false positives, this is only done when:
148
149=over 4
150
151=item - the tty is in ICANON state.
152
153=item - the text cursor is visible.
154
155=item - the primary screen is currently being displayed.
156
157=item - the mouse is on the same (multi-row-) line as the text cursor.

188
189To expand the example above to typical perl error messages ("XXX at
190FILENAME line YYY."), you need a slightly more elaborate solution:
191
192 URxvt.selection.pattern-0: ( at .*? line \\d+[,.])
193 URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/
194
195The first line tells the selection code to treat the unchanging part of
196every error message as a selection pattern, and the second line transforms
197the message into vi commands to load the file.
198
199=item tabbed
200
201This transforms the terminal into a tabbar with additional terminals, that
202is, it implements what is commonly refered to as "tabbed terminal". The topmost line
203displays a "[NEW]" button, which, when clicked, will add a new tab, followed by one
204button per tab.
205
206Clicking a button will activate that tab. Pressing B<Shift-Left> and
207B<Shift-Right> will switch to the tab left or right of the current one,
208while B<Shift-Down> creates a new tab.
209
210The tabbar itself can be configured similarly to a normal terminal, but
211with a resource class of C<URxvt.tabbed>. In addition, it supports the
212following four resources (shown with defaults):
213
214 URxvt.tabbed.tabbar-fg: <colour-index, default 3>
215 URxvt.tabbed.tabbar-bg: <colour-index, default 0>
216 URxvt.tabbed.tab-fg: <colour-index, default 0>
217 URxvt.tabbed.tab-bg: <colour-index, default 1>

220indices.

231This (experimental) perl extension implements OnTheSpot editing. It does
232not work perfectly, and some input methods don't seem to work well with
233OnTheSpot editing in general, but it seems to work at leats for SCIM and
234kinput2.

258
259=item remote-clipboard
260
261Somewhat of a misnomer, this extension adds two menu entries to the
262selection popup that allows one ti run external commands to store the
263selection somewhere and fetch it again.
264
265We use it to implement a "distributed selection mechanism", which just
266means that one command uploads the file to a remote server, and another
267reads it.
268
269The commands can be set using the C<URxvt.remote-selection.store> and
270C<URxvt.remote-selection.fetch> resources. The first should read the
271selection to store from STDIN (always in UTF-8), the second should provide
272the selection data on STDOUT (also in UTF-8).
273
274The defaults (which are likely useless to you) use rsh and cat:
275
276 URxvt.remote-selection.store: rsh ruth 'cat >/tmp/distributed-selection'
277 URxvt.remote-selection.fetch: rsh ruth 'cat /tmp/distributed-selection'
278
279=item selection-pastebin
280
281This is a little rarely useful extension that Uploads the selection as
282textfile to a remote site (or does other things). (The implementation is
283not currently secure for use in a multiuser environment as it writes to
284F</tmp> directly.).
285
286It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
287i.e.
288
289 URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
290
291Pressing this combination runs a command with C<%> replaced by the name of
292the textfile. This command can be set via a resource:
293
294 URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
295
296And the default is likely not useful to anybody but the few people around
297here :)
298
299The name of the textfile is the hex encoded md5 sum of the selection, so
300the same content should lead to the same filename.
301
302After a successful upload the selection will be replaced by the text given
303in the C<selection-pastebin-url> resource (again, the % is the placeholder
304for the filename):
