157get a case-sensitive search you can delete this prefix using C<BackSpace>
158or simply use an uppercase character which removes the "(?i)" prefix.
159
160See L<perlre> for more info about perl regular expression syntax.
161
162=item readline (enabled by default)
163
164A support package that tries to make editing with readline easier. At
165the moment, it reacts to clicking shift-left mouse button by trying to
166move the text cursor to this position. It does so by generating as many
167cursor-left or cursor-right keypresses as required (the this only works
168for programs that correctly support wide characters).
169
170To avoid too many false positives, this is only done when:
171
172=over 4
173
174=item - the tty is in ICANON state.
175
176=item - the text cursor is visible.
177
178=item - the primary screen is currently being displayed.
179
180=item - the mouse is on the same (multi-row-) line as the text cursor.
181
182=back
183
184The normal selection mechanism isn't disabled, so quick successive clicks
185might interfere with selection creation in harmless ways.

130 209
131=item mark-urls 210Of course, this can be modified to suit your needs and your editor :)
132 211
212To expand the example above to typical perl error messages ("XXX at
213FILENAME line YYY."), you need a slightly more elaborate solution:
214
215 URxvt.selection.pattern-0: ( at .*? line \\d+[,.])
216 URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/
217
218The first line tells the selection code to treat the unchanging part of
219every error message as a selection pattern, and the second line transforms
220the message into vi commands to load the file.
221
222=item tabbed
223
224This transforms the terminal into a tabbar with additional terminals, that
225is, it implements what is commonly referred to as "tabbed terminal". The topmost line
226displays a "[NEW]" button, which, when clicked, will add a new tab, followed by one
227button per tab.
228
229Clicking a button will activate that tab. Pressing B<Shift-Left> and
230B<Shift-Right> will switch to the tab left or right of the current one,
231while B<Shift-Down> creates a new tab.
232
233The tabbar itself can be configured similarly to a normal terminal, but
234with a resource class of C<URxvt.tabbed>. In addition, it supports the
235following four resources (shown with defaults):
236
237 URxvt.tabbed.tabbar-fg: <colour-index, default 3>
238 URxvt.tabbed.tabbar-bg: <colour-index, default 0>
239 URxvt.tabbed.tab-fg: <colour-index, default 0>
240 URxvt.tabbed.tab-bg: <colour-index, default 1>
241

243indices.

136the URL as first argument. 250middle), the program specified in the C<matcher.launcher> resource
251(default, the C<urlLauncher> resource, C<sensible-browser>) will be started
252with the matched text as first argument. The default configuration is
253suitable for matching URLs and launching a web browser, like the
254former "mark-urls" extension.
255
256The default pattern to match URLs can be overridden with the
257C<matcher.pattern.0> resource, and additional patterns can be specified
258with numbered patterns, in a manner similar to the "selection" extension.
259The launcher can also be overridden on a per-pattern basis.
260
261Example configuration:
262
263 URxvt.perl-ext: default,matcher
264 URxvt.urlLauncher: sensible-browser
265 URxvt.matcher.button: 1
266 URxvt.matcher.pattern.1: \\bwww\\.[\\w-]\\.[\\w./?&@#-]*[\\w/-]

270=item xim-onthespot
271
272This (experimental) perl extension implements OnTheSpot editing. It does
273not work perfectly, and some input methods don't seem to work well with
274OnTheSpot editing in general, but it seems to work at leats for SCIM and
275kinput2.
276
277You enable it by specifying this extension and a preedit style of
278C<OnTheSpot>, i.e.:

282=item kuake<hotkey>
283
284A very primitive quake-console-like extension. It was inspired by a
285description of how the programs C<kuake> and C<yakuake> work: Whenever the
286user presses a global accelerator key (by default C<F10>), the terminal
287will show or hide itself. Another press of the accelerator key will hide
288or show it again.
289
290Initially, the window will not be shown when using this extension.
291
292This is useful if you need a single terminal thats not using any desktop
293space most of the time but is quickly available at the press of a key.
294
295The accelerator key is grabbed regardless of any modifiers, so this
296extension will actually grab a physical key just for this function.
297
298If you want a quake-like animation, tell your window manager to do so
299(fvwm can do it).
300
301=item automove-background
302
303This is basically a very small extension that dynamically changes the
304background pixmap offset to the window position, in effect creating the
305same effect as pseudo transparency with a custom pixmap. No scaling is
306supported in this mode. Example:

319
320=item remote-clipboard
321
322Somewhat of a misnomer, this extension adds two menu entries to the
323selection popup that allows one ti run external commands to store the
324selection somewhere and fetch it again.
325
326We use it to implement a "distributed selection mechanism", which just
327means that one command uploads the file to a remote server, and another
328reads it.
329
330The commands can be set using the C<URxvt.remote-selection.store> and
331C<URxvt.remote-selection.fetch> resources. The first should read the
332selection to store from STDIN (always in UTF-8), the second should provide
333the selection data on STDOUT (also in UTF-8).
334
335The defaults (which are likely useless to you) use rsh and cat:
336
337 URxvt.remote-selection.store: rsh ruth 'cat >/tmp/distributed-selection'
338 URxvt.remote-selection.fetch: rsh ruth 'cat /tmp/distributed-selection'
339
340=item selection-pastebin
341
342This is a little rarely useful extension that Uploads the selection as
343textfile to a remote site (or does other things). (The implementation is
344not currently secure for use in a multiuser environment as it writes to
345F</tmp> directly.).
346
347It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
348i.e.
349
350 URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
351
352Pressing this combination runs a command with C<%> replaced by the name of
353the textfile. This command can be set via a resource:
354
355 URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
356
357And the default is likely not useful to anybody but the few people around
358here :)
359
360The name of the textfile is the hex encoded md5 sum of the selection, so
361the same content should lead to the same filename.
362
363After a successful upload the selection will be replaced by the text given
364in the C<selection-pastebin-url> resource (again, the % is the placeholder
365for the filename):
366
367 URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/%
368
369I<Note to xrdb users:> xrdb uses the C preprocessor, which might interpret
370the double C</> characters as comment start. Use C<\057\057> instead,
371which works regardless of wether xrdb is used to parse the resource file
372or not.
