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.

180=item - the mouse is on the same (multi-row-) line as the text cursor.

161=item mark-urls 222=item tabbed
162 223
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>

243indices.

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.

271=item xim-onthespot
272
273This (experimental) perl extension implements OnTheSpot editing. It does
274not work perfectly, and some input methods don't seem to work well with
275OnTheSpot editing in general, but it seems to work at leats for SCIM and
276kinput2.
277
278You enable it by specifying this extension and a preedit style of
279C<OnTheSpot>, i.e.:

282
283=item kuake<hotkey>
284
285A very primitive quake-console-like extension. It was inspired by a
286description of how the programs C<kuake> and C<yakuake> work: Whenever the
287user presses a global accelerator key (by default C<F10>), the terminal
288will show or hide itself. Another press of the accelerator key will hide
289or show it again.
290
291Initially, the window will not be shown when using this extension.
292
293This is useful if you need a single terminal thats not using any desktop
294space most of the time but is quickly available at the press of a key.
295
296The accelerator key is grabbed regardless of any modifiers, so this
297extension will actually grab a physical key just for this function.
298
299If you want a quake-like animation, tell your window manager to do so
300(fvwm can do it).
301
302=item automove-background
303
304This is basically a very small extension that dynamically changes the
305background pixmap offset to the window position, in effect creating the
306same effect as pseudo transparency with a custom pixmap. No scaling is
307supported in this mode. Example:

324
325=item remote-clipboard
326
327Somewhat of a misnomer, this extension adds two menu entries to the
328selection popup that allows one ti run external commands to store the
329selection somewhere and fetch it again.
330
331We use it to implement a "distributed selection mechanism", which just
332means that one command uploads the file to a remote server, and another
333reads it.
334
335The commands can be set using the C<URxvt.remote-selection.store> and
336C<URxvt.remote-selection.fetch> resources. The first should read the
337selection to store from STDIN (always in UTF-8), the second should provide
338the selection data on STDOUT (also in UTF-8).
339
340The defaults (which are likely useless to you) use rsh and cat:
341
342 URxvt.remote-selection.store: rsh ruth 'cat >/tmp/distributed-selection'
343 URxvt.remote-selection.fetch: rsh ruth 'cat /tmp/distributed-selection'
344
345=item selection-pastebin
346
347This is a little rarely useful extension that Uploads the selection as
348textfile to a remote site (or does other things). (The implementation is
349not currently secure for use in a multiuser environment as it writes to
350F</tmp> directly.).
351
352It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
353i.e.
354
355 URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
356
357Pressing this combination runs a command with C<%> replaced by the name of
358the textfile. This command can be set via a resource:
359
360 URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
361
362And the default is likely not useful to anybody but the few people around
363here :)
364
365The name of the textfile is the hex encoded md5 sum of the selection, so
366the same content should lead to the same filename.
367
368After a successful upload the selection will be replaced by the text given
369in the C<selection-pastebin-url> resource (again, the % is the placeholder
370for the filename):
371
372 URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/%
373
374I<Note to xrdb users:> xrdb uses the C preprocessor, which might interpret
375the double C</> characters as comment start. Use C<\057\057> instead,
376which works regardless of wether xrdb is used to parse the resource file
377or not.
