165=item readline (enabled by default)
166
167A support package that tries to make editing with readline easier. At
168the moment, it reacts to clicking shift-left mouse button by trying to
169move the text cursor to this position. It does so by generating as many
170cursor-left or cursor-right keypresses as required (this only works
171for programs that correctly support wide characters).
172
173To avoid too many false positives, this is only done when:
174
175=over 4
176
177=item - the tty is in ICANON state.
178
179=item - the text cursor is visible.
180
181=item - the primary screen is currently being displayed.
182
183=item - the mouse is on the same (multi-row-) line as the text cursor.

187The normal selection mechanism isn't disabled, so quick successive clicks
188might interfere with selection creation in harmless ways.

161=item mark-urls 225=item tabbed
162 226
227This transforms the terminal into a tabbar with additional terminals, that
228is, it implements what is commonly referred to as "tabbed terminal". The topmost line
229displays a "[NEW]" button, which, when clicked, will add a new tab, followed by one
230button per tab.
231
232Clicking a button will activate that tab. Pressing B<Shift-Left> and
233B<Shift-Right> will switch to the tab left or right of the current one,
234while B<Shift-Down> creates a new tab.
235
236The tabbar itself can be configured similarly to a normal terminal, but
237with a resource class of C<URxvt.tabbed>. In addition, it supports the
238following four resources (shown with defaults):
239
240 URxvt.tabbed.tabbar-fg: <colour-index, default 3>
241 URxvt.tabbed.tabbar-bg: <colour-index, default 0>
242 URxvt.tabbed.tab-fg: <colour-index, default 0>
243 URxvt.tabbed.tab-bg: <colour-index, default 1>

246indices.

166the URL as first argument. 253middle), the program specified in the C<matcher.launcher> resource
254(default, the C<urlLauncher> resource, C<sensible-browser>) will be started
255with the matched text as first argument. The default configuration is
256suitable for matching URLs and launching a web browser, like the
257former "mark-urls" extension.
258
259The default pattern to match URLs can be overridden with the
260C<matcher.pattern.0> resource, and additional patterns can be specified
261with numbered patterns, in a manner similar to the "selection" extension.
262The launcher can also be overridden on a per-pattern basis.
263
264It is possible to activate the most recently seen match or a list of matches
265from the keyboard. Simply bind a keysym to "perl:matcher:last" or
266"perl:matcher:list" as seen in the example below.
267
268Example configuration:
269
270 URxvt.perl-ext: default,matcher
271 URxvt.urlLauncher: sensible-browser
272 URxvt.keysym.C-Delete: perl:matcher:last
273 URxvt.keysym.M-Delete: perl:matcher:list
274 URxvt.matcher.button: 1
275 URxvt.matcher.pattern.1: \\bwww\\.[\\w-]+\\.[\\w./?&@#-]*[\\w/-]

277 URxvt.matcher.launcher.2: gvim +$2 $1

279=item xim-onthespot
280
281This (experimental) perl extension implements OnTheSpot editing. It does
282not work perfectly, and some input methods don't seem to work well with
283OnTheSpot editing in general, but it seems to work at least for SCIM and
284kinput2.
285
286You enable it by specifying this extension and a preedit style of
287C<OnTheSpot>, i.e.:

290
291=item kuake<hotkey>
292
293A very primitive quake-console-like extension. It was inspired by a
294description of how the programs C<kuake> and C<yakuake> work: Whenever the
295user presses a global accelerator key (by default C<F10>), the terminal
296will show or hide itself. Another press of the accelerator key will hide
297or show it again.
298
299Initially, the window will not be shown when using this extension.
300
301This is useful if you need a single terminal that is not using any desktop
302space most of the time but is quickly available at the press of a key.
303
304The accelerator key is grabbed regardless of any modifiers, so this
305extension will actually grab a physical key just for this function.
306
307If you want a quake-like animation, tell your window manager to do so
308(fvwm can do it).
309
310=item overlay-osc
311
312This extension implements some OSC commands to display timed popups on the
313screen - useful for status displays from within scripts. You have to read
314the sources for more info.

325
326=item remote-clipboard
327
328Somewhat of a misnomer, this extension adds two menu entries to the
329selection popup that allows one to run external commands to store the
330selection somewhere and fetch it again.
331
332We use it to implement a "distributed selection mechanism", which just
333means that one command uploads the file to a remote server, and another
334reads it.
335
336The commands can be set using the C<URxvt.remote-selection.store> and
337C<URxvt.remote-selection.fetch> resources. The first should read the
338selection to store from STDIN (always in UTF-8), the second should provide
339the selection data on STDOUT (also in UTF-8).
340
341The defaults (which are likely useless to you) use rsh and cat:
342
343 URxvt.remote-selection.store: rsh ruth 'cat >/tmp/distributed-selection'
344 URxvt.remote-selection.fetch: rsh ruth 'cat /tmp/distributed-selection'
345
346=item selection-pastebin
347
348This is a little rarely useful extension that uploads the selection as
349textfile to a remote site (or does other things). (The implementation is
350not currently secure for use in a multiuser environment as it writes to
351F</tmp> directly.).
352
353It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
354i.e.
355
356 URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
357
358Pressing this combination runs a command with C<%> replaced by the name of
359the textfile. This command can be set via a resource:
360
361 URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
362
363And the default is likely not useful to anybody but the few people around
364here :)
365
366The name of the textfile is the hex encoded md5 sum of the selection, so
367the same content should lead to the same filename.
368
369After a successful upload the selection will be replaced by the text given
370in the C<selection-pastebin-url> resource (again, the % is the placeholder
371for the filename):
372
373 URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/%
374
375I<Note to xrdb users:> xrdb uses the C preprocessor, which might interpret
376the double C</> characters as comment start. Use C<\057\057> instead,
377which works regardless of whether xrdb is used to parse the resource file
378or not.
379
380=item macosx-clipboard and macosx-clipboard-native
381
382These two modules implement an extended clipboard for Mac OS X. They are
383used like this:
384
385 URxvt.perl-ext-common: default,macosx-clipboard
386 URxvt.keysym.M-c: perl:macosx-clipboard:copy
387 URxvt.keysym.M-v: perl:macosx-clipboard:paste
388
389The difference between them is that the native variant requires a
390perl from apple's devkit or so, and C<macosx-clipboard> requires the
391C<Mac::Pasteboard> module, works with other perls, has fewer bugs, is
392simpler etc. etc.
