52 59
60The selection works by trying to match a number of regexes and displaying
61them in increasing order of length. You can add your own regexes by
62specifying resources of the form:
63
64 URxvt.selection.pattern-0: perl-regex
65 URxvt.selection.pattern-1: perl-regex
66 ...
67
68The index number (0, 1...) must not have any holes, and each regex must
69contain at least one pair of capturing parentheses, which will be used for
70the match. For example, the following adds a regex that matches everything
71between two vertical bars:
72
73 URxvt.selection.pattern-0: \\|([^|]+)\\|
74
75Another example: Programs I use often output "absolute path: " at the
76beginning of a line when they process multiple files. The following
77pattern matches the filename (note, there is a single space at the very
78end):
79
80 URxvt.selection.pattern-0: ^(/[^:]+):\

82You can look at the source of the selection extension to see more
83interesting uses, such as parsing a line from beginning to end.

161or simply use an uppercase character which removes the "(?i)" prefix.

94 164
95=item mark-urls 165=item readline (enabled by default)
96 166
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.
184
185=back
186
187The normal selection mechanism isn't disabled, so quick successive clicks
188might interfere with selection creation in harmless ways.
189
190=item selection-autotransform
191
192This selection allows you to do automatic transforms on a selection
193whenever a selection is made.
194
195It works by specifying perl snippets (most useful is a single C<s///>
196operator) that modify C<$_> as resources:
197
198 URxvt.selection-autotransform.0: transform
199 URxvt.selection-autotransform.1: transform
200 ...
201
202For example, the following will transform selections of the form
203C<filename:number>, often seen in compiler messages, into C<vi +$filename
204$word>:
205
206 URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/
207
208And this example matches the same,but replaces it with vi-commands you can
209paste directly into your (vi :) editor:
210
211 URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/
212
213Of course, this can be modified to suit your needs and your editor :)
214
215To expand the example above to typical perl error messages ("XXX at
216FILENAME line YYY."), you need a slightly more elaborate solution:
217
218 URxvt.selection.pattern-0: ( at .*? line \\d+[,.])
219 URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/
220
221The first line tells the selection code to treat the unchanging part of
222every error message as a selection pattern, and the second line transforms
223the message into vi commands to load the file.
224
225=item tabbed
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>
244
245See I<COLOR AND GRAPHICS> in the @@RXVT_NAME@@(1) manpage for valid
246indices.

98make them clickable. When middle-clicked, the program specified in the 251matching a certain pattern and make it clickable. When clicked with the
99resource C<urlLauncher> (default C<x-www-browser>) will be started with 252mouse button specified in the C<matcher.button> resource (default 2, or
100the 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 from the keyboard.
265Simply bind a keysym to "perl:matcher" as seen in the example below.
266
267Example configuration:
268
269 URxvt.perl-ext: default,matcher
270 URxvt.urlLauncher: sensible-browser
271 URxvt.keysym.C-Delete: perl:matcher
272 URxvt.matcher.button: 1
273 URxvt.matcher.pattern.1: \\bwww\\.[\\w-]+\\.[\\w./?&@#-]*[\\w/-]

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

277=item xim-onthespot
278
279This (experimental) perl extension implements OnTheSpot editing. It does
280not work perfectly, and some input methods don't seem to work well with
281OnTheSpot editing in general, but it seems to work at least for SCIM and
282kinput2.
283
284You enable it by specifying this extension and a preedit style of
285C<OnTheSpot>, i.e.:

288
289=item kuake<hotkey>
290
291A very primitive quake-console-like extension. It was inspired by a
292description of how the programs C<kuake> and C<yakuake> work: Whenever the
293user presses a global accelerator key (by default C<F10>), the terminal
294will show or hide itself. Another press of the accelerator key will hide
295or show it again.
296
297Initially, the window will not be shown when using this extension.
298
299This is useful if you need a single terminal that is not using any desktop
300space most of the time but is quickly available at the press of a key.
301
302The accelerator key is grabbed regardless of any modifiers, so this
303extension will actually grab a physical key just for this function.
304
305If you want a quake-like animation, tell your window manager to do so
306(fvwm can do it).
307
308=item overlay-osc
309
310This extension implements some OSC commands to display timed popups on the
311screen - useful for status displays from within scripts. You have to read
312the sources for more info.

319
320=item digital-clock
321
322Displays a digital clock using the built-in overlay.
323
324=item remote-clipboard
325
326Somewhat of a misnomer, this extension adds two menu entries to the
327selection popup that allows one to run external commands to store the
328selection somewhere and fetch it again.
329
330We use it to implement a "distributed selection mechanism", which just
331means that one command uploads the file to a remote server, and another
332reads it.
333
334The commands can be set using the C<URxvt.remote-selection.store> and
335C<URxvt.remote-selection.fetch> resources. The first should read the
336selection to store from STDIN (always in UTF-8), the second should provide
337the selection data on STDOUT (also in UTF-8).
338
339The defaults (which are likely useless to you) use rsh and cat:
340
341 URxvt.remote-selection.store: rsh ruth 'cat >/tmp/distributed-selection'
342 URxvt.remote-selection.fetch: rsh ruth 'cat /tmp/distributed-selection'
343
344=item selection-pastebin
345
346This is a little rarely useful extension that Uploads the selection as
347textfile to a remote site (or does other things). (The implementation is
348not currently secure for use in a multiuser environment as it writes to
349F</tmp> directly.).
350
351It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
352i.e.
353
354 URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
355
356Pressing this combination runs a command with C<%> replaced by the name of
357the textfile. This command can be set via a resource:
358
359 URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
360
361And the default is likely not useful to anybody but the few people around
362here :)
363
364The name of the textfile is the hex encoded md5 sum of the selection, so
365the same content should lead to the same filename.
366
367After a successful upload the selection will be replaced by the text given
368in the C<selection-pastebin-url> resource (again, the % is the placeholder
369for the filename):
370
371 URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/%
372
373I<Note to xrdb users:> xrdb uses the C preprocessor, which might interpret
374the double C</> characters as comment start. Use C<\057\057> instead,
375which works regardless of wether xrdb is used to parse the resource file
376or not.
377
378=item macosx-pastebin and macosx-pastebin-native
379
380These two modules implement an extended clipboard for Mac OS X. They are
381used like this:
382
383 URxvt.perl-ext-common: default,macosx-clipboard
384 URxvt.keysym.M-c: perl:macosx-clipboard:copy
385 URxvt.keysym.M-v: perl:macosx-clipboard:paste
386
387The difference between them is that the native variant requires a
388perl from apple's devkit or so, and C<maxosx-pastebin> requires the
389C<Mac::Pasteboard> module, works with other perls, has fewer bugs, is
390simpler etc. etc.
