52C<--quoting-style=shell>.
48 53
49It also offers the following bindable event: 54A double-click usually selects the word under the cursor, further clicks
55will enlarge the selection.
56
57The selection works by trying to match a number of regexes and displaying
58them in increasing order of length. You can add your own regexes by
59specifying resources of the form:
60
61 URxvt.selection.pattern-0: perl-regex
62 URxvt.selection.pattern-1: perl-regex
63 ...
64
65The index number (0, 1...) must not have any holes, and each regex must
66contain at least one pair of capturing parentheses, which will be used for
67the match. For example, the followign adds a regex that matches everything
68between two vertical bars:
69
70 URxvt.selection.pattern-0: \\|([^|]+)\\|
71
72Another example: Programs I use often output "absolute path: " at the
73beginning of a line when they process multiple files. The following
74pattern matches the filename (note, there is a single space at the very
75end):
76
77 URxvt.selection.pattern-0: ^(/[^:]+):\
78
79You can look at the source of the selection extension to see more
80interesting uses, such as parsing a line from beginning to end.

152was started, while C<Enter> or C<Return> stay at the current position and
153additionally stores the first match in the current line into the primary
154selection.
80 155
81Displays a digital clock using the built-in overlay. 156=item readline (enabled by default)
157
158A support package that tries to make editing with readline easier. At
159the moment, it reacts to clicking shift-left mouse button by trying to
160move the text cursor to this position. It does so by generating as many
161cursor-left or cursor-right keypresses as required (the this only works
162for programs that correctly support wide characters).
163
164To avoid too many false positives, this is only done when:
165
166=over 4
167
168=item - the tty is in ICANON state.
169
170=item - the text cursor is visible.
171
172=item - the primary screen is currently being displayed.
173
174=item - the mouse is on the same (multi-row-) line as the text cursor.
175
176=back
177
178The normal selection mechanism isn't disabled, so quick successive clicks
179might interfere with selection creation in harmless ways.
180
181=item selection-autotransform
182
183This selection allows you to do automatic transforms on a selection
184whenever a selection is made.
185
186It works by specifying perl snippets (most useful is a single C<s///>
187operator) that modify C<$_> as resources:
188
189 URxvt.selection-autotransform.0: transform
190 URxvt.selection-autotransform.1: transform
191 ...
192
193For example, the following will transform selections of the form
194C<filename:number>, often seen in compiler messages, into C<vi +$filename
195$word>:
196
197 URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/
198
199And this example matches the same,but replaces it with vi-commands you can
200paste directly into your (vi :) editor:
201
202 URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/
203
204Of course, this can be modified to suit your needs and your editor :)
205
206To expand the example above to typical perl error messages ("XXX at
207FILENAME line YYY."), you need a slightly more elaborate solution:
208
209 URxvt.selection.pattern-0: ( at .*? line \\d+[,.])
210 URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/
211
212The first line tells the selection code to treat the unchanging part of
213every error message as a selection pattern, and the second line transforms
214the message into vi commands to load the file.
215
216=item tabbed
217
218This transforms the terminal into a tabbar with additional terminals, that
219is, it implements what is commonly refered to as "tabbed terminal". The topmost line
220displays a "[NEW]" button, which, when clicked, will add a new tab, followed by one
221button per tab.
222
223Clicking a button will activate that tab. Pressing B<Shift-Left> and
224B<Shift-Right> will switch to the tab left or right of the current one,
225while B<Shift-Down> creates a new tab.
226
227The tabbar itself can be configured similarly to a normal terminal, but
228with a resource class of C<URxvt.tabbed>. In addition, it supports the
229following four resources (shown with defaults):
230
231 URxvt.tabbed.tabbar-fg: <colour-index, default 3>
232 URxvt.tabbed.tabbar-bg: <colour-index, default 0>
233 URxvt.tabbed.tab-fg: <colour-index, default 0>
234 URxvt.tabbed.tab-bg: <colour-index, default 1>
235
236See I<COLOR AND GRAPHICS> in the @@RXVT_NAME@@(1) manpage for valid
237indices.

85Uses per-line display filtering (C<on_line_update>) to underline urls. 241Uses per-line display filtering (C<on_line_update>) to underline urls and
242make them clickable. When middle-clicked, the program specified in the
243resource C<urlLauncher> (default C<x-www-browser>) will be started with
244the URL as first argument.
245
246=item xim-onthespot
247
248This (experimental) perl extension implements OnTheSpot editing. It does
249not work perfectly, and some input methods don't seem to work well with
250OnTheSpot editing in general, but it seems to work at leats for SCIM and
251kinput2.
252
253You enable it by specifying this extension and a preedit style of
254C<OnTheSpot>, i.e.:

258=item automove-background
259
260This is basically a one-line extension that dynamically changes the background pixmap offset
261to the window position, in effect creating the same effect as pseudo transparency with
262a custom pixmap. No scaling is supported in this mode. Exmaple:

272=item digital-clock
273
274Displays a digital clock using the built-in overlay.
275
276=item remote-clipboard
277
278Somewhat of a misnomer, this extension adds two menu entries to the
279selection popup that allows one ti run external commands to store the
280selection somewhere and fetch it again.
281
282We use it to implement a "distributed selection mechanism", which just
283means that one command uploads the file to a remote server, and another
284reads it.
285
286The commands can be set using the C<URxvt.remote-selection.store> and
287C<URxvt.remote-selection.fetch> resources. The first should read the
288selection to store from STDIN (always in UTF-8), the second should provide
289the selection data on STDOUT (also in UTF-8).
290
291The defaults (which are likely useless to you) use rsh and cat:
292
293 URxvt.remote-selection.store: rsh ruth 'cat >/tmp/distributed-selection'
294 URxvt.remote-selection.fetch: rsh ruth 'cat /tmp/distributed-selection'
295
296=item selection-pastebin
297
298This is a little rarely useful extension that Uploads the selection as
299textfile to a remote site (or does other things). (The implementation is
300not currently secure for use in a multiuser environment as it writes to
301F</tmp> directly.).
302
303It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
304i.e.
305
306 URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
307
308Pressing this combination runs a command with C<%> replaced by the name of
309the textfile. This command can be set via a resource:
310
311 URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
312
313And the default is likely not useful to anybody but the few people around
314here :)
315
316The name of the textfile is the hex encoded md5 sum of the selection, so
317the same content should lead to the same filename.
318
319After a successful upload the selection will be replaced by the text given
320in the C<selection-pastebin-url> resource (again, the % is the placeholder
321for the filename):
322
323 URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/%

356
357=item $term = new urxvt [arg...]
358
359Creates a new terminal, very similar as if you had started it with
360C<system $binfile, arg...>. Croaks (and probably outputs an error message)
361if the new instance couldn't be created. Returns C<undef> if the new
362instance didn't initialise perl, and the terminal object otherwise. The
363C<init> and C<start> hooks will be called during the call.
364
365=item urxvt::fatal $errormessage
366
367Fatally aborts execution with the given error message. Avoid at all
368costs! The only time this is acceptable is when the terminal process
369starts up.
370
371=item urxvt::warn $string
372
373Calls C<rxvt_warn> with the given string which should not include a
374newline. The module also overwrites the C<warn> builtin with a function
375that calls this function.
376
377Using this function has the advantage that its output ends up in the
378correct place, e.g. on stderr of the connecting urxvtc client.
379
380=item $is_safe = urxvt::safe
381
382Returns true when it is safe to do potentially unsafe things, such as
383evaluating perl code specified by the user. This is true when urxvt was
384started setuid or setgid.
385
386=item $time = urxvt::NOW

420
421=item $rendbit = urxvt::RS_Bold, RS_Italic, RS_Blink, RS_RVid, RS_Uline
422
423Return the bit that enabled bold, italic, blink, reverse-video and
424underline, respectively. To enable such a style, just logically OR it into
425the bitset.
426
427=item $foreground = urxvt::GET_BASEFG $rend

438specified one.
439
440=item $value = urxvt::GET_CUSTOM ($rend)
441
442Return the "custom" value: Every rendition has 5 bits for use by
443extensions. They can be set and changed as you like and are initially
444zero.

682gets cleared before the codereferences that were in it are being executed,
683so coderefs can push themselves onto it again if they so desire.
684
685This complements to the perl-eval commandline option, but gets executed
686first.
687
688=item @urxvt::TERM_EXT
689
690Works similar to C<@TERM_INIT>, but contains perl package/class names, which
