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

		104
		105	Other extensions can extend this popup menu by pushing a code reference
		106	onto C<@{ $term->{selection_popup_hook} }>, that is called whenever the
		107	popup is displayed.
		108
		109	It's sole argument is the popup menu, which can be modified. The selection
		110	is in C<$_>, which can be used to decide wether to add something or not.
		111	It should either return nothing or a string and a code reference. The
		112	string will be used as button text and the code reference will be called
		113	when the button gets activated and should transform C<$_>.
		114
		115	The following will add an entry C<a to b> that transforms all C<a>s in
		116	the selection to C<b>s, but only if the selection currently contains any
		117	C<a>s:
		118
		119	push @{ $self->{term}{selection_popup_hook} }, sub {

		137	selection.

83	=item digital-clock	139	=item readline (enabled by default)
84		140
85	Displays a digital clock using the built-in overlay.	141	A support package that tries to make editing with readline easier. At the
		142	moment, it reacts to clicking with the left mouse button by trying to
		143	move the text cursor to this position. It does so by generating as many
		144	cursor-left or cursor-right keypresses as required (the this only works
		145	for programs that correctly support wide characters).
		146
		147	To avoid too many false positives, this is only done when:
		148
		149	=over 4
		150
		151	=item - the tty is in ICANON state.
		152
		153	=item - the text cursor is visible.
		154
		155	=item - the primary screen is currently being displayed.
		156
		157	=item - the mouse is on the same (multi-row-) line as the text cursor.
		158
		159	=back
		160
		161	The normal selection mechanism isn't disabled, so quick successive clicks
		162	might interfere with selection creation in harmless ways.
		163
		164	=item selection-autotransform
		165
		166	This selection allows you to do automatic transforms on a selection
		167	whenever a selection is made.
		168
		169	It works by specifying perl snippets (most useful is a single C<s///>
		170	operator) that modify C<$_> as resources:
		171
		172	URxvt.selection-autotransform.0: transform
		173	URxvt.selection-autotransform.1: transform
		174	...
		175
		176	For example, the following will transform selections of the form
		177	C<filename:number>, often seen in compiler messages, into C<vi +$filename
		178	$word>:
		179
		180	URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/
		181
		182	And this example matches the same,but replaces it with vi-commands you can
		183	paste directly into your (vi :) editor:
		184
		185	URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/
		186
		187	Of course, this can be modified to suit your needs and your editor :)
		188
		189	To expand the example above to typical perl error messages ("XXX at
		190	FILENAME line YYY."), you need a slightly more elaborate solution:
		191
		192	URxvt.selection.pattern-0: ( at .*? line \\d+[,.])
		193	URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/
		194
		195	The first line tells the selection code to treat the unchanging part of
		196	every error message as a selection pattern, and the second line transforms
		197	the message into vi commands to load the file.
		198
		199	=item tabbed
		200
		201	This transforms the terminal into a tabbar with additional terminals, that
		202	is, it implements what is commonly refered to as "tabbed terminal". The topmost line
		203	displays a "[NEW]" button, which, when clicked, will add a new tab, followed by one
		204	button per tab.
		205
		206	Clicking a button will activate that tab. Pressing B<Shift-Left> and
		207	B<Shift-Right> will switch to the tab left or right of the current one,
		208	while B<Shift-Down> creates a new tab.
86		209
87	=item mark-urls	210	=item mark-urls
88		211
89	Uses per-line display filtering (C<on_line_update>) to underline urls.	212	Uses per-line display filtering (C<on_line_update>) to underline urls and
		213	make them clickable. When middle-clicked, the program specified in the
		214	resource C<urlLauncher> (default C<x-www-browser>) will be started with
		215	the URL as first argument.
		216
		217	=item xim-onthespot
		218
		219	This (experimental) perl extension implements OnTheSpot editing. It does
		220	not work perfectly, and some input methods don't seem to work well with
		221	OnTheSpot editing in general, but it seems to work at leats for SCIM and
		222	kinput2.
		223
		224	You enable it by specifying this extension and a preedit style of
		225	C<OnTheSpot>, i.e.:
		226
		227	@@RXVT_NAME@@ -pt OnTheSpot -pe xim-onthespot
		228
		229	=item automove-background
		230
		231	This is basically a one-line extension that dynamically changes the background pixmap offset
		232	to the window position, in effect creating the same effect as pseudo transparency with
		233	a custom pixmap. No scaling is supported in this mode. Exmaple:
		234
		235	@@RXVT_NAME@@ -pixmap background.xpm -pe automove-background

		242
		243	=item digital-clock
		244
		245	Displays a digital clock using the built-in overlay.
		246
		247	=item remote-clipboard
		248
		249	Somewhat of a misnomer, this extension adds two menu entries to the
		250	selection popup that allows one ti run external commands to store the
		251	selection somewhere and fetch it again.
		252
		253	We use it to implement a "distributed selection mechanism", which just
		254	means that one command uploads the file to a remote server, and another
		255	reads it.
		256
		257	The commands can be set using the C<URxvt.remote-selection.store> and
		258	C<URxvt.remote-selection.fetch> resources. The first should read the
		259	selection to store from STDIN (always in UTF-8), the second should provide
		260	the selection data on STDOUT (also in UTF-8).
		261
		262	The defaults (which are likely useless to you) use rsh and cat:
		263
		264	URxvt.remote-selection.store: rsh ruth 'cat >/tmp/distributed-selection'
		265	URxvt.remote-selection.fetch: rsh ruth 'cat /tmp/distributed-selection'
		266
		267	=item selection-pastebin
		268
		269	This is a little rarely useful extension that Uploads the selection as
		270	textfile to a remote site (or does other things). (The implementation is
		271	not currently secure for use in a multiuser environment as it writes to
		272	F</tmp> directly.).
		273
		274	It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
		275	i.e.
		276
		277	URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
		278
		279	Pressing this combination runs a command with C<%> replaced by the name of
		280	the textfile. This command can be set via a resource:
		281
		282	URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
		283
		284	And the default is likely not useful to anybody but the few people around
		285	here :)
		286
		287	The name of the textfile is the hex encoded md5 sum of the selection, so
		288	the same content should lead to the same filename.
		289
		290	After a successful upload the selection will be replaced by the text given
		291	in the C<selection-pastebin-url> resource (again, the % is the placeholder
		292	for the filename):
		293
		294	URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/%

377
378	=item $term = new urxvt [arg...]
379
380	Creates a new terminal, very similar as if you had started it with
381	C<system $binfile, arg...>. Croaks (and probably outputs an error message)
382	if the new instance couldn't be created. Returns C<undef> if the new
383	instance didn't initialise perl, and the terminal object otherwise. The
384	C<init> and C<start> hooks will be called during the call.
385
386	=item urxvt::fatal $errormessage
387
388	Fatally aborts execution with the given error message. Avoid at all
389	costs! The only time this is acceptable is when the terminal process
390	starts up.
391
392	=item urxvt::warn $string
393
394	Calls C<rxvt_warn> with the given string which should not include a
395	newline. The module also overwrites the C<warn> builtin with a function
396	that calls this function.
397
398	Using this function has the advantage that its output ends up in the
399	correct place, e.g. on stderr of the connecting urxvtc client.
400
401	=item $is_safe = urxvt::safe
402
403	Returns true when it is safe to do potentially unsafe things, such as
404	evaluating perl code specified by the user. This is true when urxvt was
405	started setuid or setgid.
406
407	=item $time = urxvt::NOW

422
423	Rendition bitsets contain information about colour, font, font styles and
424	similar information for each screen cell.
425
426	The following "macros" deal with changes in rendition sets. You should
427	never just create a bitset, you should always modify an existing one,
428	as they contain important information required for correct operation of
429	rxvt-unicode.
430

432
433	=item $rend = urxvt::DEFAULT_RSTYLE
434
435	Returns the default rendition, as used when the terminal is starting up or
436	being reset. Useful as a base to start when creating renditions.
437
438	=item $rend = urxvt::OVERLAY_RSTYLE
439
440	Return the rendition mask used for overlays by default.
441
442	=item $rendbit = urxvt::RS_Bold, RS_Italic, RS_Blink, RS_RVid, RS_Uline
443
444	Return the bit that enabled bold, italic, blink, reverse-video and
445	underline, respectively. To enable such a style, just logically OR it into
446	the bitset.
447
448	=item $foreground = urxvt::GET_BASEFG $rend
449
450	=item $background = urxvt::GET_BASEBG $rend

455
456	=item $rend = urxvt::SET_BGCOLOR $rend, $new_colour

459	specified one.
460
461	=item $value = urxvt::GET_CUSTOM $rend
462
463	Return the "custom" value: Every rendition has 5 bits for use by
464	extensions. They can be set and changed as you like and are initially
465	zero.
466
467	=item $rend = urxvt::SET_CUSTOM $rend, $new_value
