		21
		22	Everytime a terminal object gets created, scripts specified via the
		23	C<perl> resource are loaded and associated with it.
		24
		25	Scripts are compiled in a 'use strict' and 'use utf8' environment, and
		26	thus must be encoded as UTF-8.
		27
		28	Each script will only ever be loaded once, even in @@RXVT_NAME@@d, where
		29	scripts will be shared (but not enabled) for all terminals.

		31	=head2 Prepackaged Extensions
		32
		33	This section describes the extensiosn delivered with this version. You can
		34	find them in F<@@RXVT_LIBDIR@@/urxvt/perl/>.
		35
		36	You can activate them like this:

		41
		42	=item selection
		43
		44	Intelligent selection. This etxension tries to be more intelligent when the user
		45	extends selections (double-click).
		46
		47	It also offers the following bindable event:

		59	=item digital-clock
		60
		61	Displays a digital clock using the built-in overlay.
		62
		63	=item example-refresh-hooks
		64
		65	Displays a very simple digital clock in the upper right corner of the
		66	window. Illustrates overwriting the refresh callbacks to create your own
		67	overlays or changes.

		70
		71	=head2 General API Considerations
		72
		73	All objects (such as terminals, time watchers etc.) are typical
		74	reference-to-hash objects. The hash can be used to store anything you
		75	like. All members starting with an underscore (such as C<_ptr> or
		76	C<_hook>) are reserved for internal uses and must not be accessed or
		77	modified).
		78
		79	When objects are destroyed on the C++ side, the perl object hashes are
		80	emptied, so its best to store related objects such as time watchers and
		81	the like inside the terminal object so they get destroyed as soon as the
		82	terminal is destroyed.

		501	accounts for wide and combining characters.
		502
		503	=item $octets = $term->locale_encode $string
		504
		505	Convert the given text string into the corresponding locale encoding.
		506
		507	=item $string = $term->locale_decode $octets
		508
		509	Convert the given locale-encoded octets into a perl string.
		510
		511	=item $term->tt_write ($octets)
		512
		513	Write the octets given in C<$data> to the tty (i.e. as program input). To
		514	pass characters instead of octets, you should convert your strings first
		515	to the locale-specific encoding using C<< $term->locale_encode >>.
		516
		517	=item $nrow = $term->nrow
		518
		519	=item $ncol = $term->ncol
		520
		521	Return the number of rows/columns of the terminal window (i.e. as
		522	specified by C<-geometry>, excluding any scrollback).
		523
		524	=item $nsaved = $term->nsaved
		525
		526	Returns the number of lines in the scrollback buffer.
		527
		528	=item $view_start = $term->view_start ([$newvalue])
		529
		530	Returns the negative row number of the topmost line. Minimum value is
		531	C<0>, which displays the normal terminal contents. Larger values scroll
		532	this many lines into the scrollback buffer.
		533
		534	=item $term->want_refresh
		535
		536	Requests a screen refresh. At the next opportunity, rxvt-unicode will
		537	compare the on-screen display with its stored representation. If they
		538	differ, it redraws the differences.
		539
		540	Used after changing terminal contents to display them.
		541
		542	=item $text = $term->ROW_t ($row_number[, $new_text[, $start_col]])
		543
		544	Returns the text of the entire row with number C<$row_number>. Row C<0>
		545	is the topmost terminal line, row C<< $term->$ncol-1 >> is the bottommost
		546	terminal line. The scrollback buffer starts at line C<-1> and extends to
		547	line C<< -$term->nsaved >>.
		548
		549	If C<$new_text> is specified, it will replace characters in the current
		550	line, starting at column C<$start_col> (default C<0>), which is useful
		551	to replace only parts of a line. The font index in the rendition will
		552	automatically be updated.
		553
		554	C<$text> is in a special encoding: tabs and wide characters that use more
		555	than one cell when displayed are padded with urxvt::NOCHAR characters
		556	(C<chr 65535>). Characters with combining characters and other characters
		557	that do not fit into the normal tetx encoding will be replaced with
		558	characters in the private use area.
		559
		560	You have to obey this encoding when changing text. The advantage is
		561	that C<substr> and similar functions work on screen cells and not on
		562	characters.
		563
		564	The methods C<< $term->special_encode >> and C<< $term->special_decode >>
		565	can be used to convert normal strings into this encoding and vice versa.
		566
		567	=item $rend = $term->ROW_r ($row_number[, $new_rend[, $start_col]])
		568
		569	Like C<< $term->ROW_t >>, but returns an arrayref with rendition
		570	bitsets. Rendition bitsets contain information about colour, font, font
		571	styles and similar information. See also C<< $term->ROW_t >>.
		572
		573	When setting rendition, the font mask will be ignored.
		574
		575	See the section on RENDITION, above.
		576
		577	=item $length = $term->ROW_l ($row_number[, $new_length])
		578
		579	Returns the number of screen cells that are in use ("the line length"). If
		580	it is C<-1>, then the line is part of a multiple-row logical "line", which
		581	means all characters are in use and it is continued on the next row.
		582
		583	=item $text = $term->special_encode $string
		584
		585	Converts a perl string into the special encoding used by rxvt-unicode,
		586	where one character corresponds to one screen cell. See
		587	C<< $term->ROW_t >> for details.
		588
		589	=item $string = $term->special_decode $text
		590
		591	Converts rxvt-unicodes text reprsentation into a perl string. See
		592	C<< $term->ROW_t >> for details.
