		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:
		37

		39
		40	=over 4
		41
		42	=item selection (enabled by default)
		43
		44	Intelligent selection. This extension tries to be more intelligent when
		45	the user extends selections (double-click). Right now, it tries to select
		46	urls and complete shell-quoted arguments, which is very convenient, too,
		47	if your F<ls> supports C<--quoting-style=shell>.
		48
		49	It also offers the following bindable event:
		50
		51	=over 4
		52
		53	=item rot13
		54
		55	Rot-13 the selection when activated. Used via keyboard trigger:

		58
		59	=back
		60
		61	=item option-popup (enabled by default)
		62
		63	Binds a popup menu to Ctrl-Button2 that lets you toggle (some) options at
		64	runtime.
		65
		66	=item selection-popup (enabled by default)
		67
		68	Binds a popup menu to Ctrl-Button3 that lets you convert the selection
		69	text into various other formats/action.
		70
		71	=item digital-clock
		72
		73	Displays a digital clock using the built-in overlay.
		74
		75	=item mark-urls
		76
		77	Uses per-line display filtering (C<on_line_update>) to underline urls.
		78
		79	=item block-graphics-to-ascii
		80
		81	A not very useful example of filtering all text output to the terminal,
		82	by replacing all line-drawing characters (U+2500 .. U+259F) by a
		83	similar-looking ascii character.
		84
		85	=item example-refresh-hooks

		112
		113	Rxvt-unicodes special way of encoding text, where one "unicode" character
		114	always represents one screen cell. See L<row_t> for a discussion of this format.
		115
		116	=item $string
		117
		118	A perl text string, with an emphasis on I<text>. It can store all unicode
		119	characters and is to be distinguished with text encoded in a specific
		120	encoding (often locale-specific) and binary data.
		121

		134	The first argument passed to them is an object private to each terminal

		137	object that is shared between all packages is stored in the C<term>
		138	member. It is, however, blessed intot he package of the extension script,
		139	so for all practical purposes you can treat an extension script as a class.

		213
		214	=item on_osc_seq $term, $string
		215
		216	Called whenever the B<ESC ] 777 ; string ST> command sequence (OSC =
		217	operating system command) is processed. Cursor position and other state
		218	information is up-to-date when this happens. For interoperability, the
		219	string should start with the extension name and a colon, to distinguish
		220	it from commands for other extensions, and this might be enforced in the
		221	future.
		222
		223	Be careful not ever to trust (in a security sense) the data you receive,
		224	as its source can not easily be controleld (e-mail content, messages from
		225	other users on the same system etc.).
		226
		227	=item on_add_lines $term, $string
		228
		229	Called whenever text is about to be output, with the text as argument. You
		230	can filter/change and output the text yourself by returning a true value
		231	and calling C<< $term->scr_add_lines >> yourself. Please note that this
		232	might be very slow, however, as your hook is called for B<all> text being
		233	output.
		234
		235	=item on_line_update $term, $row
		236
		237	Called whenever a line was updated or changed. Can be used to filter
		238	screen output (e.g. underline urls or other useless stuff). Only lines
		239	that are being shown will be filtered, and, due to performance reasons,
		240	not always immediately.
		241
		242	The row number is always the topmost row of the line if the line spans
		243	multiple rows.
		244
		245	Please note that, if you change the line, then the hook might get called
		246	later with the already-modified line (e.g. if unrelated parts change), so
		247	you cannot just toggle rendition bits, but only set them.

		936
		937	Requests a screen refresh. At the next opportunity, rxvt-unicode will
		938	compare the on-screen display with its stored representation. If they
		939	differ, it redraws the differences.
		940
		941	Used after changing terminal contents to display them.
		942
		943	=item $text = $term->ROW_t ($row_number[, $new_text[, $start_col]])
		944
		945	Returns the text of the entire row with number C<$row_number>. Row C<0>
		946	is the topmost terminal line, row C<< $term->$ncol-1 >> is the bottommost
		947	terminal line. The scrollback buffer starts at line C<-1> and extends to
		948	line C<< -$term->nsaved >>. Nothing will be returned if a nonexistent line
		949	is requested.
		950
		951	If C<$new_text> is specified, it will replace characters in the current
		952	line, starting at column C<$start_col> (default C<0>), which is useful
		953	to replace only parts of a line. The font index in the rendition will
		954	automatically be updated.
		955
		956	C<$text> is in a special encoding: tabs and wide characters that use more
		957	than one cell when displayed are padded with urxvt::NOCHAR characters
		958	(C<chr 65535>). Characters with combining characters and other characters
		959	that do not fit into the normal tetx encoding will be replaced with
		960	characters in the private use area.
		961
		962	You have to obey this encoding when changing text. The advantage is
		963	that C<substr> and similar functions work on screen cells and not on
		964	characters.
		965
		966	The methods C<< $term->special_encode >> and C<< $term->special_decode >>
		967	can be used to convert normal strings into this encoding and vice versa.
		968
		969	=item $rend = $term->ROW_r ($row_number[, $new_rend[, $start_col]])
		970
		971	Like C<< $term->ROW_t >>, but returns an arrayref with rendition
		972	bitsets. Rendition bitsets contain information about colour, font, font
		973	styles and similar information. See also C<< $term->ROW_t >>.
		974
		975	When setting rendition, the font mask will be ignored.
		976
		977	See the section on RENDITION, above.
		978
		979	=item $length = $term->ROW_l ($row_number[, $new_length])
		980
		981	Returns the number of screen cells that are in use ("the line
		982	length"). Unlike the urxvt core, this returns C<< $term->ncol >> if the
		983	line is joined with the following one.
		984
		985	=item $bool = $term->is_longer ($row_number)
		986
		987	Returns true if the row is part of a multiple-row logical "line" (i.e.
		988	joined with the following row), which means all characters are in use
		989	and it is continued on the next row (and possibly a continuation of the
		990	previous row(s)).
		991
		992	=item $line = $term->line ($row_number)
		993
		994	Create and return a new C<urxvt::line> object that stores information
		995	about the logical line that row C<$row_number> is part of. It supports the
		996	following methods:
		997
		998	=over 4
		999
		1000	=item $text = $line->t ([$new_text])
		1001
		1002	Returns or replaces the full text of the line, similar to C<ROW_t>
		1003
		1004	=item $rend = $line->r ([$new_rend])
		1005
		1006	Returns or replaces the full rendition array of the line, similar to C<ROW_r>
		1007
		1008	=item $length = $line->l
		1009
		1010	Returns the length of the line in cells, similar to C<ROW_l>.
		1011
		1012	=item $rownum = $line->beg
		1013
		1014	=item $rownum = $line->end
		1015
		1016	Return the row number of the first/last row of the line, respectively.
		1017
		1018	=item $offset = $line->offset_of ($row, $col)
		1019
		1020	Returns the character offset of the given row\|col pair within the logical
		1021	line.
		1022
		1023	=item ($row, $col) = $line->coord_of ($offset)
		1024
		1025	Translates a string offset into terminal coordinates again.
