		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

		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

		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	operating system command) is processed. Cursor position and other state
		214	information is up-to-date when this happens. For interoperability, the

		219	Be careful not ever to trust (in a security sense) the data you receive,

		222
		223	=item on_add_lines $term, $string
		224
		225	Called whenever text is about to be output, with the text as argument. You
		226	can filter/change and output the text yourself by returning a true value
		227	and calling C<< $term->scr_add_lines >> yourself. Please note that this
		228	might be very slow, however, as your hook is called for B<all> text being
		229	output.
		230
		231	=item on_line_update $term, $row
		232
		233	Called whenever a line was updated or changed. Can be used to filter
		234	screen output (e.g. underline urls or other useless stuff). Only lines
		235	that are being shown will be filtered, and, due to performance reasons,
		236	not always immediately.
		237
		238	The row number is always the topmost row of the line if the line spans
		239	multiple rows.
		240
		241	Please note that, if you change the line, then the hook might get called
		242	later with the already-modified line (e.g. if unrelated parts change), so
		243	you cannot just toggle rendition bits, but only set them.
