30	terminals created with that specific option value.	32
		33	This section describes the extensiosn delivered with this version. You can
		34	find them in F<@@RXVT_LIBDIR@@/urxvt/perl/>.

		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:

		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.

		73	Displays a digital clock using the built-in overlay.

		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.

		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.

		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,

		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

		222
		223	Be careful not ever to trust (in a security sense) the data you receive,

		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.

		913
		914	=item $lines_in_scrollback = $term->nsaved

		917

		919
		920	=item $modifiermask = $term->ModMetaMask
		921
		922	=item $modifiermask = $term->ModNumLockMask
		923
		924	Return the modifier masks corresponding to the "ISO Level 3 Shift" (often
		925	AltGr), the meta key (often Alt) and the num lock key, if applicable.
		926
		927	=item $view_start = $term->view_start ([$newvalue])
		928
		929	Returns the negative row number of the topmost line. Minimum value is
		930	C<0>, which displays the normal terminal contents. Larger values scroll
		931	this many lines into the scrollback buffer.
		932
		933	=item $term->want_refresh
		934
		935	Requests a screen refresh. At the next opportunity, rxvt-unicode will
		936	compare the on-screen display with its stored representation. If they
		937	differ, it redraws the differences.
		938
		939	Used after changing terminal contents to display them.
		940
		941	=item $text = $term->ROW_t ($row_number[, $new_text[, $start_col]])
		942
		943	Returns the text of the entire row with number C<$row_number>. Row C<0>
		944	is the topmost terminal line, row C<< $term->$ncol-1 >> is the bottommost
		945	terminal line. The scrollback buffer starts at line C<-1> and extends to
		946	line C<< -$term->nsaved >>. Nothing will be returned if a nonexistent line
		947	is requested.
		948
		949	If C<$new_text> is specified, it will replace characters in the current
		950	line, starting at column C<$start_col> (default C<0>), which is useful
		951	to replace only parts of a line. The font index in the rendition will
		952	automatically be updated.
		953
		954	C<$text> is in a special encoding: tabs and wide characters that use more
		955	than one cell when displayed are padded with urxvt::NOCHAR characters
		956	(C<chr 65535>). Characters with combining characters and other characters
		957	that do not fit into the normal tetx encoding will be replaced with
		958	characters in the private use area.
		959
		960	You have to obey this encoding when changing text. The advantage is
		961	that C<substr> and similar functions work on screen cells and not on
		962	characters.
		963
		964	The methods C<< $term->special_encode >> and C<< $term->special_decode >>
		965	can be used to convert normal strings into this encoding and vice versa.
		966
		967	=item $rend = $term->ROW_r ($row_number[, $new_rend[, $start_col]])
		968
		969	Like C<< $term->ROW_t >>, but returns an arrayref with rendition
		970	bitsets. Rendition bitsets contain information about colour, font, font
		971	styles and similar information. See also C<< $term->ROW_t >>.
		972
		973	When setting rendition, the font mask will be ignored.
		974
		975	See the section on RENDITION, above.
		976
		977	=item $length = $term->ROW_l ($row_number[, $new_length])
		978
		979	Returns the number of screen cells that are in use ("the line
		980	length"). Unlike the urxvt core, this returns C<< $term->ncol >> if the
		981	line is joined with the following one.
		982
		983	=item $bool = $term->is_longer ($row_number)
		984
		985	Returns true if the row is part of a multiple-row logical "line" (i.e.
		986	joined with the following row), which means all characters are in use
		987	and it is continued on the next row (and possibly a continuation of the
		988	previous row(s)).
		989
		990	=item $line = $term->line ($row_number)
		991
		992	Create and return a new C<urxvt::line> object that stores information
		993	about the logical line that row C<$row_number> is part of. It supports the
		994	following methods:
		995
		996	=over 4
		997
		998	=item $text = $line->t ([$new_text])
		999
		1000	Returns or replaces the full text of the line, similar to C<ROW_t>
		1001
		1002	=item $rend = $line->r ([$new_rend])
		1003
		1004	Returns or replaces the full rendition array of the line, similar to C<ROW_r>
		1005
		1006	=item $length = $line->l
		1007
		1008	Returns the length of the line in cells, similar to C<ROW_l>.
		1009
		1010	=item $rownum = $line->beg
		1011
		1012	=item $rownum = $line->end
		1013
		1014	Return the row number of the first/last row of the line, respectively.
		1015
		1016	=item $offset = $line->offset_of ($row, $col)
		1017
		1018	Returns the character offset of the given row\|col pair within the logical
		1019	line.
		1020
		1021	=item ($row, $col) = $line->coord_of ($offset)
		1022
		1023	Translates a string offset into terminal coordinates again.
