		99	Argument names also often indicate the type of a parameter. Here are
		100	some hints on what they mean:
		101
		102	$text
		103	Rxvt-unicodes special way of encoding text, where one "unicode"
		104	character always represents one screen cell. See ROW_t for a
		105	discussion of this format.
		106
		107	$string
		108	A perl text string, with an emphasis on text. It can store all
		109	unicode characters and is to be distinguished with text encoded in a
		110	specific encoding (often locale-specific) and binary data.
		111
		112	$octets
		113	Either binary data or - more common - a text string encoded in a
		114	locale-specific way.
		115
		116	Extension Objects
		117	Very perl extension is a perl class. A separate perl object is created
		118	for each terminal and each extension and passed as the first parameter
		119	to hooks. So extensions can use their $self object without having to
		120	think about other extensions, with the exception of methods and members
		121	that begin with an underscore character "_": these are reserved for
		122	internal use.
		123
		124	Although it isn't a "urxvt::term" object, you can call all methods of
		125	the "urxvt::term" class on this object.
		126
		127	It has the following methods and data members:
		128
		129	$urxvt_term = $self->{term}
		130	Returns the "urxvt::term" object associated with this instance of
		131	the extension. This member must not be changed in any way.
		132
		133	$self->enable ($hook_name => $cb, [$hook_name => $cb..])
		134	Dynamically enable the given hooks (named without the "on_" prefix)
		135	for this extension, replacing any previous hook. This is useful when
		136	you want to overwrite time-critical hooks only temporarily.
		137
		138	$self->disable ($hook_name[, $hook_name..])
		139	Dynamically disable the given hooks.

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

		553
