		123

		125
		126	A perl text string, with an emphasis on I<text>. It can store all unicode
		127	characters and is to be distinguished with text encoded in a specific
		128	encoding (often locale-specific) and binary data.
		129

		137	=head2 Extension Objects
		138
		139	Very perl extension is a perl class. A separate perl object is created
		140	for each terminal and each extension and passed as the first parameter to
		141	hooks. So extensions can use their C<$self> object without having to think
		142	about other extensions, with the exception of methods and members that
		143	begin with an underscore character C<_>: these are reserved for internal
		144	use.
		145
		146	Although it isn't a C<urxvt::term> object, you can call all methods of the
		147	C<urxvt::term> class on this object.
		148
		149	It has the following methods and data members:
		150
		151	=over 4

		157
		158	=item $self->enable ($hook_name => $cb, [$hook_name => $cb..])
		159
		160	Dynamically enable the given hooks (named without the C<on_> prefix) for
		161	this extension, replacing any previous hook. This is useful when you want
		162	to overwrite time-critical hooks only temporarily.

167	Called whenever the program(s) running in the urxvt window send output.	249	Called whenever the B<ESC ] 777 ; string ST> command sequence (OSC =
		250	operating system command) is processed. Cursor position and other state
		251	information is up-to-date when this happens. For interoperability, the
		252	string should start with the extension name and a colon, to distinguish
		253	it from commands for other extensions, and this might be enforced in the
		254	future.
		255
		256	Be careful not ever to trust (in a security sense) the data you receive,
		257	as its source can not easily be controleld (e-mail content, messages from
		258	other users on the same system etc.).
		259
		260	=item on_add_lines $term, $string
		261
		262	Called whenever text is about to be output, with the text as argument. You
		263	can filter/change and output the text yourself by returning a true value
		264	and calling C<< $term->scr_add_lines >> yourself. Please note that this
		265	might be very slow, however, as your hook is called for B<all> text being
		266	output.
		267
		268	=item on_tt_write $term, $octets
		269
		270	Called whenever some data is written to the tty/pty and can be used to
		271	suppress or filter tty input.
		272
		273	=item on_line_update $term, $row
		274
		275	Called whenever a line was updated or changed. Can be used to filter
		276	screen output (e.g. underline urls or other useless stuff). Only lines
		277	that are being shown will be filtered, and, due to performance reasons,
		278	not always immediately.
		279
		280	The row number is always the topmost row of the line if the line spans
		281	multiple rows.
		282
		283	Please note that, if you change the line, then the hook might get called
		284	later with the already-modified line (e.g. if unrelated parts change), so
		285	you cannot just toggle rendition bits, but only set them.
