		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.
		163

		977	string is a normal text string, not in locale-dependent encoding.
		978
		979	Normally its not a good idea to use this function, as programs might be
		980	confused by changes in cursor position or scrolling. Its useful inside a
		981	C<on_add_lines> hook, though.
		982
		983	=item $term->cmd_parse ($octets)
		984
		985	Similar to C<scr_add_lines>, but the argument must be in the
		986	locale-specific encoding of the terminal and can contain command sequences
		987	(escape codes) that will be interpreted.
