137=head2 Extension Objects
138
139Very perl extension is a perl class. A separate perl object is created
140for each terminal and each extension and passed as the first parameter to
141hooks. So extensions can use their C<$self> object without having to think
142about other extensions, with the exception of methods and members that
143begin with an underscore character C<_>: these are reserved for internal
144use.
145
146Although it isn't a C<urxvt::term> object, you can call all methods of the
147C<urxvt::term> class on this object.
148
149It has the following methods and data members:
150
151=over 4
152
153=item $urxvt_term = $self->{term}
154
155Returns the C<urxvt::term> object associated with this instance of the
156extension. This member I<must not> be changed in any way.
157
158=item $self->enable ($hook_name => $cb, [$hook_name => $cb..])
159
160Dynamically enable the given hooks (named without the C<on_> prefix) for
161this extension, replacing any previous hook. This is useful when you want
162to overwrite time-critical hooks only temporarily.
163
164=item $self->disable ($hook_name[, $hook_name..])

166Dynamically disable the given hooks.

127object that is shared between all packages is stored in the C<term>
128member. It is, however, blessed intot he package of the extension script,
129so for all practical purposes you can treat an extension script as a class.
