143=head2 Extension Objects
144
145Very perl extension is a perl class. A separate perl object is created
146for each terminal and each extension and passed as the first parameter to
147hooks. So extensions can use their C<$self> object without having to think
148about other extensions, with the exception of methods and members that
149begin with an underscore character C<_>: these are reserved for internal
150use.
151
152Although it isn't a C<urxvt::term> object, you can call all methods of the
153C<urxvt::term> class on this object.
154
155It has the following methods and data members:
156

158
159=item $urxvt_term = $self->{term}

161Returns the C<urxvt::term> object associated with this instance of the
162extension. This member I<must not> be changed in any way.
163
164=item $self->enable ($hook_name => $cb, [$hook_name => $cb..])
165
166Dynamically enable the given hooks (named without the C<on_> prefix) for
167this extension, replacing any previous hook. This is useful when you want
168to overwrite time-critical hooks only temporarily.
169
170=item $self->disable ($hook_name[, $hook_name..])

132object that is shared between all packages is stored in the C<term>
133member. It is, however, blessed intot he package of the extension script,
134so for all practical purposes you can treat an extension script as a class.

693C<AnyEvent> module - any module using it will work inside urxvt without
694further programming. The only exception is that you cannot wait on

696is that you cannot use blocking APIs, but the non-blocking variant should
