95=head2 Extension Objects
96
97Every perl extension is a perl class. A separate perl object is created
98for each terminal, and each terminal has its own set of extension objects,
99which are passed as the first parameter to hooks. So extensions can use
100their C<$self> object without having to think about clashes with other
101extensions or other terminals, with the exception of methods and members
102that begin with an underscore character C<_>: these are reserved for
103internal use.
104
105Although it isn't a C<urxvt::term> object, you can call all methods of the
106C<urxvt::term> class on this object.
107
108Additional methods only supported for extension objects are described in
109the C<urxvt::extension> section below.

136its not a real C<urxvt::term> object. Instead, the real C<urxvt::term>
137object that is shared between all packages is stored in the C<term>
138member. It is, however, blessed intot he package of the extension script,
139so for all practical purposes you can treat an extension script as a class.

141All of them must return a boolean value. If it is true, then the event 119B<All> of these hooks must return a boolean value. If any of the called

415gets cleared before the code references that were in it are being executed,

827
828Dynamically enable the given hooks (named without the C<on_> prefix) for
829this extension, replacing any hook previously installed via C<enable> in
830this extension.
831
832This is useful when you want to overwrite time-critical hooks only
833temporarily.
834
835To install additional callbacks for the same hook, you can use the C<on>
836method of the C<urxvt::term> class.

1111Croaks (and probably outputs an error message) if the new instance

1221
1222Returns the X-Resource for the given pattern, excluding the program or

1224same value as used by this instance of rxvt-unicode. Returns C<undef> if no
1225resource with that pattern exists.
1226
1227Extensions that define extra resource or command line arguments also need
1228to call this method to access their values.
1229
1230If the method is called on an extension object (basically, from an
1231extension), then the special prefix C<%.> will be replaced by the name of
1232the extension and a dot, and the lone string C<%> will be replaced by the
1233extension name itself. This makes it possible to code extensions so you
1234can rename them and get a new set of commandline switches and resources
1235without having to change the actual code.
1236
1237This method should only be called during the C<on_start> hook, as there is
1238only one resource database per display, and later invocations might return
