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.

126its not a real C<urxvt::term> object. Instead, the real C<urxvt::term>
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.

424gets cleared before the code references that were in it are being executed,

944The sole purpose of this class is to deliver an interface to the

947condition variables, but non-blocking condvar use is ok.

949In practical terms this means is that you cannot use blocking APIs, but

1109hash which defines the environment of the new terminal.
1110
1111Croaks (and probably outputs an error message) if the new instance
1112couldn't be created. Returns C<undef> if the new instance didn't
1113initialise perl, and the terminal object otherwise. The C<init> and

1222Returns the X-Resource for the given pattern, excluding the program or
1223class name, i.e. C<< $term->x_resource ("boldFont") >> should return the
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
1239the wrong resources.
