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

859
860Dynamically enable the given hooks (named without the C<on_> prefix) for
861this extension, replacing any hook previously installed via C<enable> in
862this extension.
863
864This is useful when you want to overwrite time-critical hooks only
865temporarily.
866
867To install additional callbacks for the same hook, you can use the C<on>
868method of the C<urxvt::term> class.

1156Creates a new terminal, very similar as if you had started it with system
1157C<$rxvtname, arg...>. C<$envhashref> must be a reference to a C<%ENV>-like
1158hash which defines the environment of the new terminal.
1159
1160Croaks (and probably outputs an error message) if the new instance
1161couldn't be created. Returns C<undef> if the new instance didn't
1162initialise perl, and the terminal object otherwise. The C<init> and
1163C<start> hooks will be called before this call returns, and are free to

1270
1271Returns the X-Resource for the given pattern, excluding the program or
1272class name, i.e. C<< $term->x_resource ("boldFont") >> should return the
1273same value as used by this instance of rxvt-unicode. Returns C<undef> if no
1274resource with that pattern exists.
1275
1276Extensions that define extra resource or command line arguments also need
1277to call this method to access their values.
1278
1279If the method is called on an extension object (basically, from an
1280extension), then the special prefix C<%.> will be replaced by the name of
1281the extension and a dot, and the lone string C<%> will be replaced by the
1282extension name itself. This makes it possible to code extensions so you
1283can rename them and get a new set of commandline switches and resources
1284without having to change the actual code.
1285
1286This method should only be called during the C<on_start> hook, as there is
1287only one resource database per display, and later invocations might return
1288the wrong resources.
