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.

131its not a real C<urxvt::term> object. Instead, the real C<urxvt::term>
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.

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

860
861Dynamically enable the given hooks (named without the C<on_> prefix) for
862this extension, replacing any hook previously installed via C<enable> in
863this extension.
864
865This is useful when you want to overwrite time-critical hooks only
866temporarily.
867
868To install additional callbacks for the same hook, you can use the C<on>
869method of the C<urxvt::term> class.

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

1271
1272Returns the X-Resource for the given pattern, excluding the program or
1273class name, i.e. C<< $term->x_resource ("boldFont") >> should return the
1274same value as used by this instance of rxvt-unicode. Returns C<undef> if no
1275resource with that pattern exists.
1276
1277Extensions that define extra resource or command line arguments also need
1278to call this method to access their values.
1279
1280If the method is called on an extension object (basically, from an
1281extension), then the special prefix C<%.> will be replaced by the name of
1282the extension and a dot, and the lone string C<%> will be replaced by the
1283extension name itself. This makes it possible to code extensions so you
1284can rename them and get a new set of commandline switches and resources
1285without having to change the actual code.
1286
1287This method should only be called during the C<on_start> hook, as there is
1288only one resource database per display, and later invocations might return
1289the wrong resources.
1290
1291=item $value = $term->x_resource_boolean ($pattern)

1294and returns C<1> for true values, C<0> for false values and C<undef> if
1295the resource or option isn't specified.
1296
1297You should always use this method to parse boolean resources.
