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.

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.

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

862Dynamically enable the given hooks (named without the C<on_> prefix) for
863this extension, replacing any hook previously installed via C<enable> in
864this extension.
865
866This is useful when you want to overwrite time-critical hooks only
867temporarily.
868
869To install additional callbacks for the same hook, you can use the C<on>
870method of the C<urxvt::term> class.

978The sole purpose of this class is to deliver an interface to the
979C<AnyEvent> module - any module using it will work inside urxvt without
980further programming. The only exception is that you cannot wait on
981condition variables, but non-blocking condvar use is ok.

983In practical terms this means is that you cannot use blocking APIs, but

1158Creates a new terminal, very similar as if you had started it with system
1159C<$rxvtname, arg...>. C<$envhashref> must be a reference to a C<%ENV>-like
1160hash which defines the environment of the new terminal.
1161
1162Croaks (and probably outputs an error message) if the new instance
1163couldn't be created. Returns C<undef> if the new instance didn't
1164initialise perl, and the terminal object otherwise. The C<init> and
1165C<start> hooks will be called before this call returns, and are free to
1166refer to global data (which is race free).

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

1295and returns C<1> for true values, C<0> for false values and C<undef> if
1296the resource or option isn't specified.
