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.

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

853 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.
