847
848Each extension attached to a terminal object is represented by
849a C<urxvt::term::extension> object.
850
851You can use these objects, which are passed to all callbacks to store any
852state related to the terminal and extension instance.
853
854The methods (And data members) documented below can be called on extension
855objects, in addition to call methods documented for the <urxvt::term>
856class.

899
900Dynamically enable the given hooks (named without the C<on_> prefix) for
901this extension, replacing any hook previously installed via C<enable> in
902this extension.
903
904This is useful when you want to overwrite time-critical hooks only
905temporarily.
906
907To install additional callbacks for the same hook, you can use the C<on>
908method of the C<urxvt::term> class.

948Similar to the C<enable> enable, but installs additional callbacks for
949the given hook(s) (that is, it doesn't replace existing callbacks), and
950returns a guard object. When the guard object is destroyed the callbacks

1198hash which defines the environment of the new terminal.
1199
1200Croaks (and probably outputs an error message) if the new instance
1201couldn't be created. Returns C<undef> if the new instance didn't
1202initialise perl, and the terminal object otherwise. The C<init> and

1311Returns the X-Resource for the given pattern, excluding the program or
1312class name, i.e. C<< $term->x_resource ("boldFont") >> should return the
1313same value as used by this instance of rxvt-unicode. Returns C<undef> if no
1314resource with that pattern exists.
1315
1316Extensions that define extra resources also need to call this method
1317to access their values.
1318
1319If the method is called on an extension object (basically, from an
1320extension), then the special prefix C<%.> will be replaced by the name of
1321the extension and a dot, and the lone string C<%> will be replaced by the
1322extension name itself. This makes it possible to code extensions so you
1323can rename them and get a new set of resources without having to change
1324the actual code.
1325
1326This method should only be called during the C<on_start> hook, as there is
1327only one resource database per display, and later invocations might return
1328the wrong resources.
