831=head2 The C<urxvt::term::extension> class
832
833Each extension attached to a terminal object is represented by
834a C<urxvt::term::extension> object.
835
836You can use these objects, which are passed to all callbacks to store any
837state related to the terminal and extension instance.
838
839The methods (And data members) documented below can be called on extension
840objects, in addition to call methods documented for the <urxvt::term>
841class.

884
885Dynamically enable the given hooks (named without the C<on_> prefix) for
886this extension, replacing any hook previously installed via C<enable> in
887this extension.
888
889This is useful when you want to overwrite time-critical hooks only
890temporarily.
891
892To install additional callbacks for the same hook, you can use the C<on>
893method of the C<urxvt::term> class.

933Similar to the C<enable> enable, but installs additional callbacks for
934the given hook(s) (that is, it doesn't replace existing callbacks), and
935returns a guard object. When the guard object is destroyed the callbacks
936are disabled again.

1186Creates a new terminal, very similar as if you had started it with system
1187C<$rxvtname, arg...>. C<$envhashref> must be a reference to a C<%ENV>-like
1188hash which defines the environment of the new terminal.
1189
1190Croaks (and probably outputs an error message) if the new instance
1191couldn't be created. Returns C<undef> if the new instance didn't
1192initialise perl, and the terminal object otherwise. The C<init> and

832 1300
1301Returns the X-Resource for the given pattern, excluding the program or
1302class name, i.e. C<< $term->x_resource ("boldFont") >> should return the
1303same value as used by this instance of rxvt-unicode. Returns C<undef> if no
1304resource with that pattern exists.
1305
1306Extensions that define extra resources also need to call this method
1307to access their values.
1308
1309If the method is called on an extension object (basically, from an
1310extension), then the special prefix C<%.> will be replaced by the name of
1311the extension and a dot, and the lone string C<%> will be replaced by the
1312extension name itself. This makes it possible to code extensions so you
1313can rename them and get a new set of resources without having to change
1314the actual code.
1315
1316This method should only be called during the C<on_start> hook, as there is
1317only one resource database per display, and later invocations might return
1318the wrong resources.
1319
1320=item $value = $term->x_resource_boolean ($pattern)
1321
1322Like C<x_resource>, above, but interprets the string value as a boolean
1323and returns C<1> for true values, C<0> for false values and C<undef> if
1324the resource or option isn't specified.
1325
1326You should always use this method to parse boolean resources.

1340
1341To add default bindings for an extension, the extension should call C<<
1342->bind_action >> on it's C<init> hook for every such binding. Doing it
1343in the C<init> hook allows users the override or remove the the binding
1344again.
1345
1346Example: the C<searchable-scrollback> by default binds itself
1347on C<Meta-s>, using C<< $self->bind_action >>, which calls C<<
