101
102=head2 Extension Objects
103
104Every perl extension is a perl class. A separate perl object is created
105for each terminal, and each terminal has its own set of extension objects,
106which are passed as the first parameter to hooks. So extensions can use
107their C<$self> object without having to think about clashes with other
108extensions or other terminals, with the exception of methods and members
109that begin with an underscore character C<_>: these are reserved for
110internal use.
111
112Although it isn't a C<urxvt::term> object, you can call all methods of the
113C<urxvt::term> class on this object.
114
115Additional methods only supported for extension objects are described in
116the C<urxvt::extension> section below.
117
118=head2 META comments
119
120Rxvt-unicode recognizes special meta comments in extensions that define
121different types of metadata.
122
123Currently, it recxognises only one such comment:
124
125=over 4
126
127=item #:META:RESOURCE:name:type:desc
128
129The RESOURCE comment defines a resource used by the extension, where
130C<name> is the resource name, C<type> is the resource type, C<boolean>
131or C<string>, and C<desc> is the resource description.

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.

447gets cleared before the code references that were in it are being executed,

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.
894
895=item $self->disable ($hook_name[, $hook_name..])
896
897Dynamically disable the given hooks.

932
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.

1199Creates a new terminal, very similar as if you had started it with system
1200C<$rxvtname, arg...>. C<$envhashref> must be a reference to a C<%ENV>-like
1201hash which defines the environment of the new terminal.
1202
1203Croaks (and probably outputs an error message) if the new instance
1204couldn't be created. Returns C<undef> if the new instance didn't
1205initialise perl, and the terminal object otherwise. The C<init> and
1206C<start> hooks will be called before this call returns, and are free to

1312=item $value = $term->x_resource ($pattern)
1313
1314Returns the X-Resource for the given pattern, excluding the program or
1315class name, i.e. C<< $term->x_resource ("boldFont") >> should return the
1316same value as used by this instance of rxvt-unicode. Returns C<undef> if no
1317resource with that pattern exists.
1318
1319Extensions that define extra resources also need to call this method
1320to access their values.
1321
1322If the method is called on an extension object (basically, from an
1323extension), then the special prefix C<%.> will be replaced by the name of
1324the extension and a dot, and the lone string C<%> will be replaced by the
1325extension name itself. This makes it possible to code extensions so you
1326can rename them and get a new set of resources without having to change
1327the actual code.
1328
1329This method should only be called during the C<on_start> hook, as there is
1330only one resource database per display, and later invocations might return
1331the wrong resources.
1332
1333=item $value = $term->x_resource_boolean ($pattern)
1334
1335Like C<x_resource>, above, but interprets the string value as a boolean
1336and returns C<1> for true values, C<0> for false values and C<undef> if
1337the resource or option isn't specified.
1338
1339You should always use this method to parse boolean resources.

1349=item $success = $term->bind_action ($key, $action)
1350
1351Adds a key binding exactly as specified via a C<keysym> resource. See the
1352C<keysym> resource in the urxvt(1) manpage.
1353
1354To add default bindings for an extension, the extension should call C<<
1355->bind_action >> on it's C<init> hook for every such binding. Doing it
1356in the C<init> hook allows users the override or remove the the binding
1357again.
1358
1359Example: the C<searchable-scrollback> by default binds itself
1360on C<Meta-s>, using C<< $self->bind_action >>, which calls C<<
1361$term->bind_action >>.
