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

886Dynamically enable the given hooks (named without the C<on_> prefix) for

888this extension.
889
890This is useful when you want to overwrite time-critical hooks only
891temporarily.

893To install additional callbacks for the same hook, you can use the C<on>
894method of the C<urxvt::term> class.

1011The sole purpose of this class is to deliver an interface to the
1012C<AnyEvent> module - any module using it will work inside urxvt without
1013further programming. The only exception is that you cannot wait on
1014condition variables, but non-blocking condvar use is ok.
1015
1016In practical terms this means is that you cannot use blocking APIs, but
1017the non-blocking variant should work.

1202
1203Creates a new terminal, very similar as if you had started it with system
1204C<$rxvtname, arg...>. C<$envhashref> must be a reference to a C<%ENV>-like
1205hash which defines the environment of the new terminal.
1206
1207Croaks (and probably outputs an error message) if the new instance
1208couldn't be created. Returns C<undef> if the new instance didn't
1209initialise perl, and the terminal object otherwise. The C<init> and
1210C<start> hooks will be called before this call returns, and are free to
1211refer to global data (which is race free).

1317
1318Returns the X-Resource for the given pattern, excluding the program or
1319class name, i.e. C<< $term->x_resource ("boldFont") >> should return the
1320same value as used by this instance of rxvt-unicode. Returns C<undef> if no
1321resource with that pattern exists.
1322
1323Extensions that define extra resources also need to call this method
1324to access their values.
1325
1326If the method is called on an extension object (basically, from an
1327extension), then the special prefix C<%.> will be replaced by the name of
1328the extension and a dot, and the lone string C<%> will be replaced by the
1329extension name itself. This makes it possible to code extensions so you
1330can rename them and get a new set of resources without having to change
1331the actual code.
1332
1333This method should only be called during the C<on_start> hook, as there is
1334only one resource database per display, and later invocations might return
1335the wrong resources.
1336
1337=item $value = $term->x_resource_boolean ($pattern)
1338
1339Like C<x_resource>, above, but interprets the string value as a boolean
1340and returns C<1> for true values, C<0> for false values and C<undef> if
1341the resource or option isn't specified.
1342
1343You should always use this method to parse boolean resources.

1356if a binding for it exists, and C<undef> otherwise.
1357
1358=item $success = $term->bind_action ($key, $action)
1359
1360Adds a key binding exactly as specified via a C<keysym> resource. See the
1361C<keysym> resource in the urxvt(1) manpage.
1362
1363To add default bindings for actions, an extension should call C<<
1364->bind_action >> in its C<init> hook for every such binding. Doing it
1365in the C<init> hook allows users to override or remove the binding
1366again.
1367
1368Example: the C<searchable-scrollback> by default binds itself
1369on C<Meta-s>, using C<< $self->bind_action >>, which calls C<<
1370$term->bind_action >>.
