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. These comments are scanned whenever a
121terminal is created and are typically used to autoload extensions when
122their resources or command line parameters are used.
123
124Currently, it recognises these comments below. Individual components are
125separated by colons (C<:>), and should not contain colons themselves -
126there is also currently no escaping mechanism provided for this.
127
128=over
129
130=item #:META:RESOURCE:name:type:desc
131
132The RESOURCE comment defines a resource used by the extension, where
133C<name> is the resource name, C<type> is the resource type, C<boolean>
134or C<string>, and C<desc> is the resource description.
135
136The extension will be autoloaded when this resource is specified or used
137as a command line parameter.
138
139Example: matcher provides the C<matcher.launcher> resource by having this
140comment:
141
142 #:META:RESOURCE:%.launcher:string:default launcher command
143
144Example: load this extension when the C<-tr> command line option or
145resource name is used.
146
147 #:META:RESOURCE:tr:boolean:set root pixmap as background
148
149=item #:META:OSC:number:desc
150
151The OSC comment specifies an OSC sequence, where C<number> is the
152numerical OSC code and C<desc> is a short description that is currently
153unused.
154
155This will cause the extension to be autoloaded when the OSC sequence is
156used for the first time.
157
158Note that autoloading carries some extra responsibilities with it:
159although the terminal cannot really protect itself against malicious
160sources of command sequences, therefore relying on the programs running
161I<inside> to sanitize data that they output, it is very common for
162programs to emit command sequences from untrusted sources.
163
164While this means that extensions should, as a defense-in-depth mechanism,
165always consider whether OSC sequences are safe, autoloading automatically
166exposes any autoloaded extension in all terminal windows, so extra care
167should be taken.
168
169Example: the background extension registers OSC C<20> like this:
170
171 #:META:OSC:20:change/query background image
172
173=item #:META:OSC_PERL:prefix:desc
174
175The same as the OSC comment, but for the Perl OSC sequence (C<777>). The
176C<prefix> should be unique among extensions, of course, which is most
177easily arranged by using the extension name, although this is not
178required.
179
180Example: the overlay-osc extension registers its Perl OSC like this:
181
182 #:META:OSC_PERL:overlay:man overlay-osc

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.

207
208Unlike C<on_init> or C<on_start>, this is called when the extension is
209attached to a terminal, regardless of whether the extension is loaded
210before or after the terminal is started. Extensions that need to do
211something before they work can do it in this callback, as opposed to e.g.
212C<on_init>, which might not be called.

294Called on every OSC sequence and can be used to suppress it or modify its
295behaviour. The default should be to return an empty list. A true value
296suppresses execution of the request completely. Make sure you don't get

1334
1335Creates a new terminal, very similar as if you had started it with system
1336C<$rxvtname, arg...>. C<$envhashref> must be a reference to a C<%ENV>-like
1337hash which defines the environment of the new terminal.
1338
1339Croaks (and probably outputs an error message) if the new instance
1340couldn't be created. Returns C<undef> if the new instance didn't
1341initialise perl, and the terminal object otherwise. The C<init> and

1366the user environment before exec'ing the command (e.g. C<PATH>) and should

1455=item $value = $term->x_resource ($pattern)
1456
1457Returns the X-Resource for the given pattern, excluding the program or
1458class name, i.e. C<< $term->x_resource ("boldFont") >> should return the
1459same value as used by this instance of rxvt-unicode. Returns C<undef> if no
1460resource with that pattern exists.
1461
1462Extensions that define extra resources also need to call this method
1463to access their values.
1464
1465If the method is called on an extension object (basically, from an
1466extension), then the special prefix C<%.> will be replaced by the name of
1467the extension and a dot, and the lone string C<%> will be replaced by the
1468extension name itself. This makes it possible to code extensions so you
1469can rename them and get a new set of resources without having to change
1470the actual code.
1471
1472This method should only be called during the C<on_start> hook, as there is
1473only one resource database per display, and later invocations might return
1474the wrong resources.
1475
1476=item $value = $term->x_resource_boolean ($pattern)
1477
1478Like C<x_resource>, above, but interprets the string value as a boolean
1479and returns C<1> for true values, C<0> for false values and C<undef> if
1480the resource or option isn't specified.
1481
1482You should always use this method to parse boolean resources.

1496
1497=item $success = $term->bind_action ($key, $action)
1498
1499Adds a key binding exactly as specified via a C<keysym> resource. See the
1500C<keysym> resource in the urxvt(1) manpage.
1501
1502To add default bindings for actions, an extension should call C<<
1503->bind_action >> in its C<init> hook for every such binding. Doing it
1504in the C<init> hook allows users to override or remove the binding
1505again.
1506
1507Example: the C<searchable-scrollback> by default binds itself
1508on C<Meta-s>, using C<< $self->bind_action >>, which calls C<<
1509$term->bind_action >>.
