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 only one such comment:
125
126=over 4
127
128=item #:META:RESOURCE:name:type:desc
129
130The RESOURCE comment defines a resource used by the extension, where
131C<name> is the resource name, C<type> is the resource type, C<boolean>
132or C<string>, and C<desc> is the resource description.
133
134The extension will be autoloaded when this resource is specified or used
135as a command line parameter.

138windows are created or the command gets run. 158windows are created or the command gets run. Most methods are unsafe to
159call or deliver senseless data, as terminal size and other characteristics
160have not yet been determined. You can safely query and change resources
161and options, though. For many purposes the C<on_start> hook is a better
162place.

235Called on every OSC sequence and can be used to suppress it or modify its
236behaviour. The default should be to return an empty list. A true value
237suppresses execution of the request completely. Make sure you don't get
238confused by recursive invocations when you output an OSC sequence within
239this callback.

288
289=item on_line_update $term, $row
290
291Called whenever a line was updated or changed. Can be used to filter
292screen output (e.g. underline urls or other useless stuff). Only lines
293that are being shown will be filtered, and, due to performance reasons,
294not always immediately.
295
296The row number is always the topmost row of the line if the line spans
297multiple rows.
298
299Please note that, if you change the line, then the hook might get called
300later with the already-modified line (e.g. if unrelated parts change), so
301you cannot just toggle rendition bits, but only set them.

314=item on_action $term, $string
315
316Called whenever an action is invoked for the corresponding extension
317(e.g. via a C<extension:string> builtin action bound to a key, see
318description of the B<keysym> resource in the urxvt(1) manpage). The
319event is simply the action string. Note that an action event is always
320associated to a single extension.
321

243resource in the @@RXVT_NAME@@(1) manpage). 326resource in the urxvt(1) manpage).
327
328The event is simply the action string. This interface is going away in
329preference to the C<on_action> hook.
330
331=item on_resize_all_windows $term, $new_width, $new_height
332
333Called just after the new window size has been calculated, but before
334windows are actually being resized or hints are being set. If this hook
335returns a true value, setting of the window hints is being skipped.
336
337=item on_x_event $term, $event
338
339Called on every X event received on the vt window (and possibly other
340windows). Should only be used as a last resort. Most event structure
341members are not passed.
342
343=item on_root_event $term, $event
344
345Like C<on_x_event>, but is called for events on the root window.
346
347=item on_focus_in $term
348
349Called whenever the window gets the keyboard focus, before rxvt-unicode
350does focus in processing.
351
352=item on_focus_out $term
353
354Called whenever the window loses keyboard focus, before rxvt-unicode does
355focus out processing.

372
373=item on_unmap_notify $term, $event
374
375Called whenever the corresponding X event is received for the terminal. If
376the hook returns true, then the event will be ignored by rxvt-unicode.
377
378The event is a hash with most values as named by Xlib (see the XEvent
379manpage), with the additional members C<row> and C<col>, which are the
380(real, not screen-based) row and column under the mouse cursor.
381
382C<on_key_press> additionally receives the string rxvt-unicode would

905Dynamically enable the given hooks (named without the C<on_> prefix) for

907this extension.
908
909This is useful when you want to overwrite time-critical hooks only
910temporarily.
911
912To install additional callbacks for the same hook, you can use the C<on>
913method of the C<urxvt::term> class.

1030The sole purpose of this class is to deliver an interface to the
1031C<AnyEvent> module - any module using it will work inside urxvt without
1032further programming. The only exception is that you cannot wait on
1033condition variables, but non-blocking condvar use is ok.
1034
1035In practical terms this means is that you cannot use blocking APIs, but
1036the non-blocking variant should work.

1220=item $term = new urxvt::term $envhashref, $rxvtname, [arg...]
1221
1222Creates a new terminal, very similar as if you had started it with system
1223C<$rxvtname, arg...>. C<$envhashref> must be a reference to a C<%ENV>-like
1224hash which defines the environment of the new terminal.
1225
1226Croaks (and probably outputs an error message) if the new instance
1227couldn't be created. Returns C<undef> if the new instance didn't
1228initialise perl, and the terminal object otherwise. The C<init> and
1229C<start> hooks will be called before this call returns, and are free to
1230refer to global data (which is race free).

1253the user environment before exec'ing the command (e.g. C<PATH>) and should
1254be preferred over explicit calls to C<exec> or C<system>.

1336
1337Returns the X-Resource for the given pattern, excluding the program or
1338class name, i.e. C<< $term->x_resource ("boldFont") >> should return the
1339same value as used by this instance of rxvt-unicode. Returns C<undef> if no
1340resource with that pattern exists.
1341
1342Extensions that define extra resources also need to call this method
1343to access their values.
1344
1345If the method is called on an extension object (basically, from an
1346extension), then the special prefix C<%.> will be replaced by the name of
1347the extension and a dot, and the lone string C<%> will be replaced by the
1348extension name itself. This makes it possible to code extensions so you
1349can rename them and get a new set of resources without having to change
1350the actual code.
1351
1352This method should only be called during the C<on_start> hook, as there is
1353only one resource database per display, and later invocations might return
1354the wrong resources.
1355
1356=item $value = $term->x_resource_boolean ($pattern)
1357
1358Like C<x_resource>, above, but interprets the string value as a boolean
1359and returns C<1> for true values, C<0> for false values and C<undef> if
1360the resource or option isn't specified.
1361
1362You should always use this method to parse boolean resources.

1372=item $action = $term->lookup_keysym ($keysym, $state)
1373
1374Returns the action bound to key combination C<($keysym, $state)>,
1375if a binding for it exists, and C<undef> otherwise.
1376
1377=item $success = $term->bind_action ($key, $action)
1378
1379Adds a key binding exactly as specified via a C<keysym> resource. See the
1380C<keysym> resource in the urxvt(1) manpage.
1381
1382To add default bindings for actions, an extension should call C<<
1383->bind_action >> in its C<init> hook for every such binding. Doing it
1384in the C<init> hook allows users to override or remove the binding
1385again.
1386
1387Example: the C<searchable-scrollback> by default binds itself
1388on C<Meta-s>, using C<< $self->bind_action >>, which calls C<<
1389$term->bind_action >>.
