66Argument names also often indicate the type of a parameter. Here are some
67hints on what they mean:
68
69=over 4
70
71=item $text
72
73Rxvt-unicode's special way of encoding text, where one "unicode" character
74always represents one screen cell. See L<ROW_t> for a discussion of this format.
75
76=item $string
77
78A perl text string, with an emphasis on I<text>. It can store all unicode
79characters and is to be distinguished with text encoded in a specific
80encoding (often locale-specific) and binary data.
81
82=item $octets
83
84Either binary data or - more common - a text string encoded in a
85locale-specific way.
86
87=item $keysym
88
89an integer that is a valid X11 keysym code. You can convert a string
90into a keysym and viceversa by using C<XStringToKeysym> and
91C<XKeysymToString>.
92
93=back
94
95=head2 Extension Objects
96
97Every perl extension is a perl class. A separate perl object is created
98for each terminal, and each terminal has its own set of extension objects,
99which are passed as the first parameter to hooks. So extensions can use
100their C<$self> object without having to think about clashes with other
101extensions or other terminals, with the exception of methods and members
102that begin with an underscore character C<_>: these are reserved for
103internal use.
104
105Although it isn't a C<urxvt::term> object, you can call all methods of the
106C<urxvt::term> class on this object.
107
108It has the following methods and data members:
109
110=over 4
111
112=item $urxvt_term = $self->{term}
113
114Returns the C<urxvt::term> object associated with this instance of the
115extension. This member I<must not> be changed in any way.
116
117=item $self->enable ($hook_name => $cb[, $hook_name => $cb..])
118
119Dynamically enable the given hooks (named without the C<on_> prefix) for
120this extension, replacing any previous hook. This is useful when you want
121to overwrite time-critical hooks only temporarily.
122
123To install additional callbacks for the same hook, you cna use the C<on>
124method of the C<urxvt::term> class.
125
126=item $self->disable ($hook_name[, $hook_name..])
127
128Dynamically disable the given hooks.
129
130=item $self->x_resource ($pattern)
131
132=item $self->x_resource_boolean ($pattern)
133
134These methods support an additional C<%> prefix when called on an
135extension object - see the description of these methods in the
136C<urxvt::term> class for details.

107Called after a new terminal object has been initialized, but before 158Called after a new terminal object has been initialized, but before
108windows are created or the command gets run. 159windows are created or the command gets run. Most methods are unsafe to
160call or deliver senseless data, as terminal size and other characteristics
161have not yet been determined. You can safely query and change resources
162and options, though. For many purposes the C<on_start> hook is a better
163place.
164
165=item on_start $term

149Called whenever the window gets the keyboard focus, before urxvt does
150focus in processing.
151
152=item on_focus_out $term

172 233
173=item on_tty_activity $term *NYI* 234=item on_osc_seq $term, $op, $args, $resp
174 235
175Called whenever the program(s) running in the urxvt window send output. 236Called on every OSC sequence and can be used to suppress it or modify its
237behaviour. The default should be to return an empty list. A true value
238suppresses execution of the request completely. Make sure you don't get
239confused by recursive invocations when you output an OSC sequence within
240this callback.
241
242C<on_osc_seq_perl> should be used for new behaviour.
243
244=item on_osc_seq_perl $term, $args, $resp
245
246Called whenever the B<ESC ] 777 ; string ST> command sequence (OSC =
247operating system command) is processed. Cursor position and other state
248information is up-to-date when this happens. For interoperability, the
249string should start with the extension name (sans -osc) and a semicolon,
250to distinguish it from commands for other extensions, and this might be
251enforced in the future.
252
253For example, C<overlay-osc> uses this:
254
255 sub on_osc_seq_perl {
256 my ($self, $osc, $resp) = @_;
257
258 return unless $osc =~ s/^overlay;//;
259
260 ... process remaining $osc string
261 }
262
263Be careful not ever to trust (in a security sense) the data you receive,
264as its source can not easily be controlled (e-mail content, messages from
265other users on the same system etc.).
266
267For responses, C<$resp> contains the end-of-args separator used by the
268sender.
269
270=item on_add_lines $term, $string
271
272Called whenever text is about to be output, with the text as argument. You
273can filter/change and output the text yourself by returning a true value
274and calling C<< $term->scr_add_lines >> yourself. Please note that this
275might be very slow, however, as your hook is called for B<all> text being
276output.
277
278=item on_tt_write $term, $octets
279
280Called whenever some data is written to the tty/pty and can be used to
281suppress or filter tty input.
282
283=item on_tt_paste $term, $octets
284
285Called whenever text is about to be pasted, with the text as argument. You
286can filter/change and paste the text yourself by returning a true value
287and calling C<< $term->tt_paste >> yourself. C<$octets> is
288locale-encoded.
289
290=item on_line_update $term, $row
291
292Called whenever a line was updated or changed. Can be used to filter
293screen output (e.g. underline urls or other useless stuff). Only lines
294that are being shown will be filtered, and, due to performance reasons,
295not always immediately.
296
297The row number is always the topmost row of the line if the line spans
298multiple rows.
299
300Please note that, if you change the line, then the hook might get called
301later with the already-modified line (e.g. if unrelated parts change), so
302you cannot just toggle rendition bits, but only set them.
176 303
177=item on_refresh_begin $term 304=item on_refresh_begin $term
178 305
179Called just before the screen gets redrawn. Can be used for overlay 306Called just before the screen gets redrawn. Can be used for overlay or
180or similar effects by modify terminal contents in refresh_begin, and 307similar effects by modifying the terminal contents in refresh_begin, and
181restoring them in refresh_end. The built-in overlay and selection display 308restoring them in refresh_end. The built-in overlay and selection display
182code is run after this hook, and takes precedence. 309code is run after this hook, and takes precedence.

185 312
186Called just after the screen gets redrawn. See C<on_refresh_begin>. 313Called just after the screen gets redrawn. See C<on_refresh_begin>.
187 314

189 316
190Called whenever the user presses a key combination that has a 317Called whenever a user-configured event is being activated (e.g. via
191C<perl:string> action bound to it (see description of the B<keysym> 318a C<perl:string> action bound to a key, see description of the B<keysym>
192resource in the @@RXVT_NAME@@(1) manpage). 319resource in the @@RXVT_NAME@@(1) manpage).
193 320
321The event is simply the action string. This interface is assumed to change
322slightly in the future.
323
324=item on_register_command $term, $keysym, $modifiermask, $string
325
326Called after parsing a keysym resource but before registering the
327associated binding. If this hook returns TRUE the binding is not
328registered. It can be used to modify a binding by calling
329C<register_command>.
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 TRUE, 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.

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

885further programming. The only exception is that you cannot wait on
886condition variables, but non-blocking condvar use is ok.
887
888In practical terms this means is that you cannot use blocking APIs, but

1046
1047Creates a new terminal, very similar as if you had started it with system
1048C<$rxvtname, arg...>. C<$envhashref> must be a reference to a C<%ENV>-like
1049hash which defines the environment of the new terminal.
1050
1051Croaks (and probably outputs an error message) if the new instance
1052couldn't be created. Returns C<undef> if the new instance didn't
1053initialise perl, and the terminal object otherwise. The C<init> and
1054C<start> hooks will be called before this call returns, and are free to
1055refer to global data (which is race free).

1075
1076Similar to the extension method C<enable>, but installs additional
1077callbacks for the givne hook(s) (existing ones are not replaced), and
1078returns a guard object. When the guard object is destroyed the callbacks
1079are disabled again.

1204
1205Returns the X-Resource for the given pattern, excluding the program or
1206class name, i.e. C<< $term->x_resource ("boldFont") >> should return the
1207same value as used by this instance of rxvt-unicode. Returns C<undef> if no
1208resource with that pattern exists.
1209
1210Extensions that define extra resource or command line arguments also need
1211to call this method to access their values.
1212
1213If the method is called on an extension object (basically, from an
1214extension), then the special prefix C<%.> will be replaced by the name of
1215the extension and a dot, and the lone string C<%> will be replaced by the
1216extension name itself. This makes it possible to code extensions so you
1217can rename them and get a new set of commandline switches and resources
1218without having to change the actual code.
1219
1220This method should only be called during the C<on_start> hook, as there is
1221only one resource database per display, and later invocations might return
1222the wrong resources.
1223
1224=item $value = $term->x_resource_boolean ($pattern)
1225
1226Like C<x_resource>, above, but interprets the string value as a boolean
1227and returns C<1> for true values, C<0> for false values and C<undef> if
1228the resource or option isn't specified.

1244
1245=item $term->register_command ($keysym, $modifiermask, $string)
1246
1247Adds a key binding. This is a lower level api compared to
1248C<parse_keysym>, as it expects a parsed key description, and can be
1249used only inside either the C<on_init> hook, to add a binding, or the
1250C<on_register_command> hook, to modify a parsed binding.
