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
123=item $self->disable ($hook_name[, $hook_name..])
124
125Dynamically disable the given hooks.

94object that is shared between all packages is stored in the C<term>
95member.

108windows are created or the command gets run. 148windows are created or the command gets run. Most methods are unsafe to
149call or deliver senseless data, as terminal size and other characteristics
150have not yet been determined. You can safely query and change resources
151and options, though. For many purposes the C<on_start> hook is a better
152place.

176
177=item on_osc_seq $term, $string 223=item on_osc_seq $term, $op, $args, $resp
224
225Called on every OSC sequence and can be used to suppress it or modify its
226behaviour. The default should be to return an empty list. A true value
227suppresses execution of the request completely. Make sure you don't get
228confused by recursive invocations when you output an OSC sequence within
229this callback.
230
231C<on_osc_seq_perl> should be used for new behaviour.

180operating system command) is processed. Cursor position and other state 236operating system command) is processed. Cursor position and other state
181information is up-to-date when this happens. For interoperability, the 237information is up-to-date when this happens. For interoperability, the

184future. 240enforced in the future.
241
242For example, C<overlay-osc> uses this:

188other users on the same system etc.). 254other users on the same system etc.).
189 255
256For responses, C<$resp> contains the end-of-args separator used by the
257sender.
258
259=item on_add_lines $term, $string
260
261Called whenever text is about to be output, with the text as argument. You
262can filter/change and output the text yourself by returning a true value
263and calling C<< $term->scr_add_lines >> yourself. Please note that this
264might be very slow, however, as your hook is called for B<all> text being
265output.
266
267=item on_tt_write $term, $octets
268
269Called whenever some data is written to the tty/pty and can be used to
270suppress or filter tty input.
271
272=item on_tt_paste $term, $octets
273
274Called whenever text is about to be pasted, with the text as argument. You
275can filter/change and paste the text yourself by returning a true value
276and calling C<< $term->tt_paste >> yourself. C<$octets> is
277locale-encoded.
278
279=item on_line_update $term, $row
280
281Called whenever a line was updated or changed. Can be used to filter
282screen output (e.g. underline urls or other useless stuff). Only lines
283that are being shown will be filtered, and, due to performance reasons,
284not always immediately.
285
286The row number is always the topmost row of the line if the line spans
287multiple rows.
288
289Please note that, if you change the line, then the hook might get called
290later with the already-modified line (e.g. if unrelated parts change), so
291you cannot just toggle rendition bits, but only set them.
292
190=item on_refresh_begin $term 293=item on_refresh_begin $term
191 294
192Called just before the screen gets redrawn. Can be used for overlay 295Called just before the screen gets redrawn. Can be used for overlay or
193or similar effects by modify terminal contents in refresh_begin, and 296similar effects by modifying the terminal contents in refresh_begin, and
194restoring them in refresh_end. The built-in overlay and selection display 297restoring them in refresh_end. The built-in overlay and selection display

310The event is simply the action string. This interface is assumed to change
311slightly in the future.
312
313=item on_register_command $term, $keysym, $modifiermask, $string
314
315Called after parsing a keysym resource but before registering the
316associated binding. If this hook returns TRUE the binding is not
317registered. It can be used to modify a binding by calling
318C<register_command>.
319
320=item on_resize_all_windows $term, $new_width, $new_height
321
322Called just after the new window size has been calculated, but before
323windows are actually being resized or hints are being set. If this hook
324returns TRUE, setting of the window hints is being skipped.
325
326=item on_x_event $term, $event
327
328Called on every X event received on the vt window (and possibly other
329windows). Should only be used as a last resort. Most event structure
330members are not passed.
331
332=item on_root_event $term, $event
333
334Like C<on_x_event>, but is called for events on the root window.
335
336=item on_focus_in $term
337
338Called whenever the window gets the keyboard focus, before rxvt-unicode
339does focus in processing.
340
341=item on_focus_out $term
342
343Called whenever the window loses keyboard focus, before rxvt-unicode does
344focus out processing.

361
362=item on_unmap_notify $term, $event
363
364Called whenever the corresponding X event is received for the terminal. If
365the hook returns true, then the event will be ignored by rxvt-unicode.
366
367The event is a hash with most values as named by Xlib (see the XEvent
368manpage), with the additional members C<row> and C<col>, which are the
369(real, not screen-based) row and column under the mouse cursor.
370
371C<on_key_press> additionally receives the string rxvt-unicode would

874further programming. The only exception is that you cannot wait on
875condition variables, but non-blocking condvar use is ok.

877In practical terms this means is that you cannot use blocking APIs, but

1035
1036Creates a new terminal, very similar as if you had started it with system
1037C<$rxvtname, arg...>. C<$envhashref> must be a reference to a C<%ENV>-like
1038hash which defines the environment of the new terminal.
1039
1040Croaks (and probably outputs an error message) if the new instance
1041couldn't be created. Returns C<undef> if the new instance didn't
1042initialise perl, and the terminal object otherwise. The C<init> and
1043C<start> hooks will be called before this call returns, and are free to
1044refer to global data (which is race free).

1150
1151Returns the X-Resource for the given pattern, excluding the program or
1152class name, i.e. C<< $term->x_resource ("boldFont") >> should return the
1153same value as used by this instance of rxvt-unicode. Returns C<undef> if no
1154resource with that pattern exists.
1155
1156Extensions that define extra resource or command line arguments also need
1157to call this method to access their values.
1158
1159If the method is called on an extension object (basically, from an
1160extension), then the special prefix C<%.> will be replaced by the name of
1161the extension and a dot, and the lone string C<%> will be replaced by the
1162extension name itself. This makes it possible to code extensions so you
1163can rename them and get a new set of commandline switches and resources
1164without having to change the actual code.
1165
1166This method should only be called during the C<on_start> hook, as there is
1167only one resource database per display, and later invocations might return
1168the wrong resources.
1169
1170=item $value = $term->x_resource_boolean ($pattern)
1171
1172Like C<x_resource>, above, but interprets the string value as a boolean
1173and returns C<1> for true values, C<0> for false values and C<undef> if
1174the resource or option isn't specified.

1192
1193Adds a key binding. This is a lower level api compared to
1194C<parse_keysym>, as it expects a parsed key description, and can be
1195used only inside either the C<on_init> hook, to add a binding, or the
