122Argument names also often indicate the type of a parameter. Here are some
123hints on what they mean:

125=over 4
126
127=item $text
128
129Rxvt-unicodes special way of encoding text, where one "unicode" character
130always represents one screen cell. See L<ROW_t> for a discussion of this format.
131
132=item $string
133
134A perl text string, with an emphasis on I<text>. It can store all unicode
135characters and is to be distinguished with text encoded in a specific
136encoding (often locale-specific) and binary data.
137
138=item $octets
139
140Either binary data or - more common - a text string encoded in a
141locale-specific way.

145=head2 Extension Objects
146
147Very perl extension is a perl class. A separate perl object is created
148for each terminal and each extension and passed as the first parameter to
149hooks. So extensions can use their C<$self> object without having to think
150about other extensions, with the exception of methods and members that
151begin with an underscore character C<_>: these are reserved for internal
152use.
153
154Although it isn't a C<urxvt::term> object, you can call all methods of the
155C<urxvt::term> class on this object.
156
157It has the following methods and data members:
158
159=over 4
160
161=item $urxvt_term = $self->{term}
162
163Returns the C<urxvt::term> object associated with this instance of the
164extension. This member I<must not> be changed in any way.
165
166=item $self->enable ($hook_name => $cb, [$hook_name => $cb..])
167
168Dynamically enable the given hooks (named without the C<on_> prefix) for
169this extension, replacing any previous hook. This is useful when you want
170to overwrite time-critical hooks only temporarily.
171
172=item $self->disable ($hook_name[, $hook_name..])

174Dynamically disable the given hooks.

93member.

170 254
171=item on_tty_activity $term *NYI* 255=item on_osc_seq $term, $string
172 256
173Called whenever the program(s) running in the urxvt window send output. 257Called whenever the B<ESC ] 777 ; string ST> command sequence (OSC =
258operating system command) is processed. Cursor position and other state
259information is up-to-date when this happens. For interoperability, the
260string should start with the extension name and a colon, to distinguish
261it from commands for other extensions, and this might be enforced in the
262future.
263
264Be careful not ever to trust (in a security sense) the data you receive,
265as its source can not easily be controleld (e-mail content, messages from
266other users on the same system etc.).
267
268=item on_add_lines $term, $string
269
270Called whenever text is about to be output, with the text as argument. You
271can filter/change and output the text yourself by returning a true value
272and calling C<< $term->scr_add_lines >> yourself. Please note that this
273might be very slow, however, as your hook is called for B<all> text being
274output.
275
276=item on_tt_write $term, $octets
277
278Called whenever some data is written to the tty/pty and can be used to
279suppress or filter tty input.
280
281=item on_line_update $term, $row
282
283Called whenever a line was updated or changed. Can be used to filter
284screen output (e.g. underline urls or other useless stuff). Only lines
285that are being shown will be filtered, and, due to performance reasons,
286not always immediately.
287
288The row number is always the topmost row of the line if the line spans
289multiple rows.
290
291Please note that, if you change the line, then the hook might get called
292later with the already-modified line (e.g. if unrelated parts change), so
293you cannot just toggle rendition bits, but only set them.
174 294
175=item on_refresh_begin $term 295=item on_refresh_begin $term
176 296
177Called just before the screen gets redrawn. Can be used for overlay 297Called just before the screen gets redrawn. Can be used for overlay

315does focus in processing.

338
339The event is a hash with most values as named by Xlib (see the XEvent
340manpage), with the additional members C<row> and C<col>, which are the row
341and column under the mouse cursor.

1006=item $term->scr_xor_span ($beg_row, $beg_col, $end_row, $end_col[, $rstyle])
1007
1008XORs the rendition values in the given span with the provided value
1009(default: C<RS_RVid>). Useful in refresh hooks to provide effects similar
1010to the selection.
1011
1012=item $term->scr_xor_rect ($beg_row, $beg_col, $end_row, $end_col[, $rstyle1[, $rstyle2]])
1013
1014Similar to C<scr_xor_span>, but xors a rectangle instead. Trailing
1015whitespace will additionally be xored with the C<$rstyle2>, which defaults
1016to C<RS_RVid | RS_Uline>, which removes reverse video again and underlines
1017it instead.

1023=item $term->scr_add_lines ($string)
1024
1025Write the given text string to the screen, as if output by the application
1026running inside the terminal. It may not contain command sequences (escape
1027codes), but is free to use line feeds, carriage returns and tabs. The
1028string is a normal text string, not in locale-dependent encoding.
1029
1030Normally its not a good idea to use this function, as programs might be
1031confused by changes in cursor position or scrolling. Its useful inside a
1032C<on_add_lines> hook, though.
1033
1034=item $term->cmd_parse ($octets)
1035
1036Similar to C<scr_add_lines>, but the argument must be in the
1037locale-specific encoding of the terminal and can contain command sequences
