114Argument names also often indicate the type of a parameter. Here are some
115hints on what they mean:

118
119=item $text
120
121Rxvt-unicodes special way of encoding text, where one "unicode" character
122always represents one screen cell. See L<row_t> for a discussion of this format.
123
124=item $string
125
126A perl text string, with an emphasis on I<text>. It can store all unicode
127characters and is to be distinguished with text encoded in a specific
128encoding (often locale-specific) and binary data.
129
130=item $octets
131
132Either binary data or - more common - a text string encoded in a
133locale-specific way.

136
137=head2 Extension Objects
138
139Very perl extension is a perl class. A separate perl object is created
140for each terminal and each extension and passed as the first parameter to
141hooks. So extensions can use their C<$self> object without having to think
142about other extensions, with the exception of methods and members that
143begin with an underscore character C<_>: these are reserved for internal
144use.
145
146Although it isn't a C<urxvt::term> object, you can call all methods of the
147C<urxvt::term> class on this object.
148
149It has the following methods and data members:
150
151=over 4
152
153=item $urxvt_term = $self->{term}
154
155Returns the C<urxvt::term> object associated with this instance of the
156extension. This member I<must not> be changed in any way.
157
158=item $self->enable ($hook_name => $cb, [$hook_name => $cb..])
159
160Dynamically enable the given hooks (named without the C<on_> prefix) for
161this extension, replacing any previous hook. This is useful when you want
162to overwrite time-critical hooks only temporarily.
163
164=item $self->disable ($hook_name[, $hook_name..])
165
166Dynamically disable the given hooks.

189 259
260=item on_add_lines $term, $string
261
262Called whenever text is about to be output, with the text as argument. You
263can filter/change and output the text yourself by returning a true value
264and calling C<< $term->scr_add_lines >> yourself. Please note that this
265might be very slow, however, as your hook is called for B<all> text being
266output.
267
268=item on_line_update $term, $row
269
270Called whenever a line was updated or changed. Can be used to filter
271screen output (e.g. underline urls or other useless stuff). Only lines
272that are being shown will be filtered, and, due to performance reasons,
273not always immediately.
274
275The row number is always the topmost row of the line if the line spans
276multiple rows.
277
278Please note that, if you change the line, then the hook might get called
279later with the already-modified line (e.g. if unrelated parts change), so
280you cannot just toggle rendition bits, but only set them.

324the hook returns true, then the even will be ignored by rxvt-unicode.
325
326The event is a hash with most values as named by Xlib (see the XEvent
327manpage), with the additional members C<row> and C<col>, which are the row
328and column under the mouse cursor.

955whitespace will additionally be xored with the C<$rstyle2>, which defaults
956to C<RS_RVid | RS_Uline>, which removes reverse video again and underlines

965Write the given text string to the screen, as if output by the application
966running inside the terminal. It may not contain command sequences (escape
967codes), but is free to use line feeds, carriage returns and tabs. The
968string is a normal text string, not in locale-dependent encoding.
969
970Normally its not a good idea to use this function, as programs might be
971confused by changes in cursor position or scrolling. Its useful inside a
972C<on_add_lines> hook, though.

976Similar to C<scr_add_lines>, but the argument must be in the
