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.

171=item on_tty_activity $term *NYI* 247=item on_osc_seq $term, $string
172 248
173Called whenever the program(s) running in the urxvt window send output. 249Called whenever the B<ESC ] 777 ; string ST> command sequence (OSC =
250operating system command) is processed. Cursor position and other state
251information is up-to-date when this happens. For interoperability, the
252string should start with the extension name and a colon, to distinguish
253it from commands for other extensions, and this might be enforced in the
254future.
255
256Be careful not ever to trust (in a security sense) the data you receive,
257as its source can not easily be controleld (e-mail content, messages from
258other users on the same system etc.).
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.
174 281
175=item on_refresh_begin $term 282=item on_refresh_begin $term
176 283
177Called just before the screen gets redrawn. Can be used for overlay 284Called just before the screen gets redrawn. Can be used for overlay

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
