96Argument names also often indicate the type of a parameter. Here are some
97hints on what they mean:

100
101=item $text
102
103Rxvt-unicodes special way of encoding text, where one "unicode" character
104always represents one screen cell. See L<row_t> for a discussion of this format.
105
106=item $string
107
108A perl text string, with an emphasis on I<text>. It can store all unicode
109characters and is to be distinguished with text encoded in a specific
110encoding (often locale-specific) and binary data.
111
112=item $octets
113
114Either binary data or - more common - a text string encoded in a
115locale-specific way.

124The first argument passed to them is an object private to each terminal
125and extension package. You can call all C<urxvt::term> methods on it, but
126its not a real C<urxvt::term> object. Instead, the real C<urxvt::term>
127object that is shared between all packages is stored in the C<term>
128member.

99Called after a new terminal object has been initialized, but before 140Called after a new terminal object has been initialized, but before
100windows are created or the command gets run. 141windows are created or the command gets run. Most methods are unsafe to
142call or deliver senseless data, as terminal size and other characteristics
143have not yet been determined. You can safely query and change resources,
144though.

166 210
167Called whenever the program(s) running in the urxvt window send output. 211Called whenever the program(s) running in the urxvt window send output.
168 212
213=item on_osc_seq $term, $string
214
215Called whenever the B<ESC ] 777 ; string ST> command sequence (OSC =
216operating system command) is processed. Cursor position and other state
217information is up-to-date when this happens. For interoperability, the
218string should start with the extension name and a colon, to distinguish
219it from commands for other extensions, and this might be enforced in the
220future.
221
222Be careful not ever to trust (in a security sense) the data you receive,
223as its source can not easily be controleld (e-mail content, messages from
224other users on the same system etc.).
225
226=item on_add_lines $term, $string
227
228Called whenever text is about to be output, with the text as argument. You
229can filter/change and output the text yourself by returning a true value
230and calling C<< $term->scr_add_lines >> yourself. Please note that this
231might be very slow, however, as your hook is called for B<all> text being
232output.
233
234=item on_line_update $term, $row
235
236Called whenever a line was updated or changed. Can be used to filter
237screen output (e.g. underline urls or other useless stuff). Only lines
238that are being shown will be filtered, and, due to performance reasons,
239not always immediately.
240
241The row number is always the topmost row of the line if the line spans
242multiple rows.
243
244Please note that, if you change the line, then the hook might get called
245later with the already-modified line (e.g. if unrelated parts change), so
246you cannot just toggle rendition bits, but only set them.
247
169=item on_refresh_begin $term 248=item on_refresh_begin $term
170 249
171Called just before the screen gets redrawn. Can be used for overlay 250Called just before the screen gets redrawn. Can be used for overlay
172or similar effects by modify terminal contents in refresh_begin, and 251or similar effects by modify terminal contents in refresh_begin, and

275Called whenever the corresponding X event is received for the terminal If
276the hook returns true, then the even will be ignored by rxvt-unicode.
277
278The event is a hash with most values as named by Xlib (see the XEvent
279manpage), with the additional members C<row> and C<col>, which are the row
280and column under the mouse cursor.

306Creates a new terminal, very similar as if you had started it with
307C<system $binfile, arg...>. Croaks (and probably outputs an error message)
308if the new instance couldn't be created. Returns C<undef> if the new
309instance didn't initialise perl, and the terminal object otherwise. The
