112
113A perl text string, with an emphasis on I<text>. It can store all unicode
114characters and is to be distinguished with text encoded in a specific

189 221
222=item on_add_lines $term, $string
223
224Called whenever text is about to be output, with the text as argument. You
225can filter/change and output the text yourself by returning a true value
226and calling C<< $term->scr_add_lines >> yourself. Please note that this
227might be very slow, however, as your hook is called for B<all> text being
228output.
229
230=item on_line_update $term, $row
231
232Called whenever a line was updated or changed. Can be used to filter
233screen output (e.g. underline urls or other useless stuff). Only lines
234that are being shown will be filtered, and, due to performance reasons,
235not always immediately.
236
237The row number is always the topmost row of the line if the line spans
238multiple rows.
239
240Please note that, if you change the line, then the hook might get called
241later with the already-modified line (e.g. if unrelated parts change), so
242you cannot just toggle rendition bits, but only set them.

264does focus in processing.

286the hook returns true, then the even will be ignored by rxvt-unicode.
287
288The event is a hash with most values as named by Xlib (see the XEvent
289manpage), with the additional members C<row> and C<col>, which are the row
290and column under the mouse cursor.
