109always represents one screen cell. See L<row_t> for a discussion of this format.
110
111=item $string
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
115encoding (often locale-specific) and binary data.

218Be careful not ever to trust (in a security sense) the data you receive,
219as its source can not easily be controleld (e-mail content, messages from
220other users on the same system etc.).
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.

262
263Called whenever the window gets the keyboard focus, before rxvt-unicode
264does focus in processing.
265

267
268Called wheneever the window loses keyboard focus, before rxvt-unicode does
269focus out processing.

285Called whenever the corresponding X event is received for the terminal If
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.
