44Miscellaneous selection modifications. 44Intelligent selection. This extension tries to be more intelligent when
45the user extends selections (double-click). Right now, it tries to select
46urls and complete shell-quoted arguments, which is very convenient, too,

111=item $text
112
113Rxvt-unicodes special way of encoding text, where one "unicode" character
114always represents one screen cell. See L<row_t> for a discussion of this format.
115
116=item $string
117
118A perl text string, with an emphasis on I<text>. It can store all unicode
119characters and is to be distinguished with text encoded in a specific
120encoding (often locale-specific) and binary data.
121
122=item $octets

133
134The first argument passed to them is an object private to each terminal
135and extension package. You can call all C<urxvt::term> methods on it, but
136its not a real C<urxvt::term> object. Instead, the real C<urxvt::term>
137object that is shared between all packages is stored in the C<term>
138member. It is, however, blessed intot he package of the extension script,
139so for all practical purposes you can treat an extension script as a class.
85 140

96Called after a new terminal object has been initialized, but before 151Called after a new terminal object has been initialized, but before
97windows are created or the command gets run. 152windows are created or the command gets run. Most methods are unsafe to
153call or deliver senseless data, as terminal size and other characteristics
154have not yet been determined. You can safely query and change resources,
155though.

130focus in processing. 188click) and is either supposed to return false (normal operation), or

153=item on_tty_activity $term *NYI* 210=item on_tty_activity $term *NYI*
154 211
155Called whenever the program(s) running in the urxvt window send output. 212Called whenever the program(s) running in the urxvt window send output.
213
214=item on_osc_seq $term, $string
215
216Called whenever the B<ESC ] 777 ; string ST> command sequence (OSC =
217operating system command) is processed. Cursor position and other state
218information is up-to-date when this happens. For interoperability, the
219string should start with the extension name and a colon, to distinguish
220it from commands for other extensions, and this might be enforced in the
221future.
222
223Be careful not ever to trust (in a security sense) the data you receive,
224as its source can not easily be controleld (e-mail content, messages from
225other users on the same system etc.).
226
227=item on_add_lines $term, $string
228
229Called whenever text is about to be output, with the text as argument. You
230can filter/change and output the text yourself by returning a true value
231and calling C<< $term->scr_add_lines >> yourself. Please note that this
232might be very slow, however, as your hook is called for B<all> text being
233output.
234
235=item on_line_update $term, $row
236
237Called whenever a line was updated or changed. Can be used to filter
238screen output (e.g. underline urls or other useless stuff). Only lines
239that are being shown will be filtered, and, due to performance reasons,
240not always immediately.
241
242The row number is always the topmost row of the line if the line spans
243multiple rows.
244
245Please note that, if you change the line, then the hook might get called
246later with the already-modified line (e.g. if unrelated parts change), so
247you cannot just toggle rendition bits, but only set them.
156 248
157=item on_refresh_begin $term 249=item on_refresh_begin $term
158 250
159Called just before the screen gets redrawn. Can be used for overlay 251Called just before the screen gets redrawn. Can be used for overlay
160or similar effects by modify terminal contents in refresh_begin, and 252or similar effects by modify terminal contents in refresh_begin, and
169 261

171C<perl:string> action bound to it (see description of the B<keysym> 263C<perl:string> action bound to it (see description of the B<keysym>

266=item on_focus_in $term
267
268Called whenever the window gets the keyboard focus, before rxvt-unicode
269does focus in processing.
270
271=item on_focus_out $term
272
273Called wheneever the window loses keyboard focus, before rxvt-unicode does
274focus out processing.

290Called whenever the corresponding X event is received for the terminal If
291the hook returns true, then the even will be ignored by rxvt-unicode.
292
293The event is a hash with most values as named by Xlib (see the XEvent
294manpage), with the additional members C<row> and C<col>, which are the row
295and column under the mouse cursor.

356=head2 RENDITION
357
358Rendition bitsets contain information about colour, font, font styles and
359similar information for each screen cell.
360
361The following "macros" deal with changes in rendition sets. You should
362never just create a bitset, you should always modify an existing one,
363as they contain important information required for correct operation of
364rxvt-unicode.
