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,

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.

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.

96Called after a new terminal object has been initialized, but before 188Called after a new terminal object has been initialized, but before
97windows are created or the command gets run. 189windows are created or the command gets run. Most methods are unsafe to
190call or deliver senseless data, as terminal size and other characteristics
191have not yet been determined. You can safely query and change resources,
192though.

152 246
153=item on_tty_activity $term *NYI* 247=item on_osc_seq $term, $string
154 248
155Called 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_tt_write $term, $octets
269
270Called whenever some data is written to the tty/pty and can be used to
271suppress or filter tty input.
272
273=item on_line_update $term, $row
274
275Called whenever a line was updated or changed. Can be used to filter
276screen output (e.g. underline urls or other useless stuff). Only lines
277that are being shown will be filtered, and, due to performance reasons,
278not always immediately.
279
280The row number is always the topmost row of the line if the line spans
281multiple rows.
282
283Please note that, if you change the line, then the hook might get called
284later with the already-modified line (e.g. if unrelated parts change), so
285you cannot just toggle rendition bits, but only set them.
156 286
157=item on_refresh_begin $term 287=item on_refresh_begin $term
158 288
159Called just before the screen gets redrawn. Can be used for overlay 289Called just before the screen gets redrawn. Can be used for overlay
160or similar effects by modify terminal contents in refresh_begin, and 290or similar effects by modify terminal contents in refresh_begin, and

307does focus in processing.

329the hook returns true, then the even will be ignored by rxvt-unicode.
330
331The event is a hash with most values as named by Xlib (see the XEvent
332manpage), with the additional members C<row> and C<col>, which are the row
333and column under the mouse cursor.

951=item $term->scr_xor_span ($beg_row, $beg_col, $end_row, $end_col[, $rstyle])

960whitespace will additionally be xored with the C<$rstyle2>, which defaults

971running inside the terminal. It may not contain command sequences (escape
972codes), but is free to use line feeds, carriage returns and tabs. The
973string is a normal text string, not in locale-dependent encoding.
974
975Normally its not a good idea to use this function, as programs might be
976confused by changes in cursor position or scrolling. Its useful inside a
977C<on_add_lines> hook, though.

980
981Similar to C<scr_add_lines>, but the argument must be in the

993Replaces the event mask of the pty watcher by the given event mask. Can
