44Miscellaneous selection modifications. 44(More) intelligent selection. This extension tries to be more intelligent
45when the user extends selections (double-click). Right now, it tries to
46select urls and complete shell-quoted arguments, which is very convenient,
47too, if your F<ls> supports C<--quoting-style=shell>.

120Argument names also often indicate the type of a parameter. Here are some

123=over 4
124
125=item $text
126
127Rxvt-unicodes special way of encoding text, where one "unicode" character
128always represents one screen cell. See L<row_t> for a discussion of this format.
129
130=item $string
131
132A perl text string, with an emphasis on I<text>. It can store all unicode
133characters and is to be distinguished with text encoded in a specific
134encoding (often locale-specific) and binary data.
135
136=item $octets

138Either binary data or - more common - a text string encoded in a
139locale-specific way.

143=head2 Extension Objects
144
145Very perl extension is a perl class. A separate perl object is created
146for each terminal and each extension and passed as the first parameter to
147hooks. So extensions can use their C<$self> object without having to think
148about other extensions, with the exception of methods and members that
149begin with an underscore character C<_>: these are reserved for internal
150use.
151
152Although it isn't a C<urxvt::term> object, you can call all methods of the
153C<urxvt::term> class on this object.
154
155It has the following methods and data members:
156
157=over 4
158
159=item $urxvt_term = $self->{term}
160
161Returns the C<urxvt::term> object associated with this instance of the
162extension. This member I<must not> be changed in any way.
163
164=item $self->enable ($hook_name => $cb, [$hook_name => $cb..])
165
166Dynamically enable the given hooks (named without the C<on_> prefix) for
167this extension, replacing any previous hook. This is useful when you want
168to overwrite time-critical hooks only temporarily.
169
170=item $self->disable ($hook_name[, $hook_name..])

172Dynamically disable the given hooks.

97windows are created or the command gets run. 195windows are created or the command gets run. Most methods are unsafe to
196call or deliver senseless data, as terminal size and other characteristics
197have not yet been determined. You can safely query and change resources,

153=item on_tty_activity $term *NYI* 253=item on_osc_seq $term, $string
154 254
155Called whenever the program(s) running in the urxvt window send output. 255Called whenever the B<ESC ] 777 ; string ST> command sequence (OSC =
256operating system command) is processed. Cursor position and other state
257information is up-to-date when this happens. For interoperability, the
258string should start with the extension name and a colon, to distinguish
259it from commands for other extensions, and this might be enforced in the
260future.
261
262Be careful not ever to trust (in a security sense) the data you receive,
263as its source can not easily be controleld (e-mail content, messages from
264other users on the same system etc.).
265
266=item on_add_lines $term, $string
267
268Called whenever text is about to be output, with the text as argument. You
269can filter/change and output the text yourself by returning a true value
270and calling C<< $term->scr_add_lines >> yourself. Please note that this
271might be very slow, however, as your hook is called for B<all> text being
272output.
273
274=item on_tt_write $term, $octets
275
276Called whenever some data is written to the tty/pty and can be used to
277suppress or filter tty input.
278
279=item on_line_update $term, $row
280
281Called whenever a line was updated or changed. Can be used to filter
282screen output (e.g. underline urls or other useless stuff). Only lines
283that are being shown will be filtered, and, due to performance reasons,
284not always immediately.
285
286The row number is always the topmost row of the line if the line spans
287multiple rows.
288
289Please note that, if you change the line, then the hook might get called
290later with the already-modified line (e.g. if unrelated parts change), so
291you cannot just toggle rendition bits, but only set them.
156 292
157=item on_refresh_begin $term 293=item on_refresh_begin $term
158 294
159Called just before the screen gets redrawn. Can be used for overlay 295Called just before the screen gets redrawn. Can be used for overlay

335the hook returns true, then the even will be ignored by rxvt-unicode.
336
337The event is a hash with most values as named by Xlib (see the XEvent
338manpage), with the additional members C<row> and C<col>, which are the row
339and column under the mouse cursor.

978
979=item $term->scr_xor_span ($beg_row, $beg_col, $end_row, $end_col[, $rstyle])
980
981XORs the rendition values in the given span with the provided value
982(default: C<RS_RVid>). Useful in refresh hooks to provide effects similar
983to the selection.
984
985=item $term->scr_xor_rect ($beg_row, $beg_col, $end_row, $end_col[, $rstyle1[, $rstyle2]])
986
987Similar to C<scr_xor_span>, but xors a rectangle instead. Trailing
988whitespace will additionally be xored with the C<$rstyle2>, which defaults
989to C<RS_RVid | RS_Uline>, which removes reverse video again and underlines
990it instead.

996=item $term->scr_add_lines ($string)
997
998Write the given text string to the screen, as if output by the application
999running inside the terminal. It may not contain command sequences (escape
1000codes), but is free to use line feeds, carriage returns and tabs. The
1001string is a normal text string, not in locale-dependent encoding.
1002
1003Normally its not a good idea to use this function, as programs might be
1004confused by changes in cursor position or scrolling. Its useful inside a
1005C<on_add_lines> hook, though.
1006
1007=item $term->cmd_parse ($octets)
1008
1009Similar to C<scr_add_lines>, but the argument must be in the
1010locale-specific encoding of the terminal and can contain command sequences
1011(escape codes) that will be interpreted.
