178 root 1.25 when the user extends selections (double\-click and further clicks). Right

210 root 1.25 by a hotkey (default: \f(CW\*(C`M\-s\*(C'\fR). While in search mode, normal terminal
211     input/output is suspended and a regex is displayed at the bottom of the

218     was started, while \f(CW\*(C`Enter\*(C'\fR or \f(CW\*(C`Return\*(C'\fR stay at the current position and

242 root 1.3 .Sh "General \s-1API\s0 Considerations"
243     .IX Subsection "General API Considerations"
244     All objects (such as terminals, time watchers etc.) are typical
245     reference-to-hash objects. The hash can be used to store anything you
246     like. All members starting with an underscore (such as \f(CW\*(C`_ptr\*(C'\fR or
247 root 1.9 \&\f(CW\*(C`_hook\*(C'\fR) are reserved for internal uses and \fB\s-1MUST\s0 \s-1NOT\s0\fR be accessed or
248 root 1.3 modified).
249     .PP
250     When objects are destroyed on the \*(C+ side, the perl object hashes are
251     emptied, so its best to store related objects such as time watchers and
252     the like inside the terminal object so they get destroyed as soon as the
253     terminal is destroyed.
254 root 1.14 .PP
255     Argument names also often indicate the type of a parameter. Here are some
256     hints on what they mean:
257     .IP "$text" 4
258     .IX Item "$text"
259     Rxvt-unicodes special way of encoding text, where one \*(L"unicode\*(R" character
260 root 1.23 always represents one screen cell. See ROW_t for a discussion of this format.
261 root 1.14 .IP "$string" 4
262     .IX Item "$string"
263     A perl text string, with an emphasis on \fItext\fR. It can store all unicode
264     characters and is to be distinguished with text encoded in a specific
265     encoding (often locale\-specific) and binary data.
266     .IP "$octets" 4
267     .IX Item "$octets"
268     Either binary data or \- more common \- a text string encoded in a
269     locale-specific way.
270 root 1.19 .Sh "Extension Objects"
271     .IX Subsection "Extension Objects"
272     Very perl extension is a perl class. A separate perl object is created
273     for each terminal and each extension and passed as the first parameter to
274     hooks. So extensions can use their \f(CW$self\fR object without having to think
275     about other extensions, with the exception of methods and members that
276     begin with an underscore character \f(CW\*(C`_\*(C'\fR: these are reserved for internal
277     use.
278     .PP
279     Although it isn't a \f(CW\*(C`urxvt::term\*(C'\fR object, you can call all methods of the
280     \&\f(CW\*(C`urxvt::term\*(C'\fR class on this object.

284     .el .IP "$urxvt_term = \f(CW$self\fR\->{term}" 4
285     .IX Item "$urxvt_term = $self->{term}"
286     Returns the \f(CW\*(C`urxvt::term\*(C'\fR object associated with this instance of the
287     extension. This member \fImust not\fR be changed in any way.

290     .IX Item "$self->enable ($hook_name => $cb, [$hook_name => $cb..])"
291     Dynamically enable the given hooks (named without the \f(CW\*(C`on_\*(C'\fR prefix) for
292     this extension, replacing any previous hook. This is useful when you want
293     to overwrite time-critical hooks only temporarily.
294     .ie n .IP "$self\->disable ($hook_name[, $hook_name..])" 4
295     .el .IP "$self\->disable ($hook_name[, \f(CW$hook_name\fR..])" 4

312     .el .IP "on_init \f(CW$term\fR" 4
313     .IX Item "on_init $term"
314     Called after a new terminal object has been initialized, but before
315 root 1.14 windows are created or the command gets run. Most methods are unsafe to
316     call or deliver senseless data, as terminal size and other characteristics
317     have not yet been determined. You can safely query and change resources,
318     though.
319 root 1.1 .ie n .IP "on_reset $term" 4
320     .el .IP "on_reset \f(CW$term\fR" 4
321     .IX Item "on_reset $term"
322     Called after the screen is \*(L"reset\*(R" for any reason, such as resizing or
323     control sequences. Here is where you can react on changes to size-related
324     variables.

331     .el .IP "on_sel_make \f(CW$term\fR, \f(CW$eventtime\fR" 4
332     .IX Item "on_sel_make $term, $eventtime"
333     Called whenever a selection has been made by the user, but before the
334     selection text is copied, so changes to the beginning, end or type of the
335     selection will be honored.
336     .Sp
337     Returning a true value aborts selection making by urxvt, in which case you
338     have to make a selection yourself by calling \f(CW\*(C`$term\->selection_grab\*(C'\fR.

343     requested from the server. The selection text can be queried and changed
344     by calling \f(CW\*(C`$term\->selection\*(C'\fR.
345     .Sp

348     .el .IP "on_sel_extend \f(CW$term\fR" 4
349     .IX Item "on_sel_extend $term"
350     Called whenever the user tries to extend the selection (e.g. with a double
351     click) and is either supposed to return false (normal operation), or
352     should extend the selection itelf and return true to suppress the built-in
353 root 1.25 processing. This can happen multiple times, as long as the callback
354     returns true, it will be called on every further click by the user and is
355     supposed to enlarge the selection more and more, if possible.

368     buffer. \f(CW$lines\fR is the number of lines scrolled out and may be larger
369     than the scroll back buffer or the terminal.
370     .Sp
371     It is called before lines are scrolled out (so rows 0 .. min ($lines \- 1,
