229     .IX Subsection "General API Considerations"
230     All objects (such as terminals, time watchers etc.) are typical
231     reference-to-hash objects. The hash can be used to store anything you
232     like. All members starting with an underscore (such as \f(CW\*(C`_ptr\*(C'\fR or
233 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
234 root 1.3 modified).
235     .PP
236     When objects are destroyed on the \*(C+ side, the perl object hashes are
237     emptied, so its best to store related objects such as time watchers and
238     the like inside the terminal object so they get destroyed as soon as the
239     terminal is destroyed.
240 root 1.14 .PP
241     Argument names also often indicate the type of a parameter. Here are some
242     hints on what they mean:
243     .IP "$text" 4
244     .IX Item "$text"
245     Rxvt-unicodes special way of encoding text, where one \*(L"unicode\*(R" character
246     always represents one screen cell. See row_t for a discussion of this format.
247     .IP "$string" 4
248     .IX Item "$string"
249     A perl text string, with an emphasis on \fItext\fR. It can store all unicode
250     characters and is to be distinguished with text encoded in a specific
251     encoding (often locale\-specific) and binary data.
252     .IP "$octets" 4
253     .IX Item "$octets"
254     Either binary data or \- more common \- a text string encoded in a
255     locale-specific way.
256 root 1.19 .Sh "Extension Objects"
257     .IX Subsection "Extension Objects"
258     Very perl extension is a perl class. A separate perl object is created
259     for each terminal and each extension and passed as the first parameter to
260     hooks. So extensions can use their \f(CW$self\fR object without having to think
261     about other extensions, with the exception of methods and members that
262     begin with an underscore character \f(CW\*(C`_\*(C'\fR: these are reserved for internal
263     use.
264     .PP
265     Although it isn't a \f(CW\*(C`urxvt::term\*(C'\fR object, you can call all methods of the
266     \&\f(CW\*(C`urxvt::term\*(C'\fR class on this object.

270     .el .IP "$urxvt_term = \f(CW$self\fR\->{term}" 4
271     .IX Item "$urxvt_term = $self->{term}"
272     Returns the \f(CW\*(C`urxvt::term\*(C'\fR object associated with this instance of the
273     extension. This member \fImust not\fR be changed in any way.
274     .ie n .IP "$self\->enable ($hook_name => $cb\fR, [$hook_name => \f(CW$cb..])" 4
275     .el .IP "$self\->enable ($hook_name => \f(CW$cb\fR, [$hook_name => \f(CW$cb\fR..])" 4
276     .IX Item "$self->enable ($hook_name => $cb, [$hook_name => $cb..])"
277     Dynamically enable the given hooks (named without the \f(CW\*(C`on_\*(C'\fR prefix) for
278     this extension, replacing any previous hook. This is useful when you want
279     to overwrite time-critical hooks only temporarily.
280     .ie n .IP "$self\->disable ($hook_name[, $hook_name..])" 4
281     .el .IP "$self\->disable ($hook_name[, \f(CW$hook_name\fR..])" 4
282     .IX Item "$self->disable ($hook_name[, $hook_name..])"
283     Dynamically disable the given hooks.

298     .el .IP "on_init \f(CW$term\fR" 4
299     .IX Item "on_init $term"
300     Called after a new terminal object has been initialized, but before
301 root 1.14 windows are created or the command gets run. Most methods are unsafe to
302     call or deliver senseless data, as terminal size and other characteristics
303     have not yet been determined. You can safely query and change resources,
304     though.
305 root 1.1 .ie n .IP "on_reset $term" 4
306     .el .IP "on_reset \f(CW$term\fR" 4
307     .IX Item "on_reset $term"
308     Called after the screen is \*(L"reset\*(R" for any reason, such as resizing or
309     control sequences. Here is where you can react on changes to size-related
310     variables.
311     .ie n .IP "on_start $term" 4
312     .el .IP "on_start \f(CW$term\fR" 4
313     .IX Item "on_start $term"
314     Called at the very end of initialisation of a new terminal, just before
315     returning to the mainloop.
316     .ie n .IP "on_sel_make $term\fR, \f(CW$eventtime" 4
317     .el .IP "on_sel_make \f(CW$term\fR, \f(CW$eventtime\fR" 4
318     .IX Item "on_sel_make $term, $eventtime"
319     Called whenever a selection has been made by the user, but before the
320     selection text is copied, so changes to the beginning, end or type of the
321     selection will be honored.
322     .Sp
323     Returning a true value aborts selection making by urxvt, in which case you
324     have to make a selection yourself by calling \f(CW\*(C`$term\->selection_grab\*(C'\fR.

327     .IX Item "on_sel_grab $term, $eventtime"
328     Called whenever a selection has been copied, but before the selection is
329     requested from the server. The selection text can be queried and changed
330     by calling \f(CW\*(C`$term\->selection\*(C'\fR.
331     .Sp
332     Returning a true value aborts selection grabbing. It will still be hilighted.

334     .el .IP "on_sel_extend \f(CW$term\fR" 4
335     .IX Item "on_sel_extend $term"
336     Called whenever the user tries to extend the selection (e.g. with a double
337     click) and is either supposed to return false (normal operation), or
338     should extend the selection itelf and return true to suppress the built-in
339     processing.
340     .Sp
341     See the \fIselection\fR example extension.

344     .IX Item "on_view_change $term, $offset"
345     Called whenever the view offset changes, i..e the user or program
346     scrolls. Offset \f(CW0\fR means display the normal terminal, positive values
347     show this many lines of scrollback.
348     .ie n .IP "on_scroll_back $term\fR, \f(CW$lines\fR, \f(CW$saved" 4

350     .IX Item "on_scroll_back $term, $lines, $saved"
351     Called whenever lines scroll out of the terminal area into the scrollback
352     buffer. \f(CW$lines\fR is the number of lines scrolled out and may be larger
353     than the scroll back buffer or the terminal.
354     .Sp
355     It is called before lines are scrolled out (so rows 0 .. min ($lines \- 1,
356     \&\f(CW$nrow\fR \- 1) represent the lines to be scrolled out). \f(CW$saved\fR is the total
357     number of lines that will be in the scrollback buffer.
358 root 1.11 .ie n .IP "on_osc_seq $term\fR, \f(CW$string" 4
359     .el .IP "on_osc_seq \f(CW$term\fR, \f(CW$string\fR" 4
360     .IX Item "on_osc_seq $term, $string"
361     Called whenever the \fB\s-1ESC\s0 ] 777 ; string \s-1ST\s0\fR command sequence (\s-1OSC\s0 =
362     operating system command) is processed. Cursor position and other state
363     information is up-to-date when this happens. For interoperability, the
364     string should start with the extension name and a colon, to distinguish
365     it from commands for other extensions, and this might be enforced in the
366     future.
367     .Sp
368     Be careful not ever to trust (in a security sense) the data you receive,
369     as its source can not easily be controleld (e\-mail content, messages from
370     other users on the same system etc.).
371 root 1.14 .ie n .IP "on_add_lines $term\fR, \f(CW$string" 4
372     .el .IP "on_add_lines \f(CW$term\fR, \f(CW$string\fR" 4
373     .IX Item "on_add_lines $term, $string"
374     Called whenever text is about to be output, with the text as argument. You
375     can filter/change and output the text yourself by returning a true value
376     and calling \f(CW\*(C`$term\->scr_add_lines\*(C'\fR yourself. Please note that this
377     might be very slow, however, as your hook is called for \fBall\fR text being
378     output.
