select urls and complete shell-quoted arguments, which is very convenient, |

233 |
All objects (such as terminals, time watchers etc.) are typical |
234 |
reference-to-hash objects. The hash can be used to store anything you |
235 |
like. All members starting with an underscore (such as \f(CW\*(C`_ptr\*(C'\fR or |
236 |
\&\f(CW\*(C`_hook\*(C'\fR) are reserved for internal uses and \fB\s-1MUST\s0 \s-1NOT\s0\fR be accessed or |
237 |
modified). |
238 |
.PP |
239 |
When objects are destroyed on the \*(C+ side, the perl object hashes are |
240 |
emptied, so its best to store related objects such as time watchers and |
241 |
the like inside the terminal object so they get destroyed as soon as the |
242 |
terminal is destroyed. |
243 |
.PP |
244 |
Argument names also often indicate the type of a parameter. Here are some |
245 |
hints on what they mean: |
246 |
.IP "$text" 4 |
247 |
.IX Item "$text" |
248 |
Rxvt-unicodes special way of encoding text, where one \*(L"unicode\*(R" character |
249 |
always represents one screen cell. See row_t for a discussion of this format. |
250 |
.IP "$string" 4 |
251 |
.IX Item "$string" |
252 |
A perl text string, with an emphasis on \fItext\fR. It can store all unicode |
253 |
characters and is to be distinguished with text encoded in a specific |
254 |
encoding (often locale\-specific) and binary data. |
255 |
.IP "$octets" 4 |

.IX Subsection "Extension Objects" |
261 |
Very perl extension is a perl class. A separate perl object is created |
262 |
for each terminal and each extension and passed as the first parameter to |
263 |
hooks. So extensions can use their \f(CW$self\fR object without having to think |
264 |
about other extensions, with the exception of methods and members that |
265 |
begin with an underscore character \f(CW\*(C`_\*(C'\fR: these are reserved for internal |
266 |
use. |
267 |
.PP |
268 |
Although it isn't a \f(CW\*(C`urxvt::term\*(C'\fR object, you can call all methods of the |
269 |

273 |
.el .IP "$urxvt_term = \f(CW$self\fR\->{term}" 4 |
274 |
.IX Item "$urxvt_term = $self->{term}" |
275 |
Returns the \f(CW\*(C`urxvt::term\*(C'\fR object associated with this instance of the |
276 |
extension. This member \fImust not\fR be changed in any way. |
277 |

.IX Item "$self->enable ($hook_name => $cb, [$hook_name => $cb..])" |
280 |
Dynamically enable the given hooks (named without the \f(CW\*(C`on_\*(C'\fR prefix) for |
281 |
this extension, replacing any previous hook. This is useful when you want |
282 |
to overwrite time-critical hooks only temporarily. |
283 |

284 |

called whenever the relevant event happens. |

301 |
.el .IP "on_init \f(CW$term\fR" 4 |
302 |
.IX Item "on_init $term" |
303 |
Called after a new terminal object has been initialized, but before |
304 |
windows are created or the command gets run. Most methods are unsafe to |
305 |
call or deliver senseless data, as terminal size and other characteristics |
306 |
have not yet been determined. You can safely query and change resources, |
307 |
though. |
308 |
.ie n .IP "on_reset $term" 4 |
309 |
.el .IP "on_reset \f(CW$term\fR" 4 |
310 |
.IX Item "on_reset $term" |
311 |
Called after the screen is \*(L"reset\*(R" for any reason, such as resizing or |
312 |
control sequences. Here is where you can react on changes to size-related |
313 |
variables. |
314 |
.ie n .IP "on_start $term" 4 |
315 |
.el .IP "on_start \f(CW$term\fR" 4 |
316 |
.IX Item "on_start $term" |

Called at the very end of initialisation of a new terminal, just before |
318 |
returning to the mainloop. |
319 |
.ie n .IP "on_sel_make $term\fR, \f(CW$eventtime" 4 |
320 |
.el .IP "on_sel_make \f(CW$term\fR, \f(CW$eventtime\fR" 4 |
321 |
.IX Item "on_sel_make $term, $eventtime" |
322 |
Called whenever a selection has been made by the user, but before the |
323 |
selection text is copied, so changes to the beginning, end or type of the |
324 |
selection will be honored. |
325 |
.Sp |
326 |
Returning a true value aborts selection making by urxvt, in which case you |
327 |
have to make a selection yourself by calling \f(CW\*(C`$term\->selection_grab\*(C'\fR. |
328 |
.ie n .IP "on_sel_grab $term\fR, \f(CW$eventtime" 4 |

330 |
.IX Item "on_sel_grab $term, $eventtime" |
331 |
Called whenever a selection has been copied, but before the selection is |
332 |
requested from the server. The selection text can be queried and changed |
333 |
by calling \f(CW\*(C`$term\->selection\*(C'\fR. |
334 |
.Sp |
335 |
Returning a true value aborts selection grabbing. It will still be hilighted. |
336 |
.ie n .IP "on_sel_extend $term" 4 |
337 |
.el .IP "on_sel_extend \f(CW$term\fR" 4 |
338 |
.IX Item "on_sel_extend $term" |
339 |
Called whenever the user tries to extend the selection (e.g. with a double |
340 |
click) and is either supposed to return false (normal operation), or |
341 |
should extend the selection itelf and return true to suppress the built-in |
342 |
processing. |

Called whenever the view offset changes, i..e the user or program |
349 |
scrolls. Offset \f(CW0\fR means display the normal terminal, positive values |
350 |
show this many lines of scrollback. |

354 |
Called whenever lines scroll out of the terminal area into the scrollback |
355 |
buffer. \f(CW$lines\fR is the number of lines scrolled out and may be larger |
356 |
than the scroll back buffer or the terminal. |
357 |
.Sp |
358 |
It is called before lines are scrolled out (so rows 0 .. min ($lines \- 1, |
