179 urls and complete shell-quoted arguments, which is very convenient, too,
180 if your \fIls\fR supports \f(CW\*(C`\-\-quoting\-style=shell\*(C'\fR.

227 overlays or changes.
228 .Sh "General \s-1API\s0 Considerations"
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 \&\f(CW\*(C`_hook\*(C'\fR) are reserved for internal uses and \fB\s-1MUST\s0 \s-1NOT\s0\fR be accessed or
234 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 .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 .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$self\fR object without having to think
261 about other extensions, with the exception of methods and members that
262 begin with an underscore character \f(CW\*(C`_\*(C'\fR: these are reserved for internal
263 use.
264 .PP
265 Although it isn't a \f(CW\*(C`urxvt::term\*(C'\fR object, you can call all methods of the
266 \&\f(CW\*(C`urxvt::term\*(C'\fR class on this object.
267 .PP
268 It has the following methods and data members:
269 .ie n .IP "$urxvt_term = $self\->{term}" 4
270 .el .IP "$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.
284 .Sh "Hooks"
285 .IX Subsection "Hooks"
286 The following subroutines can be declared in extension files, and will be
287 called whenever the relevant event happens.
288 .PP
289 The first argument passed to them is an extension oject as described in
290 the in the \f(CW\*(C`Extension Objects\*(C'\fR section.
291 .PP
292 \&\fBAll\fR of these hooks must return a boolean value. If it is true, then the
293 event counts as being \fIconsumed\fR, and the invocation of other hooks is
294 skipped, and the relevant action might not be carried out by the \*(C+ code.
295 .PP
296 \&\fIWhen in doubt, return a false value (preferably \f(CI\*(C`()\*(C'\fI).\fR
297 .ie n .IP "on_init $term" 4
298 .el .IP "on_init \f(CW$term\fR" 4
299 .IX Item "on_init $term"
300 Called after a new terminal object has been initialized, but before
301 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 .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.
325 .ie n .IP "on_sel_grab $term\fR, \f(CW$eventtime" 4
326 .el .IP "on_sel_grab \f(CW$term\fR, \f(CW$eventtime\fR" 4
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.
333 .ie n .IP "on_sel_extend $term" 4
334 .el .IP "on_sel_extend \f(CW$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.
342 .ie n .IP "on_view_change $term\fR, \f(CW$offset" 4
343 .el .IP "on_view_change \f(CW$term\fR, \f(CW$offset\fR" 4
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$saved" 4
349 .el .IP "on_scroll_back \f(CW$term\fR, \f(CW$lines\fR, \f(CW$saved\fR" 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 .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 .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.
379 .ie n .IP "on_tt_write $term\fR, \f(CW$octets" 4
380 .el .IP "on_tt_write \f(CW$term\fR, \f(CW$octets\fR" 4
381 .IX Item "on_tt_write $term, $octets"
382 Called whenever some data is written to the tty/pty and can be used to
383 suppress or filter tty input.
384 .ie n .IP "on_line_update $term\fR, \f(CW$row" 4
385 .el .IP "on_line_update \f(CW$term\fR, \f(CW$row\fR" 4
386 .IX Item "on_line_update $term, $row"
387 Called whenever a line was updated or changed. Can be used to filter
388 screen output (e.g. underline urls or other useless stuff). Only lines
389 that are being shown will be filtered, and, due to performance reasons,
390 not always immediately.
391 .Sp
392 The row number is always the topmost row of the line if the line spans
393 multiple rows.
394 .Sp
395 Please note that, if you change the line, then the hook might get called
396 later with the already-modified line (e.g. if unrelated parts change), so
397 you cannot just toggle rendition bits, but only set them.
398 .ie n .IP "on_refresh_begin $term" 4
399 .el .IP "on_refresh_begin \f(CW$term\fR" 4
400 .IX Item "on_refresh_begin $term"
401 Called just before the screen gets redrawn. Can be used for overlay
402 or similar effects by modify terminal contents in refresh_begin, and
403 restoring them in refresh_end. The built-in overlay and selection display
404 code is run after this hook, and takes precedence.
405 .ie n .IP "on_refresh_end $term" 4
406 .el .IP "on_refresh_end \f(CW$term\fR" 4
407 .IX Item "on_refresh_end $term"

409 .ie n .IP "on_keyboard_command $term\fR, \f(CW$string" 4
410 .el .IP "on_keyboard_command \f(CW$term\fR, \f(CW$string\fR" 4
411 .IX Item "on_keyboard_command $term, $string"
412 Called whenever the user presses a key combination that has a
413 \&\f(CW\*(C`perl:string\*(C'\fR action bound to it (see description of the \fBkeysym\fR
414 resource in the @@RXVT_NAME@@(1) manpage).
415 .ie n .IP "on_focus_in $term" 4
416 .el .IP "on_focus_in \f(CW$term\fR" 4
417 .IX Item "on_focus_in $term"
