159 .PP
160 Scripts are compiled in a 'use strict' and 'use utf8' environment, and

178 when the user extends selections (double\-click). Right now, it tries to
179 select urls and complete shell-quoted arguments, which is very convenient,
180 too, if your \fIls\fR supports \f(CW\*(C`\-\-quoting\-style=shell\*(C'\fR.

231 .Sh "General \s-1API\s0 Considerations"
232 .IX Subsection "General API Considerations"
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 "$octets" 4
256 .IX Item "$octets"
257 Either binary data or \- more common \- a text string encoded in a
258 locale-specific way.
259 .Sh "Extension Objects"
260 .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$self\fR object without having to think
264 about other extensions, with the exception of methods and members that
265 begin with an underscore character \f(CW\*(C`_\*(C'\fR: these are reserved for internal
266 use.
267 .PP
268 Although it isn't a \f(CW\*(C`urxvt::term\*(C'\fR object, you can call all methods of the
269 \&\f(CW\*(C`urxvt::term\*(C'\fR class on this object.
270 .PP
271 It has the following methods and data members:
272 .ie n .IP "$urxvt_term = $self\->{term}" 4
273 .el .IP "$urxvt_term = \f(CW$self\fR\->{term}" 4
274 .IX Item "$urxvt_term = $self->{term}"
275 Returns the \f(CW\*(C`urxvt::term\*(C'\fR object associated with this instance of the
276 extension. This member \fImust not\fR be changed in any way.
277 .ie n .IP "$self\->enable ($hook_name => $cb\fR, [$hook_name => \f(CW$cb..])" 4
278 .el .IP "$self\->enable ($hook_name => \f(CW$cb\fR, [$hook_name => \f(CW$cb\fR..])" 4
279 .IX Item "$self->enable ($hook_name => $cb, [$hook_name => $cb..])"
280 Dynamically enable the given hooks (named without the \f(CW\*(C`on_\*(C'\fR prefix) for
281 this extension, replacing any previous hook. This is useful when you want
282 to overwrite time-critical hooks only temporarily.
283 .ie n .IP "$self\->disable ($hook_name[, $hook_name..])" 4
284 .el .IP "$self\->disable ($hook_name[, \f(CW$hook_name\fR..])" 4
285 .IX Item "$self->disable ($hook_name[, $hook_name..])"
286 Dynamically disable the given hooks.
287 .Sh "Hooks"
288 .IX Subsection "Hooks"
289 The following subroutines can be declared in extension files, and will be
290 called whenever the relevant event happens.
291 .PP
292 The first argument passed to them is an extension oject as described in
293 the in the \f(CW\*(C`Extension Objects\*(C'\fR section.
294 .PP
295 \&\fBAll\fR of these hooks must return a boolean value. If it is true, then the
296 event counts as being \fIconsumed\fR, and the invocation of other hooks is
297 skipped, and the relevant action might not be carried out by the \*(C+ code.
298 .PP
299 \&\fIWhen in doubt, return a false value (preferably \f(CI\*(C`()\*(C'\fI).\fR
300 .ie n .IP "on_init $term" 4
301 .el .IP "on_init \f(CW$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"
317 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
329 .el .IP "on_sel_grab \f(CW$term\fR, \f(CW$eventtime\fR" 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.
343 .Sp
344 See the \fIselection\fR example extension.
345 .ie n .IP "on_view_change $term\fR, \f(CW$offset" 4
346 .el .IP "on_view_change \f(CW$term\fR, \f(CW$offset\fR" 4
347 .IX Item "on_view_change $term, $offset"
348 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.
351 .ie n .IP "on_scroll_back $term\fR, \f(CW$lines\fR, \f(CW$saved" 4
352 .el .IP "on_scroll_back \f(CW$term\fR, \f(CW$lines\fR, \f(CW$saved\fR" 4
353 .IX Item "on_scroll_back $term, $lines, $saved"
354 Called whenever lines scroll out of the terminal area into the scrollback
355 buffer. \f(CW$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 ($lines \- 1,
359 \&\f(CW$nrow\fR \- 1) represent the lines to be scrolled out). \f(CW$saved\fR is the total
360 number of lines that will be in the scrollback buffer.
361 .ie n .IP "on_osc_seq $term\fR, \f(CW$string" 4
362 .el .IP "on_osc_seq \f(CW$term\fR, \f(CW$string\fR" 4
363 .IX Item "on_osc_seq $term, $string"
364 Called whenever the \fB\s-1ESC\s0 ] 777 ; string \s-1ST\s0\fR command sequence (\s-1OSC\s0 =
365 operating system command) is processed. Cursor position and other state
366 information is up-to-date when this happens. For interoperability, the
367 string should start with the extension name and a colon, to distinguish
368 it from commands for other extensions, and this might be enforced in the
369 future.
370 .Sp
371 Be careful not ever to trust (in a security sense) the data you receive,
372 as its source can not easily be controleld (e\-mail content, messages from
373 other users on the same system etc.).
374 .ie n .IP "on_add_lines $term\fR, \f(CW$string" 4
375 .el .IP "on_add_lines \f(CW$term\fR, \f(CW$string\fR" 4
376 .IX Item "on_add_lines $term, $string"
377 Called whenever text is about to be output, with the text as argument. You
378 can filter/change and output the text yourself by returning a true value
379 and calling \f(CW\*(C`$term\->scr_add_lines\*(C'\fR yourself. Please note that this
380 might be very slow, however, as your hook is called for \fBall\fR text being
381 output.
382 .ie n .IP "on_tt_write $term\fR, \f(CW$octets" 4
383 .el .IP "on_tt_write \f(CW$term\fR, \f(CW$octets\fR" 4
384 .IX Item "on_tt_write $term, $octets"
385 Called whenever some data is written to the tty/pty and can be used to
386 suppress or filter tty input.
387 .ie n .IP "on_line_update $term\fR, \f(CW$row" 4
388 .el .IP "on_line_update \f(CW$term\fR, \f(CW$row\fR" 4
389 .IX Item "on_line_update $term, $row"
390 Called whenever a line was updated or changed. Can be used to filter
391 screen output (e.g. underline urls or other useless stuff). Only lines
392 that are being shown will be filtered, and, due to performance reasons,
393 not always immediately.
394 .Sp
395 The row number is always the topmost row of the line if the line spans
396 multiple rows.
397 .Sp
398 Please note that, if you change the line, then the hook might get called
399 later with the already-modified line (e.g. if unrelated parts change), so
400 you cannot just toggle rendition bits, but only set them.
401 .ie n .IP "on_refresh_begin $term" 4
402 .el .IP "on_refresh_begin \f(CW$term\fR" 4
403 .IX Item "on_refresh_begin $term"
404 Called just before the screen gets redrawn. Can be used for overlay
405 or similar effects by modify terminal contents in refresh_begin, and
406 restoring them in refresh_end. The built-in overlay and selection display
407 code is run after this hook, and takes precedence.
408 .ie n .IP "on_refresh_end $term" 4
409 .el .IP "on_refresh_end \f(CW$term\fR" 4
410 .IX Item "on_refresh_end $term"

415 Called whenever the user presses a key combination that has a
416 \&\f(CW\*(C`perl:string\*(C'\fR action bound to it (see description of the \fBkeysym\fR
417 resource in the @@RXVT_NAME@@(1) manpage).
