177 (More) intelligent selection. This extension tries to be more intelligent
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.

223 A not very useful example of filtering all text output to the terminal,
224 by replacing all line-drawing characters (U+2500 .. U+259F) by a
225 similar-looking ascii character.
226 .IP "example-refresh-hooks" 4

233 .Sh "General \s-1API\s0 Considerations"
234 .IX Subsection "General API Considerations"
235 All objects (such as terminals, time watchers etc.) are typical
236 reference-to-hash objects. The hash can be used to store anything you
237 like. All members starting with an underscore (such as \f(CW\*(C`_ptr\*(C'\fR or
238 \&\f(CW\*(C`_hook\*(C'\fR) are reserved for internal uses and \fB\s-1MUST\s0 \s-1NOT\s0\fR be accessed or
239 modified).
240 .PP
241 When objects are destroyed on the \*(C+ side, the perl object hashes are
242 emptied, so its best to store related objects such as time watchers and
243 the like inside the terminal object so they get destroyed as soon as the
244 terminal is destroyed.
245 .PP
246 Argument names also often indicate the type of a parameter. Here are some
247 hints on what they mean:
248 .IP "$text" 4
249 .IX Item "$text"
250 Rxvt-unicodes special way of encoding text, where one \*(L"unicode\*(R" character
251 always represents one screen cell. See ROW_t for a discussion of this format.
252 .IP "$string" 4
253 .IX Item "$string"
254 A perl text string, with an emphasis on \fItext\fR. It can store all unicode
255 characters and is to be distinguished with text encoded in a specific
256 encoding (often locale\-specific) and binary data.
257 .IP "$octets" 4
258 .IX Item "$octets"
259 Either binary data or \- more common \- a text string encoded in a
260 locale-specific way.
261 .Sh "Extension Objects"
262 .IX Subsection "Extension Objects"
263 Very perl extension is a perl class. A separate perl object is created
264 for each terminal and each extension and passed as the first parameter to
265 hooks. So extensions can use their \f(CW$self\fR object without having to think
266 about other extensions, with the exception of methods and members that
267 begin with an underscore character \f(CW\*(C`_\*(C'\fR: these are reserved for internal
268 use.
269 .PP
270 Although it isn't a \f(CW\*(C`urxvt::term\*(C'\fR object, you can call all methods of the
271 \&\f(CW\*(C`urxvt::term\*(C'\fR class on this object.
272 .PP
273 It has the following methods and data members:
274 .ie n .IP "$urxvt_term = $self\->{term}" 4
275 .el .IP "$urxvt_term = \f(CW$self\fR\->{term}" 4
276 .IX Item "$urxvt_term = $self->{term}"
277 Returns the \f(CW\*(C`urxvt::term\*(C'\fR object associated with this instance of the
278 extension. This member \fImust not\fR be changed in any way.
279 .ie n .IP "$self\->enable ($hook_name => $cb\fR, [$hook_name => \f(CW$cb..])" 4
280 .el .IP "$self\->enable ($hook_name => \f(CW$cb\fR, [$hook_name => \f(CW$cb\fR..])" 4
281 .IX Item "$self->enable ($hook_name => $cb, [$hook_name => $cb..])"
282 Dynamically enable the given hooks (named without the \f(CW\*(C`on_\*(C'\fR prefix) for
283 this extension, replacing any previous hook. This is useful when you want
284 to overwrite time-critical hooks only temporarily.
285 .ie n .IP "$self\->disable ($hook_name[, $hook_name..])" 4
286 .el .IP "$self\->disable ($hook_name[, \f(CW$hook_name\fR..])" 4
287 .IX Item "$self->disable ($hook_name[, $hook_name..])"
288 Dynamically disable the given hooks.
289 .Sh "Hooks"
290 .IX Subsection "Hooks"
291 The following subroutines can be declared in extension files, and will be
292 called whenever the relevant event happens.
293 .PP
294 The first argument passed to them is an extension oject as described in
295 the in the \f(CW\*(C`Extension Objects\*(C'\fR section.
296 .PP
297 \&\fBAll\fR of these hooks must return a boolean value. If it is true, then the
298 event counts as being \fIconsumed\fR, and the invocation of other hooks is
299 skipped, and the relevant action might not be carried out by the \*(C+ code.
300 .PP
301 \&\fIWhen in doubt, return a false value (preferably \f(CI\*(C`()\*(C'\fI).\fR
302 .ie n .IP "on_init $term" 4
303 .el .IP "on_init \f(CW$term\fR" 4
304 .IX Item "on_init $term"
305 Called after a new terminal object has been initialized, but before
306 windows are created or the command gets run. Most methods are unsafe to
307 call or deliver senseless data, as terminal size and other characteristics
308 have not yet been determined. You can safely query and change resources,
309 though.
310 .ie n .IP "on_reset $term" 4
311 .el .IP "on_reset \f(CW$term\fR" 4
312 .IX Item "on_reset $term"
313 Called after the screen is \*(L"reset\*(R" for any reason, such as resizing or
314 control sequences. Here is where you can react on changes to size-related
315 variables.
316 .ie n .IP "on_start $term" 4
317 .el .IP "on_start \f(CW$term\fR" 4
318 .IX Item "on_start $term"
319 Called at the very end of initialisation of a new terminal, just before
320 returning to the mainloop.
321 .ie n .IP "on_sel_make $term\fR, \f(CW$eventtime" 4
322 .el .IP "on_sel_make \f(CW$term\fR, \f(CW$eventtime\fR" 4
323 .IX Item "on_sel_make $term, $eventtime"
324 Called whenever a selection has been made by the user, but before the
325 selection text is copied, so changes to the beginning, end or type of the
326 selection will be honored.
327 .Sp
328 Returning a true value aborts selection making by urxvt, in which case you
329 have to make a selection yourself by calling \f(CW\*(C`$term\->selection_grab\*(C'\fR.
330 .ie n .IP "on_sel_grab $term\fR, \f(CW$eventtime" 4
331 .el .IP "on_sel_grab \f(CW$term\fR, \f(CW$eventtime\fR" 4
332 .IX Item "on_sel_grab $term, $eventtime"
333 Called whenever a selection has been copied, but before the selection is
334 requested from the server. The selection text can be queried and changed
335 by calling \f(CW\*(C`$term\->selection\*(C'\fR.
336 .Sp
337 Returning a true value aborts selection grabbing. It will still be hilighted.
338 .ie n .IP "on_sel_extend $term" 4
339 .el .IP "on_sel_extend \f(CW$term\fR" 4
340 .IX Item "on_sel_extend $term"
341 Called whenever the user tries to extend the selection (e.g. with a double
342 click) and is either supposed to return false (normal operation), or
343 should extend the selection itelf and return true to suppress the built-in
344 processing.
345 .Sp
346 See the \fIselection\fR example extension.
347 .ie n .IP "on_view_change $term\fR, \f(CW$offset" 4
348 .el .IP "on_view_change \f(CW$term\fR, \f(CW$offset\fR" 4
349 .IX Item "on_view_change $term, $offset"
350 Called whenever the view offset changes, i..e the user or program
351 scrolls. Offset \f(CW0\fR means display the normal terminal, positive values
352 show this many lines of scrollback.
353 .ie n .IP "on_scroll_back $term\fR, \f(CW$lines\fR, \f(CW$saved" 4
354 .el .IP "on_scroll_back \f(CW$term\fR, \f(CW$lines\fR, \f(CW$saved\fR" 4
355 .IX Item "on_scroll_back $term, $lines, $saved"
356 Called whenever lines scroll out of the terminal area into the scrollback
357 buffer. \f(CW$lines\fR is the number of lines scrolled out and may be larger
358 than the scroll back buffer or the terminal.
359 .Sp
360 It is called before lines are scrolled out (so rows 0 .. min ($lines \- 1,
361 \&\f(CW$nrow\fR \- 1) represent the lines to be scrolled out). \f(CW$saved\fR is the total
362 number of lines that will be in the scrollback buffer.
363 .ie n .IP "on_osc_seq $term\fR, \f(CW$string" 4
364 .el .IP "on_osc_seq \f(CW$term\fR, \f(CW$string\fR" 4
365 .IX Item "on_osc_seq $term, $string"
366 Called whenever the \fB\s-1ESC\s0 ] 777 ; string \s-1ST\s0\fR command sequence (\s-1OSC\s0 =
367 operating system command) is processed. Cursor position and other state
368 information is up-to-date when this happens. For interoperability, the
369 string should start with the extension name and a colon, to distinguish
370 it from commands for other extensions, and this might be enforced in the
371 future.
372 .Sp
373 Be careful not ever to trust (in a security sense) the data you receive,
374 as its source can not easily be controleld (e\-mail content, messages from
375 other users on the same system etc.).
376 .ie n .IP "on_add_lines $term\fR, \f(CW$string" 4
377 .el .IP "on_add_lines \f(CW$term\fR, \f(CW$string\fR" 4
378 .IX Item "on_add_lines $term, $string"
379 Called whenever text is about to be output, with the text as argument. You
380 can filter/change and output the text yourself by returning a true value
381 and calling \f(CW\*(C`$term\->scr_add_lines\*(C'\fR yourself. Please note that this
382 might be very slow, however, as your hook is called for \fBall\fR text being
383 output.
384 .ie n .IP "on_tt_write $term\fR, \f(CW$octets" 4
385 .el .IP "on_tt_write \f(CW$term\fR, \f(CW$octets\fR" 4
386 .IX Item "on_tt_write $term, $octets"
387 Called whenever some data is written to the tty/pty and can be used to
388 suppress or filter tty input.
389 .ie n .IP "on_line_update $term\fR, \f(CW$row" 4
390 .el .IP "on_line_update \f(CW$term\fR, \f(CW$row\fR" 4
391 .IX Item "on_line_update $term, $row"
392 Called whenever a line was updated or changed. Can be used to filter
393 screen output (e.g. underline urls or other useless stuff). Only lines
394 that are being shown will be filtered, and, due to performance reasons,
395 not always immediately.
396 .Sp
397 The row number is always the topmost row of the line if the line spans
398 multiple rows.
399 .Sp
400 Please note that, if you change the line, then the hook might get called
401 later with the already-modified line (e.g. if unrelated parts change), so
402 you cannot just toggle rendition bits, but only set them.
403 .ie n .IP "on_refresh_begin $term" 4
404 .el .IP "on_refresh_begin \f(CW$term\fR" 4
405 .IX Item "on_refresh_begin $term"
406 Called just before the screen gets redrawn. Can be used for overlay
407 or similar effects by modify terminal contents in refresh_begin, and
408 restoring them in refresh_end. The built-in overlay and selection display
409 code is run after this hook, and takes precedence.
410 .ie n .IP "on_refresh_end $term" 4
411 .el .IP "on_refresh_end \f(CW$term\fR" 4
412 .IX Item "on_refresh_end $term"
413 Called just after the screen gets redrawn. See \f(CW\*(C`on_refresh_begin\*(C'\fR.
414 .ie n .IP "on_keyboard_command $term\fR, \f(CW$string" 4
415 .el .IP "on_keyboard_command \f(CW$term\fR, \f(CW$string\fR" 4
