179     urls and complete shell-quoted arguments, which is very convenient, too,

206     A not very useful example of filtering all text output to the terminal,
207     by replacing all line-drawing characters (U+2500 .. U+259F) by a
208     similar-looking ascii character.
209 root 1.8 .IP "example-refresh-hooks" 4
210     .IX Item "example-refresh-hooks"
211 root 1.6 Displays a very simple digital clock in the upper right corner of the
212     window. Illustrates overwriting the refresh callbacks to create your own
213     overlays or changes.
214 root 1.3 .Sh "General \s-1API\s0 Considerations"
215     .IX Subsection "General API Considerations"
216     All objects (such as terminals, time watchers etc.) are typical
217     reference-to-hash objects. The hash can be used to store anything you
218     like. All members starting with an underscore (such as \f(CW\*(C`_ptr\*(C'\fR or
219 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
220 root 1.3 modified).
221     .PP
222     When objects are destroyed on the \*(C+ side, the perl object hashes are
223     emptied, so its best to store related objects such as time watchers and
224     the like inside the terminal object so they get destroyed as soon as the
225     terminal is destroyed.
226 root 1.14 .PP
227     Argument names also often indicate the type of a parameter. Here are some
228     hints on what they mean:
229     .IP "$text" 4
230     .IX Item "$text"
231     Rxvt-unicodes special way of encoding text, where one \*(L"unicode\*(R" character
232     always represents one screen cell. See row_t for a discussion of this format.
233     .IP "$string" 4
234     .IX Item "$string"
235     A perl text string, with an emphasis on \fItext\fR. It can store all unicode
236     characters and is to be distinguished with text encoded in a specific
237     encoding (often locale\-specific) and binary data.
238     .IP "$octets" 4
239     .IX Item "$octets"
240     Either binary data or \- more common \- a text string encoded in a
241     locale-specific way.
242 root 1.1 .Sh "Hooks"
243     .IX Subsection "Hooks"
244 root 1.14 The following subroutines can be declared in extension files, and will be
245 root 1.9 called whenever the relevant event happens.
246     .PP
247     The first argument passed to them is an object private to each terminal
248 root 1.15 and extension package. You can call all \f(CW\*(C`urxvt::term\*(C'\fR methods on it, but
249 root 1.9 its not a real \f(CW\*(C`urxvt::term\*(C'\fR object. Instead, the real \f(CW\*(C`urxvt::term\*(C'\fR
250     object that is shared between all packages is stored in the \f(CW\*(C`term\*(C'\fR
251 root 1.15 member. It is, however, blessed intot he package of the extension script,
252     so for all practical purposes you can treat an extension script as a class.
253 root 1.1 .PP
254     All of them must return a boolean value. If it is true, then the event
255     counts as being \fIconsumed\fR, and the invocation of other hooks is skipped,
256     and the relevant action might not be carried out by the \*(C+ code.
257     .PP
258     When in doubt, return a false value (preferably \f(CW\*(C`()\*(C'\fR).
259     .ie n .IP "on_init $term" 4
260     .el .IP "on_init \f(CW$term\fR" 4
261     .IX Item "on_init $term"
262     Called after a new terminal object has been initialized, but before
263 root 1.14 windows are created or the command gets run. Most methods are unsafe to
264     call or deliver senseless data, as terminal size and other characteristics
265     have not yet been determined. You can safely query and change resources,
266     though.
267 root 1.1 .ie n .IP "on_reset $term" 4
268     .el .IP "on_reset \f(CW$term\fR" 4
269     .IX Item "on_reset $term"
270     Called after the screen is \*(L"reset\*(R" for any reason, such as resizing or
271     control sequences. Here is where you can react on changes to size-related
272     variables.
273     .ie n .IP "on_start $term" 4
274     .el .IP "on_start \f(CW$term\fR" 4
275     .IX Item "on_start $term"
276     Called at the very end of initialisation of a new terminal, just before
277     returning to the mainloop.
278     .ie n .IP "on_sel_make $term\fR, \f(CW$eventtime" 4
279     .el .IP "on_sel_make \f(CW$term\fR, \f(CW$eventtime\fR" 4
280     .IX Item "on_sel_make $term, $eventtime"
281     Called whenever a selection has been made by the user, but before the
282     selection text is copied, so changes to the beginning, end or type of the
283     selection will be honored.
284     .Sp
285     Returning a true value aborts selection making by urxvt, in which case you
286     have to make a selection yourself by calling \f(CW\*(C`$term\->selection_grab\*(C'\fR.
287     .ie n .IP "on_sel_grab $term\fR, \f(CW$eventtime" 4
288     .el .IP "on_sel_grab \f(CW$term\fR, \f(CW$eventtime\fR" 4
289     .IX Item "on_sel_grab $term, $eventtime"
290     Called whenever a selection has been copied, but before the selection is
291     requested from the server. The selection text can be queried and changed
292     by calling \f(CW\*(C`$term\->selection\*(C'\fR.
293     .Sp
294     Returning a true value aborts selection grabbing. It will still be hilighted.
295 root 1.9 .ie n .IP "on_sel_extend $term" 4
296     .el .IP "on_sel_extend \f(CW$term\fR" 4
297     .IX Item "on_sel_extend $term"
298     Called whenever the user tries to extend the selection (e.g. with a double
299     click) and is either supposed to return false (normal operation), or
300     should extend the selection itelf and return true to suppress the built-in
301     processing.
302     .Sp
303     See the \fIselection\fR example extension.
304 root 1.1 .ie n .IP "on_view_change $term\fR, \f(CW$offset" 4
305     .el .IP "on_view_change \f(CW$term\fR, \f(CW$offset\fR" 4
306     .IX Item "on_view_change $term, $offset"
307     Called whenever the view offset changes, i..e the user or program
308     scrolls. Offset \f(CW0\fR means display the normal terminal, positive values
309     show this many lines of scrollback.
310     .ie n .IP "on_scroll_back $term\fR, \f(CW$lines\fR, \f(CW$saved" 4
311     .el .IP "on_scroll_back \f(CW$term\fR, \f(CW$lines\fR, \f(CW$saved\fR" 4
312     .IX Item "on_scroll_back $term, $lines, $saved"
313     Called whenever lines scroll out of the terminal area into the scrollback
314     buffer. \f(CW$lines\fR is the number of lines scrolled out and may be larger
315     than the scroll back buffer or the terminal.
316     .Sp
317     It is called before lines are scrolled out (so rows 0 .. min ($lines \- 1,
318     \&\f(CW$nrow\fR \- 1) represent the lines to be scrolled out). \f(CW$saved\fR is the total
319     number of lines that will be in the scrollback buffer.
320     .ie n .IP "on_tty_activity $term *NYI*" 4
321     .el .IP "on_tty_activity \f(CW$term\fR *NYI*" 4
322     .IX Item "on_tty_activity $term *NYI*"
323     Called whenever the program(s) running in the urxvt window send output.
324 root 1.11 .ie n .IP "on_osc_seq $term\fR, \f(CW$string" 4
325     .el .IP "on_osc_seq \f(CW$term\fR, \f(CW$string\fR" 4
326     .IX Item "on_osc_seq $term, $string"
327     Called whenever the \fB\s-1ESC\s0 ] 777 ; string \s-1ST\s0\fR command sequence (\s-1OSC\s0 =
328     operating system command) is processed. Cursor position and other state
329     information is up-to-date when this happens. For interoperability, the
330     string should start with the extension name and a colon, to distinguish
331     it from commands for other extensions, and this might be enforced in the
332     future.
333     .Sp
334     Be careful not ever to trust (in a security sense) the data you receive,
335     as its source can not easily be controleld (e\-mail content, messages from
336     other users on the same system etc.).
337 root 1.14 .ie n .IP "on_add_lines $term\fR, \f(CW$string" 4
338     .el .IP "on_add_lines \f(CW$term\fR, \f(CW$string\fR" 4
339     .IX Item "on_add_lines $term, $string"
340     Called whenever text is about to be output, with the text as argument. You
341     can filter/change and output the text yourself by returning a true value
342     and calling \f(CW\*(C`$term\->scr_add_lines\*(C'\fR yourself. Please note that this
343     might be very slow, however, as your hook is called for \fBall\fR text being
344     output.
345     .ie n .IP "on_line_update $term\fR, \f(CW$row" 4
346     .el .IP "on_line_update \f(CW$term\fR, \f(CW$row\fR" 4
347     .IX Item "on_line_update $term, $row"
348     Called whenever a line was updated or changed. Can be used to filter
349     screen output (e.g. underline urls or other useless stuff). Only lines
350     that are being shown will be filtered, and, due to performance reasons,
351     not always immediately.
352     .Sp
353     The row number is always the topmost row of the line if the line spans
354     multiple rows.
355     .Sp
356     Please note that, if you change the line, then the hook might get called
357     later with the already-modified line (e.g. if unrelated parts change), so
358     you cannot just toggle rendition bits, but only set them.

360     .el .IP "on_refresh_begin \f(CW$term\fR" 4
361     .IX Item "on_refresh_begin $term"
362     Called just before the screen gets redrawn. Can be used for overlay
363     or similar effects by modify terminal contents in refresh_begin, and
364     restoring them in refresh_end. The built-in overlay and selection display
365     code is run after this hook, and takes precedence.
