=head1 DESCRIPTION |
19 |
|
20 |
Everytime a terminal object gets created, scripts specified via the |
21 |
C<perl> resource are loaded and associated with it. |
22 |
|
23 |
Scripts are compiled in a 'use strict' and 'use utf8' environment, and |
24 |
thus must be encoded as UTF-8. |
25 |
|
26 |
Each script will only ever be loaded once, even in @@RXVT_NAME@@d, where |
27 |
scripts will be shared (But not enabled) for all terminals. |

This section describes the extensiosn delivered with this version. You can |
32 |
find them in F<@@RXVT_LIBDIR@@/urxvt/perl/>. |

56 |
Displays a very simple digital clock in the upper right corner of the |
57 |
window. Illustrates overwriting the refresh callbacks to create your own |
58 |
overlays or changes. |
59 |
|
60 |

=head2 General API Considerations |
67 |
|
68 |
All objects (such as terminals, time watchers etc.) are typical |
69 |
reference-to-hash objects. The hash can be used to store anything you |
70 |
like. All members starting with an underscore (such as C<_ptr> or |
71 |
C<_hook>) are reserved for internal uses and must not be accessed or |
72 |
modified). |
73 |
|
74 |
When objects are destroyed on the C++ side, the perl object hashes are |
75 |
emptied, so its best to store related objects such as time watchers and |
76 |
the like inside the terminal object so they get destroyed as soon as the |
77 |
terminal is destroyed. |
78 |
|
79 |
=head2 Hooks |
80 |
|
81 |
The following subroutines can be declared in loaded scripts, and will be called |
82 |
whenever the relevant event happens. |
83 |
|
84 |
All of them must return a boolean value. If it is true, then the event |
85 |
counts as being I<consumed>, and the invocation of other hooks is skipped, |
86 |
and the relevant action might not be carried out by the C++ code. |
87 |
|
88 |
When in doubt, return a false value (preferably C<()>). |
89 |
|
90 |
=over 4 |
91 |
|
92 |
=item on_init $term |
93 |
|
94 |
Called after a new terminal object has been initialized, but before |
95 |
windows are created or the command gets run. |
96 |
|
97 |
=item on_reset $term |
98 |
|
99 |
Called after the screen is "reset" for any reason, such as resizing or |
100 |
control sequences. Here is where you can react on changes to size-related |
101 |
variables. |
102 |
|
103 |
=item on_start $term |
104 |
|
105 |
Called at the very end of initialisation of a new terminal, just before |
106 |
returning to the mainloop. |
107 |
|
108 |
=item on_sel_make $term, $eventtime |
109 |
|
110 |
Called whenever a selection has been made by the user, but before the |
111 |
selection text is copied, so changes to the beginning, end or type of the |
112 |
selection will be honored. |
113 |
|
114 |
Returning a true value aborts selection making by urxvt, in which case you |
115 |
have to make a selection yourself by calling C<< $term->selection_grab >>. |
116 |
|
117 |
=item on_sel_grab $term, $eventtime |
118 |
|
119 |
Called whenever a selection has been copied, but before the selection is |
120 |
requested from the server. The selection text can be queried and changed |
121 |
by calling C<< $term->selection >>. |
122 |
|
123 |
Returning a true value aborts selection grabbing. It will still be hilighted. |
124 |
|
125 |
=item on_focus_in $term |
126 |
|
127 |
Called whenever the window gets the keyboard focus, before urxvt does |
128 |
focus in processing. |
129 |
|
130 |
=item on_focus_out $term |
131 |
|
132 |
Called wheneever the window loses keyboard focus, before urxvt does focus |
133 |
out processing. |
134 |
|
135 |
=item on_view_change $term, $offset |
136 |
|
137 |
Called whenever the view offset changes, i..e the user or program |
138 |
scrolls. Offset C<0> means display the normal terminal, positive values |
139 |
show this many lines of scrollback. |
140 |
|
141 |
=item on_scroll_back $term, $lines, $saved |
142 |
|
143 |
Called whenever lines scroll out of the terminal area into the scrollback |
144 |
buffer. C<$lines> is the number of lines scrolled out and may be larger |
145 |
than the scroll back buffer or the terminal. |
146 |
|
147 |
It is called before lines are scrolled out (so rows 0 .. min ($lines - 1, |
148 |
$nrow - 1) represent the lines to be scrolled out). C<$saved> is the total |
149 |
number of lines that will be in the scrollback buffer. |
150 |
|
151 |
=item on_tty_activity $term *NYI* |
152 |
|
153 |
Called whenever the program(s) running in the urxvt window send output. |
154 |
|
155 |
=item on_refresh_begin $term |
156 |
|
157 |
Called just before the screen gets redrawn. Can be used for overlay |
158 |
or similar effects by modify terminal contents in refresh_begin, and |
159 |
restoring them in refresh_end. The built-in overlay and selection display |
160 |
code is run after this hook, and takes precedence. |
161 |
|
162 |
=item on_refresh_end $term |
163 |
|
164 |
Called just after the screen gets redrawn. See C<on_refresh_begin>. |
165 |
|
166 |
=item on_keyboard_command $term, $string |
167 |
|
168 |
Called whenever the user presses a key combination that has a |
169 |
C<perl:string> action bound to it (see description of the B<keysym> |
170 |
resource in the @@RXVT_NAME@@(1) manpage). |

=item urxvt::fatal $errormessage |
179 |
|
180 |
Fatally aborts execution with the given error message. Avoid at all |
181 |
costs! The only time this is acceptable is when the terminal process |
182 |
starts up. |
183 |
|
184 |
=item urxvt::warn $string |
185 |
|
186 |
Calls C<rxvt_warn> with the given string which should not include a |
187 |
newline. The module also overwrites the C<warn> builtin with a function |
188 |
that calls this function. |
189 |
|
190 |
Using this function has the advantage that its output ends up in the |

correct place, e.g. on stderr of the connecting urxvtc client. |
192 |

=item $value = $term->resource ($name[, $newval]) |
317 |
|
318 |
Returns the current resource value associated with a given name and |
319 |
optionally sets a new value. Setting values is most useful in the C<init> |
320 |
hook. Unset resources are returned and accepted as C<undef>. |
321 |
|
322 |
The new value must be properly encoded to a suitable character encoding |
323 |
before passing it to this method. Similarly, the returned value may need |
324 |
to be converted from the used encoding to text. |
325 |
|
326 |
Resource names are as defined in F<src/rsinc.h>. Colours can be specified |
327 |
as resource names of the form C<< color+<index> >>, e.g. C<color+5>. (will |
328 |
likely change). |

Please note that resource strings will currently only be freed when the |

411 |
|
412 |
=item $term->scr_overlay_set ($x, $y, $text) |

=item $cellwidth = $term->strwidth $string |
417 |
|

accounts for wide and combining characters. |
420 |
|
421 |
=item $octets = $term->locale_encode $string |
422 |
|
423 |
Convert the given text string into the corresponding locale encoding. |
424 |
|
425 |
=item $string = $term->locale_decode $octets |
426 |
|
427 |
Convert the given locale-encoded octets into a perl string. |
428 |
|
429 |
=item $term->tt_write ($octets) |
430 |
|
431 |
Write the octets given in C<$data> to the tty (i.e. as program input). To |
432 |
pass characters instead of octets, you should convert your strings first |
433 |
to the locale-specific encoding using C<< $term->locale_encode >>. |

=item $nrow = $term->nrow |
436 |
|

438 |
|
439 |
Return the number of rows/columns of the terminal window (i.e. as |
440 |
specified by C<-geometry>, excluding any scrollback). |
441 |
|
442 |
=item $nsaved = $term->nsaved |
443 |
|
444 |
Returns the number of lines in the scrollback buffer. |
445 |
|
446 |
=item $view_start = $term->view_start ([$newvalue]) |
447 |
|
448 |
Returns the negative row number of the topmost line. Minimum value is |
449 |
C<0>, which displays the normal terminal contents. Larger values scroll |
450 |
this many lines into the scrollback buffer. |
451 |
|
452 |
=item $term->want_refresh |
453 |
|
454 |
Requests a screen refresh. At the next opportunity, rxvt-unicode will |
455 |
compare the on-screen display with its stored representation. If they |
456 |
differ, it redraws the differences. |
457 |
|
458 |
Used after changing terminal contents to display them. |
459 |
|
460 |
=item $text = $term->ROW_t ($row_number[, $new_text[, $start_col]]) |
461 |
|
462 |
Returns the text of the entire row with number C<$row_number>. Row C<0> |
463 |
is the topmost terminal line, row C<< $term->$ncol-1 >> is the bottommost |
464 |
terminal line. The scrollback buffer starts at line C<-1> and extends to |
465 |
line C<< -$term->nsaved >>. |
466 |
|
467 |
If C<$new_text> is specified, it will replace characters in the current |
468 |
line, starting at column C<$start_col> (default C<0>), which is useful |
469 |
to replace only parts of a line. The font iindex in the rendition will |
470 |
automatically be updated. |
471 |
|
472 |
C<$text> is in a special encoding: tabs and wide characters that use more |
473 |
than one cell when displayed are padded with urxvt::NOCHAR characters |
474 |
(C<chr 65535>). Characters with combining characters and other characters |
475 |
that do not fit into the normal tetx encoding will be replaced with |
476 |
characters in the private use area. |

You have to obey this encoding when changing text. The advantage is |
479 |
that C<substr> and similar functions work on screen cells and not on |
480 |
characters. |
481 |
|
482 |
The methods C<< $term->special_encode >> and C<< $term->special_decode >> |
483 |
can be used to convert normal strings into this encoding and vice versa. |
484 |
|
485 |
=item $rend = $term->ROW_r ($row_number[, $new_rend[, $start_col]]) |
486 |
|
487 |
Like C<< $term->ROW_t >>, but returns an arrayref with rendition |
488 |
bitsets. Rendition bitsets contain information about colour, font, font |
489 |
styles and similar information. See also C<< $term->ROW_t >>. |
490 |
|
491 |
When setting rendition, the font mask will be ignored. |
492 |
|
493 |
See the section on RENDITION, below. |
494 |
|
495 |
=item $length = $term->ROW_l ($row_number[, $new_length]) |
496 |
|
497 |
Returns the number of screen cells that are in use ("the line length"). If |
498 |
it is C<-1>, then the line is part of a multiple-row logical "line", which |
499 |
means all characters are in use and it is continued on the next row. |
500 |
|
501 |
=item $text = $term->special_encode $string |
502 |
|
503 |
Converts a perl string into the special encoding used by rxvt-unicode, |
504 |
where one character corresponds to one screen cell. See |
505 |
C<< $term->ROW_t >> for details. |
506 |
|
507 |
=item $string = $term->special_decode $text |
508 |
|
509 |
Converts rxvt-unicodes text reprsentation into a perl string. See |
510 |
C<< $term->ROW_t >> for details. |

=head2 RENDITION |
515 |
|
516 |
Rendition bitsets contain information about colour, font, font styles and |
517 |
similar information for each screen cell. |
518 |
|
519 |
The following "macros" deal with changes in rendition sets. You should |
520 |
never just create a bitset, you should always modify an existing one, |
521 |
as they contain important information required for correct operation of |
522 |
rxvt-unicode. |

=head2 The C<urxvt::timer> Class |
536 |
|
537 |
This class implements timer watchers/events. Time is represented as a |
538 |
fractional number of seconds since the epoch. Example: |
539 |
|
540 |
# create a digital clock display in upper right corner |
541 |
$term->{timer} = urxvt::timer |
542 |
->new |
543 |
->start (urxvt::NOW) |
544 |
->cb (sub { |
545 |
my ($timer) = @_; |
546 |
my $time = $timer->at; |
547 |
$timer->start ($time + 1); |
548 |
$self->scr_overlay (-1, 0, |
549 |
POSIX::strftime "%H:%M:%S", localtime $time); |
550 |
}); |
551 |
|
552 |
=over 4 |
553 |
|
554 |
=item $timer = new urxvt::timer |
555 |
|
556 |
Create a new timer object in stopped state. |
557 |
|
558 |
=item $timer = $timer->cb (sub { my ($timer) = @_; ... }) |
559 |
|
560 |
Set the callback to be called when the timer triggers. |
561 |
|
562 |
=item $tstamp = $timer->at |
563 |
|
564 |
Return the time this watcher will fire next. |
565 |
|
566 |
=item $timer = $timer->set ($tstamp) |
567 |
|
568 |
Set the time the event is generated to $tstamp. |
569 |
|
570 |
=item $timer = $timer->start |
571 |
|
572 |
Start the timer. |
573 |
|
574 |
=item $timer = $timer->start ($tstamp) |
575 |
|
576 |
Set the event trigger time to C<$tstamp> and start the timer. |
577 |
|
578 |
=item $timer = $timer->stop |
579 |
|
580 |
Stop the timer. |

=head2 The C<urxvt::iow> Class |
585 |
|
586 |
This class implements io watchers/events. Example: |
587 |
|
588 |
$term->{socket} = ... |
589 |
$term->{iow} = urxvt::iow |
590 |
->new |
591 |
->fd (fileno $term->{socket}) |
592 |
->events (1) # wait for read data |
593 |
->start |
594 |
->cb (sub { |
595 |
my ($iow, $revents) = @_; |
596 |
# $revents must be 1 here, no need to check |
597 |
sysread $term->{socket}, my $buf, 8192 |
598 |
or end-of-file; |
599 |
}); |
