|
|
205 | never just create a bitset, you should always modify an existing one, |
|
|
206 | as they contain important information required for correct operation of |

|
|
494 | |
|
|
495 | =item $ncol = $term->ncol |
|
|
496 | |
|
|
497 | Return the number of rows/columns of the terminal window (i.e. as |
|
|
498 | specified by C<-geometry>, excluding any scrollback). |
|
|
499 | |
|
|
500 | =item $nsaved = $term->nsaved |
|
|
501 | |
|
|
502 | Returns the number of lines in the scrollback buffer. |
|
|
503 | |
|
|
504 | =item $view_start = $term->view_start ([$newvalue]) |
|
|
505 | |
|
|
506 | Returns the negative row number of the topmost line. Minimum value is |
|
|
507 | C<0>, which displays the normal terminal contents. Larger values scroll |
|
|
508 | this many lines into the scrollback buffer. |
|
|
509 | |
|
|
510 | =item $term->want_refresh |
|
|
511 | |
|
|
512 | Requests a screen refresh. At the next opportunity, rxvt-unicode will |
|
|
513 | compare the on-screen display with its stored representation. If they |
|
|
514 | differ, it redraws the differences. |
|
|
515 | |
|
|
516 | Used after changing terminal contents to display them. |
|
|
517 | |
|
|
518 | =item $text = $term->ROW_t ($row_number[, $new_text[, $start_col]]) |
|
|
519 | |
|
|
520 | Returns the text of the entire row with number C<$row_number>. Row C<0> |
|
|
521 | is the topmost terminal line, row C<< $term->$ncol-1 >> is the bottommost |
|
|
522 | terminal line. The scrollback buffer starts at line C<-1> and extends to |
|
|
523 | line C<< -$term->nsaved >>. |
|
|
524 | |
|
|
525 | If C<$new_text> is specified, it will replace characters in the current |
|
|
526 | line, starting at column C<$start_col> (default C<0>), which is useful |
|
|
527 | to replace only parts of a line. The font index in the rendition will |
|
|
528 | automatically be updated. |
|
|
529 | |
|
|
530 | C<$text> is in a special encoding: tabs and wide characters that use more |
|
|
531 | than one cell when displayed are padded with urxvt::NOCHAR characters |
|
|
532 | (C<chr 65535>). Characters with combining characters and other characters |
|
|
533 | that do not fit into the normal tetx encoding will be replaced with |
|
|
534 | characters in the private use area. |
|
|
535 | |
|
|
536 | You have to obey this encoding when changing text. The advantage is |
|
|
537 | that C<substr> and similar functions work on screen cells and not on |
|
|
538 | characters. |
|
|
539 | |
|
|
540 | The methods C<< $term->special_encode >> and C<< $term->special_decode >> |
|
|
541 | can be used to convert normal strings into this encoding and vice versa. |
|
|
542 | |
|
|
543 | =item $rend = $term->ROW_r ($row_number[, $new_rend[, $start_col]]) |
|
|
544 | |
|
|
545 | Like C<< $term->ROW_t >>, but returns an arrayref with rendition |
|
|
546 | bitsets. Rendition bitsets contain information about colour, font, font |
|
|
547 | styles and similar information. See also C<< $term->ROW_t >>. |
|
|
548 | |
|
|
549 | When setting rendition, the font mask will be ignored. |
|
|
550 | |
|
|
551 | See the section on RENDITION, above. |
|
|
552 | |
|
|
553 | =item $length = $term->ROW_l ($row_number[, $new_length]) |
|
|
554 | |
|
|
555 | Returns the number of screen cells that are in use ("the line length"). If |
|
|
556 | it is C<-1>, then the line is part of a multiple-row logical "line", which |
|
|
557 | means all characters are in use and it is continued on the next row. |
|
|
558 | |
|
|
559 | =item $text = $term->special_encode $string |
|
|
560 | |
|
|
561 | Converts a perl string into the special encoding used by rxvt-unicode, |
|
|
562 | where one character corresponds to one screen cell. See |
|
|
563 | C<< $term->ROW_t >> for details. |
|
|
564 | |
|
|
565 | =item $string = $term->special_decode $text |
|
|
566 | |
|
|
567 | Converts rxvt-unicodes text reprsentation into a perl string. See |
|
|
568 | C<< $term->ROW_t >> for details. |
