45 | the user extends selections (double-click). Right now, it tries to select |
|

|
|
227 | and calling C<< $term->scr_add_lines >> yourself. Please note that this |

|
234 | screen output (e.g. underline urls or other useless stuff). Only lines |
|
|
235 | that are being shown will be filtered, and, due to performance reasons, |
|

|
241 | Please note that, if you change the line, then the hook might get called |

612 | further work. The only exception is that you cannot wait on condition |

|
|
614 | cannot use blocking APIs, but the non-blocking variant should work. |

939 | =item $view_start = $term->view_start ([$newvalue]) |

|
|
942 | C<0>, which displays the normal terminal contents. Larger values scroll |
|
|
943 | this many lines into the scrollback buffer. |
|
|
944 | |
|
|
945 | =item $term->want_refresh |
|
|
946 | |
|
|
947 | Requests a screen refresh. At the next opportunity, rxvt-unicode will |
|
|
948 | compare the on-screen display with its stored representation. If they |
|
|
949 | differ, it redraws the differences. |
|
|
950 | |

951 | Used after changing terminal contents to display them. |
|
|
952 | |
|
|
953 | =item $text = $term->ROW_t ($row_number[, $new_text[, $start_col]]) |
|
|
954 | |
|
|
955 | Returns the text of the entire row with number C<$row_number>. Row C<0> |
|
|
956 | is the topmost terminal line, row C<< $term->$ncol-1 >> is the bottommost |
|
|
957 | terminal line. The scrollback buffer starts at line C<-1> and extends to |
|
|
958 | line C<< -$term->nsaved >>. Nothing will be returned if a nonexistent line |
|
|
959 | is requested. |
|
|
960 | |
|
|
961 | If C<$new_text> is specified, it will replace characters in the current |
|
|
962 | line, starting at column C<$start_col> (default C<0>), which is useful |
|
|
963 | to replace only parts of a line. The font index in the rendition will |
|
|
964 | automatically be updated. |
|
|
965 | |
|
|
966 | C<$text> is in a special encoding: tabs and wide characters that use more |
|
|
967 | than one cell when displayed are padded with urxvt::NOCHAR characters |
|
|
968 | (C<chr 65535>). Characters with combining characters and other characters |
|
|
969 | that do not fit into the normal tetx encoding will be replaced with |
|
|
970 | characters in the private use area. |
|
|
971 | |
|
|
972 | You have to obey this encoding when changing text. The advantage is |
|
|
973 | that C<substr> and similar functions work on screen cells and not on |
|
|
974 | characters. |
|
|
975 | |
|
|
976 | The methods C<< $term->special_encode >> and C<< $term->special_decode >> |
|
|
977 | can be used to convert normal strings into this encoding and vice versa. |
|
|
978 | |
|
|
979 | =item $rend = $term->ROW_r ($row_number[, $new_rend[, $start_col]]) |
|
|
980 | |
|
|
981 | Like C<< $term->ROW_t >>, but returns an arrayref with rendition |
|
|
982 | bitsets. Rendition bitsets contain information about colour, font, font |
|
|
983 | styles and similar information. See also C<< $term->ROW_t >>. |
|
|
984 | |
|
|
985 | When setting rendition, the font mask will be ignored. |
|
|
986 | |
|
|
987 | See the section on RENDITION, above. |
|
|
988 | |
|
|
989 | =item $length = $term->ROW_l ($row_number[, $new_length]) |
|
|
990 | |
|
|
991 | Returns the number of screen cells that are in use ("the line |
|
|
992 | length"). Unlike the urxvt core, this returns C<< $term->ncol >> if the |
|
|
993 | line is joined with the following one. |
|
|
994 | |
|
|
995 | =item $bool = $term->is_longer ($row_number) |
|
|
996 | |
|
|
997 | Returns true if the row is part of a multiple-row logical "line" (i.e. |
|
|
998 | joined with the following row), which means all characters are in use |
|
|
999 | and it is continued on the next row (and possibly a continuation of the |
|
|
1000 | previous row(s)). |
|
|
1001 | |
|
|
1002 | =item $line = $term->line ($row_number) |
|
|
1003 | |
|
|
1004 | Create and return a new C<urxvt::line> object that stores information |
|
|
1005 | about the logical line that row C<$row_number> is part of. It supports the |
|
|
1006 | following methods: |

1007 | |

1027 | |
|
|
1028 | =item $offset = $line->offset_of ($row, $col) |
