77 | A not very useful example of filtering all text output to the terminal, by |

78 | underlining all urls that matches a certain regex (i.e. some urls :). It |
|
|
79 | is not very useful because urls that are output in multiple steps (e.g. |

104 | Rxvt-unicodes special way of encoding text, where one "unicode" character |

105 | always represents one screen cell. See L<row_t> for a discussion of this format. |
|
|
106 | |
|
|
107 | =item $string |
|
|
108 | |
|
|
109 | A perl text string, with an emphasis on I<text>. It can store all unicode |
|
|
110 | characters and is to be distinguished with text encoded in a specific |
|
|
111 | encoding (often locale-specific) and binary data. |
|
|
112 | |

224 | =item on_add_lines $term, $string |
|
|
225 | |
|
|
226 | Called whenever text is about to be output, with the text as argument. You |
|
|
227 | can filter/change and output the text yourself by returning a true value |
|
|
228 | and calling C<< $term->scr_add_lines >> yourself. Please note that this |
|
|
229 | might be very slow, however, as your hook is called for B<all> text being |
|
|
230 | output. |

|
|
232 | =item on_line_update $term, $row |
|
|
233 | |
|
|
234 | Called whenever a line was updated or changed. Can be used to filter |
|
|
235 | screen output (e.g. underline urls or other useless stuff). Only lines |
|
|
236 | that are being shown will be filtered, and, due to performance reasons, |
|
|
237 | not always immediately. |
|
|
238 | |
|
|
239 | The row number is always the topmost row of the line if the line spans |
|
|
240 | multiple rows. |
|
|
241 | |
|
|
242 | Please note that, if you change the line, then the hook might get called |
|
|
243 | later with the already-modified line (e.g. if unrelated parts change), so |
|
|
244 | you cannot just toggle rendition bits, but only set them. |
