|
|
216 | operating system command) is processed. Cursor position and other state |
|
|
217 | information is up-to-date when this happens. For interoperability, the |
|

221 | |
|

222 | Be careful not ever to trust (in a security sense) the data you receive, |

|
|

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

234 | =item on_line_update $term, $row |

|
237 | screen output (e.g. underline urls or other useless stuff). Only lines |
|
|
238 | that are being shown will be filtered, and, due to performance reasons, |
|
|
239 | not always immediately. |
|
|
240 | |

242 | multiple rows. |
|
|
243 | |
|
|
244 | Please note that, if you change the line, then the hook might get called |
|
|
245 | later with the already-modified line (e.g. if unrelated parts change), so |

246 | you cannot just toggle rendition bits, but only set them. |
