|
|
212 | |
|
|
213 | Called whenever the B<ESC ] 777 ; string ST> command sequence (OSC = |
|
|
214 | operating system command) is processed. Cursor position and other state |
|
|
215 | information is up-to-date when this happens. For interoperability, the |
|
|
216 | string should start with the extension name and a colon, to distinguish |
|
|
217 | it from commands for other extensions, and this might be enforced in the |

|
|
219 | |
|
|
220 | Be careful not ever to trust (in a security sense) the data you receive, |

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 |
|

|
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. |
