147 | Very perl extension is a perl class. A separate perl object is created |
|
|
148 | for each terminal and each extension and passed as the first parameter to |
|
|
149 | hooks. So extensions can use their C<$self> object without having to think |
|
|
150 | about other extensions, with the exception of methods and members that |
|
|
151 | begin with an underscore character C<_>: these are reserved for internal |
|
|
152 | use. |
|
|
153 | |
|
|
154 | Although it isn't a C<urxvt::term> object, you can call all methods of the |
|
|
155 | C<urxvt::term> class on this object. |

272 | Called whenever text is about to be output, with the text as argument. You |
|
|
273 | can filter/change and output the text yourself by returning a true value |
|
|
274 | and calling C<< $term->scr_add_lines >> yourself. Please note that this |

|
284 | |

285 | Called whenever a line was updated or changed. Can be used to filter |

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

288 | not always immediately. |

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

712 | further programming. The only exception is that you cannot wait on |

|
|
714 | is that you cannot use blocking APIs, but the non-blocking variant should |
|
|
715 | work. |
