144 | |
|
|
145 | Very perl extension is a perl class. A separate perl object is created |
|
|
146 | for each terminal and each extension and passed as the first parameter to |
|
|
147 | hooks. So extensions can use their C<$self> object without having to think |
|
|
148 | about other extensions, with the exception of methods and members that |
|
|
149 | begin with an underscore character C<_>: these are reserved for internal |
|
|
150 | use. |
|
|
151 | |
|
|
152 | Although it isn't a C<urxvt::term> object, you can call all methods of the |
|
|
153 | C<urxvt::term> class on this object. |

168 | to overwrite time-critical hooks only temporarily. |

261 | |

269 | can filter/change and output the text yourself by returning a true value |
|
|
270 | and calling C<< $term->scr_add_lines >> yourself. Please note that this |

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

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

693 | C<AnyEvent> module - any module using it will work inside urxvt without |

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

|
695 | condition variables, but non-blocking condvar use is ok. What this means |
|
|
696 | is that you cannot use blocking APIs, but the non-blocking variant should |
|
|
697 | work. |
