|
<p>Very perl extension is a perl class. A separate perl object is created |
203 |
|
|
for each terminal and each extension and passed as the first parameter to |
204 |
|
|
hooks. So extensions can use their <code>$self</code> object without having to think |
205 |
|
|
about other extensions, with the exception of methods and members that |
206 |
|
|
begin with an underscore character <code>_</code>: these are reserved for internal |
207 |
|
|
use.</p> |
208 |
|
|
<p>Although it isn't a <code>urxvt::term</code> object, you can call all methods of the |
209 |
|
|
<code>urxvt::term</code> class on this object.</p> |
210 |
|
|
<p>It has the following methods and data members:</p> |

213 |

</dt> |
214 |
|
|
<dd> |
215 |
|
|
Returns the <code>urxvt::term</code> object associated with this instance of the |
216 |
|
|
extension. This member <em>must not</em> be changed in any way. |

<dd> |
222 |
|
|
Dynamically enable the given hooks (named without the <code>on_</code> prefix) for |
223 |
|
|
this extension, replacing any previous hook. This is useful when you want |
224 |
|
|
to overwrite time-critical hooks only temporarily. |

<p>The sole purpose of this class is to deliver an interface to the |
580 |
|
|
<code>AnyEvent</code> module - any module using it will work inside urxvt without |
581 |
|
|
further work. The only exception is that you cannot wait on condition |
582 |
|
|
variables, but non-blocking condvar use is ok. What this means is that you |
583 |
|
|
cannot use blocking APIs, but the non-blocking variant should work.</p> |
