|
* This example is free, and not covered by LGPL license. There is no
|
|
* restriction applied to their modification, redistribution, using and so on.
|
|
* You can study them, modify them, use them in your own program - either
|
|
* completely or partially. By using it you may give me some credits in your
|
|
* program, but you don't have to.
|
|
*
|
|
*
|
|
* This example 'guards' the channel against using abusive language. When
|
|
* someone says a bad word, it takes some action against him/her, taking
|
|
* in account the number of times the person uses it. The first time, it just
|
|
* warns the person through a private message, the second time it warns him
|
|
* publically in channel, and after the second time it will kicks the insolent
|
|
* out of the channel.
|
|
*
|
|
* To keep it simple, this example reacts only on 'fuck' word, however
|
|
* is is easy to add more.
|
|
*
|
|
* Features used:
|
|
* - nickname parsing;
|
|
* - handling 'channel' event to track the messages;
|
|
* - handling 'nick' event to track nickname changes;
|
|
* - generating channel and private messages, and kicking.
