====== S2C Packet 8: Context Clear ======

Informs the client that a part of the context has been cleared.

This packet can mostly safely be ignored if the client manually clears contexts where sensible, e.g. when switching channels or reconnecting. In the original PHP implementation, and thus other implementations, only mode ''%%3%%'' is ever used when switching channels with [[sockchat:commands:join|/join]].

===== Format =====

^ Index ^ Type ^ Description ^
|  0 |  ''%%8%%''  | Context Clear packet ID |
|  1 |  [[sockchat:types#int|int]]  | Context Clear mode |

===== Modes ======

^ Mode ^ Description ^
|  ''%%0%%''  | Only the message list has been cleared. |
|  ''%%1%%''  | Only the user list has been cleared. |
|  ''%%2%%''  | Only the channel list has been cleared. |
|  ''%%3%%''  | Message and user lists have been cleared. |
|  ''%%4%%''  | Channel, message and user lists have all been cleared. |

===== Examples =====

All lists have been cleared:
