Subject: [PATCH] AsyncTabCompleteEvent
|
|
|
|
Let plugins be able to control tab completion of commands and chat async.
|
|
|
|
This will be useful for frameworks like ACF so we can define async safe completion handlers,
|
|
and avoid going to main for tab completions.
|
|
|
|
Especially useful if you need to query a database in order to obtain the results for tab
|
|
completion, such as offline players.
|
|
|
|
Also adds isCommand and getLocation to the sync TabCompleteEvent
|
