Subject: [PATCH] Console Command Completion
|
|
|
|
changed exception handling
|
|
wrapped the tab completion in a waitable to sync it with the main thread
|
|
Implement command tab completion in the console. Adds BUKKIT-4168
|
|
|
|
Even though JLine provides an API for tab completion, there was still now tab
|
|
completion for console commands.
|
|
This commit implements tab completion in the console by providing the
|
|
ConsoleReader with a Completer implementation.
