It would be great to have a single class that listens to the [onCommand](https://hub.spigotmc.org/javadocs/spigot/org/bukkit/command/CommandExecutor.html#onCommand%28org.bukkit.command.CommandSender, org.bukkit.command.Command, java.lang.String, java.lang.String[]%29) event and then calls our internal command methods (instead of creating tons of listeners for each command).

This would also allow us to throw our own error classes which we could catch, e.g:

NoPermissionError
InvalidArgsError
NotPlayerError
...

This would save us stuff like

def whatever_command(sender, args):
  if not is_player(sender):
    msg(sender, "&cOnly players can do this")
    return True
  whatever()

def foobar_command(sender, args):
  if not is_player(sender):
    msg(sender, "&cOnly players can do this")
    return True
  foobar()

instead we would do something like

def validate_player(sender):
  if not isinstance(sender, Player):
    raise MustBePlayerError()

def whatever_command(sender, args):
  validate_player(sender)
  whatever()

def foobar_command(sender, args):
  validate_player(sender)
  foobar()

It would be great to have a single class that listens to the [`onCommand`](https://hub.spigotmc.org/javadocs/spigot/org/bukkit/command/CommandExecutor.html#onCommand%28org.bukkit.command.CommandSender, org.bukkit.command.Command, java.lang.String, java.lang.String[]%29) event and then calls our internal command methods (instead of creating tons of listeners for each command).

This would save us stuff like ``` Python def whatever_command(sender, args): if not is_player(sender): msg(sender, "&cOnly players can do this") return True whatever() def foobar_command(sender, args): if not is_player(sender): msg(sender, "&cOnly players can do this") return True foobar() ``` instead we would do something like ``` Python def validate_player(sender): if not isinstance(sender, Player): raise MustBePlayerError() ``` ``` Python def whatever_command(sender, args): validate_player(sender) whatever() def foobar_command(sender, args): validate_player(sender) foobar() ```

New Event URL: https://hub.spigotmc.org/javadocs/spigot/org/bukkit/event/player/PlayerCommandPreprocessEvent.html

There is no such CommandExecutor event btw?

BTW: Console won't be able to use commands if we use the event up there ^

Well now its not an event, its a CommandHandler but yeah that'll do :P
I guess a command is still an event.
