Get all the available commands

Hello,
I'm trying to make a command logger, I'm using the "PlayerCommandPreprocessEvent" Event.
But the problem is that this event gets triggered everytime a player says a command, even for commands that don't exists.
Is it possible to get a list of all the available commands, including the commands from plugins so I can verify wich one actually exist?

 

I'm sure this is possible since Essentials does it for their /help command. Although I'm not too sure how they do it..

 

I guess you could scrape all plugin.yml files, but that would be inefficient I guess. I am sure there is a method to do this, as I saw some other plugins that retrieved all commands.

 

Yea, I know.
Thats why I asked how to do it since I knew it should possible .

 

when you know that essentials does it, you can take a look at the source of it and see how they've done it

 

I did, but I don't understand it.
I just started to learn how to make plugins and my java knowledge isn't that good either.

Help please.

You can use Bukkit.getPluginCommand(commandLabel) != null to test whether commandLabel is a valid command, but this only works for commands added by plugins.
In regards of the default commands i could only find Bukkit.getCommandAliases(), but the documentation is unclear about what it actually contains.

 

Thanks, this works for plugin commands however it doesn't work with every bukkit command but its a start.

 

There is a better way of doing it, but this is what I have:

Code:java

PluginManager manager = getServer().getPluginManager();
SimplePluginManager spm = (SimplePluginManager) manager;
List<Plugin> plugins = null;
Map<String, Plugin> lookupNames = null;
SimpleCommandMap commandMap = null;
Map<String, Command> knownCommands = null;
if (spm != null)
{
    Field pluginsField = spm.getClass().getDeclaredField("plugins");
    Field lookupNamesField = spm.getClass().getDeclaredField("lookupNames");
    Field commandMapField = spm.getClass().getDeclaredField("commandMap");
    pluginsField.setAccessible(true);
    lookupNamesField.setAccessible(true);
    commandMapField.setAccessible(true);
    plugins = (List<Plugin>) pluginsField.get(spm);
    lookupNames = (Map<String, Plugin>) lookupNamesField.get(spm);
    commandMap = (SimpleCommandMap) commandMapField.get(spm);
    Field knownCommandsField = commandMap.getClass().getDeclaredField("knownCommands");
    knownCommandsField.setAccessible(true);
    knownCommands = (Map<String, Command>) knownCommandsField.get(commandMap);
}
 
if (commandMap != null)
{
    for (Iterator<Map.Entry<String, Command>> it = knownCommands.entrySet().iterator(); it.hasNext())
    {
        Map.Entry<String, Command> entry = it.next();
        if (entry.getValue() instanceof PluginCommand)
        {
            PluginCommand c = (PluginCommand) entry.getValue();
            //"c" is the command
        }
    }
}

Edit: My formatting got screwed up >.<

 

I figured I'd revive this thread for those who need to know how to do this (it took me quite a while to figure this out)

Code:

for (HelpTopic cmdLabel : getServer().getHelpMap().getHelpTopics()) {
    getServer().broadcastMessage(cmdLabel.getName());
}

Have a nice day
