Yaml Config Files?

Um, ok. I'm pretty new to java, and I know some of you are probably gonna tell me I need to learn more before I get into proper programming, but I thought this would help me learn.

I'm making a plugin called OtherStuph, which is going to be a collection of commands which you may not find in Essentials, or things like that. Like /fire <username> which sets someone on fire, until the /unfire <username> command is used. Optional timeout parameter, so the fire disappears after x number of seconds.
Well, there was going to be a command /forum for people who have a forum they want their server users to visit. It's a disable-able command (that's coming later), and the forum link is set in the config file.
For example:

config.yml (open) config.yml (close)

Code:

forum:
    enabled: true
    link: http://myforum.com/

And then I want my plugin to read the link bit. I know you use a yaml loader or something, and you'd use forum.link or something, but I'm not entirely sure on the details.
I tried looking at other projects' source codes, but they're either too complicated for me to understand, or I have no idea where the yaml call is. :/

So yeah, here's my source code for the main plugin bit... I'd like the variable forumlink to become what the link should be please.

OtherStuph.java (open) OtherStuph.java (close)

Code:

package com.Nineza.otherstuph;

import java.io.File;
import java.util.HashMap;

import org.bukkit.command.Command;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;

import org.bukkit.util.config.Configuration;

/**

public class OtherStuph extends JavaPlugin {
    File f = new File(getDataFolder(), "");
    Configuration config = new Configuration(f);
    private final String forumlink = "ForumLinkHere"; //I want the forum link to be found over here
    private final OSPlayerListener playerListener = new OSPlayerListener(this);
    private final OSBlockListener blockListener = new OSBlockListener(this);
    private final HashMap<Player, Boolean> debugees = new HashMap<Player, Boolean>();

    @Override
    public void onDisable() {
        // TODO: Place any custom disable code here

        // NOTE: All registered events are automatically unregistered when a plugin is disabled

        // EXAMPLE: Custom code, here we just output some info so we can check all is well
        System.out.println("Goodbye world!");
    }

    @Override
    public void onEnable() {
        // TODO: Place any custom enable code here including the registration of any events

        // Register our events
        PluginManager pm = getServer().getPluginManager();
        pm.registerEvent(Event.Type.PLAYER_JOIN, playerListener, Priority.Normal, this);
        pm.registerEvent(Event.Type.PLAYER_QUIT, playerListener, Priority.Normal, this);
        pm.registerEvent(Event.Type.PLAYER_MOVE, playerListener, Priority.Normal, this);
        pm.registerEvent(Event.Type.BLOCK_PHYSICS, blockListener, Priority.Normal, this);
        pm.registerEvent(Event.Type.BLOCK_CANBUILD, blockListener, Priority.Normal, this);

        // EXAMPLE: Custom code, here we just output some info so we can check all is well
        PluginDescriptionFile pdfFile = this.getDescription();
        getServer().getLogger().info("[" + pdfFile.getName() + "] Version " + pdfFile.getVersion() + " successfully loaded!");
    }

    public boolean isDebugging(final Player player) {
        if (debugees.containsKey(player)) {
            return debugees.get(player);
        } else {
            return false;
        }
    }

    public void setDebugging(final Player player, final boolean value) {
        debugees.put(player, value);
    }
    @Override
    public boolean onCommand(CommandSender sender, Command command, String commandLabel, String[] args)
    {
        String[] split = args;
        String commandName = command.getName().toLowerCase();
        if(sender instanceof Player)
        {
            Player player = (Player) sender;
                
            if (commandName.equals("ostest")) {
                player.sendMessage("Hi there, " + player.getDisplayName() + "! =D");
                return true;
            } else if (commandName.equals("gettime")) {
                player.sendMessage("The time is " + player.getWorld().getTime() % 24000 + "!");
                return true;
            } else if (commandName.equals("forum")) {
                player.sendMessage("The forums are at: " + this.forumlink + "");
                return true;
            }
        }
        return false;
    }
}

And my plugin.yml, if you need it:

plugin.yml (open) plugin.yml (close)

Code:

name: OtherStuph
main: com.Nineza.otherstuph.OtherStuph
version: 0.01
author: Nineza
description: A bunch of useful stuff for Bukkit users.
commands:
    ostest:
        description: A test for the OtherStuph plugin
        usage: /<command>
    gettime:
        description: Find out the raw time after dawn
        usage: /<command>
    forum:
        description: Displays the link to the forums
        usage: /<command>

And sorry if I've made a real idiot of myself.

Thanks in advance!

 

Um, please? Someone help? D:

 

I want to know this too please

 

I made a Yaml file handler a few weeks ago, Im pretty new to java so my code is simple ^^

Code:

package com.SySammy.SyBot.UI;

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.util.Map;
import java.util.logging.Level;
import java.util.logging.Logger;
import org.yaml.snakeyaml.Yaml;

/**
*
* @author Sammy
*/
public class yamlHandler {

    private String cmd;
    private Object objd;
    private Object obju;
    BufferedReader input;

    public yamlHandler(String command) {
        this.cmd = command;
        try {

            input = new BufferedReader(new InputStreamReader(getClass().getClassLoader().getResourceAsStream("commands.yml")));


        } catch (Exception ex) {
            Logger.getLogger(yamlHandler.class.getName()).log(Level.SEVERE, null, ex);
        }
        Yaml yaml = new Yaml();
        Map<String, Map<String, Map<String, Object>>> data = (Map<String, Map<String, Map<String, Object>>>) yaml.load(input);

        if (command.equals(command)) {
            objd = data.get("commands").get(cmd).get("description");
            obju = data.get("commands").get(cmd).get("usage");
        }
    }

    public String getdescription() {
        return objd.toString();
    }

    public String getusage() {
        return obju.toString();
    }
}

My yml file is only for commands, but its a new one not the plugin.yml:

Code:

commands:
  help:
    description: Help menu
    usage: |
          /<command> - help menu.

Hope it helps

 

I'm new to java too, and I think there's a built-in class to the Bukkit api. :S
Anyone else heard of that?
But in the meantime, I'll try yours.
Thanks.

 

I don't think you can use the bukkit yml handler without recompiling bukkit

 

The Plugin interface (which JavaPlugin implements) provides a Configuration object via getConfiguration().
You don't need to create your own if you're getting/setting values in the config.yml for your plugin.

So you can get the URL like:

Code:

String url = getConfiguration().getString("forum.link");

And you can construct separate Configuration objects and use them as well for additional files.
No need to recompile Bukkit.

 

Ok, I just tried that thing. I can get stuff from the config, but I'm not sure how to save. Usually it's config.setString(), but when I tried that it said it didn't exist.
Any ideas? :S

 

To set values, use setProperty():

Code:

String url = "http://myforum.com/";
getConfiguration().setProperty("forum.link", url);
getConfiguration().save();

The save() method saves the changes you made to the file.

 

Yeah, I knew about save, but didn't quite work out about setProperty. It said object for the second argument, and didn't quite realise what that meant.
Thanks.

 

the only other thing to add is that if you want to load something other than config.yml you have to load it explicitly:

Code:

                String path = wName + ".config.yml";
                File f = new File(getDataFolder(), path);

                Configuration c = null;

                if (f.exists())
                {
                    c = new Configuration(f);
                    c.load();
                }
                _configs.put(wName, c);

That is how I load my world-specific configs.

 

Thanks! This works for me...

 

Bukkit uses a library called Snakeyaml

 

I've got another problem with bukkits YAML implementation:
