[B]GroupManager[/B] - The Permissions 2.x plugin sucessor.
[B]Version:[/B] v1.0 alpha-5

Yes, it has multiworld and [b][SIZE=7]multigroup users[/SIZE][/b] support now. When 1.0 final release, next step is database (SQLite/MySQL).

[SIZE=6]- Don't use both EssentialsGroupManager.jar and GroupManager.jar! Just choose one, because they are the same!
- Don't use both EssentialsGroupBridge.jar and FakePermissions.jar! Just choose one, because they are the same![/SIZE][/COLOR]

---

As the growth of this plugin is getting faster and faster, I needed to put multiword support the soon as I could.
Now it's here. And GroupManager is keeping all of it's good stuff! Did I say it is going to bring a lot more of new stuff too?

[B]Purpose of the plugin:[/B]
The purpose has changed. Permissions got better. But it still not enough. Why I did, and keep doing this?
I started it thinking that it would make me happy. Now it's because it will make YOU happy.

[B]Advantages against Permissions:[/B]
¥ User multigroup support.
¥ Full command list to change anything during game or thru the console.
¥ Good API to change things. You to change a player group you can do getPlayer(name).setGroup(getGroup(name))
¥ Exception nodes.
¥ It separates groups files from users files.

[B]New Features:[/B]
¥ User multigroup support(yay!)
¥ Multiworld support(meh).
¥ It has world permission mirroring(you can make a world nether having the same permissions of world2 instead of default world1).
¥ It saves only the files that will have contents changed.
¥ It separates groups files from users files.
¥ It cleans old backup files older than 24h.

[B]Previous Features(included):[/B]
¥ It has the same file format as Permissions, no need to get used with anything new.
¥ It comes with a fake Permissions plugin, that attaches GroupManager to all your permissions dependent plugins. No need to make any changes, nor update other plugins. Just adjust your permissions files and GO!
¥ Commands to change users permissions are REALLY on-the-fly(no touching files).
¥ It saves the permissions data periodically.
¥ It backups every file before overwrites.
¥ Tons of commands for complete user/group/permission management during game/console.
¥ It has a fantastic temporary permissions system, that let's you to make changes in users, with the possibility to go back at any time(and it never is saved on files).
¥ Negative nodes(aka '-'): You can take off specific permissions from users that have a full set.
¥ Exception node(aka '+'): Used when a user/group has a set of negative nodes, and you want to allow a specific one. 

[B]User's subgroups:[/B]  a brief explanation
You can see on the file structure(down here on same post), that users have an optional node called subgroups. That node is a list, just like "permissions" node. There you can list a user subgroup, it can be as many as you want.
What a user inherits from subgroups? [B]Only permissions.[/B] It means nothing on a subgroup's info node(prefix, suffix, build and other variables) will be considered. 
The user will still be considered as a member of that group, but will only inherits it's permissions, like some commands, kits, etc.

This reduces the needs of a nest of groups inheriting each other.
You can have one user in Peasant group, which has only some basics, and them let him join in Miner as a subgroup, where he can get Miner kits, or other related to miner group.
Later, when your town needs a railer, you can just add the group Railer to him as subgroup, and he will have both things at same time. When the job is done, you just remove the subgroup.
This gets even more interesting when you have groups related to towns, factions, teamsÉ etc.

[B]World mirroring:[/B] a brief explanation
Let's say you have a config file like this:
[CODE]settings:
  data:
    save:
      minutes: 10
  logging:
    level: INFO
  permission:
    world:
      mirror:
        world1:
          - world2
          - world3
        world4:
          - world5[/CODE]
It means that all your permissions of world2, and world3 will be the same of world1. And it means all permissions of world5 will be the same of world4.
It won't copy any file. In fact, it won't matter if there is files for world2É when the permissions get load, every request for world2 will be redirected for world3. Simple as that.

If no mirroring is specified, any world not loaded will automatically mirror the default world of the server.

[B]File structure:[/B] a brief explanation
The files read for GroupManager 1.0+ for data management are two files per world. The users file are [i]users.yml[/i]. The groups file are [i]groups.yml[/i].
The thing is that those files are located in:
plugins/GroupManager/worlds/[i]WORLDNAME[/i]

So the file structure for the world called [i]anjoCaidoWorld[/i] and [i]netherWorld[/i] will be:
[i]plugins/GroupManager/worlds/anjoCaidoWorld/groups.yml[/i]
[i]plugins/GroupManager/worlds/anjoCaidoWorld/users.yml[/i]
[i]plugins/GroupManager/worlds/netherWorld/groups.yml[/i]
[i]plugins/GroupManager/worlds/netherWorld/users.yml[/i]

The files might look like this:
groups.yml
[CODE]groups:

        default: false

You can see that the node structure are exactly the same used for GroupManager 0.99d(-) and Permissions, it means you can use the same files here.
[B]Note: Every node that doesn't make part of the respective file is ignored. So if you are migrating from older GroupManager or Permissions you can just duplicate your files as groups.yml and users.yml. When comes the time where is needed to save the file, all unused data for each file will be discarded. So you don't need to split files, just duplicate them with correct names, it will work.[/b]

[B]Negative and Exception nodes:[/B] a brief explanation
Let's say you have a group SemiAdmin like this.
[CODE]groups:
  SemiAdmin:
    default: false
    permissions: [+groupmanager.manpromote, -groupmanager.*,
      '*']
    inheritance: [Moderator]
    info: {prefix: '', build: false, suffix: ''}[/CODE]
You should read this way:
'*' -> means this group will have access to all commands.
'-groupmanager.*' -> Where all his commands of groupmanager where [b]removed[/b].
'+groupmanager.manpromote' -> [b]Except[/b] manpromote.

It means he can do everything that is not of GroupManager, AND manpromote.

It's like listing essentials.*, worldedit.*, worldprotect.*, everyotherthing.* and groupmanager.manpromote.

It gives a very big flexibility on permissions.

Note:
For every level of inheritance,
Every permission starting with '+' is tested first. Then comes permissions starting with '-'. Then comes normal permissions(including '*').

[B]Commands[/B]:
¥ Now on multiword support, every command will act only on the selected world.
¥ If none/invalid world is selected, it will run on the default world.
¥ If the world selected is a mirrored world, it will work on the mirror world.
(on next version, when a command involves a player, there will be a toggle that will automatically act on the victim(player) world is in)

All commands that changes permissions only allow you to change users below in a inheritance level(eg. Admins can't mod other Admins, but can modify Moderators).
Except for Console, he can modify anyone.

[B]So, what happens with all of these plugins that already use Permissions?[/B]
They will still work. I made a fake Permissions plugin, that will replace your old Permissions plugin. And the new fake one will attach directly on GroupManager system. So all plugins will think they are working with Permissions, but they will work with GroupManager.
The most incredible thing is that all those plugins will receive the benefit of instant changes.

[B]I'm a server Administrator, what should I do to use it?[/B]
If you already have Permissions, do this:
	1.	Remove Permissions.jar from you plugins folder. (leave the Permissions folder there, if it is named diferently than this, the automatic import will not work)
	2.	Paste GroupManager.jar with FakePermissions.jar on your plugins folder.
	3.	Run.
	4.	With all file structure done, you create your worlds folder and copy your files there.

All your old plugins will still work like a charm.

[B]I'm a plugin developer, how should I use this plugin?[/B]
You can read the java-doc, linked below. It's not complete yet, but it has the essential.
Here is some code examples...

Loading in your plugin:
[CODE]import org.anjocaido.groupmanager.GroupManager;
import org.anjocaido.groupmanager.dataholder.worlds.WorldsHolder;
import org.anjocaido.groupmanager.dataholder.WorldDataHolder;
public void onEnable() {
        Plugin p = this.getServer().getPluginManager().getPlugin("GroupManager");
        if (p != null) {
            if (!this.getServer().getPluginManager().isPluginEnabled(p)) {
                this.getServer().getPluginManager().enablePlugin(p);
            }
            GroupManager gm = (GroupManager) p;
            WorldsHolder wd = gm.getWorldsHolder();
        } else {
            this.getPluginLoader().disablePlugin(this);
        }
    }[/CODE]
WorldsHolder contains everything you need. You can easily do anything with it.

Here is a example of a plugin that in a special circumstance, needed to put the player in a special group, with no permissions at all.
[CODE]public void markAsNotLoggedIn(Player player) {
            OverloadedWorldHolder perm = gm.getWorldsHolder().getWorldData(player);
            Group lockDown = perm.getGroup("NotLoggedIn");
            if(lockDown == null){
                lockDown = perm.createGroup("NotLoggedIn");
            }
            perm.overloadUser(player.getName());
            perm.getUser(player.getName()).setGroup(lockDown);
    }[/CODE]From now on the user is in this special group. And every change on him is temporary. Until the code below is executed.
[CODE]public void restorePermissions(Player player){
            OverloadedWorldHolder perm = gm.getWorldsHolder().getWorldData(player);
            perm.removeOverload(player.getName());
    }[/CODE]

And, finally, how to check a user permission:
[CODE]public boolean canChangeGroup(Player player){
Ê Ê Ê Ê Ê Ê return gm.getWorldsHolder().getWorldPermissions(player).has(player,"groupmanager.mangroup");
Ê Ê }[/CODE]

[B]F.A.Q.[/B]
¥ [B]Q[/B]: It is compatible with permissions... but where it get it's data from?
- A: It gets from users.yml and groups.yml in the world folder, located properly inside GroupManager worlds folder.
¥ [B]Q:[/B] Can I use commands from other plugins to change permissions?
- A: No. I made the decision to store data in GroupManager folder because I don't think it is right my plugin mess around with other ones files. Unfortunately, other plugins of group modification tries to access other files than mine.
