A permission node is a string like 'permissions.build', usually starting with the name of the plugin. Refer to a plugin's documentation for what permissions it cares about. Each node should be followed by true to grant that permission or false to revoke it, as in 'permissions.build: true'. Some plugins provide permission nodes that map to a group of permissions - for example, PermissionsBukkit has 'permissions.*', which automatically grants all admin permissions. You can also specify false for permissions of this type.
Users inherit permissions from the groups they are a part of. If a user is not specified here, or does not have a 'groups' node, they will be in the group 'default'. Permissions for individual users may also be specified by using a 'permissions' node with a list of permission nodes, which will override their group permissions. World permissions may be assigned to users with a 'worlds:' entry.
Groups can be assigned to players and all their permissions will also be assigned to those players. Groups can also inherit permissions from other groups. Like user permissions, groups may override the permissions of their parent group(s). Unlike users, groups do NOT automatically inherit from default. World permissions may be assigned to groups with a 'worlds:' entry.
The cannot-build message is configurable. If it is left blank, no message will be displayed to the player if PermissionsBukkit prevents them from building, digging, or interacting with a block. Use '&' characters to signify color codes.
An example configuration file might look like this:
users: ConspiracyWizard: permissions: permissions.example: true groups: - admin groups: default: permissions: permissions.build: false admin: permissions: permissions.*: true inheritance: - user user: permissions: permissions.build: true worlds: creative: coolplugin.item: true inheritance: - default messages: build: '&cYou do not have permission to build here.'
