How to Use Role Based Permissions

Nucleus supports "role" based permissions that automatically inherit all recommended permissions

This is one of two ways to assign permissions quickly. The alternative is using the /nucleus setupperms, which is described here. Do not use both.

Nucleus supports adding a “super” permission that grants all permissions recommended for a given user role.

Nucleus is not a permissions management plugin. Roles are simply a template you can apply to a permission group.

If you do not want Nucleus to use new recommended permissions when you update Nucleus, but wish to review this manually, use /nucleus setupperms instead.

The following permissions automatically grant role defaults:

  • nucleus.user that acts as a “super permission” for any permission labelled as USER in the permission tables
  • nucleus.mod that acts as a “super permission” for any permission labelled as MOD in the permission tables
  • nucleus.admin that acts as a “super permission” for any permission labelled as ADMIN in the permission tables
  • nucleus.owner that acts as a “super permission” for any permission labelled as OWNER in the permission tables

These do not, and will never, override any explicit permission that has been set.

As an example, you give your moderators the nucleus.mod permission. This, for example, gives them permission to enter staff chat. However, maybe you don’t want them to access this. If you set nucleus.staffchat.base as false, this will override nucleus.mod. The same can be said for parent permissions, if you set nucleus.staffchat to false, a check to nucleus.staffchat.base will return false, regardless of whether nucleus.mod is set.

While this is cleaner than using /nucleus setupperms, you must be aware of the following:

  • These “role” permissions will never be given by default by setupperms.
  • Any permissions added to Nucleus that fall into one of these roles WILL be granted by default if you have the role permission. It is the responsibility of the server owner to check for any new features that may be added to these roles.
  • /nucleus setupperms will continue to exist, and will not grant new permissions automatically if they are added in new releases (but will if you re-run the setupperms commands).

If you do not want to use the role permissions, this can be turned off in the config by setting core.enable-parent-perms to false and reloading.
