* **Per-world permissions/groups** - define user/group permissions that only apply on certain worlds (on BungeeCord, a connected Bukkit/Spigot instance is treated as a world)
* **Tracks / paths / ladders** - users can be promoted/demoted along multiple group tracks
* **Negated permissions and groups** - define special rules for certain users/groups
* **Full support for UUIDs, even in Offline Mode** - users can change their usernames without losing permissions. In offline mode, a single user has the same internal UUID across a network.
* **Permission data stored within MySQL in a json format** - easily integrate the LuckPerms backend into your other projects
* **Well documented** - API methods have comprehensive Java docs, it's clear what each method does.
You can define the settings for per-server permissions, the storage method and credentials within this file.
## Info
### Permission Calculation
Permissions are calculated based on a priority system as follows.
* Temporary permissions will override non-temporary permissions.
Example: if a user has a false permission set for "test.node", and a temporary true permission set for "test.node", the temporary permission will override the permanent one, and the user will be granted the true node.
* World specific permissions will override generic permissions.
Example: if a user has a global "fly.use" permission, and then has a negated "fly.use" permission in the "world_nether" world, the world specific permission will override the globally defined one, and the user will be granted the negated node (provided they're in that world, of course.).
* Server specific permissions will override generic/global permissions.
Example: if a user has a global "fly.use" permission, and then has a negated "fly.use" permission on the "factions" server, the server specific permission will override the globally defined one, and the user will be granted the negated node.
* Inherited permissions will be overridden by an objects own permissions.
Example: A user is a member of the default group, which grants "some.thing.perm", but the users own permissions has "some.thing.perm" set to false. The inherited permission will be overridden by the users own permissions, and the user will be granted the negative node (provided they're on that server).
Temporary permissions are checked each time a user/group is loaded, and when the sync task runs. This means if you set a temporary permission to expire after 30 seconds, it won't actually be removed until the sync task runs.
The only way around this is to decrease the sync interval.
LuckPerms has an extensive API, allowing for easy integration with other projects. To use the Api, you need to obtain an instance of the `LuckPermsApi` interface. This can be done in a number of ways.
As of version 2.0, LuckPerms roughly follows the standards set out in Semantic Versioning.
The only difference is that patch number is not included anywhere within the pom, and is calculated each build, based upon how may commits have been made since the last tag. (A new tag is made every minor version)
This means that API versions do not have a patch number (as no API changes are made in patches). API versions will be x.y, and each individual build of LuckPerms will follow x.y.z.
Command usage is printed to the console/chat whenever invalid arguments are provided. Simply typing /perms will list all commands a user has permission to use.
