PCA Perms 0.1.0 (first release)

New

• Automatic groups: everyone is a student, and ops and PCA Classroom teachers are in the teacher group (both can be turned off). An admin group inherits teacher and has everything.
• Teacher group starting rules: the PCA mods' teacher commands, plus /gamemode, /tp, /give, /clear, /effect, /time, /weather, /title, /kick and selectors like @a. It doesn't include /stop or /op.
• Any number of extra groups, each with a chat prefix, colour, weight and inherited groups.
• Every command can be controlled: command.<name> permissions for every command from Minecraft and every mod, down to sub-commands (command.plot.admin.reset). Players' games only show the commands they can use.
• Forge permission handler: any mod using Forge's permission system asks PCA Perms.
• Wildcards: pcaplots.*, command.*, *.
• In-game editor (/perms): a Groups tab and a Players tab. Permissions are suggested as you type, rules flip with one click, and the editor shows what a permission comes out as for a player and why.
• /perms commands for everything the editor does, for the console and staff without the mod in their game.
• Name prefixes in chat and the player list, e.g. [Teacher] MrSmith.
• Saved in config/pcaperms/permissions.json, shared by every world, readable and editable by hand (/perms reload).
• Every change made in the editor is written to the server log.
