This is the source code for the PlaceholderAPI expansion https://api.extendedclip.com/expansions/world/

UPDATE 1.2.2 Now is possible to put world between * to prevent bad world loading when world had _ in name.(%world_name_*world_the_end*%)

FORMAT CHANGED! As of version 1.1.0, this expansion has completely changed its format. For the full format changes, look at the link above

Note:

• For placeholders which has the argument <world>, you can name the argument to the specific world, or symbol "$" (without ") as local world
• For Vault-related placeholders, especially %world_players_<group>_<world>% and %world_totalbalance_<world>%, you need to have both Vault & one of economy provider plugin (e.g: EssentialsX) to work
