Bukkit4Clojure

This wrapper is for any developer who wishes to develop Bukkit using the LISP-based language Clojure.

Installation

Simply download from the Releases tab or download the current (WIP) source and install that.

Usage

Loading the plugin

Add this to your plugin.yml:

main: com.coalesce.bukkitforclojure.Main

And add this to your wrapper.yml:

clojure: yourns.yourclj

Your main clj file should also include the following method, which gets called before your onEnable if it exists, no matter you use the params or not:

(defn setData
  [^Main wrapperMain
   ^File dataFolder
   ^FileConfiguration config
   ^PluginDescriptionFile pdf
   ^Server server
   ^Logger logger] ; Will also be in Main/sLogger as a static method.
   )

Actual use of plugin

Standard methods like onEnable and onDisable are also allowed to be used:

(defn onEnable
  []
  (prn "o it enabled")
  )
(defn onDisable
  []
  (prn "o it disabled")
  )

Registering events

To register events you'll first need a method with an event as a param, whether it's type hinted or not:

(defn playerQuit
  [^PlayerQuitEvent event]
  (prn (-> event (.getPlayer) (.getName)) " has quit the server.")
  )

To now register this, you'll need to do this in the onEnable:

(defn onEnable
  []
  (-> (Main/getInstance) (.registerEvent PlayerQuitEvent (EventPriority/NORMAL) #(playerQuit %)))
  )

Register commands

To register commands, you'll need a pretty standard onCommand method somewhere, but it will only work for the commands you assign to the specific method:

(defn clojureCommand
  [^CommandSender sender
   ^Command command
   ^String label
   #^"[Ljava.lang.String;" args] ; Type hinting String arrays isnt possible, thus this workaround.
  (prn (-> command (.getName) (.toUpperCase)) " was executed!")
  )

And now onto actually registering the command, again in onEnable:

(defn onEnable
 []
 (-> (Main/getInstance) (.registerCommand "pluginYmlName" #(clojureCommand %1 %2 %3 %4)))
 )

And register the command like you always would in the plugin.yml. All exceptions thrown are catched with no output, thus a nice return statement.

Bugs

Currently we have no bugs which we know of as it hasn't ever been tested, at least for now.
