spigot-js

I wanted to play around with Nashorn after a friend told me how nifty it was. This small project is the result.

Yes, the code quality can be better, however it achieves it's goal and that's all I was aiming for.

Scripting

No protection is built into this plugin, you are responsible for any scripts you execute and are thus responsible for any consequences.

Do not run untrusted scripts.

Variables

You are able to access the following variables through standard JS syntax. The variables listed are provided by spigot-js, if you are looking for ones that Nashorn provides then please refer to the relevant documentation.

Variable Name	Description
__DIRECTORY__	The absolute path of the scripts directory located in plugins/SpigotJS.
manager	The ScriptInterface that the script uses to interact with the server.
server	The Server instance.
logger	The host plugin Logger.
events	A Map of aliases for the FQNs of Bukkit Event implementations.
plugin	The host Plugin.

Event aliases

In an attempt to make usage of the ScriptInterface class feel more like natural JavaScript I opted for on(String, function(event)) style code for subscribing to events. This approach would result in using something along the lines of the following code for subscribing to PlayerJoinEvent.

manager.on("org.bukkit.event.player.PlayerJoinEvent", function(event) {
    ...
});

Nobody wants to constantly type out event FQNs though, so we rounded up all the standard events and threw them into the events map!

manager.on(events.PlayerJoinEvent, function(event) {
    ...
});

Reloading Scripts

spigot-js also utilises the WatchService class to listen for filesystem events, this means that your scripts will automatically be:

• Loaded when a script file is created.
• Reloaded when the file contents are modified.
• Unloaded when the file is deleted.

You can also reload scripts manually by execute the reload-scripts command. You cannot disable automatic reloading at the time of writing.

More coming soon.
