extension-prometheus

Lua obfuscation using Prometheus. This extension hooks into the Lua builder plugin system in bob.

Installation

To use this library in your Defold project you need to make a fork of this repository and then add the repository archive URL to your game.project dependencies. Example (replace %YOUR_ORG% with your GitHub user or organisation):

https://github.com/%YOUR_ORG%/extension-prometheus/archive/master.zip

Prometheus config

The extension will look for a Prometheus configuration file named prometheus.lua in the project root.

Example

local test = require("main.test")

function init(self)
 print("hello")
 test.greet("Bob")
end

Prometheus source code

Prometheus source code is packaged into pluginPrometheusSource.jar and unpacked using getResourceAsStream() to a temporary folder while bob is running.
