What this does

It modifies forge to convert the old method of recipe-registering from 1.11 into the new JSON-format in an easy and (hopefully) painless way.

What this doesn't do

• It doesn't update your mod to 1.11, that would be very hard to do. It just automatically generates the recipe JSON files
• It doesn't "support" configurable recipes. It does generate the JSON files (as long as they're enabled when converting [see 'How to use this']), but they won't be made configurable. To update this behavior you'll have to use the IConditionFactory. This helpful forum post by Choonster is a good start.

Why would I want this

To make your life easier while updating your mod to 1.12. Especially if you have a lot of recipes.

How it works

It's actually very simple. Only 2 files have been modified: GameRegistry now extends GameRegistryExtension (who'd have guessed?) This extension class provides the old recipe-registering methods so your old 1.11-compatible recipe-registering code compiles perfectly. The implementation of this methods if different though, it generates the JSON for the recipe specified with the parameters and places them in a folder.

How to use this

I haven't quite figured this out yet (as I'm only on v0.0.0 and there isn't any actual implementation yet). It'll probably involve using a gradle plugin in addition to ForgeGradle with a task running your mod with this modified version of gradle.
