@sdobz Looks good at first glance, thanks for dealing with 0.15, I was avoiding dealing with the update.

Long-winded thinking:

It looks like there's also some changes to recipes according to the set difficulty, so that might need to be added to officially support 0.15.

I'd like to try running my tests on 0.15, which will require changing test/assets/download-headless-data.js.

If this isn't enough to support 0.15, I'll add a disclaimer to the README for now.

Actionable steps:

• I'd like to merge your changes into a side branch instead of master, let's say named 0.15-compat-lua so the automated tests can run in Travis.
• In addition, I'd like to see the result of running the tests on 0.15 by changing download-headless-data.

If you want, I can deal with changing the MR target and trying the tests on 0.15 either tonight or early tomorrow.

Again, thanks for getting this started!

@sdobz Status update: I've added support for testing multiple Factorio versions in the test scripts, and am pushing that through now (#3). Without your changes, I am getting the by_pixel error.

Once #3 hits master, I'll see how the tests run 0.15.

@sdobz I've created the 0.15-compat-lua branch with your changes, and added testing 0.15 to the test configuration. Looks like everything passes! https://travis-ci.org/CodeLenny/factorio-recipe-extraction/builds/241562875 (It even improved code coverage!)

I've merged your code into master, and closed #1. I'll be rolling out a 0.1.1 release to NPM.

Thank you for contributing!

Excellent, thanks for your updates! I've been running into a plethora of issues getting server infrastructure onto .15, next up is https://github.com/mroote/factorio-server-manager

@sdobz You're welcome! Good luck getting everything up to 0.15.

Are you currently using factorio-recipe-extraction? I haven't seen anything that people have done with it yet.
