This gave me a error:
textutils.unserializeJSON('{"Hello":"World"}')

Odd, this works perfectly fine for me. The test suite also has something similar:

What's the exact error you're getting?

I had downloaded the API with wget, because it has only lua code in one file and not downloaded the full jar. Maybe this is the reason.

Ahh yes, if you're trying to use the API in older versions of CC:T it may not work. We rely on a couple of features from #363.

You can try it out online using copy-cat, as that's built from the latest commit.

I use CCEmuX as my favourite emulator. Mybe we can craete a GitHub Action that builds a new Version of CCEmuX for every Coomit on CC-Tweaked.

CCEmuX can update CC:Tweaked itself, no? copy-cat is CCEmuX, anyway.

I want to tie CCEmuX's CC:T version to the latest actual release. However, it might be possible to automatically build development versions from master. I'd have to look into it - it's more tricky than copy-cat, but possible.

copy-cat is CCEmuX, anyway.

Nah, copy-cat does entirely its own thing, due to its ... rather odd build process.

It occurs to me that I now maintain (to some extent) three emulators, and none of them share any code. Woops.
