What file format will be Scratch 2.0 using?
We (the meow team) are making a text-based Scratch so people can edit .sb files without the laggy block interface. blob8108 already made an awesome python module (kurt) to edit .sb files, but this would be extremely useful to know what format 2.0 will be using, as we want to prepare ourselves

A new format. Binary is all that's disclosed. So don't get you're hopes up. (nothings really disclosed)

If 2.0 has to read 1.4, I'm guessing it will have the same format as always...

Re: What file format will be Scratch 2.0 using?
It's a binary file with extension .sb2 in the prealpha.

Is it openable by 1.4?

Re: What file format will be Scratch 2.0 using?
Hmm... where'd the rumours that it's a binary come from?
It's basically just a zip file that contains a .json and the assets it needs (images, sounds, etc.). It'll be: .sb2
We won't be releasing a spec very soon though (we want to make sure we have it right, and dont have to make many changes, first). But I imagine we will release it when we release 2.0.
Sb2 files will not be openable by Scratch 1.4. (Because time travel is not currently possible. 
If it was, we'd go back and write the support for it into Scratch 1.4!)

Re: What file format will be Scratch 2.0 using?
you could add an extention to 1.4 to read .sb2 files but unsupported blocks may be a problem
!!!When it comes to Scratch2.0 I am totally like freaking out!!!

Well, I guess innovation has a price. Even Microsoft didn't think about supporting future versions of Office when it released 2002
I hope you're thinking about adding future compatibility in 2.0 though...

well, zip files ARE binary, aren't they? 
anyway, sounds better than the clutter in .sb

Yeah, they should release 1.4.2 now, so anyone downloading it now and not using 2.0 when it comes out would still be able to open uploaded projects.

That's a good point. They should release a "double-reader" version now that keeps support for 1.4 but saves it 2.0 -- just to minimise the damage! I guess that would take up too many resources though, and that's not something the Scratch Team have a lot of.

Maybe converter would work, to convert sb to sb2 and vice versa

It only includes that information if imported from a .sb

Converting sb to sb2 works simply by opening sb in 2.0 and saving it. For the other way round, maybe they will allow an export feature to export it to the old format. Otherwise I don't think it will be easy to convert.

Re: What file format will be Scratch 2.0 using?
What's exciting about the new format is that it'd be super simple to create Scratch 2.0 viewers in other languages like HTML5/Javascript + PHP;; just unpack the zip, check the MD5s, and parse the JSON file.
