Looking for 1.4 projects

s_federici

Now that Scratch is moving to 2.0 (but the 2.0 editor is still “dangerous”: I have lost a project one week ago…) it would be nice to have a way to identify 1.4 projects so that 1.4 users will still be able to take advantage of the incredible amount of available projects without having to enter each single project to see if the “share to” section contains a downloadable source.

Is there a way to quickly look for projects developed with the 1.4 (or previous) version?

I think you can determine in an automated fashion whether a given project is 2.0-only using the following API:

http://scratch.mit.edu/internalapi/project/10043508/get/

Which I believe returns 404 if it's a 1.4 project, and the JSON file if it's a Scratch 2.0 project. (Replace “10043508” with the project's ID.)

However, I don't think there's any way you can obtain a list of projects that have 1.4 files.

Btw, I have told you about the Retro Converter, haven't I? It lets you convert a Scratch 2.0 project back into a 1.4 one, as long as you haven't used any of the new blocks.

Thanks a lot! This is really enough for me

Is there a place where this api is described?

No. You haven't. And this is GREAT news!

BTW, is there a standalone version too of this amazing tool?

Thank you! There is, but it's command-line only, sadly. I can tell more if that doesn't put you off.

EDIT: Whoops, ignore this post.

It doesn't

Go on!

Thankfully, I've already written some OS-specific install instructions.

Once installed, create a quick Python file, ‘convert.py’:

#!/usr/bin/python
import sys
import kurt

inpath, outpath = sys.argv[1:]
kurt.Project.load(inpath).save(outpath)

At some point I'll make sure a version of this script is included with Kurt.

Then you can use it like this:

$ convert.py input.sb2 output.sb

Hopefully that works; let me know how you get on.

Thanks a lot! I will let you know for sure
