My GitHub tool-chain is now at the point where I use it for all of my Scratch projects. By running a batch file it -

• downloads the latest sb3 for a project
  
• converts all scripts into text
  
• extracts all assets (costumes and sound effects)
  
• opens GitHub Desktop
  
• asks for a commit comment and commits everything to GitHub
  

The entire conversion process is done via JavaScript and PHP so will work on any computer. I've currently only made a batch file that supports Windows 10. If anyone edits it for other systems then I'll happily add it to the repo.

The set-up is extremely simply (assuming you're already a GitHub user). The GitHub repository contains everything you need (which is basically a batch file) and includes full set-up instructions.

It makes it absolutely trivial to (a) ensure you always have backups and (b) track back if problems have been introduced or you want to see how and when changes have been made. The following examples make this clearer.

Examples of commits demonstrating how useful this is

Commit comment: Fixed sound channel 0 (noise) pitch control



Commit comment: Increased the contrast of the project's thumbnail



Example taken from a commit that involved variable values changing

Wow, neat! This looks extremely useful! Once I get back into making games, I will definitely be taking a closer look at using this.

Wow that's cool! Automating tasks saves a ton of time!

Are you using this just to make backups / compare versions? Because the Terms of Use are pretty clear about not sharing projects created with other tools.

Why is that in the TOS? Isn't the TOS outdated? Does this mean you can't share projects that were programmed in Turbowarp?

It sounds like it, yes.
Also anyone who uses a certain browser extension is breaking the TOU…?

well technically they're still using the scratch editor. also referencing https://scratch.mit.edu/discuss/topic/284272/, you're still allowed to use browser extensions.
I think Turbowarp is kind of a grey area though

It serves two purposes -

1. It backs up the sb3 in addition to all individual assets (graphics and/or sound files) so you can always roll back to whichever version you want
   
2. It parses the JSON scripts into pseudo code so that they can be used effectively in a source control environment
   

An example of a project I've worked on using this for backups and diffs can be seen in my GitHub repository here

The first post in the thread shows that it's solely for development purposes allowing you to use GitHub for Scratch projects in the same way you would use it for conventional computer languages. As far as I can see it doesn't contravene any TOU.

Delete the whole post if you must. I made the tool for my own use. It just so happens that I find it so extremely useful that I felt I would offer it to other Scratchers.

But it modifies the scratch editor though. That’s literally what it does.

I guess you're right.

It doesn't modify the editor's source code, which appears to be what the part of ToU is about. And I don't think it's “pretty clear”: it only allows projects created with the online editor (“the Scratch website editor”) or Scratch 1.4 (“an unmodified copy of the Scratch editor compiled from the source code described in Section 5.3” – section 5.3 contains a link to the 1.4 source code). This means that any project created using any version of the offline editor other than 1.4 is technically against the rules. I don't think people often report projects for not being made using Scratch.

What exactly is the point of this rule, anyway? It seems difficult to enforce in practice if the project isn't too much different from a “regular” project. I assume that its main purpose is to preserve equality by making sure that nobody can gain an advantage from “hacked” blocks or tools like a preprocessor.

Therefore, I think that if the tool doesn't provide abilities in excess of those of the Scratch editor, and doesn't produce a “broken” project, then nobody will be able to tell and nobody will have any reason to care. You could also argue that a text-based format for Scratch makes it much easier to use tools like find-and-replace or even a general-purpose preprocessor. However, if the tool greatly impacts how Scratch code is produced then there should be telltale signs of its use.

However, this is just my interpretation; the ST's interpretation is obviously more important.

I just used this for StackLisp, and it's pretty cool! https://github.com/MystPi/stacklisp

Also, is your sb3 to txt program open-source? I would love to take a look at it.

I'm glad you've found it useful. I have to admit that I'd hate to work on any large Scratch project without using this. The sb3-to-txt repository isn't open source at this point.

Thanks for making & sharing this. It's really useful, and I've been having a good play. The ability to version control scripts is great! I have a few observations…

I'm getting an HTTP 403 error when using the sb3-to-txt autosave function. The scripts are generated, but it then fails inside the buildSB3 function:
GET https://cdn.projects.scratch.mit.edu/531881458/ 403 (Forbidden)
I've tried your BBC emulator project in addition to some of my shared projects - same result. Could this be something on my side?

I also noticed a few things in the generated scripts:

• ‘Change’ is spelt wrong in “Looks.ChengeSizeBy(x);”
  
• The ‘Play Note () for () Beats’ Scratch 3 block generates “Music.PlayNote(note ?? - probably legacy function from Scratch 2.0, 1);”
  
• Event broadcasts use double quotes around the message name, whereas receives do not, e.g.:
  Event.Broadcast(“title screen”);
  WhenBroadcastReceived(title screen)
  I guess message names are like variable names so shouldn't use quotes in either context?
  

One last observation - I (foolishly) used colons in some sprite names. The resulting scripts.zip includes filenames including those colons. 7zip extracts them ok, replacing the colons with underscores. But Python's shutil.unpack_archive generates a blank file, whose name is truncated (from the colon onwards). The easy answer is to not use colons in sprite names… but it may be worth substituting them (and other non-filename chars) in the generated script files/zip?

It's great to hear it's being used! On a large project I couldn't get by without it but it didn't get a great deal of traction with others. Understandable I suppose considering the general demographic.

From memory I think this is something I need to fix on my side (possibly broken when the Scratch API was updated). I'll try to get a little time to look into it today.

Great feedback - thanks!

I'll have a ponder about this…
