Dear All, I have two questions about ScratchJS (that I think is an awesome project): - is it possible to run ScratchJS locally? I tried to run index.html in the SqueakJS-master\scratch folder, but I just got a black square in the upper left corner - can I open local projects in ScratchJS?
Thanks in advance for your help

I managed running ScratchJS locally by saving the page https://squeak.js.org/run/ to my PC and the dragging my Scratch.image into the page.
What I don't know is where the SqueakJS file system is stored. When I open the File>Open dialog I can see the SqueakJS and ScratchProjects folders. Where are they stored in my PC?
Thanks in advance

Hi Stefano,
I am changing the subject line to "SqueakJS for Scratch" because google sends me somewhere else for "ScratchJS".
I think that you are asking about running Scratch on Bert Freudenberg's SqueakJS, which is a modern Squeak virtual machine implemented entirely in JavaScript for HML5, rather than the traditional compiled virtual machines that run on operating systems such as Linux and Windows.
If I understand your question correctly, you are asking about how to run Scratch on SqueakJS locally on your PC, and you want to understand where the Scratch files are stored on your PC.
I do not have good answers to your questions but I am sure that others on this list can help. I am also CC'ing the squeak-dev mailing list where some of the real Scratch and SqueakJS experts reside.
Here are some useful links for SqueakJS information:

I think that you are asking about running Scratch on Bert Freudenberg's SqueakJS, which is a modern Squeak virtual machine implemented entirely in JavaScript for HML5
Correct
If I understand your question correctly, you are asking about how to run Scratch on SqueakJS locally on your PC
Yes. I partially solved the problem by downloading page https://squeak.js.org/run/ and by dragging my Scratch.image file into the page. ScratchJS runs apparently fine. I also partially solved the problem of running local files, by dragging the Scratch projects on the Scratch app running in SqueakJS
you want to understand where the Scratch files are stored on your PC.
Correct. So that I can easily open my old Scratch projects and I can send projects that I develop in ScratchJS to other people

Correct. So that I can easily open my old Scratch projects and I can send projects that I develop in ScratchJS to other people
UPDATE: I created and saved a project in the "SqueakJS" folder (the one shown in ScratchJS) and I made a full search in my PC. The file was not found. So, I guess projects are just saved in an internal SqueakJS DB? If it is so, this makes unfortunately ScratchJS useless for my purposes. And I have no sufficient javascript/smalltalk knowledge to try myself to change this behaviour (that I guess would possible in principle, as a lot of JS apps allow to save file locally).

Hi Stefano,
I think that your understanding is correct. SqueakJS stores files in an internal database, so the Scratch files that you saved do not appear directly on your PC.
I do not know if it possible to copy those files to the file system on your PC, but hopefully someone on the squeak-dev mailing list will have an answer.
Thanks for asking, Dave

Hi Stefano,
it is possible to export your project to your hard disk:
1. run ScratchJS via https://squeak.js.org/scratch/#fullscreen 2. Inside Scratch, click "Save" as you normally would, give it a name. I just did that and named mine "test". 3. go to https://squeak.js.org/run/ and scroll down inside the file box: [image: image.png] 4. click the "/Scratch/Scratch Projects/test.sb" link to download the project file.
To import an older project you simply drag-and-drop it into ScratchJS. Or drop it into the "run" page and then use Scratch's file dialog - you just need to navigate up to the right folder (Click "Computer" then "SqueakJS"):
[image: image.png]
When I just tested this it said the file was corrupted, not sure if that is a general problem or not. Someone should investigate - to get to the Morphic desktop, shift-click the loop in the R of the SCRATCH logo:
[image: image.png]
Feel free to file bug reports / feature requests at https://github.com/bertfreudenberg/SqueakJS/issues/
It would be relatively simple to make a proper stand-alone app out of this by packaging it via Electron, and using the actual file system instead of the in-browser file system. I just do not have the time for that currently.
Cheers!

Thanks a lot Bert! Everything worked as you described. It worked well in my "local" version too (that is the "run" page that I downloaded to my PC).
It would be very usefulif, when dragging the scratch.image to the box in the "run" page, Scratch would open in a new TAB. Is this an easy modification of the "run" page? Sorry if I ask you, I'm not an HTML/JS expert.

I just noticed that, whereas Scratch manages quite well projects whose size is more than 250MBs, it seems that ScratchJS cannot load projects bigger than 20MBs. Is this a limitation that can be overcome? I'm very interested to it as my students are developping multimedia projects that require a lot of memory.
Cheers Stefano

Hi Stefano, it is possible to export your project to your hard disk: 1. run ScratchJS via https://squeak.js.org/scratch/#fullscreen2.

I just did that and named mine "test".3. go to https://squeak.js.org/run/ and scroll down inside the file box: 4. click the "/Scratch/Scratch Projects/test.sb" link to download the project file.
To import an older project you simply drag-and-drop it into ScratchJS. Or drop it into the "run" page and then use Scratch's file dialog - you just need to navigate up to the right folder (Click "Computer" then "SqueakJS"):
When I just tested this it said the file was corrupted, not sure if that is a general problem or not. Someone should investigate - to get to the Morphic desktop, shift-click the loop in the R of the SCRATCH logo:

Correct. So that I can easily open my old Scratch projects and I can send projects that I develop in ScratchJS to other people
UPDATE: I created and saved a project in the "SqueakJS" folder (the one shown in ScratchJS) and I made a full search in my PC. The file was not found. So, I guess projects are just saved in an internal SqueakJS DB? If it is so, this makes unfortunately ScratchJS useless for my purposes. And I have no sufficient javascript/smalltalk knowledge to try myself to change this behaviour (that I guess would possible in principle, as a lot of JS apps allow to save file locally).

I think that you are asking about running Scratch on Bert Freudenberg's SqueakJS, which is a modern Squeak virtual machine implemented entirely in JavaScript for HML5
Correct
If I understand your question correctly, you are asking about how to run Scratch on SqueakJS locally on your PC
Yes. I partially solved the problem by downloading page https://squeak.js.org/run/ and by dragging my Scratch.image file into the page. ScratchJS runs apparently fine. I also partially solved the problem of running local files, by dragging the Scratch projects on the Scratch app running in SqueakJS

Glad you got it working, Stefano!
The SqueakJS VM currently has an artificial limit of 100 MB. This is not an actual limit, but just there to prevent bugs from filling up all the memory.
There is a line "this.totalMemory = 100000000;" in the JS file somewhere. You could try appending another 0 to that and see if it works.

Stefano, I'm curious why you wouldn't simply run the 'proper' Smalltalk version of Scratch? It will be a lot faster, easier to manage and avoids messing with web browser annoyances.
I spent a lot of time making improvements to the MIT original version in order to make it viable on the RaspberryPi SBCs and the code is completely open. If you're not familiar with using Squeak and loading packages I'm sure we can work out a way to get you a ready-built system.

Ah, of course. Related to a subject we have just been talking about - how to run 32bit images on 64 bit machines etc.
Happily we can solve this without any scary messing around since the source code can be loaded into a 64 bit image just as easily as into a 32bit one. Another nice bonus is that we get to keep all the Squeak goodness behind the scenes and can add new capabilities when needed.
Why do you particularly want the Scratch 1.4 ? MIT have moved on to Scratch 3, based on html5 or sometihng I don't care about. I certainly claim the 'real' stuff is better but I am of course biased.

Will this make possible to run the BYOB 3.1.1 image (https://snap.berkeley.edu/old_site/old-byob.html) too? I need to run also this app in order to show to my students how to build procedures.

Whereas Scratch 3 (and 2) are more performant, they lack a lot of features very important to me as a teacher, such as the "FOREVER IF" block, the position of the mouse pointer (Scratch 3), the possibility to easily shrink/enlarge/rotate the sprites by using the GUI buttons/menus, the possibility to easily see the full names of the sprites, a way to show a step-by-step execution, etc

Hi Tim, thanks for your offer. What I need is a way of running Scratch 1.4 on the new MacOS Catalina, that "banned" 32bit applications.

Hmm, I truly don't know about that. The best I can say right now is a definite maybe. I *think* I did run it a couple of times on a Pi but we're talking 5-6 years ago. The issue is likely to be making sure one can get all the sources for that and working out how to install changes that may clash with changes I made to create NuScratch. IIRC, Jens Monig wrote BYOB and he's around and a helpful chap.

Ah. Well I suspect NuScratch running on a current Cog VM will actually be many times faster than Scratch 3. I don't bother much with it (Scratch 3) but I've had quite a few messages from people that prefer NuScratch for speed and reliability. There are downsides though, of course. The main one is that recent tutorials will be Scratch3 based and may be confusing because of that. Another is that MIT turned off support for original-Scratch projects on their scratch.mit.edu website/forum and so you won't be able to share projects that way.
