Re: [Vm-dev] SqueakJS for Scratch (was: Questions on scratchJS:

David T. Lewis
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

Re: [Vm-dev] SqueakJS for Scratch (was: Questions on scratchJS:

Bert Freudenberg
Hi Stefano,

it is possible to export your project to your hard disk:

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.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.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.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!

Re: [Vm-dev] SqueakJS for Scratch (was: Questions on scratchJS:

Bert Freudenberg
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.

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

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.

Cheers

Hi Stefano,

this is the problem I saw too. My guess is that it is a simple encoding bug somewhere. But I do not have the time right now to investigate, unfortunately.

Dear Bert,
I realized that I didn't check really everything. Indeed, I can open in ScratchJS projects that I created with Scratch 1.4, but I cannot reopen projects modified in ScratchJS, neither in ScratchJS nor in Scratch 1.4. I get the following error message in both cases:

Could not read project; file may be damaged
(key not found)

Is this a known problem? Is there a way to overcome this limitation?

Thanks in advance
