Scratch Desktop for GNU/Linux?

MegaApuTurkUltra

Will there be a desktop version for gnu/linux? It's just electron right? Is there any technical reason it's not available?

$(".box-head")[0].textContent = "committing AT crimes since $whenever"

Was this paragraph there at the time?

When will you have Scratch Desktop for Linux?

Scratch Desktop on Linux is currently not supported. We are working with partners and the open-source community to determine if there is a way we can support Linux in the future. Stay tuned!

Edit: According to this they are planning to make a Raspberry Pi version of Scratch 3: https://scratch.mit.edu/users/thisandagain/#comments-52560393

I remember translating it, so yeah, it was there…

Of course, it's a Node.js app…
Should be ported easily to Linux since Chromium, FFMPEG is available on Linux…

By the way, why is the default install path AppData on Windows?

scratch-desktop is an electron app, repack it from

Scratch Desktop Setup 1.2.0.exe

I could run it on Fedora 29.

How about this?

I see no reason why it isn't supported. It's literally an electron app? Doesn't that mean the same source works on anything with electron (aka a browser)?

Game Over
You'll find me on @LastContinue from now on.

smrman

Yes, that's the goal of Electron…
A Node webapp inside the Chromium browser…
One code base, all major platforms supported.

So why is there no official linux port yet? Isn't it just another (few) command(s) in a build script?

Basicly you just build your electron app using generic javascript and the electron api (sometimes the react framework too, like in this case)
and you just throw up some electron npm commands to build your app to Windows, or to MacOs or Linux.

Windows build command (requires Visual Studio Builds Tools)

gn gen out/Release-x86 --args="import(\"//electron/build/args/release.gn\") target_cpu=\"x86\""

Linux arm64 build (Requires CLang, build-essential, gcc, etc…)

sudo apt-get install libc6-dev-arm64-cross linux-libc-dev-arm64-cross \ g++-aarch64-linux-gnu

For short, it just need other build tools and a bit of practice.
Could be easily done by continuous integration…

nice!

i also noticed this updater yaml config that pointed to a “scratch-desktop” repo on github - so I went to http://github.com/LLK/scratch-desktop but there was nothing there… Private repo or did someone write the config before actually making the repo exist?

Tried out your instructions from github on a Pi3B+ just to see if The Force was with me but lucked out at this point

On arch (btw i use arch) I believe there's an AUR package that does this all for you

$(".box-head")[0].textContent = "committing AT crimes since $whenever"

You say “default”, but is there a way to change this? If I'm installing Scratch Desktop in (say) an educational environment then installing for All Users would be smarter than making dozens of per-user installations.

smrman

No you can't.
But if you move the installation folder where you want, then create a sym link it is working perfectly…

You're right

Arch is my love <3

Related to this topic:
1) I found an Ubuntu educational fork for Scratch 3. You can download the zip file. It's in french but you can change the language.
http://www.ac-grenoble.fr/maths/scratch/

2) How to install Scratch2.0 on Raspberry PI
https://www.raspberrypi.org/blog/a-new-version-of-scratch-for-raspberry-pi-now-with-added-gpio/
https://github.com/NoMod-Programming/Whiskers/
https://infinitytec.github.io/Whiskers-Website/

An offline Scratch 2 editor is available for Raspberry Pi 2 or 3 systems. This doesn’t depend on Chromium, it requires an ARM7 processor or better; it will fail with a segmentation fault if you run it on ARM6-based boards.

sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade
sudo reboot
sudo apt-get install scratch2

Scratch 1.4 and Scratch 2 are both installed and available in the Programming menu. Scratch 1.4 will only load .sb files. Scratch 2.0 will be able to read the older .sb files or the .sb2 files it creates. The offline Scratch 2 editor can access GPIO pins. More at: https://www.raspberrypi.org/blog/scratch-2-raspberry-pi/

3) Scratch 2 + Docker/Singularity Container(I think it wotrks with Scratch 3.0):

On french forum
http://forum.primtux.fr/viewtopic.php?id=1585 you have a post about this subject

primtux4 is offered with scratch 1.4 fonctionnalities
scrtach 2.0 is optionnel but it is easy to install its

and with this post ( http://forum.primtux.fr/viewtopic.php?id=1585 ) you have a how to for installing scratch 3.0 on debian ( PrimTux-Debian9-amd64-CTP-Legacy-2018-11-29.hybrid.iso )

there is also a primtux distribution for raspberry with scratch 1.4 and scratch2.0

Some one can check out this for offline Scratch 3.0 for Linux
https://github.com/redshaderobotics/scratch3.0-linux
for ubuntu or debian based system

Take a look at Scratux, it is a new project that provides Free and Libre Open Source Linux binaries of Scratch Desktop for different distros
