📥 Installation

📄 Scripted installation

Requirements : git, node, zip,

Install scratch files & poppy's extension

We need scratch-vm and scratch-gui repositories to create our application, we download and install them with install-scratch-files.sh script. Then, we install our Poppy extension with install-extension.sh script.

bash install-scratch-files.sh
bash install-extension.sh

Exporting application

To use scratch with Poppy without having to use node on the raspberry, we export static files we just built as an archive. The archive will be uploaded as a release of poppy-scratch repository, and can be downloaded if the user wants to use Scratch.

bash export-scratch.sh

⌨️ Manual installation

Scratch VM and Scratch GUI installation

First, you will have to clone scratch-vm and scratch-gui and to link both. For this, open a Command Prompt or Terminal in your development environment and follow the next steps:

git clone https://github.com/LLK/scratch-gui
git clone https://github.com/LLK/scratch-vm
cd scratch-vm
curl -sL https://raw.githubusercontent.com/creationix/nvm/v0.33.11/install.sh -o install_nvm.sh
bash install_nvm.sh
source ~/.profile
rm install_nvm.sh
export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"  # loads nvm without reopening a terminal
nvm install 10.21.0
nvm use 10.21.0
npm install
npm link
cd ../scratch-gui
npm install
npm link scratch-vm

Then you will need to install Poppy's extension in Scratch files. In scratch-poppy run:

bash install-extension.sh

Building application

To build the application, go to scratch-gui folder and run :

sudo npm run build

Exporting application

To use scratch with Poppy without having to use node on the raspberry, we export static files we just built as an archive. The archive will be uploaded as a release of poppy-scratch repository, and can be downloaded if the user wants to use Scratch. To export the application as a zip archive, we need to rename the build folder as scratch-application in scratch-gui.

mv build scratch-application

Then zip it:

zip -r scratch-application.zip scratch-application

📝 Edit Poppy's Extension

You can add more blocks by modifying scratch_vm_files/scratch3_poppy files. You can find information to create a block here: https://github.com/LLK/scratch-vm/blob/develop/docs/extensions.md

To see and test your blocks run the script install_extension.sh and then go to scratch-gui folder. You can either:

• run a server that will auto reload Scratch server each time you run the install_extension.sh script. For this, run:

  sudo npm start

  Then go to http://localhost:8601/ in your web browser. Make sure to install the Poppy extension in the extension menu (button in the bottom left corner).

• build the static files and open index.html with your browser. You will have to run those steps each time you run install_extention.sh script.

  sudo npm run build
  cd build
  firefox index.html  # Or google-chrome, chromium-browser, ...

📜 Todo

• Implement the button "sequentially" and "play sequentially". These buttons allow playing different actions, for the first one, and moves, for the second, one after the other.
