My take on the clipboard extension, idea from Nicolas Tomé

[Flappy25]

A simple extension for interacting with the users clipboard

Run without sandbox

class Clipboard {
    getInfo() {
        return {
            id: 'clipboard',
            name: 'Clipboard',
            blocks: [
                {
                    opcode: 'setClipboard',
                    blockType: 'command',
                    text: 'set clipboard to [text]',
                    arguments: {
                        text: {
                            type: 'string',
                            defaultValue: 'Hello, Scratch!'
                        }
                    }
                },
                {
                    opcode: 'getClipboard',
                    blockType: 'reporter',
                    text: 'clipboard',
                    arguments: {}
                }
            ]
        };
    }

    setClipboard(args) {
        const text = args.text || '';
        navigator.clipboard.writeText(text);
    }

    async getClipboard() {
        const text = await navigator.clipboard.readText();
        return text;
    }
}

Scratch.extensions.register(new Clipboard());
