BTTActionHUDAttributedTitle / Creating com.apple.flat-rtfd

Discussion & Questions

Hello!

I used to show an HUD from a script using following code (Node.js):

let BTT = {
	async action(actionType, actionName, opts={}) {
		let url = `http://127.0.0.1:${BTT_PORT}/trigger_action/?json=` +
			encodeURIComponent(JSON.stringify({
				"BTTPredefinedActionType" : actionType,
				"BTTPredefinedActionName" : actionName,
				...opts,
			}))
			+ "&shared_secret=" + encodeURIComponent(BTT_SHARED_SECRET);
		await exec(`curl "${url}"`);
	},
	async showHUD(title, detail) {
		await this.action(254, "Zeige HUD Overlay", {
			BTTHUDActionConfiguration: JSON.stringify({
				BTTActionHUDTitle: title,
				BTTActionHUDDetail: detail,
				BTTActionHUDDuration: 0.9,
				BTTActionHUDBackground: "96, 96, 96, 255",
				BTTActionHUDSlideDirection: 0
			}),
		});
	},
}

If I remember correctly, the text color used to be white, however, now it is black. Anyways, I discovered, that you can use fully formatted text using BTTActionHUDAttributedTitle. It seems to be some com.apple.flat-rtfd pasteboard format, but how do I create that outside of a Cocoa environment? This is an example that I copied from text created in BTT itself.

PS: I forgot to mention, that BTTActionHUDAttributedTitle contains a base64-encoded string, the above example is obviously already decoded.
