feat: scripts to install or update uosc with a single line

[tomasklaen]

I haven't tested the script for Linux & macOS. If anyone could, it'd be nice :) It should install current latest stable.

I also want to figure out if we can provide a uosc/update command that people can just run from their menu and update uosc in the background.

Can't test on mac, but this is required for linux.

Is there no way in mpv to spawn an async subprocess that won't freeze the UI and listen to its stdout and exit events with callbacks?

[christoph-heinrich]

There is mp.command_native_async which I use in quality-menu.

[tomasklaen]

I completely missed that 😐. I guess we are not able to listen on stdin messages, and we get the whole thing at the end? Well, better than nothing.

I'll add a self-updater in a separate commit if I manage to make it work right. I'll merge this now so hopefully someone tests it on mac, because I absolutely do not want to try virtualizing that again.

I think it's possible to start a process directly from lua and then treat it's stdin and stdout like a file, but I never tried that myself.

What do you mean by this? Make the process output into a file with command > file.txt and read the file periodically?

Dunno why I always assume we don't have access to stuff like this in here. But I can't find any docs, or snippets on how to use it asynchronously without blocking the thread.
