Is there a way to associate file extension with app?

Hey,

I would want to always open Markdown files .md with Visual Studio code instead of the default which is Xcode.

Is there a setting to change this behaviour using nix-darwin?

Thanks in advance 🙇

I'm pretty sure that this would require a new module. It's a challenging space: The bulk of these settings are stored in ~/Library/Preferences/com.apple.LaunchServices. It is possible to write to com.apple.LaunchServices/com.apple.launchservices.secure.plist using defaults write, but I believe the OS actually uses com.apple.LaunchServices.SettingsStore.sql as its source of truth, and it may be difficult to get the plist to update the DB without a reboot.

Does anyone have any insight into exactly how this works when the action is performed via the Finder?
