Dark mode? about flashlight

I'd lean towards setting an environment variable that plugin scripts can then read out with and present different HTML as necessary, to avoid duplicate plugins.
I'm sure it's possible to tease out whether dark mode is on or off via some internal Spotlight method, but does anyone know if there's an official API for telling if dark mode is enabled?

It is a key in the domain NSGlobalDomain of NSUserDefaults in OS X:

NSDictionary *dictionary = [[NSUserDefaults standardUserDefaults] persistentDomainForName:NSGlobalDomain];
id style = [dictionary objectForKey:@"AppleInterfaceStyle"];
BOOL isDarkModeOn = (style && [style isKindOfClass:[NSString class]] && NSOrderedSame == [style caseInsensitiveCompare:@"dark"]);

Haven't tested since the developer previews, and not on my Mac to test right now, but don't see why [in theory] it shouldn't work.

Seems to work.
In that case, you can just check for it in the plugin's Python script. Something like this:

def dark_mode():
  import Foundation
  return Foundation.NSUserDefaults.standardUserDefaults().persistentDomainForName_(Foundation.NSGlobalDomain).objectForKey_("AppleInterfaceStyle") == "Dark"
