Show a widget only NOT on clock screen?

It looks like the widget already tries not to run for clock apps: https://github.com/espruino/BangleApps/blob/d9d5926416566762e59b953c745f989d23c9b334/apps/widclk/widget.js#L6

But Bangle.CLOCK is only set if the clock uses Bangle.setUI(), so maybe your clock app doesn't use that?

If that's the case, I guess we should modify the widget to (also) check using __FILE__:

(()=>{
  if (Bangle.CLOCK) {return;} // app used setUI('clock') or setUI('clockupdown')

  // app didn't call Bangle.setUI('clock...'), but might still be a clock, 
  // look at <appid>.info to make sure
  if (typeof __FILE__ === 'string') { // only exists since 2v09
    const info = require("Storage").readJSON(__FILE__.split(".")[0]+".info",1)||false;
    if (info && info.type==="clock") { // info can have no type (but then it isn't a clock)
      return;
    }
  }

  // current app is not a clock:
  WIDGETS["wdclk"]={...};
})();
