I actually also tried to check for

process.env.HWVERSION == 2

and it didn't work.

Got it with the settings. It seemed to be necessary to assign the default clock again in the settings. Thank you all for those many hints!

YAY, now it worked.

That is soooo strange!
I have the

const BANGLEJS2 = process.env.HWVERSION == 2;

at the top of my code.

console.log BANGLEJS2;

shows "true".
But the following "if (BANGLEJS2) { " is not entered! No clue what happens there.

When I remove the check fpr BJS2, it works.

Another problem is that I get

Uncaught Clock has no widgets, can't fast load

When leaving the launcher despite i do load and show widgets at the end of my code.

Same result. I tried out to put the whole Bangle.setUI({ block underneath.

Then I get

Uncaught ReferenceError: "onDrag" is not defined
 at line 12 col 802 in hworldclock.app.js
...ngle.removeListener('drag',onDrag);Ba­ngle.removeListener('on...
                              ^

No, it doesn't. I get no error with the attached code. But the Listener isn't deleted. So it's basically the same as with the first try. I can load the watchface but when the launcher is called, the rotation is still happening on swipe...

I actually removed the function as it was obsolete anyway - with the same result.
See attached file.

Thanks for your patience!

    if (onDrag !== undefined) Bangle.removeListener('drag',onDrag);

gives me

Uncaught ReferenceError: "onDrag" is not defined
 at line 12 col 770 in hworldclock.app.js
...ut);drawTimeout=undefined;if(onDrag!=­=undefined)Bangle.removeListener('drag',­on...
                                                 ^

https://banglejs.com/apps/?id=widbt_noti­fy does this pretty good. It can be set to buzz when connection is lost. So when I leave the house without the phone, I get notified.

Then I actually get

 build: apps/hworldclock/app.js#L317
Invalid typeof comparison value

I now changed it to

Bangle.setUI({
  mode : "custom",clock:true,
  remove : function() {
    // Called to unload all of the clock app
	if (typeof PosInterval === "undefined") {
		console.log("PosInterval is undefined")
	} else {
		if (PosInterval) clearInterval(PosInterval);
	}	
    PosInterval = undefined;
    if (drawTimeoutSeconds) clearTimeout(drawTimeoutSeconds);
    drawTimeoutSeconds = undefined;
    if (drawTimeout) clearTimeout(drawTimeout);
    drawTimeout = undefined;	
	if (typeof onDrag !== "undefined") Bangle.removeListener('drag',onDrag);
	if (typeof onLock !== "undefined") Bangle.removeListener('onLock',onLock);
  }});

Now, the loader shows up, but the Listener seems to be still in place.

I attached my current code.

Current log shows:

                              ^

How do I resolve this?

However, development is very difficult for me as I do not understand certain things. E.g. when I want to check the interaction between the watchface and the loader, the easiest would be to just upload my watchface to the storage. But when I do that via IDE, I get strange errors from the watchface that I don't get when it is uploaded to RAM:

Uncaught Error: Module Font5x9Numeric7Seg not found
 at line 15 col 29 in hworldclock.app.js
require("Font5x9Numeric7Seg").add(Graphi­cs);
                            ^

How do you work with the web ide if you need to check with a launcher, your app and the emulator? Do you upload the launcher files manually to the enulators storage?

PS: I will do the revert. Never mind. Sorry for any inconvenience.

Revert this PR? https://github.com/espruino/BangleApps/p­ull/2369

Yes, please!

@Gordon could you do me a favor and revert this whole PR?

Also I'm really wondering why the watchface is still loaded when the launcher is shown. How do I kill my
Bangle.on("drag", e => {
when user presses the button for the launcer?

Not that familiar with git and I'm afraid I would break something. I now discovered the problem that I cannot use the launcher anymore. Did not notice that before. Will work on this eventually but for now I got no time :(
@Serj will hopefully consider the 90° then :)

Yes, I guess I could. I'll let this as is for now. Maybe I'll add a toggle for BJS1 later.

The screen won't automatically swap back when the next app loads (since it's set up so left-handed users can permanently keep their watch in that state), so you'll need to implement a handler for the Bangle.on('kill', ...) event to call g.setRotation(0) to put it back.

Actually now that I tried it out on the watch I find it better to not reset this when exiting. It's a neat feature to change global orientation quickly :)

As there is no g.getRotation, how do I determine the current set rotation?

OK, will look into it, thanks a lot!

Just out of curiosity, is there a way to rotate the screen 180° and keep it rotated until the watchface is unloaded (e.g. when the loader shall show up)?

I'm tempted to add a feature to my watchface that if it's unlocked you would swipe up to roate the whole screen to show the time to another person and swipe it again to have the normal mode.

Yes, exactly, it's usually quite easy. I guess maybe it would be possible to use the Github API to dig out who the authors were in an easy way? Or maybe there's a page I could just link to as I know GitHub lists icons for the top authors at the top of the directory list usually.

I know that GIT has this feature. But to see it in the app loader would be just much more convenient. And if I do a quick patch I don't want to appear as the maintainer.
I'd be ok with an optional field in the json. That way a maintainer also can intentionally set an app as "free to take over" for any other user because he doesn't want to maintain it anymore.
The patch approach is very interesting, but I also doubt the user would understand.

I just want to encourage developers to get in contact with each other before they just make a new fork to implement a small feature that could have been an option in the settings :)
Making a fork is very easy - implementing a feature to other developers apps is more a communication thing some people might just want to skip.

My intention was more the developer to developer perspective. Say, when I want to add a feature to an app, I maybe would like to ask the maintainer if adding it would fit in his global concept of the app. Otherwise I would just add a fork of the app and take control. That might also reduce the amount of forks. Many forks may confuse the user. E.g. we have multiple BT status widgets and in future multiple message apps maybe...

Would it make sense to add a maintainer property to the metadata.json?
That could be a foum user name or a clear name of the app/watchface main maintainer(s) or a value like "not set", "anonymous", "free to take over". If it's a user name, we could even link from the app loader to the forum.

Thanks for those suggestions.
Implemented most of them here

Though, I am still not sure with the variables as I use some of them globally, so I use var instead of let. What's the best practice on that?
(Sorry, I don't want to hijack this conversation for noob programming questions)

You mean for hworldclock itself after the merge?

yes.

Actually works only once, it seems some more cleanup is needed

Bummer, I hoped it was easier. Could you guys help me to tidy up the watchface somehow?
It might look as I'm a programmer, but most I do is copy&paste (like a senior programmer - but without the background knowledge :) )

Cool, looks promising... https://github.com/espruino/BangleApps/p­ull/2280
