@neilswann80 I'd be happy to have your feedback on this feature.

It's available from this pre-release: https://github.com/orontee/taranis/releases/tag/v1.2.0-rc1.

Nicely done. Was it difficult to implement?

What I did notice is that long swipes work 100% of the time, but smaller swipes (if holding one-handed for instance) weren't always acknowledged. Can the swipe distance to activate the page turn be reduced a little?

There's quite a large gap (red box) in the 8-day view now, between windspeed and rainfall. Looks to be an empty column. Is there a new feature appearing there?

Is if feasible to add the day/number of the month in the blue box?

Not really, around 100 lines. See: https://github.com/orontee/taranis/blob/main/src/swipe.h#L19.

What do you mean by "long"? Long duration or long distance? There are threshold for both in the code. I guess we'll have to find better values than the arbitrary I've chosen.

Don't know whether it works well with large screens...

Yep, see #42.

Long distance.

I'd guess it would be better to set a specific pixel distance rather than a percentage of ScreenWidth(). I'd think swipe distance is likely more uniform than the sizes of device screen (not sure how it's calculated... I'd need to stare at you code fpr a while to get my head around it)

Yes. But right now distance is expressed in pixels, resolution should enters the equation.

Ah yes, PPI between old and new devices could be quite different

Moon phase is another nice feature. I often like to run on an evening with a full moon, as strange as that may sound. Insomnia crossed with a smidge of lycanthropy I guess.

I'm having a headache creating an object of a class that has a member initialiser list... all I want to do is grab some variables from a class function to use elsewhere. If I leave the object uninitialized the compiler errors and if I initialise the object it compiles but program crashes. If I remove the object declaration it compiles and runs fine. Grrrrr. Driving me mad, but I'll get there. I'm very new to CPP, a keen tinkerer though. 😄

Hum alignment of columns is wrong (not surprising but so ugly)...

Worth adding a zero before all single digit numbers? But I guess not every number of the font is the same width anyway. And there's also cold weather figures with a - sign to account for.

[orontee]

Unfortunately since we're using a variable pitch font it's not that simple!

Yeah, could be done, #48.

Thinking of red box again, did you change units? Depending on the unit system, this space could be narrower. May be moon phase is not that important; I'll try to work on a better layout first, better in the sense that there are columns and space is evenly distributed between columns.

I am also thinking of wind direction in place of humidity. But it's another topic.
