Updating LUA #385

Closed zwim closed 1 month ago

zwim commented 1 month ago

What is not working?

LUA is very outdated.

Crashes with BIG LUA files

Interpreting big LUA files takes too much memory.

Proposal

Update LUA-support to 5.4, include compiled (and not the original) LUA-files in firmware and automate this LUA-compilation.

Solution

You find my solution in -> https://github.com/zwim/open-smartwatch-os/tree/ZwilightWatchface

Showcase

The outer ring goes from 0 -> 24h; 0 o'clock is in the bottom.

The outer blue ring shows if the sun is over the horizon; the yellow markers show the different twilights (civil, nautical, astronomical). All this is calculated with a LUA script.

(Sidemark: Note how good the anti-aliased hands, indices and arcs look like!)

And now

If anyone has interest in using some educated LUA-scripts (or about twilight) please make a comment.

I think this is a really cool idea! I'm interested in merging this. Although, pre-compiled LUA - why not using C++ directly then? LUA has the advantage of being source-available and can be easily loaded from e.g. an SD-card, but by compiling you are removing that advantage.

You are right, a big advantage of LUA is its readability.

Although my suntime.lua is much takes to much memory to be compiled on the watch, the luac compiled version works well.

I am not using a C++ method, because this suntime.lua is tested well and works (despite it is much more precise as anything else, which is tiny enough to fit on the watch).

Works now in the emulator, too

Closing this in favor of #396.
