save() not working on the micro:bit

If I use espruino 1v86 on my microbit you get this error when calling save:

Erasing Flash...
Writing...
ERROR: Too big to save to flash (244 vs -4 bytes)
Deleting command history and trying again...
Erasing Flash...
Writing...
ERROR: Too big to save to flash (163 vs -4 bytes)

however if I use espruino 1v85 I can save files all day long. for 1v86 i even enabled the minification in the web IDE which said it minifed from 41bytes to 8, this still didnt allow the save in 1v86, only works in 1v85.

EDIT: If i use any form of minification with 1v86 it fails because it changes things like show(1); to ho(1);

Hmm - I'm not sure why the minification does that...

I'll try and look into this next week - the fact it says -4 makes me think that somehow it's got confused about how much flash memory it has available.

Is there a way to show the amount of memory avaliable?

process.memory() - but as far as I know that won't show how much flash is available.

Yeah, I found these commands, it doesn't show flash.

To be honest there's nothing you can really do about it from Espruino itself - it'll need rebuilding...

I downloaded from the "cutting edge" builds espruino_1v86.206_microbit.hex and now it works fine, I can save code and run code on it. I see someone made a fix in github.

Yes, I literally did it about an hour ago. Glad it's fixed for you!

Yep, thanks!
