A clock you write. The program below is parsed into a syntax tree and re-run every frame.
let makes a local; assigning to
text, sub, color, background,
size or spin drives the display. # starts a comment.
h m s ms
h12 ampm t (seconds since midnight)
day month year dow
dayname monthname pi tau
pad base pick round
floor abs min max clamp
lerp sin cos sqrt hsl
rgb upper lower str len
slice repeat
+ - * / %, == != < <= > >=,
and or not, and cond ? a : b. There are no loops and no way to
define a function, so every program is guaranteed to finish.
