Nice! I used to love AHK to death, incidentally it also got me my first paid programming job.
It‘s about the only software I dearly missed after switching to Mac, but recently I found Hammerspoon and couldn‘t have been happier.
Yep, Lua is a bit weird and exotic, but hey, so is AHK. In the end, you trade in some of AHKs terseness for better modularity and compatibility with existing packages.
