I’ve been using hammerspoon for several years and it has really become integral to my workflow.

You may want to check out the extension package spacehammer[0]. It includes a bunch of workflows and shortcuts that I’ve found extremely useful.

Interestingly (for me at least), it’s authored in Fennel [1], a lisp that compiles to lua. I actually found spacehammer originally when I was working on converting my personal hammerspoon config to Fennel.
