I love that it’s a command line tool — I’ll try it soon.

I use OpenIn for this [1] (it’s paid, but a one-time purchase at a very reasonable price). It works with URLs too, supports “browser profiles”, and lets you create logic using JavaScript (e.g., do X if the filename contains Y, or do Z if a modifier key is pressed).

It works really well and even has the ability to “fix” what external apps have changed. I plan to use this on new Macs to reconstruct my app associations and rules.

I do wish the rules were defined in plain text files — sometimes it’s hard to follow the logic through the UI and the way it handles things.

Another comment mentions Hammerspoon (which I used in the past — it was very nice). Maybe I can rebuild part of my current setup with it.

I loveee hammerspoon. And had a subscription to OpenIn a bit back. Advanced scripting isn’t going to happen, even paging out to another script. Recently committed to Regex which would cover most of that. I’ll look into how it “fixes” old associations.
