Is it possible to get Hook working with Leap or Yep from https://ironicsoftware.com?
Thanks for asking, @harets There’s some interesting history here. I used to use that app and even covered it in Cognitive Productivity with macOS: 7 Principles for Getting Smarter with Knowledge. We started looking into Yep compatibility on 2017-10-02 (over a year before the first public beta of Hook which was in January 2019). We found it does not include a selection property in its AppleScript dictionary like other apps, nor anything that software can use to get the selected documents. I contacted Ironic Software in January 2018 making the request. I never heard back. Is that app still maintained? If so I would recommend contacting them per Contacting Developers of Other Apps and Information for Developers – Hook. You could reference this post.
I sent an email message to the developers with the appropriate links.
