I’m not sure if it’s good etiquette to post announcements for new orbs here (please let me know if this is the case). I wrote a new orb for automating Leanpub API operations, to automate my book preview/publishing workflow. Thought others who use Leanpub might find it useful.
Orb source (it’s my first orb, feedback appreciated!): https://github.com/zzamboni/leanpub-orb
Blog post describing how I use it: https://zzamboni.org/post/automating-leanpub-book-publishing-with-hammerspoon-and-circleci/
