Output results of `mix hex.docs offline` as EPUB instead of HTML

Question

I keep offline copies of the documentation for Hex packages via mix hex.docs offline PACKAGE_NAME. This creates an HTML directory in ~/.hex/docs/hexpm/PACKAGE_NAME/.

I would like to do the same thing, but with the output as EPUB instead of HTML, and ideally, in one step.

How can I download offline EPUBs for documentation of packages hosted on Hex.pm?

Answer 1

As of December 2019, it is currently not possible to do this in one step without using ex_doc directly, but it appears that there are plans to support EPUB generation by default in a future release.
