Simple Ruby script to create asciidoc format from a yaml/json openapi 3.0 file
Usage: ruby openapi2asciidoc myapis.yaml > myapis.adoc
This is a script I hacked together in an afternoon, so I have zero guarantees. But it seems to work well enough for the example from https://editor.swagger.io/.
Use https://asciidoctor.org/ to convert the asciidoc file into html or pdf.
