The title says it all. I've seen some issues and PR talking about it but nothing in the README. Or is it a WIP?
WIP :)
There's a fork that does it already but I'm trying to make one that is backward compatible, at least can support 2 and 3.
For others looking for the fork, I think this is it: https://github.com/jdanielian/open-api-rswag
Merged. Version 2.3.0 of rswag supports Openapi 3.0.
Just change your swagger_helper from swagger: 2.0 to openapi: '3.0.1' and it will attempt to output openapi3 with no changes needed to your tests.
You will get deprecation warnings if there's anything that can be made more like openapi 3's syntax, usually done in the swagger_helper.
If anyone notices that it does not generate valid openapi3 on their existing tests please open an issue. Not we know that the common trick of adding example onto the response metadata will result in a validation warning, we will look at that for 2.4.x
Hope this helps!
