OpenAPI v3

[biow0lf]

Hello,

I want to implement OpenAPI v3 specification support in gem and want to discuss details:

1. I will not remove Swagger v2 specification support.
2. I will add OpenAPI v2 specification support and wrap swagger v2 parts with ifs.
3. I will port swagger_v2_api_declaration.json to openapi v3 and write specs.
4. Add migration guide.

@fotinakis what you think about all this?

@biow0lf that sounds pretty great, sorry I'm don't have tons of time to help guide this but if you wanted to make a PR I could take a look. The more backwards compatible the better, and the more tested the better.

[biow0lf]

@fotinakis I understand. I will try to found time to finish this soon.

I've made a start here: #120

I welcome contributions to the PR :)

Is this still happening? It would be really great.

EDIT:
#120
This would let me think that it is supported, but I don't see anything in the README talking about it

@PhilippeChab From description of the Pull Request the support is basic? I wouldn't be surprised if some important feature in OpenAPI v3 is missing.
