Swagger v2 to v3 conversion

[eclipse1985]

In the README is stated that openapi2 package supports

OpenAPI 2 files, including serialization, deserialization, and validation

But I can't find a way to read a swagger v2 file.

I need to convert a swagger v2 file to swagger v3. Is that possible in any way with kin-openapi ?

I have a similar requirement. @eclipse1985 were you able to achieve this? :)

Unfortunately no

@eclipse1985 @dinusha92 - assuming you have read your v2 spec as []byte, you can use a function like this to convert to v3:

func V2ToV3(v2Data []byte) ([]byte, error) {
	v2Spec := &openapi2.Swagger{}
	if err := json.Unmarshal(v2Data, v2Spec); err != nil {
		return nil, err
	}

	v3Spec, err := openapi2conv.ToV3Swagger(v2Spec)
	if err != nil {
		return nil, err
	}

	return json.Marshal(v3Spec)
}

Yes, I just tried, and you are right. We can close this issue.

Could this be a CLI command?
