How to convert OpenAPIv3 schema to .proto?

[Ark-kun]

I have an OpenAPIv3 schema or JsonSchema.
Can I use gnostic or gnostic-generate to produce equivalent .proto file?

I've just started trying this out... wondering the same thing. I've tried on windows and linux, not seeing a proto file from the json input

gnostic does not yet convert OAS documents into .proto representations. But we have a summer project underway to explore this. Thanks for inquiring about this!

Hello! As part of my GSoC project, I have the privilege to implement this feature under supervision from Tim and Noah. Currently, all the code is maintained here and is in very active development. I'd say that the feature is in a pre-alpha release state and there is probably more that doesn't work than there is that does, but I welcome every kind of contribution (especially issues).

Just to follow up here, @LorenzHW's project is now at https://github.com/googleapis/gnostic-grpc. Thanks @LorenzHW !
