Usage

Writing specs

require "open_api"

OpenAPI.build do |api|
  doc = api.document(
    openapi: "3.0.1"
    info: {
      title: "Catlib",
      version: "0.1"
    },
    paths: {
      "/meow" => api.path_item(
        get: {
          tags: ["cats"],
          request_body: {
            ref: "#/components/schemas/cat"
          }
        }
      )
    },
    components: {
      schemas: {
        :cat => api.schema(
          type: "object",
          description: "A cat"
        )
      }
    }
  )

  puts doc.to_json
)

Parsing specs

require "open_api"

File.open("openapi.yml") do |file|
  doc = OpenAPI.from_yaml(file)
  puts doc.to_json
end
