PingSwaggerDocument does not take any arguments.

[abhsrivastava]

I am using Finatra on Scala 2.12 and I wanted to use Swagger.

I found this tutorial which is written for a previous library for swagger and finatra integration
https://medium.com/from-the-couch/writing-an-http-service-in-finatra-14239e9f3882

I am trying to modify the code of this tutorial to your library. Towards this I wrote the following code

build.sbt

val versions = new {
  val finatra = "18.3.0"
  val logback = "1.2.3"
  val scalatest = "3.0.5"
  val swagger = "1.0.5"
}
val p = (project in file(".")).settings(
  name := "finatra-tut",
  organization := "com.abhi",
  scalaVersion := "2.12.5",
  libraryDependencies ++= Seq(
    "com.twitter" %% "finatra-http" % versions.finatra,
    "ch.qos.logback" % "logback-classic" % versions.logback,
    "org.scalatest" %% "scalatest" % versions.scalatest,
    "io.paradoxical" %% "finatra-swagger" % versions.swagger
  )
)

PingSwaggerDocument.scala

package com.abhi
import io.swagger.models.{Info, Swagger}
object PingSwaggerDocument extends Swagger

PingController.scala

package com.abhi
import com.twitter.finagle.http.Request
import com.twitter.finatra.http.Controller
import com.twitter.util.Future
import io.paradoxical.finatra.swagger.{SwaggerSupport}

class PingController extends Controller with SwaggerSupport {
  implicit protected val swagger = PingSwaggerDocument  
  get("/ping", swagger { o => 
    o.summary("This is GET PING request")
    .tag("ping")
    .responseWith[Pong](200, "The Pong Message")
  }) { request: Request => 
    info("ping")
    val p = Pong("Result from GET /ping")
    Future.value(p)
  }
}

ExampleServer.scala

package com.abhi

import com.twitter.finagle.http.{Response, Request}
import com.twitter.finatra.http.HttpServer
import com.twitter.finatra.http.filters.{CommonFilters, LoggingMDCFilter, TraceIdMDCFilter}
import com.twitter.finatra.http.routing.HttpRouter
import io.paradoxical.finatra.swagger.SwaggerController
import io.swagger.models.Info

class ExampleServer extends HttpServer {

  PingSwaggerDocument.info(new Info()
      .description("Ping as a service")
      .version("0.0.1")
      .title("Pinged Piper")
  )
  
  override def defaultFinatraHttpPort = ":9999"
  override def configureHttp(router: HttpRouter) = {
    router
      .filter[LoggingMDCFilter[Request, Response]]
      .filter[TraceIdMDCFilter[Request, Response]]
      .filter[CommonFilters]
      .add(new SwaggerController(swagger = PingSwaggerDocument))
      .add[PingController]
  }
}

Models.scala

package com.abhi
case class Pong(message: String)

But this code doesn't compile. it gets an error

[error] /Users/abhsrivastava/IdeaProjects/finatra-tut/src/main/scala/com/abhi/PingController.scala:10:24: com.abhi.PingSwaggerDocument.type does not take parameters
[error] get("/ping", swagger { o =>
[error] ^
[error] one error found
[error] (Compile / compileIncremental) Compilation failed

What changes can I make here so that I can compile my code with your library. this will allow me to use Scala 2.12 along with Finatra and Swagger. the older library does not support Scala 2.12.
