Path Parameters

Path parameters can be extracted from the Path(segments: Seq[String]) argument.

Create a file path_params.sc and paste this code into it:

    //> using scala "3.4.2"
//> using dep ba.sake::sharaf:0.8.0

import io.undertow.Undertow
import ba.sake.sharaf.*, routing.*

val routes = Routes:
  case GET() -> Path("string", x) =>
    Response.withBody(s"string = ${x}")

  case GET() -> Path("int", param[Int](x)) =>
    Response.withBody(s"int = ${x}")

Undertow.builder
  .addHttpListener(8181, "localhost")
  .setHandler(SharafHandler(routes))
  .build
  .start()

println(s"Server started at http://localhost:8181")

Then run it like this:

scala-cli path_params.sc 

Now go to http://localhost:8181/string/abc and you will get the param returned: string = abc.

When you go to http://localhost:8181/int/123,
Sharaf will try to extract an Int from the path parameter.
If it doesn't match, it will fall through, try the next route.
