ρ: A DSL for building HTTP services with http4s

val httpService = new RhoService[IO] {
   GET / "hello" / 'world +? param[Int]("fav") |>> { (world: String, fav: Int) => 
     Ok(s"Received $fav, $world") 
   }
}

See the tutorial, wiki and the tests for more examples.

The primary goal of ρ is to provide an easy to use AST with which to build HTTP services which can be inspected to extract a variety of information including:

• Swagger documentation
• HAL documentation

Rho artifacts are available at Maven Central and snapshots are available from the Sonatype repositories.

Stability

ρ remains a work in progress. However, it is now approaching a point where things are beginning to stabilize. Going forward changes to the api should will come more slowly and have deprecation period.
