Eval

====

Eval evaluates Scala 3 code.

Example Usage

=============

In your `build.sbt` type this or similar:

```scala

ThisBuild / scalaVersion := "3.3.1"

libraryDependencies += ("com.eed3si9n.eval" % "eval" % "0.3.0").cross(CrossVersion.full)

Compile / fork := true

```

In your `Main.scala` type this or similar:

```scala

package example

import com.eed3si9n.eval.Eval

case class ServerConfig(port: Int)

@main def main(): Unit =

  val x = Eval[ServerConfig](

    "example.ServerConfig(port = 8080)")

  println(x.port)

```

Run in `sbt` like so:

```

sbt:eval> run

[info] compiling 1 Scala source to target/scala-3.3.1/classes ...

[info] running (fork) example.main

[info] 8080

```

This shows that the string example.ServerConfig(port = 8080) was evaluated as a Scala code, 

and became available to the main function as an instantiated case class.
