eval() function in Kotlin

  • 772

Is there a way to evaluate a String in Kotlin like JavaScript's eval()?

For example:

var str = "var x = 5"
eval(str)

println(x) //Y que muestre por pantalla 5

    What you are looking for is called scripting and this is supported since version 1.1 using the javax.script. Here an example of its use :

    val engine = ScriptEngineManager().getEngineByExtension("kts")!!
engine.eval("val x = 3")
println(engine.eval("x + 2"))  // Prints out 5

    There is also a project on github with examples of how to use the API available.
