Actions

You can execute actions to play with a context:

val result = Context().execute(listOf(
    SetAction("x", IntegerFactory.instantiate(2)),
    WhileAction(
        Equality(VariableFactory.instantiate("x"), IntegerFactory.instantiate(10), Equality.Operator.LessThan), listOf(
            SetAction("x", Sum(VariableFactory.instantiate("x"), IntegerFactory.instantiate(1)))
    )),
    PrintAction(listOf(StringValue("x = "), VariableFactory.instantiate("x")))
))

result will looks like this:

Context(
    mapOf(
        "x" to IntegerFactory.instantiate(10) // The value of x
    ),
    listOf(
        StringValue("x = "), IntegerFactory.instantiate(10), StringValue("\n") // What we printed
    )
)
