Standard methods

A bunch of useful standard methods!

  • print(args...) and println(args...) writes to standard output
  • len() returns length of a measurable element (String, Array or Unit)
  • sleep(millis: Int)
  • rand(from: Int, to: Int): Int
  • int(Char or String or Float) converts into an int type
  • exit(exitCode: Int)
  • float(Int or Char or String): Float
  • bool(String): Bool
  • time(): Int time (in millis) since program started
  • read(): String and readln(): String reads from standard input
  • format(String, Format Args...): String formats a string with values provided, equal to String.format() of Java
  • typeOf(Any Element): Type returns type signature of an element
  • copy(Any Element): Any duplicates the element (primitives only!)
  • memclear() experimental method to clear all the memory space

Useful snippets

Formating a string with args

let name = "Melon"
println( format("Hello %s!", name) )
// prints "Hello Melon!"

format() method is the exact same as String.format()! That's what's called under the hood.

println(typeOf("Melon") == type::String)              // true
println(typeOf(arrayOf(5, 2)) == type::Array<Int>)    // true
