Scala a better println

Question

I often find myself doing things like:

println(foo)

when I'd like to do:

println foo

The compiler does not allow this.

Also, println is a mouthful, I really just want to say:

echo foo

So, in a base package object I created the echo version of println:

def echo(x: Any) = Console.println(x)

Easy enough, have echo application wide, great.

Now, how do I invoke echo without needing to wrap the Any to print in parens?

Answer 1

object ∊ {def cho(s: Any) {println(s)}}

∊cho "Hello world"

will save your fingers.

It works because ∊ is a math-symbol in the Unicode Sm set, hence counts as an operator in Scala, so doesn't require spaces when placed next to alphanumeric characters.

You could also

object echo {def -(s: Any) {println(s)}}

echo-"Hello world"

which works pretty well IMO.

YEARS LATER EDIT: another almost-solution, using StringContext:

implicit class PimpMyString(sc: StringContext) {
  def echo(args: Any*) = println(sc.raw(args: _*))
}

echo"Hello World"
