How do I format a string with string interpolation in Scala as a fixed width string?

Question

I\'m interfacing with a really old system and the file I need to generate needs a field that is a formed from a string but needs to be exactly 15 in width.

I want so

Use String.format with a format string. Surely something there will do what you want :-)

This code would do what you want:

scala> val companyName = "FooBar, Inc"
companyName: String = FooBar, Inc

scala> f"$companyName%15s"
res0: String = "    FooBar, Inc"
