#reduce(width, ellipses = '...') ⇒ Object

call-seq:

reduce( width, ellipses = '...' )    #=> string

Reduce the size of the current string to the given width by removing characters from the middle of the string and replacing them with ellipses. If the width is greater than the length of the string, the string is returned unchanged. If the width is less than the length of the ellipses, then the ellipses are returned.

Raises:

  • (ArgumentError)
