NAME

Catmandu::Fix::format - replace the value with a formatted (sprintf-like) version

SYNOPSIS

   # e.g. number: 41
   format(number,"%-10.10d") # number => "0000000041"

   # e.g. numbers: 
   #         - 41
   #         - 15
   format(number,"%-10.10d %-5.5d") # numbers => "0000000041 00015"

   # e.g. hash:
   #        name: Albert
   format(name,"%-10s: %s") # hash: "name      : Albert"

   # e.g. array:
   #         - 1
   format(array,"%d %d %d") # Fails! The array contains only one value, but you request 3 values 

   # Test first if the array contains 3 values
   if exists(array.2)
     format(array,"%d %d %d")
   end
