Ruby equivalent of C# string.Format

Question

I have an array of values and I would like to print it in some format. In C# I would do

string.Format(" {0} | {1} _ {2}!", array[0], array[1], array[2]);

resulting in an output such as

" 10 | 20 _ 30!"

How to achieve this in Ruby?

Is this what you are looking for using String#% ?

array=[11,13,14]
" %s | %s _ %s!" % [array[0],array[1],array[2]]
# => " 11 | 13 _ 14!"
array=[0,13,14]
" %s | %s _ %s!" % array
# => " 0 | 13 _ 14!"

Thank you, also works. Is there a way how to effortlessly print space character when there is a value 0 in the array?

@OndrejJanacek I didn't catch you

Imagine that array[0] stores a value of 0 and I would like to see " | 13 _ 14" instead of " 0 | 13 _ 14"

I accepted your answer because you provided that solution with [*array] which is indeed nice.

@OndrejJanacek [*array] is redundant. It unpacks the array into... another array. Just do % array

In Ruby it should be

" #{array[0]} | #{array[1]} _ #{array[2]}!"
