Add whitespace before and after a string in ruby?

Question

I want to add a whitespace before and after random strings.

I have tried using "Random_string".center(1, " ") but it doesnt work.

Thanks

Answer 1

My ruby is rusty, but IMO nothing wrong with the easy way

def pad( random )
    " " + random + " "
end

padded_random_string = pad("random_string")

using center

"random_string".center( "random_string".length + 2 )

Answer 2

irb(main):001:0> x='Random String'
=> "Random String"
irb(main):002:0> y=' '+x+' '
=> " Random String "
irb(main):003:0> x.center(x.length+2)
=> " Random String "

The parameter to center is the total length of the desired output string (including padding).

Answer 3

I mean, is there some reason that you can't just do this?

padded_string = ' ' + random_string + ' '
