Ruby: Parsing a string representation of nested arrays into an Array?

Question

Let\'s say I had the string

\"[1,2,[3,4,[5,6]],7]\"

How would I parse that into the array

[1,2,[3,4,[5,6]],7]

Answer 1

The same can be done using Ruby standard libaray YAML as below :

require 'yaml'
s = "[1,2,[3,4,[5,6]],7]"
YAML.load(s)
# => [1, 2, [3, 4, [5, 6]], 7]
