Instance Method Details

#format_value(value, opts = {}) ⇒ Object

Create a string representation of the value that is a valid and correct Ruby literal for that value. Please note that the exact representation is not guaranteed to be the same between different platforms and Ruby versions. The guarantee is merely that calling this method with any supported type will produce a string that produces an equal value when it is passed to Kernel::eval

Parameters:

  • value (Hash, Array, String, Symbol, Integer, Float, NilClass) —

    value to format
