Instance Method Details

#parse_to_array(string) ⇒ Array<String>

Parse a string into the (nearly) equivalent Ruby array. This only handles arrays with string members (double-, or single-quoted), and does not support the full quite of escape sequences that Ruby allows in double-quoted strings.

Parameters:

  • The (String) —

    string to be parsed.

Returns:

  • (Array<String>) —

    The parsed array elements, including handling any escape sequences.
