La version Factory telle que je l'imagine

class Csv
  def self.build_with_header(content, col_sep: ';')
    new(content, col_sep: col_sep, headers: true)
  end

  def self.build_without_header(content, col_sep: ';')
    new(content, col_sep: col_sep, headers: false)
  end

  private

  # A private initializer force the usage of the class factory methods
  def initialize(content, col_sep:, headers:)
    @content = content
    @col_sep = col_sep
    @headers = headers
  end

  def book_metadata
    lines = CSV.new(@content, col_sep: @col_sep, headers: @headers).readlines
    lines.map { |line| line.to_csv(col_sep: @col_sep).strip }
  end
end
