def parse_semver(version)
  return [0, 0, 0] if version.nil?

  v = version.to_s
  v = v.sub(/\Av/, "")
  v = v.split("-", 2).first || ""

  parts = v.split(".")
  return [0, 0, 0] if parts.length != 3

  [Integer(parts[0]), Integer(parts[1]), Integer(parts[2])]
rescue ArgumentError, TypeError
  [0, 0, 0]
end

.semver_less_than?(left_version, right_version) ⇒ Boolean Also known as: semver_less_than
