YAML-シーケンススタイル

To understand sequence styles, it is important to understand collections. The concept of collections and sequence styles work in parallel. The collection in YAML is represented with proper sequence styles. If you want to refer proper sequencing of tags, always refer to collections. Collections in YAML are indexed by sequential integers starting with zero as represented in arrays. The focus of sequence styles begins with collections.

例

宇宙の惑星の数を、コレクションとして作成できるシーケンスとして考えてみましょう。 次のコードは、宇宙の惑星のシーケンススタイルを表現する方法を示しています-

# Ordered sequence of nodes in YAML STRUCTURE
Block style: !!seq
- Mercury   # Rotates - no light/dark sides.
- Venus     # Deadliest. Aptly named.
- Earth     # Mostly dirt.
- Mars      # Seems empty.
- Jupiter   # The king.
- Saturn    # Pretty.
- Uranus    # Where the sun hardly shines.
- Neptune   # Boring. No rings.
- Pluto     # You call this a planet?
Flow style: !!seq [ Mercury, Venus, Earth, Mars,      # Rocks
                    Jupiter, Saturn, Uranus, Neptune, # Gas
                    Pluto ]                           # Overrated

次に、JSON形式の順序付きシーケンスの次の出力を見ることができます-

{
   "Flow style": [
      "Mercury",
      "Venus",
      "Earth",
      "Mars",
      "Jupiter",
      "Saturn",
      "Uranus",
      "Neptune",
      "Pluto"
   ],

   "Block style": [
      "Mercury",
      "Venus",
      "Earth",
      "Mars",
      "Jupiter",
      "Saturn",
      "Uranus",
      "Neptune",
      "Pluto"
   ]
}
