YAML語法

YAML語法是ansible劇本的表達方式。

• 全部YAML均可以選擇以--—開始和...結束
• 列表的全部成員都是以「-」開頭的相同縮進級別的行(一個破折號和一個空格):

---
# A list of tasty fruits
- Apple
- Orange
- Strawberry
- Mango
...

• 字典以簡單的形式表示（冒號後面必須有一個空格）

# An employee record
martin:
    name: Martin D'vloper
    job: Developer
    skill: Elite

• 更爲複雜的數據結構

# Employee records
-  martin:
    name: Martin D'vloper
    job: Developer
    skills:
      - python
      - perl
      - pascal
-  tabitha:
    name: Tabitha Bitumen
    job: Developer
    skills:
      - lisp
      - fortran
      - erlang

也能夠用縮寫形式：

---
martin: {name: Martin D'vloper, job: Developer, skill: Elite}
['Apple', 'Orange', 'Strawberry', 'Mango']

• 值可使用|或>跨多行。使用「文字塊標量」|跨越多行將包括新行和任何尾隨空格。使用「摺疊塊標量」>將新行摺疊到空格;它被用來使本來很長的一行更容易閱讀和編輯。

include_newlines: |
            exactly as you see
            will appear these three
            lines of poetry

fold_newlines: >
            this is really a
            single line of text
            despite appearances
