# YAML语法基础

## 文件开始符

```
---
```

## 数组List

```yaml
- element1
- element2
- element3
```

数组中的每个元素都是以 - 开始的。

## 字典(Hash or Directory)

```
key: value
```

key和value已冒号加空格分隔。

## 复杂的字典

字典的嵌套

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

字典和数组的嵌套

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

## 注意的地方

变量里有：要加引号

```
foo: "somebody said I should put a colon here: so I did"
```

变量的引用要加引号

```
foo: "{{ variable }}"
```
