## Default Variables

### demo_role_dict

#### Default value

```YAML
demo_role_dict:
  key1:
    sub: some value
```

#### Example usage

```YAML
demo_role_dict:
  key1:
    sub: some value
  key2:
    sublist:
      - subval1
      - subval2
```

### demo_role_empty

#### Default value

```YAML
demo_role_empty: ''
```

### demo_role_empty_dict

... or you can use a valid json. In this case, the json will be automatically prefixed with the annotation key and you can use e.g. `to_nice_yaml` filter in your templates. To get this working, you have to prefix your json with a `$` char.

#### Default value

```YAML
demo_role_empty_dict: {}
```

#### Example usage

```YAML
demo_role_empty_dict:
  key1:
    sub: some value
  key2:
    sublist:
      - subval1
      - subval2
```

### demo_role_other_tags

If a variable need some more explanation, this is a good place to do so.

#### Default value

```YAML
demo_role_other_tags: []
```

#### Example usage

```YAML
demo_role_other_tags:
  - package1
  - package2
```

### demo_role_single

#### Default value

```YAML
demo_role_single: b
```

### demo_role_undefined_var

If you want to add an explicit notice, that a var is not set by default, this is one option. Make sure to flag it as json value: `@var demo_role_undefined_var: $ "_unset_"`

#### Default value

```YAML
demo_role_undefined_var: _unset_
```

### demo_role_unset

You can set values as string, but there is no magic or autoformatting...

#### Default value

```YAML
demo_role_unset:
```

#### Example usage

```YAML
demo_role_unset: some_value
```
