enhancedyaml v0.1.1

增强的pyyaml

它使pyyaml更加方便，并且避免了重复的yaml数据。

功能如下：

• 按deafult，使用类的名称作为yamlobject的yaml_标记
• 将锚加载为yamlobject实例的属性
• 将yamlobject实例的属性anchor转储为anchor&；name

sudo pip install enhancedyaml

# examples/enhanced_data.yaml

%YAML 1.1
---
examples:
    - !Example &first
        data: I am the first one.
    - !Example &second
        data: I am the second one.
order:
    - \*first
    - \*second

创建一个yamlobject而不指定yaml标签

import enhancedyaml

class Example(enhancedyaml.YAMLObject): pass

加载的yaml

代码：

from pprint import pprint

data = enhancedyaml.load(open('data/enhanced_data.yaml'))
pprint(data)

输出：

{'examples': [<__main__.Example object at 0x7fa825fb4fd0>,

              <__main__.Example object at 0x7fa825fb4cd0>],
 'order': [<__main__.Example object at 0x7fa825fb4fd0>,
           <__main__.Example object at 0x7fa825fb4cd0>]}

数据的内容['order']

代码：

pprint(list(example.__dict__ for example in data['order']))

输出：

[{'anchor': u'first', 'data': 'I am the first one.'},
 {'anchor': u'second', 'data': 'I am the second one.'}]

示例具有addnational属性锚。

再次转储数据

代码：

print enhancedyaml.dump(data, default_flow_style=False)

输出：

examples:
- &first !Example
  data: I am the first one.
- &second !Example
  data: I am the second one.
order:
- \*first
- \*second

它几乎和原来的山药一样。

转储运行时生成的对象

代码：

e1 = Example()
e2 = Example()
e1.data = "I don't have `anchor`."
e2.data = "I don't have `anchor`, too."
es = [e1, e2, e2, e1]
print enhancedyaml.dump(es, default_flow_style=False)

输出：

- &example002 !Example
  data: I don't have `anchor`.
- &example001 !Example
  data: I don't have `anchor`, too.
- \*example001
- \*example002

您可以在enhancedyaml/examples目录中找到更多示例。

玩得开心！
