overdub 0.7

用法

安装：

python -m pip install overdub

使用这些结构：

from overdub import MutableOverdub

a = {'foo': 1, 'bar': {'baz': 2}, 'qux': {'one': 1}}
b = {'foo': 3, 'bar': {'baz': 4}, 'qux': {'two': 2}}

更新：

overdubbed = MutableOverdub(a)
overdubbed.update(b)
assert overdubbed.foo == 3
assert overdubbed.bar.baz == 4
assert overdubbed.qux == {'two': 2}

合并：

overdubbed = MutableOverdub(a)
overdubbed.merge(b)
assert overdubbed.foo == 3
assert overdubbed.bar.baz == 4
assert overdubbed.qux == {'one': 1, 'two': 2}

重新定位：

overdubbed = MutableOverdub(a)
overdubbed.rebase(b)
assert overdubbed.foo == 1
assert overdubbed.bar.baz == 2
assert overdubbed.qux == {'one': 1, 'two': 2}

解除数据绑定：

overdubbed = MutableOverdub(a)
assert isinstance(overdubbed, Overdub)
naked = MutableOverdub(a)
assert not isinstance(naked, Overdub)

冻结配置：

overdubbed = overdubbed.frozen()

yaml文件

它还可以从yaml文件中读取配置，用于此安装：

python -m pip install overdub[yaml]

然后，合并所有文件：

from overdub import yaml

overdubbed = yaml.load_from_file('a.yml', b.yml')
assert overdubbed.foo == 3
assert overdubbed.bar.baz == 4
assert overdubbed.qux == {'one': 1, 'two': 2}
