direg 0.2.6

direg让您维护任意注册表数据（以可以“合并”的Python字典形式存在）。通过少量工作，可以将硬编码的值替换为易于维护和灵活的注册条目。

假设我们有一个文件位于/my/path/registry.py，内容如下。

data = {
    'one.Foo.meth.somevar': 26804,
    'one.Foo.somevar': 24742,
    'one.myfunc.somevar': 16834,
    'one.outer.inner.somevar': 7678,
}

然后在某个模块one中，我们可以执行以下操作

one.py

from direg import get_value, registries
# Load the registry with the above data. Note that this could take place in another module and could include an
# arbitrary number of registry files.
registries.append('/my/path/registry.py')

class Foo:
    somevar = get_value('somevar')  # will be 24742
    def meth(self):
        return get_value('somevar')

f = Foo()
f.meth()  # will return 26804
f.somevar  # 24742
Foo.somevar  # also 24742

def myfunc():
    somevar = get_value('somevar')
    return somevar

myfunc()  # will be 16834
