使用yaml的分层配置
himl的Python项目详细描述
HIML
在python中使用yaml的分层配置。
最新版本为：0.2.1
说明
一个python模块，允许您使用yaml语法合并分层配置文件。它提供深度合并、变量插值和秘密管理器的秘密检索。
如果您希望以避免重复的方式构建层次结构，则这是理想的选择。您可以使用层次结构（如environment/project/cluster/app）定义配置的结构。你想在这个层次结构中使用什么层取决于你。该工具将从根（默认值为）开始读取所有yaml文件，一直到叶（最具体的值为，优先）。
这个想法来自木偶的神像。

This will merge simple/default.yaml with simple/production/env.yaml

The example also showcases deep merging of lists and maps.

Based on the configuration tree from the examples/complex文件夹，上述命令的输出如下：
cluster:
description: 'This is cluster: cluster2. It is using c3.2xlarge instance type.'
name: cluster2
node_type: c3.2xlarge
region:
location: us-east-1
env: dev
“示例”文件夹的外观如下：

Features
Interpolation
In order to avoid repetition, we wanted to make it possible to define a value once and reuse it in other parts of the yaml config. Unlike yaml anchors, these interpolations work across multiple files.

Deep merge
It's possible to have the same key (eg. a dict/list) in multiple files and combine them using a deep merge. See an example here。
