在json和yaml格式之间转换aws cloudformation模板
cfn-flip的Python项目详细描述
AWS云信息模板翻转
关于
aws cloudformation template flip是一个在JSON和YAML格式之间转换AWS CloudFormation模板的工具，尽可能使用yaml格式的短函数语法。
术语“flip”的灵感来自于著名的unix命令行工具flip，它可以在unix、mac和ms-dos格式之间转换文本文件。
安装
可以使用pip安装AWS CloudFormation Template Flip：
pip install cfn_flip
用法
aws cloudformation template flip既是一个命令行工具，也是一个python库。
注意，命令行工具的拼写为带连字符的cfn-flip，而python包的拼写为带下划线的cfn_flip
命令行工具
Usage: cfn-flip [OPTIONS] [INPUT] [OUTPUT]
AWS CloudFormation Template Flip is a tool that converts AWS
CloudFormation templates between JSON and YAML formats, making use of the
YAML format's short function syntax where possible."
Options:
-i, --input [json|yaml] Specify the input format. Overrides -j and -y
flags.
-o, --output [json|yaml] Specify the output format. Overrides -j, -y, and
-n flags.
-j, --json Convert to JSON. Assume the input is YAML.
-y, --yaml Convert to YAML. Assume the input is JSON.
-c, --clean Performs some opinionated cleanup on your
template.
-l, --long Use long-form syntax for functions when converting
to YAML.
-n, --no-flip Perform other operations but do not flip the
output format.
--version Show the version and exit.
--help Show this message and exit.
cfn flip将检测输入模板的格式，并分别将JSON转换为YAML和YAML转换为JSON
示例：
从
stdin读取并输出到stdout：cat examples/test.json | cfn-flip从文件读取并输出到
stdout：cfn-flip examples/test.yaml
从文件读取并输出到另一个文件：
cfn-flip examples/test.json output.yaml
读取文件并清除输出
cfn-flip -c examples/test.json
python包
要从您自己的python项目中使用AWS CloudFormation Template Flip，请根据需要导入函数flip、to_yaml或to_json
