配置文件用HOCON/.conf还是json

简单比较一下两种配置文件的优缺点：

JSON:

• easy to generate programmatically
• well-defined and standard
• bad for human maintenance, with no way to write comments, and no mechanisms to avoid duplication of similar config sections

conf

• nice for humans to read, type, and maintain, with more lenient syntax
• built-in tools to avoid cut-and-paste
• ways to refer to the system environment, such as system properties and environment variables

The idea would be to use JSON if you're writing a script to spit out config, and use HOCON if you're maintaining config by hand. If you're doing both, then mix the two.
