Question

I need my program to create and edit a config file, which would contain information about set of objects, and than read it at every execution. Is there some sort of guideline for config style that i can use?

I’m using C++ on windows.

Answer 1

It largely depends on the language, platform and the scope of your config files. There’s for example the properties files in Java world for configuration, and others already mentioned here such as YAML.

XML is generally frowned upon for configuration, since it’s very verbose. You still find it in many applications, Web frameworks, etc.

I think the best practice would be to choose the right configuration format for the job at hand. You can evaluate and try them for yourself, while considering these pointers:

1. What’s the standard? (e.g. ini files in Windows, properties files in Java)
2. Is there native support in my language, or do I have to roll my own implementation?
3. Can my configuration format easily describe what I want to store as configuration?

I’m sure you could think of other considerations. If you update your question to clarify the scope, you’ll get more useful answers.
