Open sourcing code without including specific set-up values in source [closed]

Question

I am creating a few small experiments / examples which I am open sourcing on git hub.

How have people dealt with user specific config/set-up vars in the past?

I would ideally like to commit the exact same code that I myself am using, but without including my URL's or app id / secrets etc.

I have thought that perhaps I could do it in one of the following ways, but is there a standard or recommended way of doing this?

baseURL = include myConfig.txt;

or

baseURL = "Enter Your URL Here";

Answer 1

You could have the very simplest config options as environment variables.

You could have a small config object, which holds dummy values.

You could add a config.ini.sample file.
