Read from multiple sources about cleanenv HOT 5 CLOSED

@vlaabra that's already possible. Just read from any sources you want, just keep in mind that the last read may override the previous one if there is a common field in both sources.

from cleanenv.

Thanks!
Could you give an example of the logic you're asking about?

from cleanenv.

cleanenv.ReadConfig("config.yml", &cfg)
cleanenv.ReadConfig("db/conf.yml", &cfg)

🤷‍♂️

from cleanenv.

Say, you have a two config files, cfg_1.yml:

one: 1

and cfg_2.yml:

two: 2

Then the following code

	type config struct {
		One int `yaml:"one"`
		Two int `yaml:"two"`
	}

	cfg := config{}
	cleanenv.ReadConfig("cfg_1.yml", &cfg)
	cleanenv.ReadConfig("cfg_2.yml", &cfg)
	fmt.Printf("%+v", cfg)

will output

{One:1 Two:2}

Sure if there would be one: 123 in the second file, it would rewrite the value from the first one.

Simple enough and no side-effects 😎

So, since we've figured out that it's already been implemented, I'm closing the issue.
