getenv

README

I needed a cleaner way to get environment variables with default values.

var (
        somevar = getenv.Getenv("TOOL_SOMEVAR", "default_value")
)

One might also have to process many variables with the same prefix

env := getenv.NewEnv("TOOL")
var somevar = env.Getenv("SOMEVAR", "default_value")
