func LookupEnvWithFile

func LookupEnvWithFile(key string) (string, error)

LookupEnvWithFile retrieves the value of the environment variable named by the key (e.g. HCLOUD_TOKEN). If the previous environment variable is not set, it retrieves the content of the file located by a second environment variable named by the key + '_FILE' (.e.g HCLOUD_TOKEN_FILE).

For both cases, the returned value may be empty.

The value from the environment takes precedence over the value from the file.
