Function ParseFlagsAndArgumentsWithEnv

flagext/parse.go:34–44

ParseFlagsAndArgumentsWithEnv is like [ParseFlagsAndArguments] but also sets flag values from environment variables using [SetFlagsFromEnv]. CLI flags take precedence over environment variables, which take precedence over default values.

(f *flag.FlagSet, prefix string)

// CLI flags take precedence over environment variables, which take precedence
// over default values.
func ParseFlagsAndArgumentsWithEnv(f *flag.FlagSet, prefix string) ([]string, error) {
	if err := f.Parse(os.Args[1:]); err != nil {
		return f.Args(), err
	}

	if err := SetFlagsFromEnv(f, prefix); err != nil {
		return f.Args(), err
	}

	return f.Args(), nil
}

// ParseFlagsWithoutArgumentsWithEnv is like [ParseFlagsWithoutArguments] but also sets
// flag values from environment variables using [SetFlagsFromEnv].
