Functions ¶
func Parse ¶
func Parse()
Parse parses flags which are set in environment variables using the FLAG_ prefix. That is for a flag named x, x=$FLAG_x if $FLAG_x is set. If the flag is set in the command line, the command line value of the flag takes precedence over the environment variable value. It also calls flag.CommandLine.Parse() to parse flags sent directly as arguments, unless flag.Parse has been previously called.
func ParseFromEnv ¶
func ParseFromEnv()
ParseFromEnv parses flags which are set in environment variables using the FLAG_ prefix. That is for a flag named x, x=$FLAG_x if $FLAG_x is set. If the flag is set in the command line, the command line value of the flag takes precedence over the environment variable value.
