Golang NewFlagSet Examples

Example #1

File: cli.go Project: beginnor/docker

func (cli *DockerCli) Subcmd(name, signature, description string) *flag.FlagSet {
	flags := flag.NewFlagSet(name, flag.ContinueOnError)
	flags.Usage = func() {
		fmt.Fprintf(cli.err, "\nUsage: docker %s %s\n\n%s\n\n", name, signature, description)
		flags.PrintDefaults()
		os.Exit(2)
	}
	return flags
}

Example #2

File: parse.go Project: beginnor/docker

//FIXME Only used in tests
func Parse(args []string, sysInfo *sysinfo.SysInfo) (*Config, *HostConfig, *flag.FlagSet, error) {
	cmd := flag.NewFlagSet("run", flag.ContinueOnError)
	cmd.SetOutput(ioutil.Discard)
	cmd.Usage = nil
	return parseRun(cmd, args, sysInfo)
}
