Example #2

File: build_install.go Project: patrickToca/go-coreutils

The install flags -- shared with overwrite and remove -- are as follows:
	
	-a, --all           install all utilities
	-d, --dir           install utilities in specific dir (default %s ($GOBIN))
	-o, --overwrite     overwrite current GNU coreutils (if they exist)
	-p, --prefix=S      prefix command with S, e.g., if -p=go-, then
	                    the command file would be named go-wc, go-cat, etc.
		--files-from=F  install files from F (newline delimited)
		--files-from0=F install files from F (null-delimited)

}

var (
	all       = flag.BoolP("all", "a", false, "")
	overwrite = flag.BoolP("overwrite", "o", false, "")
	prefix    = flag.StringP("prefix", "p", "", "")
	dir       = flag.StringP("dir", "d", "", "")

	complicated = *overwrite || *prefix != "" || *dir != ""
)

func installUtils(names []string) {
	if gobin == "" && *dir == "" {
		fmt.Println("go-coreutils: Cannot have empty $GOBIN and empty --dir")
		os.Exit(1)
	}

	if len(names) < 1 {
		fmt.Println("go-coreutils: Must list utilities to install or use --all option")

Example #3

File: main.go Project: EricLagergren/pwpls

  -e, --exclude		exclude specific special characters (default = "")
  -i, --include-special	include special characters (default = random)
  -l, --length		required password length (default = 8)
  -w, --lower		number of lowercase characters (default = random)
  -n, --number		number of passwords to print (default = 1)
  -s, --special		number of special characters (default = 0)
  -u, --uppercase	number of uppercase characters (default = random)
