Function parseArgs

internal/codespaces/ssh.go:153–174

parseArgs parses arguments into two distinct slices of flags and command. Parsing stops as soon as a non-flag argument is found assuming the remaining arguments are the command. It returns an error if a unary flag is provided without an argument.

(args []string, unaryFlags string)

// as soon as a non-flag argument is found assuming the remaining arguments are the command.
// It returns an error if a unary flag is provided without an argument.
func parseArgs(args []string, unaryFlags string) (cmdArgs, command []string, err error) {
	for i := 0; i < len(args); i++ {

		// if we've started parsing the command, set it to the rest of the args
		if !strings.HasPrefix(arg, "-") {
			command = args[i:]
			break
		}

		cmdArgs = append(cmdArgs, arg)
		if len(arg) == 2 && strings.Contains(unaryFlags, arg[1:2]) {
			if i++; i == len(args) {
				return nil, nil, fmt.Errorf("flag: %s requires an argument", arg)
			}
