Re: [9fans] rc break

[erik quanstrom <quanstro@quanstro.net>]

well, td knows more than i, but doesn't this code look ugly without the
benefit of a break statement?

fn parseargs { endarg = '' {
	while(! ~ $#argv 0){
		switch($argv(1)^$endarg){
		case -r
			earf r usage
		case -f
			earf f usage
		case *
			endarg = y
			cmd = ($cmd $argv(1))
			Shift argv
		}
	}
}}

wouldn't this be better

fn parseargs {
	while(! ~ $#argv 0){
		switch($argv(1)){
		case -r
			earf r usage
		case -f
			earf f usage
		case *
			break;
		}
	}
	cmd = $argv;
}
