Functions

func Die

func Die(format string, values ...interface{})

Die is the same as Warn, but it quits with exit status 1 after printing a message.

func MapFilesToDirectories

func MapFilesToDirectories(files, dirs []string) []string

MapFilesToDirectories creates one entry for each file and directory passed. Result is a kind of cross-product. For files f1 and f2 and directories d1 and d2, the returned list will contain d1/f1 d2/f1 d1/f2 d2/f2.

The "files" part might be a bit misleading - you can pass a list of symlinks or directories there as well.

func MustAbs

func MustAbs(dir string) string

MustAbs returns an absolute path. It works like filepath.Abs, but panics if it fails.

func Warn

func Warn(format string, values ...interface{})

Warn is just a shorter version of a formatted printing to stderr. It appends a newline for you.

Types

type StringSliceWrapper

type StringSliceWrapper struct {
	Slice *[]string
}

StringSliceWrapper is an implementation of flag.Value interface. It is basically a proxy that appends strings to an already existing strings slice.

func (*StringSliceWrapper) Set

func (wrapper *StringSliceWrapper) Set(str string) error

func (*StringSliceWrapper) String

func (wrapper *StringSliceWrapper) String() string
