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
