Functions

func Copy

func Copy(from, to string) (err error)

Copy copies the file content from source to destination. Tries hard to succeed on various systems by temporarily tweaking directory permissions and removing the destination file when necessary.

func ExpandTilde

func ExpandTilde(path string) (string, error)

func GetLans

func GetLans() ([]*net.IPNet, error)

func HideConsole

func HideConsole()

func HideFile

func HideFile(path string) error

func InWritableDir

func InWritableDir(fn func(string) error, path string) error

InWritableDir calls fn(path), while making sure that the directory containing `path` is writable for the duration of the call.

func NativeFilename

func NativeFilename(s string) string

func NormalizedFilename

func NormalizedFilename(s string) string

func Rename

func Rename(from, to string) error

Rename moves a temporary file to it's final place. Will make sure to delete the from file if the operation fails, so use only for situations like committing a temp file to it's final location. Tries hard to succeed on various systems by temporarily tweaking directory permissions and removing the destination file when necessary.

func ShowFile

func ShowFile(path string) error

func TryRename

func TryRename(from, to string) error

TryRename renames a file, leaving source file intact in case of failure. Tries hard to succeed on various systems by temporarily tweaking directory permissions and removing the destination file when necessary.

Types

type ReplacingWriter

type ReplacingWriter struct {
	Writer io.Writer
	From   byte
	To     []byte
}

func (ReplacingWriter) Write

func (w ReplacingWriter) Write(bs []byte) (int, error)
