Functions

func CopyAllContent

func CopyAllContent(srcDir string, dstDir string) error

CopyAllContent copies all files from srcDir to dstDir recursively. Only files' name and content are guaranteed to be the same. Only files are copied, (empty) directories are ignored. Any existing files will be overridden.

func CopyContent

func CopyContent(src string, dst string) error

CopyContent copies the file src to dst. Only the file's name and content are guaranteed to be the same. The parents will be created if they don't exist. The existing file will be overridden.

func Exists

func Exists(path string) (bool, error)

Exists checks if the file or directory exists. If Exists cannot determinate whether the file or directory exists (e.g., permission error), it returns an error.

func ListAll

func ListAll(dirPath string) ([]string, error)

ListAll lists all files and directories under the directory dirPath.

func ListAllFiles

func ListAllFiles(dirPath string) ([]string, error)

ListAllFiles lists all files under the directory dirPath.

func Lowercase

func Lowercase(path string) error

Lowercase renames the file or directory to lowercase. If the file or directory is already lower-cased, it does nothing.

func LowercaseAll

func LowercaseAll(dirPath string) error

LowercaseAll renames the directory to lowercase recursively. If a file or directory is already lower-cased, LowercaseAll does nothing to it.

func MkFile

func MkFile(filePath string) (*os.File, error)

MkFile creates a file and its parents with respectively mode 0666 and 0755 (both before unmask). If the parents of the file already exist, MkFile does nothing. If the file already exist, MkFile truncates it.

func MkFileFromBytes

func MkFileFromBytes(filePath string, b []byte) error

MkFileFromBytes calls MkFile and then writes the content of the bytes to the file.

func MkFileFromReader

func MkFileFromReader(filePath string, r io.Reader) error

MkFileFromReader calls MkFile and then writes the content of the reader to the file.

Note that it's the caller's responsibility to close the reader.

func MkParents

func MkParents(filePath string) error

MkParents creates all parents of a file with mode 0755 (before unmask). If the parents of the file already exist, MkParents does nothing.

func MoveAllContent

func MoveAllContent(srcDir string, dstDir string) error

MoveAllContent moves all files from srcDir to dstDir recursively. Only files' name and content are guaranteed to be the same. Only files are moved, (empty) directories are ignored. Any existing files will be overridden.

Use MoveAllContent to prevent os.Rename to panic "invalid cross-device link".

func MoveContent

func MoveContent(src string, dst string) error

MoveContent moves the file src to dst. Only the file's name and content are guaranteed to be the same. The parents will be created if they don't exist. The existing file will be overridden.
