Functions

func Copy

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

Copy a file from one location to another

func CopyTemp

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

Copy a file from one location to another using a temp file

func CreateWith

func CreateWith(path string, handler FileHandler) (err error)

Create a file and use it inside a closure. Will automatically close the file after the closure completes and remove the corrupt file if an error is thrown.

func CreateWithTemp

func CreateWithTemp(path string, handler FileHandler) error

Like CreateWith, but will create a temporary file and rename it to the final path once the file has been written successfully. If an error occurs, the temp file will be removed.

func Exists

func Exists(path string) bool

Determine if a path exists or not

func HasPrefix

func HasPrefix(path string, prefix []byte) (bool, error)

Determine if a file starts with a given prefix

func IsDir

func IsDir(path string) bool

Returns true if a path exists and is a directory. It still returns false even if the path doesn't exist.

func OpenFirst

func OpenFirst(paths ...string) (f *os.File, err error)

Open the first existing path in a list of paths

func ReadLines

func ReadLines(f io.Reader) (lines []string, err error)

Read all lines from an open text file into a slice

func ReadLinesFromFile

func ReadLinesFromFile(path string) (lines []string, err error)

Read all lines from a text file into a slice

Types

type FileHandler

type FileHandler = func(f *os.File) error
