Variables

var DirExists = pathutil.DirExists

Alias functions from pathutil as a convenience

var Exists = pathutil.Exists

var ExpandUser = pathutil.ExpandUser

var FileExists = pathutil.FileExists

var IsAppendable = pathutil.IsAppendable

var IsCharDevice = pathutil.IsCharDevice

var IsDevice = pathutil.IsDevice

var IsExclusive = pathutil.IsExclusive

var IsNamedPipe = pathutil.IsNamedPipe

var IsNonemptyDir = pathutil.IsNonemptyDir

var IsNonemptyExecutableFile = pathutil.IsNonemptyExecutableFile

var IsNonemptyFile = pathutil.IsNonemptyFile

var IsReadable = pathutil.IsReadable

var IsSetgid = pathutil.IsSetgid

var IsSetuid = pathutil.IsSetuid

var IsSocket = pathutil.IsSocket

var IsSticky = pathutil.IsSticky

var IsSymlink = pathutil.IsSymlink

var IsWritable = pathutil.IsWritable

var LinkExists = pathutil.LinkExists

Functions

func AddMimeTypeFile

func AddMimeTypeFile(filename string)

func GetMimeType

func GetMimeType(filenameOrReader interface{}, fallback ...string) string

GetMimeType goes out of its way to really, really try to figure out the MIME type of a given filename or io.Reader. If the first argument satisfies the io.Seeker interface, the seeker will Seek() back to the beginning. If it satisfies the io.Closer interface, it will be closed.

func InitMime

func InitMime()

func IsTerminal

func IsTerminal() bool

func MustReadAll

func MustReadAll(filename string) []byte

func MustReadAllString

func MustReadAllString(filename string) string

func MustWriteFile

func MustWriteFile(reader io.Reader, filename string) int64

Same as WriteFile, but will panic if the file cannot be written.

func ReadAll

func ReadAll(filename string) ([]byte, error)

func ReadAllLines

func ReadAllLines(filename string) ([]string, error)

func ReadAllString

func ReadAllString(filename string) (string, error)

func ReadFirstLine

func ReadFirstLine(filename string) (string, error)

func WriteFile

func WriteFile(reader io.Reader, filename string) (int64, error)

Write the contents of the given reader to the specified filename. Filename paths containing tilde (~) will automatically expand to the current user's home directory, and all intermediate parent directories will be automatically created. Will return the number of bytes written, or an error.

Types

type RewriteFileSystem

type RewriteFileSystem struct {
	FileSystem http.FileSystem
	Find       *regexp.Regexp
	Replace    string
	MustMatch  bool
}

func (RewriteFileSystem) Open

func (self RewriteFileSystem) Open(name string) (http.File, error)
