Functions

func ContainsGuesser

func ContainsGuesser(mimeType string, contains [][]byte) func(filename string, data []byte) string

ContainsGuesser returns a guesser function that will check if the data contains any of the given byte slices

If it does, it will return the given mimetype

func ExtensionGuesser

func ExtensionGuesser(m map[string]string) func(filename string, data []byte) string

ExtensionGuesser returns a guesser function that will check if the filename ends with the given extension. If it does, it will return the given mimetype.

This function takes a map of extensions to mimetypes

func Guess

func Guess(filename string, data []byte) string

Guess returns the mime type of the given data

Otherwise return "application/octet-stream"

func LocalDatabaseGuesser

func LocalDatabaseGuesser(filename string, data []byte) string

Check for signatures of known mimetypes in the data

func PlaintextGuesser

func PlaintextGuesser(filename string, data []byte) string

PlaintextGuesser returns a guesser function that will check if the data is ascii or unicode

If it is ascii, it will return "text/plain; charset=utf-8"

If it is unicode, it will return "text/plain; charset=utf-16"

func With

func With(guesser ...GuesserFunc)

With registers a new guesser function

Types

type Guesser

type Guesser struct {
	Funcs []GuesserFunc
}

func New

func New() *Guesser

func (*Guesser) Guess

func (g *Guesser) Guess(filename string, data []byte) string

Guess returns the mime type of the given data

Otherwise return "application/octet-stream"

func (*Guesser) With

func (g *Guesser) With(guesser ...GuesserFunc)

type GuesserFunc

type GuesserFunc func(filename string, data []byte) string
