Functions

func Dir

func Dir(useLocal bool, name string) http.FileSystem

Dir returns a http.Filesystem for the embedded assets on a given prefix dir. If useLocal is true, the filesystem's contents are instead used.

func FS

func FS(useLocal bool) http.FileSystem

FS returns a http.Filesystem for the embedded assets. If useLocal is true, the filesystem's contents are instead used.

func FSByte

func FSByte(useLocal bool, name string) ([]byte, error)

FSByte returns the named file from the embedded assets. If useLocal is true, the filesystem's contents are instead used.

func FSMustByte

func FSMustByte(useLocal bool, name string) []byte

FSMustByte is the same as FSByte, but panics if name is not present.

func FSMustString

func FSMustString(useLocal bool, name string) string

FSMustString is the string version of FSMustByte.

func FSString

func FSString(useLocal bool, name string) (string, error)

FSString is the string version of FSByte.

func RegisterHttpPlotter

func RegisterHttpPlotter(b reg.ProcessorRegistry)

func RegisterPlot

func RegisterPlot(b reg.ProcessorRegistry)
