Functions

func Minify

func Minify(m *minify.M, w io.Writer, r io.Reader, params map[string]string) error

Minify minifies CSS data, it reads from r and writes to w.

Example

m := minify.New()
m.AddFunc("text/css", Minify)

if err := m.Minify("text/css", os.Stdout, os.Stdin); err != nil {
	panic(err)
}
