type Reader

type Reader struct {
    // contains filtered or unexported fields
}

Reader is a quoted-printable decoder.

func NewReader

func NewReader(r io.Reader) *Reader

NewReader returns a quoted-printable reader, decoding from r.

Code:

for _, s := range []string{
    `=48=65=6C=6C=6F=2C=20=47=6F=70=68=65=72=73=21`,
    `invalid escape: <b style="font-size: 200%">hello</b>`,
    "Hello, Gophers! This symbol will be unescaped: =3D and this will be written in =\r\none line.",
} {
    b, err := ioutil.ReadAll(quotedprintable.NewReader(strings.NewReader(s)))
    fmt.Printf("%s %v\n", b, err)
}

Output:

Hello, Gophers! <nil>
invalid escape: <b style="font-size: 200%">hello</b> <nil>
Hello, Gophers! This symbol will be unescaped: = and this will be written in one line. <nil>

func Reader.Read

func (r *Reader) Read(p []byte) (n int, err error)

Read reads and decodes quoted-printable data from the underlying reader.

type Writer

type Writer struct {
    // Binary mode treats the writer's input as pure binary and processes end of
    // line bytes as binary data.
    Binary bool
    // contains filtered or unexported fields
}

A Writer is a quoted-printable writer that implements io.WriteCloser.

func NewWriter

func NewWriter(w io.Writer) *Writer

NewWriter returns a new Writer that writes to w.

Code:

w := quotedprintable.NewWriter(os.Stdout)
w.Write([]byte("These symbols will be escaped: = \t"))
w.Close()

Output:

These symbols will be escaped: =3D =09

func Writer.Close

func (w *Writer) Close() error

Close closes the Writer, flushing any unwritten data to the underlying io.Writer, but does not close the underlying io.Writer.

func Writer.Write

func (w *Writer) Write(p []byte) (n int, err error)

Write encodes p using quoted-printable encoding and writes it to the underlying io.Writer. It limits line length to 76 characters. The encoded bytes are not necessarily flushed until the Writer is closed.
