Types ¶

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.

package main

import (
	"fmt"
	"io"
	"mime/quotedprintable"
	"strings"
)

func main() {
	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 := io.ReadAll(quotedprintable.NewReader(strings.NewReader(s)))
		fmt.Printf("%s %v\n", b, err)
	}
}

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.

package main

import (
	"mime/quotedprintable"
	"os"
)

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

}

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.
