package quotedprintable
import "mime/quotedprintable"
Package quotedprintable implements quoted-printable encoding as specified by RFC 2045.

Examples
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.
Output:Example
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.
Output:Example
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.
