14 Quoted-Printable: Encoding and Decoding

 (require net/qp) package: net-lib
The net/qp library provides utilities for quoted-printable (mime-standard) encoding and decoding from RFC 2045 section 6.7.
The library was written by Francisco Solsona.

14.1 Functions

procedure

(qp-encode bstr)  bytes?

  bstr : bytes?
Consumes a byte string and returns its quoted printable representation as a new string. The encoded string uses #"\r\n" where necessary to create shorter lines.

procedure

(qp-decode bstr)  bytes?

  bstr : bytes?
Consumes a byte string and returns its un-quoted printable representation as a new string. Non-soft line breaks are preserved in whatever form they exist (CR, LR, or CRLF) in the input string.

procedure

(qp-encode-stream in out [newline-bstr])  void?

  in : input-port?
  out : output-port?
  newline-bstr : bytes? = #"\n"
Reads characters from in and writes the quoted printable encoded result to out.

The newline-bstr argument is used for soft line-breaks (after =). Note that the default newline-bstr is just #"\n", not #"\r\n".

Other line breaks are preserved in whatever form they exist (CR, LR, or CRLF) in the input stream.

procedure

(qp-decode-stream in out)  void?

  in : input-port?
  out : output-port?
Reads characters from in and writes de-quoted-printable result to out. Non-soft line breaks are preserved in whatever form they exist (CR, LR, or CRLF) in the input stream.

14.2 Exceptions

struct

(struct qp-error ()
    #:extra-constructor-name make-qp-error)

struct

(struct qp-wrong-input qp-error ()
    #:extra-constructor-name make-qp-wrong-input)

struct

(struct qp-wrong-line-size qp-error ()
    #:extra-constructor-name make-qp-wrong-line-size)
None of these are used anymore, but the bindings are preserved for backward compatibility.

14.3 Quoted-Printable Unit

[email protected] and qp^ are deprecated. They exist for backward-compatibility and will likely be removed in the future. New code should use the net/qp module.

 (require net/qp-unit) package: compatibility-lib

value

[email protected] : unit?

Imports nothing, exports qp^.

14.4 -Printable Signature

 (require net/qp-sig) package: compatibility-lib

signature

qp^ : signature

Includes everything exported by the net/qp module.
