API

(cyclone quoted-printable)

[procedure] (qp-encode bv start-col max-col separator)

Allow for RFC1522 quoting for headers by always escaping ? and _

[procedure] (quoted-printable-encode-string src . o)

Return a quoted-printable encoded representation of the input according to the official standard as described in RFC2045.

? and _ are always encoded for compatibility with RFC1522 encoding, and soft newlines are inserted as necessary to keep each lines length less than max-col (default 76). The starting column may be overridden with start-col (default 0).

[procedure] (quoted-printable-encode . o)

Variation of the above to read and write to ports.

[procedure] (quoted-printable-encode-bytevector . o)

[procedure] (quoted-printable-encode-header encoding . o)

Return a quoted-printable encoded representation of string as above, wrapped in ... as per RFC1522, split across multiple MIME-header lines as needed to keep each lines length less than max-col. The string is encoded as is, and the encoding enc is just used for the prefix, i.e. you are responsible for ensuring str is already encoded according to enc.

[procedure] (quoted-printable-decode-string src . o)

Return a quoted-printable decoded representation of str. If mime-header? is specified and true, _ will be decoded as as space in accordance with RFC1522. No errors will be raised on invalid input.

[procedure] (quoted-printable-decode-bytevector . o)

[procedure] (quoted-printable-decode . o)

Variation of the above to read and write to ports.

Examples

(import (scheme base) (cyclone quoted-printable) (cyclone test))
(test-group "quoted-printable"

  (test "J'interdis aux marchands de vanter trop leur marchandises. Car ils se font vite pédagogues et t'enseignent comme but ce qui n'est par essence qu'un moyen, et te trompant ainsi sur la route à suivre les voilà bientôt qui te dégradent, car si leur musique est vulgaire ils te fabriquent pour te la vendre une âme vulgaire."
