2019-07-28email: Decode MIME entities without headers.Arun Isaac
* email/email.scm (email->headers+body): If there are no headers, return "" as headers not an eof-object. (parse-email-body): Parse headers of parent entity or email to parse-mime-entity.

2019-07-28email: Support email with mixed encoding of characters.Arun Isaac
Prior to this, parse-email would accept email in the form of a string. A string is constrained to use the same encoding for all its characters whereas an email can have characters encoded using different encoding schemes. Therefore, it is more correct that parse-email deals with bytevectors instead of strings. * email/utils.scm (read-bytes-till): New function. * email/email.scm (body->mime-entities, email->headers+body, decode-body): Deal with emails as bytevectors instead of strings. (parse-mime-entity): Rename text argument to bv. (parse-email, parse-email-body): Overload to handle input in the form of a string or bytevector. * doc/guile-email.texi (Parsing e-mail): Document overloading of parse-email and parse-email-body. * tests/email.scm ("handle truncated multipart message gracefully"): Deal in bytevectors instead of strings. ("email with 8 bit encoding and non UTF-8 charset", "multipart email with a 8 bit encoding and non UTF-8 charset part"): New tests. * tests/email-with-8bit-encoding-and-non-utf8-charset, tests/multipart-email-with-a-8bit-encoding-and-non-utf8-charset-part: New files. Reported-by: Jack Hill <jackhill@jackhill.us>
