Returns a list of (decoded_string, charset) pairs containing each of the decoded parts of the header. Charset is None for non-encoded parts of the header, otherwise a lower-case string containing the name of the character set specified in the encoded string.

Optional s is the initial header value. If None, the initial header value is not set. You can later append to the header with .append() method calls. s may be a byte string or a Unicode string, but see the .append() documentation for semantics. Optional charset serves two purposes: it has the same meaning as the charset argument to the .append() method. It also sets the default character set for all subsequent .append() calls that omit the charset argument. If charset is not provided in the constructor, the us-ascii charset is used both as s's initial charset and as the default for subsequent .append() calls. The maximum line length can be specified explicit via maxlinelen. For splitting the first line to a shorter value (to account for the field header which isn't included in s, e.g. `Subject') pass in the name of the field in header_name. The default maxlinelen is 76. continuation_ws must be RFC 2822 compliant folding whitespace (usually either a space or a hard tab) which will be prepended to continuation lines. errors is passed through to the .append() call. s i N( R R t USASCIIR* R+ t selft _charsetR& t _continuation_wst lent replacet SPACE8t cws_expanded_lent _chunksR R t errorsR$ t MAXLINELENR% t _firstlinelent _maxlinelen( R/ R R R$ R% R& R7 R5 ( ( R" t __init__‚ s" c C s | i ƒ S( s A synonym for self.encode().N( R/ t encode( R/ ( ( R" t __str__· s c C s¹ g } d } x | i D]’ \ } } | } | oW | d j o( | d j o | i t ƒ d } q‚ q† | d j o | i t ƒ q† n | } | i t | t | ƒ ƒ ƒ q Wt i | ƒ S( s) Helper for the built-in unicode function.s us-asciiN( Ns us-ascii( Ns us-ascii( Ns us-ascii( t uchunksR t lastcsR/ R6 R R t nextcsR t USPACEt unicodeR t UEMPTYSTRINGt join( R/ R R> R R@ R?

Optional charset, if given, should be a Charset instance or the name of a character set (which will be converted to a Charset instance). A value of None (the default) means that the charset given in the constructor is used. s may be a byte string or a Unicode string. If it is a byte string (i.e. isinstance(s, str) is true), then charset is the encoding of that byte string, and a UnicodeError will be raised if the string cannot be decoded with that charset. If s is a Unicode string, then charset is a hint specifying the character set of the characters in the string. In this case, when producing an RFC 2822 compliant header using RFC 2047 rules, the Unicode string will be encoded using the following charsets in order: us-ascii, the charset hint, utf-8. The first character set not to provoke a UnicodeError is used. Optional `errors' is passed as the third argument to any unicode() or ustr.encode() call. t 8bits us-asciiN( R R R/ R0 R* R+ R R t input_codect incodecRB R7 t ustrt output_codect outcodecR< R. t UTF8t UnicodeErrorR6 R ( R/ R R R7 RL RN RK ( ( R" R Ú s, c C sA | i | ƒ } | i | t ƒ } | i | ƒ } | | j o | | f g Sn | d j o | | f g Sn‰ | d j o | i | | | | ƒ Snb | t | ƒ j o6 | } | i | | t ƒ } | i | | t ƒ } n t | | | ƒ \ } } | i | ƒ } | i | t ƒ } | | f g } | | i | | | i | ƒ S( NRI s us-ascii( R t to_splittableR t splittablet from_splittablet TrueR t encoded_header_lent elenR$ R/ t _split_asciit splitcharsR2 t splitpntt Falset firstt lastt _binsplitt fsplittablet fencodedt chunkt _splitR: ( R/ R R R$ RX R\ RR R^ R_ RV RY R R` R[ ( ( R" Ra s$ c C s8 t | | | i | i | ƒ } t | | g t | ƒ ƒ S( N( RW R t firstlenR/ R: R1 RX t chunkst zipR R2 ( R/ R R Rb RX Rc ( ( R" RW ? s c C s¹ g } x– | D]Ž \ } } | p q n | d j p | i d j o | } n | i | ƒ } | o | d i d ƒ o d } n d } t | | | | ƒ q Wt | i } | i | ƒ S( NiÿÿÿÿR R ( Rc t newchunksR R R t header_encodingR t header_encodet endswitht extrat _max_appendR$ t NLR/ R1 t joinerRD ( R/ Re R$ Ri R R R Rc Rl ( ( R" t _encode_chunksD s s ;, c C s¨ g } | i } d } x€ | i D]u \ } } | | d } | | i d ƒ j o | } n | | i | | | | ƒ 7} | d \ } } | i | ƒ } q W| i | | ƒ S( s‡ Encode a message header into an RFC-compliant format. There are many issues involved in converting a given string for use in an email header. Only certain character sets are readable in most email clients, and as header strings can only contain a subset of 7-bit ASCII, care must be taken to properly convert and encode (with Base64 or quoted-printable) header strings. In addition, there is a 75-character length limit on any given encoded header field, so line-wrapping must be performed, even with double-byte character sets. This method will do its best to convert the string to the correct character set used in email, and encode and line wrap it safely with the appropriate scheme for that character set. If the given charset is not known or an error occurs during conversion, this function will return the header untouched. Optional splitchars is a string containing characters to split long ASCII lines on, in rough support of RFC 2822's `highest level syntactic breaks'. This doesn't affect RFC 2047 encoded lines. i i R iÿÿÿÿN( Re R/ R9 R$ t lastlenR6 R R t targetlenRU Ra RX t lastchunkt lastcharsetRm ( R/ RX R$ Rp Rq R Re R Ro Rn ( ( R" R< g s ( t __name__t __module__R R; R= RE RG RH R Ra RW Rm R< ( ( ( R" R' s 5 7 . #c C s g } | } x}| i ƒ D]o} | i ƒ } t | ƒ | j o | i | ƒ | } q n x6 | D] } | | j o Pq_ q_ W| i | ƒ | } q t i d | ƒ } | d j o | } n d } | d } t | ƒ } t | i d t ƒ ƒ } g } d } xi| i | ƒ D]X} | t d t | ƒ d ƒ | } t | ƒ } | } | d j oI | oB t | ƒ d j o/ t i | d ƒ o | i | ƒ | | 7} q | | | j o | o | i | i | ƒ | ƒ n | | j oG | d j o: t! | | | | d ƒ } | i# | d ƒ | d g } n | g } | t | d ƒ } | } q | i | ƒ | | 7} q W| o | i | i | ƒ ƒ q q W| S( Ns %s\s*s ;,R R s i i iÿÿÿÿ($ t linesRb t maxlenR R R t lstripR2 R t restlenRX t cht ret compilet cret eolRl t joinlenR& R3 R4 t wslent thist linelenR t partt maxt curlent partlent onfirstlinet fcret matchRD RW t sublt extend( R Rb Rw R& RX Rx Rˆ R~ R} R€ R R R Rt R| Ru R„ R{ Rl R… Rƒ ( ( R" RW sb ! ; c C sµ d } t | ƒ } xj | | j o\ | | d d ?} | i | | t ƒ } | i | ƒ } | | j o | } q | d } q W| i | | t ƒ } | i | | t ƒ } | | f S( Ni i ( t iR2 RR t jt mR RS RT R` RU t chunklenR$ RZ R[ R\ ( RR R R$ RŠ R` RŒ R‹ R R\ R[ ( ( R" R] Õ s ( t __doc__Ry R t email.quopriMIMER t email.base64MIMEt email.ErrorsR! t email.CharsetR+ Rk R RA R4 RC R8 R.
