Note: This is only a very rough sketch of a full RFC-822 parser; in particular the tokenizing of addresses does not adhere to all the quoting rules. Note: RFC 2822 is a long awaited update to RFC 822. This module should conform to RFC 2822, and is thus mis-named (it's not worth renaming it). Some effort at RFC 2822 updates have been made, but a thorough audit has not been performed. Consider any RFC 2822 non-conformance to be a bug. RFC 2822: http://www.faqs.org/rfcs/rfc2822.html RFC 822 : http://www.faqs.org/rfcs/rfc822.html (obsolete) Directions for use: To create a Message object: first open a file, e.g.: fp = open(file, 'r') You can use any other legal way of getting an open file object, e.g. use sys.stdin or call os.popen(). Then pass the open file object to the Message() constructor: m = Message(fp) This class can work with any input object that supports a readline method. If the input object has seek and tell capability, the rewindbody method will work; also illegal lines will be pushed back onto the input stream. If the input object lacks seek but has an `unread' method that can push back a line of input, Message will use that to push back illegal lines. Thus this class can be used to parse messages coming from a buffered stream. The optional `seekable' argument is provided as a workaround for certain stdio libraries in which tell() discards buffered data before discovering that the lseek() system call doesn't work. For maximum portability, you should set the seekable argument to zero to prevent that initial \code{tell} when passing in an unseekable object such as a a file object created from a socket object. If it is 1 on entry -- which it is by default -- the tell() method of the open file object is called once; if this raises an exception, seekable is reset to 0. For other nonzero values of seekable, this test is not made. To get the text of a particular header there are several methods: str = m.getheader(name) str = m.getrawheader(name) where name is the name of the header, e.g. 'Subject'. The difference is that getheader() strips the leading and trailing whitespace, while getrawheader() doesn't. Both functions retain embedded whitespace (including newlines) exactly as they are specified in the header, and leave the case of the text unchanged. For addresses and address lists there are functions realname, mailaddress = m.getaddr(name) list = m.getaddrlist(name) where the latter returns a list of (realname, mailaddr) tuples. There is also a method time = m.getdate(name) which parses a Date-like field and returns a time-compatible tuple, i.e. a tuple such as returned by time.localtime() or accepted by time.mktime(). See the class definition for lower level access methods. There are also some utility functions here.

Read header lines up to the entirely blank line that terminates them. The (normally blank) line that ends the headers is skipped, but not included in the returned list. If a non-header line ends the headers, (which is an error), an attempt is made to backspace over it; it is never included in the returned list. The variable self.status is set to the empty string if all went well, otherwise it is an error message. The variable self.headers is a completely uninterpreted list of lines contained in the header (so printing them will reproduce the header exactly as it appears in the file). t i t unreadi s EOF in headerss From s s s No headerss% Non-header line where header expecteds ; bad seekN( R t dictt unixfromt headerst listt statust headerseent firstlineR t startoflineR R t hasattrR R R t readlinet linet startswitht appendt stript xt iscommentt islastt isheadert lenR ( R R R R R R# R R R ( ( R R x sf ! c C s6 | i d } | d j o | | i Sn d Sd S( s Determine whether a given line is a legal header.
