Really precise parsing of email messages requires implementing the RFC822 (more precisely RFC2822 nowadays), which is not a trivial task. I started to do it but gave up due to the absence of a scanf facility. I launched a thread to implement scanf, and 5 years after I understood how to do it in the Caml system! Now that we have scanf, I could go on to implement RFC(2)822. But don't hold your breath: if you don't need a full parser for mail messages the simpler way is to write a (false but trivial) approximation with a lexer... There may be such a program into Xaviers's spamoracle ?

L'analyse syntaxique précise des messages électroniques nécessite l'implémentation de la RFC822 (plus précisément la RFC2822 maintenant), ce qui n'est pas trivial. J'ai essayé une fois mais j'ai arrêté à cause de l'absence d'une fonction scanf. J'ai alors lancé une sous-tâche: implémenter scanf, et 5 ans après j'ai enfin compris comment le faire en Caml! Maintenant que nous avons scanf, je devrais revenir d'interruption et me remettre à implémenter la RFC(2)822. Mais n'attendez pas une distribution rapide: si vous n'avez pas besoin d'un analyseur très précis le plus simple est d'en écrire une approximation (fausse mais triviale) à l'aide d'un lexeur... Il y a sans doute un tel programme dans le filtre spamoracle de Xavier...

Well, O'caml programming is so much fun that everybody wants to reinvent the wheel. I really understand that, I'm also tempted every day. My wheel came into the world in the spring of 2000, and has grown since that a lot. It is now called "ocamlnet" after the fusion with Patrick Doane's wheel, and includes not only a parser for RFC(2)822 messages, but supports also the MIME RFCs (2045-47), RFC 2231, parsing of dates, the ability to parse from pipelines chunk by chunk, and last but not least even printers for these (partly brain-dead) formats. You also find an HTML parser, and a lot of other useful stuff. It is now more a mobile construction set than a wheel. By the way: if anybody has something to contribute, any addition that is useful, works, and will be maintained is still accepted.

It is now called "ocamlnet" after the fusion BTW, ocamlnet IMO is lacking documentation. All .mli are really well commented but there is no out-of-band documentation like the really goog pxp manual or examples for the various ocamlnet modules. Are you planning to write something like that? TIA, Cheers. -- Stefano Zacchiroli - undergraduate student of CS @ Univ.

Yes, a manual is really needed. I have currently not enough time to do it. Maybe I find time for certain special themes... I could imagine an introduction to netchannels with some references to examples would already do most of the job.

Yes this would surely be good, but I'm also thinking about an introduction to the CGI module with some examples. This can be helpful in improving ocaml visibility on the server side scripting world.
