rfc822 / date parser, ocamllex

[Julian Assange]

Does anyone know of an O'caml rfc822 address parser?

`mmm', the O'caml web-browser has a simple date lexer, although its
not rfc822 compliant.

The ocamllex documentation doesn't mention any method of specifying
start conditions. While I can see several different way of gaining
this functionality using sub-lexers and grouping, is this the most
elegant approach?

Cheers,
Julian.

My netstring package contains some useful functions for RFC 822 message
parsing, especially a configurable scanner. However, concrete parsers are
missing.

See http://www.ocaml-programming.de/packages/documentation/netstring/.

Hi Julian,

I've started work on a library to implement internet protocols. One of the
modules has a lexer for mail headers as well as parsers for addresses and
dates. 

The address parser supports all of rfc822 and also includes updates that
have been in later documents.

Also included are modules which implement client-side POP3 and SMTP. You
can get this from:

Thanks patrick, that's perfect.

I'll let you know if I have any additions.

Cheers,
