Emile (& Images)
Emile is a library to parse an e-mail address in OCaml. This project is an extraction of mrmime.
This implementation follow some RFCs:
We handle UTF-8 (RFC 6532), domain defined on the SMTP protocol (RFC 5321), and general e-mail address purpose (RFC 822, RFC 2822, RFC 5322) without folding-whitespace.
According RFC 822, an e-mail address into an e-mail can be splitted by a
folding-whitespace. However, this kind of form is not an usual case where user
mostly wants to parse input from a form (for example). At the end, emile is
not able to parse this kind of input:
A Group(Some people)
:Chris Jones <c@(Chris's host.)public.example>,
[email protected],
John <[email protected]> (my dear friend); (the end of the group)"
However, a pre-process (like
unstrctrd) can fold input and give
you an usual output. emile can not be used into an e-mail context without this
kind of pre-process.
Then, for domain part (explained on RFC 5321 - SMTP protocol), we handle this kind of domain (IPv4 and IPv6 domain) with ipaddr:
first.last@[12.34.56.78]
first.last@[IPv6:1111:2222:3333::4444:12.34.56.78]
It's possible to notify multiple domains for one local-part like this:
<@a.com,b.com:[email protected]>
It's a valid form according RFC 882.
Even if we don't handle the folding-whitespace, we are able to discard comments.
a(a(b(c)d(e(f))g)h(i)j)@iana.org
If you think it's easy to parse an e-mail address, you should look tests.
