(time for a proper email client to be written in Haskell! ;-) )
I had the same thought yesterday, after an Emacs-Lisp session in which
I was trying to get Gnus to do exactly what I wanted it to...
Out of curiosity, how much work would it take to write an easily
configurable, decent MUA in Haskell? I don't know too much about MUAs,
but I have a feeling that we already have quite a few libraries that
are needed for the job: UIs (including HTML rendering...), plugins,
various protocols, encryption...
I'm afraid I don't know much about MUAs either.
I see there's some stuff in Network.* that may be useful...
Unfortunately I don't have time at the moment to try implementing one, but
for what it's worth here are some thoughts I had on what an "ideal" email
client, suitable for Haskell programmers, would be like:
1) Plain text based to avoid problems with viruses etc getting in via HTML.
HTML emails received could just be displayed as plain text (including all
markup)
2) "What-you-see-is-exactly-what-will-be-sent" for editing, so that when you
press "send" you don't need to worry about the text being all mangled up by
wrapping/replacement of characters etc
3) When you click "reply" or "reply all", the original text should be
indented with '>' (at the moment OE requires QuoteFix to achieve this
trivial but essential functionality)
4) An API could be exposed then the user could write scripts to put things
into correct folders etc.
The API could provide info about what is currently waiting on the server,
and the ability to download or delete without downloading (eg for big
attachments that are suspected of being viruses)
5) Ideally the scripting language would be Haskell. There is already stuff
in Language.Haskell.* for doing parsing but I can't find anything which
would allow you to compile and load functions into a running program.
So I'd imagine that the email client would contain a plain text editor that
wrapped text as it is edited (if wrapping is needed nowadays anyway?) with
email addresses and URLs in the text clickable; a tree of folders and a
folder contents window which could display the emails by date/subject/name/
or thread; and an API and way of loading scripts written in Haskell to do
all the complicated automatic stuff - which would now be completely under
the user's control.
Regards, Brian.
