Hi,
the following patch is a proof-of-concept implementation of external
format guessing for incoming messages (and customizable external
formats for outgoing messages, defaulting conservatively to latin-1).
With that patch, cl-irc now opens a binary stream to the server, and
opens flexi-streams on top of that. The outgoing part is pretty
straightforward; the incoming part not so much (:
Reading works like this:
* We read a line of latin-1 chars
* We try to decode their code-chars (latin1 is a 1:1 translation to
code-chars, and where it isn't, I hope flexistreams takes care of
that (-:) using the list of external-formats in
*default-incoming-external-formats*.
* When we find a decoding that doesn't throw a error, we build a
message from that.
Positive side effect: cl-irc should now work on windows because the
external format allows specification of eol convention. Negative side
effect: I didn't get parsing to work without #\Return, so this patch
appends a #\Return character to the raw message.
Which brings me to the todo list:
* DCC connections probably don't work. I don't care about dcc, so I
won't fix them (:
* The parser should work without #\Return.
* reading latin1 and decoding from the char codes is ... ugly. But
it's probably less ugly than doing our own buffering. Maybe
somebody wants to investigate that. (:
Here's the patch:
Cheers,
