hey guys !
Iīm pretty nu to haskell, and i got the following things to do:
code a client in python that sends string ->done
code a server in haskell that recieves string -> to do...
i initialized the server, set up a socket on port 9900,
so the socket is allready open...
First i read the string with hGetLine:
loop socket =
do
(handle, host, port) <- accept socket
forkIO (client handle)
loop socket
client handle = do
query <- hGetLine handle
this worked pretty good.
Now my Tutor said, I should code this whole thing with hGetChar
instead of hGetLine...
I ainīt got the clue of an clue how to manage this...
I worked something out like:
client handle = do
query <- hGetChar handle
if query = [] then return(0)
else
let list = list ++ query
I donīt know where the string is stored in the handle,
and how to read it out...I mean, I canīt use stuff like
query handle <- hGetChar(firstfrom:query handle)...
Please Help Me !!!
