Types
Represents a single article. Please note that except the splitting into header and body no parsing is done.
Article  

Represents a single group.
Group  

data Monad m => NntpT m a Source
NntpT represents a connection. Since some servers have short timeouts it is recommended to keep the connections short.
data Monad m => NntpState m Source
NntpState represents a state at given moment. Please note that this type is not a part of stable API (when we will have one).
data Monad m => NntpConnection m Source
NntpConnection represents a connection in a NntpT monad.
Please note that for runNntpWithConnection
you need to supply both input
and output
functions.
NntpConnection  

Indicates an error of handling NNTP connection. Please note that this should
indicate client errors only (with the exception of ServiceDiscontinued
,
in some cases PostingFailed
and NoSuchCommand
. The last one if propagated
outside NNTP module indicates a bug in library or server.).
NoSuchGroup  Indicates that operation was performed on group that does not exists. 
NoSuchArticle  Indicates that operation was performed on article that does not exists. 
PostingFailed  Indicates that posting operation failed for some reason. 
PostingNotAllowed  Indicates that posting is not allowed. 
ServiceDiscontinued  Indicates that service was discontinued. 
NoSuchCommand  Indicates that command does not exists. 
type NntpParser m a = ParsecT ByteString () (NntpT m) aSource
Functions
runNntpParser :: Monad m => NntpParser m a > NntpT m aSource
Transforms NntpParser into NntpT monad taking care about input position
nntpPutStr :: Monad m => ByteString > NntpT m ()Source
Puts an argument to output.
nntpPutStrLn :: Monad m => ByteString > NntpT m ()Source
Puts an argument to output followed by endofline.
:: Monad m  
=> String  Command. 
> ByteString  Arguments. 
> NntpParser m a  Parser of output. 
> NntpT m a  Returned value from parser. 
Sends a commad.
Try commands one by one to check for existing command.
