The `Readline' interface

(Darren Moffat supplied the `Readline' interface.) The `Readline' module is a straightforward interface to the GNU Readline library. As such, you will need to look at the GNU documentation (and have a `libreadline.a' file around somewhere...) You'll need to link any Readlining program with `-lreadline -ltermcap', besides the usual `-syslib ghc' (and `-fhaskell-1.3'). The main function you'll use is:
readline :: String{-the prompt-} -> IO String
If you want to mess around with Full Readline G(l)ory, we also provide:
rlInitialize, addHistory,

rlBindKey, rlAddDefun, RlCallbackFunction(..),

rlGetLineBuffer, rlSetLineBuffer, rlGetPoint, rlSetPoint, rlGetEnd,
rlSetEnd, rlGetMark, rlSetMark, rlSetDone, rlPendingInput,

rlPrompt, rlTerminalName, rlSetReadlineName, rlGetReadlineName
(All those names are just Haskellised versions of what you will see in the GNU readline documentation.)
