Ian Lynagh wrote a pure haskell readline implementation a while ago,
I think that was Malcolm Wallace.
... and it is part of the readline package! See
System.Console.SimpleLineEditor. Needless to say, it is far from
perfect, but does give some basic facilities. There are lots of ways
it could be extended.
(I haven't checked, but I really hope the cabal mechanisms for
configuring the readline package do not require a working actual-
readline installation, because SimpleLineEditor is explicitly designed
to workaround its absence! It is supposed to provide a uniform
interface regardless of whether readline is there.)
Regards,
Malcolm
