Hi!
My students have the task to program an interactive chatbot. We have run into a problem that I can't solve either:
When we read the user's input through
t <- getLine it is not possible to delete typos before hitting enter and thereby sending the input off to the system (at least in OS X, bash). I didn't find that terribly problematic, but of course it is a bit of a show stopper from their point of view.
Is it possible that you need to tweak the input buffering settings? http://haskell.org/ghc/docs/latest/html/libraries/base/System-IO.html#v:hSet... You probably want to look at 'interact' also. Or just switch to readline as others have suggested. Jason
