[Haskell-cafe] Getting Haskeline to quit early

[Simon Michael]

Hi Philip,

I'm sorry this answer is not more specific, but perhaps you can get
ideas from hledger's add command, which has that functionality:

Here's the code:

Note that it uses wizards, which sits on top of haskeline and is rather
nice:

Hope it helps,
