Hi Michael, Thank you for your reply. I managed to find a solution by myself, which I have added as an answer to my question on Stack Overflow [1]. wizards looks (look?) very interesting, though. I may change to using that instead of Haskeline now! Regards, Philip [1] http://stackoverflow.com/a/29195676/4108393 On Mon, Mar 23, 2015, at 06:48 AM, Simon Michael wrote:
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, -Simon
