I've been working on a quick program that acts (vaguely) like a console, lets me type notes and outputs them in a .tex file. I figure it's not that complicated, but it uses a vaguely n-ary structure, so that I can have headers and sub-notes, which loos like:
data Note = N { nTitle :: {Char}, nBody :: {Char}, nFormat :: Format, subs :: [Note]
| E [Char]
Format's just a collection of preset formats, so I don't have to dynamically handle that (since I didn't need to for my uses).
Anyways, for whatever reason, sometimes while adding notes, it sends me an error: Prelude.(!!): index too large
Obviously, sometimes you call list!!index with index > (length list - 1). Are you aware that the indices are 0-based? If it's not that, one would have to analyse the code, but it would be better to see more of it for that.
