[Haskell-cafe] lhs2TeX: automatic line wrap within code blocks?

[David Mihola]

Dominique,

thank you very much for your reply!

Yes, that would work for the code-blocks, but I'd still prefer
automatic line wrapping like in this example:

http://www.bollchen.de/blog/2011/04/good-looking-line-breaks-with-the-listings-package/

Also this does not solve the case of multi line results in eval-statements.

But still, thanks again - and as my deadline draws nearer (this is
homework in a security lecture) I may use your solution and also
decrypt the text first and then copy the decrypted text into the
source file (to get rid of the eval-statement).

David
