What terminal library you will recomedn?
Requirements: crossplatform (win/lin), with direct (i.e. with
line/column number pair) cursor positioning and possybly direct symbol
output. MUST provide function to get terminal dimensions. (could not
find one).
Is there any way to get current position from System.IO.Handle as
Integer? If no, what other b windows/unix portable/b IO function set
of file io with this functionality you can suggest? keeping track of
current position by hand is not an option, sorry.
I'm thinking about c's low-level functions

Ok, I think, I made it right now. I wrote two versions of the very same

producing, transforming, zipping and folding streaming data (a sample
code that does file IO provided, but it is not well tested yet). One

possible to fold two streams without anything except Iteratee, yet some

Most of the time you can get away with usual block ciphers (and even

First question. As I saw in sources, both hxt and haxml uses [Char]'s.
this is very inefficient. I want to know, does any effective parser for
haskell, written in haskell, exists. Efficient means using ByteString to
store strings and possibly building representations that shares one
string for all

There are other ways of adding Haskell as a scripting language -
