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 windows/unix portable 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 such

Errgh. To check against predicate, library HAS to unpack checked

Hello!
I use ghc-7.0.1 and cabal 1.10.0 . When tried to install lhs2tex-1.16 I
got error in Setup.lhs:

Ok, I think, I made it right now. I wrote two versions of the very same
module with roughly the same interface. It is minimalistic framework for
producing, transforming, zipping and folding streaming data (a sample
code that does file IO provided, but it is not well tested yet). One
version abuses
Well, It looks like with 'transformer' look onto iteratees it is
possible to fold two streams without anything except Iteratee, yet some
complications arise. Even real zipping. for example merging two sorted
streams with output stream sorted, is expressible. More preciesely, I
tried to write a sepa
Does haskell 2010 include binary IO? If no, what was the reason?

ell-2010 does not include functional dependencies (wich are
considered evil by many) and, as I recall, type families. This makes mtl
haskell-2010 and haskell-98 uncompilant -(. Functional dependencies and
type familes are tricky things, so it is better to avoid them.

Hi. I Wrote a simple iteration library. It was not intensively tested,
so it MAY contatin bugs, but it is very unlikely. The library is
currently on github: https://github.com/permeakra/iteration
I'm not ready to upload it to hackage, as some testing and extension is
really needed. However, I'd li

The data integrity checks is well-known problem. A common soluting is
use of 'checksums'. Most of them , however, are built in quite
obfuscated manner (like md5) that results in ugly and error-prone

So, the question is: is there a checks

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
ehm. I missed something and ghc api is well documented and stable ?

I still have not found haskell interpreter, that is written in pure

Let us think, that we need some scripting language for our pure haskell
project and configure-compile-run is not a way. In such a case a
reasonably simple, yet standartized and wide known language should be
implemented. What such language may be?
R(4/5/6)RS ?
EcmaScript ?
Some other ?

A Control.Arrow in base package introduces an arrow type, and ghc have
good support for arrow notation. Many things, avaible in monads, are
avaible in arrows as well. There is an arrows package, that introduces
some arrow classes : state, reader, writer and so on. However, it does
not introduce sy
