Hi all,
I've just uploaded Clipboard-2.2.0 to Hackage [1].

clipboard. The API is very simple, so anyone can use it without knowing of
low-level Win32 API. Currently, this library only works on a Windows OS, due

Good

Hello, folks!
I have just released HaTeX 3 to Hackage:

It is a first version, not well documented yet, but now you can test it with
a simple cabal install hatex.
What is HaTeX?
HaTeX consists in a set of combinators which allow you to build LaTeX code,

Hello Cafe!
Today I released to Hackage a new version of the HaTeX package (
http://hackage.haskell.org/package/HaTeX-3.1.0 ).
If you don't know HaTeX, it is a combinator library of the LaTeX syntax.

Hello,
A new version (3.2) of HaTeX has been released today to Hackage:

HaTeX is the LaTeX language syntax implementation done in Haskell. Key
changes in this version are:
+ LaTeX parser implemented (so new dependency on parsec).
+ Greek alphabet
Hi Cafe,
today I opened the command prompt and typed cabal install ftphs. Then I
read:

And I started to feel confused. Because I already have installed that

Indeed, it seems to be for parsec:
? ghc-pkg latest bytestring

? ghc-pkg latest parsec

Haskell Platform versions: bytestring-0.9.1.10, parsec-3.1.1.

I have spent some time and, when I unregistered (with ghc-pkg unregister)
all dependencies (even indirect dependencies) I have installed since I have
the Haskell Platform, then the cabal install ftphs worked.
Now I feel I understand the problem, but still seems annoying.
Thanks for the pointer,
Greetings Haskellers!
A new version of HaTeX is ready to use in Hackage:

== Description ==
HaTeX is a heavily maintained LaTeX code parser/generator. Write LaTeX
documents with all the advantages you already have in Haskell (recursion,
type system,
If one parameter is not enough, you always can add more:
Test m a b = Test { f :: m IO a - IO b }
This way, if
run :: m IO a - IO a
then
Test run :: Test m a a
But for other type for your run function
run' :: m IO a - IO b
you get
Test run' :: Test m a b
So you can have different types
This is something I always missed. Thank you!

Hello, Haskell Cafe folks.
My programming life (which has started about 3-4 years ago) has always been
in the functional paradigm. Eventually, I had to program in Pascal and
Prolog for my University (where I learned Haskell). I also did some PHP,
SQL and HTML while building some web sites,
a - m (Seq a)
g = Seq.replicateM
Maybe is just in my test case, where the Int argument is big and the
monadic action short, but it looks to me that Data.Sequence.replicateM can
be faster than it is right now.
Regards,
Daniel Díaz.

Good point. However, I forced the result to evaluate using `deepseq` and I
still got similar results.

f really is a kind of specialization of g.
Could the reason for f performing better be list fusion? Anything
happening inside Control.Monad.replicateM should be subject to it.
