Thanks. Haskell is incredibly neat ;-)

Hi,
Now that I have read the tutorials, I think that the best way to learn
Haskell would be to use the language and write something simple yet
useful. I noticed that Haskell lacks a module for reading/writing csv
(comma separated value) files, so I thought I could implement that.
Questions:

Hi Tamas,
Questions:
1. Please tell me if you know of a csv module, because then I would do
something else.
I think MissingH contains a simple CSV parser, but the server seems to be
down.
2. I am looking for a parser, but I don't know Haskell parsers. Is
Parsec a good choice?

Now I need to find something else for practice.
How about writing a CiteULike plugin? For example, what could be
really useful is if somebody wrote one for the French open archive
HAL. This will give you a nice chance to play maybe with parsing
stuff, or one of the HTML/XML libraries, or

Parsec is definitely a good choice, but beware that it parses the whole
input before returning, thus it may consume a huge batch of memory. As
CSV is a line oriented format, you should make your
