Hi Chris,
Where is this functionality provided by Nix?
simply run these commands
# Haskell Platform 2009.2.0.2
nix-env -p ~/ghc-6.10.4 -iA haskellPackages_ghc6104.haskellPlatform

Hello,
I recently tried to install the latest version of pandoc on my debian
stable box (with ghc 6.12.1) using virthualenv as sandboxing
mechanism. But instead of a normal installation, compilation of the
json package (more specifically the Text.JSON.Parsec module) hangs and
causes ghc to

Hi,
it works very well!
I tried to implement it. Here is my test code. Apparently I need some casts
to search the list.
The syntax looks good. Only addEvent will be on the interface, so that
should be fine. If I understand well, that's this function that enforces
the right types to be used. The

It just bothers me a little that I'm not able to enumerate the events, and
also that the user is able to create events with wrong types (like New ::

Am I doing something wrong here?
Well, you're using ghc-6.12 ... :-)
The most recent version of pandoc that Hackage claims to have built with
ghc 6.12 looks to be 1.6. Rolling back that far eliminates the json
dependency entirely, so I think it would solve your issue. Or you could use

Hi Chris,
I cannot see how it can address any of the user-level Haskell package
database management and sandboxing mechanisms that I mentioned in the
announcement and subsequent emails.
have you ever actually used Nix?
Take care,

To be honest I did try to use Nix for exactly this purpose. For some reason
things started to break and since I couldnt find any documentation on how
to do stuff with it, I just abandonded the idea. Also tried out NixOS:
pretty much the same story. Everything appears to be fine at the start, but
Hi Chris,

of course, I didn't mean to imply that you were. My question was phrased
poorly, I am sorry.
What I meant to ask is: how much time, approximately, did you spend
working with Nix? 1 hour? 10 hours? 10 days? 10 months?
Now all packages, including those without exposed modules, are
included. Also, I've attempted to parse the author lists into JSON
arrays. Due to the free format of many fields in the .cabal package
descriptions, including author list, there are many exceptional cases
where they are ill-parsed, but
I made some modifications based on your suggestions (see below).
I made a two parameters class:
*class (Typeable e, Typeable d) = Handled e d *
Because after all what I want is to associate an event with its type
parameters.
I don't know why I cannot implement you suggestion to restrict the

You know that it is not 10 months, but I do object to your line of questioning.
I have invested a considerable good-faith effort into getting to the
bottom of what

I'm having issues with HDBC when connecting to a remote MySQL server -
