Hi,
As a weekend hack, I just realized that Haskell has this wonderful
DoRec syntax that among other things seems to be able to let the user
express context-free grammars together with their processing rules in
normal Haskell code, without template Haskell or anything like that,
just like parser

For parsers, there is also a LALR(1) generator -

Good point.. Just noticed that I managed to misspell Don Stewart's

Hello,
What's the current best practice to build shared objects / dlls to
call Haskell from C? I think I figured out the basics, but I would
like to understand the picture completely and document the current
state of affairs in the Haskell wiki. In particular, I'd like to make

If you want to make Haskell more widely used, do pick a name for
Haskell Prime that starts with an A. I first heard of Haskell when
exploring the list of computer languages that Gedit could highlight.
Just imagine going through all those A,B,C,D,E,F,G before I came to
Haskell.

Hi Arnaud,
Here's a simple counter program. I mount this to /ws/ with mod_scgi,
and can then do requests http://localhost/ws/ or

Thank you for your reply. I benchmarked HDBC.ODBC with MySQL and it is
indeed working well. So whatever slow results I used to get were due
to that particular setup. It looks that HDBC will suit my needs as
well.
Thanks,

What's more, HDBC has a stronger and more versatile API than
Hello,
SCGI module from Hackage is not working for me with Apache mod_scgi, I
think because it uses LazyBytestring to hGetContents on a socket
handle and the Apache side does not close the socket. Also, looking at
the source I didn't see any fork* calls, so I assume it is not doing
concurrency.
Hello,
I had some difficulty building hsql and hsql-mysql (native driver)
packages under GHC 8.3 on Fedora 9. Namely, they do not install with
cabal install, because of a few API changes. Is this considered all
right as GHC 8.3 is still experimental, or should the packages be
updated? If so, can
