I'd like to hear more about people using Arrows-minus-arr, as I ran into the same in a project I'm working on for interactive construction of GUI-wrapped functional values & code. - Conal -----Original Message----- From: haskell-cafe-bounces@haskell.org [mailto:haskell-cafe-bounces@haskell.org] On Behalf Of Jeremy Shaw Sent: Wednesday, June 01, 2005 10:55 AM To: John Goerzen Cc: haskell-cafe@haskell.org Subject: Re: [Haskell-cafe] CGI module almost useless Hello, I have done all of those things in WASH. But, don't let that stop you from writing something better :) I think some people started a project to write a CGI interface based on a 'Category' -- where a 'Category' is like an 'Arrow' without the 'pure/arr' function...

The Network.CGI module in fptools (and GHC) is not very useful. I
good think
that it should be removed or re-tooled. Here are the main problems with it:
1. It does not permit custom generation of output headers. Thus the CGI script cannot do things like set cookies, manage HTTP auth, etc.
2. It does not permit generation of anything other than text/html documents. Many CGI scripts are used to manage other types of documents. Notably this makes it incompatible with serving up even basic things like stylesheets and JPEGs.
3. It does not permit the use of any custom design to serve up HTML, forcing *everything* to go through Text.Html. This makes it impossible to do things like serving up HTML files from disk.
4. There is documentation in the code, but it is as comments only, and doesn't show up in the Haddock-generated GHC library reference. (Should be an easy fix)
5. It does not appear to support file uploads in any sane fashion
Is there a better CGI module out there somewhere that I'm missing, or should I just set about writing my own?
