Hi,
I'd like to use HaskellScript in ASPs (on the severside). I've been unable
to find library files for the objects in asp.dll, or make one myself. Can
anyone help me?
Cheers,
Toby

The paper, 'Domain Specific Embedded Compilers' there is a code snippet :
<%@ Language=HaskellScript %>
<%
module Main where
import Asp
import HtmlWizard
...
%>
I can't find any Asp library files in HaskellScript, Hugs98, HaskellDirect
or Haskell/DB.
I've tried to make my own - (from a previous dicussion):
I've been trying to use HaskellScript in ASPs. Ideally I'd like to have IIS
4.0, with HaskellScript, & HaskellDB.
I've installed may98hugs
HaskellScript (build 11)
HaskellDirect (0.16)
The demo simple.html from HaskellScript works.
I can make a simple testHaskell.asp page like this:
<%@ Language="HaskellScript" %>
<%
main = putStr "Hello, World"
%>
This runs with no errors, but produces no output! I know that HaskellScript
is being used because if I deliberately introduce an error I get the message
:
The problem seems to be that writing to the web server output requires
access to the Response COM object so that you can make calls equivalent to
Response.Write( 'Hello, World' ) in VBScript.
Next I investigated using HaskellScript to produce bindings for the COM
objects used is ASPs. These are in asp.dll.
I've edited the Makefile for examples/comcli to point at the file asp.dll in
\winnt\system32\inetsrv\asp.dll which contains Response and other ASP
objects like Request & Session.
