I am writing a cgi-script in Haskell. I am restricted to use only hugs/runhugs.
#!/opt/local/bin/runhugs
module Main where
main = do
putStrLn ("content-type: text/plain\n")
putStrLn ("Hello, Server!")
So far so good. But now I want to get the server's environment variables. For example the "SCRIPT_NAME" environment variable.
With bash I can do:
#!/bin/bash
echo "content-type: text/plain;"
echo ""
echo $SCRIPT_NAME
With the result: /path/to/script.cgi in the browser-window.
For Haskell I found something alike: script <- getEnv "SCRIPT_NAME",
but
#!/opt/local/bin/runhugs
module Main where
main = do
putStrLn ("content-type: text/plain\n")
scriptname <- getEnv "SCRIPT_NAME"
putStrLn scriptname
doesn't work.
Is it possible to do it in a way sort of like that ?
- plain without an import, or
- with an import possible in hugs
