Haskell Interpreter
HEAT uses a Haskell interpreter that you have to install separately. Currently HEAT works only with the Glasgow Haskell Compiler Interpreter (ghci). It has been tested with ghc version 7.0.3. We advise you to install the Haskell Platform, which includes ghci and many libraries that you might want to use as well. HEAT needs to know the full path of the ghci exectuable. The first time you start HEAT, it will ask you for that path. Under the menu item Options you can later change that path and also set further command-line-options and an additional search path for libraries. By default ghci will search for imported modules amongst the installed libraries and the directory of the importing module.
