Hi Brian,
Sorry for the delayed response.
My goal is to write a program GhcRemake that works like "ghc --make." However, instead of terminating after compilation is done, I want the program to stay open and wait for me to hit <ENTER>. When I hit <ENTER>, GhcRemake rebuilds the project, just as if I had called "ghc --make" again with the same arguments. The benefit of such a program is that GhcRemake should be able to cache a lot of data in memory between invocations and hopefully be able to do the subsequent re-makes much faster.
Nice idea!
BTW, when I get around to addressing #276 http://hackage.haskell.org/trac/ghc/ticket/276 then you'll be able to compile to object code inside GHCi, so to do you what you want above you would just fire up GHCi and type :r to recompile each time. GHCi will cache the interface files between recompilations. Cheers, Simon
