[Haskell-cafe] Cabal Test-suites + custom preprocessors

Hi café, I am successfully using a custom preprocessor to build my main executable. In particular, I am using UUAGC to preprocess .ag files into .hs files. My Setup.hs file uses 'uuagcLibUserHook' from the package uuagc-cabal to do this, which in particular overrides Cabal's 'buildHook' for me. Now I am trying to add a test-suite (of type exitcode-stdio-1.0). I want the test suite to be able to import the modules which implement the main program. Unfortunately, building the test suite fails, because the .ag files don't seem to be built into .hs files. Does anybody know if Cabal actually supports using custom preprocessors for building a test-suite? If so, is 'buildHook' still the right hook to override? Thanks, -- Iain
