I think, though I haven't tried this, that you can replace the
instHooks with one that:
1. filters out the private executables from the PackageDescription
2. Provides this new PackageDescription to the standard instHook.
Which I would think is the instHook of the UserHooks parameter passed
to your modifed instHook.
Something like (psuedo-code typed in email):
main = defaultMainWithHooks $ defaultUserHooks { instHook = filteredInstHook }
filteredInstHook :: PackageDescription -> LocalBuildInfo -> UserHooks
-> InstallFlags -> IO ()
filteredInstHook package lbi user_hooks install_flags = do
let package' = package { executables = filter_private_executable
(executables package) }
instHook user_hooks package' lbi user_hooks install_flags
Though that last line may need to read:
instHook defaultUserHooks package' lbi user_hooks install_flags

Hi,
I would like to include a few source files as 'executable' sections in a .cabal package description. However, although I do want to use main=mainDefault features, I do not want those packages to be installed when I run 'Setup.hs install'.
Is it possible to do that? I believe there's no flag that indicates install step, since (I guess) flags are checked only at configure time.
Thanks for your help, Maurício
