hello, for the project I am doing, I would like to be able to create two documentation sets: - the user documentation, done with normal Setup.hs --haddock and - the developer documentation, where all modules are exposed and haddock is run with --ignore-all-exports What is the right way to do this? I see two options, but both are somewhat clumsy: 1. Write a custom Setup.hs, using the Cabal library. Ideally, it would accept a new command, like "Setup.hs --haddock-devel". However Cabal doesn't seem to be designed for adding new commands or options to them - the interface is hardcoded. For instance, I can't add a command in such a way that it would be listed alongside others when calling "Setup.hs --help". 2. Call haddock from a makefile. This is a one-liner with haddock 0.8, but not with haddock 2.0 and above. The problem is that haddock 2.0 only supports --read-interface and doesn't support --use-package any more. Thus I have to find all the haddock interfaces by hand, for instance by calling ghc-pkg for each library I depend on. This is of course straightforward, but I feel that it shouldn't be my job. Any comments or ideas? Cheers, Misha
