Hi,
Suppose I have some kind of analysis tool that I want to run on a Cabal project.
The analysis tool only deals with Haskell files, so I need Cabal to generate Haskell files from CPP-enabled Haskell files, .hsc files, alex and happy files etc.
I see two possible ways to do that: use Cabal as a library, or my tool to be run by Cabal as a compiler.
I think that the path of least resistance is to make your analysis tool command-line compatible with ghc. Then you can use it like this: $ cabal configure --with-compiler=/path/to/my-ghc $ cabal build Since 'cabal build' usually just calls 'ghc --make Main.hs', you'll need to do dependency chasing, but this can be implemented by parsing the output of 'ghc -M'. -- () ascii ribbon campaign - against html e-mail /\ www.asciiribbon.org - against proprietary attachments
