Hey all. Just thought I'd give an update... Cabal now does something [1] for preprocessors, though it's perhaps not perfect. I need a real test case, a smallish program that uses a preprocessor (except for cpp, which isn't yet supported). Any suggestions? Something that uses happy perhaps? Once I have such an example, and get cpp working nicely, then I'll release 0.2. Here's the cabal web page: http://www.haskell.org/cabal/ You can of course see what I have now by using darcs to check out the repository. On Debian simply: % apt-get install darcs % darcs get http://cvs.haskell.org/darcs/cabal peace, isaac [1] Foo.y is a happy grammer which, when processed, will produce Foo.hs. The description file should include the module Foo. ./setup sdist (source distribution): Include Foo.y, not Foo.hs. Maybe we could add a flag to include Foo.hs as well. This makes sense for some preprocessors and not for others, but I'm wary of including too much preprocessor-specific behavior. ./setup clean: Removes Foo.hs if Foo.y exists. ./setup build: Preprocesses Foo.y to Create Foo.hs before any compilation. The issue with cpp is that we can't go by extensions as we do with the rest of the preprocessors... There is a function in HMake which tests to see if a file needs to be cpp'd, so we can employ that. I think we'll probably have to just treat cpp a little differently from the others, unfortunitely, and I haven't gotten around to it.
