Feature, implement :main command
by Neil Mitchell 10 Jan '06

Hi, Attached is a patch that adds a :main command to hugs. :main arguments is equivalent to arguments `withArgs` main, but easier to use because you don't need to import anything extra, and the arguments are parsed as if they were arguments - i.e. :main my test "of this", instead of ["my","test","of this"] `withArgs` main. Since i don't know a whole lot about this area of the compiler, and it is changing the user interface for everyone, I thought it best that someone checks its at least sane before i do anything with it. Thanks Neil

That is, the Cabal library handles > it for --hugs, but assumes the compilers will handle it themselves. The GHC version allows a list of the extensions from Language.Haskell.Extension to be given: {-# LANGUAGE CPP, ForeignFunctionInterface, MultiParamTypeClasses #-} I'm not sure the commas are a good idea, but it's written this way in the Cabal documentation. It's not too late to change this. Cheers, Simon

C preprocessor + WinHugs
by Neil Mitchell 31 Oct '05

31 Oct '05

Hi, I'm looking into implementing C preprocessing in WinHugs. I've looked around and bundling a copy of cpphs seems like the best solution, since few windows users will have a cpp hanging around somewhere that can be found. I've hacked together a basic implementation, the only thing is that its a lot slower, mainly because its being run on every single file which is completely unneeded. Is there some way to detect if a hs file requires preprocessing? If not, its almost going to be better to stick with no preprocessing, and have a faster development environment. The ways I thought of were: * Add some magic to the parser, so that if it encounters a # at the start of a line, it bails out and restarts again after preprocessing. * Only preprocess .cpp.hs or .hscpp or some other special suffix as having cpp directives. * Look into the file for some sort of command line arguments pragma on the first line denoting preprocessing. Thoughts? Thanks Neil
