Generate syntax-colored, hyperlinked source code from Haskell or Objective-C

Are there any packages that can take a directory full of source code (Objective-C an开发者_JS百科d Haskell are the ones that interest me) and generate syntax-colored HTML from it where function names are links to their source code?

For haskell you can take a look at Haddock:
