- syntax highlighting - quick navigation (goto symbol, goto instance, find usages, etc) - code completion
Emacs with haskell-mode can do this.
- cross module refactoring
Refactoring doesn't feature as heavily in Haskell workflow as, say, Java, just because of the differing natures of the language (e.g. Haskell features more powerful polymorphism). So you can pretty much get by without refactoring tools, although some do exist. HaRe, for example, has Emacs integration.
- "debugging" (not imperative debugging, so no breakpoints, but just plugging in a visualizer/pretty printer for a function in a separate dedicated window, like what http://www.apple.com/shake does on each "node")
Debugging in Haskell is a bit of a no-show for now. There's some support in the latest versions of GHCi, but I don't think it's very mature. -David House, dmhouse@gmail.com
