scripts to automatically manage imports or refactor modules

Does anyone know of tools to manage Haskell imports? Sometimes, I want to refact开发者_运维知识库or things by moving them to another file, and a script to generate the minimal set of imports [for the new file] would be nice.

GHC can tell you which imports are required; simply add the -fwarn-unused-imports flag.

There's a program called fix-imports that can generate a minimal set of imports for you. It only works for qualified imports, though.
