scripts to automatically manage imports or refactor modules

Question

Does anyone know of tools to manage Haskell imports? Sometimes, I want to refactor things by moving them to another file, and a script to generate the minimal set of imports [for the new file] would be nice.

Answer 1

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

Answer 2

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