om-plugin-imports

This plugin behaves similarly to the native GHC options -ddump-minimal-imports. If (and only if) you specify a -dumpdir directory to GHC, this plugin will emit files to that directory that contain a normalized, complete set of explicit imports for your module. This is sort of what -ddump-minimal-imports does, but -ddump-minimal-imports has the following deficiencies:

• It will not always produce output that satisfies -Wmissing-import-lists. E.g. it will sometimes produce something like:

  import Foo (Bar(..))
  

• It will explicitly import all the names from modules which are already qualified, E.g:

  import qualified Foo as F (foo, bar, baz)
  

This plugin solves these problems. It will dump a file in the user-supplied -dumpdir of the form <dumpdir>/<module-name>.full-imports. The file will contain a set of imports which can be copy/pasted over the imports in your module in a way that satisfies -Wmissing-import-lists.
