Readme for om-plugin-imports-

[back to package description]


This plugin behaves similarly to the native GHC options -ddump-minimal-imports. It will dump a file of the form <src-file>.full-imports. E.g. if the Haskell file was src/Foo/Bar.hs, then the dump file will be src/Foo/Bar.hs.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.

This is almost 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)
