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)
