Eq ModuleResult

Ord ModuleResult

Show ModuleResult

doResult :: (ModuVerse m, MonadDryRun m, MonadVerbosity m) => ModuleResult -> m ModuleResult

It is tempting to put import cleaning into these operations, but that needs to be done after all of these operations are completed so that all the compiles required for import cleaning succeed. On the other hand, we might be able to maintain the moduVerse here.

reportResult :: ModuleResult -> String

fixExport :: [ModuleName] -> ModuleName -> ModuleName -> ExportSpec l -> String -> String -> String -> Seq String -> Seq String

Update an export spec. The only thing we might need to change is re-exports, of the form module Foo.
