splitModule

Arguments

:: MonadClean m

=> (Maybe Name -> ModuleName)

Map declaration to new module name. The name Nothing is used for instance declarations.

-> FilePath

-> m [ModuleResult]

Split each of a module's declarations into a new module. Update the imports of all the modules in the moduVerse to reflect the split. For example, if you have a module like

 module Start (a, b, (.+.)) where
 import
 a = 1 + a
 b = 2
 c = 3
 c' = 4
 (.+.) = b + c

After running splitModuleDecls Start.hs the Start module will be gone. The a and b symbols will be in new modules named Start.A and Start.B. Because they were not exported by Start, the c and c' symbols will both be in a new module named Start.Internal.C. And the .+. symbol will be in a module named Start.OtherSymbols. Note that this module needs to import new Start.A and Start.Internal.C modules.

If we had imported and then re-exported a symbol in Start it would go into a module named Start.ReExported. Any instance declarations would go into Start.Instances.

splitModuleDecls :: MonadClean m => FilePath -> m [ModuleResult]

Do splitModuleBy with the default symbol to module mapping (was splitModule)

defaultSymbolToModule

Arguments

:: ModuleInfo

Parent module name

-> Maybe Name

-> ModuleName

This can be used to build function parameter of splitModule, it determines which module should a symbol be moved to.
