Documentation
type ErrorPackage = Text Source
Simple synonym to indicate package names
type ErrorVersion = Text Source
Simple synonym to indicate package versions
type ErrorModule = Text Source
Simple synonym to indicate module names
type ErrorIdentifier = Text Source
Simple synonym to indicate identifier names
data ErrorCause Source
The possible error causes
Constructors
| UnknownPackage ErrorPackage ErrorVersion | Package referenced in cabal file is unknown, needs to be installed, with the given version (may be -any) |
| UnreferencedPackage ErrorPackage | A module from the package is referenced but the package is not in the build depends section of the cabal file |
| MissingType Text | The type signature is missing |
| MispelledModule Text [ModuleSuggestion] | A module has been mispelled, give suggestions |
| MispelledIdentifier ErrorIdentifier [IdentifierSuggestion] | Identifier mispellt |
| UselessImport ErrorModule | a full import statement is not needed (or only for instances) |
| UselessImportElement ErrorModule Text | an import element is not needed |
| MissingOption Text | A GHC option is missing (to add in current source file or in Cabal file) |
| MissingExtension Text | An extension is missing (to add in current source file or in Cabal file) |
| ConstructorImported ErrorModule ErrorType ErrorIdentifier | A constructor is imported from a module, instead of the type |
| IncorrectCabalVersion Text | An incorrect cabal version is used, the proper version range is given in the field |
