Methods

showsPrec :: Int -> LoneSig -> ShowS

show :: LoneSig -> String

showList :: [LoneSig] -> ShowS

type LoneSigs Source #

Arguments

 = Map Name LoneSig

We retain the Name also in the codomain since Name as a key is up to Eq Name which ignores the range. However, without range names are not unique in case the user gives a second definition of the same name. This causes then problems in replaceSigs which might replace the wrong signature.

Another reason is that we want to distinguish different occurrences of NoName in a mutual block (issue #4157). The NoName in the codomain will have a unique NameId.

type NiceWarnings Source #

Arguments

 = [DeclarationWarning]

Stack of warnings. Head is last warning.

initNiceState :: NiceState Source #

Initial nicifier state.

lensNameId :: Lens' NiceState NameId Source #

nextNameId :: Nice NameId Source #

Handling the lone signatures, stored to infer mutual blocks.

loneSigs :: Lens' NiceState LoneSigs Source #

Lens for field _loneSigs.

addLoneSig :: Range -> Name -> DataRecOrFun -> Nice Name Source #

Adding a lone signature to the state. Return the name (which is made unique if isNoName).

removeLoneSig :: Name -> Nice () Source #

Remove a lone signature from the state.

getSig :: Name -> Nice (Maybe DataRecOrFun) Source #

Search for forward type signature.

noLoneSigs :: Nice Bool Source #

Check that no lone signatures are left in the state.

forgetLoneSigs :: Nice () Source #

checkLoneSigs :: LoneSigs -> Nice () Source #

Ensure that all forward declarations have been given a definition.

breakImplicitMutualBlock :: Range -> String -> Nice () Source #

Ensure that all forward declarations have been given a definition, raising an error indicating *why* they would have had to have been defined.

loneFuns :: LoneSigs -> [(Name, Name)] Source #

Get names of lone function signatures, plus their unique names.

loneSigsFromLoneNames :: [(Range, Name, DataRecOrFun)] -> LoneSigs Source #

Create a LoneSigs map from an association list.

terminationCheckPragma :: Lens' NiceState TerminationCheck Source #

Lens for field _termChk.

withTerminationCheckPragma :: TerminationCheck -> Nice a -> Nice a Source #

coverageCheckPragma :: Lens' NiceState CoverageCheck Source #

universeCheckPragma :: Lens' NiceState UniverseCheck Source #

Lens for field _uniChk.

withUniverseCheckPragma :: UniverseCheck -> Nice a -> Nice a Source #

getUniverseCheckFromSig :: Name -> Nice UniverseCheck Source #

Get universe check pragma from a data/rec signature. Defaults to YesUniverseCheck.

catchallPragma :: Lens' NiceState Catchall Source #

Lens for field _catchall.

popCatchallPragma :: Nice Catchall Source #

Get current catchall pragma, and reset it for the next clause.

withCatchallPragma :: Catchall -> Nice a -> Nice a Source #

niceWarning :: DeclarationWarning -> Nice () Source #

Add a new warning.

declarationException :: HasCallStack => DeclarationException' -> Nice a Source #
