Source-language literals

Documentation

module Language.Haskell.Syntax.Lit

convertLit :: forall (p1 :: Pass) (p2 :: Pass). HsLit (GhcPass p1) -> HsLit (GhcPass p2)

Convert a literal from one index type to another

hsLitNeedsParens :: PprPrec -> HsLit x -> Bool

hsLitNeedsParens p l returns True if a literal l needs to be parenthesized under precedence p.

See Note [Printing of literals in Core] in GHC.Types.Literal for the reasoning.

hsOverLitNeedsParens :: PprPrec -> HsOverLit x -> Bool

hsOverLitNeedsParens p ol returns True if an overloaded literal ol needs to be parenthesized under precedence p.

negateOverLitVal :: OverLitVal -> OverLitVal

overLitType :: HsOverLit GhcTc -> Type

pmPprHsLit :: forall (x :: Pass). HsLit (GhcPass x) -> SDoc

pmPprHsLit pretty prints literals and is used when pretty printing pattern match warnings. All are printed the same (i.e., without hashes if they are primitive and not wrapped in constructors if they are boxed). This happens mainly for too reasons: * We do not want to expose their internal representation * The warnings become too messy
