convertLit :: ConvertIdX a b => HsLit a -> HsLit b Source #

Convert a literal from one index type to another, updating the annotations according to the relevant Convertable instance

pp_st_suffix :: SourceText -> SDoc -> SDoc -> SDoc Source #

pmPprHsLit :: SourceTextX x => HsLit x -> SDoc Source #

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

isCompoundHsLit :: HsLit x -> Bool Source #

Returns True for compound literals that will need parentheses.

isCompoundHsOverLit :: HsOverLit x -> Bool Source #

Returns True for compound overloaded literals that will need parentheses when used in an argument position.
