Documentation
Lifted expressions for pattern match checking.
Literals (simple and overloaded ones) for pattern match checking.
truePmExpr :: PmExpr Source #
Expression True
falsePmExpr :: PmExpr Source #
Expression False
isFalsePmExpr :: PmExpr -> Bool Source #
Check whether a PmExpr is syntactically equal to term False.
isNotPmExprOther :: PmExpr -> Bool Source #
Check if an expression is lifted or not
substComplexEq :: Name -> PmExpr -> ComplexEq -> Either ComplexEq ComplexEq Source #
Substitute in a complex equality. We return (Left eq) if the substitution affected the equality or (Right eq) if nothing happened.
filterComplex :: [ComplexEq] -> [PmNegLitCt] Source #
pprPmExprWithParens :: PmExpr -> PmPprM SDoc Source #
