TemplateHaskellUtils

useful functions for you to write template Haskell code

some examples ** Prettyprint

> runQ [| (1+1) * 5|] >>= pp -- or use
> printiQ  [| (1+1) * 5|]
InfixE (Just InfixE (Just LitE (IntegerL 1))
                  (VarE (Name (OccName "+")
                               (NameG' VarName
                                       (PkgName "base")
                                       (ModName "GHC.Num"))))
                   (Just LitE (IntegerL 1)))
      (VarE (Name (OccName "*")
                  (NameG' VarName
                          (PkgName "base")
                          (ModName "GHC.Num"))))
      (Just LitE (IntegerL 5))
