Comment (by mpickering):

 This is essentially a duplicate of #10961. I agree it should be easier to
 use the parser and don't think there is a good reason why it isn't pure.
 FWIW, `ghc-exactprint` provides a bit of a nicer interface around the
 entry points which you might want to use in the mean time.
