I believe the way is done in hint is something like this (untested):
showType t =
do -- Unqualify necessary types
-- (i.e., do not expose internals)
unqual <- GHC.getPrintUnqual
return $ GHC.showSDocForUser unqual (GHC.pprTypeForUser False
t) -- False means 'drop explicit foralls'
Hope that helps

I was wondering how given a Type I can get a pretty printed type out
of it.
I’m currently using showSDocUnqual . pprType . snd . tidyOpenType
emptyTidyEnv
But this has the problem that predicates don’t get printed, anyone
know how GHCi does this?
Thanks,
