Elm.Pretty is a pretty printer for Elm syntax trees. It makes use of
the-sett/elm-pretty-printer to best fit the code to a given character width.
It aims to output code that is fully stable with respect to elm-format in the
sense that running elm-format on the output should have no effect at all. The
advantage of this is that if generated code moves to being edited by hand, there
will not be a large white-space only diff created when elm-format is applied.
Pretty prints a file of Elm code.
