It would be hard, but the languages are nearly identical, so the translation is pretty trivial AST transforming. I'm also not looking to be complete: my main goal is sharing client and server-side code.
Thanks to Malcolm Wallace for the haskell-src-extensions suggestion, it looks great.

Compiling Haskell to another language is huge effort, maybe instead of
this you can compile Haskell to JS using GHCJS or Fay, and then use
Elm FFI to use compiled Haskell functions.

I'm looking at writing a simple Haskell to Elm translator. Thankfully, the
Elm compiler is in Haskell, so I'm just trying transforming syntax trees.

I'm wondering, is there a standard way to do this sort of thing? Template
Haskell looked promising, but it seems there isn't much of a way to do
introspection on function definition. Has there been any work/progress on
this?

The GHC API seemed useful for compiling, but it seems tricky to use, and I
haven't been able to find many tutorials for this sort of thing. I could
just be looking in the wrong place.

What are the ways I could go about this? Are there any similar projects I
could use as reference? What packages are useful for generating and
manipulating Haskell ASTs? Does anybody have experience in this area they
could share?

I've posted a similar question to the Haskell Reddit at
http://www.reddit.com/r/haskell/comments/1u55rl/standard_way_to_translate_haskell_to_other/.

Thanks!
