Translating Haskell to C for use on iPhone

Question

I've written a Haskell library I would like to include in an iPhone app. It makes heavy use of Haskell's functional abilities, currying, etc. and rewriting in Objective-C would be tough.

Is it possible to automatically translate Haskell to C? or dig out an intermediate C representation from one of the compilers?

Apple's developer agreement forbids statically linking one of the lightweight Haskell interpreters, not that I'm keen on that solution.

"Apple's developer agreement forbids statically linking one of the lightweight Haskell interpreters" -- Not anymore, I think. The only thing it forbids is running *downloaded* code. However, as long as the code comes from *inside* your app (i.e. it is part of your submission to the App Store), they don't care *how* you execute it. That stupid "only C, C++, Objective-C and ECMAScript" restriction was removed. — Jörg W Mittag, Jan 02 '11 at 01:12

http://repetae.net/computer/jhc/ compiles to fairly standard C. It might be possible to use it.

But beware that it may be very slow if you make excessive use of laziness. – fuz Jan 02 '11 at 02:41

Have a look at the ghc-ios project:
