Re: [Haskell-cafe] GHC for mobile devices?

Yes, I've seen some of the work done on this and I think he's also looked into OCaml on Android. To be completely honest it's not really the language that's such the barrier: the hard truth is that any Android app doing anything of interest is necessarily going to be using the Android framework. Android programming (at least, presubaly iOS too) is not a lot of advanced construction, it's mostly dumb apps acting as web frontends, I'd posit that this is probably why people have been mostly content with the Android API for so long anyway. So the main barrier is being able to interface with the Java side of things (obviously) in a way that doesn't completely kill perf either (this sounds nontrivial...). Then you need to give a sane reimplementation of the Android API within Haskell. kris On Sat, Nov 10, 2012 at 12:59 AM, Mike Ledger wrote:

I would be so very happy to be able to program Haskell Android programs. I think the steps we'd need are to 1. Port GHC to ARM (done already?) and 2. Create a JVM calling convention for GHC (using JNI? I have no idea). Short of actually making a new calling convention for the JVM, maybe we could use the JNI to create a thin C wrapper that has the code we want to import normally.

Unfortunately I have no idea of where to start and very little experience with Android other than firing up Eclipse, playing around with simple applications and being very dissatisfied.

Awesome! Jeffrey Scofield has ported OCaml to iOS, so there's also experience there.

If you have interest in doing this, I have quite a bit of experience in Android hacking at the system level and above and would be glad to talk about what might need to happen. (Though I don't know the GHC internals / toolchain so well.)

One potential choice is Scala, though from my limited experience that's a very rough imitation of the uses for Haskell. (Though, obviously it works mostly out of the box because of the JVM compiler target..)

I've been writing up some thoughts on the Android activity lifecycle already interpreted with respect to FP, apps are quite functional already for a variety of reasons.

I'd love to use Haskell directly for making mobiles apps. How can we make this happen, porting GHC to Android, iOS, and Windows Phone?
