Howdy! I've been using https://github.com/jspahrsummers/ObjectiveHaskell/ as my bridge between the two worlds (with some modifications for iOS that I'll be posting soon). Haskell has a wonderful FFI that lets you easily call C/Objective-C from Haskell and vice versa. There's also Manuel Chakravarty's extremely exciting "Inline Objective-C" project (coming soon) that allows you to embed Objective-C code directly into…

Is it related to Fujimoto et al's space-time memory? There was also a project called Stampede that that used a similar name to mean something completely different. Or is it just a name?

This is brilliant news! Would it be possible to drop a cross compiled Haskell library into a Xamarin project and call into it from the .Net (F#) world? That would be the killer feature for me! Also not much mention of android here - is it possible to target android with Haskell at the moment?

I believe this is the relevant project: https://github.com/neurocyte/ghc-android Joey Hess has been using it to build git-annex for Android. http://git-annex.branchable.com/install/Android/ And much of the work we did simply improved support for cross-compilation in general, so Android support should be better than ever! : )

Anybody here know, off the cuff, if the GHC packaged in Homebrew is compiled correctly to utilize the wrapper scripts out of the box, or if I'd need to build the cross-compiler myself as described in the linked documentation?

Nope. I also strongly recommend against using the normal "brew" formulas for haskell tools, its only by PROACTIVE efforts by mac using haskellers that the standard brew aren't a complete disaster (or at least, wont' be a disaster, soonish). I strongly recommend using standard haskell binary distributions, such as those prepared by GHC HQ, or the Haskell Platform folks, or perhaps any brew Tap that Darin Morrison or L…

Hmm. Well, looking at the Github repo activity, Darin is actively involved in the GHC formulae these days. In fact he's actively involved in getting Homebrew's GHC formula prepped for OS X Mavericks, which you note as an upcoming issue below. So that's encouraging. And while the stability of GHC/Haskell Platform was indeed questionable during 2012.2.0.0 and the beginning of 2012.4.0.0, they cleaned it up as time went…

I would love to also run the interpreter inside iOS to learn Haskell from a tablet. I will support a crowdfunding campaign.

Apple wouldn't permit this in the AppStore
