Hi Kris,
No offense taken, it was an argument that works to shut down constructive discussion of how to get Haskell running on mobile, a task which has perplexed me for several long days. I agree most apps are pretty terrible, at least on iOS though, despite the percentages being wildly off there are still a few hundred apps that are very well done and thoughtful, none of them using Haskell I'm sure.
Yup! Most of the time apps are merely "translated" versions of rails frontends. (For better or for worse, I assume that if we were to port haskell to work with Android really it would be mostly to appease my purity.)
I'm looking to pass Haskell lists of musical data and return processed musical ideas from it (not audio, not realtime). I was also planning on handling a database within Haskell as the information contained would be used by the music processing and from what I have read Haskell interfaces to SQL far more readily than with a C++ orm type solution. I was planning on working with Haskells Euterpea as base to build my ideas off of, my I might end up rolling my own similar library as my aims are a bit different than theirs.
I'm not sure I understand completely, but I agree this isn't a bad idea.
Everything else would be C++, including the interface, audio and dsp processing etc. I already have the C++ stuff running on my phone. I have read about the difficulty of getting Haskell working in real world scenarios, but as far as I understand my plans for it are fairly well suited to it.
I don't disagree!
Since much of the documentation online about Haskell seems to be out of date, its tough to get a general feel for whats working. I see people mention that cross-compilation was finished a while back which should allow for targeting arm but nothing concrete and the website gives conflicting info. I've also considered using GHC to generate C to paste into the project but it seems there have been and may be more integrated ways to get it running.
I am venturing into my embarrassing lack of knowledge about GHC internals here, but how easily would the run time system work on Android..? I had assumed a large part of the effort into getting OCaml to work on iPhone went into the runtime system, no? If you're (Andrew or anyone) still interested in pursuing this I would be interested in helping out, I have some Android internals knowledge and would be glad to lend a hand. One major thing that seems to be necessary is congealing all the (mis/outdated)information into the wiki article on haskell.org. kris
