Re: [Haskell-cafe] Tutorial on JS with Haskell: Fay or GHCJS?

In my opinion haste is somewhere between Fay and ghcjs. It supports more than Fay, but in difference to ghcjs some PrimOps are not supported (weak pointers for example). It is a little bit more "direct" than ghcjs, in the sense that it does not need such a big rts written in js. I like haste :). What I wonder is how the outputs of these 3 compilers compare speed wise. On 09/04/2013 11:11 AM, Alejandro Serrano Mena wrote:

I haven't looked at Haste too much, I'll give it a try.

My main problem is that I would like to find a solution that will continue working in years (somehow, that will became "the" solution for generating JS from Haskell code). That's why I see GHCJS (which just includes some patches to mainstream GHC) as the preferred solution, because it seems the most probable to continue working when new versions of GHC appear.

Hi, I'm also interested in that.

Have you already evaluated haste?

It does not seem to have any of your cons, but maybe others.

What I particularly miss from all solutions is the ability to simply call parts written in Haskell from Javascript, e.g. to write `fib` and then integrate it into an existing Javascript application (they are all more interested in doing the other direction).
