The id you are getting is a monomorphic id, with a type like a-a, not the

happen then.

Hi,
I'm currently writing a tutorial on web applications using Haskell. I know
the pros and cons of each server-side library (Yesod, Snap, Scotty, Warp,
Happstack), but I'm looking for the right choice for client-side
programming that converts Haskell to JavaScript. I've finally come to Fay

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
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
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

Awesome/ thanks for sharing. It's worth noting that criterion is also
pretty great for microbenchmarks too. On my machine I get pretty good
timing accuracy on anything that takes more than 20 nanoseconds.

Here are some points I'd like to emphasize in addition to the threads

Fay tries to be very simple, the code base is small (~4800 LoC). This

important for open source

I second the recommendation to look at Haste. It's what I would pick for a

In the big picture, Haste and GHCJS are fairly similar. But when it comes

that it's basically an emulator, where

To give a very casual explanation, both mains are of the form do this a
bunch of times and return the results. Your first is do nothing and
return the ()s, but importantly, it has to execute all those nothings.
Your second is print hello a bunch and return the ()s. The list it wants

Er, I seem to have misread and thought you were doing infinite replicateM,
