It would work the other way around, but it'd be easy enough to set up a node server to run the javascript. There's no IO allowed or any other blocking operations so I can make this all automatic.

<br>
I've looked around with no success… this surprises me actually. Has anyone embedded SpiderMonkey, V8, or any other relatively decent JavaScript interpreters in GHC (using the FFI)?<br>
<br>
I did find <a href="http://justinethier.github.com/husk-scheme/" target="_blank">http://justinethier.github.com/husk-scheme/</a> which is a scheme R5RS implementation (I could make this work). There's also some work done embedding Lua. I also found a number of packages that compile javascript to Haskell, or the other way around, but I don't need that kind of thing.<br>
<br>
All I really need is to allow users to write some JavaScript that accepts a single JSON 'file/string' from my Haskell program and produces another JSON 'file/string' that my Haskell program will accept.<br>
<br>
Thanks,<br>
