Re: [Haskell-cafe] JavaScript (SpiderMonkey, V8, etc) embedded in GHC?
Nice! Thanks! I'll have a go with it today or tomorrow. There is not much yet. Have a look at the specs [1] to see what currently works.

Re: [Haskell-cafe] JavaScript (SpiderMonkey, V8, etc) embedded in GHC?
Out of curiosity: wouldn't it make more sense to focus on the other direction (calling Haskell from V8)? Roughly like: I guess it really depends what you are after. If you want to cabalize existing JS libs, then I think bindings to V8 make perfect sense ;) Cheers, Simon ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe

I just started something [1]. Cheers, Simon [1] https://github.com/sol/v8 Out of curiosity: wouldn't it make more sense to focus on the other direction (calling Haskell from V8)? Roughly like: - devices/GUI: Javascript/HTML/CSS in the browser/webview - server/IO+lightweight computation: Javascript on node.js/V8 - server/computation+algorithms+parallelism+concurrency+..: Haskell on GHC Also, if I recall correctly, the behind the scenes upgrade of evented IO in GHC was never carried over to Windows. Since node.js had to solve similar issues, and did so by using libuv, perhaps there is an opening for completing the cross- platform support for efficient evented IO in GHC, reusing node's library-level efforts[1,2,3]? Just a thought.. Claus [1] https://github.com/joyent/libuv Its purpose is to abstract IOCP on Windows and libev on Unix systems.

Re: [Haskell-cafe] JavaScript (SpiderMonkey, V8, etc) embedded in GHC?
Thanks Greg, interesting thought. 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. Still, that's another moving part I'd just as soon not have. Strange there's no JavaScript embedding in GHC, or there doesn't seem to be.
