(v8eval
Multi-language bindings to JavaScript engine V8.
Currently v8eval provides Go, Python and Ruby bindings to the latest V8 7.1 and supports Linux and Mac OS X.
v8eval uses SWIG and can be extended easily for other languages.
Pre-installation
Linux
See Dockerfile.
Mac
See .travis.yml.
Installation
The installation takes several tens of minutes due to V8 build.

func Add(x, y int) int {
var v8 = v8eval.NewV8()

var sum int
v8.Call("add", []int{x, y}, &sum)
return sum
}
Python
