v8eval 0.3.1

Run JavaScript engine V8 in Python

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

Mac

See .travis.yml.

Installation

The installation takes several tens of minutes due to V8 build.

import "github.com/sony/v8eval/go/v8eval"

func Add(x, y int) int {
    var v8 = v8eval.NewV8()
    v8.Eval("var add = (x, y) => x + y;", nil)

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

Python

import v8eval

def add(x, y):
    v8 = v8eval.V8()
    v8.eval('var add = (x, y) => x + y;')
    return v8.call('add', [x, y])

Ruby

require 'v8eval'

def add(x, y)
