Multi-language bindings to JavaScript engine V8

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.

Go

v8eval requires Go 1.10 or later.

git clone https://github.com/sony/v8eval.git ${GOPATH}/src/github.com/sony/v8eval
${GOPATH}/src/github.com/sony/v8eval/go/build.sh install

In the case of Linux, you need to build your Go program with build.sh:

${GOPATH}/src/github.com/sony/v8eval/go/build.sh go build

Python

pip install v8eval

Ruby

gem install v8eval

Documentation

Go

See godoc.org.

Examples

Go

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)
  v8 = V8Eval::V8.new
  v8.eval('var add = (x, y) => x + y;')
  v8.call('add', [x, y])
end

Passing Flags Down To V8

Hello,
I really love the repo. Once everything is installed it has been very helpful. We are looking to use v8eval to build a very parallel go server that sends requests to javascript v8 to process and return information.

Everything in v8eval makes this pretty easy. On NewV8() a new V8 isolate is created and returned to the user. This is perfect for running v8 in many different threads concurrently. We want our server to be able to do some data intensive work and have many different isolates running at once. To do this we really need more than the 64 bit minimum memory, 1.4 GBs (https://bugs.chromium.org/p/v8/issues/detail?id=847).

The way node handles this, and the way that seems best moving forward, is to pass a list of command line arguments through to V8's SetFlagsFromCommandLine function. I think it would be a good idea to pass a list of args to Initialize() and have that list passed on to setFlags function. This not only would enable more memory, but also manual garbage collection and more fine tuning of the v8 engine.

I was planning on forking and trying to do this myself, but was wondering if you had thoughts about the problem at all or had any suggestions on how best or where best to set these flags?

Thanks and I will submit a PR when I am done.

Python six addresses this by basically doing this:

PY3 = sys.version_info[0] == 3
if PY3:
    string_types = str,
else:
    string_types = basestring,

Anywhere you use basestring you may replace it with string_types.

Note: Python 3.x strings can contain Unicode characters, and Python 2.x basestring only contain bytes (with unicode characters being multiple escaped bytes). This may or many not be a problem for v8, but you should be well aware that Python 2 and 3 are very different in this regard to string types.

This may not be the only compatibility issue regarding Python 3.x.

install_v8 missing gclient sync

The install_v8 function of build.sh should also call gclient sync otherwise some key components don't get fetched namely the v8/thrid-party/llvm-build where the build.sh is expecting to find the clang compiler so the build later just fails.

New examples needed to show how to use Node's require() function.

Also, ones that call scripts rather than inlined functions.

Hello, when I try pip install v8eval, I run into an error with a gclient.py command that seems to be used on build. I'm happy to dig around, but a quick search didn't bring up much info. Log below (note that in the log I was using anaconda, but ran into the same area with my system python).

Hello,

In the past i was able to install v8eval without major problems on Ubuntu 18.04, but now after reinstalling the OS (still on 18.04), i have following problem:

sudo -H pip install v8eval --no-cache-dir

Thank you in advance,

Get V8 Heap Usage

If you are running long running v8 applications and are giving them lots of memory, it is often very useful to be able to inspect how much memory / heap each v8 isolate is using.

I propose that we add a simple method to v8.go on the v8 struct and the V8 interface that gives you back a struct where the attributes are uint64 values representing information about the isolates heap usage.

Will send a pr with my proposal shortly.

Pip stuck on installing

It been so many minutes since it stuck there? any idea?

Update to V8 7.9?

What would it take to update to the latest version of V8?

Can I run this on Windows if I am able to build v8 separately?

Proposal: Add option to set bind IP for debugger

My reading of this line is that currently the debugger only ever binds itself to 127.0.0.1. This is a sensible default, but it makes attaching a remote debugger to a running v8eval instance impossible without layering on additional tooling.

Would you be open to making this configurable, probably as a constructor to EnableDebugger? If so I might look into providing a patch.
