Storing callbacks (v8::value::Function) in a struct

[jeromegn]

Hey, I know this repo is not maintained anymore, but thought I'd give it a shot.

I had the hardest time storing a v8 Function in a struct. Here's what I was encountering: https://gist.github.com/jeromegn/40727cf0eaa8e18734b0822b5ffd14bc

With a little help from IRC, I was able to get it to work by wrapping the value::Function with a Rc<RefCell<value::Function>>, but I don't think that's the right way?

I wish this was maintained, it's a really good bindings implementation. There aren't many out there given the complexity of v8.

Also, worth noting building this project is a bit broken (I'm not entirely sure which environment variables to use, and they seem to assume a directory structure.) I was able to build everything by putting v8 in /usr/local/{lib,include} and not using any environment variables.

I used v8 5.7.x from the ruby libv8 gem which made this entirely more easy. I bet you could link to it in the readme for a very easy way to install v8 for a bunch of platforms. All you have to do is download the gem, untar (a gem is just a tarball) and get to the vendor folder with pre-compiled v8 for your platform.
