[chef] Re: Re: Cookbook dependency graphing

["steve ." < >]

Hi Torbin,

I threw this together today on my Macbook, so I'm not surprised to find that you're having trouble getting it to work on Windows.  I'm pretty sure at least some of the depgraph codebase pre-dates Chef and it definitely _wasn't_ designed with Bundler in mind.  The gemspec is actually declared in the Rakefile.

However, I can attest that "rake gem" and "sudo gem install pkg/depgraph-VERSION.gem" got it installed for me.  No idea how easy it's going to be for you to get graphviz / ruby-graphviz functioning on Windows, though.

I don't know if the original gem is actively maintained at this point -- haven't put together a pull request yet -- but if you get it working on Windows, send me a PR and I'll merge it on in...

Guess I'm too stupid to install it...

In my `Gemfile`:

```

source 'https://rubygems.org'

gem 'depgraph', git: 'https://github.com/leftathome/depgraph.git'

```

Then I run:

```

D:\Repos\_github\_cookbooks\gitlab>bundle install

Is it supposed to be installed as a gem? 

Not a Ruby expert, but I don't see a .gemspec there. Might this be the problem?

Not sure if anyone's already doing something like this, but I made some REALLY MINOR modifications to the most ancient and venerable Ruby depgraph tool and got it parsing cookbook metadata instead of C# code and installed gems.

Default behavior is to parse, fire up graphviz and show you a dependency graph.  That's fine but I wanted it as a JSON object.

I added the -json switch to allow you to generate an object that looks like this:

{ "cookbook" : [ "dependency1", "dependency2"],

 ...

}

Hope someone out there finds this useful.
