Hey Torben,

If you're familiar with Ruby you should be able to read the Berkshelf source to get an idea of how I implemented the metadata keyword. The Berkshelf code base is pretty friendly and you should feel free to use any of the classes which aren't marked @api private in your own codebase.

Is there a reason you aren't using Berkshelf for this? The use that you are describing is 100% supported and something that I use in my projects everyday. (overriding the locations of the dependencies found in the metadata)

Um, berkshelf. :)

You can probably figure out some of the work from there. But I have no

idea if the Chef cookbook metadata parser will allow for anything

other than a version string following a cookbook name.

Background:

First, I want to emulate Berkshelfs 'metadata' keyword inside a librarian

Cheffile.

Then I want to override the location for some of the metadata-defined

cookbook dependencies in the Cheffile (e.g. use github branch rather than

community site)

Ohai Chefs,

what's the easiest way to obtain the cookbook dependencies defined in

metadata.rb (only direct dependencies are required)?

I'm not too firm with the chef internals yet, thus my first idea was to

evaluate metadata.rb and recording the `depends` calls via `method_missing`

- but this doesn't feels quite right...

Thanks!

Torben
