Instance Method Details

#fetch_recipe(uri, source_root, recipe_name = nil) ⇒ Object

def fetch_recipe(uri, source_root, recipe_name = nil)
  if File.exists?(uri)
    normalize_fetched_project(uri, source_root, recipe_name)
  else
    raise UnknownPath, uri
  end
end

#normalize_fetched_project(path, store_path, recipe_name = nil) ⇒ Object

Takes a folder that is either a cookbooks/<recipes> structure, or assumed to be a singular <recipe>/ Copies it into store_path and resulting folder guaranteed to be in cookbooks/<recipes> structure

For example, if the path is:

path/
  ey-dnapi/
    libraries/
      engineyard.rb

Then the resulting store_path will be:

tmpdir/
  cookbooks/
    ey-dnapi/
      libraries/
        engineyard.rb

If path/cookbooks exists, then store_path will be a duplicate of path

Can override the <recipe> name with recipe_name

Returns a tuple:

  • path to a local folder structure that contains “cookbooks/<recipe name>”

  • recipe_name

#vendor_recipe_into_recipe(uri, recipe_vendor_path) ⇒ Object
