Helpers to take Chef::Config and create chef_fs and local_fs from it
# File lib/chef/chef_fs/config.rb, line 28 def initialize(chef_config = Chef::Config, cwd = Dir.pwd, options = {}) @chef_config = chef_config @cwd = cwd @cookbook_version = options[:cookbook_version] # Default to getting *everything* from the server. if !@chef_config[:repo_mode] if @chef_config[:chef_server_url] =~ /\/+organizations\/.+/ @chef_config[:repo_mode] = 'hosted_everything' else @chef_config[:repo_mode] = 'everything' end end end
The current directory, relative to server root
# File lib/chef/chef_fs/config.rb, line 112 def base_path @base_path ||= begin if @chef_config[:chef_repo_path] server_path(File.expand_path(@cwd)) else nil end end end
# File lib/chef/chef_fs/config.rb, line 47 def chef_fs @chef_fs ||= create_chef_fs end
# File lib/chef/chef_fs/config.rb, line 51 def create_chef_fs require 'chef/chef_fs/file_system/chef_server_root_dir' Chef::ChefFS::FileSystem::ChefServerRootDir.new("remote", @chef_config, :cookbook_version => @cookbook_version) end
# File lib/chef/chef_fs/config.rb, line 60 def create_local_fs require 'chef/chef_fs/file_system/chef_repository_file_system_root_dir' Chef::ChefFS::FileSystem::ChefRepositoryFileSystemRootDir.new(object_paths) end
Print the given server path, relative to the current directory
# File lib/chef/chef_fs/config.rb, line 123 def format_path(entry) server_path = entry.path if base_path && server_path[0,base_path.length] == base_path if server_path == base_path return "." elsif server_path[base_path.length,1] == "/" return server_path[base_path.length + 1, server_path.length - base_path.length - 1] elsif base_path == "/" && server_path[0,1] == "/" return server_path[1, server_path.length - 1] end end server_path end
# File lib/chef/chef_fs/config.rb, line 56 def local_fs @local_fs ||= create_local_fs end
Returns the given real path’s location relative to the server root.
If chef_repo is /home/jkeiser/chef_repo, and pwd is /home/jkeiser/chef_repo/cookbooks, server_path(‘blah’) == ‘/cookbooks/blah’ server_path(‘../roles/blah.json’) == ‘/roles/blah’ server_path(‘../../readme.txt’) == nil server_path(‘*/ab’) == ‘/cookbooks/*/ab’ server_path(‘/home/jkeiser/chef_repo/cookbooks/blah’) == ‘/cookbooks/blah’ server_path(‘/home/*/chef_repo/cookbooks/blah’) == nil
If there are multiple paths (cookbooks, roles, data bags, etc. can all have separate paths), and cwd+the path reaches into one of them, we will return a path relative to that. Otherwise we will return a path to chef_repo.
Globs are allowed as well, but globs outside server paths are NOT (presently) supported. See above examples. TODO support that.
If the path does not reach into ANY specified directory, nil is returned.

"/#{name}" : "/#{name}/#{relative_path}" end end end # Check chef_repo_path Array(@chef_config[:chef_repo_path]).flatten.each do |chef_repo_path| realest_chef_repo_path = Chef::ChefFS::PathUtils.realest_path(chef_repo_path) if absolute_pwd == realest_chef_repo_path return '/' end end nil end
