base_path() click to toggle source

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

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)

format_path(entry) click to toggle source

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
local_fs() click to toggle source
# File lib/chef/chef_fs/config.rb, line 56
def local_fs
  @local_fs ||= create_local_fs
end
server_path(file_path) click to toggle source

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/*/abserver_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.

# File lib/chef/chef_fs/config.rb, line 85
def server_path(file_path)
  pwd = File.expand_path(Dir.pwd)
  absolute_pwd = Chef::ChefFS::PathUtils.realest_path(File.expand_path(file_path, pwd))

  # Check all object paths (cookbooks_dir, data_bags_dir, etc.)
  object_paths.each_pair do |name, paths|
    paths.each do |path|
      realest_path = Chef::ChefFS::PathUtils.realest_path(path)
      if PathUtils.descendant_of?(absolute_pwd, realest_path)
        relative_path = Chef::ChefFS::PathUtils::relative_to(absolute_pwd, realest_path)
        return relative_path == '.' ? "/#{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
