Returns true if the named file is a directory, or a symlink that points at a directory, and false otherwise.
file_name can be an IO object.
File.directory?(".")
Creates a remote directory.
Removes a remote directory.
The path to the data directory for this gem.
Return the directories that Specification uses to find specs.
Set the directories that Specification uses to find specs. Setting this resets the list of known specs.
Same as Dir.mkdir, except multiple directories are allowed.

Quietly ensure the Gem directory dir contains all the proper subdirectories. If we can’t create a directory due to a permission problem, then we will silently continue.
If mode is given, missing directories are created with this mode.
World-writable directories will never be created.
Paths where RubyGems’ .rb files and bin files are installed
Calls the block once for each [key, value] pair in the database. Returns self.
Yields the name and value of each struct member in order. If no block is given an enumerator is returned.
Customer = Struct.new(:name, :address, :zip) joe = Customer.new("Joe Smith", "123 Maple, Anytown NC", 12345) joe.each_pair {|name, value| puts("#{name} => #{value}") }
Produces:
name => Joe Smith address => 123 Maple, Anytown NC zip => 12345
Executes block for each key in the database, passing the key and the corresponding value as a parameter.
Yields all attributes (as symbols) along with the corresponding values or returns an enumerator if no block is given.
require "ostruct" data = OpenStruct.new("country" => "Australia", :capital => "Canberra") data.each_pair.to_a # => [[:country, "Australia"], [:capital, "Canberra"]]
