Returns 1.

Returns the value as a rational. The optional argument eps is always ignored.

Terminates thr and schedules another thread to be run.

If this thread is already marked to be killed, exit returns the Thread.

If this is the main thread, or the last thread, exits the process.

Returns the name at the definition of the current method as a Symbol. If called outside of a method, it returns nil.

Returns x/y;

Rational(1, 2)   #=> (1/2)
Rational('1/2')  #=> (1/2)
Rational(nil)    #=> TypeError
Rational(1, nil) #=> TypeError

Syntax of string form:

string form = extra spaces , rational , extra spaces ;
rational = [ sign ] , unsigned rational ;
unsigned rational = numerator | numerator , "/" , denominator ;
numerator = integer part | fractional part | integer part , fractional part ;
denominator = digits ;
integer part = digits ;
fractional part = "." , digits , [ ( "e" | "E" ) , [ sign ] , digits ] ;
sign = "-" | "+" ;
digits = digit , { digit | "_" , digit } ;
digit = "0" | "1" | "2" | "3" | "4" | "5" | "6" | "7" | "8" | "9" ;
extra spaces = ? \s* ? ;

See String#to_r.

Returns the /etc/passwd information for the user with specified login name.

The information is returned as a Passwd struct.

See the unix manpage for getpwnam(3) for more detail.

Example:

Etc.getpwnam('root')
#=> #<struct Etc::Passwd name="root", passwd="x", uid=0, gid=0, gecos="root",dir="/root", shell="/bin/bash">

Returns information about the group with specified name, as found in /etc/group.

The information is returned as a Group struct.

See the unix manpage for getgrnam(3) for more detail.

Example:

Etc.getgrnam('users')
#=> #<struct Etc::Group name="users", passwd="x", gid=100, mem=["meta", "root"]>

Returns a list of the private instance methods defined in mod. If the optional parameter is false, the methods of any ancestors are not included.

module Mod
  def method1()  end
  private :method1
  def method2()  end
end
Mod.instance_methods           #=> [:method2]
Mod.private_instance_methods   #=> [:method1]

Returns true if the named private method is defined by _ mod_ (or its included modules and, if mod is a class, its ancestors). String arguments are converted to symbols.

module A
  def method1()  end
end
class B
  private
  def method2()  end
end
class C < B
  include A
  def method3()  end
end

A.method_defined? :method1            #=> true
C.private_method_defined? "method1"   #=> false
C.private_method_defined? "method2"   #=> true
C.method_defined? "method2"           #=> false

Makes existing class methods private. Often used to hide the default constructor new.

String arguments are converted to symbols.

class SimpleSingleton  # Not thread safe
  private_class_method :new
  def SimpleSingleton.create(*args, &block)
    @me = new(*args, &block) if ! @me
    @me
  end
end

Returns the directories in the current shell’s PATH environment variable as an array of directory names. This sets the system_path for all instances of Shell.

Example: If in your current shell, you did:

$ echo $PATH
/usr/bin:/bin:/usr/local/bin

Running this method in the above shell would then return:

["/usr/bin", "/bin", "/usr/local/bin"]

Sets the system_path that new instances of Shell should have as their initial system_path.

path should be an array of directory name strings.

Returns the method identifier for the given object.

class A
  include ObjectSpace

  def foo
    trace_object_allocations do
      obj = Object.new
      p "#{allocation_class_path(obj)}##{allocation_method_id(obj)}"
    end
  end
end

A.new.foo #=> "Class#new"

See ::trace_object_allocations for more information and examples.

Sets a list of characters that cause a filename to be quoted by the completer when they appear in a completed filename. The default is nil.

Raises NotImplementedError if the using readline library does not support.

Gets a list of characters that cause a filename to be quoted by the completer when they appear in a completed filename.

Raises NotImplementedError if the using readline library does not support.

The default signing key path

The default signing certificate chain path

LocationPath

| RelativeLocationPath
| '/' RelativeLocationPath?
| '//' RelativeLocationPath

Downloads uri to path if necessary. If no path is given, it just passes the data.
