Returns a value representing the “cost” of transforming str1 into str2 Vendored version of DidYouMean::Levenshtein.distance from the ruby/did_you_mean gem @ 1.4.0 github.com/ruby/did_you_mean/blob/2ddf39b874808685965dbc47d344cf6c7651807c/lib/did_you_mean/levenshtein.rb#L7-L37

Displays a warning statement to the warning output location. Asks a question if given.

Format and print out counters as a String. This returns a non-empty content only when --yjit-stats is enabled.

Format large numbers with comma separators for readability

Return current keep_script_lines status. Now it only returns true of false, but it can return other objects in future.

It set keep_script_lines flag. If the flag is set, all loaded scripts are recorded in a interpreter process.

Same as Enumerator#with_index(0), i.e. there is no starting offset.

If no block is given, a new Enumerator is returned that includes the index.

Returns the value of the given instance variable, or nil if the instance variable is not set. The @ part of the variable name should be included for regular instance variables. Throws a NameError exception if the supplied symbol is not valid as an instance variable name. String arguments are converted to symbols.

class Fred
  def initialize(p1, p2)
    @a, @b = p1, p2
  end
end
fred = Fred.new('cat', 99)
fred.instance_variable_get(:@a)    #=> "cat"
fred.instance_variable_get("@b")   #=> 99

Sets the instance variable named by symbol to the given object. This may circumvent the encapsulation intended by the author of the class, so it should be used with care. The variable does not have to exist prior to this call. If the instance variable name is passed as a string, that string is converted to a symbol.

class Fred
  def initialize(p1, p2)
    @a, @b = p1, p2
  end
end
fred = Fred.new('cat', 99)
fred.instance_variable_set(:@a, 'dog')   #=> "dog"
fred.instance_variable_set(:@c, 'cat')   #=> "cat"
fred.inspect                             #=> "#<Fred:0x401b3da8 @a=\"dog\", @b=99, @c=\"cat\">"

Removes the named instance variable from obj, returning that variable’s value. String arguments are converted to symbols.

class Dummy
  attr_reader :var
  def initialize
    @var = 99
  end
  def remove
    remove_instance_variable(:@var)
  end
end
d = Dummy.new
d.var      #=> 99
d.remove   #=> 99
d.var      #=> nil

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

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

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 given class variable is defined in obj. String arguments are converted to symbols.

class Fred
  @@foo = 99
end
Fred.class_variable_defined?(:@@foo)    #=> true
Fred.class_variable_defined?(:@@bar)    #=> false

Similar to instance_method, searches public method only.

Returns true if the named public method is defined by mod. If inherit is set, the lookup will also search mod’s ancestors. String arguments are converted to symbols.

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

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

Returns true if the named private method is defined by mod. If inherit is set, the lookup will also search mod’s 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.private_method_defined? "method2", true    #=> true
C.private_method_defined? "method2", false   #=> false
C.method_defined? "method2"                  #=> false

Returns true if the named protected method is defined mod. If inherit is set, the lookup will also search mod’s ancestors. String arguments are converted to symbols.

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

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