Temporarily turn off warnings. Intended for tests only.
Signs in with the RubyGems API at sign_in_host
and sets the rubygems API key.
Wraps text
to wrap
characters and optionally indents by indent
characters
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 git.io/JJgZI
Displays a warning statement
to the warning output location. Asks a question
if given.
Returns the string that is used to indent levels in the JSON
text.
Sets the string that is used to indent levels in the JSON
text.
Is this tar entry a symlink?
Rewinds to the beginning of the tar file entry
@return [String] a string suitable for debugging
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.

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
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 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
