Returns the value of field 'Content-Length' as an integer, or nil if there is no such field; see Content-Length request header:

res = Net::HTTP.get_response(hostname, '/nosuch/1')
res.content_length # => 2
res = Net::HTTP.get_response(hostname, '/todos/1')
res.content_length # => nil

Sets the value of field 'Content-Length' to the given numeric; see Content-Length response header:

_uri = uri.dup
hostname = _uri.hostname           # => "jsonplaceholder.typicode.com"
_uri.path = '/posts'               # => "/posts"
req = Net::HTTP::Post.new(_uri)    # => #<Net::HTTP::Post POST>
req.body = '{"title": "foo","body": "bar","userId": 1}'
req.content_length = req.body.size # => 42
req.content_type = 'application/json'
res = Net::HTTP.start(hostname) do |http|
  http.request(req)
end # => #<Net::HTTPCreated 201 Created readbody=true>

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

Returns the node id for the given backtrace location.

rescue =>  e
  loc = e.backtrace_locations.first

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\">"

Returns true if the given instance variable is defined in obj. 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_defined?(:@a)    #=> true
fred.instance_variable_defined?("@b")   #=> true
fred.instance_variable_defined?("@c")   #=> false
