Returns an array of missing elements
For example this:
ExplainSyntax.new(code_lines: lines).missing # => ["}"]
Would indicate that the source is missing a ‘}` character in the source code
Returns an array of missing syntax characters or ‘“end”` or `“keyword”`
left_right.missing # => ["}"]
Returns the maximum size of the queue.
Sets the maximum size of the queue to the given number
.
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
Defines a public singleton method in the receiver. The method parameter can be a Proc
, a Method
or an UnboundMethod
object. If a block is specified, it is used as the method body. If a block or a method has parameters, they’re used as method parameters.
class A class << self def class_name to_s end end end A.define_singleton_method(:who_am_i) do "I am: #{class_name}" end A.who_am_i # ==> "I am: A" guy = "Bob" guy.define_singleton_method(:hello) { "#{self}: Hello there!" } guy.hello #=> "Bob: Hello there!" chris = "Chris" chris.define_singleton_method(:greet) {|greeting| "#{greeting}, I'm Chris!" } chris.greet("Hi") #=> "Hi, I'm Chris!"
DO NOT USE THIS DIRECTLY.
Hook method to return whether the obj can respond to id method or not.
When the method name parameter is given as a string, the string is converted to a symbol.
See respond_to?
, and the example of BasicObject
.
Returns a list of the undefined instance methods defined in mod. The undefined methods of any ancestors are not included.
Invoked as a callback whenever a singleton method is undefined in the receiver.
module Chatty def Chatty.singleton_method_undefined(id) puts "Undefining #{id.id2name}" end def Chatty.one() end class << self undef_method(:one) end end
produces:
Undefining one
Checks for a method provided by this the delegate object by forwarding the call through _getobj_.
Called when a map starts.
anchor
is the anchor associated with the map or nil
. tag
is the tag associated with the map or nil
. implicit
is a boolean indicating whether or not the map was implicitly started. style
is an integer indicating the mapping style.
See the constants in Psych::Nodes::Mapping
for the possible values of style
.
Here is a YAML
document that exercises most of the possible ways this method can be called:
--- k: !!map { hello: world } v: &pewpew hello: world
The above YAML
document consists of three maps, an outer map that contains two inner maps. Below is a matrix of the parameters sent in order to represent these three maps:
# anchor tag implicit style [nil, nil, true, 1 ] [nil, "tag:yaml.org,2002:map", false, 2 ] ["pewpew", nil, true, 1 ]
Called when a map ends
Start emitting a YAML
map with anchor
, tag
, an implicit
start and end, and style
.
Returns the minor part of File_Stat#dev
or nil
.
File.stat("/dev/fd1").dev_minor #=> 1 File.stat("/dev/tty").dev_minor #=> 0
Returns the minor part of File_Stat#rdev
or nil
.
File.stat("/dev/fd1").rdev_minor #=> 1 File.stat("/dev/tty").rdev_minor #=> 0
Sets the maximum number of times to retry an idempotent request in case of Net::ReadTimeout, IOError
, EOFError
, Errno::ECONNRESET, Errno::ECONNABORTED, Errno::EPIPE, OpenSSL::SSL::SSLError
, Timeout::Error
. The initial value is 1.
Argument retries
must be a non-negative numeric value:
http = Net::HTTP.new(hostname) http.max_retries = 2 # => 2 http.max_retries # => 2

Binary search through the offsets to find the line number for the given byte offset.
Walk the tree and mark nodes that are on a new line, loosely emulating the behavior of CRuby’s ‘:line` tracepoint event.
