Search through all unresolved deps and sub-dependencies and return specs that contain the file matching path.

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 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 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 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

Execute the provided block, but preserve the rounding mode

BigDecimal.save_rounding_mode do
  BigDecimal.mode(BigDecimal::ROUND_MODE, :up)
  puts BigDecimal.mode(BigDecimal::ROUND_MODE)
end

For use with the BigDecimal::ROUND_*

See BigDecimal.mode

Invoked as a callback whenever a singleton method is added to the receiver.

module Chatty
  def Chatty.singleton_method_added(id)
    puts "Adding #{id.id2name}"
  end
  def self.one()     end
  def two()          end
  def Chatty.three() end
end

produces:

Adding singleton_method_added
Adding one
Adding three

Invoked as a callback whenever a singleton method is removed from the receiver.

module Chatty
  def Chatty.singleton_method_removed(id)
    puts "Removing #{id.id2name}"
  end
  def self.one()     end
  def two()          end
  def Chatty.three() end
  class << self
    remove_method :three
    remove_method :one
  end
end

produces:

Removing three
Removing one

Checks for a method provided by this the delegate object by forwarding the call through _getobj_.

Returns true if a local variable symbol exists.

def foo
  a = 1
  binding.local_variable_defined?(:a) #=> true
  binding.local_variable_defined?(:b) #=> false
end

This method is the short version of the following code:

binding.eval("defined?(#{symbol}) == 'local-variable'")

Raises PStore::Error if the calling code is not in a PStore#transaction or if the code is in a read-only PStore#transaction.

The block passed to this method will be called just before running the RDoc generator. It is allowed to modify RDoc::Task attributes inside the block.

Returns the last win32 Error of the current executing Thread or nil if none

Sets the last win32 Error of the current executing Thread to error

For debugging the Ruby/OpenSSL library. Calls CRYPTO_mem_leaks_fp(stderr). Prints detected memory leaks to standard error. This cleans the global state up thus you cannot use any methods of the library after calling this.

Returns true if leaks detected, false otherwise.

This is available only when built with a capable OpenSSL and –enable-debug configure option.

Example

OpenSSL.mem_check_start
NOT_GCED = OpenSSL::PKey::RSA.new(256)

END {
  GC.start
  OpenSSL.print_mem_leaks # will print the leakage
}

Specifies a Proc object proc to determine if a character in the user’s input is escaped. It should take the user’s input and the index of the character in question as input, and return a boolean (true if the specified character is escaped).

Readline will only call this proc with characters specified in completer_quote_characters, to discover if they indicate the end of a quoted argument, or characters specified in completer_word_break_characters, to discover if they indicate a break between arguments.

If completer_quote_characters is not set, or if the user input doesn’t contain one of the completer_quote_characters or a ++ character, Readline will not attempt to use this proc at all.

Raises ArgumentError if proc does not respond to the call method.
