Returns the generator of the group.

See the OpenSSL documentation for EC_GROUP_get0_generator()

Returns the concatenated string from strings.

The error message for the missing dependency, including the specifications that had this dependency.

Re-composes a prime factorization and returns the product.

See Prime#int_from_prime_division for more details.

Passes each grapheme cluster in str to the given block, or returns an enumerator if no block is given. Unlike String#each_char, this enumerates by grapheme clusters defined by Unicode Standard Annex #29 unicode.org/reports/tr29/

"a\u0300".each_char.to_a.size #=> 2
"a\u0300".each_grapheme_cluster.to_a.size #=> 1

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.

Iterates the given block for each element with an arbitrary object, obj, and returns obj

If no block is given, returns a new Enumerator.

Example

to_three = Enumerator.new do |y|
  3.times do |x|
    y << x
  end
end

to_three_with_string = to_three.with_object("foo")
to_three_with_string.each do |x,string|
  puts "#{string}: #{x}"
end

# => foo: 0
# => foo: 1
# => foo: 2

Returns the Ruby source filename and line number containing the definition of the constant specified. If the named constant is not found, nil is returned. If the constant is found, but its source location can not be extracted (constant is defined in C code), empty array is returned.

inherit specifies whether to lookup in mod.ancestors (true by default).

# test.rb:
class A         # line 1
  C1 = 1
  C2 = 2
end

module M        # line 6
  C3 = 3
end

class B < A     # line 10
  include M
  C4 = 4
end

class A # continuation of A definition
  C2 = 8 # constant redefinition; warned yet allowed
end

p B.const_source_location('C4')           # => ["test.rb", 12]
p B.const_source_location('C3')           # => ["test.rb", 7]
p B.const_source_location('C1')           # => ["test.rb", 2]

p B.const_source_location('C3', false)    # => nil  -- don't lookup in ancestors

p A.const_source_location('C2')           # => ["test.rb", 16] -- actual (last) definition place

p Object.const_source_location('B')       # => ["test.rb", 10] -- top-level constant could be looked through Object
p Object.const_source_location('A')       # => ["test.rb", 1] -- class reopening is NOT considered new definition

p B.const_source_location('A')            # => ["test.rb", 1]  -- because Object is in ancestors
p M.const_source_location('A')            # => ["test.rb", 1]  -- Object is not ancestor, but additionally checked for modules

p Object.const_source_location('A::C1')   # => ["test.rb", 2]  -- nesting is supported
p Object.const_source_location('String')  # => []  -- constant is defined in C code

Makes the set compare its elements by their identity and returns self. This method may not be supported by all subclasses of Set.

Returns true if the set will compare its elements by their identity. Also see Set#compare_by_identity.

Packs port and host as an AF_INET/AF_INET6 sockaddr string.

Socket.sockaddr_in(80, "127.0.0.1")
#=> "\x02\x00\x00P\x7F\x00\x00\x01\x00\x00\x00\x00\x00\x00\x00\x00"

Socket.sockaddr_in(80, "::1")
#=> "\n\x00\x00P\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x01\x00\x00\x00\x00"

Unpacks sockaddr into port and ip_address.

sockaddr should be a string or an addrinfo for AF_INET/AF_INET6.

sockaddr = Socket.sockaddr_in(80, "127.0.0.1")
p sockaddr #=> "\x02\x00\x00P\x7F\x00\x00\x01\x00\x00\x00\x00\x00\x00\x00\x00"
p Socket.unpack_sockaddr_in(sockaddr) #=> [80, "127.0.0.1"]

Packs path as an AF_UNIX sockaddr string.

Socket.sockaddr_un("/tmp/sock") #=> "\x01\x00/tmp/sock\x00\x00..."

Unpacks sockaddr into path.

sockaddr should be a string or an addrinfo for AF_UNIX.

sockaddr = Socket.sockaddr_un("/tmp/sock")
p Socket.unpack_sockaddr_un(sockaddr) #=> "/tmp/sock"

Returns the array of WIN32OLE_TYPE object which is implemented by the WIN32OLE_TYPE object.

tobj = WIN32OLE_TYPE.new('Microsoft Excel 9.0 Object Library', 'Worksheet')
p tobj.implemented_ole_types # => [_Worksheet, DocEvents]

Sets self to consider only identity in comparing keys; two keys are considered the same only if they are the same object; returns self.

By default, these two object are considered to be the same key, so s1 will overwrite s0:

s0 = 'x'
s1 = 'x'
h = {}
h.compare_by_identity? # => false
h[s0] = 0
h[s1] = 1
h # => {"x"=>1}

After calling #compare_by_identity, the keys are considered to be different, and therefore do not overwrite each other:

h = {}
h.compare_by_identity # => {}
h.compare_by_identity? # => true
h[s0] = 0
h[s1] = 1
h # => {"x"=>0, "x"=>1}

Returns true if compare_by_identity has been called, false otherwise.

Prints all threads in @thread_list to @stdout. Returns a sorted array of values from the @thread_list hash.

While in the debugger you can list all of the threads with: DEBUGGER__.thread_list_all

(rdb:1) DEBUGGER__.thread_list_all
+1 #<Thread:0x007fb2320c03f0 run> debug_me.rb.rb:3
 2 #<Thread:0x007fb23218a538 debug_me.rb.rb:3 sleep>
 3 #<Thread:0x007fb23218b0f0 debug_me.rb.rb:3 sleep>
[1, 2, 3]

Your current thread is indicated by a +

Additionally you can list all threads with th l

(rdb:1) th l
 +1 #<Thread:0x007f99328c0410 run>  debug_me.rb:3
  2 #<Thread:0x007f9932938230 debug_me.rb:3 sleep> debug_me.rb:3
