Escapes ‘user:password’ v based on RFC 1738 section 3.1.
Private setter for extensions val.
Private setter for headers v.
Constructs the default Hash of patterns.
possible opt elements:
hash form: :partial_input => true # source buffer may be part of larger source :after_output => true # stop conversion after output before input integer form: Encoding::Converter::PARTIAL_INPUT Encoding::Converter::AFTER_OUTPUT
possible results:
:invalid_byte_sequence :incomplete_input :undefined_conversion :after_output :destination_buffer_full :source_buffer_empty :finished
primitive_convert converts source_buffer into destination_buffer.
source_buffer should be a string or nil. nil means an empty string.
destination_buffer should be a string.
destination_byteoffset should be an integer or nil. nil means the end of destination_buffer. If it is omitted, nil is assumed.
destination_bytesize should be an integer or nil. nil means unlimited. If it is omitted, nil is assumed.
opt should be nil, a hash or an integer. nil means no flags. If it is omitted, nil is assumed.
primitive_convert converts the content of source_buffer from beginning and store the result into destination_buffer.
destination_byteoffset and destination_bytesize specify the region which the converted result is stored. destination_byteoffset specifies the start position in destination_buffer in bytes. If destination_byteoffset is nil, destination_buffer.bytesize is used for appending the result. destination_bytesize specifies maximum number of bytes. If destination_bytesize is nil, destination size is unlimited. After conversion, destination_buffer is resized to destination_byteoffset + actually produced number of bytes. Also destination_buffer’s encoding is set to destination_encoding.
primitive_convert drops the converted part of source_buffer. the dropped part is converted in destination_buffer or buffered in Encoding::Converter object.
primitive_convert stops conversion when one of following condition met.
invalid byte sequence found in source buffer (:invalid_byte_sequence) primitive_errinfo and last_error methods returns the detail of the error.
unexpected end of source buffer (:incomplete_input) this occur only when :partial_input is not specified. primitive_errinfo and last_error methods returns the detail of the error.
character not representable in output encoding (:undefined_conversion) primitive_errinfo and last_error methods returns the detail of the error.
after some output is generated, before input is done (:after_output) this occur only when :after_output is specified.
destination buffer is full (:destination_buffer_full) this occur only when destination_bytesize is non-nil.
source buffer is empty (:source_buffer_empty) this occur only when :partial_input is specified.
conversion is finished (:finished)
example:
ec = Encoding::Converter.new("UTF-8", "UTF-16BE") ret = ec.primitive_convert(src="pi", dst="", nil, 100) p [ret, src, dst] #=> [:finished, "", "\x00p\x00i"] ec = Encoding::Converter.new("UTF-8", "UTF-16BE") ret = ec.primitive_convert(src="pi", dst="", nil, 1) p [ret, src, dst] #=> [:destination_buffer_full, "i", "\x00"] ret = ec.primitive_convert(src, dst="", nil, 1) p [ret, src, dst] #=> [:destination_buffer_full, "", "p"] ret = ec.primitive_convert(src, dst="", nil, 1) p [ret, src, dst] #=> [:destination_buffer_full, "", "\x00"] ret = ec.primitive_convert(src, dst="", nil, 1) p [ret, src, dst] #=> [:finished, "", "i"]

Parses multipart form elements according to
http://www.w3.org/TR/html401/interact/forms.html#h-17.13.4.2
Returns a hash of multipart form parameters with bodies of type StringIO or Tempfile depending on whether the multipart form element exceeds 10 KB
params[name => body]
Generate a Form element with multipart encoding as a String.
Multipart encoding is used for forms that include file uploads.
action is the action to perform. enctype is the encoding type, which defaults to “multipart/form-data”.
Alternatively, the attributes can be specified as a hash.
multipart_form{ "string" } # <FORM METHOD="post" ENCTYPE="multipart/form-data">string</FORM> multipart_form("url") { "string" } # <FORM METHOD="post" ACTION="url" ENCTYPE="multipart/form-data">string</FORM>
Create a new ParenthesesNode node.
Create a new RationalNode node.
Retrieve the value of one of the ParameterFlags flags.
The default location object that gets attached to nodes if no location is specified, which uses the given source.
Message to promote available RubyGems update with related gem update command.
Gets the global do_not_reverse_lookup flag.
BasicSocket.do_not_reverse_lookup #=> false
Sets the global do_not_reverse_lookup flag.
The flag is used for initial value of do_not_reverse_lookup for each socket.
s1 = TCPSocket.new("localhost", 80) p s1.do_not_reverse_lookup #=> true BasicSocket.do_not_reverse_lookup = false s2 = TCPSocket.new("localhost", 80) p s2.do_not_reverse_lookup #=> false p s1.do_not_reverse_lookup #=> true
Gets the do_not_reverse_lookup flag of basicsocket.
require 'socket' BasicSocket.do_not_reverse_lookup = false TCPSocket.open("www.ruby-lang.org", 80) {|sock| p sock.do_not_reverse_lookup #=> false } BasicSocket.do_not_reverse_lookup = true TCPSocket.open("www.ruby-lang.org", 80) {|sock| p sock.do_not_reverse_lookup #=> true }
Sets the do_not_reverse_lookup flag of basicsocket.
TCPSocket.open("www.ruby-lang.org", 80) {|sock| p sock.do_not_reverse_lookup #=> true p sock.peeraddr #=> ["AF_INET", 80, "221.186.184.68", "221.186.184.68"] sock.do_not_reverse_lookup = false p sock.peeraddr #=> ["AF_INET", 80, "carbon.ruby-lang.org", "54.163.249.195"] }
Constant time memory comparison for fixed length strings, such as results of HMAC calculations.
Returns true if the strings are identical, false if they are of the same length but not identical. If the length is different, ArgumentError is raised.
The index to insert activated gem paths into the $LOAD_PATH. The activated gem’s paths are inserted before site lib directory by default.
The iterator version of the strongly_connected_components method. obj.each_strongly_connected_component is similar to obj.strongly_connected_components.each, but modification of obj during the iteration may lead to unexpected results.
each_strongly_connected_component returns nil.

The iterator version of the TSort.strongly_connected_components method.
The graph is represented by each_node and each_child. each_node should have call method which yields for each node in the graph. each_child should have call method which takes a node argument and yields for each child node.
