Unaliases the given alias command.
check the user and password.
If password is not provided, then user is split, using URI::Generic.split_userinfo, to pull user and +password.
see also URI::Generic.check_user, URI::Generic.check_password
protect setter for the user component, and password if available. (with validation)
see also URI::Generic.userinfo=
returns the userinfo ui as user, password if properly formatted as ‘user:password’
returns a proxy URI. The proxy URI is obtained from environment variables such as http_proxy, ftp_proxy, no_proxy, etc. If there is no proper proxy, nil is returned.
Note that capitalized variables (HTTP_PROXY, FTP_PROXY, NO_PROXY, etc.) are examined too.
But http_proxy and HTTP_PROXY is treated specially under CGI environment. It’s because HTTP_PROXY may be set by Proxy: header. So HTTP_PROXY is not used. http_proxy is not used too if the variable is case insensitive. CGI_HTTP_PROXY can be used instead.
Returns the RFC822 e-mail text equivalent of the URL, as a String.
Example:
require 'uri' uri = URI.parse("mailto:ruby-list@ruby-lang.org?Subject=subscribe&cc=myaddr") uri.to_mailtext # => "To: ruby-list@ruby-lang.org\nSubject: subscribe\nCc: myaddr\n\n\n"
returns Regexp that is default self.regexp, unless schemes is provided. Then it is a Regexp.union with self.pattern
Constructs the default Hash of patterns
Constructs the default Hash of Regexp’s
returns Regexp that is default self.regexp, unless schemes is provided. Then it is a Regexp.union with self.pattern
Constructs the default Hash of patterns
Constructs the default Hash of Regexp’s
The response’s HTTP status line
Adds the introspection handlers "system.listMethods", "system.methodSignature" and "system.methodHelp", where only the first one works.
Returns the number of threads waiting on the queue.
Returns the number of threads waiting on the queue.
Returns the source encoding as an encoding object.
Note that the result may not be equal to the source encoding of the encoding converter if the conversion has multiple steps.
ec = Encoding::Converter.new("ISO-8859-1", "EUC-JP") # ISO-8859-1 -> UTF-8 -> EUC-JP begin ec.convert("\xa0") # NO-BREAK SPACE, which is available in UTF-8 but not in EUC-JP. rescue Encoding::UndefinedConversionError p $!.source_encoding #=> #<Encoding:UTF-8> p $!.destination_encoding #=> #<Encoding:EUC-JP> p $!.source_encoding_name #=> "UTF-8" p $!.destination_encoding_name #=> "EUC-JP" end
Returns the source encoding as an encoding object.
Note that the result may not be equal to the source encoding of the encoding converter if the conversion has multiple steps.
ec = Encoding::Converter.new("ISO-8859-1", "EUC-JP") # ISO-8859-1 -> UTF-8 -> EUC-JP begin ec.convert("\xa0") # NO-BREAK SPACE, which is available in UTF-8 but not in EUC-JP. rescue Encoding::UndefinedConversionError p $!.source_encoding #=> #<Encoding:UTF-8> p $!.destination_encoding #=> #<Encoding:EUC-JP> p $!.source_encoding_name #=> "UTF-8" p $!.destination_encoding_name #=> "EUC-JP" end
Returns the bytes to be read again when Encoding::InvalidByteSequenceError occurs.
Returns the corresponding ASCII compatible encoding.
Returns nil if the argument is an ASCII compatible encoding.
“corresponding ASCII compatible encoding” is an ASCII compatible encoding which can represents exactly the same characters as the given ASCII incompatible encoding. So, no conversion undefined error occurs when converting between the two encodings.
Encoding::Converter.asciicompat_encoding("ISO-2022-JP") #=> #<Encoding:stateless-ISO-2022-JP> Encoding::Converter.asciicompat_encoding("UTF-16BE") #=> #<Encoding:UTF-8> Encoding::Converter.asciicompat_encoding("UTF-8") #=> nil
Returns the source encoding as an Encoding object.
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"]
