Returns true if URI does not have a scheme (e.g. http:// or https://) specified.
str
String to search
schemes
Patterns to apply to str
Attempts to parse and merge a set of URIs. If no block given, then returns the result, else it calls block for each element in result.
See also URI::Parser.make_regexp.
Removes escapes from str.
Converts the contents of the database to an in-memory Hash, then calls Hash#reject with the specified code block, returning a new Hash.
Returns a string representation of self:
system("false") $?.inspect # => "#<Process::Status: pid 1303494 exit 1>"
Invoked to wake up Fiber previously blocked with block (for example, Mutex#lock calls block and Mutex#unlock calls unblock). The scheduler should use the fiber parameter to understand which fiber is unblocked.
blocker is what was awaited for, but it is informational only (for debugging and logging), and it is not guaranteed to be the same value as the blocker for block.
Releases the lock. Raises ThreadError if mutex wasn’t locked by the current thread.
Returns a printable version of ec
ec = Encoding::Converter.new("iso-8859-1", "utf-8") puts ec.inspect #=> #<Encoding::Converter: ISO-8859-1 to UTF-8>
Returns the conversion path of ec.
The result is an array of conversions.
ec = Encoding::Converter.new("ISO-8859-1", "EUC-JP", crlf_newline: true) p ec.convpath #=> [[#<Encoding:ISO-8859-1>, #<Encoding:UTF-8>], # [#<Encoding:UTF-8>, #<Encoding:EUC-JP>], # "crlf_newline"]
Each element of the array is a pair of encodings or a string. A pair means an encoding conversion. A string means a decorator.
In the above example, [#<Encoding:ISO-8859-1>,
Convert source_string and return destination_string.
source_string is assumed as a part of source. i.e. :partial_input=>true is specified internally. finish method should be used last.
ec = Encoding::Converter.new("utf-8", "euc-jp") puts ec.convert("\u3042").dump #=> "\xA4\xA2" puts ec.finish.dump #=> "" ec = Encoding::Converter.new("euc-jp", "utf-8") puts ec.convert("\xA4").dump #=> "" puts ec.convert("\xA2").dump #=> "\xE3\x81\x82" puts ec.finish.dump #=> "" ec = Encoding::Converter.new("utf-8", "iso-2022-jp") puts ec.convert("\xE3").dump #=> "".force_encoding("ISO-2022-JP") puts ec.convert("\x81").dump #=> "".force_encoding("ISO-2022-JP") puts ec.convert("\x82").dump #=> "\e$B$\"".force_encoding("ISO-2022-JP") puts ec.finish.dump #=> "\e(B".force_encoding("ISO-2022-JP")
If a conversion error occur, Encoding::UndefinedConversionError or Encoding::InvalidByteSequenceError is raised. Encoding::Converter#convert doesn’t supply methods to recover or restart from these exceptions. When you want to handle these conversion errors, use Encoding::Converter#primitive_convert.
Returns true if key is a key in self, otherwise false.
Returns a new String containing informations about the map:
m = ObjectSpace::WeakKeyMap.new m[key] = value m.inspect # => "#<ObjectSpace::WeakKeyMap:0x00000001028dcba8 size=1>"
Returns HTML-unescaped string.
Returns URL-escaped string following RFC 3986.
Returns URL-unescaped string (application/x-www-form-urlencoded).
URL-decode an application/x-www-form-urlencoded string with encoding(optional).
string = CGI.unescape("%27Stop%21%27+said+Fred") # => "'Stop!' said Fred"
URL-encode a string following RFC 3986 Space characters (+“ ”+) are encoded with (+“%20”+)
url_encoded_string = CGI.escapeURIComponent("'Stop!' said Fred") # => "%27Stop%21%27%20said%20Fred"
Unescape a string that has been HTML-escaped
CGI.unescapeHTML("Usage: foo "bar" <baz>") # => "Usage: foo \"bar\" <baz>"
Creates a printable version of the digest object.
Creates a class to wrap the C struct described by signature.
MyStruct = struct ['int i', 'char c']
Reads at most maxlen bytes from the stream. If buf is provided it must reference a string which will receive the data.
See IO#readpartial for full details.
