Services the request req which will fill in the response res. See WEBrick::HTTPServlet::AbstractServlet#service for details.
Services req and fills in res
Converts version into an HTTPVersion
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.
Creates a class to wrap the C union described by signature.
MyUnion = union ['int i', 'char c']
Set all the parameters.
Returns collection of supported makers
Calls say with msg or the results of the block if really_verbose is true.
Tries to convert obj into an array, using to_ary method. Returns the converted array or nil if obj cannot be converted for any reason. This method can be used to check if an argument is an array.
Array.try_convert([1]) #=> [1] Array.try_convert("1") #=> nil if tmp = Array.try_convert(arg) # the argument is an array elsif tmp = String.try_convert(arg) # the argument is a string end
Replaces the contents of self with the contents of other_ary, truncating or expanding if necessary.
a = [ "a", "b", "c", "d", "e" ] a.replace([ "x", "y", "z" ]) #=> ["x", "y", "z"] a #=> ["x", "y", "z"]
By using binary search, finds an index of a value from this array which meets the given condition in O(log n) where n is the size of the array.
It supports two modes, depending on the nature of the block and they are exactly the same as in the case of bsearch method with the only difference being that this method returns the index of the element instead of the element itself. For more details consult the documentation for bsearch.
Returns the factorization of self.
See Prime#prime_division for more details.
Numerics are immutable values, which should not be copied.
Any attempt to use this method on a Numeric will raise a TypeError.
Try to convert obj into a String, using to_str method. Returns converted string or nil if obj cannot be converted for any reason.
String.try_convert("str") #=> "str" String.try_convert(/re/) #=> nil
Replaces the contents and taintedness of str with the corresponding values in other_str.
s = "hello" #=> "hello" s.replace "world" #=> "world"
Converts a pathname to an absolute pathname. Relative paths are referenced from the current working directory of the process unless dir_string is given, in which case it will be used as the starting point. The given pathname may start with a “~”, which expands to the process owner’s home directory (the environment variable HOME must be set correctly). “~user” expands to the named user’s home directory.
File.expand_path("~oracle/bin") #=> "/home/oracle/bin"
A simple example of using dir_string is as follows.
File.expand_path("ruby", "/usr/bin") #=> "/usr/bin/ruby"
A more complex example which also resolves parent directory is as follows. Suppose we are in bin/mygem and want the absolute path of lib/mygem.rb.
File.expand_path("../../lib/mygem.rb", __FILE__) #=> ".../path/to/project/lib/mygem.rb"
So first it resolves the parent of __FILE__, that is bin/, then go to the parent, the root of the project and appends lib/mygem.rb.
Returns whether ASCII-compatible or not.
Encoding::UTF_8.ascii_compatible? #=> true Encoding::UTF_16BE.ascii_compatible? #=> false
