The content-length header

Sets the content-length header to len

Mounts proc or block on dir and calls it with a WEBrick::HTTPRequest and WEBrick::HTTPResponse

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>

Returns true if the invalid byte sequence error is caused by premature end of string.

ec = Encoding::Converter.new("EUC-JP", "ISO-8859-1")

begin
  ec.convert("abc\xA1z")
rescue Encoding::InvalidByteSequenceError
  p $!      #=> #<Encoding::InvalidByteSequenceError: "\xA1" followed by "z" on EUC-JP>
  p $!.incomplete_input?    #=> false
end

begin
  ec.convert("abc\xA1")
  ec.finish
rescue Encoding::InvalidByteSequenceError
  p $!      #=> #<Encoding::InvalidByteSequenceError: incomplete "\xA1" on EUC-JP>
  p $!.incomplete_input?    #=> true
end

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.

Synonym for CGI.unescapeElement(str)

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>

A utility method for encoding the String s as a URL.

Returns an Integer object which represents the HTTP Content-Length: header field, or nil if that field was not provided.

This code is based directly on the Text gem implementation Returns a value representing the “cost” of transforming str1 into str2

Remove everything in the DependencyList that matches but doesn’t satisfy items in dependencies (a hash of gem names to arrays of dependencies).

| FUNCTION_NAME ‘(’ ( expr ( ‘,’ expr )* )? ‘)’

Returns the value of the given instance variable, or nil if the instance variable is not set. The @ part of the variable name should be included for regular instance variables. Throws a NameError exception if the supplied symbol is not valid as an instance variable name. String arguments are converted to symbols.

class Fred
  def initialize(p1, p2)
    @a, @b = p1, p2
  end
end
fred = Fred.new('cat', 99)
fred.instance_variable_get(:@a)    #=> "cat"
fred.instance_variable_get("@b")   #=> 99
