Results for: "module_function"

Same as XMLRPC::Client#multicall, but returns two parameters instead of raising an XMLRPC::FaultException.

See XMLRPC::Client#call2

Generates a XML-RPC methodResponse document

When is_ret is false then the params array must contain only one element, which is a structure of a fault return-value.

When is_ret is true then a normal return-value of all the given params is created.

Set value as the new date/time component.

Raises an ArgumentError if the given value isn’t between 1 and 12.

Alias for XMLRPC::DateTime#month=.

If a block is provided, returns a new array containing [key, value] pairs for which the block returns true.

Otherwise, same as values_at

Returns whether the form contained multipart/form-data

Undo escaping such as that done by CGI::escapeElement()

print CGI::unescapeElement(
        CGI::escapeHTML('<BR><A HREF="url"></A>'), "A", "IMG")
  # "&lt;BR&gt;<A HREF="url"></A>"

print CGI::unescapeElement(
        CGI::escapeHTML('<BR><A HREF="url"></A>'), ["A", "IMG"])
  # "&lt;BR&gt;<A HREF="url"></A>"

Unicode Normalization

Returns a normalized form of str, using Unicode normalizations NFC, NFD, NFKC, or NFKD. The normalization form used is determined by form, which is any of the four values :nfc, :nfd, :nfkc, or :nfkd. The default is :nfc.

If the string is not in a Unicode Encoding, then an Exception is raised. In this context, ‘Unicode Encoding’ means any of UTF-8, UTF-16BE/LE, and UTF-32BE/LE, as well as GB18030, UCS_2BE, and UCS_4BE. Anything else than UTF-8 is implemented by converting to UTF-8, which makes it slower than UTF-8.

Examples

"a\u0300".unicode_normalize        #=> 'à' (same as "\u00E0")
"a\u0300".unicode_normalize(:nfc)  #=> 'à' (same as "\u00E0")
"\u00E0".unicode_normalize(:nfd)   #=> 'à' (same as "a\u0300")
"\xE0".force_encoding('ISO-8859-1').unicode_normalize(:nfd)
                                   #=> Encoding::CompatibilityError raised

Destructive version of String#unicode_normalize, doing Unicode normalization in place.

Checks whether str is in Unicode normalization form form, which is any of the four values :nfc, :nfd, :nfkc, or :nfkd. The default is :nfc.

If the string is not in a Unicode Encoding, then an Exception is raised. For details, see String#unicode_normalize.

Examples

"a\u0300".unicode_normalized?        #=> false
"a\u0300".unicode_normalized?(:nfd)  #=> true
"\u00E0".unicode_normalized?         #=> true
"\u00E0".unicode_normalized?(:nfd)   #=> false
"\xE0".force_encoding('ISO-8859-1').unicode_normalized?
                                     #=> Encoding::CompatibilityError raised

Changes the encoding to encoding and returns self.

Returns true for a string which encoded correctly.

"\xc2\xa1".force_encoding("UTF-8").valid_encoding?  #=> true
"\xc2".force_encoding("UTF-8").valid_encoding?      #=> false
"\x80".force_encoding("UTF-8").valid_encoding?      #=> false

Returns whether ASCII-compatible or not.

Encoding::UTF_8.ascii_compatible?     #=> true
Encoding::UTF_16BE.ascii_compatible?  #=> false

Returns the singleton class of obj. This method creates a new singleton class if obj does not have one.

If obj is nil, true, or false, it returns NilClass, TrueClass, or FalseClass, respectively. If obj is a Fixnum or a Symbol, it raises a TypeError.

Object.new.singleton_class  #=> #<Class:#<Object:0xb7ce1e24>>
String.singleton_class      #=> #<Class:String>
nil.singleton_class         #=> NilClass

Returns the list of protected methods accessible to obj. If the all parameter is set to false, only those methods in the receiver will be listed.

Returns an array of instance variable names for the receiver. Note that simply defining an accessor does not create the corresponding instance variable.

class Fred
  attr_accessor :a1
  def initialize
    @iv = 3
  end
end
Fred.new.instance_variables   #=> [:@iv]

This method is equivalent to d >> n

This method is equivalent to d << n

Returns the Encoding object that represents the encoding of the file. If io is in write mode and no encoding is specified, returns nil.

Returns the Encoding of the internal string if conversion is specified. Otherwise returns nil.

If single argument is specified, read string from io is tagged with the encoding specified. If encoding is a colon separated two encoding names “A:B”, the read string is converted from encoding A (external encoding) to encoding B (internal encoding), then tagged with B. If two arguments are specified, those must be encoding objects or encoding names, and the first one is the external encoding, and the second one is the internal encoding. If the external encoding and the internal encoding is specified, optional hash argument specify the conversion option.
