Generate a sequence of radio button Input elements, as a String.

This works the same as checkbox_group(). However, it is not valid to have more than one radiobutton in a group checked.

radio_group("name", "foo", "bar", "baz")
  # <INPUT TYPE="radio" NAME="name" VALUE="foo">foo
  # <INPUT TYPE="radio" NAME="name" VALUE="bar">bar
  # <INPUT TYPE="radio" NAME="name" VALUE="baz">baz

radio_group("name", ["foo"], ["bar", true], "baz")
  # <INPUT TYPE="radio" NAME="name" VALUE="foo">foo
  # <INPUT TYPE="radio" CHECKED NAME="name" VALUE="bar">bar
  # <INPUT TYPE="radio" NAME="name" VALUE="baz">baz

radio_group("name", ["1", "Foo"], ["2", "Bar", true], "Baz")
  # <INPUT TYPE="radio" NAME="name" VALUE="1">Foo
  # <INPUT TYPE="radio" CHECKED NAME="name" VALUE="2">Bar
  # <INPUT TYPE="radio" NAME="name" VALUE="Baz">Baz

radio_group("NAME" => "name",
              "VALUES" => ["foo", "bar", "baz"])

radio_group("NAME" => "name",
              "VALUES" => [["foo"], ["bar", true], "baz"])

radio_group("NAME" => "name",
              "VALUES" => [["1", "Foo"], ["2", "Bar", true], "Baz"])

returns a Time that represents the Last-Modified field.

Returns a list of encodings in Content-Encoding field as an array of strings.

The encodings are downcased for canonicalization.

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

The number of bytes that are immediately available for reading.

The version requirement for this dependency request

Returns true, if circular data structures should be checked, otherwise returns false.

Checks if ios starts with a BOM, and then consumes it and sets the external encoding. Returns the result encoding if found, or nil. If ios is not binmode or its encoding has been set already, an exception will be raised.

File.write("bom.txt", "\u{FEFF}abc")
ios = File.open("bom.txt", "rb")
ios.set_encoding_by_bom    #=>  #<Encoding:UTF-8>

File.write("nobom.txt", "abc")
ios = File.open("nobom.txt", "rb")
ios.set_encoding_by_bom    #=>  nil

Re-composes a prime factorization and returns the product.

For the decomposition:

[[p_1, e_1], [p_2, e_2], ..., [p_n, e_n]],

it returns:

p_1**e_1 * p_2**e_2 * ... * p_n**e_n.

Parameters

pd

Array of pairs of integers. Each pair consists of a prime number – a prime factor – and a natural number – its exponent (multiplicity).

Example

Prime.int_from_prime_division([[3, 2], [5, 1]])  #=> 45
3**2 * 5                                         #=> 45

Return true if this spec can require file.
