Finishes the digest and returns the resulting hash value.

This method is overridden by each implementation subclass and often made private, because some of those subclasses may leave internal data uninitialized. Do not call this method from outside. Use digest!() instead, which ensures that internal data be reset for security reasons.

Creates a printable version of the digest object.

Reads lines from the stream which are separated by eol.

Reads a line from the stream which is separated by eol.

Raises EOFError if at end of file.

Writes args to the stream.

See IO#print for full details.

Formats and writes to the stream converting parameters under control of the format string.

See Kernel#sprintf for format string details.

Generate a submit button Input element, as a String.

value is the text to display on the button. name is the name of the input.

Alternatively, the attributes can be specified as a hash.

submit
  # <INPUT TYPE="submit">

submit("ok")
  # <INPUT TYPE="submit" VALUE="ok">

submit("ok", "button1")
  # <INPUT TYPE="submit" VALUE="ok" NAME="button1">

submit("VALUE" => "ok", "NAME" => "button1", "ID" => "foo")
  # <INPUT TYPE="submit" VALUE="ok" NAME="button1" ID="foo">

Create a new repository for the given string.

A Zlib::Inflate#inflate wrapper

Create parser string nodes from a single prism node. The parser gem “glues” strings together when a line continuation is encountered.

Replaces the elements of self with the elements of other_array, which must be an array-convertible object; returns self:

a = ['a', 'b', 'c']   # => ["a", "b", "c"]
a.replace(['d', 'e']) # => ["d", "e"]

With a block given, iterates over the elements of self, passing each array index to the block; returns self:

a = [:foo, 'bar', 2]
a.each_index {|index|  puts "#{index} #{a[index]}" }

Output:

0 foo
1 bar
2 2

Allows the array to be modified during iteration:

a = [:foo, 'bar', 2]
a.each_index {|index| puts index; a.clear if index > 0 }
a # => []

Output:

0
1

With no block given, returns a new Enumerator.

With a block given, calls the block with each repeated combination of length size of the elements of self; each combination is an array; returns self. The order of the combinations is indeterminate.

If a positive integer argument size is given, calls the block with each size-tuple repeated combination of the elements of self. The number of combinations is (size+1)(size+2)/2.

Examples:

• size is 1:

  c = []
  [0, 1, 2].repeated_combination(1) {|combination| c.push(combination) }
  c # => [[0], [1], [2]]
  

• size is 2:

  c = []
  [0, 1, 2].repeated_combination(2) {|combination| c.push(combination) }
  c # => [[0, 0], [0, 1], [0, 2], [1, 1], [1, 2], [2, 2]]
  

If size is zero, calls the block once with an empty array.

If size is negative, does not call the block:

[0, 1, 2].repeated_combination(-1) {|combination| fail 'Cannot happen' }

With no block given, returns a new Enumerator.

Returns the integer index of the element from self found by a binary search, or nil if the search found no suitable element.

See Binary Searching.

Related: see Methods for Fetching.

Returns self (which is already an Integer).

Returns self as an integer; converts using method to_i in the derived class.

Of the Core and Standard Library classes, only Rational and Complex use this implementation.

Examples:

Rational(1, 2).to_int # => 0
Rational(2, 1).to_int # => 2
Complex(2, 0).to_int  # => 2
Complex(2, 1).to_int  # Raises RangeError (non-zero imaginary part)

Replaces the contents of self with the contents of other_string:

s = 'foo'        # => "foo"
s.replace('bar') # => "bar"
