Results for: "gsub"

Returns true if the set is a superset of the given set.

sym.succ

Same as sym.to_s.succ.intern.

Returns the superclass of class, or nil.

File.superclass          #=> IO
IO.superclass            #=> Object
Object.superclass        #=> BasicObject
class Foo; end
class Bar < Foo; end
Bar.superclass           #=> Foo

Returns nil when the given class does not have a parent class:

BasicObject.superclass   #=> nil

Executes the generated ERB code to produce a completed template, returning the results of that code. (See ERB::new for details on how this process can be affected by safe_level.)

b accepts a Binding object which is used to set the context of code evaluation.

Returns the successor to the ipaddr.

Puts option summary into to and returns to. Yields each line if a block is given.

to

Output destination, which must have method <<. Defaults to [].

width

Width of left side, defaults to @summary_width.

max

Maximum length allowed for left side, defaults to width - 1.

indent

Indentation, defaults to @summary_indent.

Returns the sum of elements in an Enumerable.

If a block is given, the block is applied to each element before addition.

If enum is empty, it returns init.

For example:

{ 1 => 10, 2 => 20 }.sum {|k, v| k * v }  #=> 50
(1..10).sum                               #=> 55
(1..10).sum {|v| v * 2 }                  #=> 110
('a'..'z').sum                            #=> TypeError

This method can be used for non-numeric objects by explicit init argument.

{ 1 => 10, 2 => 20 }.sum([])                   #=> [1, 10, 2, 20]
"a\nb\nc".each_line.lazy.map(&:chomp).sum("")  #=> "abc"

If the method is applied to an Integer range without a block, the sum is not done by iteration, but instead using Gauss’s summation formula.

Enumerable#sum method may not respect method redefinition of “+” methods such as Integer#+, or “each” methods such as Range#each.

Returns a hash that contains filename as key and coverage array as value. If clear is true, it clears the counters to zero. If stop is true, it disables coverage measurement.

Returns a BubbleBabble encoded version of a given string.

Returns whether input encoding is UTF-8 or not.

Returns whether input encoding is UTF-8 or not.

Returns the time used to execute the given block as a Benchmark::Tms object. Takes label option.

require 'benchmark'

n = 1000000

time = Benchmark.measure do
  n.times { a = "1" }
end
puts time

Generates:

0.220000   0.000000   0.220000 (  0.227313)

Returns the time used to execute the given block as a Benchmark::Tms object. Takes label option.

require 'benchmark'

n = 1000000

time = Benchmark.measure do
  n.times { a = "1" }
end
puts time

Generates:

0.220000   0.000000   0.220000 (  0.227313)

The path to the running Ruby interpreter.

Suffixes for require-able paths.

Returns the BubbleBabble encoded hash value of a given string.

Returns the flags of ifaddr.

Produces the summary text. Each line of the summary is yielded to the block (without newline).

sdone

Already summarized short style options keyed hash.

ldone

Already summarized long style options keyed hash.

width

Width of left side (option part). In other words, the right side (description part) starts after width columns.

max

Maximum width of left side -> the options are filled within max columns.

indent

Prefix string indents all summarized lines.

Creates the summary table, passing each line to the block (without newline). The arguments args are passed along to the summarize method which is called on every option.

returns the next pseudo-prime number, and move the internal position forward.

PseudoPrimeGenerator#succ raises NotImplementedError.
