The path to standard location of the user’s cache directory.

Default gem load path

Default options for gem commands for Ruby implementers.

The options here should be structured as an array of string “gem” command names as keys and a string of the default options as values.

Example:

def self.platform_defaults

{
    'install' => '--no-rdoc --no-ri --env-shebang',
    'update' => '--no-rdoc --no-ri --env-shebang'
}

end

The iterator version of the tsort method. obj.tsort_each is similar to obj.tsort.each, but modification of obj during the iteration may lead to unexpected results.

tsort_each returns nil. If there is a cycle, TSort::Cyclic is raised.

class G
  include TSort
  def initialize(g)
    @g = g
  end
  def tsort_each_child(n, &b) @g[n].each(&b) end
  def tsort_each_node(&b) @g.each_key(&b) end
end

graph = G.new({1=>[2, 3], 2=>[4], 3=>[2, 4], 4=>[]})
graph.tsort_each {|n| p n }
#=> 4
#   2
#   3
#   1

The iterator version of the TSort.tsort method.

The graph is represented by each_node and each_child. each_node should have call method which yields for each node in the graph. each_child should have call method which takes a node argument and yields for each child node.

g = {1=>[2, 3], 2=>[4], 3=>[2, 4], 4=>[]}
each_node = lambda {|&b| g.each_key(&b) }
each_child = lambda {|n, &b| g[n].each(&b) }
TSort.tsort_each(each_node, each_child) {|n| p n }
#=> 4
#   2
#   3
#   1

Returns the status of the last executed child process in the current thread.

Process.wait Process.spawn("ruby", "-e", "exit 13")
Process.last_status   #=> #<Process::Status: pid 4825 exit 13>

If no child process has ever been executed in the current thread, this returns nil.

Process.last_status   #=> nil

@!visibility private

Returns AST nodes under this one. Each kind of node has different children, depending on what kind of node it is.

The returned array may contain other nodes or nil.

Creates a new DH instance from scratch by generating random parameters and a key pair.

size

The desired key size in bits.

generator

The generator.

Indicates whether this DH instance has a private key associated with it or not. The private key may be retrieved with DH#priv_key.

Creates a new DSA instance by generating a private/public key pair from scratch.

See also OpenSSL::PKey.generate_parameters and OpenSSL::PKey.generate_key.

size

The desired key size in bits.

Indicates whether this DSA instance has a private key associated with it or not. The private key may be retrieved with DSA#private_key.

Creates a new EC instance with a new random private and public key.

Returns whether this EC instance has a private key. The private key (BN) can be retrieved with EC#private_key.
