Looks for a gem dependency file at path and activates the gems in the file if found. If the file is not found an ArgumentError is raised.

If path is not given the RUBYGEMS_GEMDEPS environment variable is used, but if no file is found no exception is raised.

If ‘-’ is given for path RubyGems searches up from the current working directory for gem dependency files (gem.deps.rb, Gemfile, Isolate) and activates the gems in the first one found.

You can run this automatically when rubygems starts. To enable, set the RUBYGEMS_GEMDEPS environment variable to either the path of your gem dependencies file or “-” to auto-discover in parent directories.

NOTE: Enabling automatic discovery on multiuser systems can lead to execution of arbitrary code when used from directories outside your control.

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

@!visibility private

Sends “close notify” to the peer and tries to shut down the SSL connection gracefully.

If sync_close is set to true, the underlying IO is also closed.

Reads length bytes from the SSL connection. If a pre-allocated buffer is provided the data will be written into it.

Writes string to the SSL connection.

Calls block once for each element in self, passing that element as parameter asn1. If no block is given, an enumerator is returned instead.

Example

asn1_ary.each do |asn1|
  puts asn1
end
