...tsort はトポロジカルソートと強連結成分に関するモジュールを提供します。
=== Example
//emlist[][ruby]{
require 'tsort'
class Hash
include TSort
alias tsort_each_node each_key
def tsort_each_child(node, &block)
fetch(node).each(&block)
end
end
{1=>[2, 3],......=>[]}.tsort
#=> [3, 2, 1, 4]
{1=>[2], 2=>[3, 4], 3=>[2], 4=>[]}.strongly_connected_components
#=> [[4], [2, 3], [1]]
//}
=== より現実的な例
非常に単純な `make' に似たツールは以下のように実装できます。
//emlist[][ruby]{
require 'tsort'
class Make
def initialize......lock)
triple = [outputs, inputs, block]
outputs.each {|f| @dep[f] = [triple]}
@dep[triple] = inputs
end
def build(target)
each_strongly_connected_component_from(target) {|ns|
if ns.length != 1
fs = ns.delete_if {|n| Array === n}
