Helper method for grabbing elements from document

Like ‘take_while` except when it stops iterating, it also returns the line that caused it to stop

Compile a InstanceVariableWriteNode node

Dispatch enter and leave events for InstanceVariableWriteNode nodes and continue walking the tree.

Copy a InstanceVariableWriteNode node

Create a new InstanceVariableAndWriteNode node.

Create a new InstanceVariableOperatorWriteNode node.

Create a new InstanceVariableOrWriteNode node.

Iterates over strongly connected component in the subgraph reachable from node.

Return value is unspecified.

each_strongly_connected_component_from doesn’t call tsort_each_node.

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.each_strongly_connected_component_from(2) {|scc| p scc }
#=> [4]
#   [2]

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

Iterates over strongly connected components in a graph. The graph is represented by node and each_child.

node is the first node. each_child should have call method which takes a node argument and yields for each child node.

Return value is unspecified.

TSort.each_strongly_connected_component_from is a class method and it doesn’t need a class to represent a graph which includes TSort.

graph = {1=>[2], 2=>[3, 4], 3=>[2], 4=>[]}
each_child = lambda {|n, &b| graph[n].each(&b) }
TSort.each_strongly_connected_component_from(1, each_child) {|scc|
  p scc
}
#=> [4]
#   [2, 3]
#   [1]
