return the stub script text used to launch the true Ruby script

Expire memoized instance variables that can incorrectly generate, replace or miss files due changes in certain attributes used to compute them.

Shows the context around code provided by “falling” indentation

Converts:

  def hello
    it "foo" do
  end
end

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.

Inspect a InstanceVariableWriteNode node.

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]
