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

Given that we know our syntax error exists somewhere in our frontier, we want to find the smallest possible set of blocks that contain all the syntax errors

Sets the request body to a URL-encoded string derived from argument params, and sets request header field 'Content-Type' to 'application/x-www-form-urlencoded'.

The resulting request is suitable for HTTP request POST or PUT.

Argument params must be suitable for use as argument enum to URI.encode_www_form.

With only argument params given, sets the body to a URL-encoded string with the default separator '&':

req = Net::HTTP::Post.new('example.com')

req.set_form_data(q: 'ruby', lang: 'en')
req.body            # => "q=ruby&lang=en"
req['Content-Type'] # => "application/x-www-form-urlencoded"

req.set_form_data([['q', 'ruby'], ['lang', 'en']])
req.body            # => "q=ruby&lang=en"

req.set_form_data(q: ['ruby', 'perl'], lang: 'en')
req.body            # => "q=ruby&q=perl&lang=en"

req.set_form_data([['q', 'ruby'], ['q', 'perl'], ['lang', 'en']])
req.body            # => "q=ruby&q=perl&lang=en"

With string argument sep also given, uses that string as the separator:

req.set_form_data({q: 'ruby', lang: 'en'}, '|')
req.body # => "q=ruby|lang=en"

Net::HTTPHeader#form_data= is an alias for Net::HTTPHeader#set_form_data.

Returns whether the HTTP session is to be kept alive.

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

each_strongly_connected_component returns nil.

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 {|scc| p scc }
#=> [4]
#   [2]
#   [3]
#   [1]

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

The iterator version of the TSort.strongly_connected_components 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.each_strongly_connected_component(each_node, each_child) {|scc| p scc }
#=> [4]
#   [2]
#   [3]
#   [1]

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

Creates a State object from opts, which ought to be Hash to create a new State instance configured by opts, something else to create an unconfigured instance. If opts is a State object, it is just returned.

Initializes this object from orig if it can be duplicated/cloned and returns it.

Returns true, if only ASCII characters should be generated. Otherwise returns false.
