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]
Fetch the trailing comments of the value.
Configure the trailing comments field for this repository and return self.
Build a diagnostic from the given prism parse warning.
Returns true if there is a comma between the two locations.
returns the directory nesting of the extension, ignoring the first part, so “ext/foo/bar/Cargo.toml” becomes “foo/bar”
@foo &&= bar
becomes
@foo && @foo = bar
@foo ||= bar
becomes
@foo || @foo = bar
@foo += bar
becomes
@foo = @foo + bar
Search through all unresolved deps and sub-dependencies and return specs that contain the file matching path
.
Return current keep_script_lines
status. Now it only returns true
of false
, but it can return other objects in future.

It set keep_script_lines
flag. If the flag is set, all loaded scripts are recorded in a interpreter process.

Hook method to return whether the obj can respond to id method or not.
When the method name parameter is given as a string, the string is converted to a symbol.
See respond_to?
, and the example of BasicObject
.
Returns a list of the public instance methods defined in mod. If the optional parameter is false
, the methods of any ancestors are not included.
Returns a list of the protected instance methods defined in mod. If the optional parameter is false
, the methods of any ancestors are not included.
Returns true
if the given class variable is defined in obj. String
arguments are converted to symbols.
class Fred @@foo = 99 end Fred.class_variable_defined?(:@@foo) #=> true Fred.class_variable_defined?(:@@bar) #=> false
Similar to instance_method, searches public method only.
Returns true
if the named private method is defined by mod. If inherit is set, the lookup will also search mod’s ancestors. String
arguments are converted to symbols.
module A def method1() end end class B private def method2() end end class C < B include A def method3() end end A.method_defined? :method1 #=> true C.private_method_defined? "method1" #=> false C.private_method_defined? "method2" #=> true C.private_method_defined? "method2", true #=> true C.private_method_defined? "method2", false #=> false C.method_defined? "method2" #=> false
Yields while console input events are queued.
This method is Windows only.
You must require ‘io/console’ to use this method.
Invoked as a callback whenever a singleton method is added to the receiver.
module Chatty def Chatty.singleton_method_added(id) puts "Adding #{id.id2name}" end def self.one() end def two() end def Chatty.three() end end
produces:
Adding singleton_method_added Adding one Adding three
Invoked as a callback whenever a singleton method is removed from the receiver.
module Chatty def Chatty.singleton_method_removed(id) puts "Removing #{id.id2name}" end def self.one() end def two() end def Chatty.three() end class << self remove_method :three remove_method :one end end
produces:
Removing three Removing one
