Converts this AvailableSet into a RequestSet that can be used to install gems.

If development is :none then no development dependencies are installed. Other options are :shallow for only direct development dependencies of the gems in this set or :all for all development dependencies.

Make directories for index generation

Returns true if the MKD command may be used to create a new directory within the directory.

Corrects path (usually returned by ‘URI.parse().path` on Windows), that comes with a leading slash.

Extract platform given on the command line

Removes the named instance variable from obj, returning that variable’s value. String arguments are converted to symbols.

class Dummy
  attr_reader :var
  def initialize
    @var = 99
  end
  def remove
    remove_instance_variable(:@var)
  end
end
d = Dummy.new
d.var      #=> 99
d.remove   #=> 99
d.var      #=> nil

DO NOT USE THIS DIRECTLY.

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 local IP addresses as an array.

The array contains Addrinfo objects.

pp Socket.ip_address_list
#=> [#<Addrinfo: 127.0.0.1>,
     #<Addrinfo: 192.168.0.128>,
     #<Addrinfo: ::1>,
     ...]

Returns reference counter of Dispatch interface of WIN32OLE object. You should not use this method because this method exists only for debugging WIN32OLE.

Returns true when OLE object has OLE method, otherwise returns false.

ie = WIN32OLE.new('InternetExplorer.Application')
ie.ole_respond_to?("gohome") => true

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

Prints all threads in @thread_list to @stdout. Returns a sorted array of values from the @thread_list hash.

While in the debugger you can list all of the threads with: DEBUGGER__.thread_list_all

(rdb:1) DEBUGGER__.thread_list_all
+1 #<Thread:0x007fb2320c03f0 run> debug_me.rb.rb:3
 2 #<Thread:0x007fb23218a538 debug_me.rb.rb:3 sleep>
 3 #<Thread:0x007fb23218b0f0 debug_me.rb.rb:3 sleep>
[1, 2, 3]

Your current thread is indicated by a +

Additionally you can list all threads with th l

(rdb:1) th l
 +1 #<Thread:0x007f99328c0410 run>  debug_me.rb:3
  2 #<Thread:0x007f9932938230 debug_me.rb:3 sleep> debug_me.rb:3
  3 #<Thread:0x007f9932938e10 debug_me.rb:3 sleep> debug_me.rb:3

See DEBUGGER__ for more usage.

Checks for a method provided by this the delegate object by forwarding the call through _getobj_.

Handle BasicObject instances

The block passed to this method will be called just before running the RDoc generator. It is allowed to modify RDoc::Task attributes inside the block.

Returns the status of the global “report on exception” condition.

The default is true since Ruby 2.5.

All threads created when this flag is true will report a message on $stderr if an exception kills the thread.

Thread.new { 1.times { raise } }

will produce this output on $stderr:

#<Thread:...> terminated with exception (report_on_exception is true):
Traceback (most recent call last):
        2: from -e:1:in `block in <main>'
        1: from -e:1:in `times'

This is done to catch errors in threads early. In some cases, you might not want this output. There are multiple ways to avoid the extra output:

• If the exception is not intended, the best is to fix the cause of the exception so it does not happen anymore.

• If the exception is intended, it might be better to rescue it closer to where it is raised rather then let it kill the Thread.

• If it is guaranteed the Thread will be joined with Thread#join or Thread#value, then it is safe to disable this report with Thread.current.report_on_exception = false when starting the Thread. However, this might handle the exception much later, or not at all if the Thread is never joined due to the parent thread being blocked, etc.

See also ::report_on_exception=.

There is also an instance level method to set this for a specific thread, see report_on_exception=.

Returns the new state. When set to true, all threads created afterwards will inherit the condition and report a message on $stderr if an exception kills a thread:

Thread.report_on_exception = true
t1 = Thread.new do
  puts  "In new thread"
  raise "Exception from thread"
end
sleep(1)
puts "In the main thread"

This will produce:

In new thread
#<Thread:...prog.rb:2> terminated with exception (report_on_exception is true):
Traceback (most recent call last):
prog.rb:4:in `block in <main>': Exception from thread (RuntimeError)
In the main thread
