When called during a completion (e.g. from within your completion_proc), it will return a string containing the character used to quote the argument being completed, or nil if the argument is unquoted.
When called at other times, it will always return nil.
Note that Readline.completer_quote_characters must be set, or this method will always return nil.
Verify compaction reference consistency.
This method is implementation specific. During compaction, objects that were moved are replaced with T_MOVED objects. No object should have a reference to a T_MOVED object after compaction.
This function doubles the heap to ensure room to move all objects, compacts the heap to make sure everything moves, updates all references, then performs a full GC. If any object contains a reference to a T_MOVED object, that object should be pushed on the mark stack, and will make a SEGV.
When invoked with a block, yield all repeated permutations of length n of the elements of the array, then return the array itself.
The implementation makes no guarantees about the order in which the repeated permutations are yielded.
If no block is given, an Enumerator is returned instead.
Examples:
a = [1, 2] a.repeated_permutation(1).to_a #=> [[1], [2]] a.repeated_permutation(2).to_a #=> [[1,1],[1,2],[2,1],[2,2]] a.repeated_permutation(3).to_a #=> [[1,1,1],[1,1,2],[1,2,1],[1,2,2], # [2,1,1],[2,1,2],[2,2,1],[2,2,2]] a.repeated_permutation(0).to_a #=> [[]] # one permutation of length 0
When invoked with a block, yields all repeated combinations of length n of elements from the array and then returns the array itself.
The implementation makes no guarantees about the order in which the repeated combinations are yielded.
If no block is given, an Enumerator is returned instead.
Examples:
a = [1, 2, 3] a.repeated_combination(1).to_a #=> [[1], [2], [3]] a.repeated_combination(2).to_a #=> [[1,1],[1,2],[1,3],[2,2],[2,3],[3,3]] a.repeated_combination(3).to_a #=> [[1,1,1],[1,1,2],[1,1,3],[1,2,2],[1,2,3], # [1,3,3],[2,2,2],[2,2,3],[2,3,3],[3,3,3]] a.repeated_combination(4).to_a #=> [[1,1,1,1],[1,1,1,2],[1,1,1,3],[1,1,2,2],[1,1,2,3], # [1,1,3,3],[1,2,2,2],[1,2,2,3],[1,2,3,3],[1,3,3,3], # [2,2,2,2],[2,2,2,3],[2,2,3,3],[2,3,3,3],[3,3,3,3]] a.repeated_combination(0).to_a #=> [[]] # one combination of length 0
Returns any backtrace associated with the exception. This method is similar to Exception#backtrace, but the backtrace is an array of Thread::Backtrace::Location.
This method is not affected by Exception#set_backtrace().
Creates module functions for the named methods. These functions may be called with the module as a receiver, and also become available as instance methods to classes that mix in the module. Module functions are copies of the original, and so may be changed independently. The instance-method versions are made private. If used with no arguments, subsequently defined methods become module functions. String arguments are converted to symbols.
module Mod def one "This is one" end module_function :one end class Cls include Mod def call_one one end end Mod.one #=> "This is one" c = Cls.new c.call_one #=> "This is one" module Mod def one "This is the new one" end end Mod.one #=> "This is one" c.call_one #=> "This is the new one"
Returns the fractional part of the day.
DateTime.new(2001,2,3,12).day_fraction #=> (1/2)
Returns the fractional part of the second.
DateTime.new(2001,2,3,4,5,6.5).sec_fraction #=> (1/2)
Clone internal hash.
Set options. Takes the same argument as GetoptLong.new.
Raises a RuntimeError if option processing has already started.
‘get_option’ is an alias of ‘get’.
‘each_option’ is an alias of ‘each’.
Returns the Ruby source filename and line number of the binding object.
Raises PStore::Error if the calling code is not in a PStore#transaction.
List of options that will be supplied to RDoc
Returns the Ruby source filename and line number containing this proc or nil if this proc was not defined in Ruby (i.e. native).
Returns the Ruby source filename and line number containing this method or nil if this method was not defined in Ruby (i.e. native).
Returns the Ruby source filename and line number containing this method or nil if this method was not defined in Ruby (i.e. native).
Returns the execution stack for the target thread—an array containing backtrace location objects.
See Thread::Backtrace::Location for more information.
This method behaves similarly to Kernel#caller_locations except it applies to a specific thread.
Value from exception raised on the :raise event
Compiled instruction sequence represented by a RubyVM::InstructionSequence instance on the :script_compiled event.
Note that this method is MRI specific.
Returns the current execution stack—an array containing backtrace location objects.
See Thread::Backtrace::Location for more information.
The optional start parameter determines the number of initial stack entries to omit from the top of the stack.
A second optional length parameter can be used to limit how many entries are returned from the stack.
Returns nil if start is greater than the size of current execution stack.
Optionally you can pass a range, which will return an array containing the entries within the specified range.
Initializes the MonitorMixin after being included in a class or when an object has been extended with the MonitorMixin
Returns the source file origin from the given object.
See ::trace_object_allocations for more information and examples.
