Add separator in summary.
Searches key in @stack for id hash and returns or yields the result.
Iterates the given block over all prime numbers.
ubound
Optional. An arbitrary positive number. The upper bound of enumeration. The method enumerates prime numbers infinitely if ubound is nil.
generator
Optional. An implementation of pseudo-prime generator.
An evaluated value of the given block at the last time. Or an enumerator which is compatible to an Enumerator if no block given.
Calls block once for each prime number, passing the prime as a parameter.
ubound
Upper bound of prime numbers. The iterator stops after it yields all prime numbers p <= ubound.
Returns the path to the data store file.
Returns a string containing the character represented by the int‘s value according to encoding.
65.chr #=> "A" 230.chr #=> "\346" 255.chr(Encoding::UTF_8) #=> "\303\277"
As int is already an Integer, all these methods simply return the receiver.
Returns self.
Returns 1.
Returns the value as a rational. The optional argument eps is always ignored.
Returns a new set that is a copy of the set, flattening each containing set recursively.
Equivalent to Set#flatten, but replaces the receiver with the result in place. Returns nil if no modifications were made.
Calls the given block once for each element in the set, passing the element as parameter. Returns an enumerator if no block is given.
Creates a Shell object which current directory is set to path.
If a block is given, it restores the current directory when the block ends.
If called as iterator, it restores the current directory when the block ends.
Returns the full path name of the temporary file. This will be nil if unlink has been called.
Creates a temporary file as usual File object (not Tempfile). It doesn’t use finalizer and delegation.
If no block is given, this is similar to Tempfile.new except creating File instead of Tempfile. The created file is not removed automatically. You should use File.unlink to remove it.
If a block is given, then a File object will be constructed, and the block is invoked with the object as the argument. The File object will be automatically closed and the temporary file is removed after the block terminates. The call returns the value of the block.
In any case, all arguments (+*args+) will be treated as Tempfile.new.
Tempfile.create('foo', '/home/temp') do |f|
... do something with f ...
end
Returns the main thread.
Terminates thr and schedules another thread to be run.
If this thread is already marked to be killed, exit returns the Thread.
If this is the main thread, or the last thread, exits the process.
Returns the status of thr.
"sleep"
Returned if this thread is sleeping or waiting on I/O
"run"
When this thread is executing
"aborting"
If this thread is aborting
false
When this thread is terminated normally
nil
If terminated with an exception.
a = Thread.new { raise("die now") } b = Thread.new { Thread.stop } c = Thread.new { Thread.exit } d = Thread.new { sleep } d.kill #=> #<Thread:0x401b3678 aborting> a.status #=> nil b.status #=> "sleep" c.status #=> false d.status #=> "aborting" Thread.current.status #=> "run"
Path of the file being run
Returns internal information of TracePoint.
The contents of the returned value are implementation specific. It may be changed in future.
This method is only for debugging TracePoint itself.

Creates a new Pathname object from the given string, path, and returns pathname object.
In order to use this constructor, you must first require the Pathname standard library extension.
require 'pathname' Pathname("/home/zzak") #=> #<Pathname:/home/zzak>
See also Pathname::new for more information.
Equivalent to:
$stdout.putc(int)
Refer to the documentation for IO#putc for important information regarding multi-byte characters.
