Subject: [ruby-dev:44952] [ruby-trunk - Bug #5728] SystemExit.new(bool, message)


Issue #5728 has been updated by Motohiro KOSAKI.


> I think SystemExit.new should accept a bool.

We have two choice and both are a lot of confusable.

1) true => EXIT_SUCCESS, false => EXIT_FAILURE
   People may dislike it becuase true mapped 0 and false mapped 1.
2) true => EXIT_FAILURE, false => EXIT_SUCCESS
   People also may dislike it. Because true usually isn't used for failure.

As far as EXIT_SUCCESS==0, I doubt we can make natural conversion.

I found SystemExit.new doesn't take a bool as exit status:

It works well if an integer is given for status.

  % ./ruby -e 'SystemExit.new(0, "msg")' 
  % ./ruby -e 'SystemExit.new(1, "msg")'  

But it doesn't work if the status is a bool.

  % ./ruby -e 'SystemExit.new(true, "msg")'
  -e:1:in `initialize': wrong number of arguments (2 for 0..1) (ArgumentError)
	  from -e:1:in `initialize'
	  from -e:1:in `new'
	  from -e:1:in `<main>'
  % ./ruby -e 'SystemExit.new(false, "msg")'
  -e:1:in `initialize': wrong number of arguments (2 for 0..1) (ArgumentError)
	  from -e:1:in `initialize'
	  from -e:1:in `new'
	  from -e:1:in `<main>'

  % ./ruby -v
  ruby 2.0.0dev (2011-12-08 trunk 33981) [x86_64-linux]

I think SystemExit.new should accept a bool.
